A method and device for testing the properties of modified raw lacquer pigments

Abstract

The invention discloses a method and a device for testing the performance of modified raw lacquer paint. The device is structurally characterized in that a primary ink box is connected with a secondary ink box by virtue of a liquid pump, the secondary ink box is connected with a nozzle to supply ink, the signal output end of the sensor is connected with the signal input end of a liquid level control plate, the signal output end of the liquid level control plate is connected with the signal input end of a liquid pump, the power supply input end of the liquid level control plate is connected with the power supply output end of a power supply plate A, and the secondary ink box supplies ink to the nozzle; the signal input end of the nozzle is connected with the signal output end of a nozzle signal plate, the signal input end of the nozzle signal plate is connected with the signal output end of a control button plate, and the power supply input end of the nozzle signal plate is connected with the power supply output end of a power supply plate B. The method and device disclosed by the invention have the advantages that (1) the linear state and the film forming condition of the raw lacquer paint are directly and quickly detected and the spraying performance of the modified raw lacquer is tested; and (2) the spraying performance corresponding to the modified raw lacquer can be detected by virtue of replacing the nozzle, so that the method and device have great application significance in industrial spraying of the modified raw lacquer.

Description

technical field [0001] The invention relates to a method and device for testing the properties of modified lacquer pigments, belonging to the technical field of lacquer pigment testing. Background technique [0002] Traditional raw lacquer has deep color and high viscosity. In the process of lacquerware production and use, due to the restriction of natural factors, the drying conditions are harsh, and certain temperature and humidity conditions need to be controlled. The production cycle is long and the labor productivity is very low. It is difficult to mass-produce large-scale industries. spraying. At present, the research on modified raw lacquer uses natural raw lacquer as raw material, adopts biorefining and micro-dispersion devices, and uses nanotechnology and the introduction of modifiers, catalysts, solvents, natural environmental protection additives and other methods to change the fine particles, Viscosity, dry film forming time, film brightness, film color, film gl...
