Kugadziridzwa Kugadziridzwa kwekare bepa-[N-Methylol Acrylamide 98%]
Pepa, semutakuri mukuru wemapepa tsika zvisaririra, ndiyo hupfumi hwebudiriro yevanhu, kugara nhaka uye kurekodha nhoroondo, tsika uye budiriro yemweya yerudzi rweChinese.Mumakore achangopfuura, nokuda kukanganisa, dzinongoitika kuchembera, chipfukuto-akadyiwa chakuvhe, nhamba huru bepa akaonekwa zvakakomba acidification, kuchembera, yellowing brittle uye kunyange comminuted phenomenon.The kudzivirira uye kudzorerwa bepa tsika zvisaririra pamwe bepa sezvo mutakuri kwave akateerera, asi kudzorerwa bepa kubva pamudzi zvishoma, zviri basa rokuchengetedza basa rexies zvakaoma chaizvo rexies basa rokuchengetedza zvakaoma. pane deacidification process, uye zvishoma zvidzidzo zvekusimbisa. Iyo iripo yekusimbisa nzira dzekugadzirisa dzinogona kukonzera kukuvadzwa kwechimiro chepepa, kana kushandura macroscopic morphology yepepa, kana kukurumidza kuchembera kwepepa, uye kuvimba nemanyorero, haigone kuve misa yekusimbisa kugadzirisa.
Zvinoenderana nekuchembera kwemapepa uye zvinhu zvikuru zvinokanganisa kusimba kwebepa, zvakasanganiswa nemamiriro aripo epepa rekuchembera uye zvinodikanwa zvekudzoreredza mapepa etsika zvisaririra, Ultrasonic atomization nzira inoshandiswa kutakura iyo atomized micron giredhi reinforcing agent kusvika mukati mebepa nekumhanya kwakaderera, kuve nechokwadi chekuti bepa racho zvishoma nezvishoma uye zvakazara kudzivirira pepa, kudzora uye kumisa pepa. yekusimbisa kusimba kwekugadzirisa.N-hydroxymethylacrylamide sechinhu chinosimudzira mapepa imonomeri ine mvura yakanaka yekunyungudika uye kemikari reactivity.Kuburikidza necross-linkingkuita pakatiN-Methylol Acrylamide uye mapepa faibha uye ayo ano-crosslinking polymerization zvigadzirwa zvinozadza nzvimbo pakati pemapepa faibha, inovandudza chisungo chesimba pakati pemapepa faibha, uye kuona kusimbiswa kwekugadzirisa kwebepa.
NMAyakashandiswa mukusimbisa kugadzirisa kwe electrostatic copy paper ne ultrasonic atomization method, uye pesvedzero yeatomization absorption, enhancer concentration, atomization rate uye kuomesa tembiricha pakusimbaradza kweelectrostatic copy paper yakaongororwa.Uye shanduko ye macroscopic morphology, microscopic surface structure, surface element content and internal chemical groups of the paper before and after reinforcetion.
Iyo macroscopic morphology yebepa haina kushanduka zvakanyanya mushure mekuvandudzwa kudzoreredzwa, izvo zvakaratidza kutiNMAinogona kubudirira kuona kudzorerwa kwebepa kwakawedzerwa pasina kukonzera kukuvadza kwechipiri, saka inogona kushandiswa kusimbisa kudzorerwa kwemabhuku anokosha ekare akadai sepepa rekuchembera.Mushure mekuchembera kwekugadzira, zvinhu zvemuviri zveN-hydroxymethyl acrylamide pepa rinowedzerwa zviri nani pane izvo zvebepa risina kugadziriswa, kunyanya iyo tensile index uye kubvarura indekisi ine zvakanyanya kugadzikana maitiro e hydrogen uye tsvakurudzo ye hydrogen peak infrared yakagadzikana mukukwegura kwepepa rakasimbiswa rakagadziriswa. Kuwedzerwa kweNMA kunodzivirira chisungo pakati pemapepa fiber kune imwe nhanho.
