Ukuqhathaniswa Komehluko Oyinhloko Phakathi Kweziqinisi Ze-PVC Calcium Zinc kanye Neziqinisi Ze-Lead Salt:
1, Ubungane bemvelo kanye nobuthi
1. Isiqinisi se-calcium zinc
Ayinazo nhlobo izinsimbi ezisindayo ezifana ne-lead ne-cadmium, ngokuhambisana nezindinganiso zemvelo ze-EU RoHS/REACH;
Iqinisekiswe yi-FDA, ifanelekela imikhakha ebucayi yokuphepha njengokupakisha ukudla kanye namadivayisi ezokwelapha.
2. Isiqinisi sikasawoti oholayo
Njengoba iqukethe i-lead yensimbi esindayo, ukungcola kothuli olunobuthi kukhiqizwa ngesikhathi sokucubungula, futhi ukuchayeka isikhathi eside kungalimaza impilo yabantu;
Imikhiqizo elahliwe ingabangela kalula ukungcola kwenhlabathi namanzi.
2, Indlela yokuqina kwe-Thermal
1. Isiqinisi se-calcium zinc
Ngokusebenzisa indlela yokulungisa enezingqimba ezimbili: insipho ye-zinc ithatha indawo yama-athomu e-chlorine angazinzile, insipho ye-calcium iphinda ivuselele insipho ye-zinc ukuze kwandiswe isikhathi sokuqina;
Kuyadingeka ukusebenzisa ama-synergists afana ne-β – diketone kanye ne-hydrotalcite ukuze kuthuthukiswe ukuzinza (ngenani elengeziwe elingu-0.3% -2%).
2. Isiqinisi sikasawoti oholayo
Ukwakha ngqo inkimbinkimbi ngama-molecule e-PVC, kuvimbela ngempumelelo ukusabela kwe-HCl removal chain;
Ingxenye eyodwa ingafinyelela ukuzinza kokushisa kwesikhathi eside ngaphandle kwesidingo sezinhlelo eziyinkimbinkimbi zokuvumelanisa.
3, Ukusebenza kokucubungula
| Izinto zokuqhathanisa | Isiqinisi se-calcium zinc | 铅盐稳定剂 |
| Ukugcotshwa | Ukulawulwa okunembile kwesilinganiso samafutha kuyadingeka (inani eliningi kakhulu livame ukuna) | Iza nezici zokugcoba kanye nefasitela elibanzi lokucubungula |
| ukulawula umbala | Umkhiqizo uthambekele ekukhanyeni okuluhlaza okwesibhakabhaka futhi udinga ukulungiswa ngokufaka i-toner | Ukuqina kombala okuphezulu kanye nokushintshashintsha okuncane phakathi kwamaqoqo |
| Ukugeleza kokuncibilika | Nciphisa izinga lokushisa lokwenza ipulasitiki ngo-5-10 ℃ | Akunamthelela omkhulu ekuqineni kokuncibilika |
4, ukulinganiselwa kwesimo sesicelo
1. Isiqinisi se-calcium zinc
Imikhiqizo ecacile idinga ukwengeza i-hypophosphite (0.5%) ukuze kuthuthukiswe ukucaca;
Izinhlelo zokugcwalisa kakhulu (i-calcium carbonate>30phr) zivame ukuba nezinkinga zesithwathwa.
2. Isiqinisi sikasawoti oholayo
◉ Kusebenza kuphela emikhiqizweni engacacile (njengemibhobho namaphrofayili);
Indawo equkethe isibabule enyakatho ingabangela kalula ukuthi ubuso bemikhiqizo bube yi-sulfide futhi bube mnyama.
5, umehluko kwezomnotho
Ubuningi be-calcium zinc stabilizer buphansi ngo-40%, okungandisa inani le-filler eyengeziwe futhi kunciphise izindleko;
Intengo yeyunithi yeziqinisi zikasawoti we-lead iphansi, kodwa izindleko ezengeziwe zokwelashwa kwensimbi esindayo zidinga ukuthwalwa;
Ngokuqhathanisa okunezilinganiso eziningi, kungabonakala ukuthi iziqinisi ze-calcium zinc zinenzuzo enkulu ekuzivumelaniseni nemvelo, kuyilapho iziqinisi ze-lead salt zisagcina inani elithile lokusetshenziswa ekubhekaneni nokucubungula kanye nokulawula izindleko.
