Boric Acid

tsananguro pfupi:

Iyo ichena crystalline poda, ine manzwiro akatsetseka uye isina kunhuwa.Yayo acidic sosi haisi yekupa proton pachayo.Nekuti boron is atomu isina erekitironi, inogona kuwedzera hydroxide ions yemamorekuru emvura uye kuburitsa mapurotoni.Kutora mukana weiyi electron-deficient property, polyhydroxyl compounds (yakadai se glycerol uye glycerol, nezvimwewo) inowedzerwa kuti iite zvigadziriswe zvakagadzikana kusimbisa acidity yavo.

Anhydrous crystal(zviri mukati ≥99%)

Monohydrate crystal(zvirimo ≥98%)

(Scope yereferensi yekushandisa 'chigadzirwa kushandiswa')

Oxalic acid iasidhi isina simba.Yekutanga-odha ionization inogara Ka1 = 5.9 × 10-2 uye yechipiri-yekurongeka ionization inogara Ka2 = 6.4 × 10-5.Iine acid commonness.Inogona kukanganisa chigadziko, discolor chiratidzo, uye kusunungura kabhoni dhiabhorosi nekudyidzana necarbonates.Iyo ine simba reducibility uye iri nyore kuve oxidized mucarbon dioxide uye mvura neoxidizing agent.Acid potassium permanganate (KMnO4) mhinduro inogona kuchinjwa uye kuderedzwa kusvika 2-valence manganese ion.

Kushandiswa Kwechigadzirwa

Girazi / fiberglass

Inoshandiswa pakugadzira girazi remaziso, girazi rinodzivirira asidi, girazi re organoborate uye mamwe magirazi epamusoro uye girazi fiber, inogona kuvandudza kupisa kwekupisa uye kujeka kwegirazi, kunatsiridza simba remagetsi, kupfupisa nguva yekunyunguduka.B2O3 inoita basa rehuviri rekuyerera uye kuumbwa kwetiweki mukugadzira girazi negirazi fiber.Semuenzaniso, mukugadzirwa kwegirazi fiber, tembiricha yekunyunguduka inogona kudzikiswa kuti ifambise kudhirowa kwewaya.Kazhinji, B2O3 inogona kuderedza viscosity, kudzora kuwedzera kwemafuta, kudzivirira kupera, kuvandudza kugadzikana kwemakemikari, uye kunatsiridza kuramba kwemechanicha kuvhunduka uye kupisa kwekushisa.Mukugadzirwa kwegirazi uko kunodiwa kuderera kwesodium, boric acid inowanzosanganiswa ne sodium borates (yakadai se borax pentahydrate kana borax anhydrous) kugadzirisa iyo sodium-boron ratio mugirazi.Izvi zvakakosha kune borosilicate girazi nekuti boron oxide inoratidza kunaka kunyungudika mune yakaderera sodium uye yakakwirira aluminium.

Enamel/ceramic

Enamel, indasitiri yeceramic yekugadzira glaze, inogona kuderedza kuwedzera kwekupisa kwe glaze, kuderedza kupisa kwekupisa kwe glaze, kudzivirira kuputika uye kudonha, kunatsiridza kupenya uye kukurumidza kwezvigadzirwa.Kune ceramic uye enamel glazes, boron oxide yakanaka flux uye network inogadzira muviri.Inogona kugadzira girazi (pakupisa kwakadzika), kuvandudza kuchinjika kwe blank glaze, kuderedza viscosity uye kushushikana kwepamusoro, kunatsiridza refractive index, kunatsiridza simba remagetsi, kusimba uye kupfeka kuramba, chinhu chakakosha che lead-isina glaze.Iyo yakakwira boron frit inoibva nekukasira uye inoita kupenya kwakatsetseka nekukasira, izvo zvinoita kuti zvive nemavara.Mune inokurumidza-kupisa glazed tile frit, B2O3 inounzwa se boric acid kuti ive nechokwadi cheyakaderera sodium yemukati inodiwa.

Indasitiri yekuchengetedza hutano

Inoshandiswa mukugadzirwa kwe boric acid mafuta, disinfectant, astringent, preservative uye zvichingodaro.

Flame retardant

Kuwedzera borate kune celluloid zvinhu zvinogona kushandura oxidation maitiro uye kukurudzira kuumbwa kwe "carbonization".Naizvozvo inodzora murazvo.Boric acid, yoga kana kusanganiswa neborax, ine chekuita nekuderedza kupisa kwe celluloid insulation, huni, uye donje matayi mumatiresi.

Metallurgy

Inoshandiswa sekuwedzera uye cosolvent mukugadzirwa kweboron simbi kuita kuti boron simbi ive nekuoma kwakanyanya uye yakanaka rolling ductility.Boric asidhi inogona kudzivirira pamusoro oxidation yesimbi welding, brazing uye casing welding.Iyo zvakare iyo yakasvibiswa ye ferroboron alloy.

Indasitiri yemakemikari

Inoshandiswa mukugadzirwa kwemhando dzakasiyana-siyana, senge sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, potassium borohydride uye zvichingodaro.Mukugadzirwa kwenylon intermediates, boric acid inobata basa rinokonzera mukusanganiswa kwemahydrocarbon uye inogadzira esters kuti iwedzere goho re ethanol, nekudaro ichidzivirira kuwedzera oxidation yemapoka ehydroxyl kugadzira ketoni kana hydroxic acid.Indasitiri yefertilizer yekugadzira tambo dzemakenduru, boron ine fetiraiza.Inoshandiswa seanoongorora kemikari reagent yekugadzirira buffer uye akasiyana midhiya ekuberekesa haploid.
