Udindo wa stearic acid ndi zinc oxide mu kapangidwe ka rabara

Kufikira pamlingo winawake, zinc stearate imatha kusintha pang'ono stearic acid ndi zinc oxide, koma stearic acid ndi zinc oxide mu rabara sizingagwire ntchito mokwanira ndipo zimakhala ndi zotsatira zake.

Zinc oxide ndi stearic acid zimapanga dongosolo loyambitsa mu dongosolo la sulfure vulcanization, ndipo ntchito zake zazikulu ndi izi:

1. Dongosolo loyambitsa vulcanization:
ZnO imagwira ntchito ndi SA popanga sopo wa zinc, zomwe zimapangitsa kuti ZnO isungunuke bwino mu rabara, ndipo imagwirizana ndi ma accelerator kuti apange complement yokhala ndi kusungunuka bwino mu rabara, imayambitsa ma accelerator ndi sulfure, komanso imapangitsa kuti vulcanization igwire bwino ntchito.

2. Wonjezerani kuchuluka kwa ma vulcanizates omwe amalumikizana:
ZnO ndi SA amapanga mchere wa zinc wosungunuka. Mchere wa zinc umayikidwa ndi chomangira cholumikizidwa, chomwe chimateteza chomangira chofooka, chimapangitsa kuti vulcanization ipange chomangira chachifupi cholumikizidwa, chimawonjezera zomangira zatsopano zolumikizidwa, ndikuwonjezera kuchuluka kwa zomangira.

3. Kuonjezera kukana kukalamba kwa mphira wokhuthala:
Pogwiritsa ntchito rabala yosungunuka, polysulfide bond imasweka ndipo hydrogen sulfide yopangidwa idzafulumizitsa ukalamba wa rabala, koma ZnO imagwira ntchito ndi hydrogen sulfide kuti ipange zinc sulfide, yomwe imadya hydrogen sulfide ndikuchepetsa kuwonongeka kwa hydrogen sulfide pa netiweki yolumikizidwa; kuphatikiza apo, ZnO imatha kusoka ma bond a sulfure osweka ndikukhazikitsa ma bond olumikizidwa.

4. Njira zosiyanasiyana zowunikira:
Mu machitidwe osiyanasiyana ogwirizanitsa ma vulcanization, njira yogwirira ntchito ya ma vulcanization accelerators osiyanasiyana ndi yosiyana kwambiri. Zotsatira za ZnO ndi SA reaction popanga zinc stearate intermediate ndizosiyananso ndi zomwe zimagwiritsidwa ntchito pogwiritsa ntchito zinc stearate yokha.
