Silicone bendable water retaining strip height

by:Kenna     2021-07-08
Silicone can bend the water retaining strip height. These advantages are irreplaceable by other materials such as PVC. It is suitable for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. It can meet the needs of design and use. Automobile sealing strip production process 1. Extruding rubber sealing strips for automobiles is extruded by a cold feed extruder. The extruder head has a single head and a composite (double composite and multiple composite) machine. The screw length to diameter ratio of the microwave vulcanizing extruder is generally 16, and the screw length to diameter ratio of the shearing head vulcanizing extruder is greater than 20. Introduction to electrical cabinet door self-adhesive sealing strips are made of three types of self-adhesive sealing strips with good elasticity and resistance to compression deformation, resistance to aging, ozone, and chemical effects, and a wide operating temperature range (-40°C to +120°C). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which is strong and durable. It plays a key role in various electrical cabinets. The height of the silicone flexible water retaining strip is classified according to the title of the device part (component). It includes the engine room sealing strip, the front and rear wind window sealing strip, the door frame sealing strip, the door sealing strip, and the door glass guide groove sealing strip. , Dust-proof strips on the lower part of the door, internal and external sealing strips of the 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 adhesive, directly paste it Yes (the surface must be smooth, clean, smooth and dry). 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 larger 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 section shape, vulcanization method, use part and purpose, use material, etc. Product characteristics 1) Light bulk density, strong expansion and contraction strength, non-absorbent (replace the traditional three oil four felt, asphalt wood fir Board and other materials). The skeleton sealing strip is co-extruded from dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for the special environment of -40℃ -+160℃, it has superior anti-ozone characteristics, anti-ultraviolet characteristics, resistance to chemical solvents, and various physical and chemical performance indicators far exceed Similar products. Silicone bendable water-retaining strip height sealing strip is a very important part in doors and windows. It can not only ensure the watertightness of doors and windows, but also reduce sound insulation. At the same time, it can also be protected by external forces. However, due to the usual sun exposure, it will cause aging, shrinkage or The phenomenon of deformation, therefore, we need to check regularly and look at the specific gravity. If it is of good quality, the weight will be light, if it is a defective product, the weight will be heavier. This is because regular manufacturers use calcium carbonate as a filler and some manufacturers use talc to increase it. The weight of the product, so we can easily distinguish good products from inferior products by looking at the specific gravity when buying. , The weight of the lightweight foam sealing strip is very light, which brings great convenience to the transportation and use process, and the product's strength and toughness are also very good. It can be used in any environment and can be used at very high temperatures. Working for a long time in a high and low temperature environment, these advantages have expanded the application range of the product. Then, what are the main application areas? 1. Modern industry and defense industry are not only very common in life, but also can be used in modern industry and defense industry to help companies produce products. 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. It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, solid, and special properties of different application fields developed and designed by our company can meet the application needs. Installation method of inlaid wooden door sealing strip :Because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, there are usually 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm, which is used in the purchase of seals. Be optimistic about the article.
