Zincoxide CAS: 1314-13-2

Zinc oxide (ZnO) yog ib qho tshuaj sib xyaw ua ke uas muaj ntau yam kev siv thoob plaws ntau yam lag luam. Hauv kev lag luam pleev kom zoo nkauj, nws yog ib qho tseem ceeb hauv cov tshuaj pleev thaiv hnub, muab kev tiv thaiv zoo tiv thaiv cov teeb meem ultraviolet (UV). Nws lub peev xwm los cuam tshuam thiab tawg cov teeb UV ua rau nws yog ib qho tseem ceeb rau kev tsim cov khoom siv tawv nqaij thiab cov khoom siv tiv thaiv hnub. Hauv kev lag luam tshuaj, zinc oxide siv rau hauv ntau yam khoom siv kho mob, suav nrog cov tshuaj pleev, tshuaj pleev, thiab tshuaj tua kab mob. Nws muaj cov yam ntxwv so thiab tiv thaiv, ua rau nws muaj txiaj ntsig zoo rau kev kho cov mob ntawm daim tawv nqaij xws li kub hnyiab, khaus, thiab pob khaus. Zinc oxide daim ntawv thov nthuav dav mus rau kev lag luam roj hmab, qhov twg nws ua haujlwm ua ib qho khoom ntxiv tseem ceeb hauv kev tsim cov khoom siv roj hmab. Nws txhim kho cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm cov tshuaj sib xyaw roj hmab, pab txhawb kev ua haujlwm ntev thiab kev ua tau zoo ntawm cov khoom siv roj hmab xws li log tsheb, khau, thiab siv txoj siv. Ntxiv mus, ZnO pom kev siv dav hauv kev lag luam ceramic. Nws ua haujlwm ua cov kua dej hauv cov iav ceramic, pab hauv kev yaj thiab kev sib txuas ntawm cov khoom siv ceramic thaum lub sijhawm hlawv. Tsis tas li ntawd xwb, nws ua haujlwm ua cov xim thiab ua kom pom tseeb, muab cov xim thiab qhov tsis pom tseeb rau cov khoom siv ceramic xws li cov vuas, cov tais diav, thiab cov khoom siv hauv chav dej. Hauv kev ua liaj ua teb, zinc oxide siv ua cov chiv micronutrient los daws qhov tsis txaus zinc hauv av, txhawb kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag. Nws lub luag haujlwm hauv kev muab zinc tseem ceeb rau cov qoob loo pab txhawb kev ua liaj ua teb ntau ntxiv thiab cov khoom zoo. Ntxiv mus, zinc oxide siv rau hauv kev tsim cov varistors rau kev siv hluav taws xob, ua tus catalyst hauv cov txheej txheem tshuaj lom neeg, thiab ua ib feem hauv kev tsim cov xim, txheej, thiab cov xim. Nws cov kev siv ntau yam qhia txog qhov tseem ceeb ntawm zinc oxide ua cov khoom siv tseem ceeb nrog kev koom tes dav dav rau ntau yam kev lag luam.
