1. Phau ntawv bronzing muab tshuaj txhuam
(1) Phau ntawv tiaj tus bronzing muab tshuaj txhuam: Nws yog cov organic ua ke ntawm acrylic emulsion thiab tackifying resin emulsion copolymerized los ntawm acrylic ester nrog cov khoom tshwj xeeb. Qhov no txhim kho kev sib raug zoo thiab kev ruaj ntseg ntawm emulsion, ua rau kom lub zog tev ntawm emulsion, thiab ua kom cov bronzing muab tshuaj txhuam kom bronzing ntawm qhov kub thiab txias. Yog li ntawd, ntau cov ntaub ntawv raug muag ua ke nrog cov chaw luam ntawv, tseem hu ua txias bronzing paste. Vim tias qhov kub stamping paste tuaj yeem tsim cov nplaum nplaum ntawm qhov kub ntawm 35 ° C ~ 120 ° C, nws yog precisely los ntawm kev noj kom zoo dua ntawm lub zog pib adhesion ntawm resin emulsion nws tus kheej kom xa cov ntawv kub stamping rau kub stamping paste. . Cov yam ntxwv ntawm cov bronzing paste yog: lub bronzing muab tshuaj txhuam yog nyias me me, mos rau qhov kov, elastic, thiab tsis ntsws. Nws yog tshwj xeeb tshaj yog haum rau kab bronzing thiab manufacturers uas nrhiav tes zoo li.
(2) Peb-dimensional bronzing paste: Nws yog cov khoom ntawm acrylic emulsion lossis EVA emulsion grafting tshuab. Qhov loj tshaj plaws ntawm peb-dimensional bronzing paste yog tias cov ntsiab lus khoom muaj siab, thiab yuav tsis muaj pob thaum siv. Siv cov tshuaj ntsuam zoo tib yam (80-120 mesh/im) uas feem ntau yog siv, qhov xav tau zaj duab xis tuab tuaj yeem ua tiav los ntawm ntau yam luam ntawv. Cov nyhuv 3D luam ntawv tau txais, thiab tom qab ntawd qhov kev ua haujlwm siab thiab qhov kub thiab txias ntawm lub tshuab hloov pauv tau hloov kho rau kub stamping los tsim cov nyhuv peb-dimensional kub stamping.
(3) Daim iav bronzing muab tshuaj txhuam: Nws yog ib qho bronzing paste synthesized los ntawm kev ntxiv kub yaj hmoov rau EVA polymer copolymer. Cov tsos ntawm daim iav bronzing muab tshuaj txhuam yog milky dawb, vim hais tias cov bronzing muab tshuaj txhuam muaj ntau cov kub yaj hmoov, thaum luam tawm lub substrate, nws yog ib qho yooj yim mus sau lub uneven nto ntawm lub substrate. , cov nyhuv reflective yog zoo heev, muaj ib daim iav nyhuv. Yog li ntawd, ib txhia neeg hu nws daim iav bronzing paste. Daim iav bronzing muab tshuaj txhuam muaj cov hmoov kub yaj, yog li nyob rau hauv cov txheej txheem ntawm kub nias, bronzing kub nyob ntawm qhov sib tov kub ntawm cov hmoov kub yaj kom ua tau zoo washability; qhov no kuj yog vim li cas vim li cas daim iav bronzing muab tshuaj txhuam xav tias nyuaj dua li lwm cov bronzing pastes.
2. Mechanical printing bronzing paste
(1) Mechanical aircraft printing bronzing paste: Nws txawv ntawm phau ntawv dav hlau bronzing paste. Phau ntawv tiaj tus bronzing muab tshuaj txhuam ua raws li qhov loj ntawm qhov pib adhesion, thaum tshuab luam ntawv bronzing muab tshuaj txhuam yuav tsum muaj qhov me me pib adhesion. Thaum daim ntaub raug mob tom qab daim ntaub luam ntawv, yuav tsum tsis muaj ntaub plaub, txwv tsis pub nws yuav cuam tshuam rau qhov kawg ntawm cov khoom. Cov txheej txheem ntawm bronzing muab tshuaj txhuam rau cov tshuab dav hlau luam ntawv: ntaub sizing → ziab → ntaub sau → daim ntaub tso → bronzing → sib sau. Cov neeg kho tshuab dav hlau bronzing muab tshuaj txhuam muaj qhov zoo vim qhov me me ntawm qhov loj me, tab sis lub bronzing flatness tsis zoo heev thiab qhov ci ntsa iab tsis zoo, yog li qee cov neeg hu nws frosted bronzing.
