Kev taw qhia txog khoom thiab nta

N-hydroxymethylacrylamide yog ib hom hmoov dawb crystalline. Qhov ceev ntawm cov tshuaj yog 1.185 (23/4 ℃), thiab qhov melting point yog 75 ℃. Hauv cov hydrophilic solvent feem ntau kuj tuaj yeem yaj, rau cov fatty acid esters, acrylic acid thiab methylacrylate, cua sov kuj muaj solubility ntau, tab sis yuav luag tsis yaj hauv cov hydrophobic solvents xws li hydrocarbons, halogenated hydrocarbons. Siv tau ua tus neeg sawv cev sib txuas, siv dav hauv fiber modified resin, ua cov xim zas, yas binder, av stabilizer, thiab lwm yam. Lub molecule ntawm cov khoom muaj ob chav sib txuas nrog carbonyl pawg thiab reactive hydroxyl methyl pawg. Nws yog ib qho monomer sib txuas dav dav siv rau fiber modification, ua resin, nplaum, ntawv, tawv, hlau surface treatment agent, thiab kuj siv tau ua av modification.

siv

Nws yog ib yam khoom siv raw rau kev tsim cov thermosetting resin, lub teeb kho epoxy resin txheej, roj-resistant txheej thiab ziab txheej. Nws cov copolymerization emulsion yog siv rau kev ua tiav fiber, ntaub, tawv thiab ntawv txheej. Nws kuj tseem siv tau ua cov nplaum rau ntoo, hlau, thiab lwm yam.
Siv ua ib qho cross-linked monomer rau acrylic emulsion. Cov tshuaj acrylic emulsion uas muaj carboxyl pawg yog L% ~ 2% ntawm tag nrho cov monomer pawg, yog tias ntau dua 3%, qhov pib viscosity yuav raug txo qis heev. Rau cov emulsion nplaum uas tsis muaj carboxyl pawg, cov tshuaj feem ntau tsis pub ntau tshaj 5%. MMAM crosslinking reaction kub ib leeg siab dua, feem ntau 120 ~ 170 ℃, ntxiv cov proton-type catalyst tuaj yeem txo qhov kub crosslinking. Acrylic acid (AA) tuaj yeem muab cov hydrogen protons, thiab copolymerization nrog acrylate, yog li MMAM los tsim ib qho composite crosslinking agent nrog AA, qhov ntau ntawm 3: 2 zoo dua. Tus cross-linker HA tuaj yeem hloov N-hydroxymethylacrylamide thiab tsis muaj formaldehyde.

pob khoom thiab kev thauj mus los

B. Cov khoom no siv tau, 25KG, hnab
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
