Kev lag luam txhuas hydroxide hu ua alumina hydrate, vim nws qhov dawb zoo, qhov sib piv refractive nruab nrab, yooj yim rau kev ua tiav, nrog rau nplaim taws zoo, kev ua pa luam yeeb, yog li ntawd txhuas hydroxide ua cov khoom siv pob zeb zoo heev.
Cov khoom siv pob zeb ua los ntawm txhuas hydroxide muaj cov yam ntxwv hauv qab no:
Lub teeb yuag, tus nqi qis, yooj yim rau kev ua tiav, xim zoo, zoo toughness, seamless splicing tuaj yeem ua tiav, thiab nws txoj kev tsim khoom yooj yim, lub voj voog luv luv. Yog li ntawd, nws sai sai kis mus rau txhua qhov chaw ntawm lub ntiaj teb, hu ua ib hom khoom siv dav dav hauv tsev.
Tam sim no, lub ntiaj teb txhua xyoo xav tau txhuas hydroxide rau pob zeb dag yog li 700,000 tons, thiab tus nqi loj hlob txhua xyoo yog li 10%. Ntau cov ntaub ntawv tsis tiav, Tuam Tshoj txhua xyoo xav tau kev lag luam pob zeb dag hauv 1100 square meters, thiab tam sim no lub peev xwm tsim khoom hauv tsev ntawm cov chaw tsim khoom pob zeb dag tsuas yog 7 lab square meters, lub peev xwm ua lag luam yog loj heev.
Vim yog cov txheej txheem sintering tshwj xeeb thiab cov txheej txheem desilication tob ntawm sodium chlorate kua hauv kev tsim cov alumina los ntawm cov txheej txheem caustic lime sintering, cov khoom lag luam aluminium hydroxide tsim tawm muaj cov yam ntxwv ntawm cov dawb siab thiab cov ntsiab lus hlau tsawg, thiab muaj cov txiaj ntsig tshwj xeeb. Raws li kev txhim kho sai ntawm kev lag luam pob zeb dag, cov kab ntau lawm ntawm cov khoom siv aluminium hydroxide filler tau nthuav dav sai sai kom nthuav dav kev lag luam hauv tsev thiab txawv teb chaws.
Cov hauv qab no yog cov chaw tsim khoom ntawm txhuas hydroxide rau cov pob zeb dag nrog rau kev tsim cov txhuas hydroxide peb cov txheej txheem tau qhia raws li hauv qab no:
(1) cov khoom tsim los ntawm kev sib cais carbon muaj qhov dawb me ntsis siab dua, pH siab dua thiab SiO2% siab dua, thiab qhov huv qis dua. Txoj kev tsim cov khoom siv carbon, qhov loj me ntawm cov khoom yog me me, qhov chaw ntawm cov noob yog ntxhib heev, cov siv lead ua siv lead ua yog xoob dua, qib ntawm crystallization tsis zoo, qhov porosity loj dua, qhov no yog cov khoom roj nqus tus nqi siab dua, nrog nws cov khoom tsim cov pob zeb dag dawb yog siab.
(2) cov khoom tsim los ntawm txoj kev faib tawm muaj qhov dawb qis dua, qhov nqus roj tsawg dua, pH qis dua, SiO2% qis dua ntawm cov khoom thiab qhov huv dua. Cov khoom tsim los ntawm txoj kev faib noob, kev txhim kho siv lead ua kom zoo dua, qhov chaw ntawm cov khoom siv lead ua kom ci dua thiab huv dua, siv lead ua kom ntom dua, qib siv lead ua zoo dua, qhov sib txawv ntawm cov khoom me me, qhov no yog qhov nqus roj tsawg ntawm cov khoom koj xav tau, nrog nws cov khoom tsim cov pob zeb dag.
(3) cov khoom tsim los ntawm txoj kev sib tov muaj qhov nqus roj qis tshaj plaws thiab qhov dawb qis tshaj plaws. Txoj kev sib xyaw ntawm cov khoom, ob qho tib si cov khoom loj ntawm cov khoom siv raw, thiab cov khoom me me ntawm cov pa roj carbon filler, gradation, sau tag nrho, ua rau cov khoom txhuas hydroxide ntawm cov roj nqus tus nqi txo qis heev, tib lub sijhawm, qhov viscosity ntawm cov khoom qis, tsawg dua 20000 eps, nrog nws tus nqi qis, kev tsim cov pob zeb dag thiab cov neeg siv khoom tsis tas yuav faib cov txhuas hydroxide filler, txuag Labour.
