Uthelekiso loMmahluko oPhambili phakathi kwePVC Calcium Zinc Stabilizers kunye neLead Salt Stabilizers:
1, Ubuhlobo nokusingqongileyo kunye nobutyhefu
1. Isiqinisi se-calcium zinc
Ayinazo kwaphela iintsimbi ezinzima ezifana ne-lead kunye ne-cadmium, ngokuhambelana nemigangatho yokusingqongileyo ye-EU RoHS/REACH;
Iqinisekisiwe yi-FDA, ifanelekile kwiindawo ezinobuzaza bokhuseleko ezifana nokupakishwa kokutya kunye nezixhobo zonyango.
2. Isiqinisi setyuwa yelothe
Iqulethe i-heavy metal lead, ungcoliseko lothuli olunetyhefu luyavela ngexesha lokucubungula, kwaye ukuvezwa ixesha elide kungonakalisa impilo yabantu;
Iimveliso ezilahliweyo zinokubangela ungcoliseko lomhlaba namanzi ngokulula.
2, indlela yozinzo lweThermal
1. Isiqinisi se-calcium zinc
Ngokusebenzisa indlela yokulungisa iileya ezimbini: isepha ye-zinc ithatha indawo yeeathom ze-chlorine ezingazinzanga, isepha ye-calcium iphinda ivuselele isepha ye-zinc ukuze yandise ixesha lozinzo;
Kuyimfuneko ukusebenzisa ii-synergists ezifana ne-β – diketone kunye ne-hydrotalcite ukuphucula uzinzo (kunye nesixa esongeziweyo se-0.3% -2%).
2. Isiqinisi setyuwa yelothe
Ukwenza ngokuthe ngqo i-complex ngee-molecule ze-PVC, ukuthintela ngokufanelekileyo i-HCl removal chain reaction;
Icandelo elinye linokufikelela kuzinzo lobushushu bexesha elide ngaphandle kwesidingo seenkqubo ezintsonkothileyo zentsebenziswano.
3, Ukusebenza kokucubungula
| Izinto zokuthelekisa | Isiqinisi se-calcium zinc | 铅盐稳定剂 |
| Ukutyeba | Ulawulo oluchanekileyo lomlinganiselo wezithambiso luyafuneka (ubuninzi obugqithisileyo bunokuna) | Iza neempawu zokuthambisa kunye nefestile ebanzi yokucubungula |
| ulawulo lombala | Le mveliso ithambekele ekubeni nombala oluhlaza okwesibhakabhaka kwaye kufuneka ilungiswe ngokongeza i-toner | Uzinzo oluphezulu lombala kunye nokuguquguquka okuncinci phakathi kweebhetshi |
| Ukunyibilika kokuhamba kwamanzi | Nciphisa ubushushu bokwenza iplastiki ibe yi-5-10 ℃ | Ayinampembelelo ingako kwi-viscosity ye-melt |
4, imida yesimo sesicelo
1. Isiqinisi se-calcium zinc
Iimveliso ezicacileyo kufuneka zongeze i-hypophosphite (0.5%) ukuphucula ukucaca;
Iinkqubo zokuzalisa eziphezulu (icalcium carbonate engaphezulu kwama-30phr) zinokuba neengxaki zeqhwa.
2. Isiqinisi setyuwa yelothe
◉ Isebenza kuphela kwiimveliso ezingacacanga (ezifana nemibhobho kunye neeprofayili);
Indawo eneesulfure emantla inokubangela ukuba umphezulu weemveliso ube yi-sulfide kwaye ube mnyama.
5, umahluko kwezoqoqosho
Uxinano lwe-calcium zinc stabilizer luphantsi ngama-40%, nto leyo enokunyusa ubungakanani be-filler eyongeziweyo kwaye inciphise iindleko;
Ixabiso leyunithi yeziqinisi zetyuwa yelothe liphantsi, kodwa iindleko ezongezelelweyo zonyango lwesinyithi esinzima kufuneka zithwalwe;
Ngokuthelekisa izinto ezininzi, kunokubonwa ukuba iziqinisi ze-calcium zinc zinenzuzo enkulu ekuzivumelaniseni nokusingqongileyo, ngelixa iziqinisi zetyuwa ye-lead zisagcina ixabiso elithile lokusetyenziswa ekunyamezeleni ukucubungula kunye nokulawula iindleko.
