Fumaric acid, nrog rau cov tshuaj formula C4H4O4, yog carboxylic acid muab los ntawm butene thiab yog ib tug tsis muaj kob, flammable siv lead ua.
Nws yog dav siv nyob rau hauv ntau lub teb xws li cov hauv qab no:
Fumaric acid tuaj yeem siv los ua zaub mov acidifier hauv kev ua zaub mov txhawm rau txhim kho acidity thiab saj ntawm zaub mov. Nws cov acidity yog li ntawm 1.5 npaug ntawm citric acid, yog li nws tau siv dav hauv cov khoom noj khoom haus. Fumaric acid kuj muaj qee yam antioxidant zog, uas tuaj yeem ua rau lub neej txee ntawm cov zaub mov. Fumaric acid kuj tseem siv tau los ua cov tshuaj tua kab mob los pab tiv thaiv kev loj hlob ntawm cov kab mob hauv cov zaub mov, tswj nws cov tshiab thiab kev nyab xeeb.
kev siv tus nqi pub.
Hauv kev tsim tshuaj, fumaric acid tuaj yeem siv los ua cov khoom xyaw rau tshuaj thiab khoom noj qab haus huv. Nws plays ib qho tseem ceeb catalytic thiab stabilizing lub luag hauj lwm nyob rau hauv lub tsim ntawm tej yam tshuaj, thiab yog siv nyob rau hauv zus tau tej cov sustained-tso formulations, vitamins, tshuaj qhov ncauj, thiab lwm yam khoom.
Hauv kev lag luam chemical engineering, fumaric acid tau siv dav hauv kev tsim cov khoom siv tsis zoo polyester resins, alkyd resins, thiab lwm yam. Cov resins muaj cov ntawv tseem ceeb hauv cov teb xws li coatings, adhesives, thiab composite cov ntaub ntawv. Hauv kev ua hlau, fumaric acid tuaj yeem siv los ua cov kua qaub ntxuav kom tshem tawm cov oxides thiab xeb ntawm cov hlau nto, txhim kho kev huv ntawm cov hlau nto, thiab txhim kho cov nyhuv tom qab.
Fumaric acid, pub additive, yuav siv tau raws li pub acidifier kom acidity ntawm cov tsiaj nyeg thiab nqaij qaib gastric kua txiv, yog li txhawb kev zom thiab nqus ntawm pub los ntawm cov tsiaj nyeg thiab nqaij qaib, thiab txhim kho

Feature ntawmFumaric acid:
- Muaj zog affinity: Fumaric acid tuaj yeem nkag mus rau hauv lub cev sai thiab "sib tham" nrog lub plawv, pab nws rov zoo thiab ua kom pom tias nws muaj kev sib raug zoo rau lub plawv.
- Kev ua tau zoo me me: Tsis zoo li qee cov tshuaj muaj zog, fumaric acid muaj cov nyhuv me me thiab tsis ua rau lub cev hnyav dhau.
- Kev nqus tau siab: Fumaric acid muaj qhov nqus ntawm cov hnyuv uas ntau zaus ntawm ferrous sulfate, tsis cuam tshuam nrog kev nqus ntawm lwm cov ntsiab lus, muaj kev sib raug zoo nrog ntau yam khoom noj thiab tshuaj tua kab mob, thiab muaj kev sib koom ua ke.
- Cov tshuaj lom neeg muaj zog: Fumaric acid tuaj yeem tiv thaiv kev puas tsuaj ntawm cov tshuaj nquag xws li cov vitamins los ntawm kev sib ntxiv ntawm cov hlau tsis muaj zog, koom nrog kev tsim thiab ua kom muaj ntau yam enzymes hauv lub cev, txhim kho kev tiv thaiv kab mob, txhawb kev loj hlob, thiab txhim kho kev nyuaj siab thiab kab mob tiv thaiv.
