Mesebetsi e meholo ea titanium dioxide bakeng sa liphaephe ke efe?

1, Mesebetsi ea mantlha
Ntlafatsa ho hanyetsa boemo ba leholimo le ho hanyetsa botsofali: titanium dioxide (TiO2) e ka liehisa ts'ebetso ea botsofali ba liphaephe (joalo ka liphaephe tsa PVC le PE) tikolohong ea kantle, ea thibela ho ba mosehla, ho fifala le ho qhibiliha ha bokaholimo, 'me ea eketsa bophelo ba ts'ebeletso haholo ka ho monya leseli la ultraviolet le ho thibela karabelo ea photochemical. Rutile titanium dioxide e na le bokhoni bo matla ba ho sireletsa UV ka lebaka la kalafo ea ho roala (joalo ka zirconia/alumina).
Ntlafatsa sekoahelo le bosweu: Thepa e phahameng ea refractive index e lumella titanium dioxide ho hasanya leseli le bonahalang, e koahela 'mala oa motheo oa substrate ea phaephe (joalo ka 'mala o mosehla o bobebe oa motheo oa PVC), e fa sehlahisoa bosweu bo phahameng, 'mala o ts'oanang, le ponahalo e khanyang. Mohlala oa molumo oa motheo oa karolo e putsoa o ka ntlafatsa bosweu ba pono.
Ho ntlafatsa ts'ebetso ea ts'ebetso le botsitso: Ho monya oli hanyane (≤ 23g/100g) le mekhoa ea kalafo ea bokaholimo ba tlhaho (joalo ka ho eketsa leseli TR-36) ho ntlafatsa ho qhalana ha titanium dioxide ka har'a polasetiki e qhibilihang, ho fokotsa tšebeliso ea matla a tlhahiso, le ho qoba liphoso tse kang masoba le matšoao a phallo holim'a liphaephe.
2, Litlhoko tse khethehileng tsa kopo
Ho ikamahanya le maemo a leholimo: Liphaephe tsa kantle li tlameha ho sebelisa rutile titanium dioxide (joalo ka SR-236, R-838), eo sekoahelo sa eona se ka hanelang ho senyeha ha resin ho bakoang ke catalysis ea UV; Mofuta oa titanium o bohale o sekametse ho potlakisa botsofali ba liphaephe ka lebaka la khanyetso e mpe ea boemo ba leholimo.
Molumo oa 'mala le taolo ea tšepe e boima: Titanium dioxide ea karolo e putsoa (joalo ka R-248) e ka loantša molumo o mosehla oa tlhaho oa liphaephe tsa PVC le ho ntlafatsa ponahalo ea tsona e hloekileng; Ela hloko litaba tsa tšepe e boima (joalo ka chromium le loto) tsa titanium dioxide liphaepheng tse amanang le metsi ho qoba ho silafatsa boleng ba metsi.
Ho lumellana ha tlatsetso: Liphaephe tsa PVC tse nang le li-stabilizer tsa letsoai la loto li lokela ho khethoa ka mehlala e loketseng ho thibela karabelo e mpe lipakeng tsa titanium dioxide le li-stabilizer.
4, litlhahiso tsa tšebeliso
Palo ea tlatsetso: hangata 3% -5% ea boima ba thepa, e fetoloa ho latela litlhoko tsa ho hanyetsa boemo ba leholimo;
Tšireletso ea ts'ebetso: Ho hlokahala polokelo e sa keneleng mongobo, 'me liatlana le likhalase tsa tšireletso li lokela ho aparoa nakong ea ts'ebetso.
Ela Hloko: Ho falla ha titanium dioxide ka tšepe e boima liphaepheng tse amanang le metsi ho lokela ho netefatsoa ka tieo ho netefatsa hore ho latela maemo a bohloeki.
