Automatic paint mixing method and system for coating aluminum profile with fluorocarbon

Abstract

The invention discloses an automatic paint mixing method for coating an aluminum profile with fluorocarbon. The method comprises the following steps: a first solvent for a to-be-sprayed paint is diluted to optimum viscosity so as to form a first diluted paint; a second solvent for the to-be-sprayed paint is diluted to optimum viscosity so as to form a second diluted paint; the using amount of the paint required by an object to be coated is set; the air temperature in a spraying room is measured in real time; according to the air temperature, the mixing ratio of the first diluted paint and the second diluted paint is calculated; according to the using amount of the paint and the mixing ratio, the first diluted paint and the second diluted paint are extracted respectively; mixing treatment is performed on the extracted first diluted paint and second diluted paint; after the extracted first diluted paint and the extracted second diluted paint are mixed uniformly, the object to be coated is coated with the mixture. The invention further discloses an automatic paint mixing system for coating the aluminum profile with the fluorocarbon. Through the adoption of the method and system, the air temperature and humidity in the spraying room are measured in real time, so that the regulation of the ratio of the diluted paints is achieved, the integration of paint mixing and spraying is achieved, the matching ratio of solvents is accurate, and the using amount of the diluted paints is accurate.

Description

technical field [0001] The invention relates to the technical field of fluorocarbon spraying, in particular to an automatic paint adjustment method and system for fluorocarbon spraying of aluminum profiles. Background technique [0002] Before spraying fluorocarbon coatings, appropriate organic solvents must be added to the coatings for dilution to ensure that the viscosity of the diluted coatings, the volatility of the solvents contained, and the solid content are in line with the working environment, that is, reduce the viscosity to ensure the fluidity of the coatings. Good performance, the use of an appropriate solvent is for the coating film after spraying to be in the best leveling state when the solvent in it evaporates. Different types of solvents have different dilution capabilities and volatilization speeds, and in different working environments, the volatilization capabilities of solvents are also different. If the volatilization rate of the solvent in the coating...

AI Technical Summary

Problems solved by technology

The whole process is manually operated, and the operator mixes different solvent ratios based on experience, so that the selection of solvent ratio and the amount of use cannot be accurately controlled

At the same time, since the volatility of each solvent will change with temperature, the operator cannot accurately grasp the solvent volatility value, and the solvent mixing ratio will be inaccurate

In addition, because the paint is prepared in advance and then sprayed, if the temperature and humidity changes during the spraying process, the diluted paint will not be conducive to the spraying operation, affect the product quality, and need to be re-deployed.

[0004] Therefore, in view of the problems of inaccurate solvent ratio and slow response to temperature and humidity changes in the current industry spraying operation, it has become an urgent problem to develop an automatic paint mixing method and system for fluorocarbon spraying of aluminum profiles.
