(Zomwe zili pamwambazi ndi zongotengera)
Zindikirani:

*1: Stouffer 21 Stage Exposure Energy Scale.
* 2 × 2.0: Chithunzi chokhala ndi nthawi yanthawi yayitali yojambula kawiri.
* 3: Ngati muyang'ane pa Kudalirika kwa Tending, tikulimbikitsidwa kugwiritsa ntchito mphamvu yowonekera ya 7 ~ 8 siteji.
* 4: Zomwe zili pamwambapa zimayesedwa ndi zida zathu ndi zida zathu.

Ntchito Njira

Chenjezo Mu Kugwiritsa Ntchito

(1) Kugwiritsa Ntchito : Gwiritsani ntchito filimuyi ngati kukana zinthu zosindikizidwa zokhudzana ndi bolodi ndi mapangidwe ena.
(2) Pretreatment : Zotsalira za organic, madontho chifukwa chosakwanira kuthirira ndi kuyanika pamtunda wamkuwa, zingayambitse polymerization ya kukana ndi kulowa kwa plating kapena etching solution.Chonde ziumeni kwathunthu mutatha kutsuka madzi. Makamaka, chinyezi chikakhala mkati mwa dzenje, chihema chimasweka.
(3) Kutentha kwa gawo lapansi : Kutentha kutentha kwambiri kwa nthawi yayitali kungayambitse dzimbiri. Ziyenera kuchitika kwa mphindi zosachepera 10 pa 80 ℃ ndi zosakwana 3 min pa 150 ℃. Ndipo kutentha kwa gawo lapansi kusanachitike kupitilira 70 ℃, makulidwe a filimu pamphepete mwa dzenje amatha kukhala ochepa kwambiri ndipo angayambitse kusweka kwa mahema.
+ Nthawi yokwanira yogwira motsatira (pansi pa nyali yachikasu) ndi masiku 4. Kuwonekera kuyenera kuchitidwa mkati mwa masiku 4 pambuyo pa lamination. Kukula kuyenera kuchitika mkati mwa masiku atatu mutatha kuwonekera. Kuwala kwa nyali yoyera yopanda ultraviolet kumakhala ndi kuwala kwa ultraviolet, kotero gwirani ndi chishango chowala ndi pepala lakuda pansi pake.Sungani kutentha kwa 23±2℃ ndi chinyezi chachibale 60±10%RH. Magawo a laminated ayenera kuyikidwa mu rack imodzi ndi imodzi.
(5) Chitukuko: Pamene kutentha kwa wopanga kupitilira 35 ℃, kungapangitse mbiri yokana kuipitsitsa.
(6) Kuvula: Kuvula pasanathe sabata imodzi kuchokera pamene lamination.
(7) Kuchiza zinyalala : Zowuma filimu zigawo mu mapulogalamu ndi stripper akhoza coagulated ndi neutralization. Zigawo za coagulated zimatha kupatulidwa ndi njira yamadzimadzi pogwiritsa ntchito fyuluta yosindikizira ndi njira ya centrifugal. Njira yolekanitsa yamadzimadzi imakhala ndi ma COD ndi BOD, kotero iyenera kutayira zinyalala m'njira yoyenera.
(8) Mtundu wa kanema : Mtundu ndi wobiriwira/buluu. Ngakhale mtunduwo ungasinthe pang'onopang'ono pakapita nthawi, suyenera kukhudza mawonekedwe.

Chenjezo Pa Kusungirako

(1) Kusungirako kuchitidwa pamalo amdima, ozizira, ndi owuma pa kutentha kwa 5 ° 20 ℃ ndi chinyezi cha 60% RH kapena kutsika, filimu yowuma iyenera kugwiritsidwa ntchito mkati mwa masiku 50 mutapanga.
(2) Sungani mipukutu ya filimu yopingasa pogwiritsa ntchito ma rack kapena matabwa othandizira posungira. Akayalidwa molunjika, mapepala owuma amatha kutsetsereka imodzi ndi imodzi ndipo mawonekedwe ozungulira amatha kukhala ngati mphukira yansungwi (mipukutu imayalidwa chopingasa mu phukusi).
(3) Chotsani mipukutu ya filimu papepala lakuda pansi pa nyali yachikasu kapena nyali yamtundu womwewo. Musawasiye pansi pa nyali yachikasu kwa nthawi yaitali. Phimbani ma rolls a filimu ndi pepala lakuda mukawasunga kwa nthawi yayitali.
