[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.

car sundevelop

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?

top ten brands of building Shading & gt; & gt;

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.

Shading coefficient is good or good

The smaller the sunshade coefficient, the better the performance of the sunlight to the indoor radiation.As the state's requirements for building energy conservation are getting higher and higher, as far as the requirements of building glass are concerned, the most important is the Shading (sung) coefficient SC (or SE) and the heat transfer coefficient K value (or U value).The hid coefficient of ordinary glass is about 0.9, so the glass should be processed on the surface, such as thermal reflex glass, low -radiation glass, etc., thereby reducing the shade coefficient.

glass shade coefficient concept description

1. The shade coefficient includes not only the sunlight (300nm-2500nm spectrum) penetrating the glass into the room, but also the energy of the secondary heat transfer of the glass.EssenceThe glass of the glass will absorb the energy of some sunlight, and its own temperature rises. At this time, the glass will be transferred to the room for the second time through radiation and convection.If there is a piece of tea -colored glass, the direct transmission ratio is 50%, and the total transmission ratio of the Solar light is 63%. So 13%of the amount of the glass is the secondary radiation after the glass absorption.

3. The value of the solar energy of the standard 3mm white glass is called the direction ratio, and the value of my country is 0.889, and the international is 0.87. It seems that this difference is not very large, but when it is involved in foreign construction projects involved There should be consensus.Example Calculate the shade coefficient SC = solar energy thermal coefficient (SHGC)/route ratio.When the SHGC is 0.818, the domestic calculation value is 0.92, while the overseas calculation results are 0.94.

3. The sunshade coefficient detects the full spectral energy of the Solar radiation, including ultraviolet light, visible light and near -infrared light in the 300nm ~ 2500nm band. These light shots can produce calories when entering the room.The smaller the sunshade coefficient, the less sunlight entering the room, the smaller the calories that can produce.Low shade coefficient does not directly mean that the visible light transmission rate is also low, because when maintaining the visible light transmission rate, reducing the transmission of near infrared can also reduce the shade coefficient.

4. The shade coefficient is a proportional value of a 3nm transparent glass, which does not mean that the sunlight of the sample glass is always transmitted.For example, when the shade coefficient of the glass is 0.5, it cannot be considered that this piece of glass can enable 50%of Solar radiation heat to enter the room. It should be understood that the Solar calories that the glass can pass through is 50%of the standard 3nm white glass.When the sunshade coefficient of the glass is 1, it means that the total direction ratio of the sunlight of this sample is equal to the standard 3nm white glass.When the shade coefficient is 0, it means that the sample cannot be directly passed through the Solar light through the sun, nor can it be transferred to the solar energy.

5. The heat controlled by the shade coefficient is not the same as the heat control of the heat transfer coefficient. The latter refers to the heat transfer caused by the temperature difference. The former is mainly aimed at Solar radiation.

1. What umbrella is the garden umbrella

The courtyard umbrella is also called the side umbrella, which is mainly used for large parasols that are directly illuminated by sunlight.At the beginning of the design, it was mainly used for Shading of the aristocratic courtyard, and all the name was as a result.According to the shape, courtyard umbrellas can be divided into pillar umbrellas, Roman umbrellas, banana umbrellas, and aluminum alloy mid -column umbrellas.There are two types: circular and Square.Suitable for various leisure venues, cafes, villa gardens, terrace, tea sitting, lawn, Outdoor, beach, bar street, commercial street, gatekeeper property, lake fishing, friend gathering barbecue, the best shade, tourism supplies, it, itIt is the ideal choice for your leisure and Shading, and you can also become a beautiful landscape for your bright house.

2. How to choose Outdoor courtyard umbrellas

There are three technical means to prevent ultraviolet rays: one is to mix ceramic particles when fabric textiles are mixed with ultraviolet rays to achieve the effect of anti -ultraviolet rays.The second is to fit the ultraviolet isolation agent to the fabric without changing the feel and appearance of the fabric itself.However, different fabrics themselves will restrict the use of this absorbent -proof ultraviolet function.Therefore, when choosing Outdoor garden umbrellas, you can judge the level of anti -ultraviolet performance from three aspects.

1. Pay attention to the anti -ultraviolet performance of the fabric fiber itself

Experiments have shown that in the non -processed fiber, the best resistance to ultraviolet anti -ultraviolet rays of polyester fibers is the best. The benzene ring in the polyester fiber molecular structure has the effect of absorbing ultraviolet rays. nylon in chemical fibers is also the artificial cotton and artificial artificial cotton in nylon glue.silk, etc., anti -ultraviolet performance is not as good as polyester.Therefore, we should try to choose as much as the ultraviolet umbrella with polyester fiber as the raw material.

2. Pay attention to the organizational structure of the fabric

The thickness and tightness of the fabric have a certain impact on its anti -ultraviolet performance.The thicker the fabric, the better the anti -ultraviolet performance, and the closer the fabric, the stronger the light power, the smaller the ultraviolet rays through.

In addition, it is necessary to pay attention to the color of the fabric. According to the test results of the Chinese Institute of Metrology, the darker the color of the fabric, the smaller the ultraviolet transmission rate, and the better the anti -ultraviolet performance.

Therefore, when we choose the Parasol, we must fully consider the thickness, tightness and color of the fabric.No matter what brand it is, it is only necessary to comply with the above selection method.

3. The price is not proportional to the effect of anti -ultraviolet rays

The price of an umbrella is not simply determined by the quality of the anti -ultraviolet effect.According to reports, some umbrellas are high in price, which is related to the fabrics, handles, accessories, umbrella frame materials, production technology, packaging and its brand effects. The effect of anti -ultraviolet rays is not the main factor of pricing.

1. color lanterns

color lamp art is the comprehensive decorative art of the lamp.In ancient times, its main role was lighting. Paper or silk was used as the lantern Skin. The skeleton was usually made of bamboo or wooden bars. Put candles or light bulbs in the middle to become a lighting Tool.

There are many small bulbs on each color lamp, but each color lamp has only one external connector. Generally, it is required to connect220VOn the lighting circuit, the color lamp is connected in parallel in the circuit.That is, a line is a fire line, a line is a zero line, and then colorful Lights are on the street.Like a Light bulb at home, each one is accessing220VIn the circuit.

Second, candle

In literary and artistic works, candles have the symbolic meaning of sacrifice and dedication, which can add romantic atmosphere to the room.

Three, aromatherapy

1Most of the aromatherapy essential oils are refined from the fruit, flowers, leaves, leaves, roots or seeds of the plant. It has antibacterial, sterilization, detoxification and other effects. It can reduce the amount of bacteria in the air for about half an hour.

2It can purify air, improve air quality, and shape no pollution human survival space.

3It can promote metabolism, reduce fatigue, and help maintain respiratory skills.

4, Adjustable physiological functions, beauty and beauty, soothing mental stress, promoting spiritual spirit, and improving work efficiency.

5The aromatherapy can create a Romantic atmosphere, romantic aphrodisiac, and promote lust.

Fourth, process ornament

Putting a incense burner ornament in the living room or study room is also very Zen's artistic conception. The cute and cute Rulai Buddha not only beautifies the home environment, and has a high -level enjoyment with visual and smell.ceramics are retro, strong and environmentally friendly materials, which look retro and noble, round and Smooth, and the symbol of high aspirations. The details are very realistic and the craftsmanship is particularly good.

5. Creative table

1""mateo"Rural desk is an excellent supplement to any space, and it has a more simple, industrial or rural flavor. It is also a style suitable for any size space.

2, glass bed

3, The amethyst table, the expressive geographical design

Six, table lamps

The desk lamp is mainly decorative, which is convenient for reading, studying and working.The table lamp has far surpassed the value of the table lamp itself, and the table lamp has become a artwork.Under the concept of light decoration and heavy decoration, the decoration function of the table lamp is even more obvious.In addition to reading and decoration.The latest technology is also like robots. It can move, dance, automatically adjusts, play music, clocks, videos, touch and other functions, especially the ceramic technology table lamp also has the value of collection.What role does lighting play in home life?In the night, the light is an elf, and it is the creative expert of a warm atmosphere.Through the level of light and shadow, the space is more vital; during the day, the lamps are turned into the decoration art of the living room. It is dotted with furniture, fabric, and decorations.

Seven, small speakers
