Cov ntsiab lus tseem ceeb rau kev txhim kho plexiglass npo luam ntawv txheej txheem

Mastering zoo plexiglass screen tshuab luam ntawv yog qhov tseem ceeb kev quab yuam kom plexiglass ua cov nroj tsuag. Cov ntsiab lus tseem ceeb rau kev txhim kho ntawm plexiglass npo luam ntawv txheej txheem muaj raws li hauv qab no:

1. Qhov yuav tsum tau ua kom tiav rau kev tsim cov duab zoo meej yog tias qhov zoo ntawm cov pob tshab zoo zaj duab xis yuav tsum yog qhov zoo, uas yog, cov npoo ntawm cov dot yuav tsum zoo nkauj thiab opaque. Cov xim sib cais xim thiab luam ntawv siv tau siv cov xim sib txawv.
   

2. Qhov zoo ntawm daim duab zaj duab xis tau muab tso rau ntawm lub khob ntim nrog plexiglass, thiab mam li nthuav tawm. Qhov ncab ncab tau muab tso rau ntawm qhov zoo ntawm daim duab zaj duab xis, mus tib seem rau daim duab axis. Yog tias cov moire qauv tshwm, tig lub vijtsam mus rau sab laug lossis sab xis kom txog thaum cov qauv moire ploj, feem ntau tig 7 °. Thaj chaw uas cov moire tau yooj yim tsim yog nyob rau hauv cov kev taw qhia ntawm xaim xov hlau thiab kev sib tshuam ntawm cov hlau xov hlau. Cov xim tseem ceeb thiab cov xim tsaus nti ua rau muaj teeb meem ntau ntxiv nrog moire.

3. Rau plaub-xim luam ntawv, aluminium npo ntas ntawm tib qho loj me thiab ruaj khov yuav tsum siv, thiab txhua daim thav duab siv tau yog ncab nrog cov ntxaij vab tshaus ntawm tib hom thiab qauv. Kev siv cov viav vias siv pab kom tshem tawm lub moiré. Lub nro ntawm lub vijtsam yuav tsum zoo ib yam thiab qhov nro ntawm plaub ntxaij ntawm plaub-xim luam ntawv yog tib yam.

4. Lub qhov dej khawb hauv av yog qhov tseem ceeb heev rau kev luam ntawv zoo. Lub Shore hardness ntawm cov hniav yog li 70. Tus squeegee yuav tsum tau teem rau ntawm kaum ntawm 75 °. Yog hais tias lub kaum sab xis ntawm lub rubeegee tau hloov kho ib yam nkaus thiab, daim ntawv luam tawm yuav raug qhov muag plooj. Yog hais tias lub kaum sab xis hloov kho dhau lawm, qhov kev pheej hmoo ntawm kev tshuaj ntsuam-luam tawm duab kev kos duab yog siab.

5. Tus number case-rov rab riam yuav tsum tsis txhob muab ntsia dhau qhov qis. Yog li ntawd, zaj duab xis yuav puv nrog tus number case ntau dhau, thiab cov ntawv luam tawm yuav yooj yim ua rau blurred thiab smudged.

6. Lub vijtsam xim duab luam tawm tau luam tawm nrog cov kua roj-viscosity. Ua haujlwm huv lub vijtsam, tuab cov kua xaum yuav tsum muaj.

7. Thaum siv UV number case, cov xim hue ntawm lub vijtsam duab yuav tsum yog 5% rau 80%, thiab Shore qhov nyuaj ntawm lub qhov taub yuav tsum yog 75. Yuav kom tswj tau UV number case ntawm Tianjin plexiglass kev ua haujlwm tsis muaj smudging thaum xim overprinting, nws yog pom zoo kom luam tawm xim raws ntu ntawm cyan, magenta, daj, thiab xim dub. Thaum siv UV number case, lub vijtsam thickness yuav tsum tsis pub tshaj 5um.
