Ukwethulwa komkhiqizo nezici

I-N-hydroxymethylacrylamide iyimpuphu emhlophe ye-crystalline. Isimo esilinganiselwe ngu-1.185 (23/4 ℃), nephuzu lokuncibilika lingu-75 ℃. Ku-general hydrophilic solvent nayo ingachithwa, kuma-fatty acid esters, i-acrylic acid ne-methylayicrylate, ukufudumala nakho kune-soubelity enkulu, kepha kucishe kube yi-solubility, kodwa kucishe kube yi-infolfobic solvents as hydrocobic solvents as hydrocarbons, halogened hydrocarbons. Ingasetshenziswa njengomenzeli oxhumanisayo, esetshenziswa kabanzi ku-fiber moviefied resin, ukucubungula udayi, i-spinder yepulasitiki, i-molecule yomkhiqizo ihlanganiswe ne-condwork ye-Carbonyl ne-hydroxyl throm. Kuyinto monomer exhumanisa kakhulu esetshenziselwa ukuguqulwa kwefayibha, ukucubungula kabusha, ukunamathela, iphepha, isikhumba, i-ejenti yokwelashwa komhlaba, futhi nayo ingasetshenziswa njengokuchitshiyelwa kwenhlabathi.

umsebenzi

Kuyinto ebonakalayo yokwenziwa kwe-thermosetting resin, ukukhanya elapha ama-epoxy epoxy epoxy resin, ukumelana kwamafutha okumelana nowomisa. I-emulsion yayo ye-copolymerization isetshenziselwa ukuqeda i-fiber, indwangu, isikhumba kanye ne-paper coating. Iphinde isetshenziswe njenge-adhesive ngokhuni, insimbi, njll.
Isetshenziswa njenge-monomer exhumeke ngokuqondile ye-acrylic emulsion. Umthamo we-acrylic emulsion ingcindezi yokuhlobisa okunamandla aqukethe iqembu le-carboxyl ngu-l% ~ 2% we-contral monomer mass, uma kungaphezulu kwama-3%, ukubonwa kokuqala kuzoncishiswa kakhulu. Ukuze i-emulsion inamathela ngaphandle kwe-carboxyl group, umthamo jikelele awubi ngaphezu kwe-5%. I-Mmam Crosslinking Mearte lokushisa lilodwa liphezulu, ngokuvamile 120 ~ 170 ℃, engeza uhlobo lwe-proton-hlobo lunganciphisa izinga lokushisa lokuwela. I-acrylic acid (AA) Can anikeze ama-hydrogen protons, kanye ne-copolymerization nge-acrylate, ngakho-ke mmam ukwakha i-ejenti yokuwela i-corsosite nge-AA, inani le-3: 2 lingcono. I-hain-licker ha ingathatha isikhundla se-n-hydroxymethylacrylamide futhi ayiqukethe i-formaldehyde.

iphakheji nokuhamba

B. Lo mkhiqizo ungasetshenziswa, ama-25kg, izikhwama
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
