Windshield glass can determine whether the driver's line of sight is clear or not. In summer and winter, because of the complex climate conditions, the windshield glass is easy to appear mirror blurred or mirrored reflector and other problems. Drivers can easily confuse their line of sight and affect the safety of driving under the condition of bad weather at night or weather. In the summer, when the rain is much more, the surface of the glass will leave a lot of shellac or the traces left by the rain. In winter, some rain and snow weather can easily make the mirror frosting. These problems seem simple, but it is not easy to deal with them. 1. There are a wide variety of glass water available on the domestic market, but it is mainly divided into three kinds: glass water in summer, glass water of antifreeze in winter and special antifreeze type glass water. The glass water used in summer is mainly used to remove the flying insect residue on the mirror, and the winter antifreeze glass water is mainly to ensure that the automobile parts will not be frozen when the temperature is below zero below 20 degrees C, and the special antifreeze glass water is mainly used in the northern especially cold areas, and it can ensure that the car is still unfrozen at minus 40 degrees C. In the regular glass process, we choose the suitable glass water according to the season and the weather conditions. When we find the windshield glass surface is blurred, it will be much brighter with the suitable glass water. At night, the problem of glassy reflection of glass can also be cleaned with glass water. In addition, when running high speed or dusty, glass water will be used very quickly, and we should also pay attention to inject new glass water immediately. Some owners think that cleaning glass is only clean and decontamination, so the use of detergent or detergent instead of glass water, some car owners are more cheap, direct use of water instead, these are hidden. There are some precipitates in chemical detergents such as washing powder, which are easy to corrode rubber tubes for a long time, and will clog the nozzle. In severe cases, the motor will be damaged. And the general detergent will continue to corrode rubber tubes to accelerate the hardening of the rubber strip of the catalytic wiper, and when the hardened adhesive strips scrape the windshield, the surface of the windshield will be shaved and scraped. If the wiper is rereplaced, the cost will be several times the price of glass water. Although ordinary water is clean, there are also many chemical residues in it, which will cause blockage of the nozzle and affect the water spray. Long term use also increases the friction of the mirror surface, making it easy for the wiper to leave a slight scratch on the mirror. 2, the car sticker that matter in the summer, a thin layer of heat insulation film can play a major role, not only to resist hot and hot sun, but also heat insulation, anti ultraviolet. Industry insiders pointed out that the heat insulation effect is one of the important reasons for the consumers to choose the sticker, in addition, the transmittance of the heat insulation film and the anti ultraviolet index are all the contents that the consumers must care about. However, many consumers have many misconceptions about the insulation film. There are front and rear windshield and side windshield membrane for automotive insulation film. Among them, the front windshield is the highest requirement for insulation film. According to the regulations of the Ministry of public security on traffic safety, the transmittance of the front windshield must be greater than 70%, so that the driving safety will not be affected. The front windshield is the most taboo to stick to the dark heat insulation film. In addition, the higher the UV index is, the better it will be, because it can protect the central console and prevent premature solar aging. The side windshield insulation film is also based on the premise that the rear view mirror is not affected by the vehicle owner. The choice of the side windshield is more flexible and the color is changeable. For example, some car owners like blue heat insulation film and so on. In addition, the heat insulation effect of the thermal insulation film is not directly related to the depth of the color. The coating process in the heat insulation film is the key factor to determine the heat insulation effect. The higher the heat insulation is, the more reflective the film is. Generally speaking, the insulation film on the market with a heat insulation rate of 60% is already a good product. If the product itself claims to have a product of up to 80% or even 90% insulation, consumers will have more than one mind. If the vehicle is equipped with GPS navigator, the owner should choose non-metallic film products, because most of the explosion-proof film on the market still belongs to the metal film at present, and it does cause interference to the GPS signal. 3, to the love car glass risk glass separate risk, that is, the insurance company is responsible for the insurance in the use of insurance in the process of use of the car glass broken loss of a commercial insurance. Broken glass alone means that only the windshield and window glass (excluding car lights and mirror glass) are damaged. In addition, if you are insured in accordance with the imported glass rate, the insurance company is compensated according to the price of the imported glass. If the domestic glass rate is selected, the insurance company will pay the price of the domestic glass. To buy glass insurance for a car is an effective way to ensure the safety of the glass. The owner can also drive safely.
