Titanium dioxide, tseem hu ua titanium dioxide (TiO₂), yog ib hom xim dawb inorganic uas siv dav hauv ntau yam lag luam thiab hu ua "kub dawb ntawm kev lag luam". Nws paub txog nws qhov dawb siab, npog tau zoo, thiab tiv taus huab cua zoo heev, uas tuaj yeem txhim kho qhov zoo nkauj thiab kev ua tau zoo ntawm cov khoom.
cov khoom tseem ceeb
Kev tsis muaj tshuaj lom neeg: Titanium dioxide tsis yaj hauv dej, cov kua qaub tsis muaj zog, thiab dilute inorganic acids ntawm chav tsev kub, tsuas yog yaj hauv cov kua qaub muaj zog xws li hydrofluoric acid lossis concentrated sulfuric acid; Nws cov qauv siv lead ua ruaj khov thiab tsis yooj yim cuam tshuam nrog cov pa roj xws li oxygen thiab carbon dioxide.
Cov khoom tsis raug tswj: Raws li Tuam Tshoj daim ntawv teev npe tswj kev xa khoom tam sim no (xws li Kev Tshaj Tawm No. 51 ntawm Ministry of Commerce hauv xyoo 2024), titanium dioxide tsis tau teev npe ua khoom siv ob zaug, thiab kev xa khoom tsuas yog yuav tsum ua raws li cov kev cai saib xyuas kev lag luam ib txwm muaj.
Titanium dioxide ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam:
Cov txheej thiab yas: Rutile titanium dioxide (xws li Komu R-768) muaj kev npog siab thiab tiv taus huab cua, uas tuaj yeem txhim kho kev tiv taus huab cua ntawm cov kav dej PVC thiab cov yeeb yaj kiab ntim khoom, tiv thaiv kev daj thiab brittleness hauv qab lub teeb, thiab siv dav hauv cov txheej sab nraum zoov thiab cov khoom yas. Nws tuaj yeem ntev lub neej khoom ntau tshaj kaum xyoo thiab tswj kev ruaj khov xim.
Roj hmab, ua ntawv, thiab tshuaj pleev ib ce: Anatase titanium dioxide muab kev dawb thiab kev sib xyaw ua ke hauv kev ua ntawv thiab tshuaj pleev ib ce, thiab feem ntau yog siv los txhim kho kev dawb ntawm ntawv thiab kev zoo nkauj. Ua tus neeg sawv cev rau cov log tsheb roj hmab, hom titanium ua rau muaj kev tiv thaiv kev hnav thiab ncua kev laus.
Qhov ua tau ntau yam ntawm titanium dioxide ua rau nws yog "kev lag luam MSG", uas cuam tshuam txog yuav luag txhua qhov xwm txheej uas xav tau kev ua kom dawb lossis kev txhim kho kev ua tau zoo. Xaiv Bontecn Group Tuam Tshoj titanium dioxide, nrog cov kws tshaj lij kev tshaj lij los tiv thaiv koj cov txheej txheem ntau lawm.
