A tlem berah chuan zinc stearate hian stearic acid leh zinc oxide te chu a then a thlak thei a, mahse rubber-a stearic acid leh zinc oxide te hian an react kim thei lo va, an pahnih hian an chanvo an nei thei.
Zinc oxide leh stearic acid te hian sulfuration system ah activation system an siam a, an hnathawh ber chu hetiang hi a ni:
1. Vulcanization system activate a ni a:
ZnO leh SA te hian zinc soap an siam thei a, rubber-a ZnO solubility an ti tha thei a, rubber-a solubility tha tak nei complex an siam thei a, accelerator leh sulfur an tichak a, vulcanization efficiency. an ti tha bawk.
2. Vulcanizates te crosslinking density tihpun:
ZnO leh SA te hian soluble zinc salts an siam a, chu chuan crosslinked bonds hmangin a chelate a, chu chuan bonds chak lo te a venghim a, sulfide chu crosslinked bonds tawi tak a siam thei a, crosslinked bonds thar a dah thei a, crosslinked density a ti tha bawk.
3, Vulcanized rubber-a tar chakna (aging resistance) siam \\hat:
Vulcanizates hman a nih lai hian polysulfide bond breaks leh hydrogen sulfide siam chhuah te hian rubber. tar chakna chu a ti chak ang a, mahse ZnO chuan hydrogen sulfide nen an inzawm a, zinc sulfide an siam a, chu chuan hydrogen sulfide a ei a, crosslind network-a hydrogen sulfide-a catalytic decomposition a ti tlem a, chu chu additional a ni a, Zno-te chuan an ti thei a ni. crosslinked bond. a ni.
4. Reflection mechanism hrang hrang:
Vulcanization coordination system hrang hrangah chuan Vulcanization promoter hrang hrangte action mechanism chu a danglam hle a, ZnO-in SA nena a action mechanism chu zinc stearmediate siam tura action mechanism pawh zinc stearate alone. hman dan nen a danglam bawk.
Chuvangin, formula design hian design idea hrang hrang angin coordination dik tak a thlan a ngai a ni.
