Coating technology: a comprehensive analysis of the coating color matching process in small and medium-sized coating enterprises

Core tip: for small and medium-sized coating enterprises, it is impossible to use a computer color matching system that can easily reach hundreds of thousands, and there are also great difficulties in human resource allocation At present, most small and medium-sized coating enterprises still use manual color matching In the process of color matching, some colors provided by customers can be directly matched by color cards, However, some colors that are not in the color card can only be matched by the experience of technicians The following describes the matching process of waterborne coatings of Longfeng Chemical Coatings Co., Ltd., a new type of coating net entity: 1 Prepare 10kg or appropriate base coating, pay attention to the base coating Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: for small and medium-sized paint enterprises, it is impossible to use a computer color matching system that is often hundreds of thousands of colors, and there are great difficulties in human resource allocation At present, most small and medium-sized paint enterprises still use manual color matching In the process of color matching, some colors provided by customers can be directly matched by color cards, However, some colors that are not in the color card can only be matched by the experience of technicians The following describes the matching process of waterborne coatings of Longfeng Chemical Coatings Co., Ltd., a new type of paint net entity: 1 Prepare 10kg or appropriate amount of basic coatings, pay attention to three types of basic coatings: light, medium and dark, and select the basic coatings according to the depth of the sample color 2 Prepare the color paste, analyze which color paste is needed according to the experience of color matching, and calculate the appropriate addition amount In the process of choosing color paste, we should also pay attention to the difference between organic pigment and inorganic pigment, which color paste is suitable for dispersant, wetting agent, defoamer and so on in the basic paint, so as to achieve the best effect of color matching 3 In the process of adding the color paste, it is necessary to add the basic coating slowly and evenly and stir the base coating at the same time After adding one color paste, it is necessary to mix it well to avoid local color difference Then add the second color paste, and sample and compare with the sample plate at any time In the process of comparison with the sample plate, it is necessary to wait for the film to dry before comparison, and it should be carried out in an environment with sufficient light, so as to ensure that the test is consistent with the color of the sample plate Precautions: 1 During the mixing process of adding color paste, control the speed of the mixer to prevent the overflow of the base coating, resulting in errors 2 After the completion of color matching, the amount and order of color paste added in the process of color matching shall be archived in detail for future use 3 Before adding the color paste, you must shake the color paste evenly, and then absorb it Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
