Ntchito Range

HP-669 imagwiritsidwa ntchito bwino pamakampani amphira ngati cholumikizira chapawiri organic poly sulfure silane.
HP-669 itha kugwiritsidwa ntchito mu mphira wowonongeka wokhala ndi zodzaza ngati silika, fiberglass, talc powder, mica powder ndi dongo ngati chothandizira.Itha kupititsa patsogolo mphamvu zolimbikitsira za ma fillers ndi ma rabara abrasive resistance resistance.
Ndiwoyenera kugwiritsidwa ntchito ngati chowonjezera cha rabara-vulcanizing agent ndi activator mu ma polima monga NR, IR, SBR, BR, NBR ndi EPDM.
Mu ndondomeko ya vulcanization, ndi crosslinking mlingo wa poly-sulfure alkyl ndi chimodzimodzi deoxidizing mlingo wa sulfure, choncho kuchita kukana deoxidization wa vulcanization, ndiyeno kusintha zazikulu kupinda katundu monga kutentha kumanga ndi ming'alu kukula .The anayi sulfure ma atomu amatha kukhala ngati activator ya vulcanization.
M'malo osunthika komanso osasunthika, Amagwiritsidwa ntchito popanga zinthu za rabara izi: tayala, payipi, mpukutu wa rabara, kumangirira, chingwe, nsapato ndi zida zoyambira zamakina.Ikhoza kupititsa patsogolo kukana kwa abrasive, kudula kukana ndi kupanikizika, kuchepetsa kutaya kwa hysteresis ndi hygroscopicity, kupititsa patsogolo makina ndi zomatira, ndikuwonjezera kukalamba kwa kutentha, modulus ndi moyo wosinthasintha.
Onjezani sulfure-silane kugwirizana wothandizila mu makampani tayala tayala, si kungochepetsa chiopsezo puncture monga kutentha kwambiri kuthamanga pa msewu wothamanga kapena nthawi yaitali, komanso kuchepetsa mpukutu kukana tayala, ndiye kuchepetsa kuwononga mafuta, kuchuluka kwa mpweya wa CO2 molingana ndi chitetezo cha chilengedwe pakuchepetsa mpweya.
