Sumo yechigadzirwa uye maficha azvo

N-hydroxymethylacrylamide ipfu chena yekristaro. Huwandu hwayo i1.185(23/4 ℃), uye poindi yekunyunguduka i75℃. Mu hydrophilic solvent inogonawo kunyungudutswa, kune fatty acid esters, acrylic acid uye methylacrylate, kupisa kunewo kunyunguduka kwakanyanya, asi hakunyunguduki mu hydrophobic solvents dzakadai sehydrocarbons, halogenated hydrocarbons. Inogona kushandiswa se cross-linking agent, inoshandiswa zvakanyanya mu fiber modified resin, processing dye, plastic binder, soil stabilizer, nezvimwewo. Molekyuri yechigadzirwa ine double bond yakabatana ne carbonyl group uye reactive hydroxyl methyl group. I cross-linking monomer inoshandiswa zvakanyanya pakugadzirisa fiber, resin processing, adhesives, bepa, dehwe, simbi surface treatment agent, uye inogonawo kushandiswa se soil amendment.

shandisa

Inoshandiswa kugadzira resin inodziya, epoxy resin inopenya, coating inotsungirira mafuta uye drying coating. Copolymerization emulsion yayo inoshandiswa pakupedzisa fiber, jira, dehwe uye paper coating. Inoshandiswawo se namatidziro yehuni, simbi, nezvimwewo.
Inoshandiswa semonomer ine cross-linked yeacrylic emulsion. Chiyero che acrylic emulsion pressure sensitive adhesive ine carboxyl group iL % ~ 2% yehuwandu hwe monomer, kana inopfuura 3%, viscosity yekutanga ichaderedzwa zvakanyanya. Kune emulsion adhesive isina carboxyl group, chiyero chakajairika hachipfuure 5%. MMAM crosslinking reaction tembiricha yega yakakwira, kazhinji 120 ~ 170℃, kuwedzera proton-type catalyst kunogona kuderedza tembiricha ye crosslinking. Acrylic acid (AA) inogona kupa hydrogen protons, uye copolymerization ne acrylate, saka MMAM kuti igadzire composite crosslinking agent neAA, huwandu hwe3:2 huri nani. Cross-linker HA inogona kutsiva N-hydroxymethylacrylamide uye haina formaldehyde.

B. Chigadzirwa ichi chinogona kushandiswa, 25KG, MABHAGI
C. Chengeta yakavharwa munzvimbo inotonhorera, yakaoma uye ine mhepo mukati. Midziyo inofanira kuvharwa zvakasimba mushure mekushandisa kwega kwega usati washandisa.
D. Chigadzirwa ichi chinofanira kuvharwa zvakanaka panguva yekufambisa kudzivirira hunyoro, alkali yakasimba uye acid, mvura nezvimwe tsvina kuti zvisasanganiswe.
