Nws yog tseeb hais tias humidification tsis yog tsuas yog tsim nyog nyob rau hauv lub caij nplooj zeeg thiab lub caij ntuj no.
Yog tias koj lub tuam txhab tsis tau nruab nrog lub ntsuas cua sov-hygrometer, koj yuav tsum tseem xav txog kev ua kom cov av noo thaum twg los yog cov xwm txheej hauv qab no tshwm sim thaum tsim khoom:
1. Thaum cov teeb meem tseem ceeb ntawm kev tsim khoom lossis cov khoom tsis zoo tshwm sim
Qhov no yog qhov qhia ncaj qha tshaj plaws. Yog tias lub rooj cob qhia pom cov teeb meem hauv qab no, nws muaj peev xwm ua rau cov av qis dhau:
Teeb meem hluav taws xob tsis tu ncua (qhov teeb meem pom tseeb tshaj plaws):
· Khoom siv adhesion:Cov ntawv luam tawm (xws li ntawv, PP, flex banner) lo ua ke, ua rau muaj teeb meem pub mis, ntau nplooj ntawv ib zaug, lossis ntawv jams.
· Plua plav attraction:Kev luam ntawv xov xwm saum npoo yooj yim nyiam cov plua plav thiab cov plaub hau los ntawm huab cua, ua rau cov pob dawb los yog qhov tsis xws luag ntawm qhov kawg luam tawm.
· Tus neeg ua haujlwm shocks:Cov neeg ua haujlwm feem ntau xav tias electrostatic tawm thaum ua haujlwm.
· Ink misfiring:Cov duab luam tawm qhia pom dab, qhov muag plooj, lossis tus cwj mem tawg vim muaj kev cuam tshuam zoo li qub nrog tus cwj mem droplet trajectory.
Abnormal ink drying:
A. Kev ziab sai heev (rau cov dej-raws li inks):Ink dries ua ntej tag nrho leveling thiab absorbing, ua rau:
· Muaj kev pheej hmoo ntawm nozzle clogging vim number case qhuav ntawm lub taub hau printhead.
· Xim hloov raws li pigments concentrate, ua rau tsaus nti los yog tsis raug tones.
· Misfiring los ntawm qhuav residue ntawm lub nozzle ntug altering ink drop direction.
B. Qhuav qeeb heev (rau UV inks ntawm tsis yog-absorbent substrates):Txawm hais tias UV inks kho nrog ultraviolet lub teeb, cov av noo ntau dhau tuaj yeem txo tus number case leveling ua ntej kho. Conversely, overly high humidity yuav ua rau condensation ntawm substrates, weakening adhesion.
Khoom deformation:
· Feem ntau yog ntawv-raws li xov xwm:Nyob rau hauv ib puag ncig qhuav heev, daim ntawv poob noo noo, shrinks, los yog curls, ua rau:
· Teeb meem kev sau npe:Kev sib xyaw xim tsis raug thaum lub sijhawm ntau- dhau lossis ntau- xim luam ntawv.
· Wrinkling:Cov xov xwm tsis sib xws tuaj yeem khawb lub taub hau lossis ua rau wrinkles, ua rau lub taub hau puas thiab luam tawm tsis xws luag.
2. Kev tiv thaiv humidification tsav los ntawm ib puag ncig
Kev tswj cov av noo ua ntej muaj teeb meem tshwm sim yog ib txoj hauv kev tswj kom zoo dua. Humidification yuav tsum tau xav txog hauv cov xwm txheej hauv qab no:
Lub caij ntuj qhuav qhuav:
· Lub caij nplooj zeeg thiab lub caij ntuj no, tshwj xeeb tshaj yog nyob rau sab qaum teb, huab cua noo tsawg. Cov cua sov hauv tsev nce qhov kub thiab txias tab sis txo qis cov av noo (qee zaum qis dua 20%).
Cov cua txias tsis tu ncua:
· Cov tshuab cua txias feem ntau dehumidify thaum txias, ua kom cov av noo txaus. Lub 24/7 HVAC system yuav tsum muaj xws li humidification module.
Geographic climate conditions:
· Kev cob qhia hauv thaj chaw qhuav dej (piv txwv li, Beijing, Xi'an, Urumqi) yuav tsum muaj xyoo -them av noo ntau dua li thaj tsam ntawm ntug dej hiav txwv (xws li Shanghai, Guangzhou).
3. Humidification yuav tsum tau los ntawm cov txheej txheem ntau lawm
Qee qhov xwm txheej ntau lawm muaj cov av noo nruj:
Thaum siv static -sensitive substrates:
· Xws li PET, PE, PVC zaj duab xis, ntawv zoo nkauj, lossis ntawv hluavtaws. Cov ntaub ntawv no ua kom zoo li qub tau yooj yim thiab xav tau cov av noo siab dua (50% -60%) txhawm rau tiv thaiv cov khoom zoo li qub.
Thaum lub sij hawm siab -precision printing:
· Rau kev tsim cov duab zoo nkauj, hwm cov duab luam tawm, lossis pov thawj, qhov xim sib xws thiab cov ntsiab lus meej yog qhov tseem ceeb, qhov av noo ruaj khov yog qhov tseem ceeb.
Thaum siv cov cwj mem tshwj xeeb:
· Cov dej -raws li inks:Feem ntau rhiab heev rau cov av noo; yuav tsum tau humidification los tiv thaiv nozzle qhuav.
· Latex inks:Lawv txoj kev kho muaj cua sov thiab qhov cua, uas tuaj yeem ua rau ib puag ncig qhuav, yog li kev tswj hwm av kuj tseem ceeb.
Tswv yim:
Muab koj lub tshuab luam ntawv inkjet nrog lub ntsuas kub kom raug-hygrometer thiab suav nrog hauv kev tshuaj xyuas txhua hnub. Kev tswj hwm ib puag ncig hauv qhov zoo tshaj plaws20 ° -25 ° C thiab 40% -60% txheeb ze humidityyuav txo qis cov teeb meem tsim khoom los ntawm ib puag ncig thiab ua kom zoo ib yam, siab - cov txiaj ntsig luam ntawv zoo.
