JPS57162663A - Device for painting of two-pack type coating material - Google Patents

Abstract

PURPOSE: To coat paint satisfactorily by connecting a body provided with a base material tank and a sub-material tank for painting and a high pressure air supplying means to a painter thereby flowing out the base material and the sub-material with the high pressure air and spraying these under mixing.

CONSTITUTION: While electric heaters 5, 5 are kept at prescribed temp., stop valves 25B, 35A, and 26B, 36A as well as 39B, 41B are opened. Next, a high pressure air supplying means K is operated to introduce a base material S through a discharge pipe 25, a connecting pipe 48 and a conduit 35 into the 1st mixing chamber 33 of a painter 30. On the other hand, a sub-material F is introduced through a discharge pipe 26, a connecting pipe 49 and a conduit 36 into the 1st mixing chamber 33. Thereby, the base material S and the sub-material F are mixed, and the mixture is introduced into the 2nd mixing chamber. The mixture is again mixed by the high pressure air fed through a connecting conduit 51 and a conduit 39, and is fed through a discharge port into the liquid feed pipe 46 of a nozzle part 44. Since the high pressure air is fed into a conduit 41 by this, the air is mixed with the liquid mixture, which is forced toward the ejection port 45A of the part 44. The high pressure air is introduced through a conduit 51 and a feed pipe 47, and the liquid mixture is sprayed by the high pressure air out through the outside pipe 45 of the part 44.
