Umehluko phakathi kwe-calcium zinc stabilizer ne-lead stabilizer

I-calcium zinc stabilizer kanye ne-composite lead salt stabilizer ibhekisela kuzinzinzisi ezishisayo ze-PVC ezidlala indima ekuzinzeni okushisayo ekukhiqizeni imikhiqizo ye-PVC. Umehluko phakathi kwalokhu okubili umi kanje:

I-Calcium zinc thermal stabilizers ihlangabezana nezidingo zemvelo futhi njengamanje isetshenziswa kabanzi. Izici zayo zihlanganisa izici ezilandelayo:

1. Isici esibaluleke kakhulu se-calcium zinc stabilizers ukuthi asetshenziswa kukho kokubili ukwakheka kwemikhiqizo esobala kanye ne-opaque ezintweni zokwakha zamakhemikhali, ngokusebenza okuqinile.

2. Intengo iphansi kunethayela eliphilayo.

3. Inokuhambisana kahle nokusebenzelana kahle nomthofu, ithini, i-cadmium, neziqinisa i-antimoni, futhi akukho ukungcola kwe-sulfide. Ilungele abakhiqizi asebevele basebenzise izinzamisi zikasawoti oholayo ukuze bathathe indawo yemikhiqizo engeyona enobuthi futhi ehambisana nemvelo.

4. Enye inzuzo ephawulekayo ye-calcium zinc stabilizers ukumelana nesimo sezulu esihle, futhi imikhiqizo ekhiqizwe nge-calcium zinc composite stabilizers efanelekayo ngeke ikhiqize ukuguga.

Iziqinisi zikasawoti omthofu zinezigaba ezimbili ezinkulu zamamonomers nezinhlanganisela, futhi izinzamisi zikasawoti omthofu zisetshenziswa ngokuyisisekelo njengesizinzisi esikhulu eChina. I-composite lead salt heat stabilizer isebenzisa ubuchwepheshe bokusabela kwe-symbiotic ukuxuba usawoti abathathu, osawoti ababili kanye nensipho yensimbi ohlelweni lokusabela ngosayizi wokuqala wokusanhlamvu wemvelo kanye nezinto zokugcoba ezihlukahlukene ukuze kuqinisekiswe ukuhlakazeka okugcwele kwesizinzisi sokushisa ohlelweni lwe-PVC, futhi ngesikhathi esifanayo, ngenxa yokubambisana ne-lubricant ukwakha ifomu le-granular, iphinde igweme ubuthi obubangelwa uthuli lomthofu. Iziqinisi zikasawoti oholayo eziyinhlanganisela ziqukethe kokubili isiqinisi sokushisa nezinto zokuthambisa ezidingekayo ukuze kucutshungulwe futhi zibizwa ngokuthi izinzinzisi zokushisa ezigcwele iphakheji.Izimpawu zakhona zimi kanje:

1. Okunobuthi.

2. Ayikwazi ukusetshenziselwa imikhiqizo esobala.

3. Ukufakwa kahle kukagesi nokumelana nesimo sezulu;

4. Intengo ephansi;

5. Ukusebenza okuhle kokucubungula okulungele izinqubo ezahlukahlukene;
