Soo bandhigida alaabta iyo sifooyinka

N-hydroxymethylacrylamide waa budo crystalline cad.Cufnaanta qaraabada ah waa 1.185 (23/4 ℃), barta dhalaaliduna waa 75 ℃.Isku-darka guud ee hydrophilic sidoo kale waa lagu milmi karaa, esters acid dufan, acrylic acid iyo methylacrylate, kuleylku sidoo kale wuxuu leeyahay milmi badan, laakiin ku dhawaad ​​aan la milmi karin dareerayaasha hydrophobic sida hydrocarbons, hydrocarbons halogenated.Waxaa loo isticmaali karaa sida wakiilka iskutallaabta ah, oo si ballaaran loo isticmaalo xabagta la beddelay ee fiber-ka, dheeha farsamaynta, caagagga caagga ah, xasiliyaha ciidda, iwm.Waa monomer iskutallaabta ah oo si weyn loogu isticmaalo wax ka beddelka fiber-ka, farsamaynta resin-ka, xabagta, xaashida, maqaar, wakiilka daawaynta dusha birta, waxaana sidoo kale loo isticmaali karaa wax ka beddelka ciidda.

isticmaal

Waa walxo ceeriin ah oo loogu talagalay soo saarista xabagta heerkulbeegga, dahaarka resin epoxy ee fudud, daahan saliid u adkaysta iyo daahan qalajinta.Its emulsion copolymerization waxaa loo isticmaalaa dhamaystirka fiber, dhar, maqaar iyo daahan warqad.Waxa kale oo loo isticmaalaa sidii xabag ahaan alwaax, birta, iwm.
Loo isticmaalo sidii monomer-ka-xiran ee emulsion-ka akril.Qiyaasta xabagta xasaasiga ah ee emulsion acrylic oo ay ku jiraan kooxda karboksylku waa L% ~ 2% wadarta guud ee monomer, haddii in ka badan 3%, viscosity bilowga aad ayaa loo dhimi doonaa.Xabagta emulsion-ka oo aan lahayn kooxda karboksyl, qiyaasta guud kama badna 5%.Heerkulka falcelinta MMAM ee isku-tallaabta kaligeed ayaa ka sarreeya, guud ahaan 120 ~ 170 ℃, ku darista wax kicinaya nooca proton-ka waxay yarayn kartaa heerkulka is-goysyada.Acrylic acid (AA) waxay labaduba bixin karaan borotoonnada hydrogen, iyo isku-duubnida acrylate, sidaa darteed MMAM si ay u sameyso walax iskuxiran oo isku dhafan oo leh AA, qadarka 3:2 ayaa ka wanaagsan.Isku-tallaabta HA waxay bedeli kartaa N-hydroxymethylacrylamide oo kuma jiraan formaldehyde.

xirmo iyo gaadiid

B. Alaabtan waxaa loo isticmaali karaa,25KG, bacaha
C. Ku kaydi meel qabow, qalalan oo hawo leh oo gudaha ah.Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor intaan la isticmaalin.
D. Alaabtan waa in si fiican loo xiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xooggan iyo aashitada, roobka iyo wasakhda kale ee isku darka.
