Product Application
Iyo yekunyungudika yeuracil iri pamusoro pe270 ℃, uye inogona kuchinjika kune iyo PVC yekugadzira maitiro pachayo.
Uracil inogona kutora HCL inogadzirwa panguva yekugadzira PVC uye kutsiva isina kugadzikana chlorine maatomu.
Kana yakashandiswa pamwe chete neZnSt2, uracil inogona kuita neZnC12 kugadzira simbi yakaoma, zvichiita kuti ZnC12 isashande uye kudzivirira "kupisa zinc", nekudaro kunowedzera kugadzikana kwePVC zvigadzirwa.
Iine theuracil/ZnSt2 compound stabilizer, zvose kuchena kwekutanga uye kugadzikana kwenguva refu zvinonyanya kunaka pane izvo zvine CaSt2/ZnSt2 compound stabilizer.
Whenuraciland ZnSt2 inoshandiswa pamwechete, yakanaka system yekudzikamisa mhedzisiro inowanikwa.
Iyo yakakurudzirwa kuwedzera chiyero cheiyo stabilizer mu calcium-zinc system ndeye 2-5% yehuwandu hwehuwandu hweiyo stabilizer.
Kudzivirirwa uye kuchengetedzwa
Inofanira kuchengetwa munzvimbo inotonhorera uye yakaoma. Inogona kuchengetwa kwemakore maviri pasi pemamiriro asina kuvhurwa. Kana chigadzirwa chacho chisina kushandiswa kumusoro, bhegi rekuzarura rinofanira kuvharwa zvakasimba.
