Dab Tsi Muaj Peev Xwm Ntawm Cov Roj Hmab Barmat?

Cov khoom lag luam tseem ceeb ntawm cov roj hmab tawm yog: Silicone lev, nitrile roj hmab bar lev, fluorine roj hmab cov ntaub ntawv, lwm cov ntaub ntawv roj hmab. Silicone rubber muaj zoo heev thiab tsis kub tsis kam, tswj tau zoo elasticity hauv qhov kub ntawm -70 ° C rau 60260 ° C, tiv taus ozone thiab huab cua, thiab tsim nyog rau kev sib khi gaskets hauv thermomechanics. Cov mob tsis huv yuav siv tau los ua cov rwb thaiv tsev thaum tshav kub kub, rwb thaiv tsev cov khoom lag luam thiab cov khoom siv roj hmab kho mob. Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv zoo xws li dej tsis qab, nplaim taws rov qab, qhov kub tsis kam, hluav taws xob conductivity, tsis kam, thiab roj tsis kam. Nws yog dav siv hauv tshuab, electronics, kav dej thiab lwm yam kev lag luam.

Nitrile-Butadiene Roj Hmab (Nitrile-Butadiene Roj Hmab) yog cov polymer tsim los ntawm emulsion copolymerization ntawm butadiene thiab acrylonitrile. Nws yog lub npe hu rau nws zoo heev roj tsis kam, thiab tseem muaj zoo hnav tsis kam, kev laus tiv taus thiab roj ua hauj. Cov nruj. Yog li ntawd, nws yog dav siv nyob rau hauv kev lag luam roj hmab.

Cov roj hmab fluorine muaj qhov kub thiab txias tsis kam, tuaj yeem siv hauv ib puag ncig ntawm -20 ℃ －+200 ℃, tiv taus oxidants muaj zog, roj, kua qaub thiab alkalis. Feem ntau siv nyob rau hauv qhov kub thiab txias, lub tshuab nqus tsev siab thiab kev nyab xeeb siab, tab sis kuj tsim nyog rau cov roj ib puag ncig, dav siv hauv roj av, tshuaj, aviation, aerospace thiab lwm cov haujlwm. Lwm yam neoprene roj hmab, roj hmab ntuj, EPDM roj hmab, acrylic roj hmab thiab lwm cov txhuam tshwj xeeb. Nws tiv taus cov roj, acid, alkali, puas, kub thiab tsis kub.
