Silicone Strip Extruder Company

by:Kenna     2021-06-05
Silicone strip extruder company, the auxiliary seal of the compensation ring is a metal bellows, called a bellows mechanical seal, 2. The composition of the mechanical seal: mainly includes the following four types of components, a. The main seals: moving ring and static ring, b. Auxiliary seal: sealing ring, c, compression: 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 change. It feels very stiff, easy to break, and the physical properties of the silicone rubber seal have no change. 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. Among the silicone strip extruder companies, classification according to the title of the device part (component) is a common way, which includes the engine room sealing strip, the front and rear wind window sealing strip, the door frame sealing strip, the door sealing strip, the door glass guide groove sealing strip, Dust-proof strips on the lower part of the door, internal and external sealing strips for door and window sills, side window sealing strips, sunroof sealing strips, roof cover sealing strips, trunk (luggage) sealing strips, etc. Installation method: self-contained double-sided tape, just stick it directly (The paste surface must be smooth, clean, smooth and dry). Uses are mainly used in the door frame, side windows, front and rear windshield, engine cover and trunk cover, which play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes three Ethylene propylene rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance performance, has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use. It is between -50 degrees and 120 degrees. It can maintain its original high sealing performance. 8℃, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and it is generally a dark-colored product. Application range: Use temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings It is recognized by the domestic door and window industry for its wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, relatively high density, and generally black products. 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. According to the sealing characteristics of silicone strip extruder company, automobile sealing strips can be classified into weather sealing strips (WEATHERSTRIP) and general sealing strips (SEALING). Among them, weather sealing strips have hollow sponge foam tubes, which have better temperature and humidity retention. The function includes the following items in the usual maintenance process. First, the detergent must be cleaned. After the cleaning is not done, it is also necessary to apply a layer of protective agent to prevent aging and prevent dust. Fourth, the impact resistance is good. Many people want to use foam sealing strips as cushioning materials, because the impact resistance of this product is very good, the physiological stability of the rubber sealing strips is very good, and the resistance to deformation is also very good. It is strong, not only resistant to ozone but also resistant to ultraviolet rays, so this product has been widely used, and it is inseparable from many places such as medical diversion, electronics, wire and cable, etc. , This product also has a very good advantage, that is, long service life. Energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, as well as several major modules of processing technology. The sealing strips are relatively low cost due to their proportion and are affected by some traditional concepts that do not pay attention to energy-saving standards for doors and windows. , Has been ignored by many door and window manufacturers, but we can’t help but admit that the sealing strip plays a vital role in the door and window system. What important role can EPDM sealing strip play in the door and window system? . Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators. 2. The automobile product rubber according to claim 1, wherein the automobile product rubber is calculated by weight ratio, the EPDM rubber is 100, the carbon black is 90, the softening oil is 20, and the processing aid is 15 , The accelerator is 5. 3. A preparation method of automobile product rubber formula, which is characterized in that it comprises the following steps: step one, put the EPDM rubber into the internal mixer, and the mixing temperature is controlled below 80 ℃ Mix for 2 minutes;
Anyone who has seen the latest custom sealing strip rubber seal strip suppliers in operation cannot help but be impressed with how far the technology has progressed over the past few years.
