Kugwiritsa Ntchito Titanium Dioxide mu Makampani Opanga Mapulasitiki

Kugwiritsa ntchito titanium dioxide (TiO ₂) mumakampani opanga pulasitiki kumaonekera kwambiri m'mbali izi: monga utoto wapakati, ukhoza kusintha kwambiri kuyera ndi mphamvu yophimba zinthu za pulasitiki, kukwaniritsa kuwala kwakukulu kudzera mu kufalikira ndi kuyamwa kwa kuwala, makamaka mu ma resini owoneka achikasu, tinthu tating'onoting'ono ta titanium dioxide tokhala ndi mainchesi a 0.15-0.3 μ m tingapangitse gawo labuluu kumbuyo kuti liwonjezere mphamvu yophimba; Nthawi yomweyo, titanium dioxide imachedwetsa kukalamba kwa pulasitiki bwino ndikuwonjezera kukana kwa nyengo mwa kuyamwa kuwala kwa ultraviolet. Zinthu zakunja ziyenera kugwiritsa ntchito mtundu wa rutile ndikuwonjezeredwa ndi ukadaulo wochizira pamwamba monga silicon, aluminiyamu, ndi zirconium kuti apewe mavuto a pore omwe amayamba chifukwa cha kuphulika kwa madzi panthawi yokonza kutentha kwambiri; Ponena za kukhazikika kwa kutentha, titanium dioxide imatha kusintha magwiridwe antchito a pulasitiki m'malo otentha kwambiri pochepetsa zochita za photochemical kudzera munjira zosinthira pamwamba (monga zokutira zopanda organic), kuonetsetsa kuti mphamvu zamakanika ndi kulimba kwa utoto wa zinthu pansi pa mikhalidwe yovuta. Njira zogwiritsira ntchito titanium dioxide zimasiyana pamitundu yosiyanasiyana ya mapulasitiki - ma polyolefin amafunika kusamala kuti asatayike komanso kuti asasinthe mtundu, zinthu zolimba za PVC zimadalira mphamvu ya titanium dioxide yoletsa ufa, pomwe ABS imayang'ana kwambiri pakuwongolera mawonekedwe ndi mawonekedwe a makina. Mu ntchito zachizolowezi, kuchuluka kwa titanium dioxide yomwe imawonjezeredwa nthawi zambiri kumayendetsedwa pa 3% ~ 5% kuti igwirizane bwino ndi magwiridwe antchito, ndipo kuchuluka kwa utoto wapadera kumatha kufika 40% ~ 70%; Mwa kukonza kufalikira kwa tinthu tating'onoting'ono (monga 2-35 μ m) ndi njira zochizira pamwamba, Bontecn Group China titanium dioxide yapeza kuyera kwambiri, kukana nyengo, komanso kukhazikika kwa kukonza m'minda monga mafilimu apulasitiki, ma profiles a zitseko ndi mawindo, ndi zida zamagalimoto.
