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

1, Indlela yokusebenza
Isiqinisi se-calcium zinc: sivimbela ukubola kwe-PVC ngomphumela wokubambisana kwensipho ye-calcium nensipho ye-zinc, kuyilapho simunca igesi ye-HCl ekhiqizwa ukubola kwe-PVC. Ukuqina kwayo kuvela emphumeleni ohlanganisiwe wezingxenye eziningi (njenge-rare earths, i-hydrotalcite, njll.), okungavimbela ukubola kwe-catalytic kwe-PVC ngama-ion e-zinc.
Isiqinisi sikasawoti oholayo: ukuthembela ku-asidi enamandla ka-Lewis kasawoti oholayo ukuze kuncishiswe i-HCl, kanye nokuvimba ukusabela kokubola kwe-PVC ngokususa ama-athomu e-chlorine angazinzile.
2, Ukuzinza kanye nobungane bemvelo
Ukuzinza:
Iziqinisi zikasawoti we-lead zinokuqina okungcono kokushisa, zinombala wokuqala ovelele, ukuthambisa, kanye nokumelana nesimo sezulu isikhathi eside.
Ukuqina kokuqala kweziqinisi ze-calcium zinc kubuthakathaka, kodwa imikhiqizo ehlanganisiwe efana ne-rare earth calcium zinc ithuthukisa kakhulu ukusebenza ngemiphumela yokusebenzisana, isondela ezingeni likasawoti we-lead.
Ubungane nemvelo:
Usawoti we-lead uqukethe i-lead yensimbi esindayo, ebangela ukungcola kwemvelo kanye nezingozi zempilo yabantu, futhi ayihambisani nemithethonqubo yemvelo efana ne-EU RoHS.
Iziqinisi ze-calcium zinc azinazo izinsimbi ezisindayo, ziyahlangabezana nezidingo zemvelo, futhi ziyakwazi ukumelana nokungcola kwesibabule (njengokungashintshi zibe mnyama ezindaweni ezinemvula ye-acid enyakatho).
3, Izinkambu Zohlelo Lokusebenza
Isiqinisi sikasawoti oholayo: Ngenxa yezindleko zaso eziphansi kanye nokuvikela okuhle kukagesi, sasisetshenziswa kabanzi emikhakheni yezimboni njengezintambo namapayipi, kodwa kancane kancane saphela.
Isiqinisi se-calcium zinc: silungele amasimu azwela imvelo njengokupakisha ukudla, amadivayisi ezokwelapha, amaphrofayili eminyango namafasitela, futhi akukho bungozi bokungcola okuhlukahlukene lapho kushintshwa usawoti we-lead kanye neziqinisi ze-organotin.
4, Eminye imehluko
Ubuningi kanye Nezindleko: Izithambisi ze-calcium zinc zinobukhulu obuphansi (cishe ngo-40% ngaphansi kukasawoti we-lead), okungandisa inani le-calcium carbonate elisetshenziswa ukunciphisa izindleko.
Ukugcotshwa: Usawoti we-lead unamafutha angcono, kuyilapho i-calcium ne-zinc zithembele ezintweni zokugcoba ezisizayo ukulawula inqubo yokwenza ipulasitiki.
Amandla okulwa nokusha kwe-zinc: Iziqinisi ze-calcium zinc zidinga ukungezwa kwezingxenye ezisizayo njenge-polyols kanye ne-phosphites ukuvimbela ukuwohloka kwe-zinc chloride.
fingqa
Nakuba iziqinisi zikasawoti we-lead zisebenza kahle kakhulu, ubungane bazo nemvelo abubuhle. Iziqinisi zikasawoti we-calcium ziye zanciphisa kancane kancane igebe lokusebenza ngokuthuthuka kwezobuchwepheshe (njengezinhlanganisela zomhlaba ezingavamile) futhi zaba ezinye izindlela ezivamile zemvelo.
