Research and Application of Electrostatic Powder Coating Model for Aluminum Profile
Aiming at the huge cost of labour and material resources for the uniform coating of aluminium profiles in practical pro-duction,a variable Gauss distribution model suitable for practical production is proposed.Through the analysis of the influencing factors of electrostatic powder coating on aluminium profiles,the control various method was used to carry out fixed position and continuous coating experiments,and the coating thickness experimental data were obtained.The fixed position experimental data were fitted based on Gaussian distribution.For the deviation problem of the sections far from the centre of the fitting model,the variable peak width method was used to optimize and modify the model,which further improved the fitting degree between model and experimental data.On this foundation,the influence of electrostatic voltage,powder flow rate and coating speed on the film thickness distribution was analysed through the experimental data,and the variable Gaussian distribution model of electrostatic powder coating under different parameters was established.Finally,coating experiment was carried out,and the film thickness distribution of aluminium profile product was in line with the results of model simulation and prediction,which shows that the model can accurately predict the distribution of film thickness under different parameters.In production practice,the application of the model can provide reliable simulation reference and production guidance for uniform coating,effectively reduce the times of adjusting parameters,and improve the production efficiency of enterprises.
