Pamlingo wina, zinc stearate imatha kulowa m'malo mwa stearic acid ndi zinc oxide, koma stearic acid ndi zinc oxide mu mphira sangathe kuchitapo kanthu ndikukhala ndi zotsatira zake.
Zinc oxide ndi stearic acid amapanga ma activation system mu sulfur vulcanization system, ndipo ntchito zake zazikulu ndi izi:
1. Njira yoyambitsa vulcanization:
ZnO imakumana ndi SA kuti ipange sopo wa zinki, womwe umathandizira kusungunuka kwa ZnO mu mphira, ndikumalumikizana ndi ma accelerator kuti apange zovuta zosungunuka bwino mu mphira, imayendetsa ma accelerator ndi sulfure, ndikuwongolera magwiridwe antchito.
2. Wonjezerani kachulukidwe ka ma vulcanizates:
ZnO ndi SA amapanga mchere wosungunuka wa zinki.Mchere wa zinc umatchedwa chelated ndi chomangira cholumikizira, chomwe chimateteza chomangira chofooka, chimapangitsa kuti vulcanization ipange mgwirizano waufupi wolumikizirana, imawonjezera zomangira zatsopano zolumikizirana, ndikuwonjezera kachulukidwe kolumikizana.
3. Limbikitsani kulimba kwa ukalamba wa rabara wovunda:
Pa ntchito mphira vulcanized, polysulfide chomangira yopuma ndi kwaiye hydrogen sulfide imathandizira kukalamba kwa mphira, koma ZnO amachitira ndi hydrogen sulfide kupanga zinki sulfide, amene amadya wa hydrogen sulfide ndi kuchepetsa kuwononga chothandizira wa hydrogen sulfide pamtanda. - network yolumikizidwa;Komanso, ZnO akhoza kusoka zomangira wosweka sulfure ndi kukhazikika zomangira mtanda.
4. Njira zowonetsera zosiyana:
M'machitidwe osiyanasiyana olumikizirana vulcanization, limagwirira ntchito zamitundu yosiyanasiyana ya vulcanization accelerator ndi yosiyana kwambiri.Zotsatira za ZnO ndi SA zomwe zimapanga zinc stearate wapakatikati ndizosiyananso ndi kugwiritsa ntchito zinc stearate yokha.
