Emkhakheni wamapulasitiki, ukusetshenziswa kwezithasiselo nama-filler kubalulekile ukuthuthukisa izakhiwo nokusebenza komkhiqizo wokugcina. I-Titanium dioxide iyisengezo esithola ukunakwa okukhulu. Uma yengezwe kui-polypropylene masterbatch, i-titanium dioxide inganikeza uhla lwezinzuzo, kusukela ekuthuthukisweni kokumelana ne-UV kuya ekukhangekeni okuthuthukisiwe kobuhle.
I-Titanium dioxide iyi-titanium oxide eyenzeka ngokwemvelo eyaziwa ngekhono layo lokudlulisela ubumhlophe, ukukhanya, nokufiphala kwezinto ezihlukahlukene. Kuamapulasitiki, ngokuvamile isetshenziswa njenge-pigment ukuze kuzuzwe imibala egqamile futhi inikeze isivikelo emiphumeleni eyingozi yemisebe ye-UV. Ku-polypropylene masterbatch, ukungezwa kwe-titanium dioxide kungaba nomthelela omkhulu kukhwalithi iyonke yomkhiqizo wokugcina.
Enye yezinzuzo eziyinhloko zokwengeza i-titanium dioxide ku-polypropylene masterbatch amandla ayo okuthuthukisa ukumelana ne-UV. I-Polypropylene iyi-polymer ethandwayo ye-thermoplastic eyaziwa ngokuhlukahluka kwayo futhi isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ukusuka emaphaketheni kuya ezingxenyeni zezimoto. Kodwa-ke, ukuchayeka isikhathi eside elangeni kungabangela ukuba impahla yonakale, kubangele ukushintsha kombala kanye nokuncipha kwezakhiwo zemishini. Ngokufaka i-titanium dioxide ku-masterbatch, umkhiqizo we-polypropylene owumphumela ungamelana kangcono nemiphumela elimazayo yemisebe ye-UV, wandise ukuphila kwawo futhi ugcine ukukhanga kwawo okubonakalayo.
Ngaphezu kwalokho, ukungezwa kwetitanium dioxideingathuthukisa kakhulu izakhiwo zobuhle ze-polypropylene masterbatch. I-pigment isebenza njenge-ejenti emhlophe, ikhulisa ubumhlophe nokufiphala kwezinto. Lokhu kunenzuzo ikakhulukazi ezinhlelweni zokusebenza lapho kudingeka ukubukeka okuhlanzekile, okufanayo, njengokukhiqizwa kwezimpahla ezithengwayo, impahla yasendlini kanye nemishini yezokwelapha. Ukukhanga okuthuthukisiwe okubonakalayo ngokusetshenziswa kwe-titanium dioxide kungakhuphula inani elibonakalayo lemikhiqizo yokugcina, kuyenze ikhange nakakhulu kubathengi nabasebenzisi bokugcina.
Ngaphezu kwezinzuzo ezibonakalayo nezivikelayo, i-titanium dioxide ingathuthukisa ukusebenza okuphelele kwama-polypropylene masterbatches. Ngokuhlakaza ngempumelelo nokubonisa ukukhanya, ama-pigments angasiza ekunciphiseni ukwakheka kokushisa ngaphakathi kwento, ngaleyo ndlela kusize ukuthuthukisa ukuzinza kokushisa. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho ukumelana nezinga lokushisa kuyisici esibalulekile, njengokwenziwa kwezingxenye zezimoto kanye nemishini kagesi.
Kubalulekile ukuqaphela ukuthi ukufakwa ngempumelelo kwe-titanium dioxide ku-polypropylene masterbatch kuncike ekusetshenzisweni kokwakheka kwe-masterbatch yekhwalithi ephezulu. Ukusatshalaliswa kwezingulube ku-polypropylene matrix kubalulekile ukuze kuqinisekiswe umbala ofanayo nokusebenza kahle. Ngakho-ke, abakhiqizi kufanele bakhethe ngokucophelela umphakeli we-masterbatch onobuchwepheshe nobuchwepheshe ukuze bathole ukuhlakazeka okungaguquki nokuthembekile kwe-titanium dioxide.
Kafushane, ukwengeza i-titanium dioxide ku-polypropylene masterbatch kunikeza izinzuzo eziningi, kusukela ekuthuthukisweni kokumelana ne-UV kuya ekuthuthukisweni kobuhle nokusebenza. Njengoba isidingo semikhiqizo yepulasitiki esezingeni eliphezulu, emihle futhi ehlala isikhathi eside siqhubeka sikhula, indima ye-titanium dioxide kuma-polypropylene masterbatches izobaluleka kakhulu. Ngokusebenzisa amandla alesi sombala esishintshashintshashintshayo, abakhiqizi bangathuthukisa ikhwalithi nokuthengiseka kwemikhiqizo yabo ye-polypropylene ukuze bahlangabezane nezidingo ezishintshayo zezimboni nabathengi abahlukahlukene.
