Cov Khoom Siv Cov Lus Qhia
Kev siv oxalic acid
1.raws li ib tug bleaching neeg sawv cev
Oxalic acid feem ntau yog siv los txo tus neeg sawv cev thiab tshuaj dawb, siv hauv kev tsim cov tshuaj xws li tshuaj tua kab mob thiab borneol, ua cov kuab tshuaj rau kev rho tawm ntawm cov hlau tsis tshua muaj, ua cov tshuaj tua kab mob, thiab ua tus neeg sawv cev tanning.
Oxalic acid kuj tseem siv rau hauv kev tsim cov cobalt-molybdenum-aluminium catalysts, ntxuav cov hlau thiab marble, thiab bleaching ntawm textiles.
Nws yog siv rau hlau nto tu thiab kev kho mob, tsis tshua muaj lub ntiaj teb lub ntsiab extraction, textile printing thiab dyeing, tawv ua, catalyst npaj, thiab lwm yam.
2. Raws li tus neeg sawv cev txo qis
Hauv kev lag luam organic synthesis, nws yog siv los tsim cov khoom siv tshuaj xws li hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, thiab gallic acid.
Kev lag luam yas yog siv rau hauv kev tsim cov polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer nplooj, thiab lwm yam.
Kev lag luam dyeing yog siv los tsim cov ntsev-raws li magenta ntsuab, thiab lwm yam.
Hauv kev lag luam luam ntawv thiab dyeing, nws tuaj yeem hloov acetic acid thiab siv los ua xim tsim kev pab thiab tshuaj dawb rau cov xim xim.
Kev lag luam kws tshuaj yog siv rau hauv kev tsim cov chlortetracycline, oxytetracycline, tetracycline, streptomycin, thiab ephedrine.
Tsis tas li ntawd, oxalic acid kuj tuaj yeem siv los ua ke ntau yam khoom xws li oxalate, oxalate thiab oxalamide, ntawm cov khoom siv diethyl oxalate, sodium oxalate thiab calcium oxalate yog cov khoom tsim tau tshaj plaws.
3. Raws li ib tug mordant
Antimony oxalate tuaj yeem siv los ua mordant, thiab ferric ammonium oxalate yog tus neeg sawv cev rau kev luam ntawv.
4. Kev tshem tawm xeb muaj nuj nqi
Oxalic acid tuaj yeem siv los tshem tawm cov xeb: noj qee cov oxalic acid, ua cov tshuaj nrog dej sov, siv rau ntawm cov xeb thiab so nws.Tom qab ntawd txhuam nrog metallographic sandpaper thiab thaum kawg tshuaj tsuag xim.
(Ceeb toom: Ceev faj thaum siv, oxalic acid yog corrosive heev rau stainless hlau, oxalic acid nrog siab concentration kuj yog ib qho yooj yim rau corrode tes. Thiab cov kua qaub oxalate generated yog heev soluble, tab sis muaj ib co degree ntawm toxicity. Tsis txhob noj nws. Thaum siv . Tom qab daim tawv nqaij los rau hauv kev sib cuag nrog oxalic acid, nws yuav tsum tau ntxuav nrog dej raws sij hawm.)
