Third, the venue test of artificial grass and natural grass:

1 Slope: Slope of the artificial grass is less than 1.0% ; Natural lawn slope requires less than 0.5% Essence

2 , Flat degree: artificial grass flat flatness 3 Mi Niandong 10 Millimeter, 300 Small within millimeter 2 Millimeter; natural lawns are flat and the qualified value is not greater than 30mm The best value is not greater than 20 mm Essence

3 Water seepage rate: Artificial lawn base infiltration performance is greater than 180 Millimeter / / Hours; natural garries and ground base penetration performance greater than 180 Millimeter / / Hour.

What are the advantages and disadvantages of natural lawns and artificial lawns

Advantages of natural lawns:

1 The natural lawn has unparalleled characteristics. The soft texture of the natural lawn makes the surface of the lawn have appropriate smoothness. The heat generated by friction is within the human body tolerance and will not cause damage to the human body.

2 The natural lawn has moderate hardness and return elasticity. Athletes can arbitrarily make various technical actions without worrying about severe damage because of falling.

3 The natural lawn is composed of green plant gay grass. The stems and leaves are soft and soft. When the human body rubs with it, it will not generate electrical electricity.

Natural lawn disadvantages:

Natural lawns are easily affected by weather. There is no Artificial lawn, high cost, and trouble.

The Artificial lawn is a lawn made of non -life plastic chemical fiber products as raw materials.It is an important way to solve natural lawns such as high strength and extremely unfavorable growth conditions such as excessive strength and extremely unfavorable growth conditions.

Advantages of Artificial lawn:

Compared with natural lawns, artificial lawns have very obvious advantages.

1 , Whether in the cold winter or hot summer, it can be used normally. It is affected by rain and snow, and it is all -weather. 24h Use, especially suitable for school football field or various training grounds with high frequency.

2 , Good durability, a period of normal use of artificial lawns can be reached 10 Over the year.

3 , Low -stage management and maintenance costs, simple maintenance, no need to plant Items No need to trim Items No water Items The indoor can still be green, and winter does not change yellow.

4 The surface layer can be recycled and reuse, which has environmental protection performance.

5 Many international top competitions and domestic competitions are carried out in the Artificial lawn, which will provide greater consistency in terms of results.

6 , Will not cause allergic reactions.

7 The entire lawn is uniform and consistent, and it will not have a bare nude area like a natural lawn.

There are also some obvious disadvantages of artificial lawns:

1 Because most of the chemical fiber materials are used, and asphalt or concrete are used as the grassroots, their surface hardness is large, the cushioning performance is poor, the rebound rate is high, the football rolling distance is short.Back -up strength is easy to cause athlete's ankle or knee injury, which makes the injury rate of the ankle or knee joint on the Artificial lawn is higher than that of natural lawns.

2 The surface temperature changes on the surface of the Artificial lawn is large. If exposed to extreme temperature or under the irradiation of strong ultraviolet rays, some chemicals in the Artificial lawn will change, causing it to change the characteristics in a short period of time, which will be athlete to athletes.Athletic status and environment have a great impact.

3 The Artificial lawn has a corrosion agent and causes some damage to the athlete's body.

The Artificial lawn is an analog lawn made of plastic chemical fiber products as raw materials.It can be used all over the weather, which is affected by rain and snow weather; simple maintenance, low maintenance costs; environmental protection of materials, recycling and reuse of surface layers, etc., are irreplaceable by natural lawns.Therefore, it is very suitable for the use of primary and secondary school sports fields or various training grounds with high frequency. Therefore, artificial lawns are more popular than natural lawns, and more people choose artificial lawns.

Advantages and characteristics of Artificial lawn

First, clean hygiene:

Many parents think that there are more bacteria on the lawn, because the children's resistance ability is poor, and it is not suitable for playing on it. Therefore, these real lawns are gradually replaced by Artificial lawn.There are many benefits to laying artificial lawns. Not only are they safe and healthy, they will not become bare to trample.

Second, all heavenly:

The Artificial lawn is basically not affected by weather and regions. It can be used in extreme climate areas such as high cold, high temperature, and plateau, and has a long service life.

Third, multi -purpose:

The color of artificial lawns is diverse, and durable and non -fading can be matched with the surrounding environment and building complexes. It is a better choice for sports venues, leisure courtyards, roof gardens and other places.

Fourth, laying and maintenance:

Artificial lawn laiding has low requirements for the foundation, and can be constructed on asphalt and cement and short cycles.It is especially suitable for the construction of middle and elementary school venues with long training time and high density.The Artificial lawn is convenient for maintenance, the water seepage performance is good, and it is particularly wear -resistant.

Fifth, excellent physical chemical performance:

After hundreds of thousands of wear trials, the fiber weight is lost by only hundreds of thousands of times2%-3% EssenceIn addition, the tensile, water seepage, and elasticity are high, and after heavy rain 50 It can be drained in about minutes.

Sixth, good security:

The use of the principles such as medicine and sports can make the athletes be protected when they exercise on the lawn, and the ligament, muscles, joints, etc. are protected, and the collision power and friction when they fall are greatly reduced.

Seventh, reduce the workload:

After laying the Artificial lawn, the workload of the staff also reduces a lot. It only needs to be checked regularly to repair the uneven places.

It is worth mentioning that the various strokes of the Artificial lawn sports venue have been formed with white grass seedlings at one time during production.It belongs to environmentally friendly products. It does not contain harmful substances and has noise absorption.The production uses a number of modern science and technology, so that the product's tensile strength, firmness, flexibility, wear resistance, anti -aging, and color fastness have reached a considerable level.

How to buy Artificial lawn

1, Observe the shape of the grass:

There are many types of grass silk,U type, m Type, diamond -shaped, stems, no stems, and so on.The larger the width of the grass, the more materials are.If the grass is added to the stem, it means that the upright type and the return elasticity is better.Of course, the higher the cost.The price of such lawns is usually more expensive.The turf is consistent, Smooth, and no messy silk, indicating that the grass is elastic and the toughness is good.

2 , Observe the background back:

If the back of the lawn is black and it looks a bit like a custard, it is universal butyor phenyl gum; if it is green, it looks like a leather, it is higher -endSPU Back glue.If the bottom cloth and glue look thick, generally indicate that there are many materials, the quality is relatively good, it looks thin, and the quality is relatively poor.If the back of the back is thin and uniform, the color is consistent, and there is no primary color of the grass, indicating that the quality is better; thin and uneven, colored, and leakage of grass silk primary colors, indicating that the quality is relatively poor.

3 , Touch the grass feel:

Most people have to look at the grasshills when they touch the grass, and they are not comfortable with their feelings.But in fact, the soft and comfortable lawn is the poor lawn.You know, the lawn is used in the daily use of the lawn, and it rarely uses the Skin to contact directly. The hard grass is just powerful, with greater reflection of elasticity and toughness.Broken.It is very easy to make grasshills. It is very difficult to make a straight and high bomb. It really needs high -tech and cost.

4 , To see the anti -pull rate:

The law of the lawn is one of the main technical indicators of the lawn, which can be measured by the method of pupae.Cut a cluster of straw silk with your fingers and pull it out hard. It cannot be pulled out at all. Generally, it is the best; sporadic unplugs, and the quality is okay; if it is not strong, you can pull out more ones.Grass silk, basically poor quality.SPU The adult of the gum -backed gum with 80 % of the power should not be completely unplugged. Generally, the buty phenyl benzene can usually fall off. These are the most visible quality differences between the two gums.

5 , Pressor Shri Test elasticity:

Put the lawn on the table and press it with the palm of the hand. After loosening the palm of the hand, if the grass can be obviously rebounded and restores the original, it means that the grasshopper elasticity and toughness are good.For a few days or longer, then dry in the sun for two days to observe the capability of the lawn to restore the original.

6. Tear back:

Grab the lawn with both hands, tear the bottom back like tearing paper, and it cannot be torn at all, it must be the best; it is difficult to tear and it is better; it is easy to tear, it must not be good.generallySPU With eight percent of adults, the glue is almost not torn; how much the butadhenylene gel can be torn, which is also a difference between the two gums that can be seen obviously.

precautions for the purchase of Artificial lawn

First, raw materials

The raw materials of artificial lawns are mostly polyethylene(PE) , Polypropylene (PP) And nylon (PA) Essence

1 Polyethylene (PE) : The cost is relatively high, the feel is softer, the appearance and sports performance are closer to natural grass. It is widely accepted by users. It is currently the most widely used artificial grass fiber raw material in the market.

2 , Polypropylene (PP) : Grass fiber is harder, simple fibrosis is generally suitable for tennis courts, playgrounds, runways, or decorations, etc., and the abrasion resistance is slightly worse than polyethylene.

3 ,nylon (nylon) : It is the earliest artificial grass fiber raw material and the best Artificial lawn raw material. It belongs to the first generation of artificial grass fiber.Developed countries such as the United States have selected nylon artificial lawns, but the quotation in my country is high, and most customers cannot accept it.

2. The bottom

1 Sulfid wool PP The bottom of the weaving: durable, good anticorrosive performance, good adhesion, easy to be firm in glue and grass lines, the price is PP Woven 3 Times.

2 As well as PP The bottom of the weaving: the performance is average, and the bondage power is weak.At the bottom of the glass (( At the bottom of the grid Cure : Materials such as glass fibers are better helpful for increasing the strength of the bottom and the restraint of grass fiber.

3 As well as PU The bottom: strong anti -aging performance, durable Items Strong adhesion to the grass line, and no smell of environmental protection, but the cost is high, especially imported PU Globes are more expensive.

4 The bottom of the woven type: The bottom of the woven type does not use the bottom lining, and the glue is directly attached to the fiber root. This bottom can simplify the production process and save raw materials.The javelin, etc., but the bottom of the woven type has high requirements for equipment and technology. At present, such products have not yet appeared in China.

Third, glue

1 , Butadienal lactating is the most common material in the Chinese art lawn market. It has good functions, cheap costs, and well -integrated.

2 , Polyuretin (PU) Platin is a world -general material. The strength and bundling force are more than several times that of butyl -butyl, durable, beautiful, not corrosive, moldy and environmentally friendly, but the quotation is more expensive, and its market share in my country is relatively low.

Fourth, product structure identification

1 , Appearance.Bright color, no obvious color difference Items The grass seedlings are flat, the clusters are uniform, the overall is flat, the needle distance is uniformly jumping, and the consistency is good Items The bottom is moderately glued and penetrated into the lining, without leakage and damage.

2 The length of the specifications.In principle, the football field is better and better (( Leisure venue outside Cure The longest grass silk is currently 60mm , It is mainly used for professional football stadiums. The most commonly used in the football field length of the football field is about 30-50mm about.

3 The density of the grass.Evaluate from two perspectives: First, look at the number of grass needles from the back of the lawn. Items Second, look at the line distance from the back of the lawn, that is, the line spacing of the turf. The dense the line distance, the better.

4 , Fiber Fiber's grass fiber and fiber diameter.Common sports grass silk is 5700 As well as 7600 As well as 8800 and 10000 That is to say, the higher the grass fiber fiber, the better the quality of each cluster.The diameter of the fiber is used m Come to calculate, generally 50 150 m between.The larger the diameter of the fiber, the better the diameter, the big diameter is that the grass is thick, wear -resistant, and the small diameter of the fiber seems to be very thin plastic, which is not wear -resistant.The indicators of fibrus are generally difficult to measure, so FIFA generally uses fiber weight indicators.

5 , Fiber quality.The greater the graphic wire with the same unit length, the better.Grass fiber pounds are based on fibrousness, and DTEX Definition as every 10000 The quality of rice fibers is 1 Called by gram 1Dtex EssenceThe larger the grass fiber pounds, the thicker the turf is, the greater the weighing of the grass fiber fiber, the stronger the abrasion ability, and the greater the weighing of grass seedlings fiber, the longer the service life.However, the higher the cost of grass seedlings fiber pounds, the higher the cost, according to the age group of the athletes and the frequency of use, the suitable grass seedlings weigh, it is recommended to choose in large sports venues 11000Dtex The above -mentioned weighing lawn woven lawn.

6 , Other aspects.The Artificial lawn is used to use or to beautify the living environment. Therefore, the most important foot feeling and color quality are the first element of consideration.Whether the trajectory run above meets the requirements of the game.

Fifth, Artificial lawn brand selection

brand is an evaluation and cognition formed by users with strong product quality, good product image, perfect after -sales service, excellent corporate culture, etc.A trust between the establishment and the user.Therefore, when choosing an Artificial lawn brand, you should first understand the history of the brand's development. Whether it has stable product quality assurance, the testing and certification of authoritative institutions at home and abroad, and a complete and professional service system.[top Ten Brands of Artificial Capture & GT; & GT;]

1. How long is the Solar lighting lamp charging?

1. Charging Sunshine for 6-8 hours on sunny days, and the lighting light at night is 8-10 hours.

The sun is 6-8 hours with a cloudy day, and the Lights are turned on at night for 4-6 hours.

2. The benefit of charging Solar lighting is: energy saving and environmental protection, no need to be equipped, installed everywhere, absolutely safe.Automatically turn off the Lights and charge during the day, and automatically turn on the light.When people are approaching, they provide highlights, and people turn colorful and low when they leave, taking into account the needs of lighting and decoration.This product has a variety of working modes to set, and the two function keys are different from the induction and long bright functions, which are simple and clear.

2. Can the Solar lights be charged if there is light?

Sun panels are a device that responds to light and can convert light into electricity.The theoretical light of the Solar panel can be charged in theory, but the effect of too weak light, or the light light effect of light light will be worse, and it can't even detect it.

Solar panels: Solar panels are the core part of the Solar power generation system, and it is also the highest value part of the Solar power generation system.Its role is to convert the radiation capacity of the sun into electrical energy, or send it to the battery to store it, or push the load work.The quality and cost of Solar panels will directly determine the quality and cost of the entire system.

battery: Generally, it is a lead -acid battery. In small and micro systems, nickel -metalized batteries, nickel -cadmium batteries or lithium batteries can also be used.Its role is to store the electric energy emitted by the Solar panel when there is light, and then release it when it is needed.

3. Is Solar lamps that require direct Solar to charge before charging

Solar street lights must not have Solar irradiation to emit light.Principles of the work principle of Solar street lights: Under the control of intelligent controllers during the day of the day, Solar panels are exposed to Solar light to absorb Solar light and convert into electric energy.lighting source power supply to achieve lighting function.The DC controller can ensure that the battery pack is not damaged due to over -charging or excessive release. At the same time, it has functions such as light control, time control, temperature compensation and lightning protection, and anti -polar protection.The Solar street lighting system can ensure the normal work of more than 15 days.

1. How to remove the hook glue

Usually use hook glue, and after a long period of time, the hook glue is removed. At this time, the hook rubber printing will appear in the fit part, which will affect the beauty of the fit part. At this timeIt is obvious, you can apply more, and then use a small shovel to linked the hook printing.

White vinegar contains organic solvents, which can dissolve the polymer ester in the hook glue, which can easily remove the hook glue.

When using white vinegar to remove the hook rubber printing, do not dosage too much. The acidity of white vinegar is harmful to the walls and other places. If you apply too much, it may destroy the material of the fit part and make it show other colors.

two,How to remove the traces of sticky hooks

If there is no white vinegar, you can actually use wind oil essence,Alcohol,acetone,Hand creamWhen it is replaced by items, the effect is similar, and it can be removed in time.

1. Wind oil essence

Pour the wind oil on the tissue and wipe the residue with a paper towel.

2,Alcohol

Pour some alcohol on paper towels (the best industrial alcohol, can also be medical alcohol), the method is the same as wind oil essence.

3,Patthon or nail washing water

The amount of acetone used in this method is small, and it can quickly remove the residual glue, which is easy to completely remove the residual glue, which is more troublesome.

4,Hand cream

Squeeze the hand cream on the residue, and slowly rub with your thumb, you can slowly rub the sticky stubborn glue, but this method is slow and laborious.

What are the types of Outdoor moisture -proof pads?

1. Inflatable moisture -proof pads

The inflatable moisture -proof pad can also be called a gas bed. The inflatable moisture -proof pad was first used in water floating pads in China. Later, some people used as Camping moisture -proof pads.The performance is good, but due to the large volume, heavy quality, and blooming inflatable and exhaust, it is an unused variety in the Outdoor moisture -proof pad family.

2. Automatic inflatable moisture -proof pad

Automatic inflatable moisture -proof pads are nobles of the moisture -proof pad family, high -end products, very good elasticity, and very comfortable to use.The automatic inflatable moisture -proof pad is filled with a sponge that is very compressed and expanded. By squeezing the gas in the sponge, the air mouth is closed to make the pad the semi -vacuum state, and the volume will become smaller.Open the breath, and under the action of external air pressure, the sponge will swell and can automatically suck the air into the pad, so it is called an automatic inflatable cushion.

3. Close foam foam moisture -proof pads

This moisture -proof pad is the most common variety. It uses high -pressure polymerization materials. After foaming, it is cut into a certain thickness sheet according to different specifications, which has become our common moisture -proof pad.This kind of moisture -proof pad is characterized by closed holes and no water absorption. It usually uses 45 times the thickness to cut into 0.8-1.0 thickness, so the weight is extremely light.The price of foam plastic moisture -proof pads is relatively low in price, low durability, the first use of odor, and disadvantages to health.

4. Open hole foam moisture -proof pads

The open -hole foam moisture -proof pad is generally made of expansion of polyuronethylene. There are many subtle air chambers that can allow external air to enter and form isolation layers.The advantage is that it is comfortable, lightweight, and not expensive.The air chamber inside the opening foaming pad can limit the flow of air and achieve a good isolation effect.The disadvantage is that it can absorb water. Once it encounters water, it cannot be used, and it is large, it is not easy to compress, it is not convenient to use. The isolation effect does not have a closed foam moisture -proof pad.

5. EVA tide pad

From its name, we can know the materials it choose. EVA is also known as back force glue. EVA moisture -proof pads and closed -hole foam moisture -proof pads have good elasticity and strong toughness, so the price is also large.It has almost doubled the cost compared with the closed -hole foam moisture -proof pads, but it has greatly improved comfort and durability.But from its appearance, it is difficult for consumers to distinguish between the difference between the two.

6. XPE moisture -proof pad

XPE moisture -proof pad, also known as a half -pores bubble film pad, uses ultra -high -pressure polymerization.Although this material is not as high as pure EVA materials, the strength, toughness, and tensile resistance are much better than the closed foam material, but the water -refusal resistance is not as good as closed materials. ThereforeHigh temperature rigidity is performed to enhance waterproofing.This moisture -proof pad that is treated with cut Skin not only enhances the aesthetic and water -refusal, but also improves the toughness. It is also better because of the groove of the pattern.

How to buy moisture -proof pad products

1. Look at the weather

If the weather is very stable and there will be no low temperature, the requirements for comfort should be more important than the essence. If you cannot master the factors of the weather change, choosing a high moisture -proof pad with high exception is a more insurance choice.

2. Look at comfort

Different moisture -proof pad products have different comfort.The comfort of inflatable moisture -proof pads and automatic inflatable moisture -proof pads are very good. Automatic inflatable moisture -proof pads are more comfortable than inflatable moisture -proof pads, lighter weight, cheaper, and warmer, but the price is expensive.Other moisture -proof pads are similar, and consumers can choose according to their own needs.

3. Look at weight

The more comfortable moisture -proof pads are usually thick and the weight is relatively heavy. If you want to engage in long -distance passing or Hiking, the weight of moisture -proof pads is bound to be an important factor that needs to be considered.

4. Look at the volume

The larger the volume of the moisture -proof pad, the more comfortable you sleep, but for those who travel long distances, the volume of the moisture -proof pad should not be too large, especially the Backpack's accommodation space is not much.

5. Look at the subsidiary design

Some attached designs may affect your decision. Some moisture -proof pads have multiple inflatable rooms, making the thickness of the moisture -proof pads easier to adjust. The moisture -proof pads combined with inflatable pillows make it more comfortable.The cushion can improve thermal insulation and non -slip function, and some are designed with a tapered moisture -proof pad that conforms to the human body to save space.
