Qhov sib txawv tseem ceeb ntawm borax thiab boric hmoov yog tias borax yog cov ntxhia tshwm sim, thaum boric hmoov yog tsim los ntawm borax.
Borax thiab boric hmoov yog cov tshuaj tsis muaj tshuaj lom neeg ntawm cov tshuaj boron. Borax muaj sodium, boron, hydrogen thiab oxygen atoms thaum boric hmoov muaj boron, hydrogen thiab oxygen atoms.
Borax yog dab tsi?
Borax yog lub npe nrov rau cov ntaub ntawv tsis muaj dej lossis dej ntawm sodium borate. Peb tuaj yeem soj ntsuam qhov sib xyaw no ua ntsev ntawm boric acid. Cov tshuaj formula ntawm no compound yog Na2B4O7·10H 2O. Cov mis no muaj kaum dej molecules txuam nrog sodium borate molecule vim lub npe borax feem ntau yog siv rau decahydrate daim ntawv ntawm sodium borate. Cov khoom no zoo li cov khoom dawb. Cov molar mass ntawm no compound yog 381.38 g / mol. Nws yooj yim hloov mus rau hauv boric acid.
Daim duab 01: Complex
Ntxiv mus, peb tuaj yeem siv qhov sib xyaw no (daim ntawv decahydrate) ua tus qauv tseem ceeb rau kev tsom xam titrimetric. Tias yog vim hais tias cov compound no txaus ruaj khov thiab ntshiab rau lub hom phiaj ntawd. Borax ib txwm tshwm sim hauv cov evaporite tso tawm los ntawm kev rov ua dua ntawm cov pas dej raws caij nyoog.
Muaj ntau ntau yam kev siv borax suav nrog kev siv cov tshuaj no los ua cov khoom xyaw hauv cov khoom ntxhua khaub ncaws thiab tshuaj ntxuav, hauv kev ua cov tshuaj tsis haum, tsim cov complexes nrog ntau yam tshuaj, hauv dej-softening, thiab rau cov tshuaj tua kab mob. extraction ntawm kub nyob rau hauv me me scale kub mining txheej txheem, thiab lwm yam.
Boric Powder yog dab tsi?
boric hmoov yog lo lus siv rau boric acid, uas feem ntau tshwm li cov hmoov dawb dawb. Nws tseem muaj npe hu ua hydrogen borate, boracic acid, thiab raws li orthoboric acid. Nws yog ib qho tsis muaj zog thiab monobasic Lewis acid ntawm cov tshuaj boron. Monobasic txhais tau hais tias cov tshuaj no tuaj yeem tso tawm tsuas yog ib qho proton ib molecule hauv nruab nrab acidic; Txawm li cas los xij, qee qhov ntawm nws tus cwj pwm qhia tias nws tuaj yeem yog tribasic thiab. Cov tshuaj formula ntawm no compound yog H3BO3. Hauv nws daim ntawv ntxhia los ntawm qhov nws tau muab los, boric hmoov yog lub npe hu ua sassolite.
Daim duab 02: Boric Powder
Peb tuaj yeem npaj boric acid los ntawm cov tshuaj tiv thaiv ntawm borax thiab ntxhia acids xws li HCl acid. Nws kuj yog tsim los ntawm cov khoom siv los ntawm cov txheej txheem hydrolysis ntawm boron trihalide thiab diborane. Feem ntau, boric hmoov yog dej-soluble, tshwj xeeb tshaj yog nyob rau hauv boiling dej. Txawm li cas los xij, siab dua 170 degrees Celsius, cov khoom no nyiam lub cev qhuav dej, tsim cov metaboric acid lossis HBO2.
Muaj ntau ntau yam kev siv boric hmoov nrog rau kev tsim cov monofilament fiberglass los yog textile fiberglass, kom txo tau oxidation nto nyob rau hauv cov hniav nyiaj hniav kub kev lag luam, raws li ib tug nyob rau hauv gradient nyob rau hauv cov txheej txheem electroplating, raws li ib tug antiseptic tshuaj, raws li ib tug muaj nyob rau hauv Cov tshuaj tua kab, nyob rau hauv cov nplaim hluav taws, ua cov khoom siv neutron, thiab ua cov khoom ua ntej rau lwm cov tshuaj lom neeg.
Qhov txawv ntawm Borax thiab Boric Powder yog dab tsi?
Borax thiab boric hmoov yog cov tshuaj tsis muaj tshuaj lom neeg ntawm boron tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm borax thiab boric hmoov yog tias borax yog ib qho ntxhia tshwm sim thaum boric hmoov yog tsim los ntawm borax.
Borax yog cov khoom xyaw hauv cov khoom ntxhua khaub ncaws, tshuaj ntxuav, thiab ua cov tshuaj tsis haum. Nws ib co ntawm lwm yam kev siv yog nyob rau hauv kev tsim complexes nrog ntau lwm yam tshuaj, nyob rau hauv dej-softening, thiab rau extraction ntawm kub nyob rau hauv me me scale kub mining txheej txheem. Boric, ntawm qhov tod tes, yog siv rau hauv kev tsim cov monofilament fiberglass los yog textile fiberglass, kom txo tau qhov chaw oxidation nyob rau hauv cov hniav nyiaj hniav kub kev lag luam, raws li ib tug nyob rau hauv gradient nyob rau hauv cov txheej txheem electroplating, raws li ib tug antiseptic tshuaj, raws li ib tug muaj nyob rau hauv cov tshuaj tua kab, nyob rau hauv nplaim taws. retardants, raws li ib tug neutron absorber, thiab raws li ib tug precursor rau lwm cov tshuaj compounds.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm borax thiab boric hmoov.
Summary – Borax vs Boric Powder
Borax thiab boric hmoov yog cov tshuaj tsis muaj tshuaj lom neeg ntawm cov tshuaj boron. Qhov sib txawv tseem ceeb ntawm borax thiab boric hmoov yog tias borax yog ib qho ntxhia tshwm sim, thaum boric hmoov yog tsim los ntawm borax.
