Itaconic Acid (tseem hu ua Methylene Succinic Acid) yog dawb crystalline carboxylic acid tau los ntawm fermentation ntawm carbohydrates. Nws yog soluble hauv dej, ethanol thiab acetone. Unsaturated solid bond ua rau kev sib txuas nrog cov pa roj carbonly pawg. Nws yog siv nyob rau hauv lub teb ntawm;
● Co-monomer los npaj cov acrylic fibers thiab cov roj hmab, cov iav fiber ntau ntxiv, cov pob zeb diamond thiab lub lens
● Additive nyob rau hauv fibers thiab ion pauv resins kom nce puas, waterproofing, lub cev tsis kam, tuag affinity thiab zoo sij hawm.
● Kev kho dej los tiv thaiv kev kis kab mob los ntawm cov hlau alkali
● Raws li binder thiab sizing tus neeg sawv cev nyob rau hauv non-weaving fibers, ntawv thiab qhob xim
Daim ntawv thov kawg ntawm itaconic acid thiab nws cov esters suav nrog hauv thaj chaw ntawm co-polymerizations, plasticizers, roj nplua nyeem, ntawv txheej. cov ntaub pua plag rau lub sijhawm zoo dua, cov nplaum nplaum, txheej txheej, xim, thickener, emulsifier, cov neeg ua haujlwm saum npoo av, tshuaj thiab tshuaj luam ntawv.
