2,2-Dimethylolbutanoic acid (DMBA) yog neopentyl carboxylic acid nrog ob pawg hydroxymethyl reactive, yog li nws tuaj yeem siv los ua cov khoom siv dej-raws li polymer systems thiab dav siv hauv dej-soluble polyurethane, polyester thiab epoxy resin system.
DMBA muaj zoo solubility duaDMPAhauv cov kuab tshuaj sib txawv, yog li nws tuaj yeem txhim kho kev ua haujlwm zoo.
DMBA yog suav tias yog ib tiam tshiab ntawm ntsuab & ib puag ncig-phooj ywg saw txuas ntxiv thiab sab hauv emulsifier rau dej-raws li polyurethane; Nws tuaj yeem siv rau hauv kev tsim cov aqueous polyurethane adhesives tsis siv cov kuab tshuaj organic thiab muab xoom organic residues. Nws daws qhov txhaum ntawmDMPAxws li siab melting point, qeeb dissolution, ntev cov tshuaj tiv thaiv lub sij hawm, siab zog noj, tsis zoo cov khoom, kev xav tau ntawm cov organic solvents, loj hnyav residual ntim thiab hais txog.
Nws kuj tuaj yeem siv rau kev tsim cov dej-raws li epoxy resin thiab polyester nplaum.
Tam sim no, nws yog qhov zoo tshaj plaws multipurposed modified auxiliary (hydrophilic chain 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) xav tau tsis muaj cov kuab tshuaj organic (dej hloov), yog li cov txheej txheem tsim khoom yooj yim dua thiab muaj kev ruaj khov thiab ua haujlwm zoo tshaj plaws. Tshwj xeeb,DMPA(dimethylolpropionic acid) tam sim no tau dhau los ua cov khoom lag luam nrov tshaj plaws hauv dej-raws li kev ua haujlwm zoo heev!
