Thoob Ntiaj Teb - Premier Formic Acid: Lub Zog Tshuaj Lom Zem Uas Hloov Pauv Kev Lag Luam-1
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam tawv, peb cov formic acid yog qhov hloov pauv tiag tiag. Nws ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tanning. Thaum siv rau hauv kev tsim tawv, nws pab kho cov pH ntawm cov chaw da dej tanning. Qhov no tsis yog tsuas yog ua kom cov txheej txheem tanning sai dua xwb tab sis kuj ua kom muaj kev faib tawm ntawm cov neeg sawv cev tanning thoob plaws tawv. Qhov tshwm sim? Tawv uas mos dua, ruaj dua, thiab muaj xim sib xws dua. Txawm hais tias nws yog rau cov khoom tawv zoo nkauj xws li hnab tes thiab khau lossis tawv qib kev lag luam rau siv thiab siv, peb cov formic acid yog qhov tseem ceeb rau kev tsim cov khoom tawv zoo tshaj plaws.
Kev lag luam roj hmab kuj tau txais txiaj ntsig zoo los ntawm peb lub Global - Premier Formic Acid. Nws yog siv ua cov tshuaj coagulant hauv kev tsim cov roj hmab ntuj. Thaum ntxiv rau hauv latex, nws ua rau cov txheej txheem coagulation, cais cov roj hmab ntawm cov kua latex uas yog dej. Qhov no pab cov neeg tsim roj hmab kom sau thiab ua cov roj hmab ntuj tau zoo. Los ntawm kev siv peb cov formic acid, lawv tuaj yeem ua kom muaj cov roj hmab zoo dua, uas yog qhov tseem ceeb rau kev tsim cov log tsheb, cov kav roj hmab, thiab ntau yam khoom siv roj hmab.
Hauv kev lag luam ua liaj ua teb, formic acid muaj lub luag haujlwm tseem ceeb heev. Nws yog siv ua cov khoom noj ntxiv rau tsiaj txhu. Formic acid pab khaws cov silage los ntawm kev tiv thaiv kev loj hlob ntawm cov kab mob thiab pwm tsis zoo. Qhov no ua kom cov tsiaj txhu cov zaub mov tseem tshiab thiab muaj txiaj ntsig zoo rau lub sijhawm ntev dua. Rau cov neeg ua liaj ua teb, qhov no txhais tau tias cov khoom noj pov tseg tsawg dua thiab cov tsiaj noj qab haus huv zoo dua. Tsis tas li ntawd, qee zaum, formic acid kuj tseem tuaj yeem txhim kho kev zom zaub mov, ua rau cov tsiaj txhu hnyav dua.
Hauv kev lag luam tsim tshuaj lom neeg, peb cov kua qaub formic ua haujlwm ua lub hauv paus tseem ceeb rau kev tsim ntau yam tshuaj lom neeg. Nws yog siv rau hauv kev tsim cov esters, uas siv dav hauv kev lag luam tshuaj tsw qab thiab tsw qab. Cov khoom siv tshuaj lom neeg tshwj xeeb ntawm cov kua qaub formic ua rau muaj kev tsim cov esters nrog cov ntxhiab tsw thiab saj sib txawv thiab nyiam. Nws kuj tseem siv rau hauv kev tsim cov polymers, pab txhawb rau kev tsim cov khoom siv tshiab thiab tshiab.
