Decomposition Temperature ntawm Aluminium Hydroxide

Cov tshuaj lom neeg ruaj khov ntawm aluminium hydroxide tsis zoo heev, thiab nws muaj zog heev, yog li nws tuaj yeem cuam tshuam nrog cov kua qaub thiab alkalis, thiab nws tuaj yeem decompose ntawm qhov kub thiab txias. Cia peb tham txog qhov decomposition kub ntawm aluminium hydroxide.

1. Aluminium hydroxide tuaj yeem decomposed los ua alumina, thiab calcined ntawm qhov kub ntawm 950-1200 degree kom tau -type alumina hmoov, uas tuaj yeem siv los ua corundum dag; nws tuaj yeem ua rau lub cev qhuav dej ntawm qhov kub qis ntawm 140-150 degree . - hom alumina tau txais.

2. Txij li nws yog cov khoom siv tsis sib haum, tsis muaj qhov xav tau siab rau cov av noo, qhov kub yuav tsum qis dua qhov ntsuas kub ib txwm muaj thiab tiv thaiv lub teeb kom tsis txhob kub siab los ntawm kev raug lub teeb thiab ua rau nws decompose.

3. Aluminium hydroxide yog ib qho muab tub lim nrog lub peev xwm loj ntawm cov cua sov, thiab nws cov cua kub cia thiab thermal conductivity ua rau cov khoom tsis ncav cuag qhov kub thiab txias los yog nqus cov cua sov los ntawm thermal decomposition ntawm cov nplaim hluav taws, yog li ua kom qeeb lossis txo qhov kub nce; Txawm li cas los xij, tsis kho nanohydrogen Lub agglomeration ntawm alumina yog qhov hnyav, ua rau tsis sib xws thermal decomposition tus nqi. Tom qab kev kho cua sov, lub dispersibility ntawm cov hais yog zoo heev, thiab ib tug monomolecular txheej yuav tsim nyob rau hauv lub qhov chaw ntawm lub muab tub lim, uas yuav txo tau nws lub zog nto thiab tsis muaj zog adsorption ntawm hais.
