Manufacturer is made to be used.However, how Rational choice electrophoretic coating, white body sheet material and its pre-treating technology, come obtain preferably
Film effect on electrophoresis, turn into the key issue of current car paint industry.
Electrophoretic coating new at present is all water paint, according to electrophoresis, principles of electro-deposition in electrochemistry in metal（It is cloudy
Pole）Surface deposits film forming.But due to the mass discrepancy of sheet material, pretreatment mode, electrophoretic coating or each batch sheet material, cause electricity
Swim effect it is unstable, under the conditions of same construction technology, on electrophoresis film effect also can difference it is very big, it is therefore desirable to Yi Zhongke
The method that good directive function is played with the selection to sheet material and electrophoretic coating.
The content of the invention
The technical problems to be solved by the invention are to provide film method on a kind of electrophoretic coating of automobile board, and this method will
After sheet material classification, the upper film effect that conventional coating corresponds to sheet material is obtained by orthogonal test, then can be according to actual production need
Ask, targetedly choose most suitable coating and sheet material is processed, the selection to sheet material and electrophoretic coating is played well
Directive function, be particularly suitable for the demand of personalized definite value vehicle.
What the present invention was realized in：Film method on a kind of electrophoretic coating of automobile board, comprises the following steps：
S1. coating model data storehouse is established, several electrophoretic coating will be chosen and be filled into coating model data storehouse；
S2. according to sheet material type, if sheet material is divided into Ganlei；
S3. an electrophoresis time and several electrophoretic voltages are set, all kinds of sheet materials are obtained in a series of electrophoresis electricity by orthogonal test
Film test on the electrophoretic coating of the corresponding different coating of pressure；
S4. after the sheet material drying after upper film, it is input to using the electrophoretic coating thickness of film thickness gauge sheet material measurement, and by all parameters
In coating model data storehouse, now coating model data storehouse includes one-to-one coating model, sheet material type, electrophoretic voltage
With electrophoretic coating thickness data group；
S5. electrophoretic coating is selected according to the sheet material type and production requirement of supplied materials to be processed the sheet material.
In the step S2, the sheet material is divided into four classes, respectively cold-reduced sheet, galvanized sheet, high-strength plate and thermoforming plate.
In the step S3, the electrophoretic voltage sets high, medium and low third gear, respectively 90V, 120V, 150V.
In the step S3, in film test on carrying out electrophoretic coating, voltage speedup is set as 2V/s or 3V/s.
In the step S5, electrophoretic coating thickness is relatively low when being chosen at low-grade voltage, and the electrophoretic coating in high-grade voltage
The higher coating of thickness is processed to sheet material.
After film method classifies sheet material on the electrophoretic coating of automobile board of the present invention, conventional coating is obtained by orthogonal test
The upper film effect of corresponding sheet material, then can targetedly choose most suitable coating to plate according to actual production demand
Material is processed, and it is relatively low and electric in high-grade voltage to choose electrophoretic coating thickness when mode is low-grade voltage in most cases
The higher coating of swimming coating thickness；But for required precision is especially high or production efficiency requires extra high sheet material, can also
Electrophoretic coating thickness is minimum when directly choosing low-grade voltage or electrophoretic coating thickness highest coating during high-grade voltage, to sheet material and
Good directive function is played in the selection of electrophoretic coating, is particularly suitable for the demand of personalized definite value vehicle.
