Aluminium hydroxide ntsug sib tsoo zeb

Aluminium hydroxide yog ib yam khoom siv tshuaj lom neeg uas siv dav dav, nws ruaj khov zoo, tsis muaj tshuaj lom, tsis muaj saj, thiab tau dhau los ua ib qho khoom tseem ceeb hauv kev siv hluav taws xob, khoom siv hluav taws xob, kev ua ntawv, tshuaj thiab lwm yam lag luam. Nrog rau kev ua kom zoo dua ntawm aluminium hydroxide, cov qauv hluav taws xob ntawm qhov chaw thiab cov qauv siv lead ua hloov pauv, ua rau muaj qhov cuam tshuam ntawm qhov chaw thiab qhov loj me, yog li nws muaj cov yam ntxwv tshwj xeeb hauv kev ua haujlwm tshuaj lom neeg, kev ua haujlwm hluav taws xob, cov yam ntxwv ntawm qhov chaw thiab lwm yam, thiab muaj ntau yam haujlwm tshwj xeeb. Cov hmoov txhuas hydroxide uas tsim los ntawm aluminium hydroxide ntsug zeb tsis yog tsuas yog cov khoom siv ua haujlwm xwb, tab sis kuj muab kev cia siab dav dav rau kev tsim cov khoom siv tshiab, thiab ua lub luag haujlwm tseem ceeb heev hauv ntau qhov chaw ntawm kev lag luam hauv tebchaws.Guilin Hongchengraws li cov chaw tsim khoom ntawm aluminium hydroxide ntsug zeb, hnub no rau koj los qhia txog kev lag luam tseem ceeb ntawm aluminium hydroxide.

Kev lag luam daim ntawv thov tseem ceeb ntawm txhuas hydroxide:

1. Kev lag luam tiv thaiv kev sib xyaw ua ke: txhuas hydroxide muaj qhov nyuaj nruab nrab, ruaj khov lub cev thiab tshuaj lom neeg ntawm chav tsev kub, tsis muaj tshuaj lom, thiab tus nqi tsim khoom qis. Aluminium hydroxide rhaub rau txog 220C pib nqus cua sov decomposition, tso cov dej sib xyaw ua ke. Vim tias cov txheej txheem endothermic dehydration no qeeb qhov kev sib xyaw ntawm cov polymer thiab qeeb qeeb qhov kev sib xyaw ua ke. Nws yog raws li kev sib xyaw ua ke ntawm kev nqus cua sov ntau, thiab tsuas yog tso cov dej pa hauv qhov kev sib xyaw ua ke ntawm cua sov, thiab yuav tsis tsim cov pa lom, flammable lossis corrosive, txhuas hydroxide tau dhau los ua cov khoom tseem ceeb inorganic flame retardant filler.

2. Cov khoom sau thiab ntxiv rau cov nplaum thiab cov sealant: Cov khoom sau txhuas hydroxide tuaj yeem txhim kho kev ua haujlwm, lub zog, kev ua kom sov thiab kev nthuav dav thermal ntawm cov nplaum thiab sealant, thiab tuaj yeem txo cov nplaum thiab txo cov nqi khoom. Kev siv cov binder hauv Tebchaws Europe thiab Tebchaws Meskas tab tom loj hlob li 5% hauv ib xyoos, thiab qhov xav tau rau cov sealant tab tom loj hlob 1% hauv Tebchaws Europe.

3. Kev ntim ntawv: txhuas hydroxide hauv kev lag luam ntawv, feem ntau yog siv los ua txheej saum npoo, sau thiab tsim cov ntawv tsis-flammable. Thaum ntxov li xyoo 1940 thiab 1950, txhuas hydroxide pib tsim thiab siv ua cov xim txheej, thiab tau tsim kom muaj qhov ruaj khov ntau lawm, feem ntau yog siv rau kev tsim cov ntawv coated thiab cardboard, carbon carbon ntawv. Hauv Suav teb, daim ntawv thov ntawm txhuas hydroxide hauv kev lag luam ntawv tsawg dua, nrog rau kev txhim kho thiab tsim cov ultrafine txhuas hydroxide, daim ntawv thov ntawm txhuas hydroxide hauv kev lag luam ntawv yuav txuas ntxiv mus ntxiv. Aluminium hydroxide, ua ib hom tshiab ntawm cov xim txheej, piv nrog cov xim ib txwm muaj, nws tus kheej muaj ntau qhov zoo: dawb siab, qhov loj me me, cov duab zoo siv lead ua, kev ua tau zoo sib xws nrog tus neeg sawv cev dawb, kev nqus kua mem zoo. Siv nws ua cov xim, tuaj yeem txhim kho qhov dawb, opacity, smoothness, nqus kua mem ntawm cov ntawv coated, tuaj yeem siv rau hauv kev tsim cov ntawv pleev xim, ntawv thaij duab thiab ntawv txhais lus siab heev thiab lwm yam ntawv siab heev.

4. Tus neeg sawv cev txhuam hniav: txhuas hydroxide tsis muaj tshuaj lom thiab tsis muaj saj, Mohs hardness 2.5-3.5, mos thiab tawv nruab nrab, yog tus neeg sawv cev txhuam tsis muaj zog zoo, txhuas hydroxide hloov cov khoom xyaw ib txwm muaj xws li chalk thiab dicalcium phosphate tuaj yeem ua rau cov tshuaj txhuam hniav nrog kev ua tau zoo. Lub zog tshuaj lom neeg ntawm txhuas hydroxide ua rau nws sib xws nrog lwm cov khoom xyaw hauv cov tshuaj txhuam hniav; lub sijhawm no, nws yog siv dav hauv cov tshuaj txhuam hniav thiab lwm yam tshuaj txhuam hniav zoo.

5. Tshuaj thiab lwm yam: Aluminium hydroxide yog ib qho ntawm cov khoom tseem ceeb ntawm kev kho mob plab. Aluminium gel yog ib qho tshuaj ib txwm muaj rau kev tshem tawm cov kua qaub hauv plab thiab kho cov teeb meem hauv plab. Aluminium chloride npaj los ntawm aluminium hydroxide ua cov khoom siv raw tuaj yeem siv ua cov khoom siv condensant hauv tshuaj thiab tshuaj pleev ib ce. Tsis tas li ntawd, aluminium hydroxide thiab nws cov khoom siv tshwj xeeb ci aluminium oxide tau siv dav hauv cov tshuaj lom neeg, catalysts, plastics, coatings, ceramics, refractory materials, insulation materials, abrasives thiab lwm yam teb.
