How much is a meter of silicone oil-absorbing expansion strip

by:Kenna     2021-07-07
How much is the silicone oil-absorbing expansion strip for one meter, of which the metal rubber composite sealing strip accounts for more than 60%. The cross-sectional design of the rubber sealing strip is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be designed with The same and appropriate force touches the glass from both sides of the car window glass. 3) It has an independent open-cell bubble structure. The appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed, and it can be tightly sealed with cement/sealant without burring. The bonding is integrated, adapting to changes in natural expansion and contraction, and enhancing the effect of seam sealing, expansion and water stop. 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. How much is the silicone oil-absorbing expansion strip per meter. Talking about the important role of epdm for doors and windows. With the further development of technology and the continuous improvement of living standards, and the call of an energy-saving and harmonious society that has been advocated, we all know that doors and windows are buildings. Eyes, its energy loss can account for 40% of the total energy loss in buildings, which has attracted enough attention, especially in large cities like the capital Beijing in 2004 to reduce the heat transfer coefficient of doors and windows (indices for thermal insulation and energy saving) As a mandatory acceptance index, it has also attracted great attention and implementation in various provinces, cities and regions across the country. Energy-saving doors and windows have become the mainstream of building doors and windows. Silicone sealing strips can also be glued to materials with smooth surfaces because of its high shock resistance and waterproof performance. According to the composite structure of rubber materials, automotive sealing strips can be divided into pure rubber sealing strips-composed of a single type of rubber; 2. Composite sealing strip-composed of dense rubber and foam sponge rubber, often containing a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strip-composed of two types of dense rubber (one of which is light-colored) and sponge rubber The composition usually contains a metal skeleton and reinforcing fibers inside the compact glue. This technology is recognized by the world as a good process method for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also distributes it uniformly, which is beneficial Improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: Hot air sulfur has developed to strong wind type vulcanization, that is, high temperature, high speed hot air vulcanization (Tmax: 450°C and Vmax: 60m/s) is also used. The effect of flame pretreatment can be achieved, and the safety is greatly improved. 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. Silicone oil-absorbing expansion strips can achieve green and energy-saving building with good air-tightness and water-tightness, prevent heat conduction, and realize the energy-saving and thermal insulation function of warm in winter and cool in summer. Coated sealing strip keeps you away The hustle and bustle of the world will give you a quiet and comfortable life. Here, we have covered sealing strips, which can meet the needs of people of all ages. From the moment you are born, it will accompany you throughout your life! Choosing a covered seal, choosing a quiet life, happiness is so simple! . 'Specialization' originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. The sound insulation, heat preservation, sealing, impact resistance and environmental protection characteristics of the coated sealing strip have been more and more Many consumers pay attention to 'functionality'. For a long time, German design has always been a well-functioning, rational and reliable image, especially the harmony and unity of the entire product in terms of technology, function, logic and sense of order. The sealing strip structure makes the door leaf and the door sleeve tight and seamless, has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. Material: 1. Made of high-quality EPDM rubber, foaming process , 2. The back adopts imported double-sided tape, and the interlayer is grid-shaped glass fiber. The scope of application and installation method: 1. The electrical cabinet sealing strip is made of good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and wide The use temperature range (-40℃~+120℃) of EPDM rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which are strong and durable. 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, which It is characterized in that, in terms of weight ratio, the automobile product rubber is 100 for EPDM rubber, 90 for carbon black, 20 for softening oil, 15 for processing aid, and 5 for accelerator.
