Rau qee zaum, zinc stearate tuaj yeem hloov stearic acid thiab zinc oxide, tiam sis stearic acid thiab zinc oxide hauv roj hmab tsis tuaj yeem ua tsis txaus siab thiab ob leeg muaj lawv tus cwj pwm.
Zinc oxide thiab stearic acid tsim ib qho kev ua kom nyob rau hauv lub sulfuration system, uas nws lub ntsiab functions yog raws li nram no:
1. Qhib siv lub npliag lus:
ZnO thiab SA tau tsim zinc xab npum, txhim kho cov kua dej ntawm ZnO nyob rau hauv roj hmab, thiab daim ntawv txoj hauv kev zoo solubility hauv roj hmab nrog accelerator, qhib accelerator thiab sulfur, thiab txhim kho efficiency ntawm vulcanization.
2. Ua rau kom muaj kev sib dhos sib txuas ntawm vulcanizates:
ZnO thiab SA ua cov kua roj zinc ntsev, uas yog chelate nrog cov hlua khi sib tshooj los tiv thaiv txoj hlua khoob uas tsis muaj zog, pab kom sulfide los tsim cov kab nrib luv luv sib ntxiv, ntxiv cov khoom sib dhos tshiab, thiab txhim kho kev sib dhos.
3, txhim kho kev laus ntawm cov roj hmab vulcanized:
Nyob hauv tus txheej txheem ntawm kev siv vulcanizates, daim ntawv cog lus ntawm polysulfide thiab cov hydrogen sulfide generated yuav ua rau cov laus siv roj hmab. Txawm li cas los xij, ZnO sib thooj nrog hydrogen sulfide los ua zinc sulfide, uas haus hydrogen sulfide thiab txo cov catalytic decomposition ntawm hydrogen sulfide nyob rau hauv qhov crosslinked network.In addition, ZnO tuaj yeem suture cov nyiaj qij txha tawg thiab tswj kom cov nyiaj sib koom ua ke.
4. Lub tswv yim zoo sib xws:
Nyob hauv lub cev sib txawv ntawm lub cev vulcanization, txoj kev txiav txim siab ntawm cov kev sib txawv ntawm vulcanization yog txawv heev, thiab qhov kev nqis tes ua ntawm ZnO reacting nrog SA los rau zinc stearate nrab yog txawv ntawm kev siv zinc stearate ib leeg.
Yog li, tus qauv tsim yuav tsum xaiv cov kev ua kom haum raws li cov tswv yim sib txawv.
