Ilaa xad, zinc stearate wuxuu qayb ahaan beddeli karaa stearic acid iyo zinc oxide, laakiin stearic acid iyo zinc oxide ee ku jira caagga si buuxda uma fal celin karaan oo saameyntooda gaarka ah ma yeelan karaan.
Zinc oxide iyo stearic acid waxay sameeyaan nidaam firfircooni ah oo ku jira nidaamka gariirka sulfur, shaqooyinkiisa ugu muhiimsanna waa sidan soo socota:
1. Nidaamka kicinta gariirka:
ZnO wuxuu la falgalaa SA si uu u soo saaro saabuunta zinc, taas oo hagaajisa milmida ZnO ee cinjirka, waxayna la falgashaa dardar-qaadayaasha si ay u samayso isku-dhafan leh milmi wanaagsan oo cinjirka ah, waxay kicisaa dardar-qaadayaasha iyo sulfur, waxayna wanaajisaa hufnaanta vulcanization.
2. Kordhi cufnaanta isku xidhka ee vulcanizates:
ZnO iyo SA waxay sameeyaan cusbo zinc ah oo milmi karta. Cusbada zinc waxaa lagu dhejiyaa isku xidhka isku xidhka, kaas oo ilaaliya isku xidhka daciifka ah, wuxuu sababaa in isku xidhku uu sameeyo isku xidh gaaban oo isku xidhka ah, wuxuu ku daraa isku xidh cusub oo isku xidhka ah, wuxuuna kordhiyaa cufnaanta isku xidhka.
3. Hagaaji iska caabbinta gabowga ee cinjirka vulcanized:
Inta lagu jiro isticmaalka cinjirka la shiiday, xidhmada polysulfide way jabtaa, haydarojiin sulfide-na way soo dedejin doontaa gabowga cinjirka, laakiin ZnO waxay la falgashaa haydarojiin sulfide si ay u soo saarto zinc sulfide, kaas oo cuna haydarojiin sulfide isla markaana yareeya kala-goynta katalytic ee haydarojiin sulfide ee shabakadda isku xidhka; Intaa waxaa dheer, ZnO wuxuu toli karaa xidhmooyinka sulfur ee jabay wuxuuna xasilin karaa xidhmooyinka isku xidhka ah.
4. Hababka kala duwan ee milicsiga:
Nidaamyada isku-dubaridka vulcanization-ka ee kala duwan, habka ficilka ee dardar-geliyeyaasha vulcanization-ka ee kala duwan aad ayuu u kala duwan yahay. Saamaynta falcelinta ZnO iyo SA ee sameynta dhexdhexaadka zinc stearate sidoo kale way ka duwan tahay tan isticmaalka zinc stearate oo keliya.
