The specific embodiment
Below the present invention will be further described in detail.
As shown in Figure 1, a kind of white device of coating generation mist that prevents, comprise that one is provided with the casing 20 of opening, described casing 20 is connected with vavuum pump 100 through an exhaust tube 110, in described casing 20, be also provided with air bleeding valve, described casing 20 openings are provided with for opening and closing the chamber door 50 of casing, casing 20 edge of opening places are provided with sealing ring 40, the sealing of casing 20 during with raising chamber door 50 tube wall, in casing 20, be provided with vacuum material chamber 10,10 tops, vacuum material chamber are also provided with peg 30 that can hanging articles.
Described casing 20 belows are provided with control cabinet, are provided with control circuit chip in described control room, described control circuit be connected with vavuum pump 100.Control cabinet outside is provided with control panel, control panel is provided with power switch and vacuum pump switch 60, time control table 70, pressure vacuum gauge 80, air escape cock 90, and described power switch is connected with control circuit with vacuum pump switch 60, time control table 70, pressure vacuum gauge 80, air escape cock 90, air bleeding valve.
This device is used step:
(1) adopt existing brushing, spraying or impregnating method to carry out application to object;
(2) object painting being installed is put into vacuum chamber fast, starts vacuum extractor casing is vacuumized;
(3) after application of vacuum a period of time, open vent valve, take out object and carry out dry solidification.
Vacuum processing time can be according to factors such as the humidity of the power of the type of the size of processed object and vacuum chamber, coating type, selected solvent, vavuum pump and environment and temperature, and the time is at least greater than 3S.The method has been introduced fast vacuum processing in coating application process, when accelerating the little molecule organic solvent volatilization of low boiling, reduced the coating that causes due to factors such as construction environment humidity height particularly transparent paint film there is blushing.
