Cov ntawv thov ntawm Oxalic Acid hauv Textile Printing thiab Dyeing
Hauv kev lag luam tshuaj lom neeg, oxalic acid yog siv los tsim pentaerythritol, cobalt oxalate, nickel oxalate, fuchsin yooj yim, cov khoom siv reagent tiav rau kev tshuaj xyuas hlau thiab av, cov tshuaj reagents, thiab lwm yam khoom.
Hauv cov txheej txheem dyeing sai, nws ua haujlwm ua tus neeg sawv cev txhim kho xim thiab ua kom sib npaug.
Nws ua haujlwm ua tus neeg sawv cev dawb rau cov khoom siv straw thiab cov nplej straw (siv cov khoom txo qis oxalic acid) thiab ua tus tshem tawm cov xeb (oxalic acid reacts nrog hlau los tsim cov hlau oxalate uas yaj tau, uas yooj yim ntxuav nrog dej, yog li tshem tawm cov hlau stains ntawm cov ntaub).
Cov ntawv thov ntawm Oxalic Acid hauv Textile Printing thiab Dyeing
(1) Tshem Tawm Cov Xim Xeb Ntawm Cov Ntaub
Thaum hlau raug rau cov pa oxygen thiab cov dej noo hauv huab cua, nws tsim cov tshuaj sib xyaw ua ke hu ua xeb. Txawm hais tias qhov sib xyaw ua ke sib txawv ntawm cov xwm txheej tsim, txhua qhov xeb muaj cov hlau trivalent ions. Cov xim xeb ntawm cov ntaub paj rwb tsim cov qhov tsis zoo tas mus li uas yuav tsum tau tshem tawm, thiab oxalic acid yog ib tus neeg sawv cev zoo rau kev tshem tawm lawv. Lub hauv paus ntsiab lus yog tias oxalic acid reacts nrog trivalent hlau ions (Fe³⁺) los tsim cov tshuaj anionic complex ion, [Fe(C₂O₄)₃]³⁻, uas yooj yim yaj hauv dej. Kev siv ib txwm yog 20 g/L ntawm oxalic acid nrog kwv yees li 30 mL/L ntawm 98% acetic acid.
Lus Cim Tseem Ceeb: Oxalic acid tuaj yeem ua rau cov fiber puas tsuaj. Tom qab kho, cov ntaub paj rwb yuav tsum tau ntxuav kom huv si nrog dej huv kom tshem tawm tag nrho cov oxalic acid seem. Yog tias tsis ntxuav kom huv, cov oxalic acid dilute yuav sib xyaw thaum lub sijhawm ziab, ua rau cov fiber puas tsuaj loj heev thiab tsim cov qhov.
Oxalic acid kuj tseem tuaj yeem tshem tawm cov xeb ntawm cov ntaub nylon, uas yuav ua rau daj.
(2) Tshem Tawm Cov Pa Roj Nitrous Acid Thaum Lub Sijhawm Tsim Nrog Cov Xim Ingrain
Thaum siv txoj kev sodium nitrite rau kev luam ntawv ncaj qha nrog cov xim ingrain nrog rau cov xim naphthol, cov kua qaub nitrous raug tsim thaum lub sijhawm tsim cov kua qaub sulfuric. Qhov no ua rau cov ntsev sodium naphthol AS ntawm daim ntaub tsim cov xim av liab, ua rau cov av dawb tsis sib xws. Txhawm rau tshem tawm cov kua qaub nitrous, qee zaum ntxiv 1-2 g / L ntawm oxalic acid rau hauv cov kua sulfuric acid tsim ua tus neeg sawv cev txo qis (hloov cov kua qaub formic, urea, lossis sulfur). Oxalic acid txo cov kua qaub nitrous rau hauv cov pa nitrogen, tiv thaiv HNO₂ los ntawm kev cuam tshuam nrog AS los tsim cov khoom sib xyaw xim av.
Zibo Anhao Chemical Co., Ltd. xa cov tshuaj Oxalic Acid (Ethanedioic Acid, CAS 144-62-7) zoo uas tsim los rau kev ntseeg siab hauv kev lag luam thiab kev ua haujlwm tas mus li. Peb cov tshuaj oxalic acid muaj nyob rau hauv cov hmoov dawb crystalline lossis cov siv lead ua pob tshab tsis muaj xim, muaj qhov huv ≥99.6%, tsis muaj dej noo, thiab tsis muaj kuab paug ntau, ua kom ntseeg tau tias muaj txiaj ntsig zoo rau txhua daim ntawv thov.
Tsim los rau kev siv tau ntau yam, nws zoo heev rau kev ntxuav cov hlau, zas xim thiab ua kom dawb ntawm cov ntaub, tanning tawv, rho tawm cov khoom tsis tshua muaj, thiab kho cov dej khib nyiab. Nrog cov yam ntxwv txo qis thiab chelating muaj zog, nws tshem tawm cov xeb, nplai, thiab cov xim av thaum txhawb nqa kev ua tshuaj lom neeg kom raug.
Tsim los ntawm kev tswj xyuas zoo nruj thiab tau ntawv pov thawj nrog SGS, BV, thiab FAMI-QS, peb cov oxalic acid ua tau raws li cov qauv kev lag luam thoob ntiaj teb. Peb muab cov ntim khoom yooj ywm - 25kg hnab, 50kg nruas, thiab IBCs loj - nrog kev xa khoom ruaj khov thiab kev xa khoom tshaj lij los txhawb kev koom tes thoob ntiaj teb.Tiv tauj peb rau kev txiav txim ntau lossis cov lus qhia txog kev siv: info@anhaochemical.com
