What are the process of automatic screen printing machine Silk screen print emulsion and coating solution (ammonium dichromate solution). Fully automatic screen printing mechanism version of emulsion and coating solution when 10:1 and the weight of the qom slurry went down. Slowly the worry, to second liquid, mix. The following should be paid attention to at the same time, light, or failure of the utility. Emulsion after set, slightly tilted emulsion flow network input power, scraping, swept the top of the mesh. Then, evenly daub mesh cloth. Again with the same method of photographic emulsions forward two sides all the time, and then use hair dryer dry-hot wind. Screen immediately after dry photosensitive plate burning, lest all light, indoor lighting lighting use 200 w cannons, two flat screen or 20 w fluorescent lamp is lighting, but also film coating Yang on the table, and then cover glass of the mask and two iron sandwiched between left and right sides, lighting the card from the screen is the appropriate distance between 20 to 30 cm. Sensitive time about 8 to 10 minutes. Photosensitive screen, after washing, light sponge brush washing water is just right, not too strong, mesh. YuanYang plate, should be paid attention to when the screen piece of black part to flow, the white part is transparent form hard film net cloth prison clearly stop mode. Water rushed out of the screen design, then dry cloth cover screen on both sides of the water. Natural drying screen and blow dry. This version of the complete process fully automatic screen printing machine manufacturing. |
