I-Boric Acid

inkcazelo emfutshane:

Ingumgubo omhlophe wekristale, enemvakalelo egudileyo kwaye akukho vumba.Umthombo wayo oneasidi ayikuko ukunika iiproton ngokwayo.Ngenxa yokuba i-boron i-athomu enqongopheleyo ye-electron, inokongeza ii-ion ze-hydroxide ze-molecule zamanzi kunye nokukhulula iiprotoni.Ukuthatha inzuzo yale propati ye-electron-deficient, i-polyhydroxyl compounds (efana ne-glycerol kunye ne-glycerol, njl.) yongezwa ukwenza ii-complexes ezizinzileyo zokuqinisa i-asidi yazo.

Ukusetyenziswa kweMveliso

Iglasi / i-fiberglass

Isetyenziselwa ukuveliswa kweglasi ye-optical, iglasi enganyangekiyo ye-asidi, iglasi ye-organoborate kunye nezinye iiglasi eziphambili kunye nefiber yeglasi, inokuphucula ukumelana nobushushu kunye nokungafihli kweglasi, ukuphucula amandla omatshini, ukunciphisa ixesha lokunyibilika.I-B2O3 idlala indima emibini yokuguquguquka kunye nokwakhiwa kwenethiwekhi ekwenzeni iglasi kunye nefiber yeglasi.Umzekelo, kwimveliso yefiber yeglasi, ubushushu obunyibilikayo bunokuthotywa ukuququzelela umzobo wocingo.Ngokubanzi, i-B2O3 inokunciphisa i-viscosity, ilawule ukwanda kwe-thermal, ithintele ukugqithiswa, iphucule ukuzinza kweekhemikhali, kunye nokuphucula ukuchasana nokutshatyalaliswa komatshini kunye nokutshatyalaliswa kwe-thermal.Kwimveliso yeglasi apho kufunwa i-sodium ephantsi, i-boric acid idla ngokuxutywa kunye ne-sodium borates (efana ne-borax pentahydrate okanye i-borax anhydrous) ukulawula umlinganiselo we-sodium-boron kwiglasi.Oku kubalulekile kwiglasi ye-borosilicate kuba i-boron oxide ibonisa ukunyibilika kakuhle kwimeko ye-sodium ephantsi kunye ne-aluminium ephezulu.

I-enamel / i-ceramic

I-enamel, imboni ye-ceramic yokuvelisa i-glaze, inokunciphisa ukwanda kwe-thermal ye-glaze, ukunciphisa ubushushu bokunyanga be-glaze, ukwenzela ukuba kuthintelwe ukuqhekeka kunye ne-deglazing, ukuphucula ukukhanya kunye nokukhawuleza kweemveliso.Kwi-ceramic kunye ne-enamel glazes, i-boron oxide yi-flux efanelekileyo kunye nomzimba wokwenza inethiwekhi.Iyakwazi ukwenza iglasi (kwiqondo lokushisa eliphantsi), iphucule ukulungelelaniswa kwe-glaze engenanto, ukunciphisa i-viscosity kunye noxinzelelo lwe-surface, ukuphucula i-index refractive index, ukuphucula amandla omatshini, ukuqina kunye nokumelana nokugqoka, yinto ebalulekileyo ye-lead-free glaze.I-boron frit ephezulu ivuthwa ngokukhawuleza kwaye yenza i-glaze egudileyo ngokukhawuleza, ehambelana nombala.Kwi-tile ye-glazed tile frit ngokukhawuleza, i-B2O3 ifakwe njenge-boric acid ukuqinisekisa imfuno ephantsi ye-sodium.

Ishishini lokhathalelo lwempilo

Isetyenziselwa ukuveliswa kwe-boric acid ointment, i-disinfectant, i-astringent, i-preservative kunye nokunye.

Ukubuyiswa komlilo

Ukongeza i-borate kwi-celluloid material inokutshintsha i-oxidation reaction yayo kwaye ikhuthaze ukubunjwa kwe "carbonization".Ngoko ke iyanqanda amadangatye.Iasidi yeboric, iyodwa okanye idityaniswe neborax, inefuthe elikhethekileyo ekunciphiseni ukutsha kwe-celluloid insulation, iinkuni, kunye namatayara ekotoni kumatrasi.

Isinyithi

Isetyenziswa njengezongezelelo kunye ne-cosolvent kwimveliso yentsimbi ye-boron ukwenza intsimbi ye-boron ibe nobunzima obuphezulu kunye ne-ductility elungileyo yokuqengqeleka.I-asidi ye-boric inokuthintela i-oxidation yomhlaba we-welding yensimbi, ukubethelwa kunye ne-casing welding.Ikwayinto ekrwada ye-ferroboron alloy.

Ishishini lemichiza

Isetyenziselwa ukuveliswa kweebhorati ezahlukeneyo, ezifana ne-sodium borohydride, i-ammonium hydrogen borate, i-cadmium borotungstate, i-borohydride ye-potassium kunye nokunye.Kwimveliso ye-nylon intermediates, i-asidi ye-boric idlala indima ye-catalytic kwi-oxidation ye-hydrocarbons kwaye ivelise i-esters ukunyusa isivuno se-ethanol, ngaloo ndlela ithintela i-oxidation eyongezelelweyo yamaqela e-hydroxyl ukuvelisa i-ketones okanye i-hydroxic acids.Imboni yezichumisi yokuveliswa kweentambo zekhandlela, i-boron equlethe isichumisi.Isetyenziselwa ukuhlalutya i-reagent yekhemikhali yokulungiselela i-buffer kunye neendaba ezahlukeneyo zokuzalanisa i-haploid.
