Qhov xwm txheej ntawm sodium bicarbonate kev lag luam saw
(1) Txheej txheem cej luam ntawm kev ua cov saw ntawm sodium bicarbonate kev lag luam;
Kev ntws tawm ntawm trona ntau lawm yog trona ore, qhov dej ntws ntawm ammonia ntau lawm yog ntsev nyoos thiab limestone, thiab qhov dej ntws ntawm alkali ntau lawm yog ntsev nyoos thiab ammonia hluavtaws. Cov roj siv hluav taws xob tseem ceeb yog cov thee siv roj, thiab qee lub tuam txhab siv roj cua.
Cov khoom tseem ceeb ntawm sodium bicarbonate tshauv kev lag luam yog lub teeb alkali thiab hnyav alkali, thiab hnyav alkali yog hloov pauv los ntawm lub teeb alkali. Nws yog kev siv roj ntsha ntawm kev ua tiav nitrogen chiv thiab kuj tseem siv tau rau kev tsim cov roj teeb, ua hluav taws xob, thiab zas xim.
Lub teeb alkali feem ntau yog siv hauv kev lag luam tshuaj txhua hnub, tshuaj ntxuav thiab khoom noj khoom haus. Hnyav alkali feem ntau yog siv los tsim tsev iav. Inorganic ntsev siv lub teeb alkali thiab hnyav alkali raws li kev lag luam sib txawv. Qee qhov kev lag luam hauv nqes qis hauv cov tshuaj ntxuav thiab alumina kev lag luam tuaj yeem hloov qhov cub ntawm cov nqi ntawm sodium bicarbonate tshauv thiab caustic sodium bicarbonate, yog li txo cov nqi tsim khoom.
(2) Txheej txheem cej luam ntawm kev lag luam ntws los ntawm sodium bicarbonate tshauv:
Vim tias cov txheej txheem sib txawv ntau lawm, cov khoom siv raw los siv los ua cov sodium bicarbonate ntoo tshauv kuj tseem sib txawv. Lub ntsiab raw khoom ua los ntawm ammonia-alkali txoj kev yog cov ntsev nyoos thiab limestone, cov khoom tseem ceeb ntawm cov txheej txheem sib xyaw-alkali txheej txheem yog cov ntsev nyoos thiab hluavtaws ammonia, thiab cov khoom tseem ceeb ntawm cov qauv trona yog trona ore. Lub roj tseem ceeb ntawm peb cov txheej txheem alkaline yog thermal thee. Yog li ntawd, cov dej ntws los ntawm sodium bicarbonate cov hmoov tshauv yog ntsev nyoos, limestone, hluavtaws ammonia thiab thermal thee.
1. Kev lag luam ntsev ua kom huv si
Cov ntsev nyoos, tseem hu ua ntsev kev lag luam, yog qhov ntawm ntsev thiab tshuaj kev lag luam. Nws yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj hydrochloric acid, caustic sodium bicarbonate, sodium bicarbonate tshauv, chlorine roj, thiab ammonium chloride. Raws li hom saltfield ntau lawm, Tuam Tshoj' s kev lag luam ntsev tau faib ua zoo ntsev, hiav txwv ntsev thiab pas dej ntsev. Xyoo 2018, peb tsim tau 90,65 lab tons, 58.5% ntsev zoo, 29.5% ntawm hiav txwv ntsev thiab 12.0% ntawm pas dej ntsev. Kev noj cov ntsev nyoos hauv sodium bicarbonate tshauv thiab caustic sodium bicarbonate kev lag luam muaj rau ntau dua 90% ntawm tag nrho cov txiaj ntsig.
