Ngokwezinga elithile, i-zinc stearate ingangena esikhundleni se-stearic acid ne-zinc oxide ngokwengxenye, kodwa i-stearic acid ne-zinc oxide erabha azikwazi ukusabela ngokuphelele futhi zibe nemiphumela yazo.
I-Zinc oxide ne-stearic acid zakha uhlelo lokuvula ohlelweni lwe-sulfur vulcanization, futhi imisebenzi yalo eyinhloko imi kanje:
1. Ukwenza kusebenze isistimu ye-vulcanization:
I-ZnO ihlangana ne-SA ukuze ikhiqize insipho ye-zinc, ethuthukisa ukunyibilika kwe-ZnO kurabha, futhi ixhumana nama-accelerator akhe inkimbinkimbi enokuncibilika okuhle kunjoloba, ivule ama-accelerator nesibabule, futhi ithuthukise ukusebenza kahle kokuvuvukala.
2. Khulisa ukuminyana okuhlanganayo kwama-vulcanizates:
I-ZnO ne-SA zakha usawoti we-zinc oncibilikayo.Usawoti we-zinc uhlotshaniswa ne-cross-linked bond, evikela isibopho esibuthakathaka, ibangela ukuthi i-vulcanization yakhe isibopho esifushane esixhumanisa, ingeze amabhondi amasha axhumene, futhi ikhulise ukuminyana kokuxhumanisa.
3. Thuthukisa ukumelana nokuguga kwenjoloba eshisiwe:
Ngesikhathi kusetshenziswa irabha enezinyosi, ukunqamuka kwesibopho se-polysulfide kanye ne-hydrogen sulfide ekhiqiziwe izosheshisa ukuguga kwenjoloba, kodwa i-ZnO isabela nge-hydrogen sulfide ukuze ikhiqize i-zinc sulfide, edla i-hydrogen sulfide futhi inciphise ukubola kwe-hydrogen sulfide esiphambanweni. -inethiwekhi exhunyiwe;ngaphezu kwalokho, i-ZnO ingathunga amabhondi esibabule aphukile futhi izinze amabhondi axhumene.
4. Izindlela ezihlukile zokubonisa:
Ezinhlelweni ezihlukene zokuxhumanisa i-vulcanization, indlela yokusebenza yama-accelerator ahlukene we-vulcanization ihluke kakhulu.Umphumela wokusabela kwe-ZnO kanye ne-SA ukwenza i-zinc stearate intermediate nayo ihlukile kulowo wokusebenzisa i-zinc stearate iyodwa.
