Khoom Taw Qhia thiab Nta
N-hydroxymethylacrylamide yog hmoov dawb dawb. Cov txheeb ze ceev yog 1.185 (23/4 ℃), thiab lub ntsiab lus melting yog 75. Nyob rau hauv dav dav hydrophilic huab cua kuj tseem tuaj yeem yaj, rau kev siv tshuaj pleev li cas, tab sis yuav luag Inydrophobic cov kuab tshuaj xws li hydrocarbons, halogenated hydrocarbons. Yuav siv tau los ua tus neeg sawv cev hla, cov khoom siv zas ntoo yas ntawm cov khoom lag luam muaj cov pab pawg carbonylated nrog carbonyyl metalyl pawg. Nws yog tus ntoo khaub lig-txuas monomer siv rau cov neeg sawv cev fiber ntau, cov ntawv nplaum, tawv, hlau nto sib txuas lus hloov kho.
kev siv
Nws yog cov khoom siv raw rau kev tsim cov tshuab thermosetting, lub teeb kho epoxy resin txheej, roj resist hlua thiab ziab. Nws cov ntawv luam tawm emulsion siv rau cov xov fiber ntau, cov ntaub, tawv thiab ntawv txheej. Nws tseem siv los ua cov nplaum rau ntoo, hlau, thiab lwm yam.
Siv ua tus ntoo khaub lig-txuas monomer rau acrylic emulsion. Cov tshuaj pleev ntawm Acrylic Emulsion siab cov nplaum uas muaj cov qauv nplaum muaj l% Rau cov nplaum pleev cov nplaum tsis muaj cov pab pawg carboxyl, cov kev ntsuas kev tiv thaiv tsis ntau tshaj 5%. MMAM Crosslinking cov tshuaj tiv thaiv kub ib leeg yog qhov siab dua, feem ntau 120 ~ 170 ℃, ntxiv cov tshuaj tiv thaiv protonniv tuaj yeem txo cov ntoo khaub lig. Acrylic acid (AA) muaj peev xwm ob qho tib si muab cov protons hydrogenizies, thiab MMAM los ua tus neeg muaj kev sib xyaw nrog AA, tus nqi ntawm 3: 2 zoo dua. Tus ntoo khaub lig-linker ha tuaj yeem hloov n-hydroxymethylacrylamide thiab tsis muaj formaldehyde.
Pob Thiab Thauj
B. Cov khoom lag luam no tuaj yeem siv, 25kg, hnab
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
