Aluminium hydroxidemuaj qhov dawb zoo, qhov ntsuas refractive nruab nrab, yooj yim rau kev ua tiav, nrog rau kev tiv thaiv hluav taws zoo, kev tswj hwm pa luam yeeb thiab lwm yam ntxwv, yog li ntawd txhuas hydroxide ua pob zeb dag yog cov khoom siv zoo heev.
Cov khoom siv pob zeb dag ua los ntawm cov khoom siv raw aluminium hydroxide muaj cov yam ntxwv hauv qab no:
Lub cev nyhav sib dua, tus nqi qis, yooj yim ua, xim zoo, tawv zoo, tuaj yeem ua tiav seamless stitching, 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 thiab hu ua cov khoom siv hauv tsev siv dav.
Tam sim no, lub ntiaj teb cov pob zeb dag nrog txhuas hydroxide txhua xyoo xav tau txog li 700,000 tons, thiab txhua xyoo nrog txog li 10 feem pua ntawm tus nqi ntawm kev nce. Ntau cov ntaub ntawv tsis tiav, Tuam Tshoj cov pob zeb dag kev lag luam txhua xyoo xav tau hauv 1100 square meters saum toj no, thiab tam sim no cov tuam txhab tsim pob zeb dag hauv tsev 'peev xwm tsim khoom tsuas yog 7 lab square meters, kev ua lag luam loj heev.
Vim yog cov txheej txheem sintering tshwj xeeb thiab cov txheej txheem desilication tob ntawm sodium chlorate kua, cov khoom alumina tsim los ntawm alkali lime sintering txheej txheem muaj cov yam ntxwv ntawm cov dawb siab thiab cov ntsiab lus hlau tsawg. Raws li kev txhim kho sai ntawm kev lag luam pob zeb dag, cov kab tsim khoom txhuas hydroxide tau nthuav dav sai rau kev lag luam hauv tsev thiab txawv teb chaws.
Cov hauv qab no yog cov chaw tsim khoom ntawm cov pob zeb dag nrog cov txhuas hydroxide peb txoj kev tsim khoom raws li hauv qab no:
(1) cov khoom tsim los ntawm txoj kev sib cais carbon muaj qhov dawb me ntsis siab dua, tus nqi pH siab dua thiab SiO2% ntawm cov khoom, thiab qhov huv qis dua. Kev tsim cov khoom sib cais carbon, qhov loj me ntawm cov khoom qub yog me me, qhov chaw ntawm cov noob yog ntxhib heev, cov siv lead ua siv lead ua xoob, qib crystallization tsis zoo, qhov hws loj, qhov no yog qhov laj thawj rau qhov nqus roj ntau ntawm cov khoom, nrog nws cov khoom tsim cov pob zeb dag dawb.
(2) qhov dawb ntawm cov khoom tsim los ntawm txoj kev faib hom yog qis dua me ntsis, tus nqi nqus roj tsawg, tus nqi pH thiab SiO2% ntawm cov khoom yog qis dua, thiab qhov huv ntawm cov khoom yog siab dua. Kev tsim cov khoom, kev loj hlob ntawm cov siv lead ua tiav dua, qhov chaw ntawm cov noob siv lead ua huv dua, cov siv lead ua siv lead ua ntom ntom, qib ntawm crystallization zoo dua, qhov sib txawv ntawm cov khoom me me, qhov no yog cov khoom siv roj nqus qis, nrog nws cov khoom tsim cov phaj pob zeb dag muaj zog siab.
(3) cov khoom tsim los ntawm txoj kev sib tov muaj qhov nqus roj qis tshaj plaws nrog rau qhov dawb hauv qab. 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.
