Yiziphi izici ze-calcium zinc stabilizers ezinobungani bemvelo:

I-calcium zinc stabilizers yi-nitric oxide synthase eyakhiwe ngosawoti ophilayo we-calcium zinc, i-hypophosphite esters, i-polyether polyols, ama-antioxidants, nezinyibilikisi eziphilayo. Iziqinisi ze-calcium zinc zinokuhambisana okuhle nama-epoxy resins kanye nama-thickeners, ukukhanya okuhle, futhi akulula ukushona phansi. Asetshenziswa ngamanani amancane futhi kulula ukuwasebenzisa. Kodwa-ke, banokungalungi kokumanzisa okubuthakathaka, ukunciphisa indawo yokuthambisa yomkhiqizo, futhi ukugcinwa kwesikhathi eside kungase kubangele ukukhula kwesikhunta. I-Solid state composite calcium zinc soap stabilizers ikakhulukazi yakhiwe insipho ye-polyether, elandelwa yinsipho ye-lauric acid kanye nensipho enamafutha acid. Isici se-calcium zinc stabilizers ukumanzisa okuhle, okunganciphisi iphuzu lokuthambisa lemikhiqizo eqinile ye-PVC, futhi ifanele ukukhiqizwa nokucutshungulwa kwamapayipi e-PVC aqinile kanye namaphrofayili e-PVC. Imikhiqizo ekhiqizwe futhi yacutshungulwa kubuchwepheshe be-microemulsion ingaqeda amaphutha okukhulunywe ngawo ngenhla.

Sigxila kakhulu ezicini ezimbili zokwenza ngcono: ukuze kuthuthukiswe umbala ekuqaleni, inani elanele lensipho ye-zinc liyengezwa, futhi ama-antioxidants asetshenziselwa ukuphatha okungenangozi i-zinc chloride, eba yinhlanganisela ye-zinc ephezulu futhi inciphise inani. insipho ye-zinc eyengezwe ukucindezela ukuvutha kwe-zinc.

Ukusetshenziswa kwama-preservatives ukuguqula inqubo yombala yangaphambilini kubangela inhlanganisela ye-zinc ephansi, esetshenziswa kabanzi hhayi kuphela emikhiqizweni ethambile kodwa futhi nasekuzinzeni kokushisa nokucaca kwe-calcium zinc stabilizers. Iphinde yasetshenziswa ngempumelelo ekukhiqizeni nasekucutshungulweni kwemikhiqizo eqinile, ukuze kugcinwe kangcono uhlelo lokuphatha i-calcium/zinc ngenkathi kuvimbela ukufakwa kombala kusenesikhathi futhi kucindezela ukushiswa kwe-zinc.

Ngokuvamile, usawoti oholayo unamathele kuphela ebusweni bezinhlayiya ze-PVC, futhi umphumela wabo ulingana nokuvimbela ukubopha phakathi kwezinhlayiya ze-PVC, ukubambezeleka kakhulu kwe-plasticization, ukunciphisa ukungqubuzana phakathi kwezinhlayiya ze-PVC, nokunciphisa umphumela wokusika ngaphakathi kwe-PVC. Imishini yokukhiqiza inomthwalo ophansi, futhi inani likasawoti omthofu elisetshenziswayo liphezulu. Ukuqina kwezinhlayiya zikasawoti omthofu, umphumela wesibili ubaluleke kakhulu. Imikhiqizo yendabuko eluhlaza kanye nemvelo enobungani njenge-calcium zinc stabilizer ine-electronegativity eqinile ngesikhathi senqubo yokwenza ipulasitiki. Amaqembu asebenzayo asebenzayo anokutheleleka okuthile okunamaphoyinti okuxhuma angaphansi kwe-PVC epoxy resin, akhiqiza isibopho esinamandla ebhondi aqine ngokwedlulele, elenza buthaka noma lisuse ukukhangwa kwamabhondi e-ion ezendlalelo ezihlukahlukene ze-PVC. Leli iketango lokuvula le-PVC elihlanganiswe elinye nelinye, okwenza kube lula ukusabalalisa kwangaphandle. Isakhiwo samangqamuzana samaqembu asebenzayo senza kube lula ukuthi i-PVC isakazeke. Umngcele ophakathi usiza ukufakwa kwepulasitiki kwe-PVC epoxy resin.
