Boric Acid

Kufotokozera mwachidule:

Ndi ufa wa crystalline woyera, womveka bwino komanso wopanda fungo.Gwero lake la acidic sikupereka ma protoni okha.Chifukwa boron ndi atomu yoperewera ma elekitironi, imatha kuwonjezera ma hydroxide ma ion a mamolekyu amadzi ndikutulutsa ma protoni.Pogwiritsa ntchito zinthu zomwe zilibe ma elekitironi, mankhwala a polyhydroxyl (monga glycerol ndi glycerol, ndi zina zotero) amawonjezeredwa kuti apange maofesi okhazikika kuti alimbikitse acidity yawo.

Oxalic acid ndi asidi ofooka.Yoyamba ya ionization nthawi zonse Ka1 = 5.9 × 10-2 ndi yachiwiri kuti ionization nthawi zonse Ka2 = 6.4 × 10-5.Ali ndi acidity yofanana.Itha kusokoneza maziko, kutulutsa chizindikirocho, ndikutulutsa mpweya woipa polumikizana ndi ma carbonates.Imakhala ndi reducibility yamphamvu ndipo ndiyosavuta kuyiyika mu carbon dioxide ndi madzi pogwiritsa ntchito oxidizing.Acid potaziyamu permanganate (KMnO4) yankho limatha kusinthidwa kukhala 2-valence manganese ion.

Kugwiritsa Ntchito Mankhwala

Galasi / fiberglass

Ntchito kupanga galasi kuwala, magalasi asidi zosagwira galasi, organoborate galasi ndi zina zapamwamba galasi ndi galasi CHIKWANGWANI, akhoza kusintha kutentha kukana ndi mandala galasi, kusintha mphamvu mawotchi, kufupikitsa nthawi kusungunuka.B2O3 imagwira ntchito ziwiri pakupanga magalasi ndi magalasi.Mwachitsanzo, popanga ulusi wa magalasi, kutentha kosungunuka kumatha kutsitsidwa kuti zithandizire kujambula waya.Nthawi zambiri, B2O3 imatha kuchepetsa mamasukidwe akayendedwe, kuwongolera kukula kwamafuta, kuteteza kufalikira, kuwongolera kukhazikika kwamankhwala, komanso kukana kugwedezeka kwamakina ndi kugwedezeka kwamafuta.Pakupanga magalasi komwe kumakhala ndi sodium yocheperako, boric acid nthawi zambiri imasakanizidwa ndi sodium borates (monga borax pentahydrate kapena borax anhydrous) kuti azitha kuyang'anira kuchuluka kwa sodium-boron mu galasi.Izi ndizofunikira pagalasi la borosilicate chifukwa boron oxide imawonetsa kusungunuka kwabwino pakakhala sodium yochepa komanso aluminiyamu yayikulu.

Enamel / ceramic

Enamel, makampani a ceramic popanga glaze, amatha kuchepetsa kufalikira kwa glaze, kuchepetsa kutentha kwa glaze, kuti ateteze kusweka ndi kuphulika, kusintha kuwala ndi kufulumira kwa zinthu.Kwa ceramic ndi enamel glazes, boron oxide ndi yabwino kusinthasintha komanso kupanga maukonde thupi.Iwo akhoza kupanga galasi (pa kutentha otsika), kusintha kusinthika kwa glaze akusowekapo, kuchepetsa mamasukidwe akayendedwe ndi kukangana padziko, kusintha refractive index, kusintha makina mphamvu, durability ndi kuvala kukana, ndi mbali yofunika ya kutsogolera wopanda glaze.Boron frit yapamwamba imacha mwachangu ndipo imapanga glaze yosalala mwachangu, yomwe imathandizira kukongoletsa.Mu frit yonyezimira yoyaka mwachangu, B2O3 imayambitsidwa ngati boric acid kuti iwonetsetse kufunikira kwa sodium.

Makampani azaumoyo

Amagwiritsidwa ntchito popanga mafuta a boric acid, mankhwala ophera tizilombo, astringent, preservative ndi zina zotero.

Moto retardant

Kuonjezera borate ku zinthu za celluloid kumatha kusintha makutidwe ndi okosijeni ndikulimbikitsa mapangidwe a "carbonization".Choncho ndi retardant lawi.Asidi wa boric, wokha kapena wophatikizidwa ndi borax, amakhudza kwambiri kuchepetsa kuyaka kwa ma celluloid insulation, matabwa, ndi matayala a thonje m'matilesi.

Metallurgy

Amagwiritsidwa ntchito ngati chowonjezera komanso cosolvent popanga chitsulo cha boron kuti chitsulo cha boron chikhale cholimba kwambiri komanso kugudubuza kwabwino.Boric asidi angalepheretse makutidwe ndi okosijeni pamwamba kuwotcherera zitsulo, brazing ndi casing kuwotcherera.Ndiwonso zopangira za ferroboron alloy.

Makampani opanga mankhwala

Amagwiritsidwa ntchito popanga ma borates osiyanasiyana, monga sodium borohydride, ammonium hydrogen borate, cadmium borotungstate, borohydride potaziyamu ndi zina zotero.Pakupanga nayiloni intermediates, asidi boric amatenga gawo lothandizira mu makutidwe ndi okosijeni wa ma hydrocarbons ndipo amapanga esters kuti awonjezere zokolola za ethanol, potero kupewa makutidwe ndi okosijeni amagulu a hydroxyl kupanga ma ketoni kapena ma hydroxic acid.Makampani a feteleza opangira zingwe za makandulo, boron okhala ndi feteleza.Imagwiritsidwa ntchito ngati chowunikira chamankhwala pokonzekera zotchingira ndi media zosiyanasiyana zoswana haploid.
