Matsayin stearic acid da zinc oxide a cikin ƙirar roba

Har zuwa wani lokaci, zinc stearate na iya maye gurbin stearic acid da zinc oxide, amma stearic acid da zinc oxide a cikin roba ba za su iya amsawa gaba ɗaya ba kuma suna da nasu tasirin.

Zinc oxide da stearic acid suna samar da tsarin kunnawa a cikin tsarin vulcanization na sulfur, kuma manyan ayyukansa sune kamar haka:

1. Kunna tsarin vulcanization:
ZnO yana amsawa tare da SA don samar da sabulun zinc, wanda ke inganta narkewar ZnO a cikin roba, kuma yana hulɗa tare da accelerators don samar da hadaddun tare da kyawawa mai kyau a cikin roba, yana kunna accelerators da sulfur, kuma yana inganta aikin vulcanization.

2. Haɓaka ɗimbin haɗin kai na vulcanizates:
ZnO da SA suna samar da gishirin zinc mai narkewa.Gishirin zinc yana chelated tare da haɗin haɗin giciye, wanda ke kare raƙuman haɗin gwiwa, yana haifar da vulcanization don samar da gajeren haɗin haɗin giciye, yana ƙara sabon haɗin haɗin giciye, kuma yana ƙara yawan haɗin giciye.

3. Inganta juriyar tsufa na roba mai ɓarna:
A lokacin amfani da vulcanized roba, polysulfide bond karya kuma samar da hydrogen sulfide zai hanzarta tsufa na roba, amma ZnO amsa da hydrogen sulfide don samar da zinc sulfide, wanda cinye hydrogen sulfide da kuma rage catalytic bazuwar hydrogen sulfide a kan giciye. - hanyar sadarwa mai alaƙa;Bugu da kari, ZnO na iya dinka karyewar igiyoyin sulfur da kuma daidaita shaidu masu alaka da giciye.

4. Hanyoyi daban-daban na tunani:
A cikin tsarin daidaitawa vulcanization daban-daban, tsarin aiwatar da matakan vulcanization daban-daban ya bambanta sosai.Tasirin amsawar ZnO da SA don samar da tsaka-tsakin tutiya stearate shima ya sha bamban da na amfani da sinadarin zinc stearate kadai.
