umxholo/ubumhlophe/ubungakanani besuntswana/PHvalue/umbala/isimbo sokupakisha/ ukupakishwa kweenkcukacha

kunye nezinye iimveliso ezithile ezifanelekileyo ngakumbi kwiimeko zakho zokusebenzisa, kwaye unikeze iisampuli zasimahla.

IINKCUKACHA ZEMVELISO

I-Oxalic acid yi-asidi ebuthathaka.Umyalelo wokuqala we-ionization rhoqo Ka1 = 5.9 × 10-2 kunye ne-ionization yomyalelo wesibini rhoqo Ka2 = 6.4 × 10-5.Ineasidi eqhelekileyo.Iyakwazi ukunciphisa isiseko, i-discolor isalathisi, kwaye ikhulule i-carbon dioxide ngokusebenzisana ne-carbonates.Isebenza nge-oxidizing agents kwaye ikhutshwa lula kwicarbon dioxide namanzi.Isisombululo se-Acid potassium permanganate (KMnO4) sinokuguqulwa sibe yi-2-valence manganese ion.Kwi-189.5 ℃ okanye phambi kwe-asidi ye-sulfuric egxininisiweyo, iya kubola ukuze yenze i-carbon dioxide, i-carbon monoxide kunye namanzi.H2C2O4=CO2↑+CO↑+H2O.

UKUSETYENZISWA KWEMVELISO

UHLELO LOMZIMBA

I-Synthetic catalyst

Njenge-catalyst ye-phenolic resin synthesis, i-catalytic reaction ithambile, inkqubo izinzile, kwaye ubude bexesha elide kakhulu.Isisombululo se-acetone ye-oxalate sinokubangela ukusabela kokunyanga kwe-epoxy resin kunye nokunciphisa ixesha lokunyanga.Ikwasetyenziswa njengolawulo lwe-pH yokwenziwa kweresin ye-urea-formaldehyde kunye ne-melamine formaldehyde resin.Isenokongezwa kwi-adhesive ye-polyvinyl formaldehyde enyibilikayo emanzini ukuphucula isantya sokumisa kunye namandla okudibanisa.Ikwasetyenziswa njenge-ejenti yokunyanga i-urea-formaldehyde resin kunye ne-agent yensimbi ye-ion chelating.Ingasetyenziswa njenge-accelerant yokulungiselela isitashi sokuncamathelisa nge-KMnO4 oxidizer ukukhawulezisa izinga le-oxidation kunye nokunciphisa ixesha lokuphendula.

I-arhente yokucoca

I-asidi ye-oxalic ingasetyenziselwa njenge-arhente yokucoca, ngokukodwa ngenxa yokukwazi ukutshisa (ukubopha) i-ion ezininzi zetsimbi kunye neeminerali, kuquka i-calcium, i-magnesium, i-aluminium, njl.i-oxalic acidilungele ngokukodwa ukususa ikalika kunye ne-limescale.

Ukuprinta & ukudaya

Umzi-mveliso wokushicilela kunye nokudaya unokutshintsha i-acetic acid ukuze kwenziwe isiseko esiluhlaza njalo njalo.Isetyenziswa njengoncedo lombala kunye neblitshi kwiidayi zepigment.Inokudibaniswa kunye neekhemikhali ezithile ukwenza idayi, kwaye ingasetyenziselwa ukuzinzisa idayi, ngaloo ndlela yandisa ubomi bedayi.

Ishishini leplastiki

Imboni yeplastiki yokuvelisa i-polyvinyl chloride, iiplastiki ze-amino, iiplastiki ze-urea-formaldehyde, iitshiphu zepeyinti kunye nokunye.

Ushishino lwefotovoltaic

I-Oxalic acid iphinda isetyenziswe kwishishini le-photovoltaic.Iasidi ye-oxalic ingasetyenziselwa ukwenza ii-silicone wafers kwiipaneli zelanga, inceda ukunciphisa iziphene kumphezulu we-wafers.

Ishishini lokuhlamba isanti

Idibaniswe ne-hydrochloric acid kunye ne-hydrofluoric acid, inokusebenza kwi-asidi yokuhlamba isanti ye-quartz.

Ukwenziwa kwesikhumba

I-asidi ye-oxalic ingasetyenziswa njenge-agent yokutshisa kwinkqubo yokwenziwa kwesikhumba.Iyakwazi ukungena kwimicu yesikhumba, iyenze ibe yizinzile kwaye ikhusele ukubola kunye nokuqina.

Ukususwa komhlwa

inokususa ngokuthe ngqo umhlwa wentsimbi yehagu, intsimbi engatyiwayo kunye nezinye iintsimbi.
