Aluminium hydroxide cov khoom

Aluminium hydroxide yog lub zog dawb nrog amphotericreaties, reacting nrog ob lub zog muaj zog thiab muaj zog. Aluminium hydroxide yog insoluble hauv dej tab sis soluble hauv cov muaj zog acids thiab muaj zog hauv paus. Nws muaj ntau yam khoom, suav nrog cov hauv qab no:
1. Acidity: Aluminium hydroxide yog cov acidic tsis muaj zog thiab cov pa roj monophotic. Nws reacts nrog cov hauv paus muaj zog los ua cov peev txheej metaaluminates thiab dej. Piv txwv li, txhuas hydroxide reacts nrog sodium hydroxide los ua cov sodium metaaluminate thiab dej.
2. amphoteric: Aluminium hydroxide yog ib qho amphoteric hydroxide uas cuam tshuam nrog ob lub hauv paus muaj zog thiab muaj zog. Nws rov qab nrog cov acids los ua cov ntsev txhuas thiab dej, thiab nrog cov hauv paus kom tsim cov khoom siv metaaluminates thiab dej.
3. Decomposition: Aluminium hydroxide paub txog decomposes thaum cua sov, sib sau aluminium oxide thiab dej. Yog li ntawd, qhov kub thiab sov lub sijhawm yuav tsum ua tib zoo tswj kom tsis txhob decomposition.
4. Adsorption: Aluminium hydroxide muaj Adsorption Proterties, Adsorbing impurities xws li tau ncua cov teeb meem thiab pigments nyob rau hauv kev daws teeb meem. Yog li ntawd, aluminium hydroxide yog siv los ua adsorbent hauv kev npaj kom muaj dej ntws los yog muaj peev xwm hloov ntawm lub teeb los ntawm kev xav txog thiab rov ua dua tshiab. Yog li ntawd, nws feem ntau yog siv los ua cov khoom siv tawm ntawm cov khoom siv kho qhov muag xws li tsom iav, tsom iav, thiab cov ntsiab muag.
6. Corrosion Kuj: Aluminium hydroxide yog corrosion resistant, tiv taus corrosion hauv kev daws teeb meem lossis alkaline. Yog li ntawd, nws feem ntau siv los ua txheej lossis hauv ob sab hauv kev tsim cov khoom ntawm corrosion- cov ntaub ntawv resistant.
7. Nplaim taws retardancy yog nplaim taws retardant, inhibiting kev sib txuas thiab tawg. Yog li ntawd, nws feem ntau siv los ua nplaim taws retardant hauv kev tsim cov khoom siv hluav taws thiab cov khoom tawg.
8. Kev siv tshuaj kho mob: Aluminium hydroxide kuj tseem muaj cov ntawv thov kho mob, siv los kho cov mob xws li hyperacidity thiab pais plab. Nws neutralizes plab acid, relieves mob, thiab txhawb kev tsim dua tshiab thiab kho ntawm lub plab zom mov.
Hauv cov ntsiab lus, Aluminium hydroxide yog ib qho khoom siv tseem ceeb nrog ntau yam khoom thiab cov ntawv thov. Nws cov khoom thiab siv tau zoo sib xws rau nws cov qauv. Nkag siab txog cov khoom siv thiab siv cov txhuas hydroxide yuav pab koj nkag siab zoo dua thiab siv nws.
