Ngezinga elithile, i-zinc stearate ingathatha indawo ye-stearic acid kanye ne-zinc oxide ngokwengxenye, kodwa i-stearic acid kanye ne-zinc oxide enjolobeni azikwazi ukusabela ngokuphelele futhi zibe nemiphumela yazo.
I-zinc oxide kanye ne-stearic acid zakha uhlelo lokusebenza ohlelweni lwe-sulfur vulcanization, futhi imisebenzi yalo eyinhloko yile elandelayo:
1. Uhlelo lokuvuselela i-vulcanization:
I-ZnO iphendula ne-SA ukuze ikhiqize insipho ye-zinc, ethuthukisa ukuncibilika kwe-ZnO enjolobeni, futhi isebenzisana nezisheshi ukuze yakhe inhlanganisela enokuncibilika okuhle enjolobeni, isebenze izisheshi kanye nesibabule, futhi ithuthukise ukusebenza kahle kwe-vulcanization.
2. Khulisa ubuningi bokuxhumanisa kwama-vulcanizates:
I-ZnO kanye ne-SA zakha usawoti we-zinc oncibilikayo. Usawoti we-zinc uhlanganiswe nesibopho esixhumene, esivikela isibopho esibuthakathaka, sibangele ukuthi i-vulcanization yakhe isibopho esifushane esixhumene, sengeze izibopho ezintsha ezixhumene, futhi sandise ubuningi bokuxhumanisa.
3. Thuthukisa ukumelana nokuguga kwerabha evulcanized:
Ngesikhathi sokusetshenziswa kwerabha evulcanized, isibopho se-polysulfide siyaphuka kanye ne-hydrogen sulfide ekhiqizwayo kuzosheshisa ukuguga kwerabha, kodwa i-ZnO isabela ne-hydrogen sulfide ukuze ikhiqize i-zinc sulfide, edla i-hydrogen sulfide futhi inciphise ukubola kwe-catalytic kwe-hydrogen sulfide kunethiwekhi exhumene; ngaphezu kwalokho, i-ZnO ingathunga izibopho zesulfure eziphukile futhi izinzise izibopho ezixhumene.
4. Izindlela ezahlukene zokuzindla:
Ezinhlelweni ezahlukene zokuxhumanisa i-vulcanization, indlela yokusebenza kwama-accelerator ahlukene e-vulcanization ihluke kakhulu. Umphumela wokusabela kwe-ZnO kanye ne-SA ekwakheni i-zinc stearate intermediate nawo uhlukile kokusebenzisa i-zinc stearate yodwa.
