Iyo yekuputira firimu kuumbwa kwemavara akavharwa ndiro inonyanya kusanganisira kunamatira adhesion uye kuomeswa nekuomesa.
A Ruvara yakavharwa ndiro inobatisa adhesion
Nhanho yekutanga yekunamatira kwesimbi strip substrate uye kupfekedza ndiko kunyorova kwemavara akaputirwa ndiro yakashongedzwa pamusoro peiyo substrate.Kunyorova kwekuputira kunogona kutsiva mhepo nemvura pakutanga yakashambadzirwa pamusoro peiyo simbi strip substrate.Panguva imwecheteyo, kuvhuvhuta kweiyo solvent pamusoro peiyo substrate ine mhedzisiro yekuparara kana kuzvimba.Kana iyo solubility parameters yefirimu inogadzira resin yeruvara yakavharwa ndiro yekuputira uye pamusoro peiyo substrate yakasarudzwa nemazvo, iyo yakasanganiswa-yakasanganiswa layer ichaumbwa pakati pepamusoro peiyo ruvara yakavharwa ndiro substrate uye firimu rekuvhara, Izvi zvakanyanya. zvakakosha pakunamatira kwakanaka kwekuputira.
B Ruvara rwakavharwa ndiro yekubatisa kuomesa
Iko kunamatira kuvakwa kwemavara akaputirwa ndiro inongopedza nhanho yekutanga yekuputira firimu kuumbwa mune yekubikira yejira rakavharwa ndiro, uye zvakare inoenderera mberi neiyo nzira yekushandurwa kuita yakasimba inoenderera firimu, iyo inogona kupedzisa iyo yekuputira firimu kuumbwa. process.Iyi nzira kubva ku "wet film" kusvika "dry film" inowanzonzi "kuomesa" kana "kuporesa".Uku kuomesa uye kurapa maitiro ndiwo musimboti wekuputira firimu kuumba maitiro.Mhando dzakasiyana-siyana uye zvinyorwa zvekuputira zvine maitiro avo ekugadzira firimu, iyo inotarirwa nehupfumi hwezvinhu zvekugadzira firimu zvinoshandiswa mukuputira.Kazhinji, tinokamura firimu-kuumba yejasi muzvikamu zviviri: yakasimba uye munda
(1) Kusashandurwa.Kazhinji, inoreva nzira yekugadzira firimu yemuviri, iyo inonyanya kuenderana nekuputika kwezvinonyungudutsa kana zvimwe zvinoparadzira media mufirimu, uye viscosity yefirimu inowedzera zvishoma nezvishoma kuita firimu rakasimba.Semuenzaniso: acrylic pendi, chlorinated rabha pendi, vinyl pendi, nezvimwe.
(2) Kuchinja.Kazhinji, inoreva maitiro emakemikari anoitika panguva yekugadzira firimu, uye kuumbwa kwefirimu rejasi kunoenderana nekuita kwemakemikari.Rudzi urwu rwekugadzira firimu ndiyo hurongwa hwezvinhu zvekugadzira firimu mune coating polymerizing iyo firimu inonzi polymer mushure mekuvakwa.Zvinogona kunzi inzira yakakosha yepolymer synthesis, iyo inoteedzera zvakazara maitiro ekuita kwepolymer synthesis.Semuenzaniso: alkyd coating, epoxy coating, polyurethane coating, phenolic coating, etc. Zvisinei, zvipfeko zvakawanda zvemazuva ano hazvigadziri mafirimu nenzira imwe chete, asi kuvimba nenzira dzakawanda dzekugadzira mafirimu.Iyo coil coil ndeye yakajairika iyo inovimba nenzira dzakawanda dzekugadzira mafirimu.
