Aluminium hydroxide, lub formulation ntawm uas yog Al (OH) 3, yuav muaj nyob rau hauv qhov nyob rau hauv cov nram no cov ntaub ntawv: gibbsite, uas yog ib tug mineral, thiab doyleite, nordstrandite thiab bayerite, tag nrho cov uas tsis tshua muaj polymorphs. Raws li nws cov khoom, peb yuav hais tias txhuas hydroxide zoo li yuav ib tug antacid. Nws muaj ntau yam kev siv, thawj cov uas yog kev kho mob daim ntawv thov.
Tshuaj khoom
Muaj ntau ntau yam ntaub ntawv ntawm txhuas oxide, nrog rau ob crystalline thiab uas tsis yog-crystalline cov ntaub ntawv. Nws yog ib qho hluav taws xob insulator, uas txhais tau tias nws tsis ua hluav taws xob, thiab nws kuj muaj siab kuj thermal conductivity. Nyob rau hauv tas li ntawd, nyob rau hauv nws crystalline daim ntawv no, Corundum, nws hardness ua rau nws haum raws li ib tug abrasive. Lub siab melting point ntawm txhuas oxide ua rau nws ib tug zoo refractory khoom rau meem high-kub yeej siv xws li kilns, rauv taws nte, incinerators, reactors ntawm ntau yam xaiv, thiab crucibles.
Thaj chaw ntawm txhuas hydroxide
Lub lim txhuas hydroxide muaj daim ntawv ntawm loj hmoov ntawm dawb xim los yog granules nrog ceev ze li ntawm 2.42 g ib mL. Aluminium hydroxide yuav tsis yaj nyob rau hauv dej, tab sis yuav yaj xwb nyob rau hauv bases thiab acids. Koj yeej yuav tau txais txhuas hydroxide ua raws li ib tug amphoteric tshuaj nyob rau hauv cov dej. Yog hais tias ib tug muaj zog paus yog tam sim no, txhuas hydroxide yuav ua raws li ib tug acid. Thiab yog hais tias ib tug muaj zog acid yog tam sim no, nws yuav ua raws li ib tug muaj zog paus.
Aluminium hydroxide tsum tau muab daws ceev faj vim hais tias nws raug tus kab mob yuav ua rau voos. Txawm li cas los, tsuas yog me thiab residual kev raug mob yuav tsum tam sim no. Raws li rau flammability, txhuas hydroxide yog tsis flammable thiab yuav tsis hlawv. Dhau li ntawd, txhuas hydroxide yog tsis reactive, yog li ntawd, nws yog ib ruaj khov nyob rau hauv ob qho tib si hluav taws thiab dej tej yam kev mob.
Daim ntaub ntawv ntawm txhuas hydroxide
Aluminium hydroxide muaj kom ntau daim ntaub ntawv; ib co neeg ntseeg hais tias cov kev siv yog tiag tiag txom. Cia li los qhia broadness ntawm kev siv, peb yuav hais tias txhuas hydroxide yog siv raws li mordant nyob rau hauv dyes, purifier rau dej, muaj rau tshuaj pleev ib ce, thiab txawm nyob rau hauv raws li ib tug keeb rau dab nyob rau hauv photography. Tseem muaj ntaub ntawv sau npe ntawm me cim nyob rau hauv ceramics thiab siv. Tab sis qhov tseem ceeb tshaj teb qhov twg txhuas hydroxide yog thov yog tshuaj.
Daim ntaub ntawv nyob rau hauv cov tshuaj
Muab hais tias txhuas hydroxide yog tau neutralize acids, nws ua hauj lwm pab raws li ib tug natural antacid. Aluminium hydroxide kuj muaj ib tug tseem ceeb cuab yeej raws li nws nkoos lub cev ntawm tib neeg. Dhau li ntawd, ntau yam tshuaj tiv thaiv, xws li cov neeg uas yog siv los kho tus kab mob siab B, kab mob siab A, thiab tetanus, yog npaj siv txhuas hydroxide. Nws muaj peev xwm yuav tau siv rau cov kev kho mob ntawm lub raum cov neeg mob uas muaj theem siab ntawm phosphates nyob rau hauv cov ntshav vim lub raum tsis ua hauj lwm. Qhov no pab tau feature tshwm sim vim cov muaj peev xwm ntawm txhuas hydroxide khi nrog phosphates. Tom qab losis tswvyim dabtsi nrog txhuas hydroxide, phosphates yog flushed tawm ntawm tib neeg lub cev yooj yim.
Tshuaj pleev ib ce daim ntawv thov
Muaj ntau ntau yam ntaub ntawv sau npe rau txhuas hydroxide nyob rau hauv lub teb ntawm tshuaj pleev ib ce. Aluminium hydroxide yog feem ntau siv rau zus tau tej cov lipsticks, ua-ups, thiab lwm yam khoom rau ntawm daim tawv nqaij. Nws yog siv muaj vim hais tias nws yog lig ruaj khov thiab tsis lom rau cov neeg. Tej zaum txhuas hydroxide manufacturers ntawm tshuaj pleev ib ce kuj siv tau txhuas hydroxide yuav tsim cleansers rau daim tawv nqaij, suntan khoom, lub cev muab tshuaj pleev, thiab moisturizers. Tej kho mob khoom, piv txwv li, zawv plaub hau, tshuaj txhuam hniav, deodorants thiab ntau lwm tus neeg, kuj koom nrog kev siv ntawm txhuas hydroxide. Aluminium hydroxide tej thaum kuj siv rau kev tiv thaiv ntawm tib neeg daim tawv nqaij.
Daim ntawv thov nyob rau hauv kev lag luam
Qhob yuav tsis tau ua tsis tau txhuas hydroxide. Nyob rau theem ntawm zus tau tej cov pob zeb txhuas hydroxide yog ntxiv rau xis mas. Nws tseem yog heev pab tau vim MAAs nrog txhuas hydroxide tas li ntawd dries sai yog hais tias nws yog raug los ua cua sov. Ceramics thiab khob ob industrial thiab tsev daim ntawv thov yog manufactured siv txhuas hydroxide. Qhov tseem pab tau feature ntawm txhuas hydroxide thaum nws yog ntxiv rau iav muaj nyob rau hauv lub fact tias nws ua rau iav thaum tshav kub kub-resistant. Nws yog ua tau vim hais tias, raws li muaj lawm twb hais, txhuas hydroxide yog tsis flammable thiab muaj siab melting point. Aluminium hydroxide ua ke nrog polymers zoo li yuav ib tug zoo heev hluav taws retardant.
