硅膠管的環(huán)保特性有哪些
硅膠管條和硅膠異形管條可分為擠出管、異形管條。主要由硅膠又稱硅橡膠生膠加到雙輥煉膠機上或密閉捏合機中，逐漸加入白碳黑及其它助劑反復煉制均勻，按行業(yè)產品技術標準要求，通過擠出制成產品。
Silicone tube strip and silica gel special tube bar can be divided into extrusion tube and special-shaped tube strip. It is mainly made of silica gel and silicone rubber to double roll rubber machine or closed kneader. White carbon black and other additives are gradually added, and the products are extruded in accordance with the technical standards of the industry.
硅膠因其獨特的環(huán)保特性，越來越受人們青睞，逐步取代其他材料產品，比如廚房用具、嬰兒用品等等與人們生活息息相關的產品！
Silica gel, because of its unique environmental characteristics, is becoming more and more popular, gradually replacing other materials, such as kitchen appliances, baby products and so on with people's life closely related products!
1、硅膠原材料按來源可分為國產料和進口料。
1, silica gel raw materials can be divided into domestic materials and imported materials according to their sources.
國產料主要有：東爵，宏達，新安江，藍星等較大的生產商；
The main products are: Dong Jue, Hongda, Xin'An River, LAN-STAR and so on.
進口料主要有：日本信越、東芝，美國道康寧，法國羅帝亞，德國瓦克等等。
The main imports are: Japan's Xinyue, Toshiba, Dow Corning, France rodasia, Germany Wacker and so on.
2、硅膠原材料按性能來分可分為普通硅膠和氣象硅膠。
2. Silica gel raw materials can be divided into ordinary silica gel and meteorological silica gel according to their properties.
普通硅膠又名沉淀硅膠
Common silica gel also known as precipitated silica gel
