Kugadzira Maitiro eRedispersible Polymer Powder

Maitiro ekugadzira redispersible polymer poda (RPP) anosanganisira akati wandei matanho, anosanganisira polymerization, kupfapfaidza kuomesa, uye post-kugadzirisa.Heino mhedziso yeyakajairika maitiro ekugadzira:

1. Polymerization:

Maitiro acho anotanga ne polymerization yemamonomers kugadzira yakagadzikana yepolymer dispersion kana emulsion.Sarudzo yemamonomers inotsamira pane inodiwa zvivakwa uye mashandisirwo eRPP.Manomers akajairika anosanganisira vinyl acetate, ethylene, butyl acrylate, uye methyl methacrylate.

1. Kugadzirira kweMonomer: Monomers inocheneswa uye yakasanganiswa nemvura, ekutanga, uye zvimwe zvinowedzera mumudziyo we reactor.
2. Polymerization: Musanganiswa wemonomeri unopinda mupolymerization pasi pekudzora tembiricha, kudzvanywa, uye kusagadzikana mamiriro.Initiators vanotanga iyo polymerization reaction, inotungamira mukuumbwa kwepolymer cheni.
3. Kudzikamisa: Masurfactants kana emulsifiers anowedzerwa kudzikamisa kupararira kwepolymer uye kudzivirira kusangana kana kuungana kwepolymer particles.

2. Kupfapfaidza Kuomesa:

Mushure me polymerization, iyo polymer dispersion inoiswa pasi pekupfapfaidza kuomeswa kuti ishanduke kuita yakaoma fomu yehupfu.Kupfapfaidza kuomesa kunosanganisira atomizing kupararira kuita madonhwe akanaka, anozoomeswa mumhepo inopisa.

1. Atomization: Iyo polymer dispersion inopombwa kune yakapfapfaidza nozzle, kwainoiswa atomi kuita madonhwe madiki uchishandisa mweya wakadzvanywa kana centrifugal atomizer.
2. Kuomesa: Madonhwe anopinzwa mukamuri yekuomesa, maanosangana nemhepo inopisa (inowanzo kudziya kusvika pakati pe150 ° C kusvika 250 ° C).Kukurumidza kubuda kwemvura kubva mumadonhwe kunotungamirira pakuumbwa kwezvikamu zvakasimba.
3. Particle Kuunganidza: Zvimedu zvakaomeswa zvinounganidzwa kubva mukamuri yekuomesa uchishandisa madutu kana mabhegi mafirita.Fine particles anogona kuenderera mberi nechikamu kuti abvise oversized particles uye kuve nechokwadi chekugovera saizi yakafanana.

3. Post-Processing:

Mushure mekupfapfaidza kuomeswa, iyo RPP inopinda mushure mekugadzirisa matanho ekuvandudza zvimiro zvayo uye kuve nechokwadi chekugadzikana kwechigadzirwa.

1. Kutonhodza: ​​Iyo yakaomeswa RPP inotonhodzwa kusvika kukamuri tembiricha kudzivirira kunyura kwehunyoro uye kuve nechokwadi chekugadzikana kwechigadzirwa.
2. Packaging: Iyo yakatonhodzwa RPP inoiswa mumabhegi anodzivirira hunyoro kana midziyo kuti idzivirire kubva pakunyorova uye hunyoro.
3. Kudzora Hunhu: Iyo RPP inoedzwa yemhando yekudzora kuti ione iyo yemuviri uye makemikari zvimiro, zvinosanganisira particle saizi, kuwanda kwehuwandu, yakasara mwando yemukati, uye polymer zvemukati.
4. Kuchengetedza: Iyo RPP yakaputirwa inochengetwa munzvimbo inodzorwa kuchengetedza kugadzikana kwayo uye hupenyu hwesherufu kudzamara yatumirwa kune vatengi.

Mhedziso:

Maitiro ekugadzira redispersible polymer poda anosanganisira polymerization yemamonomers kugadzira polymer dispersion, inoteverwa nekupfapfaidza kuomesa kushandura kupararira kuita yakaoma fomu yehupfu.Matanho emashure ekugadzirisa anovimbisa kunaka kwechigadzirwa, kugadzikana, uye kurongedza kuchengetedza uye kugovera.Iyi nzira inogonesa kugadzirwa kweakawanda uye anoshanda akawanda maRPP anoshandiswa mumaindasitiri akasiyana, anosanganisira kuvaka, pendi uye machira, anonamira, uye machira.
