In spring, there is a lot of wind and sand, and in summer, there is more rain. The most useful thing at this time is glass. After all, if the front windshield is vague, it will affect our driving safety. Today, we will come and talk to you about glassy water. Then, what is the so-called glass of water? Automobile windshield glass commonly known as water (ie, window glass cleaning fluid, wiper water), is the maintenance of the car's largest consumables. In general, glass water on the retail market of our country can be divided into three types: one commonly used in summer, adding the shellac in the cleaning solution, which can quickly remove the flying insects that hit the windshield; This type of anti-freezing glass cleaning fluid designed for winter use guarantees that when the outside temperature is below -20°C, it will not freeze and freeze the car facilities; a type of special effect antifreeze type guarantees that no ice will remain at -40°C. It is suitable for use in the coldest areas in the northernmost part of China. In southern China, the first type of glass water can be used. Why is glass water blue? In automotive glass water, many functions are accomplished through the addition of chemical additives. Therefore, glass water is toxic, and the liquid is colored blue to remind people of its toxicity. At the same time, avoid adding errors in order to distinguish them from other colored liquids. Glass Water Composition and Function High-quality automotive windshield glass water mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors and a variety of surfactants. Automobile windshield glass water is commonly called glass water and mainly has the following functions: 1. Cleaning performance: It is composed of a variety of surfactants and additives. Surfactants usually have wetting, penetration, solubilization and other functions, which play a role in cleaning and decontamination. 2. Anti-freeze performance: With the presence of alcohol and ethylene glycol, it can significantly reduce the freezing point of the liquid, thus acting as an antifreeze, and can quickly dissolve the frost. 3. Anti-fog properties: A layer of monomolecular protective layer will be formed on the glass surface. This layer of protective film can prevent the formation of droplets, ensure the clear and transparent windshield, clear vision. 4. Anti-static properties: After cleaning, the substances adsorbed on the glass surface can eliminate the charge on the glass surface and anti-static properties. 5. Lubrication performance: Contains ethylene glycol, which has a high viscosity and can act as a lubricant to reduce the friction between the wiper and the glass and prevent scratches. 6. Anti-corrosion performance: contains a variety of corrosion inhibitors, without any corrosive effect on various metals, automotive finishes, rubber, absolutely safe. Some owners will give up buying a bottle of special glass water for about 10 to 20 yuan, and choose "remedies" - homemade glass water. They use detergent, detergent, washing powder, etc. to replace special glass water with a bit of water. They think that it is cheap and easy; some owners directly replace glass water with fresh water. There are certain hidden dangers in these practices. Water against washing powder: There will be some sediment in the washing powder water, and for a long time, it will not only corrode the rubber tube, but also will block the water outlet, and in severe cases it will damage the motor. General detergents are alkaline, there will be a certain degree of corrosion of rubber, will accelerate the hardening of the catalytic wiper strip, when the hardened strip scratches the windshield, it will speed up the windshield surface is scratched, scratched. If the wiper is replaced again, the cost will be several ten times that of glassy water. "Jin Yuankang three alloy electroplating technology refers to the double plating covering three element alloy thin, of which three yuan alloy copper tin Zinc Alloy" refers to the "three element alloy and stainless steel similar appearance". The coefficient of resistance is 1.7 cm (RF-10 GHz), the conductivity of (106S/m) (RF-10 GHz), the contact resistance is less than 10m at cN 100, with the help of a number of micro active flux solderability. Jin Yuankang ternary alloy electroplating for high frequency connection, in a wide frequency range the maximum transfer rate requirements, in addition, the "Three Element Alloy Plating technology can make the RF devices in industrial gases, perspiration and other corrosion or scratch, keep good appearance, without the protection of the silver coating even in normal circumstances rapid oxidation. "Three alloy plating technology" combines the excellent electrical conductivity of silver and the corrosion resistance of the alloy with "three elements", and the thin coating of the alloy with the value of in the range of 10GHz does not affect the good conductivity of silver. "Three alloy plating technology" does not contain magnetic elements, "plating alloy technology of three yuan" to prevent surface oxidation and film, the use of the surface will not lose luster. The characteristics of three element alloy plating surface to prevent scratches, not sensitive to damage, but also to prevent the silver plated cold welding and assembling with good damage caused by non. Compared with the silver plating, the "three element alloy technology" in the assembly of the device is especially to reduce the loss caused by the collision.
