Isingeniso somkhiqizo kanye nezici

I-N-hydroxymethylacrylamide iyimpuphu emhlophe ekristalu. Ubuningi obuhlobene buyi-1.185(23/4 ℃), kanti iphuzu lokuncibilika lingu-75℃. Ku-solvent ejwayelekile e-hydrophilic nayo ingancibilika, kuma-ester e-fatty acid, i-acrylic acid kanye ne-methylacrylate, ukushisa nakho kunokuncibilika okukhulu, kodwa cishe akuncibiliki ezincibilikisini ezincibilikisini ezincibilikisini ezincibilikisini ezinjengama-hydrocarbon, ama-hydrocarbon ane-halogenated. Ingasetshenziswa njenge-ejenti yokuxhumanisa, esetshenziswa kabanzi ku-resin eguquliwe ye-fiber, udayi wokucubungula, i-plastic binder, i-soil stabilizer, njll. I-molecule yomkhiqizo inesibopho esiphindwe kabili esihlanganiswe neqembu le-carbonyl kanye neqembu le-hydroxyl methyl elisebenzayo. Iyi-monomer yokuxhumanisa esetshenziswa kabanzi ekuguqulweni kwe-fiber, ekucubungulweni kwe-resin, izinamathiseli, iphepha, isikhumba, i-ejenti yokwelapha ubuso bensimbi, futhi ingasetshenziswa futhi njengokulungiswa kwenhlabathi.

sebenzisa

Kuyinto eluhlaza yokwenziwa kwe-thermosetting resin, i-epoxy resin ekhazimulayo, i-coating evikela uwoyela kanye ne-drying coating. I-copolymerization emulsion yayo isetshenziselwa ukuqeda i-fiber, indwangu, isikhumba kanye ne-paper coating. Iphinde isetshenziswe njenge-glue yokhuni, insimbi, njll.
Isetshenziswa njenge-monomer exhunywe nge-cross-linked ye-acrylic emulsion. Umthamo we-acrylic emulsion pressure adhesive adhesive adhesive equkethe iqembu le-carboxyl u-L % ~ 2% we-monomer mass iyonke, uma ingaphezu kuka-3%, i-viscosity yokuqala izoncishiswa kakhulu. Kwi-emulsion adhesive ngaphandle kweqembu le-carboxyl, umthamo ojwayelekile awudluli ku-5%. Izinga lokushisa lokusabela kwe-MMAM crosslinking kuphela liphakeme, ngokuvamile liyi-120 ~ 170℃, ukwengeza i-catalyst yohlobo lwe-proton kunganciphisa izinga lokushisa le-crosslinking. I-Acrylic acid (AA) inganikeza ama-proton e-hydrogen, kanye ne-copolymerization nge-acrylate, ngakho-ke i-MMAM ukwakha i-agent ehlanganisiwe ye-crosslinking ene-AA, inani elingu-3:2 lingcono. I-cross-linker HA ingathatha indawo ye-N-hydroxymethylacrylamide futhi ayinayo i-formaldehyde.

iphakheji kanye nokuthuthwa

B. Lo mkhiqizo ungasetshenziswa, 25KG, IZINGXEBA
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
