Kugadzirwa kwefirimu recolor coated boardmabhanhire anonyanya kusanganisira zvinhu zviviri: coating adhesion uye coating kuomesa.
Kunamatira kweA color coated board coating
Nhanho yekutanga yekunamira pakati pesimbi strip substrate uye yekupfekedza iko kunyorova kweruvara rwakaputirwa bhodhi rukukwe pane substrate pamusoro.The coating wetting inogona kutsiva mhepo uye mvura pakutanga adsorbed pamusoro simbi strip substrate pamusoro.Panguva imwecheteyo, kuvhuvhuta kweiyo solvent pane substrate surface kunotungamirira mukuparara kana kuzvimba.Kana iyo solubility parameters yefirimu-inogadzira resin yeruvara yakavharwa bhodhi coating uye iyo substrate pamusoro yakasarudzwa nenzira kwayo, inoumba immiscible layer pakati peruvara rwakavharwa bhodhi substrate pamusoro uye firimu rekuvhara, Izvi zvakakosha pakunamira kwakanaka kwejasi.
Kuomesa Bcolor coated boardcoating
Iko kunamatira kuvakwa kwemavara akavharidzirwa bhodhi coating inopedza nhanho yekutanga yekuputira firimu kuumbwa mukuita kwekuputira kweruvara rakavharwa bhodhi, uye maitiro ekuva yakasimba inoenderera firimu inoda kuenderera, iyo inogona kupedzisa iyo yose yekuputira firimu yekugadzira maitiro.Maitiro ekuchinja kubva ku "wet film" kuenda ku "dry film" inowanzonzi "kuomesa" kana "kurapa".Uku kuomesa uye kurapa maitiro ndiwo musimboti wekuputira firimu kuumba maitiro.Zvipfeko zvine maitiro akasiyana-siyana uye zvinyorwa zvine maitiro avo ekugadzira mafirimu, ayo anotarirwa nehupfumi hwezvinhu zvekugadzira firimu zvinoshandiswa mukuputira.Kazhinji, isu tinokamura iyo firimu-yekugadzira maitiro ekupfeka muzvikamu zviviri:
(1) Haisi kushandura.Kazhinji, inoreva nzira yekugadzira firimu yemuviri, iyo inonyanya kuvimba nekuputika kwezvinonyungudutsa kana zvimwe zvinoparadzira midhiya mufirimu yekuputira, zvishoma nezvishoma kuwedzera viscosity yefirimu yekuputira uye kugadzira firimu rekuvhara rakasimba.Semuenzaniso, acrylic coatings, chlorinated rubber coatings, ethylene coatings, nezvimwe.
(2) Kuchinja.Kazhinji, inoreva kuitika kwemakemikari maitiro panguva yekugadzira firimu, uye kupfekedza kunonyanya kutsamira pakuita kwemakemikari kugadzira firimu.Iyi firimu-yekugadzira maitiro inoreva polymerization yezvinhu zvekugadzira firimu mumachira, anonzi mapolymers, mushure mekushandisa.Zvinogona kunzi inzira yakakosha yepolymer synthesis, iyo inoteedzera zvakazara maitiro ekuita kwepolymer synthesis.Semuenzaniso, alkyd coatings, epoxy coatings, polyurethane coatings, phenolic coatings, etc. Zvisinei, zvipfeko zvakawanda zvemazuva ano hazvigadziri mafirimu nenzira imwe chete, asi zvinovimba nenzira dzakawanda kuti pakupedzisira dzigadzire mafirimu, uye coil coil imhando yemhando yefirimu inovimba nenzira dzakawanda kuti pakupedzisira iite mafirimu.
