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 kwebepa kubva pamudzi zvishoma, zvakaoma kunyatsowedzera hupenyu hwayo hwebasa.Basa riripo rekuchengetedza uye rekudzorera rinonyanya kukoshesa maitiro e deacidification, uye zvidzidzo zvishomanana pakusimbisa. 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 zvinodiwa pakudzoreredza mapepa etsika zvisaririra, Ultrasonic atomization nzira inoshandiswa kutakura iyo atomize micron giredhi inosimbisa mumiriri kuenda. mukati mepepa pamhepo yakaderera zvikuru, kuve nechokwadi kuti pepa racho zvishoma nezvishoma uye zvakakwana kutora mumiririri wekusimbisa, sezvinobvira kudzivirira kuparara kwepepa, uye inogona kushandiswa kugadzirisa hukuru hwekusimbisa.N-hydroxymethylacrylamide se paper enhancer is a monomer ine good solubility yemvura uye chemical reactivity.Through thecross-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 mukusimbaradza kugadzirwa kwepepa re electrostatic copy 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. chimiro, pamusoro pechinhu chemukati uye mapoka emakemikari emukati epepa pamberi uye mushure mekusimbisa.
Iyo macroscopic morphology yebepa haina kuchinja zvakanyanya mushure mekuvandudzwa kudzoreredzwa, izvo zvakaratidza kutiNMAinogona kubudirira kuona kugadziridzwa kudzoreredzwa kwebepa pasina kukonzeresa kukuvadzwa kwechipiri, saka inogona kushandiswa kusimbisa kudzoreredzwa kwemabhuku anokosha ekare akadai sepepa rekuchembera.Mushure mekuchembera, hunhu hweN-hydroxymethyl acrylamide bepa rakakwenenzverwa zviri nani pane izvo zve bepa risina kubatwa, kunyanya iyo tensile index uye kubvarura indekisi ine zvakanyanya kugadzikana kuita; Kuongororwa kweiyo infrared spectrum kunoratidza kuti maitiro epamusoro ehydrogen bond akanyanya kugadzikana mukuchembera kwebepa rakasimbiswa rakagadziriswa. Kuwedzerwa kweNMA kunodzivirira chisungo pakati pemapepa fiber kune imwe nhanho.
