The 3rd step: the small size plate sample workpiece of carrying out the front cleaning of paint is put into and is got rid of in film machine, coating is put in to small size flat boardThe center of exemplar makes it to carry out centrifugal finishing, and coating is got rid of to whole surface; Produce the film machine that gets rid of of centrifugal force, its rotating speedDivide three sections of controls with the time, 800 revs/min of first paragraph rotating speeds, the time is 5 seconds; 1000 revs/min of second segment rotating speeds, the time is 10 seconds;2000 revs/min of the 3rd section of rotating speeds, the time is 10 seconds.
The 4th step: after application completes, take out exemplar and dodge dry 3-5 minute, dry by coating specification in baking oven.
The 5th step: carry out thickness detection, precision can reach 0.1 μ m, and the coating uniformity is high.
The 6th step: if need application again, dodge after dry 5 minutes in coating, repeat to implement from the 3rd step.
Good effect of the present invention is that the preparation process of coating is easy, and the artificial and spraying can avoid applying coating time is establishedStandby error, enforcement of the present invention saves time, laborsaving, province's coating, and the accuracy of prepared coating film thickness is very high, can reach 0.1 μ m.
The principle of invention is: under the effect of centrifugal force, coating gets rid of to whole surface from center, unnecessary coatingGet rid of to edge. Produce rotating speed and the time of centrifugal force by control, thereby obtain very even below 20 μ m of coating thickness(coating thickness precision can reach m) paint film of 0.1 μ.
Testing equipment adopts the commercially available general film machine that gets rid of, and the key technical indexes sees the following form.
Brief description of the drawings
Fig. 1 is process principle figure of the present invention.
Detailed description of the invention
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with specific embodiment partyThe present invention is described in further detail for formula.
The film uniform coating preparation of embodiment 1 individual layer finish paint
The working viscosity of finish paint is 20 seconds-30 seconds (being coated with-4 flow cups detects). If former paint viscosity is excessive, can suitably addEntering finish paint paint special diluting agent dilutes. Be put into by carrying out the 2cm × 2cm small size plate sample workpiece cleaning before paint the film machine that gets rid ofIn, the center that the coating of working viscosity is put in to small size plate sample workpiece makes it to carry out centrifugal finishing, and coating is got rid of to wholeOn individual surface; The film machine that gets rid of that produces centrifugal force, its rotating speed and time are divided three sections of controls, 800 revs/min of first paragraph rotating speeds, the time is 5Second; 1000 revs/min of second segment rotating speeds, the time is 10 seconds; 2000 revs/min of the 3rd section of rotating speeds, the time is 10 seconds. Such parameter is establishedPut, uniform film thickness degree is relatively good. If the error departing from is excessive, effect is just different.
After application completes, take out exemplar and dodge dry 3-5 minute, in baking oven, dry by coating specification.
Carry out thickness detection, according to coating solid part difference, the coating layer thickness obtaining is conventionally between 25 μ m-35 μ m, oftenThe coating layer thickness precision of sheet can reach 0.1 μ m, and the coating uniformity is high.
The film uniform coating preparation of embodiment 2 single-layer metal primary colours paints
The working viscosity 10 seconds-20 seconds (being coated with-4 flow cups detects) of Metal Substrate colored paint, if former paint viscosity is excessive, can be suitableAdd Metal Substrate colored paint paint special diluting agent to dilute. Be put into carrying out the 2cm × 2cm small size plate sample workpiece cleaning before paintGet rid of in film machine, the center that the coating of working viscosity is put in to small size plate sample workpiece makes it to carry out centrifugal finishing, makes coatingGet rid of to whole surface. It is characterized in that: produce the film machine that gets rid of of centrifugal force, its rotating speed and time are divided three sections of controls, and first paragraph turns800 revs/min of speed, the time is 5 seconds; 1000 revs/min of second segment rotating speeds, the time is 10 seconds; 2000 revs/min of the 3rd section of rotating speeds, the timeIt is 10 seconds.
