Umehluko phakathi kwe-calcium zinc stabilizer kanye ne-composite lead salt stabilizer:

Isiqinisi se-calcium zinc kanye nesiqinisi se-composite lead salt stabilizer sibhekisela kuziqinisi zokushisa ze-PVC, ezidlala indima ekuzinzeni kokushisa ekukhiqizweni komkhiqizo we-PVC. Umehluko phakathi kwalokhu okubili ungokulandelayo:
Iziqinisi zokushisa ze-calcium zinc zihlangabezana nezidingo zemvelo futhi okwamanje zisetshenziswa kabanzi. Izici zazo zifaka phakathi izici ezilandelayo:
1. Isici esibaluleke kakhulu seziqinisi ze-calcium zinc ukuthi zisetshenziswa kokubili ekwakhiweni komkhiqizo okusobala nokungabonakali ezintweni zokwakha zamakhemikhali, futhi zisebenza kahle kakhulu.
2. Intengo iphansi kuneye-organotin.
3. Ihambisana kahle futhi ihambisana kahle neziqinisi ze-lead, i-tin, i-cadmium, kanye ne-antimony, futhi akukho ukungcoliswa kwe-sulfur. Ifanele abakhiqizi asebevele besebenzise iziqinisi ze-lead salt ukuze bathathe indawo yemikhiqizo engenabo ubuthi futhi enobungani nemvelo.
4. Enye inzuzo ebalulekile yeziqinisi ze-calcium zinc ukumelana kwazo nesimo sezulu esihle, futhi imikhiqizo ekhiqizwe ngeziqinisi ze-calcium zinc ezihlanganisiwe ezifanelekile ngeke ishintshe umbala.
Ukusetshenziswa kweziqinisi zikasawoti we-lead kuye kwehla kancane kancane ngenxa yobuthi bazo. Izici zalo zimi kanje:
1. Ubuthi.
2. Ayikwazi ukusetshenziselwa imikhiqizo esobala.
3. Ukuvikela okuhle kukagesi kanye nokumelana nesimo sezulu;
4. Intengo ephansi;
5. Ukusebenza kahle kokucubungula okufanele izinqubo ezahlukahlukene;
