Boric acid

Kufotokozera kwaifupi:

Ndi ufa woyera wa kristoli, wosalala pang'ono komanso wopanda fungo. Gwero lake la acidic silikupereka ma propston pawokha. Chifukwa Boron ndi atomu yosayenerera ya electron, imatha kuwonjezera ma mayoke a hydroxide a mamolekyulu amadzi ndikutulutsa ma proton. Kugwiritsa ntchito katundu wa electron-penti yopanda kanthu, ma polyhydroxyl (monga glycerol ndi glycerol, etc.) amawonjezeredwa kuti apange ma codes okhazikika kuti alimbikitse acidity yawo.

Oxalic acid ndi ofooka acid. Woyambitsa May-Order Loven Ka1 = 5.9 × 10-2 ndi yachiwiri - inoit-dongosolo lokhalapo KA2 = 6.4 × 10-5. Ili ndi wambani. Itha kusokoneza maziko, discolor chizindikiritso, ndikumasula mpweya woipa malinga ndi mgwirizano wa carbemin. Imakhala ndi kuthekera kwamphamvu ndipo ndikosavuta kukhala oxidizere mu kaboni dayokisi ndi madzi mwa wogula. Acid potaziyamu permanganate (kmno4) yankho limatha kusungunuka ndikuchepetsedwa mpaka 2-valencese ion.

Galasi / fiberglass

Kugwiritsa ntchito popanga galasi lokon, magalasi osagonjetsedwa acid, galasi lina lokhazikika ndi galasi lina lagalasi, limatha kusintha mphamvu yagalasi, kufupikitsa nthawi yopanga. B2o3 imatenga gawo lawiri la flux ndi matchulidwe a network popanga galasi ndi galasi. Mwachitsanzo. Mwambiri, B2O3 imatha kuchepetsa mamasukidwe, sinthani kuwonjezeka kwa mafuta, kupewa kufooka, kukonza manyowa, ndikusintha kusokonezeka kwamakina ndi kugwedezeka. Mu glass kupanga pomwe zotsika kwambiri za sodium ndizofunikira, boric acid nthawi zambiri zimasakanizidwa ndi sodium Izi ndizofunikira pagalasi ya borosiltialillate chifukwa Boron oxide akuwonetsa zosungunulira bwino pakakhala sodium yotsika komanso yamphamvu kwambiri.

Enamel / ceramic

Artmel, malonda ogulitsa za ceral pakupanga glaze, amatha kuchepetsa kukula kwa mafuta, kuchepetsa kutentha kwa glaze, kuti muchepetse kusweka ndi kutsuka, kusintha kwa zinthu zina. Kwa ceramic ndi enamel grazes, boron oxide ndi thupi labwino komanso lopanga ma network. Itha kupanga galasi (pamatenthedwe otsika), sinthani kusintha kwa zinthu zopanda kanthu, kuchepetsa ubweya wokhazikika, kusintha mphamvu yopanga, kufooka, ndi gawo lofunikira kwambiri. Boron Wamtunda wa Boron amaba mwachangu ndipo amapanga udzu wosalala msanga, womwe umatha kukongoletsa utoto. Mu katemera wowomba wachangu, B2o3 amayambitsidwa ngati boric acid kuti awonetsetse zotsala zotsika kwambiri sodium.

Boric acid, yokha kapena kuphatikiza ndi borax, imakhala ndi mwayi wapadera kuchepetsa kudzikuza kwa celluloid, nkhuni, ndi matayala a thonje mu matiresi.

Makampani Amakampani

Kugwiritsa ntchito popanga ma borates osiyanasiyana, monga sodium Borohydride, ammonium hydrogen borophstate, potaziyamu a Borohydride ndi zina zambiri. Pakupanga kwa nayiloni pakati, Boric acid amagwira ntchito yothandizira ma hydrocarbons ndikupanga zokolola za ethanol, poteteza makilosi a hydroxyl. Makampani feteleza pakupanga kandulo, boron amakhala ndi feteleza. Amagwiritsidwa ntchito ngati mankhwala opanga mankhwala pokonzekera buffer ndi mitundu yosiyanasiyana ya kuswana kwa Happloid.
