Ho isa bohōleng bo itseng, zinc stearate e ka nkela stearic acid le zinc oxide sebaka ka karolo e itseng, empa stearic acid le zinc oxide ka har'a rabara li ke ke tsa arabela ka botlalo 'me tsa ba le liphello tsa tsona.
Zinc oxide le stearic acid li theha sistimi ea ts'ebetso tsamaisong ea sebabole sa vulcanization, 'me mesebetsi ea eona e meholo ke e latelang:
1. Sistimi ea ho kenya tšebetsong vulcanization:
ZnO e arabela le SA ho hlahisa sesepa sa zinki, e ntlafatsang ho qhibiliha ha ZnO ka har'a rabara, 'me e sebelisana le li-accelerator ho theha motsoako o nang le ho qhibiliha ho hotle ka har'a rabara, e kenya tšebetsong li-accelerator le sebabole, 'me e ntlafatsa katleho ea vulcanization.
2. Eketsa bongata ba li-vulcanizate tse hokahanyang:
ZnO le SA di bopa letswai la zinki le qhibilihang. Letswai la zinki le kentswe ka sehokelo se hokahantsweng ka sefapano, se sireletsang sehokelo se fokolang, se etsa hore vulcanization e thehe sehokelo se sekgutshwane se hokahantsweng ka sefapano, se eketsa dibopeho tse ntjha tse hokahantsweng ka sefapano, mme se eketsa bongata ba dibopeho tse hokahantsweng.
3. Ntlafatsa khanyetso ea botsofali ea rabara e qhibilihisitsoeng:
Nakong ea tšebeliso ea rabara e nang le vulcanized, khokahano ea polysulfide ea robeha 'me hydrogen sulfide e hlahisoang e tla potlakisa botsofali ba rabara, empa ZnO e arabela le hydrogen sulfide ho hlahisa zinc sulfide, e jang hydrogen sulfide le ho fokotsa ho bola ha catalytic ea hydrogen sulfide marangrang a hokahaneng; ho phaella moo, ZnO e ka roka litlamo tsa sebabole tse robehileng le ho tsitsisa litlamo tse hokahaneng.
4. Mekhoa e fapaneng ea ho bonahatsa:
Litsamaisong tse fapaneng tsa ho hokahanya vulcanization, mokhoa oa ts'ebetso ea li-accelerator tse fapaneng tsa vulcanization o fapane haholo. Tšusumetso ea karabelo ea ZnO le SA ho theha setsi sa zinc stearate le eona e fapane le ea ho sebelisa zinc stearate feela.
