Kev siv ntau yam ntawm Formic Acid hauv Tawv, Textile, Kev Ua Liaj Ua Teb & Kev Tu Tu

Formic acid (HCOOH) yog cov tsis muaj xim, pungent kua nrog ntau hom kev lag luam, ua tsaug rau nws cov acidity muaj zog, solubility, thiab biodegradability. Nws yog ib qho yooj yim tshaj plaws carboxylic acids, thiab nws cov khoom tshwj xeeb ua rau nws indispensable nyob rau hauv kev lag luam xws li tawv, textile, ua liaj ua teb, thiab industrial tu. Kab lus no tshawb txog ntau yam kev siv ntawm formic acid nyob rau hauv cov haujlwm tseem ceeb no, qhia txog nws lub luag haujlwm hauv kev txhim kho kev ua tau zoo, zoo, thiab kev ruaj khov.

 

Hauv kev lag luam tawv, formic acid yog ib qho tseem ceeb hauv cov txheej txheem tanning. Nws yog siv los kho pH ntawm tawv thaum lub sij hawm tanning, pab tshem tawm cov plaub hau thiab rog los ntawm raw hides thiab npaj lawv rau kev ua ntxiv. Formic acid kuj ua raws li kev kho tus neeg sawv cev rau dyes, kom ntseeg tau tias cov xim ci, zoo ib yam, thiab ntev - kav ntev. Tsis tas li ntawd, nws pab ua kom tawv nqaij, txhim kho nws yooj yim thiab kev ntxhib los mos, ua rau nws haum rau cov khoom xws li khau, hnab, thiab rooj tog zaum. Nws biodegradability ua rau nws muaj ntau dua eco- lwm txoj hauv kev zoo rau cov hluavtaws hluavtaws uas ib txwm siv hauv tawv tanning.

 

Kev lag luam textile cia siab rau formic acid rau ntau yam txheej txheem tseem ceeb, suav nrog dyeing, luam ntawv, thiab ua tiav. Nws yog siv los kho cov pH ntawm cov dye da dej, kom ntseeg tau tias qhov zoo tshaj plaws dye absorption thiab xim ceev ceev. Formic acid kuj tseem pab tshem tawm cov xim ntau dhau ntawm cov ntaub ntawv, tiv thaiv los ntshav thiab ua kom cov xim tsis sib xws. Hauv textile printing, nws ua raws li cov thickener thiab stabilizer, txhim kho qhov zoo ntawm cov ntawv luam tawm. Tsis tas li ntawd, nws yog siv nyob rau hauv cov txheej txheem xov kom soften fabrics thiab txhim kho lawv wrinkle kuj. Nws solubility nyob rau hauv ob qho tib si dej thiab cov kuab tshuaj organic ua rau nws muaj ntau yam kev siv nrog ntau yam ntawm textiles, xws li paj rwb, ntaub plaub, thiab hluavtaws fabrics.

 

Hauv kev ua liaj ua teb, formic acid yog siv los ua silage preservative thiab pub acidifier. Silage yog cov khoom noj tseem ceeb rau cov tsiaj txhu, thiab formic acid pab tiv thaiv kev lwj los ntawm inhibiting kev loj hlob ntawm pwm thiab kab mob. Nws kuj tseem txhim kho cov khoom noj muaj txiaj ntsig ntawm silage los ntawm kev khaws cov proteins thiab txo cov zaub mov poob. Raws li pub acidifier, formic acid pab txo qis pH ntawm cov tsiaj plab, txhim kho kev zom zaub mov thiab kev nqus cov as-ham, thiab txo qis kev pheej hmoo ntawm kab mob. Lub EU txwv tsis pub cov tshuaj tua kab mob loj hlob ntxiv tau ntxiv kev thov rau formic acid raws li lwm txoj hauv kev los txhawb cov tsiaj txhu noj qab haus huv.

Hauv kev lag luam tu,formic acidyog ib tug haib descaling tus neeg saib xyuas thiab ntxuav. Nws yog siv los tshem tawm cov pob zeb hauv av, xeb, thiab nplai los ntawm cov khoom siv, cov kav dej, thiab cov chaw hauv kev lag luam xws li kev tsim khoom, brewing, thiab cov khoom noj siv mis. Nws muaj txiaj ntsig tshwj xeeb ntawm kev tshem tawm cov calcium thiab magnesium deposits, uas muaj nyob rau hauv cov dej tawv. Formic acid kuj tseem siv los ntxuav cov khoom siv rau tsev neeg thiab cov chaw lag luam, xws li cov tshuaj ntxuav hauv chav dej thiab cov tshuaj tua kab mob, vim nws muaj peev xwm txiav los ntawm cov tawv nqaij tsis muaj kev puas tsuaj. Nws biodegradability ua rau nws ib puag ncig tus phooj ywg lwm txoj hauv kev ua haujlwm hnyav.

 

Rau cov lag luam thoob plaws cov kev lag luam no, formic acid yog ntau yam thiab raug nqi - cov tshuaj zoo. Nws cov ntawv thov sib txawv, ua ke nrog nws cov biodegradability thiab kev nyab xeeb (thaum ua haujlwm zoo), ua rau nws muaj txiaj ntsig zoo. Kev muab cov khoom zoo - zoo formic acid uas ua tau raws li cov qauv kev lag luam ua kom pom kev ua tau zoo thiab ua raws li cov cai ntawm ib puag ncig, pab cov lag luam txhim kho kev ua haujlwm thiab kev ruaj khov.
