Khoom Txhim Kho Ntawm Roj Hmab Ruaj Ntseg

1 fluorine roj hmab: nrog rau kev kub taub hau, yuav siv tau rau -30 degrees - + 250 degrees C cheeb tsam, muaj zog oxidation ua hauj, roj tsis ua hauj, acid thiab alkali tiv. Feem ntau siv hauv kev kub siab, siab nqus thiab siab siab cheeb tsam, tsim rau cov cheeb tsam cov roj. Vim yog nws cov khoom zoo heev, cov roj hmab siv roj hmab yog siv hauv roj av, tshuaj, aviation, aerospace thiab lwm lub tuam tsev

2. Cov xim roj hmab: nrog rau qhov siab thiab kub tsis tshua muaj siab, ntawm -70 degrees - + 260 degrees Celsius qhov kub thiab txias kom tuav zoo siv elasticity, thiab nws muaj zog, kev tiv thaiv huab cua thiab lwm yam zoo, nws yuav tsum raug siv los ua thermal machinery hauv gasket. Vim tsis muaj tshuaj muaj taug, nws tuaj yeem tsim hluav taws xob, rwb thaiv tsev thiab khoom siv roj hmab

3, nitrile roj hmab: nrog cov roj nplaum thiab cov khoom ua kom muaj zog, tiam sis tsis ua rau ketones, esters thiab chlorinated los ntawm cov xov xwm, yog li cov roj ntim khoom siv siv nitrile roj hmab

4, chloroprene roj hmab: nrog cov roj ua tsis zoo, hnyav ua haujlwm, tshuaj tawm thiab lwm yam khoom, tab sis tsis ua rau cov roj ntsha tuaj yeem, uas yog ua rau huab cua tsis muaj hnub nyoog thiab kev laus, kev ua tau zoo. Hauv kev tsim, neoprene yog siv los ua qhov rooj thiab qhov rais, sealing strips thiab diaphragms thiab sealing khoom rau kev xaim hluav taws xob

5, peb cov nyiaj ethylene propylene: nws muaj qhov kub zoo, cov huab cua ua haujlwm, kev laus thiab cov laus ua haujlwm, feem ntau cov qhov rooj thiab qhov rais sealing strip, automotive industry feem ntau siv

6, PTFE gasket yog PTFE thiab cov khoom siv roj hmab zoo, tshwj xeeb cov txheej txheem tshiab sealing khoom compound thiab nkag mus rau hauv, nws muaj cov yam ntxwv zoo ntawm PTFE thiab roj hmab, cov khoom muaj zoo heev corrosion kuj, thiab kub kub, tsis ua hauj, thiab muaj zoo elasticity thiab sealing ntawm
