I-Boric Acid

incazelo emfushane:

Impushana emhlophe ecwebezelayo, ezwakala kahle futhi engenaphunga.Umthombo wayo one-asidi awukona ukunikeza ama-proton ngokwawo.Ngenxa yokuthi i-boron iyi-athomu entula i-electron, ingakwazi ukwengeza i-hydroxide ion yama-molecule amanzi futhi ikhulule ama-proton.Ukusebenzisa lesi sakhiwo esingenawo ama-electron, izinhlanganisela ze-polyhydroxyl (njenge-glycerol ne-glycerol, njll.) zengezwa ukuze zenze izingxube ezizinzile ukuze kuqiniswe i-asidi yazo.

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.Ine-reducibility eqinile futhi kulula ukuthi ifakwe kwi-carbon dioxide nasemanzini nge-oxidizing agent.Isixazululo se-Acid potassium permanganate (KMnO4) singashintsha umbala futhi sehliselwe ku-2-valence manganese ion.

Ukusetshenziswa komkhiqizo

Ingilazi/fiberglass

Isetshenziselwa ukukhiqizwa kwengilazi ye-optical, ingilazi engamelana ne-asidi, ingilazi ye-organoborate nezinye ingilazi ethuthukisiwe kanye ne-glass fiber, ingathuthukisa ukumelana nokushisa nokubonakala kwengilazi, ithuthukise amandla emishini, inciphise isikhathi sokuncibilika.I-B2O3 idlala indima embaxambili yokuguquguquka kanye nokwakheka kwenethiwekhi ekwenzeni ingilazi ne-glass fiber.Isibonelo, ekukhiqizeni i-fiber yengilazi, izinga lokushisa elincibilikayo lingehliswa ukuze kube lula ukudweba ngocingo.Ngokuvamile, i-B2O3 inganciphisa i-viscosity, ilawule ukunwetshwa kokushisa, ivimbele ukungena, ithuthukise ukuqina kwamakhemikhali, futhi ithuthukise ukumelana nokushaqeka kwemishini nokushaqeka kokushisa.Ekukhiqizweni kwengilazi lapho kudingeka khona okuqukethwe kwe-sodium ephansi, i-boric acid ivamise ukuxutshwa ne-sodium borates (njenge-borax pentahydrate noma i-borax anhydrous) ukuze kulawulwe isilinganiso se-sodium-boron engilazini.Lokhu kubalulekile engilazini ye-borosilicate ngoba i-boron oxide ibonisa ukuncibilika okuhle esimweni se-sodium ephansi ne-aluminium ephezulu.

Koqweqwe lwawo / i-ceramic

Imboni ye-ceramic yokukhiqiza i-glaze, imboni ye-ceramic, inganciphisa ukwanda okushisayo kwe-glaze, inciphise izinga lokushisa lokuphulukisa le-glaze, ukuze kuvinjwe ukuqhekeka nokuwohloka, kuthuthukise ukucwebezela nokushesha kwemikhiqizo.Ngezicwebezelisi ze-ceramic kanye ne-koqweqwe lwawo, i-boron oxide iwukugeleza okuhle kanye nomzimba owenza inethiwekhi.Ingenza ingilazi (emazingeni okushisa aphansi), ithuthukise ukuguquguquka kwe-glaze engenalutho, inciphise i-viscosity kanye nokungezwani kwendawo, ithuthukise inkomba ye-refractive, ithuthukise amandla emishini, ukuqina nokumelana nokugqoka, iyisici esibalulekile se-glaze engenamthofu.I-boron frit ephezulu ivuthwa ngokushesha futhi yakhe i-glaze ebushelelezi ngokushesha, evumelana nombala.Kuthayela elicwebezelisiwe elivutha ngokushesha, i-B2O3 yethulwa njenge-boric acid ukuze kuqinisekiswe imfuneko ephansi yokuqukethwe kwe-sodium.

Imboni yokunakekelwa kwezempilo

Isetshenziselwa ukukhiqizwa kwe-boric acid wamafutha, isibulala-magciwane, i-astringent, i-preservative nokunye.

I-flame retardant

Ukwengeza i-borate ku-celluloid material kungashintsha ukusabela kwayo kwe-oxidation futhi kukhuthaze ukwakheka "kwe-carbonization".Ngakho-ke iyanqanda amalangabi.I-boric acid, iyodwa noma ihlanganiswe ne-borax, inomthelela okhethekile ekwehliseni ukuvutha kwe-celluloid insulation, amathayi okhuni, nokotini kumatilasi.

I-Metallurgy

Isetshenziswa njengesengezo kanye ne-cosolvent ekukhiqizeni insimbi ye-boron ukwenza insimbi ye-boron ibe nobulukhuni obuphezulu kanye ne-ductility enhle yokugingqa.I-Boric acid ingavimbela i-oxidation engaphezulu ye-welding yensimbi, i-brazing kanye ne-casing welding.Kubuye kube yimpahla eluhlaza ye-ferroboron alloy.

Imboni yamakhemikhali

Isetshenziselwa ukukhiqizwa kwe-borates ehlukahlukene, njenge-sodium borohydride, i-ammonium hydrogen borate, i-cadmium borotungstate, i-potassium borohydride nokunye.Ekukhiqizeni izinto ezimaphakathi zenayiloni, i-boric acid idlala indima ebambekayo ekufakweni kwe-oxidation yama-hydrocarbon futhi ikhiqize ama-ester ukuze kwandiswe isivuno se-ethanol, ngaleyo ndlela kuvimbele ukuqhubekela phambili kwe-oxidation yamaqembu e-hydroxyl ukukhiqiza ama-ketone noma ama-hydroxic acid.Imboni kamanyolo yokukhiqiza izibani zamakhandlela, i-boron equkethe umanyolo.Isetshenziswa njenge-reagent yamakhemikhali yokuhlaziya yokulungiselela isigcinalwazi kanye nemidiya ehlukahlukene yokuzalanisa i-haploid.
