Long sampela mak, zinc stearate inap senisim hap bilong stearik asit na zinc oksait, tasol stearik asit na zinc oksait long raba i no inap mekim gut wok na tupela i gat ol wok bilong ol yet.
Zinc oxide na stearic acid i kamapim wanpela sistem bilong wokim ol samting insait long sistem bilong salfa, em ol bikpela wok bilong en i olsem:
1. sistem bilong vulkenisasen i wok:
ZnO na SA i ken kamapim zinc sop, kamapim gutpela solubiliti bilong ZnO long raba, na kamapim kompleks wantaim gutpela solubiliti long raba wantaim akselereta, aktivim akselereta na salfa, na kamapim gutpela wok bilong vulcanization.
2. Inkrisim kroslink densiti bilong ol vulkenizet:
ZnO na SA i save kamapim ol sol bilong zinc i save solut, na ol i save putim ol rop i gat kros long en bilong lukautim ol samting i no strong, na dispela i mekim na salfaid inap kamapim ol sotpela kros i gat ol narapela narapela bon, na ol i putim ol nupela kros i gat kroslink, na ol i kamapim gut densiti bilong kroslinked. .
3, mekim raba bilong raba i go lapun i kamap lapun:
In the process of using vulcanizates, the polysulfide bond breaks and the hydrogen sulfide generated will accelerate the aging of rubber. However, ZnO interacts with hydrogen sulfide to generate zinc sulfide, which consumes hydrogen sulfide and reduces the catalytic decomposition of hydrogen sulfide on the crosslinked network.In addition, ZnO can suture the broken salfa bon na stebilisim kroslink bon.
4. Ol kain kain rot bilong tingim:
Long ol narapela narapela vulkenisasen kodinesen sistem, eksen mekanisme bilong ol narapela narapela vulcanization promota i narapela kain tru, na eksen mekanisme bilong ZnO i wok wantaim SA long kamapim zink stearate intamediet tu i narapela kain long yusim zink stearate tasol.
Olsem na, fomula disain i mas makim stretpela kodinesen bihainim ol narapela narapela tingting bilong disain.
