Sodium Carbonate Txheej txheem cej luam

Soda tshauv, tshuaj hu ua anhydrous sodium carbonate, nrog cov mis mos molecularNaCO, feem ntau hu ua dej qab zib. Txawm hais tias hu ua "soda", nws tsis yog alkali; Hloov chaw, nws yog ib qho yooj yim inorganic carbonate raw khoom, dubbed "Niam ntawm Kev Lag Luam Tshuaj" hauv kev lag luam. Ntawm qhov kub thiab txias, nws zoo li cov hmoov dawb lossis granules, tsis muaj ntxhiab tsw, thiab nws cov kua dej yog alkaline. Nws nta zoo tshuaj ruaj khov, decomposes ntawm qhov kub thiab txias, thiab nws nquag nqus dej thiab caking.

Muab faib los ntawm ntau qhov ntom ntom, nws poob rau hauv ob pawg loj: lub teeb soda tshauv thiab ntom soda tshauv. Lawv sib xyaw cov tshuaj sib xyaw ua ke thiab sib txawv tsuas yog hauv particle morphology, bulk ntom, flowability thiab dusting zog. Kuj tseem muaj cov qib sub suav nrog qib zaub mov thiab tshuaj-reagent-qib. Dav siv nyob rau hauv iav tsim, tshuaj siv niaj hnub, kev kho dej, metallurgy, papermaking, zaub mov ua thiab lwm yam lag luam, nws nyob rau hauv lub ntiaj teb no cov lag luam feem ntau cov khoom siv tshuaj.
