CAS: 10043-35-3
1. Boric acid ndi crystalline pawiri wopangidwa ndi kusungunula boron trioxide m'madzi.Ndi asidi wachilengedwe, makamaka kuphatikiza tetraboric acid H2B4O7 (yomwe imadziwikanso kuti pyroboric acid), metaboric acid (HBO2) n ndi orthoboric acid H3BO3 (yomwe imadziwikanso kuti orthoboric acid).Pakati pawo, orthoboric acid imakhala ndi madzi okhazikika kwambiri.Orthoboric acid, yomwe imatchedwanso boric acid mwachidule, ndi white powdery crystal kapena triaxial chemicalbook scaly junction crystal yokhala ndi luster.Imakhala ndi kukoma pang'ono.Imamva mafuta pokhudzana ndi khungu.Ndiwopanda fungo ndipo amasungunuka m'madzi, ethanol, glycerin, ethers ndi essence.Njira yamadzimadzi ndi yofooka acidic.Orthoboric acid imachepetsedwa pang'onopang'ono mpaka metaboric acid ikatenthedwa mpaka 70-100 ℃, pyroboric acid ikatenthedwa mpaka 150 ℃ -160 ℃, ndi boric anhydride (B2O3) ikatenthedwa mpaka 300 ℃.
2. Njira yamadzimadzi imakhala yochepa kwambiri, yomwe ndi asidi wa Lewis.Pamaso pa hydrochloric acid, citric acid kapena tartaric acid, imatha kulimbikitsa kusungunuka m'madzi.Choncho, akhoza kuyeretsedwa ndi recrystallization.
3. Nthawi zambiri, asidi wa boric siwowopsa.Mlingo wakupha wa akuluakulu ndi pafupifupi 15 ~ 20 magalamu pa kilogalamu ya kulemera kwa thupi, pamene wa ana ndi 3 ~ 6 magalamu pa kilogalamu ya kulemera kwa thupi.Kuchuluka kwa mayamwidwe kungayambitse pachimake poyizoni.Zizindikiro zoyamba ndi kusanza, kutsekula m'mimba, zotupa pakhungu, ndipo dongosolo lapakati la minyewa limakondwera poyamba ndiyeno limaletsedwa.Kulephera kwakukulu kwa magazi kapena kugwedezeka, kawirikawiri m'masiku 3 mpaka 5 a imfa.Kumwa mobwerezabwereza Mlingo waung'ono kumachulukana m'thupi, zomwe zimapangitsa kuti munthu azidwala matenda a anorexia, kutopa, misala, dermatitis, dazi, ndi matenda a msambo.
Kugwiritsa ntchito
1.Boric acid imagwiritsidwa ntchito makamaka muzinthu zamagalasi, makamaka muzinthu zamagalasi zosagwirizana ndi kutentha komanso mankhwala.Boron carbide yopangidwa ndi boric acid imatha kugwiritsidwa ntchito ngati abrasive.Komanso, angagwiritsidwe ntchito enamel, ceramic glaze mankhwala, inorganic inorganic, feteleza ndi kupanga zitsulo.
2.Imagwiritsidwa ntchito kwambiri mumakampani agalasi (galasi lagalasi, galasi losagwira asidi, galasi losatentha, galasi lopanda kutentha, ulusi wagalasi wa zida zotsekera), zomwe zimatha kusintha kukana kutentha ndi kuwonekera kwa zinthu zamagalasi, kukulitsa mphamvu zamakina, ndikufupikitsa nthawi yosungunuka.M'makampani a enamel ndi ceramic, amagwiritsidwa ntchito kupititsa patsogolo kung'anima ndi kufulumira kwa zinthu za enamel, komanso ndi chimodzi mwazosakaniza za mankhwala a glaze ndi inki.Monga zowonjezera ndi cosolvent mumakampani opanga zitsulo, chitsulo cha boron makamaka chimakhala ndi kuuma kwambiri komanso kugudubuza kwabwino, komwe kungalowe m'malo mwachitsulo cha faifi tambala.Boric acid ali ndi kukana dzimbiri ndipo angagwiritsidwe ntchito ngati mankhwala Book preservative, monga nkhuni dzimbiri kupewa.Amagwiritsidwa ntchito powotcherera zitsulo, zikopa, kujambula zithunzi ndi mafakitale ena, komanso kupanga utoto, nsalu zosagwira kutentha ndi moto, miyala yamtengo wapatali, ma capacitors ndi zodzoladzola.
3. Itha kugwiritsidwanso ntchito ngati mankhwala ophera tizilombo komanso chothandizira.Boron yokhala ndi feteleza wa trace element paulimi ndi othandiza pa mbewu zambiri ndipo imatha kupititsa patsogolo mbewu komanso zokolola.Boric acid ndi chimodzi mwazinthu zopangira zopangira ma borides ena.Mankhwala a boron opangidwa ndi boric acid amagwiritsidwa ntchito kwambiri poteteza dziko ndi madipatimenti ena ogulitsa mafakitale ndi mabungwe ofufuza zasayansi.
