Oxalic acid yog cov kua qaub tsis muaj zog. Thawj-txiav txim one1 = 5.9 × 10-2 thiab qhov thib ob-xaj one) = 6.4 × 10-5. Nws muaj acid accural. Nws tuaj yeem nruab siab lub hauv paus, discolor qhov ntsuas, thiab tso cov pa roj carbon dioxide los ntawm kev sib cuam tshuam nrog cov pa roj carbonates. Nws muaj kev sib txig sib txig thiab yog qhov yooj yim kom ua oxidized rau hauv cov pa roj carbon dioxide thiab dej los ntawm oxidizing tus neeg sawv cev. Accidanassium permanganate (kmno4) kev daws teeb meem tuaj yeem raug tshem tawm thiab txo qis rau 2-muaj kev sib tw manganese ion.
Evenbright® 'LL tseem muab cov ntsiab lus customized: Cov ntsiab lus / Partenize / Phaj Cov Khoom Siv thiab cov khoom tshwj xeeb uas haum rau koj siv cov xwm txheej, thiab muab cov qauv dawb.

Iav / Fiberglass
Siv rau kev tsim cov iav kho qhov muag, acid des resistant iav thiab lwm yam kev ua kom muaj cua sov, txhim kho cov tshuab muaj zog, ua kom lub sijhawm siv tshuab. B2O3 plays lub ob lub luag haujlwm ntawm flux thiab network tsim hauv kev tsim cov iav thiab cov iav fiber. Piv txwv li, hauv cov iav fiber ntau lawm, qhov kub me me tuaj yeem txo qis los pab txhawb hlau kos duab. Feem ntau, b2o3 tuaj yeem txo viscosity, tiv thaiv kev nthuav dav thermal, thiab txhim kho kev tawm tsam, thiab txhim kho kev tawm tsam kev nyab xeeb thiab cua sov. Hauv cov iav ntau lawm qhov twg cov ntsiab lus tsawg tshaj plaws yog qhov yuav tsum tau, boric acid feem ntau sib xyaw nrog sodium pentahydrate lossis borax anhydrot) los tswj cov khob. Qhov no yog qhov tseem ceeb rau cov iav Borosilicate vim tias Boron oxide qhia zoo solubility nyob rau hauv rooj plaub ntawm cov sodium qis thiab siab aluminium.
Txha hniav / tej hub
Enamel, kev lag luam ceramic rau kev tsim cov ci los ntawm cov ntsej muag kub, kom tiv thaiv qhov tawg thiab Deglazing, txhim kho lub teb thiab nrawm ntawm cov khoom. Rau tej hub thiab enamel glazes, boron oxide yog flux zoo thiab network sib sau lub cev. Nws tuaj yeem tsim cov iav (ntawm qhov qis qis), txhim kho qhov hloov tau zoo thiab coj cov tshuab muaj zog, nws yog ib qho tseem ceeb ntawm txhuas-dawb glaze. Lub Boron high fruit rote rotens sai thiab ua ib lub ntsej muag du sai sai, uas yog conducive rau xim. Nyob rau hauv qhov nrawm-disced vuas luaj frit, b2o3 tau qhia raws li boric acid kom ntseeg tau cov ntsiab lus sodium tsawg.
Kev Saib Xyuas Kev Noj Qab Haus Huv
Siv nyob rau hauv kev tsim cov khoom lag luam boric acid pleev, cov tshuaj tua kab mob, astringent, khaws cia thiab lwm yam.
Nplaim taws retardant
Ntxiv borate rau celluloid cov khoom tuaj yeem hloov nws cov tshuaj tiv thaiv oxidation thiab txhawb kev tsim ntawm "carbonancation". Nws yog vim li no nplaim retardant. Boric acid, nyob ib leeg lossis sib xyaw ua ke nrog borax, muaj cov nyhuv tshwj xeeb rau txo cov nplaim hluav taws xob ntawm cov log tsheb hauv av.
Metallurgy
Nws yog siv los ua tus ntxiv thiab cov cosvent hauv kev tsim cov hlau los ua kom lub boron steel muaj lub hardness thiab zoo dov. Boric acid tuaj yeem tiv thaiv cov npoo oxidation ntawm hlau vuam, brazing thiab casing vuam. Nws tseem yog cov khoom siv raw ntawm ferroboron alloy.
Tshuaj Kev Lag Luam
Siv nyob rau hauv zus tau tej ntau yam ntawm ntau cov laj kab hauv qab, ammonium hydrogen borate, cadmium borohydride thiab li ntawd. Hauv cov nylon intermediates, boric acid ua rau oxidation ntawm hydroxyl pawg los tsim cov khoom siv kertones lossis hydroxic acids. Kev lag luam chiv rau kev tsim cov tswm ciab Wicks, Boron muaj fertilizer. Nws yog siv los ua kev tshuaj ntsuam tshuaj reagent rau kev npaj tsis thiab ntau yam media rau haploid yug.
