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

Kufotokozera mwachidule:

Sodium Sesqui Carbonate, alias, ndi sodium wa sodium carbonate, semi-alkali, ndipo mawonekedwe a molekyulu ndi NA2CO3 · NAHCO3 · 2H2O. Bicarbonate sodium ndi mankhwala a singano zoyera ngati makhiristo, pepala-ngati kapena crystalline ufa. Mamolekyu achibale ndi 226.03, ndipo kachulukidwe kachibale ndi 2.112. Pa 100 ° C, ndi 42%. Njira yamadzimadzi ndi yamchere, ndipo alkali yake ndi yofooka kuposa sodium carbonate. Amapangidwa ndi gawo lina la sodium carbonate ndi sodium bicarbonate solution.

Maonekedwe: Sodium Sesqui Carbonate ndi galasi loyera ngati singano, ngati pepala kapena ufa wa crystalline. Kachulukidwe kachibale ndi 2.112, komwe sikophweka nyengo. Pa 42% pa ° C, njira yamadzimadzi imakhala yamchere, ndipo sodium bicarbonate ndi yofooka kuposa sodium carbonate.

Kugwiritsa ntchito Sodium Sesqui Carbonate

Ntchito mchere osamba ndi mankhwala, alkali wothandizila mu zikopa tanned, kufewetsa madzi, dziwe losambira ndi mchere madzi recuperation, zovala zotsukira zowonjezera, zosakaniza waukulu wa wothandizila mafakitale kutsukidwa, zosakaniza waukulu wa zovuta pamwamba kuyeretsa wothandizila chifaniziro nsalu, tsitsi utoto, kutsuka (ubweya rinsing, etc.) zina zowonjezera, m'mizinda ndi chakudya cham'madzi zowonjezera; Oyenera kuchapa mitundu yonse, kuyeretsa ndi kukolopa zomwe zimafuna kugwiritsa ntchito zinthu zofooka za alkaline (kaya sopo akufunika kapena ayi). M'zaka zaposachedwa, monga mtundu watsopano wa mchere wosambira umagwiritsidwa ntchito kwambiri ku Japan ndi South Korea.

Njira ya sodium Sesqui Carbonate: mu njira ya alkali yachilengedwe. Choyamba thyola miyala yachilengedwe ya alkali kukhala granularity (pafupifupi 0.8mm). Pambuyo pa kusungunuka, kulongosola, ndi kusefa, zowonjezera zowonjezera za kristalo (monga sodium alkyl sulfate, etc.), organic foaming agent ndi sedimentary agent amawonjezeredwa ku filtrate. Dikirani, pambuyo evaporation makhiristo ndi mayi madzi kulekana, tikhoza kupeza iwiri sodium carbonate fyuluta chofufumitsa kuti mulibe zosafunika inorganic. Keke yopeza ndalama imatha kusungunuka kwambiri, makhiristo ndi kuuma, ndikupeza zinthu zambiri za sodium carbonate, zomwe zimagwiritsidwa ntchito popangira madzi kapena kupanga. Kuwotcha makeke a sodium carbonate fyuluta akhoza kuwotchedwa pa kutentha kosiyana (pafupifupi 200 ° C mpaka 850 ° C) angapeze mankhwala mulu wolemera ndi kachulukidwe osiyanasiyana kudzikundikira (0.8 ~ 1.0g/cm3).
