Kusvika kumwero wakati, zinc stearate inogona kutsiva stearic acid uye zinc oxide zvishoma, asi stearic acid uye zinc oxide murabha haigone kuita zvachose uye kuve nemhedzisiro yadzo.
Zinc oxide uye stearic acid inoumba activation system mune sulfur vulcanization system, uye mabasa ayo makuru ndeaya anotevera:
1. Activation vulcanization system:
ZnO inopindirana neSA kugadzira sipo yezinc, iyo inovandudza kunyungudika kweZnO murabha, uye inodyidzana nemaaccelerator kuti iumbe yakaoma ine kunyungudika kwakanaka murabha, inomisikidza accelerators nesarufa, uye inovandudza vulcanization kushanda zvakanaka.
2. Wedzera huwandu hwekubatanidza huzhinji hwemavulcanizates:
ZnO neSA zvinogadzira zinc munyu inonyungudika. Iyo zinc munyu inocherwa ne-cross-linked bond, iyo inodzivirira iyo isina kusimba chisungo, inoita kuti vulcanization igadzire pfupi-yakabatana bond, inowedzera mitsva-yakabatana mabhondi, uye inowedzera muchinjiko-inongedzo density.
3. Kuvandudza kuramba kuchembera kwerabha ine vulcanized:
Munguva yekushandiswa kwerabha ine vulcanized, iyo polysulfide bond inotyora uye inogadzirwa hydrogen sulfide inomhanyisa kuchembera kwerabha, asi ZnO inopindirana nehydrogen sulfide kugadzira zinc sulfide, iyo inoshandisa hydrogen sulfide uye inoderedza kuparara kwehydrogen sulfide pamuchinjiko. -yakabatana network; uyezve, ZnO inogona kusona yakatyoka mabhondi esarufa uye kudzikamisa ma bond akabatana.
4. Nzira dzekuratidzira dzakasiyana:
Mune akasiyana vulcanization coordination masisitimu, maitiro ekuita eakasiyana vulcanization accelerator akasiyana zvakanyanya. Mhedzisiro yeZnO uye SA reaction kuita zinc stearate yepakati zvakare yakasiyana neyekushandisa zinc stearate chete.
