1. Ntsuab
Tsis muaj cov hlau hnyav (cov hlau lead, kev sib cais), tuaj yeem ua tau raws li cov qauv hauv lub tebchaws (xws li RHOS directive, REACH directive, etc.).
2. Resistance rau vulcanization muaj kuab paug.
Nyob rau hauv lub tshav pob ntawm PVC qhov rooj thiab qhov rais profiles, kev siv cov hlau lead kub stabilizer (ntau cov sulfur-muaj cov thee ua rau cov kua qaub los nag) nyob rau qee qhov chaw ntawm sab qaum teb Tuam Tshoj yog ib qho yooj yim los ua dub, thiab calcium zinc kub stabilizer yuav tsis txhob qias neeg.
3, zoo system switching yam ntxwv.
Thaum cov khoom siv hluav taws xob ua hluav taws xob sib xyaw ua ke tau hloov mus rau hauv organotin tshav kub stabilizer, kev sib kis kab mob yuav tshwm sim, ua rau cov nqi hloov pauv siab, thiab calcium zinc kub stabilizer tsis muaj cov tshuaj tiv thaiv nrog ob lub tshav kub stabilizer, thiab tus nqi ntawm kev hloov ntawm lawv yog tsawg. .
4, tsis tshua muaj ntom ntom, tuaj yeem tsim kom muaj cov calcium carbonate, txo cov nqi.
Piv nrog rau cov khoom siv hluav taws xob sib xyaw ua ke, cov calcium zinc kub stabilizer ntom ntom yog li 40% qis dua, thiab cov khoom siv PVC tsuas yog hloov cov cua sov stabilizer ntsuas qhov hnyav li ntawm 2% ntawm qhov nruab nrab.
