I-sodium bicarbonate

incazelo emfushane:

Ingxube ye-inorganic, i-crystalline powder emhlophe, ayinaphunga, inosawoti, inyibilika emanzini.Ibola kancane kancane emoyeni onomswakama noma emoyeni oshisayo, ikhiqize i-carbon dioxide, ebole ngokuphelele lapho ishisa ku-270 ° C. Uma ibhekene ne-asidi, ibhidliza kakhulu, ikhiqize i-carbon dioxide.

I-sodium bicarbonate iyikristalu emhlophe, noma i-opaque monoclinic crystal system ikristale enhle, ayinaphunga, inosawoti futhi ipholile, incibilika kalula emanzini ne-glycerol, ayincibiliki ku-ethanol.Ukuncibilika emanzini ngu-7.8g (18℃), 16.0g (60 ℃), ukuminyana ngu-2.20g/cm3, amandla adonsela phansi athile ngu-2.208, kanye nenkomba ye-refractive ithi α : 1.465.β : 1.498;γ : 1.504, i-entropy ejwayelekile 24.4J/(mol·K), ukushisa kokwakheka kwe-229.3kJ/mol, ukushisa kwesisombululo 4.33kJ/mol, umthamo wokushisa othize (Cp).20.89J/(mol·°C)(22°C).

Ukusetshenziswa komkhiqizo

Okokuhlanza

1, i-alkalization:i-sodium bicarbonate lotion iyi-alkali, ingakwazi ukwenza izinto ezine-asidi ingabi namandla, ikhulise inani le-pH yendawo, idlale indima ye-alkalization.Lokhu kudlala indima ebalulekile ekugubheni nasekunciphiseni ukucasuka kwe-asidi, ukushiswa kwe-asidi, noma izixazululo ze-asidi.

2, ukuhlanza nokuhlanza:I-sodium bicarbonate lotion ingasetshenziswa ukuhlanza nokukhipha amanxeba, amanxeba noma ezinye izindawo ezingcolile.Kungasiza ukususa ukungcola, amagciwane, ubuthi nezinye izinto eziyingozi, kukhuthaze ukuphulukiswa kwesilonda futhi kunciphise ingozi yokutheleleka.

3, umphumela we-antibacterial:ngenxa yezakhiwo zayo ze-alkali, i-sodium bicarbonate lotion inganikeza izinga elithile lomphumela we-antibacterial, futhi inomphumela ovimbelayo kwamanye amagciwane kanye nesikhunta.Ngaphezu kwalokho, i-sodium bicarbonate lotion ingabamba iqhaza ekuxubeni, ekuncibilikiseni noma ekulawuleni inani le-pH ekusebenzisaneni kweminye imithi ukuze kuthuthukiswe umphumela wezidakamizwa noma kuthuthukiswe ukuzinza kwazo.

Ukwengeza ukudaya

Ingasetshenziswa njenge-ejenti yokulungisa yokudaya ukuphrinta, isigcinalwazi se-asidi-alkali, kanye ne-ejenti yokwelapha yangemuva yokudaya kwendwangu nokuqeda.Ukwengeza i-baking soda ekudayeni kungavimbela intambo ekukhiqizeni izimbali ezinemibala.

I-ejenti yokukhulula (ibanga lokudla)

Ekucubunguleni ukudla, i-sodium bicarbonate ingenye yezinto ezisetshenziswa kakhulu zokukhulula, ezisetshenziswa ekukhiqizeni amabhisikidi, isinkwa, njll., kodwa ngemva kwesenzo kuzohlala i-sodium carbonate, ukusetshenziswa kakhulu kuzokwenza ukuthi ukudla kwe-alkalinity kukhulu kakhulu futhi kuholele. ukunambitheka okubi, umbala onsundu ophuzi.Ingumkhiqizi we-carbon dioxide eziphuzweni ezithambile;Ingahlanganiswa ne-alum yenze i-alkaline baking powder, futhi ingahlanganiswa nomlotha wesoda ukwenza i-alkali yamatshe omphakathi.Ingasetshenziswa futhi njengesilondolozi sebhotela.Ekucutshungulweni kwemifino kungasetshenziswa njenge-ejenti yokuvikela umbala wezithelo nemifino.Ukwengeza cishe u-0.1% kuya ku-0.2% we-sodium bicarbonate lapho ugeza izithelo nemifino kungenza ukuzinza okuluhlaza.Lapho i-sodium bicarbonate isetshenziswa njenge-ejenti yokwelapha izithelo nemifino, inani le-pH lezithelo nemifino lingakhuphuka, ukugcinwa kwamanzi kwamaprotheni kungathuthukiswa, amangqamuzana ezicubu zokudla angathanjiswa, futhi izingxenye ezibulalayo zingancibilika.Ngaphezu kwalokho, kunomphumela wokukhipha iphunga lobisi lwezimvu, futhi inani lokusetshenziswa liyi-0.001% kuya ku-0.002%.
