One-line operation system of electrostatic silica gel

by:Kenna     2021-03-12
One-line operation system of electrostatic silica gel. Doors and windows bring light and vitality to the room. Doors and windows extend the limited space infinitely. Said ternary bc sealing strip (rubber EPDM)-suitable for the special temperature of -40℃-+160℃ Environment, with superior anti-ozone characteristics, purple light reflection characteristics and chemical solvent resistance characteristics, far beyond similar products, widely used in vehicle seals and building seals, in addition to various physical and chemical performance indicators in the field, our company's development and design are different The hardy and heat used in the field and send foam and solid, with special properties that can meet the needs of the application. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. According to the cross-sectional shape, the electrostatic silica gel one-line operation system can be classified into solid core products (round, square, flat cross-sectional shapes), hollow products, and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. The cross-section design is very important for the rubber sealing strip. The first is the shape and size design of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force, and are classified according to the sealing characteristics. , Can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car shelter from wind, rain, dust and heat by maintaining it. , Sound insulation effect, and when the body is shaken and distorted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. In addition, the material proportion of this type of product (above 1, 4) is comparable to that of PVC (low-end vulcanized EPDM rubber strips have a greater proportion). The window rate is similar to that of PVC rubber strips, and the cost of use is relatively high, which is difficult for door and window companies to accept , The sealing strip can be classified according to several methods such as cross-section shape, vulcanization method, use part and purpose, use material, etc. Product characteristics 1) Light bulk density, strong expansion and contraction strength, non-absorbent (replacement of traditional three-oil four-feet, asphalt wood fir Board and other materials). Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. The length and thickness of the lip of the electrostatic silica gel running system in one line should be appropriate. Too thick or too long will make the glass lifting resistance too large. Too thin or too short will cause the glass to not be well guided and sealed, resulting in vibration, noise, Rain leakage; second is the shape and size design of the bottom of the section. There are protrusions on the section of the window steel channel, which is used to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can Use the elasticity of the sealing strip itself to attach to the steel guide groove to prevent it from falling out; it is the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely attached to the car body. Second, high heat insulation. In the process of use, it has good heat insulation, which greatly reduces the thermal conductivity. Therefore, the heat insulation of this product is very good, which can effectively prevent the loss of temperature. , Third, the automobile industry The demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are required to be used, such as the sealing of windshields and automobile windows, as well as the outer skin of high-voltage lines. There are many places such as spark plug protection covers. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass, 3) It has an independent open-cell bubble structure, and the appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion. The shrinkage changes and changes to enhance the sealing, expansion, and water-stop effect of the joint.
Every day of the year, there is some city or town in the world that is changing over to for custom sealing strip.
