Zvigadzirwa zvakagadziridzwa zvepolyacrylamide zvinoshandiswa sekuchengetedza uye zviya zvinobatsira mukugadzira mapepa zvinowanzogadziridzwa zvigadzirwa zvepolyacrylamide, zvinosanganisira anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM) uye amphoteric polyacrylamide (AmPAM), ine hama molecular mass inosvika 2 miriyoni ~4 miriyoni. .
Kazhinji, APAM inoumba hurongwa hwakaoma nemamwe cationic makomisheni kuti itambe yakasimba kuchengetedza-yamuro maitiro.Semuenzaniso, kusanganisa nealuminium sulfate kunogona kuita kuti APAM inyatsobatana nefibers, fibres yakanaka, mafirita, nezvimwewo, nekudaro zvakanyanya kunatsiridza kuchengetwa kwefivha yakanaka uye mafiritsi.Attention rate.
CPAM ndeimwe yeanonyanya kushandiswa kuchengetedza anobatsira mukugadzira mapepa, uye zvigadzirwa zvine huremu hwemamorekuru uye low charge density zvinowanzo shandiswa.Kuchaja kwayo kunopesana neiyo fiber, uye inogona kushandiswa yega kana kusanganiswa nebentonite, anion, nezvimwewo, kukonzera flocculation yepepa nenzira yebhiriji muzvinyorwa zvepepa, uye inogona kuwedzera chiyero chekuchengetedza. mapepa ekuzadza uye kukurudzira Kusanganiswa kwemvura yakachena pasi pemambure kunoderedzwa.Kana CPAM uye bentonite inopomerwa zvisina kunaka inoshandiswa kugadzira chidimbu chekuchengetedza uye dhizaini yekubatsira hurongwa, ukuru hwema flocs ezvinyorwa zvemapepa akaumbwa nekuwedzera CPAM yakakura, uye mushure mekuiswa pasi pesimba reshear mushure mekupfuura nepapombi yepulp uye. zvimwe zvigadziriso, zvimedu zvakaputsika kuita zvidimbu zviduku, uye kuwedzerwa kwebentonite yakashata panguva ino ichadzorera zvakare mabhiriji maduku maduku uye kuumba flocs iyo iduku kudarika iyo yakatanga kuumbwa neCPAM.Nokudaro, chiyero chekuchengetedza kwezvinyorwa zvepepa chinovandudzwa, uye kuenzana uye kushanda kwemvura yepepa kunovandudzwa.
Apo AMPAM inoshandiswa sekuchengetedza uye rubatsiro rwemvura, mapoka eanionic anodzinga marara eanionic mu pulp, uye mapoka e cationic anobatanidza nefibers uye fiber yakanaka.Nokudaro, chiyero chekuchengetedza kwefibers yakanaka inovandudzwa zvakanaka.
