The lamp protective film equipment developed by ZHENHUA solves the long-standing problem that PC / ABS lamps need to be sprayed with paint. It allows the injection molded parts of the lamps to directly enter the vacuum chamber to complete the evaporation and protective film coating process at one time, so as to prevent secondary pollution without bottom spraying or surface spraying.
The film coated by the equipment has good uniformity, and its acid resistance, alkali resistance, salt fog resistance, water resistance and other indicators meet international standards. This equipment has been widely used in the market by many domestic and foreign brand lamp manufacturers to produce many brand lamps.
1. Adhesion: no falling off after 3M adhesive tape is directly pasted; The shedding area after cross cutting is less than 5%.
2 Silicone oil performance: the line thickness of the water-based marking pen changes.
3. Corrosion resistance: after titration with 1% NaOH for 10min, the coating has no corrosion.
4. Immersion test: After soaking in 50 ℃ warm water for 24 hours, the coating does not fall off.
The equipment is a vertical double door structure. It is a composite equipment integrating DC magnetron sputtering coating technology, resistance evaporation coating technology, CVD coating technol...
In the vacuum chamber, the coating material is vaporized and deposited on the substrate by using the resistance heating method, so that the surface of the substrate can obtain metal texture and ach...
