Is Artificial lawn harmful to the body?

The Artificial lawn produced by qualified raw materials is not harmful to the human body, so it is recommended to choose Artificial lawn. The first choice depends on the strength, scale and brand of the production plant.Essence

Is the fake lawn poisonous?

The Artificial lawn is chemical, which is actually the problem that everyone is worried about. Maybe everyone does not know that the chemicals used for artificialcasters are not harmful. Its main raw material isPP(Polypropylene) andPE(Polyethylene) is also a type of plastic. These raw materials have been tested by strict quality, non -toxic and pollution, and many testing standards have reached international standards.Imagine that we can usually use plastic bowls to eat some snack desserts, so walking on it will not have any impact on the human body.And artificial lawns can also prevent bacteria from breeding, so there are still few bacteria on artificial lawns.And it can also prevent direct touch with people and the ground, and also protect the soil well, allowing people to avoid soil damage.

Plastic lawn is harmful to the human body

1, Lawn to maintain toxic side effects

Once the Artificial lawn is paved, it does not need to be trimmed and cultivated in the later stage, which is simple and convenient to maintain.In fact, in order to keep the lawn tidy and beautiful, avoid weeds to grow on it, and at the same time to disinfect, it is generally sprayed with herbicides and sterilizers when maintenance.Both herbicides and sterilizers are biological killing agents, which are usually used to inhibit plant growth and prevent various pathogenic microorganisms.But they all belong to chemical products and have certain toxic and side effects.

In addition to its own toxicity, the excessive use of these agents can also enhance the bacteria resistance.Because there are many bacteria on the lawn, amplifier -resistant oxygenus Golden Polygangiola (MRSA) The easiest to infect students.This is a very anti -drug germ that can resist all penicillin.When students are playing on the lawn and accidentally falling and bumping, they will inevitably have abrasions and scratches. As long as the Skin is broken, the germs will take advantage of it, causing some serious diseases.

2, Temperature hardness is not conducive to playing

The Artificial lawn does not absorb heat, and only reflects the sun.In high temperature in summer, the surface temperature on the lawn can soar80OC ~ 90OCabout.This high temperature can easily hurt students, even if wearing sports shoes, they may damage their feet due to high temperature.Of course, sprinkler can cool down, but the effect can only be maintained20In minutes, it disappeared.In contrast, the natural lawn will not be like this at all.40OCEssence

In addition, artificial lawns are generally laid on concrete, cement land or compact soil. This"Base"As a result, the lawn's hardness is very high, far exceeding the natural lawn, and it will become harder with temperature, use time and maintenance.The higher the hardness, once the student is injured, the more likely to suffer from cerebral vibration.

3The raw materials are carcinogenic particles

The greatest harm of Artificial lawn comes from its manufacturing raw materials.Artificial lawn is generally composed of three parts: foundation, artificial grass and filling.The foundation is the basis of the entire lawn and a backing material.artificial grass is installed on the foundation.In order to increase the elasticity of the entire lawn and also to support the leaves of artificial grass, people will also place filling on the lawn, which is generally black powder tiny particles.

The color of artificial grass is dyed by pigments, containing a large amount of pigment, which may include a variety of metal elements such as lead and titanium.The black filling particles on the Artificial lawn are made of crushing with waste tires.Modern commonly used tires are a mixture, including natural rubber, synthetic rubber, carbon black and other oil -making products.This also contains a variety of metal elements, such as cadmium, lead, zinc.Lead has neurotoxicity, and excessive intake can cause nervous disorders; some chemicals contained in the tires are recognized as carcinogens; charcoal and black are made of oil as raw materials, which are adsorbed.Chemicals may be attracted by charcoal black.

4The disease that may be caused by particulate matter

In general, there are two main diseases caused by artificial lawns: cancer and nerve disorders.If there are many cases of cancer in a certain period and place, there are many cases of cancer, which is medically referred to as a cancer case group.

The harm of the nervous system comes from lead.In addition to the raw materials of artificial lawns, lead also exists in the logo line and various white threads of the plastic runway next to the lawn. These pigments are lead.The early symptoms of lead poisoning are nerve weakness, manifested as dizziness, weakness, and memory loss.This will seriously damage the healthy growth of students in physical and psychological.

In fact, through the above introduction, it is not difficult to see that the Artificial lawn with guaranteed quality is not harmful to our human body. Therefore, when choosing a Artificial lawn, for everyone's health, you cannot use low -cost and inferior plastic lawns.If you are still uneasy, then we must clean up the lawn regularly, so that we can protect the lawn well.We can also check our own body often, which is needed whether we use the lawn whether we use the lawn.Now I believe everyone should have a better understanding of the Artificial lawn!

[Men Gang basketball shoes] Can I run the basketball shoes?

Can I run the basketball shoes?

Netizen 1: Most of basketball shoes are high -top types. High -top -like shoes can easily cause strain of the feet's tendons, not adapting to the ankle, stretching, etc.;

Netizen 2: There are a few basketball shoes that belong to the low gang but still cannot be used as running shoes. The inherent characteristics of basketball shoes are heavy. This weight gives the unique features of basketball shoes: shock absorption, bouncing, and Smooth landing.The use of running shoes increases the weight of the body and feet, causing inconvenience to run;

Netizen 3: The soles of basketball shoes are wear -resistant and solid, because the pattern of the soles of its shoes is dense. It is used as a Running.

Which position player is suitable for basketball shoes?

Zhong Gang basketball shoes are suitable for people who swing on the front line, such as the role between striker and guards.The high gang is higher than the ankle, and the middle gang is just the ankle. The low gang can expose the ankle.Traditional basketball shoes generally speaking, the higher the shoes are better for the ankle, but at the same time, the flexible rotation of the ankle is more restricted.

The Buddha beads are plants under the family of Chrysanthemum, which are native to South Africa.The beads are fleshy, spherical to spindle -shaped, and there is a transparent longitudinal pattern in the center of the leaf, and there is a slightly pointed protrusion at the end of the tail.The stems are Hanging or the soil surface grows, so it is mostly cultivated as a suspension plant.

Buddha beads belong to succulent, native to South Africa.The leaf meat, the spherical to the spindle shape, the leaf center has a transparent longitudinal pattern, and there is a slightly pointed protrusions at the end of the tail.The stems are Hanging or the soil surface grows, so it is mostly cultivated as a suspension plant.Seeing that the fleshy meat like beads never thought about it and would bloom.

Cultivation technology

1. Soil: The root system of the plant is very shallow, which can be placed shallowly. Generally, the bottom hole is used with tiles, and a layer of cornography or coarse sand are paved to increase the breathability and water filtration (especially the plastic potted plants that are currently commonly used).The soil is best to use rotten leaf soil (the fallen leaves of autumn and winter trees are mixed with a certain amount of soil or a certain sand. The soil and the sand are about 1: 3).

2. Light: Buddha beads like a semi -yin environment, the light is too weak and grows slowly, and the color is dim.If the light is too strong, it will cause the pearl body due to exposure, causing the dried orchid to scorch.The growth temperature is around 12 to eighteen degrees, and it is not less than five degrees in winter.

3. Temperature: Sexuality is warm and humid, which is cold -resistant (it can withstand low temperatures of 0 C when cultivated in the Jianghuai area), high temperature resistance, the optimal temperature is about 20 C to 28 C.It grows slowly at high temperature and low temperature, especially in the high temperature environment above 30 C. It is almost dormant, and less watering should be watered, otherwise it is easy to rot.This is also one of the keys to cultivation.

4. Watering: Due to the leaf meat, juicy, drought resistance, watering should be dry and not wet during cultivation. This is one of the key to success.When the weather is dry, you can spray the leaves and vines to make up for the lack of moisture, and keep the beads full of green.Compared to half yin, the exposure may burn the bead body, and the light is too weak and does not grow strong.

5. Fertilization: The strong growth of spring and autumn should be applied thinly, and it is often sprayed with 1-3 % of nitrogen fertilizer and potassium dihydrogen phosphate on the leaf surface.

6. Pruning: During the repair, not just cut off the excess part, but start the trimming from the edge of the Flower pot or the edge of the Flower pot.It is the "top" that everyone usually says.There will be separate branches on the cut place, the more branches of the top, the more branches, and the more branches will naturally explode.

7. Preventive diseases and insect pests: Few pests and insect pests.The aphids in spring are one of them. Wiped it in time or spray 1500 times oxidative music to kill; mites in summer and autumn are second, and 1000 times trichlosterol may be killed.Pay attention to ventilation and increase the humidity of the leaf surface to reduce infection mites.

8. Breeding: The succulent beads can be cut and breed, and the branches are very easy to take root. You can cut a few sections in spring and autumn. Half are buried into the sand or loose soil, keeping moist but not accumulating water, and you will quickly take root for planting.

precautions for the breeding of polyphonic beads

1. From March to December each year is the growth period of the plant. There is a short half dormant in summer. If the light is less likely to grow long, the stems will become fragile, and the spacing between the leaves will be opened for a long time.In plants that grow in full sunshine, the plant types are stubborn strong, the leaves are full, and the spacing of the leaves will be relatively close.

2. Keep the soil slightly wet to avoid stagnant water during the growth period.The soil can be mixed with cornography and a small amount of perlite, with a ratio of about 6: 3: 1.

3. Keep as much as possible in winter as much as possible, otherwise the temperature is too low to be frostbite and die, which is less resistant to frost.When the summer temperature exceeds 35 C, the entire plant will grow slowly.At this time, watering should be reduced to prevent rotten rot from the root of the pot soil.And strengthen ventilation, appropriate shades, avoid the sun exposure.

4. Avoid long -term rain during cultivation, otherwise the stems will be rotten.

5. The Buddha beads are still relatively fast. It is almost the same for changing the pot in 1 to 2 years. The pot is changed before watering in the first spring.The Chairman of the Buddha has a lot of branches.Breeding can cut the long section directly. The cuttings are very simple. Take a section of the healthy Buddha bead and cut the dry wound cuttings in a slightly humid sand soil. You can also put it directly on the soil surface.

1. How much is a Baseball uniform?

The price of Baseball uniforms is similar to that of other clothing.The cheap ones are about 100 yuan, and the expensive ones are generally around 200-400 yuan. Some fabrics and brands can reach thousands of yuan.

The price of Baseball uniforms mainly depends on the quality, fabrics, craftsmanship and brand awareness of clothes.Rowing suitThe higher the brand, the higher the brand, and the price is higher and higher; the fabrics, different fabrics, and costs are different, so it will also affect the price; the process, different craftsmanship will also affect the price.

2. How to choose the right Baseball uniform based on the figure

1. Petite body

Suitable:Short stitching design Baseball uniform.

This style of Baseball jackets can highlight tall and petite figures, and have exquisite and short characteristics in the matching, so as to effectively attract people's sight to the upper body.

Taboo:The fat mid -length Baseball uniform or pure black Baseball uniform.

The fat mid -length models will make you more embarrassed, and the pure black light absorption effect will make you shorter.

2. Pear shape

Suitable:Mid -length Baseball uniform.

The thin pear -shaped figure on the thin and fat needs to have a strong concealment style to modify the characteristics of wide hips. Loose and medium -length Baseball jackets can perfectly cover the lack of body curve.Handsome is the first choice for pear -type body MM.

Taboo:Short Baseball uniform.

Short Baseball uniforms will make the upper body look light and light, and highlight the difference in the proportion of the upper and lower figures. It is necessary to resolutely eliminate it.

3. Paper body figure

Suitable:Printing Baseball uniforms, patterns or colorful Baseball uniforms.

Paper people should choose a tension Baseball jacket. The eye -catching patterns, prints, or colors can successfully grab the eyeballs, add a sense of presence, and let you easily get rid of the thin small board.

Taboo:A single dark Baseball uniform.

The mysterious light -absorbing color has an obvious thin effect, and it will be thinner.

4. Little belly & amp; bucket waist

Baseball uniforms are a must -have for this body. Because the outline of the Baseball uniform is mostly a loose body shape of the littering, this structure provides a hidden space for the small belly and the bucket waist, so the people who worry about it quickly hurry upStart.

5. Short neck

Because the collar type of Baseball uniforms is relatively special, the smaller neckline is demanding on the shoulder and neck ratio, so MM, which is not long enough for the neck and neck, must choose Baseball uniforms with caution.

Where is the easiest to leak in the sun room?

1 As well as The connection between the frame and glass and the wall

Because many sun rooms are built on the wall, there are many walls facing walls, so that it is very easy to leak at the connection between the wall and the glass.There are some walls that have inner lining thermal insulation materials. When making shelves, if the ingredients are not close to the wall, and waterproof, it can easily lead to the sun room." Ten nine missions " Essence

2 , Framework construction is not strong

Some irregular sun room production companies cut corners and use non -national standard iron or aluminum pipes. The strength is not enough. The overall frame of the long sun room is deformed, causing the glue to crack and leak water.

3 ,water proof The glue is not selected well or did not fight well

Everyone knows that the Sunshine room is composed of frame, hollow glass, and broken bridges, aluminum doors and windows. The filling between the between it is glass glue, and the brush layer on the wall is exposed to the sun. The paint will gradually fall off and loose.Beat on the wall and glass The adhesive seams were slowly peeling and falling off, and the problem of leakage occurred in the cracks.

4 As well as waterproof glue failure produces cracks

The brush layer on the wall was exposed to the sun, and the coatings gradually shed and loosened. The gel seams that previously hit the wall and glass connection slowly peel and fall off, and the cracks caused water leakage.

Sunshine room leak Seepage Solution

1 After the Sunshine room framework is completed, if there is a place to connect with the wall, it is necessary to remove the coatings on the original wall so that the glue and the wall can be firmly connected.After the glue is tapping, the wall is slotted on the wall above the load, and the raindrop plate can be installed to ensure that the double -layer waterproof is not leaked.

2 The Sunshine room plays a very important role in waterproof. The top of the sun room is generally structural glue and weather resistance. In the gap between the top covering, first hit a layer of structural glue, and then attach a layer of weathering glueThis can make the frame and cover firmly connect.Between the doors and windows and the frame, it is best to give up 3-5mm In the gap, the glue can be sticking to the gap between the doors and windows and the frame, so that the structure is stronger and the waterproof effect is better.

3 The sun room is different from the doors and windows. It is formed by the overall frame structure, and the top of the sun room is generally high, and the force is large. Therefore, you must choose a good quality framework material and pay attention to the quality of construction.

4 The ending of the sun room is important.The glue between the doors and windows and the frame must not be omitted. The joints of the door and window profiles, and the joints between the frames, as long as there is a gap, may leak rain.

How to do drainage in the sun room

1 Reasonable organizationDrainage system

The reasonable organization of the drainage system is mainly to determine the drainage direction of the Sunshine room and the eaves drainage method.In order to quickly eliminate rainwater, the drainage direction of the sun room should be clearly clarified to reduce the turning point.

2 , Determine the appropriate drainage slope

In order to exclude rainwater, the Sunshine room requires a certain amount of drainage slope. The larger the slope, the smoother the drainage.However, when the slope is quite large, it will cause adverse conditions to the construction and structure layout, so it is important to determine a suitable slope according to specific requirements.The slope of the sun room is determined by various factors. Among them, the amount of precipitation in the area, the body shape, size, and structural form of the Sunshine house have the greatest impact on the slope of the sun room.The important factor, in general, the angle between the slope of the sun room and the level is not less than 18 Degree, not greater than 45 It is appropriate.
