Yuav ua li cas Calcium Chloride Manufacturers tsim Calcium Chloride

Yuav ua li cas calcium chloride manufacturers tsim calcium chloride

Muaj coob tus crystalline calcium chloride khoom nyob rau hauv kev ua lag luam yog flakes, uas yog, flaky calcium chloride.

Raws li inorganic ntsev, calcium chloride muab faib ua hmoov, flake thiab granular calcium chloride. Calcium chloride yog dav siv nyob rau hauv antifreeze, hluav taws kub tiv thaiv, textile, ua liaj ua teb chiv thiab lwm yam lag luam. Cov txheej txheem tsim tawm ntawm flaky calcium chloride yog muab hydrochloric acid (31 feem pua) thiab limestone hmoov rau hauv cov tshuaj tiv thaiv tank hauv qhov kev faib ua feem ntawm 2,333,601, do thiab hnov ​​​​mob los tsim cov kua qaub calcium chloride, thiab tom qab ntawd txav mus rau hauv cov kua txiv qaub rau kev hloov kho. pH ntawm kev daws. Rau 8.9 ~ 9, ferric hydroxide thiab magnesium hydroxide yog precipitated dua. Tom qab ua kom pom tseeb thiab pom, cov lim tau hloov mus rau lub tais evaporating, rhuab mus rau 172-174 degree kom evaporate, crystallized, sib cais, qhuav thiab dehydrated ntawm 200-240 degree kom tau calcium chloride dihydrate.

Cov txheej txheem kev ua haujlwm tshwj xeeb yog raws li hauv qab no: 1. Soda ash khib nyiab kua rov qab txoj kev: Soda ash khib nyiab kua rov qab txoj kev siv ammonia dej thiab distillation pov tseg cov kua hauv cov dej qab zib ntau lawm ua raw khoom, tab sis nws yuav tsum tau purified, meej, evaporated thiab lwm cov txheej txheem ua ntej siv. Ua pelleted thiab centrifuged. Cov niam cawv sib cais los ntawm sodium chloride yog sib cais, xa mus rau lub evaporator mus txuas ntxiv evaporate thiab mloog zoo, kom cov calcium chloride cov ntsiab lus nce mus txog 70 feem pua, thiab ces ncuav rau hauv lub ntim ntim rau condensation kom tau flaky calcium chloride.

Txoj kev no yog siv nyob rau hauv industrial ntau lawm. Hydrochloric acid limestone hmoov txoj kev: Txoj kev hydrochloric acid limestone hmoov yog siv los ntxiv hydrochloric acid thiab limestone hmoov rau hauv lub reactor ntawm ib tug ratio ntawm 2.2: 1, do kom ua ib tug acid calcium chloride tov, thiab xa mus rau lub clarification tank nyob rau hauv stirring. , thiab ces ntxiv txiv qaub kua txiv los kho cov tshuaj. Lub pH nyob nruab nrab ntawm 8.5-9, uas txhais tau tias nag lossis daus, ces impurities raug tshem tawm. Cov tshuaj purified neutral calcium chloride yog preheated rau 172-174, thiab cov crystals tau tom qab txias yog flaky calcium chloride, uas tsis tshua muaj siv.
