Qhov sib txawv ntawm calcium zinc stabilizer thiab composite lead salt stabilizer:

Calcium zinc stabilizer thiab composite lead salt stabilizer yog hais txog PVC heat stabilizers, uas ua lub luag haujlwm hauv thermal stability hauv PVC cov khoom tsim. Qhov sib txawv ntawm ob yog raws li nram no:
Cov tshuaj calcium zinc heat stabilizers ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig thiab tam sim no siv dav. Nws cov yam ntxwv suav nrog cov hauv qab no:
1. Qhov tseem ceeb tshaj plaws ntawm cov calcium zinc stabilizers yog tias lawv siv rau hauv cov khoom lag luam pob tshab thiab opaque hauv cov ntaub ntawv siv tshuaj lom neeg, nrog rau kev siv tau zoo.
2. Tus nqi qis dua li ntawm organotin.
3. Nws muaj kev sib raug zoo thiab kev sib koom tes nrog cov hlau lead, tin, cadmium, thiab antimony stabilizers, thiab tsis muaj kuab paug sulfur. Nws yog qhov tsim nyog rau cov chaw tsim khoom uas twb tau siv cov tshuaj stabilizers ntsev txhuas los hloov cov khoom tsis muaj tshuaj lom thiab cov khoom zoo rau ib puag ncig.
4. Lwm qhov zoo dua ntawm cov calcium zinc stabilizers yog lawv qhov kev tiv thaiv huab cua zoo, thiab cov khoom tsim los ntawm cov calcium zinc composite stabilizers tsim nyog yuav tsis muaj kev hloov pauv.
Kev siv cov tshuaj ua kom cov ntsev ua kom ruaj khov tau maj mam txo qis vim lawv cov tshuaj lom. Nws cov yam ntxwv yog raws li nram no:
1. Lom.
2. Tsis siv tau rau cov khoom pob tshab.
3. Kev rwb thaiv hluav taws xob zoo thiab tiv taus huab cua;
4. Tus nqi qis;
5. Kev ua haujlwm zoo uas tsim nyog rau ntau yam txheej txheem;
