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

Isiqinisi se-calcium zinc kanye nesiqinisi se-composite lead salt stabilizer sibhekisela kuziqinisi ze-PVC ezishisayo ezidlala indima ekuzinzeni kokushisa ekukhiqizweni kwemikhiqizo ye-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 kune-tin yemvelo.

3. Ihambisana kahle futhi ihambisana kahle neziqinisi ze-lead, i-tin, i-cadmium, kanye ne-antimony, futhi akukho ukungcoliswa kwe-sulfide. Ifanele abakhiqizi asebevele basebenzisa 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 idale ukushintsha kombala.

Iziqinisi zikasawoti we-lead zinezigaba ezimbili ezinkulu zama-monomers nama-composites, kanti iziqinisi zikasawoti we-lead zisetshenziswa ngokuyinhloko njengesiqinisi esiyinhloko eShayina. Isiqinisi sikasawoti we-lead esihlanganisiwe sisebenzisa ubuchwepheshe bokusabela kwe-symbiotic ukuxuba usawoti abathathu, usawoti ababili kanye nensipho yensimbi ohlelweni lokusabela nosayizi wokuqala wezinhlamvu zemvelo kanye nokugcoba okuhlukahlukene ukuqinisekisa ukusabalala okugcwele kwesiqinisi sikasawoti ohlelweni lwe-PVC, futhi ngesikhathi esifanayo, ngenxa yokuhlangana nesikhisini ukuze kwakhiwe ifomu eliyi-granular, futhi sigwema ubuthi obubangelwa uthuli lwe-lead. Iziqinisi zikasawoti we-lead ezihlanganisiwe ziqukethe kokubili isiqinisi sikasawoti kanye nezingxenye zokugcoba ezidingekayo ekucutshungulweni futhi zibizwa ngokuthi iziqinisi zikasawoti zephakheji ephelele. Izici zazo yilezi ezilandelayo:

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;
