Kev Npaj thiab Mesh Stretching
Kev xaiv cov khoom: Xaiv cov polyester mesh raws li tus qauv tsim intricacy; siv 100-150 mesh rau cov qauv luam ntawv, thiab 200 mesh lossis siab dua rau cov kab zoo.
Kev Tswj Kev Nyuaj Siab: Uniformly stretch lub mesh mus rau 18-25 N / cm² (nrog rau kev kam rau siab tsis pub tshaj 1 N / cm²) thiab ruaj ntseg rau ib tug hlau los yog ntoo ncej.
Tshaj tawm - kev ua haujlwm: Tso cai rau nws teem sijhawm 24 teev kom muaj kev ruaj ntseg, txiav tawm cov mesh ntau dhau ntawm sab nraum lub thav duab, thiab ntxuav tawm cov nplaum qub lossis tus cwj mem.
Mesh Degreasing thiab Emulsion Txheej
Degreasing: Rov qab so ob sab ntawm lub mesh nrog lub nruab nrab degreaser kom tshem tawm cov roj thiab hmoov av; Tom qab ntawd, maj mam so nrog lint -dawb daim ntaub thiab cia kom qhuav los txhim kho emulsion adhesion.
Muab ob npaug rau-sided Txheej: Siv cov photosensitive emulsion sib npaug rau ob sab ntawm lub mesh, kom ntseeg tau cov tuab tuab kom tsis txhob muaj txheej tsis sib xws.
Kev ziab khaub ncaws: Muab cov tshuaj pleev xim rau hauv qhov cub kom qhuav thiab qhuav kom huv si ntawm qhov kub ntawm kwv yees li 40 degree; Thaum tshav kub kub heev tuaj yeem cuam tshuam lub emulsion lub zog ua ntej.
