Umahluko phakathi kwe-calcium zinc stabilizer kunye ne-lead salt stabilizer

1, Indlela yokusebenza
Isiqinisi se-calcium zinc: sithintela ukubola kwe-PVC ngesiphumo sokusebenzisana kwesepha ye-calcium kunye nesepha ye-zinc, ngelixa sifunxa igesi ye-HCl eveliswa kukubola kwe-PVC. Ukuzinza kwayo kuvela kwisiphumo esidibeneyo sezinto ezininzi (ezifana ne-rare earths, i-hydrotalcite, njl.njl.), enokuthintela ukubola kwe-catalytic ye-PVC yi-zinc ions.
Isiqinisi setyuwa yelothe: ukuxhomekeka kwi-asidi enamandla yeLewis yetyuwa yelothe ukuze kuncitshiswe i-HCl, kunye nokuthintela impendulo yokubola kwetyathanga le-PVC ngokususa iiathom ze-chlorine ezingazinzanga.
2, Uzinzo kunye nobuhlobo nokusingqongileyo
Uzinzo:
Iziqinisi zetyuwa yelothe zinozinzo olungcono lobushushu, zinombala ogqwesileyo wokuqala, ukuthambisa, kunye nokumelana nemozulu ixesha elide.
Uzinzo lwasekuqaleni lwe-calcium zinc stabilizers lubuthathaka, kodwa iimveliso ezidityanisiweyo ezifana ne-rare earth calcium zinc ziphucula kakhulu ukusebenza ngokusebenzisa iziphumo ze-synergistic, zisondela kwinqanaba leetyuwa ze-lead.
Ubuhlobo nokusingqongileyo:
Iityuwa ze-lead ziqulathe i-lead yesinyithi esinzima, ebeka ungcoliseko lokusingqongileyo kunye nemingcipheko kwimpilo yabantu, kwaye ayithobeli imithetho yokusingqongileyo efana ne-EU RoHS.
Iziqinisi ze-calcium zinc azinazo iintsimbi ezinzima, azihlangabezani neemfuno zokusingqongileyo, kwaye ziyakwazi ukumelana nongcoliseko lwesalfure (njengokungaguquki kube mnyama kwiindawo ezinemvula ye-asidi emantla).
3, Amasimi eSicelo
Isiqinisi setyuwa yelead: Ngenxa yexabiso layo eliphantsi kunye nobushushu obuhle bombane, yayisetyenziswa kakhulu kwiindawo zoshishino ezifana neentambo kunye nemibhobho, kodwa kancinci kancinci yaphela.
Isiqinisi se-calcium zinc: sifanelekile kwiindawo ezinobuthathaka kokusingqongileyo ezifana nokupakishwa kokutya, izixhobo zonyango, iiprofayili zomnyango neefestile, kwaye akukho mngcipheko wongcoliseko oludibeneyo xa utshintshana neetyuwa ze-lead kunye neziqinisi ze-organotin.
4, Ezinye iiyantlukwano
Ubuninzi kunye neendleko: Iziqinisi ze-calcium zinc zinobunzima obuphantsi (malunga ne-40% ngaphantsi kuneetyuwa ze-lead), nto leyo enokunyusa ubungakanani be-calcium carbonate esetyenziselwa ukunciphisa iindleko.
Ukuthambisa: Iityuwa zelothe zinokugcoba okungcono, ngelixa i-calcium kunye ne-zinc zixhomekeke kwii-lubricants ezincedisayo ukulawula inkqubo yokwenza iplastiki ibe nkulu.
Amandla okutsha kwe-zinc: Iziqinisi ze-calcium zinc zifuna ukongezwa kwezinto ezincedisayo ezifana nee-polyols kunye nee-phosphites ukuthintela ukubola kwe-zinc chloride.
shwankathela
Nangona izinto ezigcina ityuwa yelothe zisebenza kakuhle kakhulu, ububele bazo kokusingqongileyo abunamsebenzi. Izinto ezigcina icalcium zinc ziye zanciphisa kancinci kancinci umsantsa wokusebenza ngokuphucula ubuchwepheshe (njengezinto ezidityanisiweyo zomhlaba ongaqhelekanga) zaza zaba zezona ndlela ziphambili zokusingqongileyo.
