Abstract

A continuous painting method on one side of a moving substrate (1) using a heat-resistant polymer base compound. Consisting of The bar is pre-heated in a preheated kiln (2) at a temperature above the glass transition temperature. Of the paint ingredients Driving hard lumps (8) of the paint mixture Hit the bar That at a predetermined speed To cause the liquid paint to melt from the cubes and stick to the bar At a clearly controlled binding rate, the binder, which for thin paint coatings, is intermittent. It is spread over the surface of the strip by means of compression rolls (14) and that emerges then forms a layered coating of wet paint. A line of liquid paint (17) will form on the band on the top of the current above the compression roll. The cube speed may be adjusted to respond to the size of the strip that emerges, then travels through a gray curing oven (5) and sink (6) to complete the process.

Claims (3)

1. Method of continuous painting At least part of at least one side. Of the moving substrate, a heat-resistant (thermosetting) polymer-based paint mixture with a glass transition temperature consisting of a To heat the bar Before the preheating temperature above the glass transition temperature Pre-heated bar movement And then at the bar speed that has been set before Driving the solid blocks of the paint mixture along The axis of the cube hits that side of the moving band at a predetermined lump speed to make the liquid binder of the paint mixture. Melted from it and carried Away from the cube onto one side of the bar And later heating the island In order to obtain the heat-resistant coating of the paint, at least part of the said side of the strip. 2. Method according to claim 1 that includes the next steps in the binder. 3. Method according to claim 2, where the binder does not continue without The barrier from edge to edge of the said bar And consists of the next step in the spread The island binder So that it can go further Without obstructing from the edge to The edge of the said bar Before making it smooth 4. Method for claim 3 where the loaf is narrower than the band 5. Method for claim 3 where the loaf is the same width But the binder is not continuous. 6. Method of claim 3 where such expansion It is the result of a flattening device that produces a plenum. Of the liquid paint mixture extends from edge to edge. Of the bar And at semi-speed, the cubes are controlled as needed to maintain The least part of the plenum at most constant magnitude 7. Clause 6, where such part of the Plenum. It consists of two ends of it, each adjacent to the edge of the band. 8. The instrument produces the effect of the method of claim 1 consisting of A machine that makes the bar move at a predetermined band speed and then follows the Predetermined And the tool can also be executed on the tab As it moves along Way through that Such tools include The machine heats the bar before Preheating temperature Melt-off island catcher That are used to capture the cubes and Drive the cubes along the axis of the cube at the specified speed to hit the hot side of the strip. Where the binder Was applied to Side of the bar And a curing machine where the binder is further heated at the incubation temperature. To produce a heat-resistant coating layer of the paint on the bar 9. The tool according to claim 8 also includes an expander to spread the layer. Hold the adhesion across the bar from its edge to its edge 1 0. The tool according to claim 8 that also includes a smoothing machine. To smooth the grasp of the island 1 1. Apparatus according to claim 9, where such an expander produces a smooth line of liquid paint that extends from the edge to the edge of the strip. And also contains Feed speed detector And controls that respond to the size of at least The most part of the genre To calculate the velocity of the cube 1 2. Tools according to claim 8 that also include Dual-action expander and smoothing / smoothing tool consisting of driven compression rolls. The power to go out Diagonal type of the said bar And has been adjusted to compress onto the island layer And bolster Which enhances the bar against the pressure of the compression roll 1 3. Tools according to claim 12, where such part of the extrusion surface of the compression roll Such substances have been exposed to the binder. Move in the same direction as that bar at a speed from 1 to 20% of that bar's speed.
