Dab Tsi Yog Qhov Sib Txawv Ntawm Roj Hmab Gasket Thiab Silicone Gasket
Dec 12, 2020
Dab tsi yog qhov sib txawv ntawm roj hmab gasket thiab silicone gasket
Cov roj hmab gasket rubber gasket rubber gasket yog ib hom ntawm cov khoom siv roj hmab roj hmab uas ntim nruab nrab ntawm ob qho chaw zoo li qub ntawm cov hlau tsis sib txuas lossis lwm qhov txuas txuas. Nws tuaj yeem ua los ntawm molding lossis vulcanized zaj duab xis. Nws tuaj yeem siv dav hauv txhua yam khoom siv kho tshuab, xws li gasket, foob, ntas thiab lwm yam.
Silicone rubber yog ib hom ntawm cov khoom siv tshaj tawm adsorption, uas yog nyob rau hauv cov tshuaj amorphous. Nws cov tshuaj lom neeg cov tshuaj yog msio2 nH2O, uas yog tsis txaus ntseeg hauv dej thiab ib qho kuab tshuaj, tsis muaj tshuaj lom thiab tsis qab, nrog cov tshuaj muaj zog nyob ruaj khov. Nws tsis cuam tshuam nrog rau ib qho tshuaj tsuas yog muaj zog alkali thiab hydrofluoric acid. Txawv ntawm silica gel sib txawv muaj cov qauv sib txawv microporous vim lawv cov qauv tsim khoom sib txawv. Cov tshuaj sib xyaw ua ke thiab kev teeb tsa lub cev ntawm silica gel txiav txim siab tias nws muaj ntau yam ntxwv uas tsis yooj yim hloov los ntawm lwm cov ntaub ntawv zoo: muaj cov adsorption kev ua tau zoo, zoo thermal stability, tshuaj lom neeg ruaj khov, siab zog lub zog, thiab lwm yam. macroporous silica gel, macroporous silica gel, B-hom silica gel thiab microporous silica gel raws li lawv cov pore loj.
