Njira yoyika nthunzi ya vacuum nthawi zambiri imaphatikizapo masitepe monga kuyeretsa pansi, kukonzekera musanakutire, kuthira nthunzi, kutola zidutswa, chithandizo cham'mbuyo, kuyesa, ndi zinthu zomalizidwa.
(1) Kuyeretsa pamwamba pa gawo lapansi. Vacuum chipinda makoma, gawo lapansi chimango ndi zina padziko mafuta, dzimbiri, zotsalira plating zakuthupi n'zosavuta asamasanduke nthunzi mu vakuyumu, mwachindunji zimakhudza chiyero cha filimu wosanjikiza ndi mphamvu yomangira, ayenera kutsukidwa pamaso plating.
(2) Kukonzekera musanavale. Kupaka vacuum yopanda kanthu pamlingo woyenera wa vacuum, gawo lapansi ndi zida zokutira zopangira pretreatment. Kutenthetsa gawo lapansi, cholinga chake ndikuchotsa chinyezi ndikuwonjezera mphamvu yolumikizira nembanemba. Kutenthetsa gawo lapansi pansi pa vacuum yapamwamba kungathe kuwononga mpweya wa adsorbed pamwamba pa gawo lapansi, ndiyeno kutulutsa mpweya kuchokera m'chipinda chosungiramo mpweya pogwiritsa ntchito mpope wa vacuum, zomwe zimathandiza kupititsa patsogolo kutentha kwa chipinda chophimba, chiyero cha filimu yosanjikiza ndi mphamvu yogwirizanitsa ya filimuyo. Ndikafika digirii zingalowe, woyamba evaporation gwero ndi m'munsi mphamvu ya magetsi, filimu preheating kapena chisanadze kusungunuka. Pofuna kupewa evaporation kwa gawo lapansi, kuphimba evaporation gwero ndi gwero zakuthupi ndi baffle, ndiyeno kulowa apamwamba mphamvu ya magetsi, ndi ❖ kuyanika zakuthupi mofulumira usavutike mtima kwa evaporation kutentha, evaporation ndiyeno kuchotsa baffle.
(3) Kusanduka nthunzi. Kuphatikiza pa evaporation siteji kusankha yoyenera gawo lapansi kutentha, plating zakuthupi evaporation kutentha kunja mafunsidwe mpweya kuthamanga ndi yofunika kwambiri chizindikiro. Mafunsidwe a mpweya kuthamanga ndi ❖ kuyanika chipinda vacuum, amaona pafupifupi ufulu osiyanasiyana mamolekyulu mpweya kusuntha mu evaporation danga ndi ena evaporation mtunda pansi nthunzi ndi otsalira maatomu mpweya ndi chiwerengero cha kugunda pakati pa nthunzi maatomu.
(4) Kutsitsa. Pambuyo makulidwe a filimu wosanjikiza kukwaniritsa zofunika, kuphimba evaporation gwero ndi baffle ndi kusiya Kutentha, koma nthawi yomweyo kutsogolera mpweya, kufunika kupitiriza kuziziritsa pansi zingalowe zikhalidwe kwa nthawi kuziziritsa, kupewa plating, zotsalira plating zakuthupi ndi kukana, evaporation gwero ndi zina oxidized, ndiyeno kusiya kupopera, ndiyeno inflate the substrate kutsegula substrate.
