1. Can heaven umbrella sunscreen?

Under normal circumstances, ordinary heaven umbrellas can also be sunscreen, but its Sun protection effect is not very good.The role of heaven umbrellas is mainly to cover rain and snow, because umbrellas are mostly made of oil paper, oil cloth or plastic cloth, and its fabric can also cover part of the ultraviolet rays, which can be used for sunscreen in a weaker environment.

However, it is not recommended to use ordinary umbrellas to sunscreen if it is summer, because the Sun protection effect of ordinary umbrellas is not ideal, and the sunlight in summer is very strong, and the ultraviolet rays are also very strong. The umbrella cannot protect our Skin at all.Very inappropriate.

summer sunscreen is best to choose a professional paradise. The Solar umbrella is a kind of umbrella that is mainly used to cover the direct irradiation of Solar light. It has a layer of anti -ultraviolet coating on its surface, which can well cover ultraviolet rays and prevent ultraviolet rays from causing Skin to the Skin to the Skin.Harm.It is best to choose a sun umbrella, and the defense effect is the best.

Second, can heaven and umbrella as a sunscreen umbrella?

Paradise and rainy umbrellas have sunscreen effects and can be used as sunscreen umbrellas.There are many paradise umbrellas on the Internet that are folded, and it is convenient to use when going out.Both the rain or sunlight can be used.Yellow Umbrella is a physical sunscreen in sunscreen measures. The main function is sunscreen, anti -ultraviolet rays, and protecting Skin health.At present, the UPF value of the paradise umbrella in the market is generally between 30 and 40, and only the UPF of some products is 50.When the ultraviolet rays are relatively strong, select the heavenly umbrella with low light transmission and high UPF value, which can play a good sunscreen.Paradise Umbrella brand Products & GT; & GT;

[car Sunset board] Which is good for car sunriography?

The car sunrochem is installed above the driver and the co -pilot header to prevent the sun that prevent the sun.When you use it, you can turn up and down when you turn it down, turn around, that is, the XY shaft.

With the continuous improvement of customers' requirements for Shading boards, materials are: plastic, EPP, PU foam, cardboard, etc., multifunctional Shading boards, with Lights and mirrors.Traditional shade boards can no longer meet the needs of customers.Although traditional car Shading boards can block the sun, it occupies most of the driver's vision.With the development of science and technology, a car LCD Shading plate has now appeared, which can block the sunlight and can not stop the sight.

car sunClassification

car sunrs can be divided into three types: front gear, side gear and rear gear.

car sunFront shade gear

There are not many varieties, generally there are two types of aluminum foil and non -woven fabrics.The general "light board" type and pattern type of aluminum foil are generally 60*130cm in size, suitable for most small cars.The hot weather can out the aluminum foil outside to ensure the reflection of the sun. It is best to choose a suction cup with a sunshade. Do not buy the "light board" type or too cheap front shade gear, which is easy to fall.

car sunSideline

The sunlight from the side window in summer is still very powerful.The effective film effect is not very ideal, and it will still be hot.Let's compare several sideways.

a. Ordinary gauze -net sideways: This type of sunshade is usually with two suction cups, or a suction cup with an middle. Its advantage is that it is more convenient to remove it, but the problem is that when the window is shaken, it may be possibleIt will touch the suction cup, especially the sidewalk with only two suction cups, which is easy to fall.

b. Static sticker side Shading: Static sticker side -type Shading is better than the yarn mesh.The unique and semi -transparent design of the mesh will never make people feel stuffy and closed.Pay attention when paste, it is best to put the lower side into the window seam for about 5cm, so that the static paste will be performed when the glass is shaken.When not in use, pull the static sticker directly, wash it with water, and roll it with Smooth paper. You can use it again in the future.

car sunRear Shading

Generally prepared for guests who are riding. Some high -end vehicles are configured with the original factories. They are telescopic and generally black mesh. This shade gear is good and beautiful and convenient.block.For those who have no sunshade after the original car, there is only one.

The Shading plate is a product placed in the windshield glass and window glass when the sun is direct.This product is to prevent direct irradiation of the internal items and interior through the car glass through the sunlight, and to reflect the sunlight to achieve the purpose of cooling down.This product wants to use the principle of reflective to reduce the temperature in the car. Is the idea good but can it be expected?

Although the principle used by the sunboard can inhibit the increase in the temperature in the car in a short period of time, after all, the environment where it is located does not change the components of the car will be heated. The temperature in the parking time will rise.Small Shading boards have changed.However, this Shading board is not completely without effect, because if there is no Shading board, the sunlight is directly shot into the car to cause the temperature of the center console in the car to rise even more than 60 degrees.The calories will be absorbed by the sunboard, and the temperature of the interior will be the same as the temperature in the car.Therefore, the excessive sunshade of the car will not alleviate the temperature rise in the car, but the Shading board will play a role in reducing the temperature rise of the interior of the car and alleviating the aging of the interior.

The difference between a sun umbrella and umbrella

1. Different weight

The umbrella rack of the Parasol will be relatively light, and some umbrella bones are non -metallic materials.The umbrella's skeleton is strong because it wants to fight against the storm.

2. Different functions

The main function of an umbrella is wind -proof and rain, and the main function of the Solar umbrella is Sun protection and ultraviolet rays to protect Skin health.

3. Different production materials and manufacturing processes

Generally, umbrella cloth design is mainly to consider waterproofing, while the Solar umbrella design is mainly on UV -proof materials, and the workmanship is fine. There are many beautiful viewing embroidery printing and dyeing design.The surface and material of the Solar umbrella are special, and the sunscreen function is particularly good. In addition, the ability to block ultraviolet rays is also very strong.After all, the umbrella is mainly based on the heat insulation function of the sun, while the umbrella is mainly waterproof.

4. Different colors

The color of the umbrella can be shallow, because it is rainy, and the color of the Parasol is generally darker, mainly anti -ultraviolet rays.

Can the Solar umbrella be used as an umbrella?

Whether the sun umbrella can be used as an umbrella. There are many sayings in the outside world, some say yes, some say it is not possible.To say, it is mainly because the Parasol is used as an umbrella that does not leak rain, but it does not work. I feel that the Parasol is specially treated. After the rain is drenched, the molecular structure will be destroyed, resulting in the sunshade of the Solar umbrella.The effect is reduced.

In fact, it is completely okay to use the umbrella once or twice as an umbrella. After using it, remember to dry the umbrella to remove it. Do not let the water molecule destroy the sunscreen coating.Remember that the Solar umbrella cannot be used to cover the rain for a long time, which reduces the "Shading" function.

However, Xiaobian recommends that the Parasol and umbrella are used separately to achieve special umbrellas and pay attention to maintenance.Because the umbrella Bone of the Parasol is lighter than the umbrella, it can't stand the rain.Especially the Solar umbrellaCoatThe layer is applied outside, so it is recommended that you do not use it as an umbrella.

What will happen when the Parasol is used as an umbrella?

1. Insufficient waterproof performance

Although the fabric of the Solar umbrella may have a certain waterproof resistance, this waterproof performance is usually not as good as a professional umbrella.In continuous rainfall, the Parasol may seep water, causing users to be wet.

2. Umbrella Bone damage

Because the original intention of the Solar umbrella is to sunscreen instead of the impact of heavy rain, its umbrella Bone may not be strong enough.Use a posterior umbrella in heavy rain, especially when it is accompanied by strong wind, the umbrella Bone may be deformed or broken.

3. Umbrella surface damage

The umbrella surface of the Solar umbrella is usually designed for sunscreen, and its material may not be wear -resistant than the umbrella surface.After using it for a long time in the rain, the umbrella surface may wear or tear.

4. Decrease in sunscreen performance

If the Solar umbrella is not dry in time after use in the rain, its sunscreen performance may be affected.The wet umbrella surface may not be able to effectively block ultraviolet rays, thereby reducing the Sun protection effect.

1. Why do greenhouse greenhouses use Shading nets

1. Over -Shading effect

The Shading net reduces the intensity of the light in the greenhouse. The larger the density specifications, the better the Shading. The same specifications are better than silver -gray Shading.

2. Cooling effect

The temperature in the shed decreased due to the coverage of the shade net, and the cooling of the surface and soil farming layer was ideal. At 10 am -at 2 am, the temperature of the upper part of the greenhouse was 37-40 C, and the temperature around the surface plants was 22-26 C. The soil was soil.The temperature is between 18 and 22 C, which is suitable for crop growth.

3. Baoyao anti -strict rain

The evaporation in the shed decreases, the soil water content is higher than the dew, and the surface soil is moist.Because the Shading net can break down the rainstorm into drizzle, the free leaves are injured by heavy rain, and the soil is not easy to end. The gap is large and the ventilation is good.

Based on the above effect of the Shading net, many greenhouse vegetable growers generally choose to cover the Shading net in the greenhouse plastic film. In this case, the Shading effect is better, which is more beneficial for crop growth.

Second, the Shading net is placed inside the greenhouse or outside

1. When the Shading net is placed outside the greenhouse, because it directly blocks the sunlight outside the greenhouse, it makes its light calories not transmitted to the inside of the greenhouse, thereby achieving a certain cooling role while covering the light, thereby playing a certain cooling role, therebyIt is also more conducive to avoiding the radiation of strong sunlight, thereby reducing the impact of high temperature on vegetable growth.

2. When the Shading net is placed inside the greenhouse, the Solar light can still enter the interior through the greenhouse film, so that the heat will also be brought in, so this method of use will not change the internal temperature, but it can cover the Solar ray of the sunlight.The impact on vegetables is suitable for vegetables that require temperature but also want to avoid ultraviolet irradiation.

Only by mastering the correct usage method and clearing the different functions produced by different use methods can we play the role of the shade net to the point, which is more conducive to the good and rapid growth of vegetables, thereby bringing a considerable economy to the growers to bring a considerable economybenefit.
