Kev Siv
Cov kev siv loj rau itaconic acid yog nyob rau hauv copolymerizations, resins, plasticizers, thiab ua lube roj additives.
Itaconic acid yog siv rau hauv kev npaj ntawm acrylonitrile-butadiene-styrene thiab acrylate latexes. Nws kuj tseem siv los npaj poly-itaconic acid, resins biofuel Cheebtsam thiab ionomer cements. Nws pom daim ntawv thov hauv kev lag luam textile, tshuaj lom neeg thiab tshuaj. Nws kuj tseem siv ua ib qho additive hauv cov fibers thiab ion pauv resins kom nce abrasion, waterproofing, lub cev tsis kam, dying affinity thiab zoo dua ntev. Ntxiv mus, nws ua raws li ib tug co-monomer siv nyob rau hauv kev npaj ntawm acrylic fibers thiab roj hmab, reinforced iav fiber, dag pob zeb diamond thiab lens. Ntxiv rau qhov no, nws ua raws li ib tug binder thiab sizing tus neeg sawv cev nyob rau hauv cov tsis-weaving fibers.
