KHOOM NTAUB NTAWV

Oxalic acid yog ib qho tsis muaj zog acid.Thawj qhov kev txiav txim ionization tas li Ka1 = 5.9 × 10-2 thiab qhov thib ob-kev txiav txim ionization tas li Ka2 = 6.4 × 10-5.Nws muaj acid commonness.Nws tuaj yeem cuam tshuam lub hauv paus, discolor qhov taw qhia, thiab tso cov pa roj carbon dioxide los ntawm kev cuam tshuam nrog carbonates.Reacts nrog oxidizing agents thiab yog yooj yim oxidized rau carbon dioxide thiab dej.Cov kua qaub potassium permanganate (KMnO4) tuaj yeem hloov xim thiab txo mus rau 2-valence manganese ion.Thaum 189.5 ℃ los yog nyob rau hauv lub xub ntiag ntawm concentrated sulfuric acid, nws yuav decompose rau carbon dioxide, carbon monoxide thiab dej.H2C2O4=CO2↑+CO↑+H2O.

KHOOM SIV

QIB INDUSTRIAL

Synthetic catalyst

Raws li ib qho catalyst rau phenolic resin synthesis, cov tshuaj tiv thaiv catalytic yog me me, cov txheej txheem kuj ruaj khov, thiab lub sijhawm ntev tshaj plaws.Oxalate acetone tov tuaj yeem ua rau cov tshuaj tua kab mob ntawm epoxy resin thiab txo lub sijhawm kho.Nws kuj yog siv los ua pH regulator rau cov synthesis ntawm urea-formaldehyde resin thiab melamine formaldehyde resin.Nws tseem tuaj yeem muab ntxiv rau cov dej-soluble polyvinyl formaldehyde nplaum los txhim kho qhov ziab nrawm thiab kev sib khi lub zog.Nws kuj yog siv los ua tus neeg sawv cev kho ntawm urea-formaldehyde resin thiab hlau ion chelating tus neeg sawv cev.Nws tuaj yeem siv tau los ua kom nrawm rau kev npaj cov hmoov txhuv nplej siab nrog KMnO4 oxidizer kom nrawm oxidation tus nqi thiab txo lub sij hawm cov tshuaj tiv thaiv.

Tus neeg saib xyuas tu

Oxalic acid tuaj yeem siv los ua tus neeg saib xyuas, feem ntau yog vim nws muaj peev xwm chelate (khi) ntau cov hlau ions thiab cov zaub mov, suav nrog calcium, magnesium, aluminium, thiab lwm yam.oxalic acidtshwj xeeb tshaj yog tsim rau tshem tawm cov txiv qaub thiab limescale.

Printing & dyeing

Kev lag luam luam ntawv thiab dyeing tuaj yeem hloov acetic acid rau kev tsim cov hauv paus ntsuab thiab lwm yam.Siv los ua cov xim pab xim thiab tshuaj dawb rau cov xim dyes.Nws tuaj yeem ua ke nrog qee yam tshuaj los tsim cov dyes, thiab tseem tuaj yeem siv los ua tus stabilizer rau dyes, yog li ncua lub neej ntawm dyes.

Kev lag luam yas

Plastics kev lag luam rau kev tsim cov polyvinyl chloride, amino plastics, urea-formaldehyde plastics, xim chips thiab lwm yam.

Kev lag luam photovoltaic

Oxalic acid kuj tseem siv hauv kev lag luam photovoltaic.Oxalic acid tuaj yeem siv los ua silicon wafers rau cov hnub ci vaj huam sib luag, pab txo qhov tsis xws luag ntawm cov wafers.

Xuab zeb ntxuav kev lag luam

Ua ke nrog hydrochloric acid thiab hydrofluoric acid, nws tuaj yeem ua rau cov kua qaub ntxuav ntawm quartz xuab zeb.

Tawv ua

Oxalic acid tuaj yeem siv los ua tus neeg sawv cev tanning hauv cov txheej txheem tawv.Nws muaj peev xwm nkag mus rau hauv cov tawv fibers, ua rau lawv ruaj khov thiab tiv thaiv rot thiab hardening.

Kev tshem tawm xeb

tuaj yeem ncaj qha tshem tawm cov xeb ntawm npua hlau, stainless hlau thiab lwm yam hlau.
