Khoom Description
Fumaric Acid yog nyob rau hauv cov duab ntawm cov xim tsis muaj xim, uas muaj nyob rau hauv ntau hom nceb thiab nqaij nyuj tshiab. Fumaric Acid tuaj yeem siv rau hauv kev tsim cov khoom siv tsis zoo polyester resins. Fumaric acid yog cov khoom noj acidulent siv tau ntev vim nws tsis muaj tshuaj lom. Raws li cov khoom noj ntxiv, Fumaric Acid yog cov khoom noj khoom haus tseem ceeb hauv peb cov khoom noj. Raws li ib tug ua zaub mov additives thiab cov khoom xyaw zaub mov nyob rau hauv Suav teb, peb yuav muab tau koj zoo Fumaric Acid.
Siv ua acidulant, Fumaric Acid muaj bacteriostatic thiab antiseptic muaj nuj nqi. Nws kuj tuaj yeem siv los ua acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant thiab txuj lom. Siv los ua cov tshuaj acidic ntawm effervescent tus neeg sawv cev, nws tuaj yeem tsim ua npuas ntev thiab zoo nkauj. Fumaric acid tuaj yeem siv ua tshuaj nruab nrab thiab kho qhov muag bleaching tus neeg sawv cev. Hauv kev lag luam tshuaj, nws yog siv los tsim alexipharmic sodium dimercaptosuccinate thiab ferrous fumarate. Fumaric acid kuj tseem siv rau hauv kev tsim cov khoom siv tsis zoo polyester.
Function & Application
Fumaric acid muaj bacteriostatic thiab antiseptic muaj nuj nqi, nws yuav siv tau raws li acidulant, acidity regulator, acidifier, thermal-oxidative tiv thaiv auxiliary, curing accelerant thiab txuj lom. Widly siv los ua ntau yam carbonic acid haus, cawv, concentrated dej haus, ice cream thiab lwm yam khoom noj txias thiab dej haus. Nws tuaj yeem hloov malic acid, citric acid, rau nws cov acidity degree yog 1. 5 npaug ntawm citric acid.
