Sehatsetsi sa letsoai la lead sa PVC ke sesebelisoa se atisang ho sebelisoa sa ho tsitsisa mocheso ha ho sebetsoa polyvinyl chloride (PVC). Haholo-holo se ntlafatsa botsitso ba mocheso ba thepa ka ho tšoara hydrogen chloride (HCl), 'me se na le melemo e ikhethang ea ho thibela motlakase le litšenyehelo. Libaka tsa eona tsa mantlha tsa ts'ebeliso li kenyelletsa:
Maemo a mantlha a kopo:
1. Lihlahisoa tse thata tsa PVC
Tse kang liphaephe, lipoleiti, liprofaele, jj., tse loketseng haholo-holo lihlahisoa tse sa bonahaleng (tse kang li-sheath tsa terata le tsa cable, liphaephe tsa ho haha tsa metsi). Li-stabilizer tsa letsoai la loto li ka thibela ho senyeha ha mocheso oa PVC ka katleho nakong ea ts'ebetso le ho atolosa bophelo ba ts'ebeletso ea lihlahisoa.
2. Indasteri ea terata le ea likhoele
Ka lebaka la thepa ea eona e ntle ea ho thibela motlakase, li-stabilizer tsa letsoai la loto li sebelisoa haholo tlhahisong ea thepa ea thapo ea PVC.
Melemo ea tekheniki:
Ntlafatso ea matsoai a loto a kopantsoeng: Matsoai a loto a kopanngoa le mafura ka theknoloji ea karabelo ea symbiotic ho etsa lihlahisoa tse se nang lerōle, ho fokotsa tšilafalo ea lerōle le ho ntlafatsa ho qhalana ha tsona.
Katleho ea litšenyehelo: Tšepe e ngata, bokhoni bo matla ba ho monya HCl, le ho ikamahanya le maemo a mocheso ka bophara, e loketse tlhahiso ea indasteri e kholo.
Meeli le Mekhoa e Meng
Bothata ba chefo: Chefo ea loto e nang le tšepe e boima e fokotsa ts'ebeliso ea eona linthong tse amanang le lijo, lisebelisoa tsa bongaka le mafapheng a mang.
Phetolo ea tikoloho: Ka tlhoko e ntseng e eketseha ea tšireletso ea tikoloho, lihlahisoa tse nang le chefo e tlase tse kang li-calcium zinc composite stabilizers le organotin li ntse li nkela letsoai la loto sebaka butle-butle.
Kakaretso: Li-stabilizer tsa letsoai la loto la PVC li ntse li na le tlholisano masimong a indasteri a setso, empa boholo ba ts'ebeliso ea tsona bo hloka ho leka-lekana le melaoana ea tikoloho. Theknoloji ea letsoai la loto le kopaneng e bolokile boemo ba eona ba 'maraka maemong a itseng ka ho ntlafatsa mekhoa le lits'ebetso.
