Gutpela wok bilong rotogravure printing long kamapim gutpela, bikpela volium, na wankain piksa kwaliti i mekim em i stap aut long ol narapela wok bilong 'packaging' na pablikesen printing. Tasol, 'surface treatment-em i wanpela bikpela samting tasol planti taim ol i no save tingim pastaim long -press-em i bikpela samting long kamapim dispela gutpela risal.
Bikpela wok bilong tritim pes long 'gravure printing'
Wok bilong kisim ink long ol liklik sel we ol i bin katim insait long wanpela silinda i go antap long wanpela samting ol i kolim rotogravure printing, o gravure. Eneji bilong samting we ol i prinim i gat bikpela impak long wok bilong dispela trensfe. Planti bilong ol 'flexible packaging materials', olsem 'polyethylene' (PE), 'polypropylene' (OPP, BOPP), na 'polyester' (PET), ol i no inap long kisim wara na 'oleophobic' bikos ol i no gat planti strong long en. Dispela i save kamapim planti hevi long kwaliti, olsem ink i no save wet gut na i no save pas gut.
Sapos ol i no redim gut ol samting bilong printa, dispela i save putim ol printa long kisim bikpela 'rejection rates', ol i save kisim dilei long wokim ol samting, na ol i no save stap longpela taim moa. Wanpela gutpela 'surface treatment' bilong 'gravure printing' i save senisim 'surface' bilong 'substrate' long 'molecular level', na dispela i save strongim strong bilong en na i save helpim wok bilong putim ol ink, 'varnish', na 'adhesive' longpela taim.
Ol hevi bilong 'gravure printing' we i save kamap wantaim 'surface energy'
Koting i no wok gut na ink i no pas gut
Ink we i save skrapim, bruk bruk, o bruk hariap em i nambawan mak bilong soim olsem ol i no redim gut pes bilong en. Antap long bagarapim lukluk bilong en, dispela hevi bilong ink long pas gut long 'gravure printing' i ken bagarapim ol samting we i pasim ol kaikai o medikel paket, na dispela i ken kamapim hevi long sefti bilong prodak na risponsibiliti bilong bren.
Ol hap we i no gat wara na ink i save rausim
Ink i no stap stret, ink i wok long go antap bikos i no gat planti pawa long en. Moa yet long ol hap we i gat ol strongpela kala, dispela i save kamap olsem 'pinholing', 'retraction', o 'print density' i no wankain. Em i bagarapim gutnem bilong gravure long kamapim gutpela piksa.
Hevi wantaim Kontaminesen na Konsistensi
Ol samting nogut we yumi no inap lukim long taim bilong wokim na holim, olsem ol samting bilong rausim ol samting, oil, o das, i ken stap insait long ol samting i stap aninit long graun. Ol dispela i save pasim wok bilong tritmen. Na tu, long taim bilong 'longgravure printing' teknik, ol samting we i no wankain insait long wanpela rol o namel long ol 'batch' i save kamapim ol samting we i no wankain long kwaliti bilong prinim.
Ol hevi wantaim Statik Elektrisiti na Web Prosesing
Planti ol 'polymer film' i save kamapim 'static charge', we i save pulim das, na dispela i save kamapim hevi long 'web handling' olsem 'misfeeds', na tu em inap long kamapim hevi long ol 'solvent-based gravure settings. Maski em i wanpela hevi bilong lektrik, ol wok bilong stretim graun i save gat dispela hevi.
Katim -Ol rot bilong stretim arere bilong 'Contemporary Gravure Printing'
Indastri i yusim ol teknoloji we ol i bin testim na divelopim we i save givim strongpela, gutpela 'substrate activation' long stretim ol dispela hevi we i save kamap planti taim long ol wok bilong 'gravure'.
Tritmen bilong Corona na Plasma: Ol Standet Bilong Indastri
Nambawan teknik bilong strongim ink long pas gut long 'gravure printing' em i 'corona discharge treatment'. Em i save putim sabstret long wanpela hai-voltej, hai-frikwensi pawa taim em i putim antap long wanpela rola we i gat graun. Dispela i save apim strong bilong dispela samting na strongim pasin bilong pas long en long rot bilong mekim win i stap klostu i kamap 'ionizing' na kamapim wanpela 'plasma' we i save 'oxidise' pes bilong dispela samting.
Ol gutpela samting i stap insait long -lain, ol i soim olsem ol i ken dipen long ol, na ol i wok gut tru long planti ol 'polyolefins'.
Tingim olsem mak bilong tritmen inap long go nogut wantaim taim (shelf-laip) na ating yu mas lukautim gut long stopim ovatritmen, we inap long bagarapim sampela piksa.
Wantaim liklik hat impak, atmosferik plasma tritmen em i wanpela moa sofistiketed solusen we i givim moa stretpela, wankain, na strongpela senis long pes. Em i wok long kamap moa populer long ol 'sensitive substrates' na ol wok we i hat long mekim wok.
Tritmen wantaim paia bilong sampela kain samting
Flame tritmen, we ol i save putim long ol tikpela, tripela-dimensenel kontena o sampela film, i save oksidaisim pes bilong en long yusim wanpela paia bilong ges we i save kukim. Maski ol i no save yusim planti taim long ol liklik piksa insait long web gravure, em i wanpela gutpela tul bilong sampela wok we i gat ol gravure printing pes.
Ol 'coating adhesion promotors' na ol 'chemical primars'
Sampela taim ol i save putim wanpela 'liquid primer' o 'adhesion booster' pastaim long ol i prinim, moa yet wantaim ol 'substrates' we i no gat planti pawa. Wanpela 'responsive intermediate layer' i kamap olsem risal. Taim yumi skelim wantaim ol drai tritmen olsem corona, dispela rot i hat moa, i gat bikpela pe, na i ken kamapim ol 'volatile organic compounds' (VOCs), maski em i wok gut.
Stretim Prosedur: Skelim na Gutpela Teknik
Implementesen bilong teknoloji em i hap bilong pait tasol. Strongpela proses kontrol em i bikpela samting long kisim ol gutpela risal.
Dyne Testing: Bihain stret long tritmen na pastaim long prinim, ol i mas sekim ol 'surface energy' level wantaim ol 'dyne test pen' o ol solusen.
In-lain Monitoring: Long mekim wankain tritmen long olgeta hap bilong web, ol sistem bilong nau i save putim ol 'real-time monita.
Wok bilong lukautim ol samting: Long abrusim re-kontaminesen bilong ol 'activated surfaces', gutpela 'winding', 'storage', na 'cleanness' namel long 'treatment' na 'printing station' em i bikpela samting.
Sastenebiliti na Stretpela wok long Gravure Surface Tritmen long bihain taim
Ol samting bilong stretim ol samting antap long graun i save senis taim bisnis bilong prinim ol piksa i save senis. Ol sistem we i gat bikpela eneji efisiens, liklik ozone prodaksen, na kompatibiliti wantaim ol nupela, sastenebol sabstret-olsem ol mono-material films na ol bio-bes plastik-i wok long kamap moa yet. Na tu, ol i nidim moa stretpela, skel, na wankain tritmen teknoloji, olsem ol 'neks-jeneresen plasma sistem, bikos long wok bilong 'ultra-hai-kwaliti printing na wok bung bilong ol 'functional' na 'conductive' ink.
Pinis bilong tok: Namba wan Step i go long Gravur Ekselens
Long pinisim, olgeta ogenaisesen we i yusim rotogravure printing i mas stretim ol hevi bilong tritmen bilong pes olsem wanpela stratejik nesesiti na i no wanpela teknikel hevi tasol. Ol konveta i ken yusim gut 'gravure' proses long rot bilong putim mani long ol gutpela rot bilong stretim 'surface' na kliagut long ol hevi bilong ink i no pas gut. Dispela i no givim gutpela lukluk tasol, tasol tu strongpela, longpela taim we i holim strong bilong bren na i inapim ol gutpela wok insait long wanpela bikpela indastri. Wanpela stretpela redi pes em i namba wan step i go long gutpela gravure print kwaliti.
