1) Yamwani ndikuchepetsa HCL, kuletsa mphamvu yake yothandiza. Mtundu uwu wa stabilizer umaphatikizapo mchere wotsogolera, sopo wachitsulo wa organic acid, mankhwala a organotin, mankhwala a epoxy, mchere wa inorganic salt, ndi mchere wa thiol wachitsulo. Amatha kuchitapo kanthu ndi HCL ndikuletsa momwe PVC imachotsera HCL.
2) Kusintha maatomu osakhazikika a klorini mu mamolekyu a PVC kumalepheretsa kuchotsedwa kwa HCL. Ngati organic tini stabilizer ikugwirizanitsa ndi ma atomu osakhazikika a klorini a mamolekyu a PVC, tini ya organic idzalowetsedwa m'malo ndi maatomu a klorini osakhazikika mumagulu ogwirizanitsa.
3) Zomwe zimapangidwira ndi mawonekedwe a polyene zimasokoneza mapangidwe a dongosolo lalikulu la conjugated ndikuchepetsa utoto. Unsaturated acid salt kapena esters amakhala ndi ma bond awiri, omwe amakumana ndi ma diene owonjezera ndi mamolekyu a PVC polumikizana ndi ma bond awiri, potero amasokoneza kapangidwe kawo kolumikizana ndikuletsa kusintha kwamtundu.
4) Kugwira ma radicals aulere ndikuletsa machitidwe a okosijeni, stabilizer yotentha iyi imatha kukhala ndi zotsatirapo imodzi kapena zingapo.
The abwino PVC kutentha stabilizer ayenera multifunctional mankhwala kapena chisakanizo cha zipangizo kuti angathe kukwaniritsa ntchito zotsatirazi: choyamba, m'malo yogwira ndi wosakhazikika m'malo; Chachiwiri ndikuyamwa ndi kusokoneza HCL yomwe imatulutsidwa panthawi ya PVC, kuchotsa zotsatira zowonongeka za HCL; Chachitatu ndikuchepetsa kapena kuchepetsa ayoni achitsulo ndi zonyansa zina zomwe zimathandizira pakuwonongeka; Chachinayi, mitundu yosiyanasiyana yamachitidwe amankhwala imatha kuletsa kukula kwa zomangira zopanda unsaturated ndikuletsa utoto wowonongeka; Chachisanu, imakhala ndi chitetezo komanso chotchinjiriza pa kuwala kwa ultraviolet. Nthawi zambiri, zowongolera kutentha zimagwiritsidwa ntchito mophatikizana potengera momwe zimagwirira ntchito, ndipo kugwiritsidwa ntchito kwawo pawokha ndikosowa. Komanso, mitundu yambiri imakhala yaufa, ndipo ina imakhala ndi mankhwala oopsa kwambiri. Pofuna kuwongolera kugwiritsa ntchito, kupewa kuwononga fumbi, kuchepetsa zinthu zapoizoni kapena m'malo mwa zinthu zopanda poizoni, mitundu yambiri yamagulu okhazikika apangidwa mdziko muno komanso padziko lonse lapansi m'zaka zaposachedwa. Mwachitsanzo, German Bear brand composite stabilizer series, komanso organic tin kapena composite organic tin stabilizers ochokera kumayiko monga United States, Germany, Japan, ndi Netherlands, onse ali ndi gawo lalikulu pamsika ku China. Chifukwa chake, ndikofunikira kwambiri kuti chitukuko cha mafakitale apulasitiki aku China chilimbikitse kugwiritsa ntchito zida zatsopano zophatikizira zomwe zimakhala zogwira mtima, zotsika mtengo, zopanda fumbi, zopanda poizoni kapena zowopsa.
