Product tsanangudzo
MF: BH3O3
MW: 61.83
CAS: 10043-35-3
1. Boric asidhi musanganiswa wecrystalline unoumbwa nekunyungudutsa boron trioxide mumvura.Iyo inorganic acid, kunyanya kusanganisira tetraboric acid H2B4O7 (inozivikanwawo se pyroboric acid), metaboric acid (HBO2) n uye orthoboric acid H3BO3 (inozivikanwawo se orthoboric acid).Pakati pavo, orthoboric acid ine yakanyanya kugadzikana yemvura.Orthoboric acid, inonziwo boric acid kwenguva pfupi, ichena upfu crystal kana triaxial chemicalbook scaly junction crystal ine luster.Iine kakunaka kanovava.Inonzwa kukora pakubata neganda.Haina hwema uye inonyungudika mumvura, ethanol, glycerin, ethers uye essence.Mushonga wemvura une acidic zvishoma.Orthoboric acid inopera zvishoma nezvishoma kuita metaboric acid kana ichipisa kusvika 70-100 ℃, pyroboric acid kana ichipisa kusvika 150 ℃ -160 ℃, uye boric anhydride (B2O3) kana ichipisa kusvika 300 ℃.
2. Mushonga wemvura hauna kusimba acidic, inova yakajairwa Lewis acid.Muhupo hwehydrochloric acid, citric acid kana tartaric acid, inogona kukurudzira kunyungudika mumvura.Nokudaro, inogona kucheneswa nekugadzirisa zvakare.
3. Kazhinji, boric acid haina chepfu.Mushonga unouraya wevakuru ungangoita 15 ~ 20 magiramu pakirogiramu yehuremu hwemuviri, nepo yevana iri 3 ~ 6 magiramu pakirogiramu yehuremu hwemuviri.Kunyura kwakawanda kunogona kutungamirira kune acute chepfu.Zviratidzo zvekutanga kurutsa, manyoka, kuputika kweganda, uye central nerve system inotanga kufara uye inodziviswa.Kutadza kutenderera kweropa kwakanyanya kana kuvhunduka, kazhinji mumazuva matatu kusvika mashanu erufu.Kudzokororwa kunwiwa kwedosi diki kunoungana mumuviri, zvichizotungamira muchetura usingaperi, anorexia, kuneta, kupenga, dermatitis, mhanza, uye kusagadzikana kwekuenda kumwedzi.
Application
1.Boric acid inonyanya kushandiswa muzvigadzirwa zvegirazi, kunyanya mukupisa-kupisa uye makemikari asingagadziri magirazi zvigadzirwa.Boron carbide inogadzirwa ne boric acid inogona kushandiswa seabrasive.Mukuwedzera, inogona kushandiswa mune enamel, ceramic glaze mushonga, inorganic pigments, fetiraiza uye metallurgical kugadzirwa.
2.Inoshandiswa zvakanyanya muindasitiri yegirazi (girazi remaziso, girazi rinodzivirira asidhi, girazi rinodzivirira kupisa, girazi fiber yezvinhu zvinodzivirira), izvo zvinogona kuvandudza kupisa kwekupisa uye kujeka kwezvigadzirwa zvegirazi, kuvandudza simba remagetsi, uye kupfupisa nguva yekunyungudika.Muindasitiri yeenamel neceramic, inoshandiswa kusimudzira kupenya uye kukurumidza kwezvigadzirwa zveenamel, uye iri zvakare chimwe chezviyo zvemishonga yeglaze uye pigments.Sezvinowedzera uye cosolvent muindasitiri yesimbi, boron simbi kunyanya ine kuomarara kwakanyanya uye yakanaka rolling ductility, inogona kutsiva nickel simbi.Boric acid ine corrosion resistance uye inogona kushandiswa sekemikari Book preservative, yakadai sehuni yekudzivirira kuora.Inoshandiswa musimbi welding, dehwe, kutora mifananidzo uye mamwe maindasitiri, pamwe nekugadzirwa kwedhayi, machira asingasviki uye asingadziviriri moto, matombo anokosha ekugadzira, capacitors uye cosmetics.
3. Inogonawo kushandiswa semushonga wezvipembenene uye catalyst.Boron ine trace element fetereza mukurima inoshanda kune zvirimwa zvakawanda uye inogona kuvandudza kunaka kwechirimwa uye goho.Boric acid zvakare imwe yezvakakosha zviwanikwa zvekugadzira mamwe mabhoride.Iyo boron compounds inogadzirwa ne boric acid inoshandiswa zvakanyanya mukudzivirira kwenyika uye mamwe madhipatimendi eindasitiri uye masangano ekutsvagisa sainzi.
