I-Sodium Bicarbonate
I-sodium bicarbonate, ifomula yamakhemikhali: I-NaHCO₃, eyaziwa kakhulu ngokuthi i-baking soda, amakristalu amhlophe amahle, i-alkaline powder emhlophe encibilika kalula emanzini, akukho shintsho emoyeni owomile, ibola kancane kancane emoyeni omanzi ukuze ikhiphe i-carbon dioxide.
I-sodium bicarbonate ingasetshenziswa ngqo njengezinto zokusetshenziswa embonini yezemithi ekwelapheni i-hyperacidity. Ingasetshenziswa futhi ekukhiqizweni kwamafilimu, ekushiseni isikhumba, ekucubunguleni amaminerali, ekuncibilikiseni, ekwelapheni ukushisa kwensimbi, kanye nasezimbonini zefayibha nerabha. Ngesikhathi esifanayo, isetshenziswa njengesihlanzi soboya, kanye nasekucwilisweni kwembewu yezolimo.
Isetshenziselwani i-sodium bicarbonate?
Ekucubungulweni kokudla, i-sodium bicarbonate iyindlela esetshenziswa kakhulu yokuqoqa ukudla, esetshenziselwa ukukhiqiza amabhisikidi, isinkwa, njll., kodwa i-sodium carbonate izosala ngemva kokusebenza.
Ukusetshenziswa kakhulu kuzokwenza ukudla kube ne-alkaline kakhulu futhi kubangele ukuthi ukunambitheka kubole.
Umbala onsundu ophuzi. Kungumkhiqizi we-carbon dioxide eziphuzweni ezibandayo; kungahlanganiswa ne-alum ukuze kwakhiwe i-alkaline baking powder, futhi kungahlanganiswa ne-soda ash ukuze kwakhiwe i-civil litholine; kungasetshenziswa futhi njengesivikelo sebhotela. Ekucubungulweni kwemifino, kungasetshenziswa njengento yokugcina umbala wezithelo nemifino.
Uma ugeza izithelo nemifino, ukwengeza cishe i-sodium bicarbonate engu-0.1% ~ 0.2% kungenza umbala oluhlaza uqine.
Uma i-sodium bicarbonate isetshenziswa njenge-ejenti yokwelapha izithelo nemifino, ngokubilisa nokufiphaza izithelo nemifino, inani le-pH yezithelo nemifino lingakhushulwa, amandla okugcina amanzi eprotheni angakhushulwa, ukuthamba kwamaseli ezicubu zokudla kungathuthukiswa, futhi izingxenye ezibangela ukungezwani komzimba zingancibilikiswa. Ngaphezu kwalokho, inomphumela wokususa inyama yemvu obisini lwembuzi, futhi umthamo u-0.001% ~ 0.002%.
Ukusetshenziswa komkhiqizo
Isetshenziswa kakhulu njengesithako sokudla embonini yokudla, izithasiselo zokudla zezilwane, i-ejenti yokwenza amagwebu embonini yerabha. Isithako esihlanganisayo ekwenzeni insipho, insipho yokwenza ama-movie e-Carbon Dioxide (CO2) reactor ebhiya, eziphuzweni, njll.
1. Njenge-rasing agent, i-neutralizer kanye ne-dough improver, i-NaHCO3 ingasetshenziswa kuma-pastry futhi ingasetshenziswa ngokufanele ngokwezidingo zokukhiqiza;
2. Insimu yokudla: I-sodium bicarbonate isetshenziswa ekukhuliseni izinhlanzi ukuze kulungiswe inani le-PH lamanzi echibini; Isetshenziswa njengokudla kwezinkukhu namadada;
3. I-baking soda ingasetshenziswa ekuhlanzeni indlu;
4. Embonini yerabha, isetshenziswa ekukhiqizeni irabha neziponji;
5. Embonini yokunyathelisa nokudaya, i-baking soda isetshenziswa njenge-ejenti yokulungisa ukudaya nokunyathelisa, i-acid-base buffer;
6. Emishinini yokulwa nomlilo, i-baking soda isetshenziswa ekukhiqizeni iziqhumisi.
1. Iminyaka engaphezu kwengu-10 yesipiliyoni nge-ISO eqinisekisiwe,
2. Ifektri yokuxuba ukunambitheka kanye noshukela, iTianjia Own Brands,
3. Ucwaningo mayelana nolwazi lwemakethe kanye nokulandelela izitayela,
4. Ukulethwa Ngesikhathi Esifanele kanye Nokukhushulwa Kwesitoko emikhiqizweni eshisayo edinga kakhulu,
5. Ithembekile futhi ilandele ngokuqinile umthwalo wenkontileka kanye nensizakalo yokuthengisa ngemuva,
6. Ochwepheshe kwi-International Logistic Service, imibhalo yokuqinisekisa ukuthi izinto zisebenza ngokusemthethweni kanye nenqubo yokuhlola yeqembu lesithathu.
