2,2-Dimethylolbutanoic acid (DMBA) yog neopentyl carboxylic acid nrog ob pawg hydroxymethyl reactive, yog li nws tuaj yeem siv ua cov dej-raws li polymer systems thiab dav siv hauv dej-soluble polyurethane, polyester thiab epoxy resin system.
DMBA muaj kev yaj zoo dua li lwm cov khoom siv raw. DMPA nyob rau hauv cov kuab tshuaj sib txawv, yog li nws tuaj yeem txhim kho kev ua haujlwm zoo heev.
DMBA raug suav hais tias yog ib tiam tshiab ntawm cov khoom siv txuas ntxiv rau cov saw hlau ntsuab & ib puag ncig thiab cov emulsifier sab hauv rau cov dej-raws li polyurethane; Nws tuaj yeem siv rau hauv kev tsim cov kua nplaum polyurethane uas tsis tas siv cov kuab tshuaj organic thiab muab xoom cov organic residues. Nws daws cov teeb meem ntawm DMPA xws li qhov chaw yaj siab, yaj qeeb, lub sijhawm teb ntev, siv zog ntau, ua haujlwm tsis zoo, xav tau cov kuab tshuaj organic, cov kuab tshuaj seem loj thiab lwm yam.
Nws kuj tseem siv tau rau kev tsim cov dej-raws li epoxy resin thiab polyester adhesives.
Tam sim no, nws yog qhov zoo tshaj plaws multipurposed hloov kho auxiliary (hydrophilic saw extender) ntawm polyurethane, dej-raws li resins, dej-raws li adhesives, dej-raws li xim thiab lwm yam dej-raws li cov khoom; raws li ib tug monomer rau cov txheej txheem ntawm kev hloov kho, Dimethylolbutanoic acid (DMBA) tsis xav tau organic solvents (dej hloov), yog li ntawd cov txheej txheem ntau lawm yog yooj yim dua thiab muaj stabler thiab zoo tshaj plaws kev ua tau zoo. Tshwj xeeb tshaj yog, DMPA(dimethylolpropionic acid) tam sim no tau dhau los ua cov khoom nrov tshaj plaws hauv thaj chaw dej rau kev ua tau zoo heev!
