Intshayelelo yemveliso kunye neempawu
I-N-hydroxymethylacrylamide ngumgubo omhlophe wekristale.Uxinzelelo olunxulumeneyo yi-1.185(23/4 ℃), kwaye indawo yokunyibilika yi-75℃.Kwi-solvent jikelele ye-hydrophilic nayo inokunyibilika, kwi-esters ye-asidi enamafutha, i-acrylic acid kunye ne-methylacrylate, ukufudumeza kukwanokunyibilika okukhulu, kodwa phantse kunganyibiliki kwizinyibilikisi ze-hydrophobic ezifana nee-hydrocarbons, ii-halogenated hydrocarbons.Ingasetyenziselwa njenge-agent edibanisayo, isetyenziswe ngokubanzi kwi-fiber modified resin, idayi yokucubungula, i-plastic binder, i-stabilizer yomhlaba, njl.Yi-monomer edibanisa umnqamlezo esetyenziswa ngokubanzi ukuguqulwa kwefayibha, ukusetyenzwa kwe-resin, i-adhesives, iphepha, isikhumba, i-agent yonyango yomgangatho wesinyithi, kwaye inokusetyenziswa njengesilungiso somhlaba.
sebenzisa
Yimathiriyeli ekrwada yokwenziwa kweresin ye-thermosetting, ukukhanya okuphilisa i-epoxy resin coating, i-oyile enganyangekiyo yokwaleka kunye nokwaleka ukomisa.I-emulsion yayo ye-copolymerization isetyenziselwa ukugqiba ifayibha, ilaphu, isikhumba kunye nephepha lokutyabeka.Ikwasetyenziswa njenge-adhesive yomthi, isinyithi, njl.
Isetyenziswe njenge-monomer edibeneyo edibeneyo ye-acrylic emulsion.Umthamo we-acrylic emulsion yoxinzelelo lwe-adhesive enamathelayo eneqela le-carboxyl yi-L% ~ 2% ye-monomer mass iyonke, ukuba ngaphezu kwe-3%, i-viscosity yokuqala iya kuncitshiswa kakhulu.Kwi-adhesive ye-emulsion ngaphandle kweqela le-carboxyl, umthamo jikelele awukho ngaphezu kwe-5%.Iqondo lobushushu le-MMAM crosslinking reaction lilodwa liphezulu, ngokuqhelekileyo li-120 ~ 170 ℃, ukongeza i-proton-type catalyst inokunciphisa ubushushu bokudibanisa.I-Acrylic acid (AA) inokubonelela zombini iiprotoni ze-hydrogen, kunye ne-copolymerization nge-acrylate, ngoko i-MMAM yenze i-agent ye-crosslinking edibeneyo kunye ne-AA, inani le-3: 2 lingcono.I-cross-linker HA ingathatha indawo ye-N-hydroxymethylacrylamide kwaye ayinayo i-formaldehyde.
iphakheji kunye nezithuthi
B. Le mveliso ingasetyenziswa, 25KG, BAGS
C. Gcina uvalelwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi.Imigqomo kufuneka ivalwe ngokuqinileyo emva kokusetyenziswa ngakunye phambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthutha ukukhusela umswakama, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ekuxubeni.
