1) Kureka no gutesha agaciro HCL, kubuza ingaruka za auto catalitike.Ubu bwoko bwa stabilisateur burimo imyunyu ngugu, isabune ya acide organic acide, ibinyabuzima bya organotine, ibinyabuzima bya epoxy, imyunyu ngugu, hamwe nu munyu wa thiol.Barashobora kwitwara hamwe na HCL no kubuza reaction ya PVC kugirango bakure HCL.
2) Gusimbuza atome ya chlorine idahindagurika muri molekile ya PVC ibuza gukuraho HCL.Niba amabati kama ya stabilisateur ahuza na atome ya chlorine idahindagurika ya molekile ya PVC, amabati kama azasimburwa na atome ya chlorine idahindagurika mumubiri uhuza.
3) Kwiyongera kwinyubako hamwe na polyene ihungabanya imiterere ya sisitemu nini ya conjugated kandi igabanya amabara.Umunyu wa acide idahagije cyangwa esters irimo imigozi ibiri, ihura na diene yongeyeho na molekile ya PVC ihuza imigozi ibiri, bityo igahagarika imiterere yabyo kandi ikabuza ihinduka ryamabara.
4) Gufata radicals yubusa no gukumira okiside, iyi stabilisateur yumuriro irashobora kugira ingaruka imwe cyangwa nyinshi.
Icyiza cyiza cya PVC kigomba kuba ibintu byinshi cyangwa uruvange rwibikoresho bishobora kugera kubikorwa bikurikira: icya mbere, gusimbuza ibintu bikora kandi bidahindagurika;Iya kabiri ni ugukuramo no gutesha agaciro HCL yarekuwe mugihe cyo gutunganya PVC, ikuraho ingaruka ziterwa na catalitiki yangiza ya HCL;Icya gatatu ni ugutesha agaciro cyangwa gutambutsa ion ibyuma nibindi byangiza byangiza uruhare mukwangirika;Icya kane, uburyo butandukanye bwimiti yimiti irashobora kubuza gukomeza gukura kwimigozi idahagije kandi ikabuza amabara gutesha agaciro;Icya gatanu, ifite ingaruka zo gukingira no gukingira urumuri ultraviolet.Mubisanzwe, stabilisateur yubushyuhe ikoreshwa muguhuza ukurikije imikorere yihariye, kandi imikoreshereze yabantu ni gake.Byongeye kandi, ubwoko bwinshi buri muburyo bwa poro, hamwe nubumara bwangiza cyane.Mu rwego rwo koroshya imikoreshereze, gukumira uburozi bw’umukungugu, kugabanya ibintu by’ubumara cyangwa kubisimbuza ibintu bidafite uburozi, ubwoko bwinshi bwa stabilisateur yibikoresho byatejwe imbere haba mu gihugu ndetse no mu mahanga mu myaka yashize.Kurugero, Ikidage cya Bear cyo mu bwoko bwa Bear compte stabilisateur, hamwe na tin organic cyangwa tin organic stabilisateur biva mu bihugu nka Amerika, Ubudage, Ubuyapani, n’Ubuholandi, byose bifite isoko ryinshi mu Bushinwa.Niyo mpamvu, byihutirwa iterambere ry’inganda za pulasitike mu Bushinwa kugira ngo duteze imbere byimazeyo ikoreshwa rya stabilisateur nshya ikora neza, ihendutse, idafite ivumbi, idafite uburozi cyangwa uburozi buke.
