Kusuma chigadzirwa uye maitiro
N-hydroxymethylacrylamide ichena crystalline poda.Density yehukama ndeye 1.185 (23/4 ℃), uye nzvimbo yekunyungudika i75 ℃.Muzhinji hydrophilic solvent inogonawo kunyungudika, yemafuta asidhi esters, acrylic asidhi uye methylacrylate, kudziyisa ine solubility yakakura, asi inenge isinganyungudika muhydrophobic solvents senge hydrocarbons, halogenated hydrocarbons.Inogona kushandiswa se-cross-linking agent, inoshandiswa zvakanyanya mu fiber modified resin, kugadzirisa dhayi, plastiki binder, ivhu rakagadzikana, etc. Iyo molecule yechigadzirwa ine kaviri bond conjugated ne carbonyl boka uye reactive hydroxyl methyl boka.Iyo muchinjika-inobatanidza monomer inonyanya kushandiswa kugadziridza faibha, resin kugadzirisa, zvinonamira, bepa, dehwe, simbi pamusoro pekurapa mumiririri, uye inogona zvakare kushandiswa sekugadzirisa ivhu.
use
Icho chinhu chakasvibirira chekugadzirwa kwe thermosetting resin, mwenje wekurapa epoxy resin coating, mafuta anodzivirira coating uye kuomesa coating.Yayo copolymerization emulsion inoshandiswa kune fiber kupedzisa, machira, dehwe uye bepa rekuta.Inoshandiswawo sechinamira chehuni, simbi, nezvimwe.
Inoshandiswa semuchinjiko-yakabatana monomer ye acrylic emulsion.Muyero we acrylic emulsion pressure sensitive adhesive ine carboxyl boka iL% ~ 2% yehuwandu hwemonomer mass, kana inopfuura 3%, yekutanga viscosity ichaderedzwa zvikuru.Kune emulsion adhesive pasina carboxyl boka, iyo yakawanda dosage haina kupfuura 5%.MMAM crosslinking reaction tembiricha chete yakakwira, kazhinji 120 ~ 170 ℃, kuwedzera proton-type catalyst inogona kuderedza tembiricha yekuyambuka.Acrylic acid (AA) inogona kupa ese hydrogen protons, uye copolymerization ine acrylate, saka MMAM kuumba composite crosslinking agent neAA, huwandu hwe3: 2 huri nani.Iyo cross-linker HA inogona kutsiva N-hydroxymethylacrylamide uye haina formaldehyde.
pasuru uye chokufambisa
B. Ichi chigadzirwa chinogona kushandiswa, 25KG, BAGS
C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
