Kusvika pamwero wakati, zinc stearate inogona kutsiva stearic acid ne zinc oxide zvishoma, asi stearic acid ne zinc oxide murabha hazvigone kuita zvese uye zvine zvazvinoita.
Zinc oxide ne stearic acid zvinoumba sisitimu yekushanda mu sulfur vulcanization system, uye mabasa ayo makuru ndeaya anotevera:
1. Sisitimu yekubvisa tsvina:
ZnO inoshanda pamwe chete neSA kugadzira sipo ye zinc, iyo inovandudza kunyungudika kweZnO murabha, uye inosangana ne accelerators kuti igadzire complex ine kunyungudika kwakanaka murabha, inomutsa accelerators nesarufa, uye inovandudza kushanda zvakanaka kwe vulcanization.
2. Wedzera huwandu hwe cross-linking hwe vulcanizates:
ZnO neSA zvinoumba munyu we zinc unonyungudika. Munyu we zinc unosanganiswa ne cross-linked bond, iyo inodzivirira cross-linked bond, inoita kuti vulcanization iite short cross-linked bond, inowedzera cross-linked bonds itsva, uye inowedzera cross-linking density.
3. Kuvandudza kuramba kwekukwegura kwerabha rakanyungudutswa:
Munguva yekushandiswa kwerabha yakasanganiswa, polysulfide bond inotyoka uye hydrogen sulfide inogadzirwa inokurumidza kukwegura kwerabha, asi ZnO inosangana nehydrogen sulfide kuti igadzire zinc sulfide, iyo inoshandisa hydrogen sulfide uye inoderedza kuora kwehydrogen sulfide panetwork yakabatana; pamusoro pezvo, ZnO inogona kusona mabhondi esulfuri akatyoka uye kudzikamisa mabhondi akabatana.
4. Nzira dzakasiyana dzekufungisisa:
Munzira dzakasiyana dzekubatanidza vulcanization, mashandiro ekushanda kwe vulcanization accelerators akasiyana zvikuru. Mhedzisiro yeZnO neSA reaction pakugadzira zinc stearate intermediate yakasiyanawo nekushandisa zinc stearate chete.
