Silicone strip slotting standard

by:Kenna     2021-06-09
Silicone strip slotting standard, if the smell is very big, it is not a regular PVC. The sealing strip is a frequently used product, which is made according to a special process and special materials. The function of the sealing strip is to play The function of sealing, which can effectively protect the performance of utensils, is an indispensable part of many products. It can be said that it is indispensable and has played a great role. We cannot ignore it. Another point is It does not absorb water, so it is also a material that replaces traditional asphalt. It is not because of its water resistance that it will not be saturated under high water pressure. Another point is that it is more environmentally friendly on the entire material. Will not cause any harm to the human body. 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 silicone strip is slotted standard and also has good dustproof, sound insulation and decorative effects. It also protects the car body and effectively improves the comfort of the ride. The characteristics of the car sealing strip are resistant to low temperature at -40°C. In the middle, the sealant strip does not become hard and brittle, it still maintains softness and good adhesion of the strip, showing excellent cold resistance. The performance characteristics of the EPDM seal strip: excellent overall performance and outstanding ozone resistance , Excellent weather resistance, good high temperature and low temperature performance, outstanding chemical resistance, resistance to a variety of polar solutes, and low relative density. '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, blocking sound penetration stronger, and has strong resilience, sound insulation and environmental protection. The skeleton sealing strip is made of dense rubber, foamed rubber and steel wire/steel sheet Co-extruded. Also known as EPDM (EPDM)-suitable for special environments from -40°C to +160°C, with superior ozone resistance, UV resistance, chemical solvent resistance, and various The physical and chemical performance indicators are far beyond similar products. For this reason, the standard of GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early to regulate the production and inspection of sealing strips. However, the current building materials market The quality and price of rubber and plastic sealing strips for upper doors and windows are very confusing. Four composite sealing strips-our company took the lead in developing and producing composite sealing strips composed of 4 kinds of rubber materials in China. The surface is covered with a thin protective layer of glue to further increase the service life of the seal. '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 sealing strip have attracted more and more consumers' attention. 'Functionality' has long been a functional, rational and reliable image of German design. , Especially the harmony and unity of the whole product in terms of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door sleeve tight and seamless, blocking sound penetration, and has strong resilience. , Sound insulation and environmental protection. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 22 hours, deformation rate ≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate ≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Thermal conductivity K value test: K value ≤ 0 at 0°C. It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, physical, and physical properties of different application fields developed and designed by our company The special performance can meet the application needs. The installation method of the inlaid wooden door sealing strip: because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, usually 4mm, 3mm, 2.5mm There are several types of 2.0mm, and most of them are 3mm. You must be optimistic about using them when purchasing sealing strips. In addition, the specific gravity of this type of product (above 1, 4) is equivalent to that of PVC (low-end vulcanizate The proportion of EPDM rubber strips is larger) 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. Sealing strips can be based on several methods such as section shape, vulcanization method, use location and purpose, and materials Classification, product characteristics 1) Light bulk density, high expansion and contraction strength, no water absorption (replacement of traditional three-oil four-felt, asphalt wood cedar board and other materials). It is a kind of use of the characteristics of certain materials to make pores appear in the interior through processing The sealing strips are divided into EPDM foam sealing strips, silicone foam sealing strips, and PU foam sealing strips.
