Description of drawings
Fig. 1 is the schematic flow sheet that vacuum plating unit of the present invention is made plated film ambetti mirror.
Embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment
As shown in Figure 1, a kind of preparation method who makes plated film ambetti mirror with vacuum plating unit may further comprise the steps:
1, to workpiece such as glass clean, drying, be contained on the work rest then, because metallic membrane and glass surface are in conjunction with the main London force that relies on, therefore, the cleanliness factor of glass surface directly influences the sticking power of metallic membrane, can clean with tap water and nylon brush as new glass, and then clean with tap water and pure water respectively, use cold wind and hot blast drying then successively.Above matting can be with special cleaning machine clean.The length of metal has very big influence to the thickness of metallic diaphragm, therefore the titanium silk is cut into first group of tungsten evaporator group (battle array source) that certain-length is packed into and is arranged in vacuum chamber, is cut into certain-length after again copper wire and titanium skein silk being closed and packs into and be arranged in second group of tungsten evaporator group of vacuum chamber; After treating that wire installs, the workpiece such as glass of cleaning-drying are contained on the work rest, the distance of general glass pieces surface lies tungsten evaporator group is 20 to 50 centimetres and is advisable again.
2, begin to vacuumize after work rest being sent into vacuum chamber, open sliding vane rotary pump or slide valve pump successively, lobe pump reaches≤10Pa to vacuum tightness.
3, make vacuum tightness drop to 20～40pa to the vacuum chamber applying argon gas, regulate bombarding current to 0.1～1A, workpiece was carried out ion bombardment after 4～6 minutes, be evacuated down to less than 6X10 then
-2Pa; After charging into argon gas, regulate bombarding current, as preferred current setting is 0.3 to 0.8A, workpiece surface such as glass were carried out ion bombardment 4～6 minutes, can remove the spots such as dust of workpiece surface like this,, can smash into small molecules to the organic long-chain molecule of workpiece surface such as glass such as oil molecule and come off because argon ion kinetic energy is big, make workpiece such as glass reach high cleanliness factor, the condition that provides for following metal-coated membrane.
4, open the power supply of first group of tungsten filament vaporizer, regulate evaporation current 1000 to 1200A, the speed of metal film deposition is 5～15nm/min, according to the different metal film thickness that will obtain, the general evaporation titanium silk time was 15～30 minutes, as preferred evaporation titanium silk 20 minutes; Examine the counting of vacuumometer this moment, at any time regulate evaporation current, the titanium silk is evenly evaporated, evenly be attached to the glass pieces surface then, form the peptide metal tunic of the first layer densification, open the power supply of second group of tungsten filament vaporizer then, regulate electric current 1000 to 1200A, the speed of metal film deposition is 5～15nm/min, according to the different metal film thickness that will obtain, evaporated stranded copper wire and titanium silk 15～30 minutes, as the stranded copper wire of preferred evaporation and titanium silk 20 minutes, can be on the first layer peptide metallic diaphragm plated with copper metallic diaphragm and titanium metal rete successively again, shutdown then, take out glass, japanning in case of necessity, thus obtain from shallow dark brown a series of look mirror glass products to dark brown.
The preparation method who makes plated film ambetti mirror of vacuum plating unit provided by the invention, can conveniently control evaporation of metals speed and evaporation time, and can be according to actual needs, adjust the thickness of the first layer titanium metal film, and then plated with copper metallic diaphragm and titanium metal rete, thereby finally obtain the glassy product of shallow dark brown a series of different colours to dark brown.
