Kodi titanium dioxide imagwiritsidwa ntchito bwanji?

Titanium dioxide, yomwe imadziwikanso kuti titanium dioxide (TiO2₂), ndi utoto woyera wosapangidwa bwino womwe umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo umadziwika kuti "golide woyera wa mafakitale". Umadziwika chifukwa cha kuyera kwake kwakukulu, kuphimba kwake mwamphamvu, komanso kukana kwabwino kwa nyengo, zomwe zingathandize kwambiri mawonekedwe ndi magwiridwe antchito a zinthu.

Kusagwira ntchito kwa mankhwala: Titanium dioxide siisungunuka m'madzi, imakhala ndi ma asidi ofooka, ndipo imachepetsa ma asidi osapangidwa m'thupi kutentha kwa chipinda, imasungunuka m'ma asidi amphamvu monga hydrofluoric acid kapena concentrated sulfuric acid; Kapangidwe kake ka kristalo ndi kokhazikika ndipo sikungagwirizane mosavuta ndi mpweya monga mpweya ndi carbon dioxide.
Zinthu Zosalamulirika: Malinga ndi mndandanda wamakono wazinthu zotumizira kunja ku China (monga Chidziwitso Nambala 51 cha Unduna wa Zamalonda mu 2024), titanium dioxide siili m'gulu la zinthu zogwiritsidwa ntchito kawiri, ndipo zinthu zotumizidwa kunja zimangofunika kutsatira zofunikira zachikhalidwe zoyang'anira malonda.
Titanium dioxide imagwira ntchito yofunika kwambiri m'mafakitale ambiri:
Zophimba ndi pulasitiki: Rutile titanium dioxide (monga Komu R-768) imaphimba kwambiri komanso imateteza nyengo, zomwe zingathandize kuti mapaipi a PVC ndi mafilimu opakidwa azilimbana ndi nyengo, kupewa chikasu ndi kusweka pamene kuwala kukuwala, ndipo imagwiritsidwa ntchito kwambiri mu zophimba zakunja ndi zinthu zapulasitiki. Imatha kukulitsa moyo wa chinthucho ndi zaka zoposa khumi ndikusunga mtundu wokhazikika.
Rabala, kupanga mapepala, ndi zodzoladzola: Anatase titanium dioxide imapereka kuyera kofanana komanso kufalikira popanga mapepala ndi zodzoladzola, ndipo imagwiritsidwa ntchito kwambiri pokonza kuyera kwa mapepala ndi kapangidwe ka zodzoladzola. Monga chothandizira cholimbitsa matayala a rabala, mtundu wa titanium umathandizira kukana kuwonongeka ndikuchedwetsa kukalamba.
Kugwira ntchito kwa titanium dioxide m'njira zambiri kumapangitsa kuti ikhale "MSG ya mafakitale", yomwe ikuphatikizapo zochitika zonse zomwe zimafuna kuyera kapena kukulitsa magwiridwe antchito. Sankhani Bontecn Group China titanium dioxide, yokhala ndi akatswiri aukadaulo kuti ateteze njira yanu yopangira.
