Silicone foam strip use

by:Kenna     2021-07-12
Silicone foam strips are mainly used for door leaf door frames, side windows, front and rear windshields, engine covers and trunk covers, which play a role in waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes EPDM rubber sealing strips have excellent anti-aging, high and low temperature resistance and chemical resistance performance, good elasticity and compression deformation resistance, and will not crack or deform after long-term use. The original high sealing performance can be maintained between 50 degrees and 120 degrees. 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. Silicone foam strip is durable and maintains stable performance and long service life in different environments, anti-aging, wear-resistant, non-wrinkle, non-stretching, non-stick paint surface, and is not affected by high temperature and dust , Non-mildew and anti-ultraviolet and ozone erosion. Our value to you starts from your experience. It is durable and new forever. It is the real experience of users. The beautiful covered PU sealing strip is green and environmentally friendly, and it is stylishly sealed; a perfect solution The contradiction between sealing and sound insulation realizes the dual effect of sealing and sound insulation; doors and windows are perfectly matched with products. 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 contact the glass. Check regularly for cracks and breaks. If you find that the sealing strip is broken, you can find an adhesive to repair it. The adhesive here is for special use. It is bonded so that it is not difficult to repair the cracks. Talking about the important role of epdm for doors and windows. With the further development of science and technology and the continuous improvement of living standards, and the call of an energy-saving harmonious society that has been advocated, we all know that doors and windows are the eyes of the building, and its energy loss can be It accounts for 40% of the total energy loss of buildings, which has attracted enough attention, especially in large cities like the capital Beijing. In 2004, the heat transfer coefficient of doors and windows (indices for heat preservation and energy saving) was used as a mandatory acceptance index. Provinces, cities and regions across the country have also attracted great attention and implementation, and energy-saving doors and windows have become the mainstream of building doors and windows. 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.

Ensure personal safety. The auxiliary seal of the compensation ring of the silicone foam strip is a metal bellows called a bellows mechanical seal. 2. The composition of the mechanical seal: mainly includes the following four types of parts, a. The main seals: moving and static rings, b, Auxiliary seals: sealing ring, c, compression parts: spring, push ring, d, three. At the same time, put the PVC sealing strip and the silicone rubber sealing strip in the freezer compartment of the refrigerator. After a few hours, the PVC sealing strip will become feel It is very stiff, easy to break, and the physical properties of the silicone rubber sealing strip have not changed. Sealing strip is a product that seals something so that it is not easy to open, and plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dustproof, and fixing. EPDM rubber strip adopts microwave vulcanization process One-time molding, smooth and beautiful surface, good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance, and a wide temperature range (-50℃~+150℃). It has been used in automobile doors and windows. Widely used in manufacturing industries such as curtain walls. my country's automobile door sealing strip is one of the important parts of automobiles, and it is one of the important parts that determine the quality of the automobile. What are its more important roles in the automobile, foam sealing strip 1, The basic concept of the mechanical seal: the mechanical seal refers to the prevention of fluid by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid from sliding. Leaking device.
