Kugwiritsa ntchito kwaphula la polyethylenemu PVC kutentha stabilizers.Ma stabilizers otentha ndi amodzi mwa magulu ofunikira othandizira kukonza pulasitiki.Kubadwa ndi chitukuko cha kutentha stabilizers ndi PVC resins ndi synchronous, ndipo makamaka ntchito pokonza PVC utomoni.Chifukwa chake, kuchuluka kwa zowongolera kutentha kwa utomoni wa PVC ndi zinthu zofewa komanso zolimba mu PVC ndizogwirizana kwambiri.

Mafuta nawonso ndi ofunikira kwambiri popanga ndi kukonza zowongolera kutentha.Dongosolo labwino lopaka mafuta limakhala ndi kusakhazikika kocheperako, kuwongolera bwino komanso kuyendetsa bwino, ndipo limatha kuwongolera kutentha kwapamwamba kwa stabilizer, kukulitsa nthawi yokhazikika yamafuta, kuchepetsa zonyansa ndi mpweya, komanso kumathandizira kukana kwanyengo kwa chinthucho.
Zotsatira za kutentha stabilizer
(1) Pokonza utomoni, kuteteza kapena kulepheretsa kuchotsa HCl ndi kutayika kwa mtundu chifukwa cha kuchotsa HCl.
(2) M'kati mwa moyo wautumiki wabwino wa mankhwalawa, sungani kukhazikika kwake kokwanira kwa kutentha, kuchepetsa kuwonongeka komwe kumachitika chifukwa cha kutentha, kuwala ndi kuwonjezera moyo wake wautumiki.

Njira yogwiritsira ntchito kutentha kwa stabilizer
(1) Bwezerani HCl yopangidwa panthawi ya kuwonongeka kwa PVC;
(2) M'malo osakhazikika allyl klorini atomu kapena tertiary carbon klorini atomu mu PVC molekyulu ziletsa kuchotsa PVC ndi HCL;

(3) Kuchita ndi ma radicals aulere kuti athetse kusamutsidwa kwa ma radicals aulere;
(4) Kuchita kowonjezera ndi ma conjugated ma bond awiri kuti muchepetse utoto;

(5)Kuletsa makutidwe ndi okosijeni wa PVC;
(6) Passivation wa ayoni zitsulo ndi chothandizira HCl kuchotsa.
