Emkhiqizweni Wesikhumba Wokwenziwa,ukushisa PVC stabilizersidlala indima ebalulekile.Icindezela ngokuphumelelayo ukwenzeka kwesenzakalo sokubola okushisayo, kuyilapho ilawula ngokunembile izinga lokusabela ukuze kuqinisekiswe ukuzinza kwesakhiwo se-polymer yamangqamuzana, ngaleyo ndlela iqinisekise ukuqhubeka kahle kwayo yonke inqubo yokukhiqiza.
(1)I-Barium cadmium zinc i-thermal stabilizer
Enqubweni yokuqala ye-calendering, i-barium cadmium zinc heat stabilizers yayivame ukusetshenziswa. Ama-salts e-Barium angaqinisekisa ukuzinza kwezinto ngesikhathi sokucubungula okuphezulu kokushisa, usawoti we-cadmium udlala indima yokuzinza phakathi nokucubungula, futhi usawoti we-zinc ungabamba ngokushesha i-hydrogen chloride ekhiqizwa ukuwohloka kwe-PVC ekuqaleni.
Kodwa-ke, ngenxa yobuthi be-cadmium, ukusetshenziswa kwalezi zinzinzisi kube ngaphansi kwemikhawulo eminingi njengoba izidingo zemvelo ziya ngokuya ziba namandla.
I-Barium zinc stabilizers, njengohlobo olubalulekile lwe-stabilizer yokushisa, isetshenziswa kabanzi ekukhiqizeni isikhumba sokwenziwa.Enqubweni yokugqoka, i-barium zinc stabilizer yenza kahle. Enqubweni ye-plasticization kahhavini, ingavimbela ukumbozwa ukuthi kungabi phuzi futhi kube brittle ngenxa yokushisa okuphezulu, okwenza umkhiqizo wesikhumba wokwenziwa oqediwe ugqame futhi uhlale isikhathi eside ngombala.
(3)I-Calcium Zinc composite heat stabilizer
Namuhla, i-calcium zinc composite heat stabilizers isiyinsakavukela. Enqubweni ye-calendering, ingakwazi ukugcina ukuzinza kwezinto ezingaphansi kokuxubana nokugoqa okuphezulu. Usawoti we-calcium unomthwalo wemfanelo wokuzinza okushisayo kwesikhathi eside, kuyilapho usawoti we-zinc uthola ukwelashwa okufika ngesikhathi kokubola kokuqala okushisayo. Izithasiselo ze-organic ziphinde zithuthukise umphumela wokuzinza, okuholela ekugqileni okufanayo nokusebenza kahle kwesikhumba sokwenziwa.
Ngaphezu kwalokho, ngenxa yezici zayo ezihambisana nemvelo nezingenabo ubuthi, ifaneleka ngokukhethekile izinkambu ezinezidingo eziphakeme zemvelo njengamathoyizi ezingane kanye nesikhumba sokwenziwa sokupakisha ukudla.
I-TopJoy Chemical igxile ocwaningweni nasekukhiqizweni kwezinzinzisi ze-PVC, futhi imikhiqizo yayo iye yatshalwa ngokujulile emkhakheni wesikhumba sokwenziwa iminyaka eminingi. Ngokuzinza okuhle kakhulu kokushisa, ukuhambisana okuhle, nokumelana nesimo sezulu okuvelele, ikhwalithi yesikhumba sokwenziwa iqinisekiswa ngempumelelo, futhi yenza kahle kukho kokubili ukuqina kombala kanye nezakhiwo ezibonakalayo, ngaleyo ndlela izuza ukwethenjwa kwamakhasimende asekhaya nawangaphandle.
