Coating knowledge: summary of characteristics of Xinying coating series testing equipment

Core tip: Xinying testing instrument has developed a series of equipment in coating testing, which can test various properties of coating, including coating covering power, drying time, wear resistance, etc The covering power can cover the minimum amount of paint required for the base color no longer to appear It is expressed in (g / m2), and the common method is grid method Use a 100 × 200 mm black-and-white grid plate as the base plate, spray or brush the paint film until it is completely covered; or cover it on the black-and-white grid plate after painting with glass plate, and measure the consumption by weighing Usage or covering area, reflecting the area that can be covered by a certain amount of paint, 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 Home of coatings: Xinying testing instrument has developed a series of equipment in coating testing, which can test various properties of coating, including coating covering power, drying time, wear resistance, etc The covering power can cover the minimum amount of paint required for the base color no longer to appear It is expressed in (g / m2), and the common method is grid method Use a 100 × 200 mm black-and-white grid plate as the base plate, spray or brush the paint film until it is completely covered; or cover it on the black-and-white grid plate after painting with glass plate, and measure the consumption by weighing The amount of paint used, or covering area, reflects the area that can be covered by a certain amount of paint, expressed by the amount of paint required per square meter Through the test of black and white covering power tester, the dispersion and covering degree of powder can be measured by simple and fast method, which is better than the reflection value measurement method It is suitable for the production and quality control of flow characteristics to determine the flow performance of paint, so as to ensure the elimination of brush marks after coating, the leveling performance after spraying, and the non flowing characteristics Determination of burnability of paint film after drying the paint film shall be sanded to a smooth and matte degree of difficulty During grinding, the paint film shall not be damaged locally, and the drying time is the main index of the paint Generally, it is divided into: surface drying is referred to as surface drying or touch finger drying, which means that there is a very thin film on the surface after the paint film is applied, and the paint film does not stick to hands Put the degreased cotton ball on the surface of the paint film If it can be blown away without cotton adhesion on the surface, it is surface drying Surface drying time is also important for soil application The actual drying is short for the actual drying Can use cotton ball, filter paper, plus a tester to give a certain pressure, determine the non stick time It is also a measurement method to use the blade to scrape and check When the paint film is completely dry, the hardness of the cured paint film will be stable after a certain time, which can be considered that the paint film is completely dry So the method of measuring the hardness of paint film, such as pendulum hardness tester, can also be used to judge whether the paint film is completely dry Use the dry time recorder for detection, bk6 and BK10 automatic recorder, with independent action work, which allows you to test at different starting points A constant speed motor provides power to two paths and can have multiple speeds 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,
