Common knowledge of coating: the main factors to be paid attention to in the selection of pigments for coil coating

Core tip: China new coating news: coil coating is a special coating suitable for metal coil coating process, the coating process is to use roller coating machine for continuous coating of strip This puts forward the requirement of rapid drying of coil coating at high temperature At the same time, the temperature of steel plate is as high as 220 ~ 260 ℃ When passing through the oven, the ambient temperature is as high as 400 ℃ Therefore, the heat resistance of coil coating becomes extremely important As the coil coating is mainly used outdoors, it is required to have excellent weather resistance The coil coating must pass at least 5 years of Florida exposure test To the room Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: China new coating news: coil coating is a kind of special coating suitable for metal coil coating process, the coating process is to use roller coating machine for continuous coating of strip This puts forward the requirement of rapid drying of coil coating at high temperature At the same time, the temperature of steel plate is as high as 220 ~ 260 ℃ When passing through the oven, the ambient temperature is as high as 400 ℃ Therefore, the heat resistance of coil coating becomes extremely important As the coil coating is mainly used outdoors, it is required to have excellent weather resistance The coil coating must pass at least 5 years of Florida exposure test For indoor steel household utensils and electrical appliances with precoated coil coating, the requirements for light resistance are very high When exposed to the sun under the xenon lamp, the light resistance must be above grade 7 as measured by the blue wool ruler Coil coating is widely used in building steel plate cladding, which can effectively resist the erosion of various industrial pollutants In addition, when coil coating is used on the surface of household appliances Due to frequent contact with household chemicals or detergents, chemical resistance must also be considered Generally, the film thickness of coil coating is between 20-35 μ M The pigment used must give enough covering power to the coil coating within the film thickness range, otherwise, the slight thickness change of the film will lead to the appearance of color difference The coil coating mainly uses metal oxide warm phase pigments (inorganic composite coloring pigments) with excellent covering power, such as pigment yellow 53, pigment Brown 24, blue 28, blue 36, green 26 and green 50 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,
