SHILIAN Soda tshauv Dense Sodium Carbonate
Khoom Taw Qhia
Hnyav soda tshauv yog lub teeb dej qab zib tshauv los ntawm hydration (nce ntawm cov dej crystallizing), nws qhov ntom, ntim qib siab dua li lub teeb.Cov ntsiab lus thiab ntsev ntawm soda tshauv tuaj yeem muab faib ua ob hom, hnyav thiab lub teeb.Nyob rau hauv lub teb chaws tus qauv tam sim no rau dej qab zib tshauv, ntsev cov ntsiab lus ntawm cov khoom siv sodium carbonate zoo heev yog tsawg dua los yog sib npaug li 0.7%, uas yog, hnyav soda tshauv, thiab qhov ceev ntawm hnyav soda tshauv yog 1000-1200kg / m3.
