Embodiment 1

[0037] Artificial stone color difference control methods mainly include color quality control of raw materials and pigments, pigment dyeing performance research, and product color formula simulation.

[0038] The main instrument of this method is 3nh spectrophotometer YS3020, supporting color quality management software and color matching software.

[0039] The method for controlling the chromatic aberration of artificial stone comprises the following steps:

[0040] S1. Color quality control of raw materials and pigments

[0041] Use the color difference meter to call out the L*a*b* chromaticity value of the carbon black sample, and measure the color difference of the new carbon black sample. The test conditions are: D65 light source 8° observation, the test index is the color difference ΔE, and the raw material with the color difference ΔE less than 0.5 is judged as qualified;

Abstract

The invention discloses an artificial stone color difference control method, which belongs to the technical field of color difference control. The method comprises the following steps: S1, controllingcolor quality of raw materials and pigments; S2, testing dyeing performance of the pigments; and S3, simulating a product color formula. According to the artificial stone color difference control method of the invention, the color quality condition begins to be controlled from the source of the raw materials and pigments, the product production formula is adjusted by adopting a great amount of pigment data and computer color matching simulation to assist the technicians, so that the color difference of products of different batches can be reduced, thereby improving the product development efficiency, shortening the research and development production period, reducing the corporate production cost, improving the product quality, and bringing about greater benefit to the artificial stone production enterprise.

Description

technical field [0001] The invention belongs to the technical field of color difference control, and in particular relates to a method for controlling color difference of artificial stone. Background technique [0002] At this stage, when the color difference of artificial stone fluctuates between different batches of raw materials and pigments, under normal circumstances, technicians often fine-tune the formula based on past experience, but the produced artificial stone and the sample still have obvious color difference. [0003] In addition, introducing the color difference meter into the sample production, and testing the color difference and phase deviation provided by the color difference meter, although the speed of sample coloring can be improved, it does not solve the problem of large color difference between batches at all. Contents of the invention [0004] The object of the present invention is to provide a method for controlling the color difference of artifici...
