Iri bepa rinotarisa pane zvakapetwa kaviri zvinonyungudutsa-isina laminating adhesives, kukurukura kuenzanisa midziyo yezvinonyungudutsa-isina zvigadzirwa.
1. Basic Meaning yeKuenzana Kwepfuma
Leveling pfuma kugona kwejasi kuenzana zvakaenzana uye zvakanaka pamusoro pema substrates.
2. Hukama uye Mhedzisiro yeKukwirisa paMatanho Akasiyana
Muhurukuro inotevera, zvinhu zvekugadzira zvigadziriswe kune zvakafanana, kusanganisira kuvhara uremu, tembiricha, kudzvanywa, nezvimwe. Nekuti zvese zvinhu zvinokonzeresa shanduko kune yekupedzisira laminates, isu tichaona izvi zvinoshanduka seyakagadziriswa.
Nekuti chinonyungudutsa-chisina chinonamira chine chinonyungudutsa kuti chive hwaro, iyo yekuyera pfuma kuita kwenamira kwayo.Zvichienderana nekutaura, ichave yakachena, asi inonamira-isina solvent ichine hunhu hwayo.
Chekutanga, kuyera chivakwa cheSF chinonamira chine hukama hwepedyo ne viscosity yekunamatira pachayo.Nepo viscosity ine hukama hwakananga nekudziya uye inosiyana inversely, zvinoreva kuti viscosity yeSF adhesive inoderera kana tembiricha yawedzera.Zvino pasi petembiricha yekamuri, maviscosities eakasvibira eSF anonamatira ane mutsauko wakakura zvinoenderana neakasiyana eSF anonamatira modhi uye yemuviri zvimiro.Nekudaro, pasi pekushanda kwakakodzera tembiricha yeimwe SF yekunamatira modhi, mutsauko wemhando yeviscosity yayo haisi pachena.Nekudaro, yakaderera viscosity chigadzirwa pamwe isiri iyo iri nani kana uchienzanisa imwe yakakwirira viscosity SF yekunamatira modhi ine yakaderera viscosity imwe.Semuenzaniso, WD8262A/B yeKANGDA NEW MATERIALS, pasi pekushanda kwayo tembiricha (yakatenderedza 45℃), viscosity yayo i1100 mpa.s.Asi kana laminating PET.INK/ALU, anogona kuwana yakanaka chitarisiko pasina dots panguva yokutanga lamination.Sekupedzisa, hazvireve kuti yakaderera viscosity inogona kuunza kutaridzika kwakanaka.Dynamic shanduko yeSF adhesives inguva yekukurumidza, inoda zvinhu zvakati wandei kuti isvike pakuita zvakanaka.Zvichakadaro, viscosity ine yakaderera pasi.Semuenzaniso, pasi pe80-90 ℃ (Double component SF adhesive), viscosity ine shanduko shoma nekukwira kwekushisa.
Frist leveling ndiko kuenderera kwemuviri kwemusanganiswa wekunamira chimiro.Mushure mekuputira, chivakwa chayo chekuyera chinodzikira pamwe nekukurumidza kuita pakati pezvikamu zveA&B uye kudonha kwekushisa.Kazhinji, kuyera kwekutanga kweSF adhesive kunoonekwa sekuyeresa mushure mekucheka mhepo.Panguva ino viscosity yekunamira ichave yakakura kupfuura yakasanganiswa adhesive pane metering rollers.
Kutsetseka kwenamira mbishi zvinoreva kuenzana kwezvinonamira mumadhiramu zvisati zvasanganiswa.Ichi chivakwa chekuenzanisa hachitore chikamu mukugadzirisa kwemafirimu kana foil.
Chechipiri chekuenzanisa chivakwa ndechekuti, mushure mekuita laminating uye mune yekurapa nhanho, iyo SF inonamira inopinda munhanho yekukurumidza kuyambuka-link reaction pasi pesimba rekushisa, uye kuita kwemazinga kunoderera kusvika kunyangarika zvachose.
3. Mhedziso
Kukwirisa chivakwa chembishi SF chinonamira chisati chasanganiswa> chechipiri chekuyera chivakwa> kuyera chivakwa cheakasanganiswa SF chinonamira pane metering rollers> yekutanga kuyera chivakwa.Naizvozvo, viscosity shanduko yemaitiro eSF adhesives idanho rinosimuka, iro riri pachena rakasiyana neSB adhesives.
Kana iwe uine chero mibvunzo nezve SF laminating yekuchinjika kurongedza, isu takagadzirira kukubatsira.
