Mtundu wa Ntchito

HP-669 imagwiritsidwa ntchito bwino mumakampani opanga rabara ngati cholumikizira cha polysulfure silane chomwe chimagwira ntchito ziwiri.
HP-669 ingagwiritsidwe ntchito mu dongosolo la rabara lopangidwa ndi vulcanized ndi zinthu zodzaza monga silica, fiberglass, talc powder, mica powder ndi dongo ngati chowonjezera mphamvu. Ikhoza kusintha mphamvu zolimbitsa za zodzaza ndi mphamvu zoletsa rabara.
Ndi yoyenera kugwiritsidwa ntchito ngati chowonjezera cha rabara—chothandizira kuwononga ndi kuyambitsa zinthu mu ma polima monga NR, IR, SBR, BR, NBR ndi EPDM.
Mu ndondomeko ya vulcanization, kuchuluka kwa crosslinking kwa poly-sulfur alkyl kumakhala kofanana ndi kuchuluka kwa deoxidizing kwa sulfure, kotero imagwira ntchito yolimbana ndi deoxidization ya vulcanization, kenako imawongolera mphamvu zopindika monga kutentha komwe kumawonjezeka ndi kufalikira kwa ming'alu. Maatomu anayi a sulfure amatha kugwira ntchito ngati activator ya vulcanization.
Mu mikhalidwe yosinthasintha komanso yosasinthasintha, imagwiritsidwa ntchito popanga zinthu za rabara izi: tayala, payipi, rabara yozungulira, lamba, chingwe, nsapato ndi zinthu zoyambira makina. Imatha kupititsa patsogolo kukana kwa abrasive, kukana kudula ndi kukana kupanikizika, kuchepetsa kutayika kwa hysteresis ndi hygroscopicity, kusintha mphamvu za makina ndi zomatira, ndikuwonjezera magwiridwe antchito okalamba a kutentha, modulus ndi moyo wosinthasintha.
Kuwonjezera cholumikizira cha sulfure-silane mumakampani opanga matayala a rabara, sikuti kumangochepetsa chiopsezo cha kubowoka chifukwa kutentha kwambiri kumayenda pamsewu wothamanga kwambiri kapena kwa nthawi yayitali, komanso kuchepetsa kukana kwa tayala, kenako kuchepetsa kugwiritsa ntchito mafuta, kuchuluka kwa mpweya wa CO2 kuti kuteteze chilengedwe cha kuchepetsa mpweya.
