Is the silicone tape smelly?

Is the silicone rubber strip smelly? Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a certain gap, which causes the door and window departments to close tightly. The door and window sealing strips are used to eliminate these gaps. However, there are many types of door and window sealing strips, and their uses are also different. I have compiled some relevant information about the types of door and window sealing strips for everyone here. Door and window sealing strips can be divided into major categories in use: glass sealing strips, door leaf and door cover sealing strips and wool strips. The glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the door frame, and the wool strip is mainly used to seal the gap between the frame and the door. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. At a high temperature of 120℃, 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 in many luxury cars. Type of EPDM sealing strip, 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. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties. 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also called vulcanization bed vulcanization, heating medium For the middle 0. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use, the performance advantages of the coated sealing strip? 1. Compression deformation test: 50% at 70℃ Compression rate continuous compression for 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℃ No significant change in sealing performance 4. Heat conduction K value test: K value ≤ 0 at 0℃. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements for materials. First of all, it must have strong stretching ability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip must match the door and window profile, which is generally applicable Used on hanging windows and folding doors and windows. The wool strips are usually installed on the sashes of push-position doors and windows to seal the gap between the frame and the sash. The specifications of the wool strips can greatly affect the watertight performance of the doors and windows, and at the same time It will also affect the opening and closing of doors and windows. If the specifications of the tops are too large, or the vertical hairs are too high, it will be very difficult to assemble, and after assembly, the resistance of the doors and windows will increase when they move. If the specification is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the sealing performance of the door and window. There are generally two types of tops that have been silicified and those that have not been silicified. Generally, the effect of treatment will be Good point. Quality tops have the following characteristics: no obvious defects in appearance, straight surface, bottom plate and vertical hair are relatively smooth, no bending phenomenon, and there are no pitting and other problems on the bottom plate, which meets the size requirements. Silicone glue Is the strip smelly? Silicone sealing strips can also be glued to smooth surface materials because of its high shock resistance and waterproof performance. According to the compound structure of the rubber material, car sealing strips can be divided into pure rubber sealing strips-composed of a single glue Two kinds of composition; 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 strips-composed of two dense rubbers (one of which is light-colored ) And sponge glue, usually containing a metal skeleton and reinforcing fibers inside the compact glue. These advantages are irreplaceable by other materials such as PVC. It can meet the needs of design and use for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. Automobile sealing strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extrusion head has a single head, a composite (double composite and multiple composite) head and a shear head. , The screw length to diameter ratio of the microwave vulcanizing extruder is generally 16, and the screw length to diameter ratio of the shear head vulcanizing extruder is greater than 20.
