Nrog rau kev txhim kho kev paub txog kev tiv thaiv ib puag ncig hauv txhua lub tebchaws hauv ntiaj teb, cov kev cai tiv thaiv ib puag ncig thiab kev tswj hwm tau maj mam txhim kho, tshwj xeeb tshaj yog cov kev cai tu cev rau cov khoom yas xws li tshuaj, kev ua zaub mov, khoom siv txhua hnub, thiab cov khoom ua si yas. Cov hmoov txhuas thiab cadmium ntsev stabilizers thaum kawg yuav hloov tag nrho los ntawm cov tsis muaj tshuaj lom PVC stabilizers. . Kev tsim cov khoom siv yas txawv teb chaws yuav zoo li loj-teev thiab tshwj xeeb, kev tiv thaiv ib puag ncig muaj nuj nqis, thiab ua haujlwm tau zoo thiab ntau yam haujlwm. Kev tshawb fawb thiab kev tsim kho tshiab ntawm ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom PVC stabilizers tau dhau los ua qhov kev xav tsis thoob. Cov kev taw qhia tsis muaj tshuaj lom ntawm PVC cov cua sov stabilizers feem ntau yog tsom rau hauv ob qho tib si ntawm organotin thiab calcium-zinc composite heat stabilizers, thiab kev vam meej tau ua tiav hauv ob qho tib si. Nws yog feem ntau tshwm sim nyob rau hauv kev tshawb fawb ua tau zoo thiab kev siv ntau ntawm organotin kub stabilizers sawv cev los ntawm Teb Chaws Asmeskas, thiab kev nrov npe thiab kev siv cov tshuaj tsis muaj tshuaj lom calcium-zinc composite heat stabilizers sawv cev los ntawm Tebchaws Europe, tab sis tus nqi ntawm organotin yog kim heev. Calcium-zinc composite stabilizer yuav kawg tsim lub neej yav tom ntej uas tsis muaj tshuaj lom PVC stabilizer system ntawm txhua lub teb chaws hauv ntiaj teb.
Siv nyob rau hauv cov kav dej, profiles, yeeb nkab fittings, daim hlau, txhaj tshuaj molding, tshuab molding zaj duab xis, cable khoom thiab lwm yam khoom yas;
