Dab Tsi Yog Qhov Sib Txawv Ntawm Roj Hmab Gasket Thiab Silicone Gasket

Roj hmab gasket rubber gasket Cov ntawv ntim cov roj hmab roj hmab uas ntim nruab nrab ntawm ob qhov chaw nruab nrab ntawm cov hlau thaiv lossis lwm qhov txuas sib txuas tau hu ua lub thawv ntim roj hmab. Nws tuaj yeem ua los ntawm molding txoj kev, los yog tuaj yeem punched nrog zaj duab xis vulcanized. Nws tuaj yeem siv dav hauv txhua yam ntawm cov cuab yeej siv tshuab, ua si lub luag haujlwm ntawm gasket, sib khi, cushioning thiab lwm yam.

Silica gel Silicon dioxid alias: Silicone rubber yog cov khoom siv tshaj tawm adsorption, ib qho tshuaj amorphous, nws cov tshuaj lom neeg yog mSiO2 nH2O, insoluble hauv dej thiab cov kuab tshuaj, tsis muaj tshuaj lom, tsis muaj ntxhiab, ruaj khov tshuaj lom neeg, tsuas yog muaj alkalis thiab hydrofluoric acid. Nws tsis cuam tshuam nrog ib qho khoom twg. Ntau hom silica gel tsim cov qauv sib txawv microporous vim lawv cov qauv tsim khoom sib txawv. Cov tshuaj lom neeg thiab cov qauv ntawm lub cev ntawm silica gel txiav txim siab txog cov yam ntxwv uas muaj ntau yam khoom siv sib txawv yog qhov nyuaj los hloov: cov adsorption kev ua tau zoo, Zoo thermal stability, tshuaj lom neeg ruaj khov, siab muaj zog, thiab lwm yam Raws li nws cov pore loj, silica gel tau muab faib mus rau hauv: macroporous silica gel, ntxhib pore silica gel, hom B silica gel, thiab zoo tawv tawv silica gel.
