Evaporation coating equipment and technology Vacuum evaporation coating equipment is mainly used for vapor deposition of metal film (aluminum, chrome, tin, stainless steel, etc.), colorful film imitation gold film, etc. on the surface of pretreated plastics, ceramics, etc. Beautiful, inexpensive plastic, ceramic surface metallized products. Widely used in arts and crafts, decoration, lamps, furniture, toys, wine bottle caps, women's shoes heels and other fields. Such as multi-functional coating technology and equipment (evaporation coating machine with RF plasma polymerization), designed for automotive and motorcycle lamps, complete in a vacuum chamber with evaporative aluminizing and RF plasma plating protective film, after this coating The luminaire has a "three-proof" function.
Naoh (sodium hydroxide, commonly known as caustic soda, caustic soda), as a common chemical solution in this process, mainly serves the following two purposes:
1 Check whether the evaporation coating has deplating: the specific method: configure 1% NaOH solution, drip on the surface of the product within 10 minutes, there is no obvious deplating on the surface of the product, such as car lamp accessories
2 Electroplating parts rinsing: non-beer parts themselves, but due to oiling, evaporation, dyeing process problems caused by defective products such as dirty tanks, scratches, color deviations, etc., can be washed with a hot caustic soda aqueous solution . crafting process:
a). Add caustic soda (NaOH) to water, the ratio is about 1:20) to make a supersaturated solution, electric boiling
b). Place the rinsing member in it for about 30 minutes to remove the plating oil layer by itself.
c). After taking out, washing with water and then performing a series of processes after degreasing
The scope of evaporation:
1. Construction hardware: bathroom hardware (such as faucet). Door lock. Door Handle. Bathroom, door lock, hardware hinge, furniture, etc.
2. Watchmaking industry: can be used for the watch case. Strap coating, crystal products
3. Other hardware: leather hardware. Stainless steel cutlery. Eyeglass frames, knives, molds, etc.
4. Large workpiece: car wheel, stainless steel plate. sign. Sculpture, auto parts such as lights, etc.
5, stainless steel tubes and plates (various types of surface)
6, furniture, lamps, hotel appliances
7, locks, handles, bathroom hardware, golf heads, stainless steel cutlery, blood and other hardware products plated super hard decorative film.
8, watches, straps, glasses, jewelry and other decorations plated super wear-resistant decorative (gold and silver) nano-film and nano-film and nano-layered film.
The NaoH (sodium hydroxide) concentration meter produced by ATAGO, caustic soda concentration meter and caustic soda concentration meter can conveniently control the concentration of the solution to ensure the high quality of the production process.
