Imiqathango yenkqubo yokushicilela i-varnish yoshicilelo lwe-UV
Umphezulu we-uv printing material wamkela umgaqo wokushicilela we-inkjet ye-piezoelectric. I-inki ye-uv itshizwe ngokuthe ngqo kumphezulu wezinto kwaye iphiliswe kukukhanya kwe-ultraviolet ekhutshwa yi-UV-LED. Nangona kunjalo, kwinkqubo yokuvelisa yoshicilelo lwemihla ngemihla, ngenxa yokuba ezinye izixhobo Umphezulu ugudileyo, kunye ne-glaze, okanye indawo yesicelo ifuna kakhulu, kuyimfuneko ukusebenzisa i-coating okanye inkqubo yokunyanga i-varnish ukufezekisa ukumelana nokushisa okuphezulu, ukungangeni kwamanzi, ukuxhathisa ukukhuhla kunye nokunye. iimpawu.
Ke ngawaphi amanyathelo okhuseleko lwenkqubo yokugquma ivarnish yoshicilelo lwe-uv?
1. I-coating isetyenziselwa ukuphucula ukunamathela kwe-inki ye-uv. Ii-inks ze-uv ezahlukeneyo zisebenzisa ii-coatings ezahlukeneyo, kunye nezixhobo ezahlukeneyo zokuprinta zisebenzisa iingubo ezahlukeneyo. Ukuba awuyazi indlela yokukhetha isambatho esifanelekileyo, Ungaqhagamshelana nomvelisi womshicileli we-uv flatbed.
2. I-varnish ifafazwe kumphezulu wepateni emva kokushicilela iphethini. Ngakolunye uhlangothi, ibonisa umphumo obalaseleyo, kwaye ngakolunye uhlangothi, iphucula ukuchasana kwemozulu kwaye iphinda kabini ixesha lokugcinwa kwepatheni.
3. Ukwahlula kuhlulwe kwi-coating-drying coating kunye ne-baking coating. Eyangaphambili idinga kuphela ukusulwa ngokuthe ngqo ukuprinta iphethini, kwaye oku kugqibela kufuneka kufakwe kwi-oven yokubhaka, uze uyikhuphe kwaye uprinte iphethini. Inkqubo kufuneka ilandelwe ngokungqongqo, ngaphandle koko umphumo wengubo awuyi kubonakaliswa.
4. Kukho iindlela ezimbini zokusebenzisa i-varnish, enye kukusebenzisa umpu wombane wokutshiza, ofanelekileyo kwiimveliso ezincinci zebhetshi. Enye kukusebenzisa i-curtain coater, efanelekileyo kwimveliso yobuninzi. Zombini ezi zisetyenziswa emva koshicilelo lwe-uv umphezulu.
5. Xa i-varnish ifafazwe ebusweni be-ink ye-UV ukwenza ipateni, i-dissolution, i-blistering, i-peelling, njl.
6. Ixesha lokugcinwa kwengubo kunye ne-varnish ngokuqhelekileyo i-1 unyaka. Ukuba uvula ibhotile, nceda uyisebenzise ngenkuthalo. Ngaphandle koko, emva kokuvula ibhotile, iya kuhlahloka ukuba ayivalwanga ixesha elide kwaye ayiyi kusetyenziswa.
