qhov zoo
Cov khoom siv roj hmab hluavtaws muaj cov cua sov ua haujlwm zoo, tiv thaiv txias, tiv thaiv corrosion thiab tsis tshua muaj kev cuam tshuam los ntawm ib puag ncig yam. Cov khoom siv roj hmab tuaj yeem siv tau ib txwm ntawm 60 degrees thiab 250 degrees.
Qhov tsis zoo
Lub ntsiab tsis zoo yog tias nws cov nyhuv tensile kuj tsis zoo, thiab lub zog tsim kua muag thiab cov khoom siv kho tshuab kuj tsis zoo. Yog li ntawd, hauv kev tsim cov khau looj plab hlaub, nws tsis tuaj yeem siv ncaj qha rau cov roj hmab hluavtaws, thiab nws yog ib qho tsim nyog yuav tsum koom tes nrog ntau yam thiab cov txheej txheem kom ua tiav ntau yam kev ua yeeb yam ntawm cov khau roj hmab.
Lub cev muaj zog
Nws qhov kev ua tau zoo sib txawv ntawm monomer mus rau monomer, thiab kev ua haujlwm ntawm ob peb ntau yam zoo ib yam li cov roj hmab ntuj. Qee cov roj hmab hluavtaws muaj qhov kub thiab txias, tiv thaiv kev laus, kev laus ua haujlwm, kev tiv thaiv corrosion lossis roj tsis kam rau cov roj hmab ntuj.
Cov khoom siv tshuaj
Synthetic roj hmab yog ntau yam polymer tebchaw uas yog polymerized los ntawm txawv monomers nyob rau hauv qhov kev txiav txim ntawm ib tug pib. Cov monomers muaj xws li butadiene, styrene, acrylonitrile, isobutylene, chloroprene thiab lwm yam. Cov txheej txheem polymerization muaj xws li emulsion polymerization, kua polymerization, ncua kev kawm ntawv polymerization, thiab bulk polymerization.
