Sezvinozivikanwa kune vese, silk screen printing muchina ndiyo midziyo mikuru yebhizinesi rekudhinda rinofanira kushandisa, ikozvino musika wawedzera kukura, vasingakwanise kuvimbisa mhando yekudhinda, silk screen printing muchina kana tichida kuvimbisa kudhinda. mhando yezvinhu zvekudhindisa uye zvishongedzo zvekudhindisa kuita sarudzo yakanaka, saka ungaite sei kuti uve nechokwadi chedhinda yakanaka yemhando yekudhindisa skrini?
Screen printing machine
1, skrini yekumisikidza
Zvigadzirwa zvekugadzirisa zvinoshandiswa mufekitari iyi zvinosanganisira simbi, huni, plywood uye yakajeka PVC mapepa.Kana zvakaoma kuwana, substrate saizi uye diki, iwe unofanirwa kusarudza simbi yekugadzira simbi.Kana zvinyorwa uye zvinyorwa zviri pedyo nekumucheto kwe substrate, zvinofanirwa kugadziriswa padivi pe substrate uye substrate edge sehuni hwepamusoro, kuitira kuti udzivise kunama zvinyorwa uye zvinyorwa.Iyo mambure kureba kazhinji 1.0 ~ 2.5mm.Kana iyo patani yekudhinda iri nyore kunamira kana paine mesh, inofanirwa kugadzirisa chinhambwe chescreen.
2, kusarudzwa kwekrini
Hunhu hwemucheka wesilika hwakagadzikana neunifomu yesilika dhayamita uye yakarurama mesh nhamba.Kazhinji yakasarudzwa mesh ndeye 450 ~ 500 mesh.Mutsara wakanaka, inki yakanaka, kunyura kweiyo substrate, iwe unofanirwa kusarudza yakakwira mesh nhamba chidzitiro, pane zvinopesana, iwe unofanirwa kusarudza yakaderera mesh nhamba chidzitiro.
Plate-kugadzira magiraidhi uye zvinyorwa pachiratidziri uye saizi yechidzitiro zvinofanirwa kunge zvichibva pane substrate chimiro, saizi uye substrate mifananidzo uye zvinyorwa pane iyo nzvimbo.Kana iyo dhizaini isiri yakanaka, ichakanganisa kunaka kwekudhinda skrini, kunyangwe haigone kudhinda skrini.Mukuwedzera, mufananidzo wakafanana uye zvinyorwa pakudhinda, zvakanakisisa kushandisa chinyorwa chekudhinda.Kana yakakamurwa kuita maviri kudhinda dhizaini, maitiro acho anoderedza chiyero chakakodzera chekudhinda skrini.
3, blade kusarudzwa
Zvizhinji zvezvinhu zvinoshandiswa ndeye polyurethane.Polyurethane rubber blade ine yakanaka abrasion resistance, solvent resistance uye kusimba.Iyo yakaoma ndeye 60 ~ 80 shaw.Screen tension, flat flatness ye substrate, unofanira kusarudza high hardness scraper.Pane zvinopesana, inofanira kusarudza yakaderera kuoma.Munzvimbo yakakomberedzwa, yakaderera dhigirii yepasi yakatsetseka kana kuti yakati sandara (yenzvimbo yakakomberedzwa) substrate kudhinda, hupamhi hwekukwesha hunofanira kutetepa kwete kupamhama.
4. Screen printing process
Yakakwira kukwenya kudzvanywa, huwandu hweinki, asi iyo skrini iri nyore kugadzirisa, saka iyo yekukwenya kudzvanywa haifanire kunge yakakwira.Kukwenya kumhanya kunowanzo 60 ~ 200mm / s.Kurumidza kukwenya, ingi shoma, asi hazvisi nyore kuvhara mambure.Naizvozvo zviri nyore kuvharira inki, kukwenya kumhanya kunofanira kukurumidza.Kukwenya mutsara wekuti wakatwasuka, oblique uye curve matatu.Zvinofanira kunge zvichibva pane iyo substrate flatness uye zvinyorwa pane substrate kugovera kusarudza.Kukwesha mutsara kureba uye kushandiswa kweinki, kukwenya ingi kunofanirwa kunge kuri kukwenya dhizaini yeinki, mushure mekukwesha.
5, kugadzirira inki
Iyo dhigirii yekumisikidza nzira yekumisikidza: dhigirii rekuisa inki kuburikidza nechidzitiro, nzvimbo yekudhinda hairatidzike skrini kana waya yekudhirowa.Dhigirii rakatetepa kuisa pachiratidziro, inki ine huremu hwayo inogona kusvikwa kuburikidza nemambure asi kwete kudonhedza zvakanakisa.Kana mitsara yekudhinda yakaonda, inofanira kuderedzwa, kana zvisina kudaro, inofanira kunge yakakora.
Izvo zviri pamusoro apa kuti ungave sei nechokwadi chemhando yekudhinda yekrini yesumo pano, chinyorwa chekudhinda mhando inosanganisira kugadzirira inki, kusarudzwa kwekrini, scraper kusarudzwa, kuisa skrini, kudhinda kwekrini.
