Acide Boric

ibisobanuro bigufi:

Nifu ya kirisiti yera, ifite ibyiyumvo byoroshye kandi nta mpumuro nziza.Inkomoko ya acide ntabwo ari ugutanga proton yonyine.Kuberako boron ari atom ibura electron, irashobora kongeramo hydroxide ion ya molekile zamazi hanyuma ikarekura proton.Kwifashisha uyu mutungo wabuze electron, ibice bya polyhydroxyl (nka glycerol na glycerol, nibindi) byongeweho kugirango bibe ibintu bihamye kugirango bongere aside.

Acide ya Oxalic ni aside idakomeye.Itondekanya rya mbere ionisation ihoraho Ka1 = 5.9 × 10-2 hamwe na kabiri ya ionisiyoneri ihoraho Ka2 = 6.4 × 10-5.Ifite aside.Irashobora gutesha agaciro ishingiro, guhindura ibara, no kurekura karuboni ya dioxyde de carbone.Ifite kugabanuka gukomeye kandi biroroshye guhinduka okiside muri karuboni ya dioxyde de carbone namazi ukoresheje okiside.Acide potassium permanganate (KMnO4) irashobora guhinduka ibara hanyuma ikagabanuka kugeza kuri 2-valence manganese ion.

Imikoreshereze y'ibicuruzwa

Ikirahure / fiberglass

Ikoreshwa mugukora ibirahuri bya optique, ikirahure kirwanya aside, ikirahuri cya organoborate nibindi birahure hamwe nibirahure bya fibre, birashobora kunoza ubushyuhe no gukorera mu kirahure, kunoza imbaraga za mashini, kugabanya igihe cyo gushonga.B2O3 ifite uruhare runini rwa flux no gushiraho imiyoboro mugukora ibirahuri nibirahure.Kurugero, mubikorwa bya fibre fibre, ubushyuhe bwo gushonga burashobora kugabanuka kugirango byoroshye gushushanya insinga.Muri rusange, B2O3 irashobora kugabanya ubukonje, kugenzura iyaguka ryumuriro, gukumira ubwikorezi, kunoza imiti, no kunoza uburyo bwo guhangana nubukanishi hamwe nubushyuhe bwumuriro.Mu gukora ibirahuri aho hakenewe sodium nkeya, aside ya boric ikunze kuvangwa na sodium borate (nka borax pentahydrate cyangwa borax anhydrous) kugirango igabanye igipimo cya sodium-boron mu kirahure.Ibi nibyingenzi kubirahuri bya borosilike kuko okiside ya boron yerekana gukomera neza mugihe cya sodium nkeya na aluminium nyinshi.

Enamel / ceramic

Enamel, inganda zubutaka kugirango zivemo glaze, zirashobora kugabanya kwaguka kwubushyuhe bwumuriro wa glaze, kugabanya ubushyuhe bwo gukiza bwa glaze, kugirango birinde gucika no kwangirika, kunoza urumuri nubwihuta bwibicuruzwa.Kuri glaze ceramic na enamel, boride oxyde ni flux nziza kandi ikora umubiri.Irashobora gukora ikirahure (ku bushyuhe buke), igahindura uburyo bwo guhuza imiterere yubusa, kugabanya ubukonje nubushyuhe bwo hejuru, kunoza indangagaciro zivunika, kunoza imbaraga zumukanishi, kuramba no kwambara, ni ikintu cyingenzi cyumucyo utagira isasu.Amavuta maremare ya boron yeze vuba kandi akora glaze yoroshye vuba, ifasha amabara.Muri firime yihuta cyane, B2O3 itangizwa nka acide boric kugirango sodium ikenewe.

Inganda zita ku buzima

Ikoreshwa mugukora amavuta ya acide ya boric, disinfectant, astringent, preservative nibindi.

Flame retardant

Ongeraho borate kubintu bya selileide birashobora guhindura reaction ya okiside kandi bigateza imbere "carbone".Ntabwo rero ari flame retardant.Acide Boric, yonyine cyangwa ifatanije na borax, igira ingaruka zidasanzwe mukugabanya gucana umuriro wa selileide, ibiti, nipine yipamba muri matelas.

Metallurgie

Ikoreshwa nk'inyongera na cosolvent mugukora ibyuma bya boron kugirango ibyuma bya boron bigire ubukana bwinshi kandi bihindagurika neza.Acide Boric irashobora gukumira okiside yo hejuru yo gusudira ibyuma, gusya no gusudira.Nibikoresho fatizo bya ferroboron.

Inganda zikora imiti

Ikoreshwa mukubyara borat zitandukanye, nka sodium borohydride, borate ammonium hydrogen borate, kadmium borotungstate, potasiyumu borohydride nibindi.Mu musaruro wa nylon umuhuza, acide boric igira uruhare runini mu okiside ya hydrocarbone kandi ikabyara esters kugirango yongere umusaruro wa Ethanol, bityo bikarinda gukomeza okiside yitsinda rya hydroxyl kugirango ikore ketone cyangwa acide hydroxic.Inganda zifumbire mvaruganda zitanga buji, boron irimo ifumbire.Ikoreshwa nka analytique yimiti igamije gutegura buffer nibitangazamakuru bitandukanye byo korora haploid.
