Mtengo Wabwino Wopanga Sodium Sesqui Carbonate CAS：533-96-0

kufotokozera mwachidule:

Sodium Sesqui Carbonate, dzina lina, ndi sodium wa sodium carbonate, semi-alkali, ndipo fomula ya molekyulu ndi NA2CO3 · NAHCO3 · 2H2O. Sodium ya bicarbonate ndi mankhwala a makhiristo oyera ngati singano, ufa wonga pepala kapena kristalo. Kulemera kwa mamolekyulu ndi 226.03, ndipo kuchuluka kwake ndi 2.112. Pa 100 ° C, ndi 42%. Yankho lamadzi ndi la alkaline, ndipo alkali yake ndi yofooka kuposa sodium carbonate. Imapangidwa ndi gawo lina la sodium carbonate ndi sodium bicarbonate solution.

Makhalidwe: Sodium Sesqui Carbonate ndi kristalo woyera wooneka ngati singano, wofanana ndi pepala kapena ufa wa kristalo. Kuchuluka kwake ndi 2.112, komwe sikophweka kupirira. Pa 42% pa ° C, yankho lamadzi ndi la alkaline, ndipo sodium bicarbonate ndi yofooka kuposa sodium carbonate.

Kugwiritsa Ntchito Sodium Sesqui Carbonate

Amagwiritsidwa ntchito mu mchere wosambira ndi mankhwala, mankhwala ophera alkali pachikopa chofiirira, kufewetsa madzi, dziwe losambira ndi madzi amchere, zowonjezera zotsukira zovala, zosakaniza zazikulu zotsukira mafakitale, zosakaniza zazikulu zotsukira pamwamba pa nthaka yolimba, nsalu yooneka ngati chifaniziro, utoto wa tsitsi, zowonjezera zotsukira (zotsukira ubweya, ndi zina zotero), zowonjezera zotsukira zinyalala za m'mizinda ndi m'matauni; Zoyenera kutsuka mitundu yonse, kuchotsa kuipitsidwa ndi kutsuka zomwe zimafuna kugwiritsa ntchito zinthu zopanda alkaline (kaya sopo ikufunika kapena ayi). M'zaka zaposachedwa, monga mtundu watsopano wa mchere wosambira umagwiritsidwa ntchito kwambiri ku Japan ndi South Korea.

Kufotokozera kwa Sodium Sesqui Carbonate

Pawiri	Kufotokozera

Njira ya Sodium Sesqui Carbonate: pogwiritsa ntchito njira yachilengedwe ya alkali. Choyamba phwanyani miyala yachilengedwe ya alkali kukhala granularity inayake (pafupifupi 0.8mm). Pambuyo posungunuka, kuyeretsa, ndikusefa, kuchuluka kwa zinthu zothandizira makristalo (monga sodium alkyl sulfate, ndi zina zotero), chinthu chopangira thovu chachilengedwe ndi chinthu chopangira sedimentary zimawonjezedwa ku filtrate. Dikirani, titatha kutulutsa makristalo ndi kulekanitsa madzi, titha kupeza makeke awiri a sodium sodium carbonate omwe alibe zonyansa zachilengedwe. Keke yopezera ndalama imatha kusungunuka kwambiri, kusungunuka ndi kuuma, ndikupeza zinthu zochulukitsa za sodium carbonate, zomwe zimagwiritsidwa ntchito pochiza kapena kupanga madzi. Makeke owotcha a sodium carbonate amatha kutenthedwa kutentha kosiyanasiyana (pafupifupi 200 ° C mpaka 850 ° C) amatha kupeza zinthu zolemera zokhala ndi kuchuluka kosiyanasiyana (0.8 ～ 1.0g/cm3).
