Ho isa bohōleng bo itseng, zinc stearate e ka nkela asiti ea stearic le zinc oxide sebaka, empa asiti ea stearic le zinc oxide tse ka har'a rabara li ke ke tsa sebetsa ka botlalo 'me tsa ba le litlamorao tsa tsona.
Zinc oxide le stearic acid li theha sistimi ea ts'ebetso ho sulfur vulcanization system, mme mesebetsi ea eona ea mantlha ke e latelang:
1. Sistimi ea ts'ebetso ea vulcanization:
ZnO e sebetsana le SA ho hlahisa sesepa sa zinki, e ntlafatsang ho qhibiliha ha ZnO ka rabara, 'me e sebelisana le li-accelerator ho etsa motsoako o nang le ho qhibiliha hamonate ka har'a rabara, e kenya tšebetsong li-accelerator le sebabole, le ho ntlafatsa ts'ebetso ea vulcanization.
2. Eketsa kholo ea khokahanyo ea li-vulcanizate:
ZnO le SA li theha letsoai la zinki le qhibilihang.Letsoai la zinki le chelated ka tlamo e amanang le sefapano, e sireletsang tlamo e fokolang, e etsa hore vulcanization e thehe tlamo e khuts'oane ea sefapano, e eketsa li-bond tse ncha tse amanang le sefapano, 'me e eketsa matla a ho kopanya.
3. Ntlafatsa khanyetso ea botsofali ea rabara e senyehileng:
Nakong ea ts'ebeliso ea rabara e nang le vulcanized, polysulfide bond breaks le hydrogen sulfide e hlahisoang e tla potlakisa botsofali ba rabara, empa ZnO e arabela ka hydrogen sulfide ho hlahisa zinc sulfide, e jang hydrogen sulfide le ho fokotsa ho bola ha hydrogen sulfide sefapanong. -hokahanngoa marang-rang;ho feta moo, ZnO e ka roka litlamo tsa sebabole tse robehileng le ho tsitsisa libonto tse hokahaneng.
4. Mekhoa e fapaneng ea ho bonahatsa:
Lits'ebetsong tse fapaneng tsa khokahano ea vulcanization, mokhoa oa ts'ebetso oa li-accelerator tse fapaneng tsa vulcanization o fapane haholo.Phello ea maikutlo a ZnO le SA ho theha zinc stearate intermediate e boetse e fapane le ea ho sebelisa zinc stearate feela.
