Performance characteristics of different rubber sealing strips

We know that rubber sealing strip is an indispensable sealing product in our life and production. With it, we don't have to worry about where the air leaks, where the water leaks, where the air leaks and so on. So such an important thing because the material does not have to have different characteristics, the following we introduce one by one. Natural rubber sealing strip: the applicable temperature is -50~120 ℃; it is characterized by good elasticity and low temperature performance, but poor high temperature performance, poor oil resistance, and easy aging in the air. Styrene butadiene rubber sealing strip: the applicable temperature is -30~120 ℃; it is characterized by animal and vegetable oil resistance, which is large for general mineral oil expansion, strong aging resistance, and better wear resistance than natural rubber sealing strip.

Test index of silicone foam round tube

Silicone foaming round tube is a kind of high temperature resistant silicone foaming extrusion products. The products are made of 100% gas phase silicone raw materials added with foaming agent and vulcanized by high temperature baking oven. During the vulcanization process, a lot of air occurs, resulting in many small holes inside the silicone. The biggest feature of the product is high temperature resistance and good elasticity, which can be continuously operated at a high temperature of 300 degrees without sudden changes.

Is the car sealing strip useful? Can it sound insulation and noise reduction

The main function of the automobile sealing strip is to prevent dust and odor. As for the sound insulation and noise reduction, the effect is minimal and basically negligible. The noise isolation of automobiles is a systematic project, which does not mean that the increase of sealing strips can be completely solved. Vehicle noise mainly comes from tire noise, wind noise and engine noise. None of these three noises can be solved by installing sealing strips. Therefore, it can be said that the so-called car sealing strips on the Internet are an "IQ tax". Secondly, the inferior sealing strip is easy to age after exposure to the sun, and then directly stick to the paint surface, which will cause certain damage to the paint surface of the car.

The surface and gaps shall be filled flush with putty. ② Clean the gap of the cover panel. ③ Brush all screw caps with anti-rust paint. ① Putty: Use caulking plaster to fill and scrape the board joints. Seal seams with perforated paper tape and lightly cover with caulking plaster. ② The second putty: lightly wipe the board surface and trim the edge, the width is 180mm, and cover the screw again. Third putty: apply a layer of caulking gypsum putty, the width of about 270mm surface putty after solidification, with #360 sandpaper polishing. ① Full putty scraping and polishing: it is required to scrape thin and evenly without leaving wild putty. After the putty is dry, use sandpaper to smooth and polish. ② Second full putty scraping and polishing: shrinkage cracks, uneven, to re-fill putty, putty dry, polished after cleaning. ③ Full putty scraping and polishing for the third time: check the uneven parts with 2m guiding feet. Then use putty to smooth, putty after drying, and then smooth, clean dust. ① brush over the latex paint: add the right amount of water or diluent.

What are the more suitable materials for car sealing strips

The use of PVC sealing strip temperature range is small, not environmentally friendly, and has a great impact on human health. Foreign developed countries and domestic Beijing and first-tier coastal cities have clearly restricted the use of PVC sealing strips. The use of PVC sealing strips will gradually decrease, especially in high-end industries. Silicone rubber sealing strip has good weather resistance and low temperature resistance, but its tear strength is low and the price is high, so its application field is limited. EPDM sealing strip has excellent performance, but the price is high, the color is single, and the processing is complicated. It is only suitable for dynamic sealing occasions with frequent switching actions.
