1.I-Boric acid iyinhlanganisela yekristalu eyakhiwe ngokuncibilikisa i-boron trioxide emanzini.Kuyi-asidi ye-inorganic, ikakhulukazi ehlanganisa i-tetraboric acid H2B4O7 (eyaziwa nangokuthi i-pyroboric acid), i-metaboric acid (HBO2) n ne-orthoboric acid H3BO3 (eyaziwa nangokuthi i-orthoboric acid).Phakathi kwabo, i-orthoboric acid inokuqukethwe kwamanzi okuzinzile kakhulu.I-Orthoboric acid, ebizwa nangokuthi i-boric acid ngamafuphi, iyikristalu emhlophe eyimpuphu noma i-triaxial chemicalbook scaly junction crystal ene-luster.Inokunambitheka okubabayo okuncane.Izwakala inamafutha uma ithinta isikhumba.Ayinaphunga futhi iyancibilika emanzini, i-ethanol, i-glycerin, i-ethers ne-essence.Isixazululo se-aqueous sine-asidi ebuthakathaka.I-Orthoboric acid iphelelwa amanzi kancane kancane ibe yi-metaboric acid uma ishisiswe ibe ngu-70-100 ℃, i-pyroboric acid uma ishisiswe ibe ngu-150 ℃ -160 ℃, kanye ne-boric anhydride (B2O3) uma ishisiswe kufika ku-300 ℃.
2.Isixazululo esinamanzi sine-asidi ebuthakathaka, okuyi-asidi ye-Lewis evamile.Lapho kukhona i-hydrochloric acid, i-citric acid noma i-tartaric acid, ingakhuthaza ukuncibilika emanzini.Ngakho-ke, ingahlanzwa nge-recrystallization.
3. Ngokuvamile, i-boric acid ayinabo ubuthi.Umthamo obulalayo wabantu abadala ungamagremu ayi-15 kuya ku-20 ngekhilogremu ngayinye yesisindo somzimba, kanti owezingane ungama-3 ~ 6 amagremu ngekhilogremu ngayinye yesisindo somzimba.Inani elikhulu lokumuncwa lingase liholele kushevu oyingozi.Izimpawu zokuqala ukuhlanza, isifo sohudo, ukuqubuka kwesikhumba, futhi isimiso sezinzwa esimaphakathi siyajatshuliswa kuqala bese siyavinjelwa.Ukwehluleka okukhulu kokujikeleza kwegazi noma ukushaqeka, ngokuvamile ezinsukwini ezi-3 kuya kwezi-5 zokufa.Ukusetshenziswa kaningi kwemithamo emincane kuzonqwabelana emzimbeni, okuholela ekubeni nobuthi obungapheli, i-anorexia, ukukhathala, ukusangana, i-dermatitis, impandla, kanye nokuphazamiseka kokuya esikhathini.
Isicelo
I-1.I-boric acid isetshenziswa kakhulu emikhiqizweni yengilazi, ikakhulukazi emikhiqizweni yengilazi ekwazi ukumelana nokushisa namakhemikhali.I-Boron carbide eyenziwe nge-boric acid ingasetshenziswa njenge-abrasive.Ngaphezu kwalokho, ingasetshenziswa koqweqwe lwawo, umuthi we-ceramic glaze, izingulube ze-inorganic, umanyolo kanye nokukhiqizwa kwe-metallurgical.
I-2.Isetshenziswa kabanzi embonini yengilazi (ingilazi ye-optical, ingilazi engamelana ne-asidi, ingilazi engangeni ekushiseni, i-glass fiber yezinto zokuvikela ukushisa), engathuthukisa ukumelana nokushisa nokucaca kwemikhiqizo yengilazi, ithuthukise amandla emishini, futhi ifinyeze isikhathi sokuncibilika.Embonini ye-koqweqwe lwawo kanye ne-ceramic, isetshenziselwa ukuthuthukisa ukucwebezela nokushesha kwemikhiqizo yoqweqwe lwawo, futhi ingenye yezithako zomuthi we-glaze nezingulube.Njengezithasiselo kanye ne-cosolvent embonini ye-metallurgical, insimbi ye-boron ikakhulukazi inobulukhuni obuphezulu kanye ne-ductility enhle yokugoqa, engangena esikhundleni sensimbi ye-nickel.I-boric acid inokumelana nokugqwala futhi ingasetshenziswa njengesilondolozi samakhemikhali eNcwadini, njengokuvimbela ukugqwala kwezinkuni.Isetshenziswa ekushiseleni insimbi, isikhumba, ukuthwebula izithombe nezinye izimboni, kanye nokukhiqizwa kodayi, izindwangu ezingashisi futhi ezingashi, amatshe ayigugu okwenziwa, ama-capacitor nezimonyo.
3. Ingasetshenziswa futhi njengesibulala-zinambuzane kanye ne-catalyst.I-Boron equkethe umanyolo we-trace element kwezolimo iyasebenza ezitshalweni eziningi futhi ingathuthukisa ikhwalithi yezitshalo kanye nesivuno.I-Boric acid nayo ingenye yezinto eziyisisekelo zokwenziwa kokukhiqizwa kwamanye ama-boride.Izinhlanganisela ze-boron ezikhiqizwa yi-boric acid zisetshenziswa kakhulu ekuvikelweni kwezwe nakweminye iminyango yezimboni nezikhungo zocwaningo lwesayensi.
