Dab tsi yogAntimony Trioxidesiv rau?
Antimony Trioxidefeem ntau yog siv ua ke nrog lwm cov tebchaw los muab cov nplaim hluav taws kub.Daim ntawv thov tseem ceeb yog cov nplaim hluav taws xob sib xyaw ua ke nrog cov khoom siv halogenated.Kev sib xyaw ua ke ntawm cov halides thiab antimony yog qhov tseem ceeb rau cov nplaim hluav taws kub nyhiab rau cov polymers, pab tsim cov nplaim hluav taws tsawg.Cov nplaim hluav taws zoo li no muaj nyob hauv cov khoom siv hluav taws xob, textiles, tawv, thiab coatings.Antimony (III) Oxidekuj yog ib tug opacifying tus neeg saib xyuas rau tsom iav, ceramics thiab enamels.Nws yog ib qho tseem ceeb catalyst nyob rau hauv zus tau tej cov polyethylene terephthalate (PET yas) thiab vulcanization ntawm roj hmab.
