Polyacrylamideizwi rinowanzoreva homopolymers eacrylamide kana copolymers nemamwe mamonomers. Ndiyo imwe yeanonyanya kushandiswa mumvura-soluble polymers. Polyacrylamide iripo muchimiro chewhite granules uye inogona kuiswa mumhando ina: non-ionic, anionic, cationic, uye amphoteric ionic.
Zvishandiso zvePolyacrylamide muPapermaking Field
Iyo yekugadzira mapepa ine matanho akati wandei, anosanganisira pulping, kuongorora, kuchenesa, kunatsa, uye kuumba. Munguva idzi maitiro, kusvibiswa kwakasiyana senge fiber, mafirita, uye faindi zvinogadzirwa. Kana izvi zvisina kuchena zvisina kubviswa zvakanaka kubva muhuputi, zvinogona kutungamirira kumatambudziko akadai semvura yakashata uye simba rakaderera repepa. Polyacrylamide inonyanya kushandiswa se dissperant, kuchengetedza rubatsiro, drainage rubatsiro, flocculant, uye saizi mumiriri mukugadzira mapepa.
Ⅰ. Dispersant
Kuwedzera polyacrylamide dispersant panguva yekugadzira mapepa kunogona kudzivirira zvinobudirira kuunganidzwa kwefiber uye kugadzirisa kufanana kwepepa. Huwandu hwekuwedzera hwakaderera hunogona kusimudzira kupararira kwakanaka kwemafivha ekugadzira mapepa uye kuwana yakanakisa kuumba pepa. Inogonawo kuvandudza kufanana kwe pulp uye kupfava kwepepa, uye kuwedzera simba rezvivakwa zvebepa. Iyo yakakodzera kune akasiyana epamba emba zvigadzirwa zvemapepa senge pepa rechimbuzi, napkins, kumeso matishu, uye mamwe mapepa matete. Mune mamwe mapepa emapepa, anogona kutsiva zvachose Polyethylene Oxide (PEO).
Ⅱ. Retention Aid
PAM inowanzoshandiswa sechibatsiro chekuchengetedza mumhizha yekugadzira mapepa kuti iwedzere fiber retention rate uye kuderedza kubuda kwetsvina. Nheyo yaro yekushanda ndeyekuumba flocs yakakura ine zvidimbu zvidiki, izvo zvinogona kubviswa nyore kubva mupuru kuburikidza nekusefa kana sedimentation.
Ⅲ. Drainage Aid
PAM inogonawo kushanda seyamuro yemvura mukugadzira mapepa. Inowedzera chiyero chemvura, ichigonesa kukurumidza uye nekunyatso bvisa mvura yepepa pamushini wepepa. Izvi zvinobatsira kuwedzera kukurumidza kwekugadzira uye kuderedza kushandiswa kwesimba nekupfupisa nguva yekuomesa inodiwa papepa.
Ⅳ. Sizing Agent
Mune zvimwe zviitiko, polyacrylamide inoshandiswa seye saizi mukugadzira mapepa kudzora kupinda kwemvura uye zvimwe zvinwiwa mubepa rebepa. Izvi zvinobatsira mukuwana zvinhu zvinodiwa senge mvura kuramba uye inki holdout, kunyanya mumashandisirwo apo bepa rinoda kumira munyoro kana kudhinda maitiro.
Ⅴ. Flocculant
Munguva yemvura yetsvina yekurapa mumill yemapepa, polyacrylamide inogona kushandiswa senge flocculant kubvisa yakaturikwa yakaoma uye zvinosvibisa mumvura ine tsvina. Inobatsira kuumba zvidimbu zvakakura zvinonzi flocs, izvo zvinogona kubviswa nyore nyore kuburikidza ne sedimentation kana filtration process. Izvi zvinobatsira kuderedza kusvibiswa kwemvura uye kuvandudza kuchengetedzwa kwezvakatipoteredza kwebhizimisi rekugadzira mapepa.
Pakazere, zvinhu zvakasiyana-siyana zvepolyacrylamide zvinoita kuti ive yekuwedzera yakakosha muindasitiri yekugadzira mapepa, zvichibatsira mukuvandudza kushanda zvakanaka, mhando yechigadzirwa, uye kuita kwezvigadzirwa zvemapepa. Kushandiswa kwepolyacrylamide mumunda wekugadzira mapepa kunobata indasitiri yese yekugadzira mapepa, kubva pakugadzira mapepa kusvika pakuchenesa mvura. Haisi kungovandudza kunaka uye kubudirira kwekugadzirwa kwepepa, inoderedza mari yekugadzira, asiwo inopa rubatsiro rwakanaka mukuchengetedzwa kwezvakatipoteredza.
