I-EVERBRIGHT® 'izophinde ihlinzeke ngezifiso:

okuqukethwe/ubumhlophe/usayizi wezinhlayiya/PHvalue/umbala/isitayela sokupakisha/ imininingwane yokupakisha

kanye neminye imikhiqizo ethile ekufanele kakhulu izimo zakho zokusebenzisa , futhi ikunikeze amasampuli amahhala.

IMINININGWANE YOMKHIQIZO

I-Oxalic acid iyi-asidi ebuthakathaka.I-ionization ye-oda lokuqala engaguquki Ka1=5.9×10-2 kanye ne-ionization ye-oda lesibili njalo Ka2=6.4×10-5.Ine-asidi evamile.Inganciphisa isisekelo, ishintshe umbala inkomba, futhi ikhulule i-carbon dioxide ngokusebenzisana nama-carbonates.Isabela nge-oxidizing ejenti futhi ifakwa kalula kwi-carbon dioxide namanzi.Isixazululo se-Acid potassium permanganate (KMnO4) singashintsha umbala futhi sehliselwe ku-2-valence manganese ion.Ku-189.5℃ noma phambi kwe-concentrated sulfuric acid, izobola yakhe ikhabhoni dioxide, i-carbon monoxide namanzi.H2C2O4=CO2↑+CO↑+H2O.

UKUSETSHENZISWA KOMKHIQIZO

IBANGA LEZIMBUNDU

I-synthetic catalyst

Njenge-catalyst ye-phenolic resin synthesis, ukusabela kwe-catalytic kuthambile, inqubo izinzile uma kuqhathaniswa, futhi ubude besikhathi bude kakhulu.Isixazululo se-acetone se-oxalate singadala ukusabela okwelaphayo kwe-epoxy resin futhi sinciphise isikhathi sokuphulukisa.Ibuye isetshenziswe njengesilawuli se-pH sokuhlanganiswa kwe-urea-formaldehyde resin ne-melamine formaldehyde resin.Ingase futhi yengezwe ku-adhesive ye-polyvinyl formaldehyde encibilika emanzini ukuze kuthuthukiswe isivinini sokumisa namandla okubopha.Ibuye isetshenziswe njenge-ejenti elaphayo ye-urea-formaldehyde resin kanye ne-metal ion chelating agent.Ingasetshenziswa njenge-accelerant yokulungiselela isitashi esinamathelayo nge-oxidizer ye-KMnO4 ukusheshisa izinga le-oxidation kanye nokunciphisa isikhathi sokuphendula.

I-ejenti yokuhlanza

I-Oxalic acid ingasetshenziswa njenge-ejenti yokuhlanza, ikakhulukazi ngenxa yekhono layo lokuchelate (ukubopha) ama-ion amaningi ensimbi namaminerali, okuhlanganisa i-calcium, i-magnesium, i-aluminium, njll. Lokhu kwenzai-oxalic acidkulungele ikakhulukazi ukususa umcako kanye ne-limescale.

Ukuphrinta & ukudaya

Imboni yokunyathelisa nokudaya ingangena esikhundleni se-acetic acid ekwenzeni isisekelo esiluhlaza nokunye.Isetshenziswa njengomsizi wombala kanye ne-bleach odayi be-pigment.Ingahlanganiswa namakhemikhali athile ukwenza odayi, futhi ingasetshenziswa njengesiqinisi samadayi, ngaleyo ndlela yandise ukuphila kwamadayi.

Imboni yepulasitiki

Imboni yepulasitiki yokukhiqiza i-polyvinyl chloride, amapulasitiki amino, amapulasitiki e-urea-formaldehyde, ama-chips opende nokunye.

Imboni ye-Photovoltaic

I-Oxalic acid nayo isetshenziswa embonini ye-photovoltaic.I-Oxalic acid ingasetshenziswa ukwenza ama-wafers e-silicon amaphaneli elanga, okusiza ukunciphisa amaphutha ebusweni bamawafa.

Imboni yokuwasha isihlabathi

Ihlanganiswe ne-hydrochloric acid kanye ne-hydrofluoric acid, ingenza ngokugeza kwe-asidi yesihlabathi se-quartz.

Ukucubungula isikhumba

I-Oxalic acid ingasetshenziswa njenge-ejenti yokushuka enqubweni yokucubungula isikhumba.Iyakwazi ukungena emicu yesikhumba, iyenze izinze futhi ivimbele ukubola nokuqina.

Ukususwa kokugqwala

ingasusa ngokuqondile ukugqwala kwensimbi yengulube, insimbi engagqwali nezinye izinsimbi.
