Silicone strip hardness unit

by:Kenna     2021-05-22
The hardness unit of silicone strip is one of the inconspicuous small accessories in doors and windows, but it directly affects people's living environment. Based on years of professional experience in door and window sealing products and understanding of the market and customer needs, the company has introduced advanced foreign technology to independently develop The world's advanced series of sealing products to meet domestic and international high-end customers: the pursuit of sealing will never stop, and we are also maintaining the original advantages, so that you 'must have it'! The mute contains special sound-absorbing cotton, which can effectively absorb the noise of the movable window leaking into the room. It has better sound insulation performance than ordinary sealing tape, and can improve the sound insulation performance of doors and windows by 35%. 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. Silicone strip has a hardness unit and at a high temperature of 120°C, the weather resistance of the sealing strip is still good, maintaining elastic properties, and its shape and function are not affected. Thermoplastic EPDM rubber sealing strips are often used on many luxury cars. All use this type of EPDM sealing strip, so what kind of performance does it have in actual use? First of all, it is more flexible, which is very important. Only when this point is reached, can you maintain good performance when you use it, and at the same time, it will not be achieved in long-term use. Deformed. According to the name of the installation part (component), the classification includes: engine cover sealing strip (HOOD), which can be divided into front, side and rear; door frame sealing strip (DOORSEAL); front and rear wind window sealing strip (WINDOWSCREEN); Side window sealing strip (SIDEWINDOWSEALING); sunroof sealing strip (SUNROOFSEALING); door first road sealing strip (PRIMARYDOORSEAL); window guide groove sealing strip (GLASSRUNCHANNEL); inside and outside strips (water cut) (WAISTLINE); trunk sealing strip (TRUNKSEAL) ; Anti-noise sealing strip (ANTI-NOISE); Dust-proof strip (ANTI-DUST), etc. 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. Generally speaking, the hardness unit of silicone rubber strip EPDM sealing strip can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application field continues to expand. According to the classification of vulcanization (1) Discontinuous vulcanization method (extruded After the rubber strip is cut according to a certain length, it is put into a vulcanizing tank to vulcanize, and the semi-finished product of the extruded rubber strip is put into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air Several methods such as continuous vulcanization). High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals be used? Wooden windows, aluminum clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, etc. And it does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and aesthetics of doors and windows being damaged. According to the compound structure of the rubber compound, they can be divided into pure rubber sealing strips-composed of a single type of rubber; two composite sealing strips ——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, usually The dense rubber contains a metal skeleton and reinforcing fibers. 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. Silicone strip hardness unit 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, and it also has the function of protection from external forces. However, due to the usual sun exposure, it will cause aging, shrinkage or deformation. Therefore, we have to check regularly and look at the specific gravity. If it is of good quality, the weight will be lighter. 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 talcum powder to increase the weight of the product. , So we can easily distinguish good products from inferior products by looking at the proportion when buying. 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 Variety
With new and upcoming social commerce technologies, the biggest change for rubber seal strip suppliers marketers will be a shift in focus from branding to lead generation and conversion.
