Intshayelelo yemveliso kunye neempawu zayo

I-N-hydroxymethylacrylamide yipowder emhlophe ekristale. Ubuninzi bayo yi-1.185(23/4 ℃), kwaye iqondo lokunyibilika yi-75℃. Kwi-solvent eqhelekileyo e-hydrophilic nayo inokunyibilika, kwi-fatty acid esters, i-acrylic acid kunye ne-methylacrylate, ukufudumeza nako kunokunyibilika okukhulu, kodwa phantse akunyibiliki kwi-hydrophobic solvents ezifana ne-hydrocarbons, ii-halogenated hydrocarbons. Ingasetyenziswa njenge-arhente yokudibanisa i-cross-linking, esetyenziswa kakhulu kwi-fibre modified resin, idayi yokucubungula, i-plastic binder, i-soil stabilizer, njl. I-molecule yemveliso ine-double bond edityaniswe neqela le-carbonyl kunye neqela le-hydroxyl methyl elisebenzayo. Yi-monomer yokudibanisa i-cross-linking esetyenziswa kakhulu ekuguquleni i-fiber, ekucubunguleni i-resin, izincamathelisi, iphepha, isikhumba, i-arhente yonyango lomphezulu wesinyithi, kwaye ingasetyenziswa njengolungiso lomhlaba.

sebenzisa

Yinto eluhlaza esetyenziselwa ukwenza i-thermosetting resin, i-epoxy resin coating light curing, i-oil resin coating kunye ne-drying coating. I-copolymerization emulsion yayo isetyenziselwa ukugqiba i-fiber, ilaphu, isikhumba kunye nephepha. Ikwasetyenziswa njengesincamathelisi somthi, isinyithi, njl.njl.
Isetyenziswa njenge-monomer edityanisiweyo kwi-acrylic emulsion. Umlinganiselo we-acrylic emulsion pressure adhesive adhesive equlathe iqela le-carboxyl yi-L % ~ 2% yobunzima be-monomer iyonke, ukuba ingaphezulu kwe-3%, i-viscosity yokuqala iya kuncipha kakhulu. Kwi-emulsion adhesive engenalo iqela le-carboxyl, umthamo oqhelekileyo awudluli kwi-5%. Ubushushu bokusabela kwe-MMAM crosslinking kuphela buphezulu, ngokubanzi yi-120 ~ 170℃, ukongeza i-catalyst yohlobo lwe-proton kunokunciphisa ubushushu be-crosslinking. I-Acrylic acid (AA) inokubonelela ngee-hydrogen protons, kunye ne-copolymerization nge-acrylate, ngoko ke i-MMAM yokwenza i-composite crosslinking agent ene-AA, ubungakanani be-3:2 bungcono. I-cross-linker HA inokuthatha indawo ye-N-hydroxymethylacrylamide kwaye ayinayo i-formaldehyde.

iphakheji kunye nothutho

B. Le mveliso ingasetyenziswa, iingxowa ezingama-25KG,
C. Gcina ivalwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi. Izikhongozeli mazivalwe kakuhle emva kokusetyenziswa ngakunye ngaphambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthuthwa ukuze kuthintelwe ukufuma, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ukuba zingaxubeki.
