Iyo synergistic mhedzisiro ye organic tin uye poda calcium zinc stabilizers mu polyvinyl chloride (PVC):
Organic tin stabilizers (thiol methyl tin) imhando inowanzoshandiswa yePVC heat stabilizer. Ivo vanoita ne acidic hydrogen chloride (HCl) muPVC kugadzira munyu usingakuvadzi (senge tini chloride), nokudaro kudzivirira kuunganidzwa kweHCl uye kuderedza kuderera uye kutsvuka kwePVC zvinhu.
Powder calcium zinc stabilizer musanganiswa wecalcium uye zinc munyu, kazhinji inowedzerwa nenzira yehupfu hwakatsetseka kuPVC. Zvose calcium uye zinc ions zvine simba rekudzikamisa PVC. Calcium ions inogona kuderedza zvinhu zvine acidic zvinogadzirwa muPVC uye kuumba yakagadzikana calcium salt compounds. Zinc ions inopindirana nehydrogen peroxide (HCl) muPVC kugadzira mishonga isingakuvadzi uye kudzivirira kuunganidzwa kweHCl.
Kana organic tin uye poda calcium zinc stabilizers zvinogara muPVC, zvinogona kukurudzirana uye kuvandudza kugona kurapa HCl. Organic tin inogona kupa humwe hutsika hwekudzikisa huwandu hweHCl inogadzirwa, nepo upfu hwe calcium zinc stabilizers hunogona kupa yakawanda calcium uye zinc ions, zvichiwedzera kudzivirira kuunganidzwa kweHCl. Kuburikidza neiyi synergistic mhedzisiro, organic tin uye poda calcium zinc stabilizers inogona kuwedzera kugadzikana kwekupisa kwezvinhu zvePVC, kuvandudza hupenyu hwavo hwesevhisi uye kugadzikana kwekuita.
Izvo zvinofanirwa kucherechedzwa kuti huwandu uye chikamu che organic tin uye calcium zinc stabilizers inoda kugadziridzwa zvine musoro zvichienderana nezvinodiwa uye mashandisirwo enzvimbo yePVC zvigadzirwa, kuitira kuti uwane yakanakisa synergistic mhedzisiro. Panguva imwecheteyo, zvinofanirwa kutarisisa kuchengetedzeka uye nyaya dzezvakatipoteredza panguva yekushandiswa kudzivirira mhedzisiro yakaipa pahutano hwevanhu uye nharaunda.
