Isingeniso somkhiqizo kanye nezici

I-N-hydroxymethylacrylamide iyimpushana ecwebezelayo emhlophe.Ukuminyana okuhlobene ngu-1.185(23/4 ℃), futhi indawo encibilikayo ingu-75℃.Ngokujwayelekile i-solvent ye-hydrophilic nayo ingancibilika, ngama-fatty acid esters, i-acrylic acid ne-methylacrylate, ukufudumeza nakho kune-solubility enkulu, kodwa cishe akuncibiliki kuzinyibilikisi ze-hydrophobic ezifana nama-hydrocarbon, ama-halogenated hydrocarbons.Ingasetshenziswa njenge-ejenti yokuxhumanisa, esetshenziswa kabanzi ku-fiber modified resin, udayi wokucubungula, i-plastic binder, isinzisi senhlabathi, njll. I-molecule yomkhiqizo inesibopho esiphindwe kabili esihlanganiswe neqembu le-carbonyl kanye neqembu le-hydroxyl methyl elisebenzayo.Kuyi-monomer exhumanisa kakhulu esetshenziswa kabanzi ukuguqulwa kwefayibha, ukucutshungulwa kwe-resin, okunamathelayo, iphepha, isikhumba, i-ejenti yokwelapha ebusweni bensimbi, futhi ingasetshenziswa njengesichibiyelo senhlabathi.

sebenzisa

Kuyimpahla eluhlaza yokwenziwa kwe-thermosetting resin, ukukhanya okuphulukisa i-epoxy resin coating, ukunamathela ku-oyela ukumelana nowoyela nokomisa.I-emulsion yayo ye-copolymerization isetshenziselwa ukuqeda i-fiber, indwangu, isikhumba nephepha.Ibuye isetshenziswe njenge-adhesive ngokhuni, insimbi, njll.
Isetshenziswa njenge-monomer exhunywe esiphambanweni ye-emulsion ye-acrylic.Umthamo we-acrylic emulsion pressure ebucayi yokunamathisela equkethe iqembu le-carboxyl ngu-L% ~ 2% yenani le-monomer mass, uma ngaphezu kuka-3%, i-viscosity yokuqala izoncishiswa kakhulu.Ngokunamathela kwe-emulsion ngaphandle kweqembu le-carboxyl, umthamo ojwayelekile awudluli ku-5%.I-MMAM crosslinking reaction temperature iyodwa iphakeme, ngokuvamile i-120 ~ 170℃, ukwengeza i-catalyst yohlobo lwe-proton kunganciphisa izinga lokushisa elixhumanisayo.I-Acrylic acid (AA) ingahlinzeka kokubili ngamaphrothoni e-hydrogen, kanye ne-copolymerization nge-acrylate, ukuze i-MMAM yakhe i-ejenti ehlanganisayo eyinhlanganisela nge-AA, inani elingu-3:2 lingcono.I-cross-linker HA ingangena esikhundleni se-N-hydroxymethylacrylamide futhi ayiqukethe i-formaldehyde.

iphakethe kanye nezokuthutha

B. Lo mkhiqizo ungasetshenziswa, 25KG, AMAsaka
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
