Kusiyana pakati pa calcium zinc stabilizer ndi composite lead salt stabilizer:

Cholimbitsa calcium zinc ndi cholimbitsa mchere wa lead wopangidwa ndi zinthu zosiyanasiyana zimatanthauza zolimbitsa kutentha za PVC, zomwe zimathandiza kuti kutentha kukhazikike pakupanga zinthu za PVC. Kusiyana pakati pa ziwirizi ndi motere:
Zolimbitsa kutentha za calcium zinc zimakwaniritsa zofunikira zachilengedwe ndipo pakadali pano zimagwiritsidwa ntchito kwambiri. Makhalidwe ake ndi awa:
1. Chinthu chofunika kwambiri cha calcium zinc stabilizers ndichakuti amagwiritsidwa ntchito popanga zinthu zowonekera komanso zosawoneka bwino mu zipangizo zomangira mankhwala, zomwe zimagwiritsidwa ntchito kwambiri.
2. Mtengo wake ndi wotsika kuposa wa organotin.
3. Imagwirizana bwino ndi zinthu zokhazikika monga lead, tin, cadmium, ndi antimony, ndipo palibe kuipitsidwa kwa sulfure. Ndi yoyenera opanga omwe agwiritsa ntchito kale zinthu zokhazikika monga lead salt m'malo mwa zinthu zopanda poizoni komanso zoteteza chilengedwe.
4. Ubwino wina waukulu wa zinthu zokhazikika za calcium zinc ndi kukana kwawo nyengo, ndipo zinthu zopangidwa ndi zinthu zokhazikika za calcium zinc sizidzasintha mtundu.
Kugwiritsa ntchito zinthu zolimbitsa mchere wa lead kwachepa pang'onopang'ono chifukwa cha poizoni wake. Makhalidwe ake ndi awa:
1. Woopsa.
2. Sizingagwiritsidwe ntchito pazinthu zowonekera bwino.
3. Kuteteza magetsi bwino komanso kukana nyengo;
4. Mtengo wotsika;
5. Kugwira ntchito bwino kwa processing koyenera njira zosiyanasiyana;
