When in film forming: the coating is poured into the raw material bottle, the raw material bottle is placed into the raw material bottle holder 13, one end of the feeding pipe 14 is placed into the raw material bottle, the transparent cover 29 is covered, and then the coating is started by pressing the film in the keyboard area 18 and the processing system is operated according to the preset program.
When the film forming program operates: the coating is heated to a set temperature by a heating device 22 in a raw material bottle, the mixture ratio of each coating is controlled by a feeding pipe 14 through a ratio control valve 24 after the coating is uniformly stirred by a magnetic stirring device 23, the coating flows into a waste material bottle through a discharging pipe 26 through a material conveying pump 25 after being uniformly mixed, and when the coating is coated, the coating flows into the waste material bottleAfter the materials meet the requirements, the rotating rod motor 28 drives the rotating rod 17, the nozzle 21 is rotated to the center of the film forming disc 20, the total amount of the inputted coating is controlled by controlling time and coating flow, the discharging pipe 26 is cut off by the discharging control valve 27 to output the coating, the material conveying pump 25 stops working, the rotating rod motor 28 drives the rotating rod 17, and the nozzle 21 is rotated to the center of the waste material bottle; at the same time, the rotating electric machine 31 is started and rotates at a speed omega according to the set requirement1After a certain time of rotation, at a rotation speed omega2And reversely rotating for a certain time, repeating the steps for a plurality of times, finally rotating for a period of time at the maximum rotating speed omega, and stopping after the film forming surface of the film forming disc 20 is flat.
As shown in fig. 7 and 8, the sectional coordinates of the particles on the film forming disk 20 are (r, z), the film forming disk 20 rotates at an angular velocity ω, the coating material to be examined is a newtonian fluid, and axial symmetry of the fluid flow on the film forming disk 20 is assumed; the influence of gravity on the fluid can be ignored, and the influence of evaporation on the thickness is not considered, and the balance between viscous force and centrifugal force on the fluid micro-cluster is as follows:
Figure BDA0003193511700000061
wherein upsilon isrFor the axial velocity of the micelles r, η is the viscosity of the liquid and ρ is the density of the liquid.
From the relationship of the boundary conditions, steady state conditions, fluid volume, thickness and membrane radius, the following can be calculated:
h=K(v/ω2R2)1/3
K=(81Q/16π)1/3
wherein h is the film forming thickness, R is the film forming radius, ω is the corresponding angular velocity, v is the kinematic viscosity of the fluid material, v ═ η/ρ, R is the radius of the film forming disc, and Q is the fluid material volume flow rate.
As can be seen from the formula, in the case where the radius, the volume flow rate, and the fluid viscosity of the film forming disk 20 are determined, the film forming thickness is dependent only on the rotation speed. Therefore, after the thickness is specified, the rotation speed satisfying the film formation requirement can be determined.
In particular, the method comprises the following steps of,taking polyurethane waterproof paint as an example: the radius of the film forming disc 20 is set as R, the film forming thickness required in the specification is 1.5mm +/-0.2 mm, the thickness is firstly set as h, and the total volume V of a sample for preparing the film of the polyurethane anti-coating paint is h pi R2The known section area of the discharge pipeline is pi r0 2The velocity of the liquid is v0Then the fluid flow Q ═ v0πr0 2Since V is Qt in the pipeline, t is V/(V)0πr0 2),v0Can be controlled by a pump, and can control the feeding amount by t, namely, the automatic film coating device controls the feeding volume by controlling the feeding time, thereby controlling the film coating thickness. The viscosity parameter of the polyurethane waterproof coating, the radius and the flow rate of the film forming disc 20 are input in the film forming program, and the corresponding rotating speed omega can be obtained by a calculation formula.
After the sample reaches the membrane disc 20, the program controls the membrane disc 20 to rotate, and the sample is subjected to the combined action of centrifugal force, friction force, viscous force and the like. Along with the rotation of the film forming disc 20, the sample diffuses outwards and continuously spreads over the film forming disc 20, the liquid rotates clockwise and anticlockwise for multiple times in the process, the liquid is agitated and collided, bubbles in the liquid are broken, the bubbles in the liquid can be basically eliminated, the film forming is more uniform until the rotating speed of the rotating disc reaches omega, at the moment, the sample rotates to be relatively static with the film forming disc 20 along with the film forming disc 20, and a uniform film meeting the thickness requirement appears on the film forming disc 20.
After the film forming surface of the film forming disc 20 is flat, the sound bell 32 makes a sound, the indicator lamp 19 is lighted, the film forming disc 20 is taken out, and a new film forming disc 20 is placed in. Three indicator lights 19 are provided, which respectively indicate the preparation of film formation, the instrument running and the instrument failure; when the instrument is in fault, the corresponding fault code is displayed on the control panel 10; when the indicator light 19 is not on, it indicates that the instrument is not powered or has failed.
During cleaning: the cleaning agent is poured into the cleaning bottle, the cleaning bottle is placed into the raw material bottle holder 13, one end of the feeding pipe 14 is placed into the cleaning bottle, the transparent cover 29 is covered, and then the cleaning is started in the keyboard area 18 and the processing system runs according to the preset program.
When the cleaning program runs: the heating device 22 heats the cleaning bottle to a set temperature, cleaning agent flows into the waste material bottle from the discharge pipe 26 through the feed pipe 14 and the delivery pump 25, and after the cleaning meets the requirement, the sound bell 32 makes a sound, the indicator lamp 19 is on, and the cleaning is finished.
During the test, the typical implementation test adopts a four-stage speed-increasing forward and reverse rotation mode, and the rotating speed of the film forming disc 20 is adjusted after the test is started as the following table 1:
TABLE 1 rotation parameter table of film forming disk in one film forming period
Numbering Rotational speed Forward rotation Time(s)
1 0.2ω Is just 30
2 0.2ω Inverse direction 30
3 0.5ω Is just 30
4 0.5ω Inverse direction 30
5 0.8ω Is just 30
6 0.8ω Inverse direction 30
