    Core tip: the wear resistance of the floor paint coating refers to the resistance of the paint film to friction after drying, that is, the ability to maintain the performance of the paint film in case of mechanical damage Wear resistance is one of the mechanical properties of coatings, especially for those coatings which are often subject to mechanical wear in the process of application, such as aircraft, automobile, road signs, floor, deck and other coatings, more important quality control indicators The national standard gb1768-89 (79) specifies a method for determining the performance of paint film by using the paint film abrasion tester It is expressed in terms of weight loss of paint film after specified grinding times under a certain load 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 Paint Home News: the wear resistance of floor paint coating refers to the resistance of the paint film to friction after drying, that is, the ability to maintain the performance of the paint film in case of mechanical damage Wear resistance is one of the mechanical properties of coatings, especially for those coatings which are often subject to mechanical wear in the process of application, such as aircraft, automobile, road signs, floor, deck and other coatings, more important quality control indicators The national standard gb1768-89 (79) stipulates the method of determining the performance of paint film by using the wear-resistant instrument of paint film It is expressed in terms of weight loss of paint film after specified grinding times under certain load, unit: G (g) Steps: 1 Put the sample book on the special round glass plate, and generally paint twice, with an interval of 24 hours 2 Fix the test plate on the working plate of the wear-resistant instrument, add the specified load on the pressure arm, put down the vacuum nozzle, and adjust it to the sample 1-1.5mm 3 Turn on the switch, grind the sample plate for 50R (circle) first, so as to form a relatively flat surface 4 Wipe off the floating debris with a brush, and weigh it for the first time 5 Adjust the counter according to the product standard for test When the specified number of wear-resistant revolution is reached, the line stops 6 Take out the sample, wipe off the floating debris and weigh it for a second time The difference between the front and back quality is the weight loss of the paint film Two parallel tests are required, and the error of each value is not more than 7%, and the average value is taken as the result For example, the requirements for the abrasion resistance of the epoxy mortar floor are: the weight of the arm is 750g, the abrasion resistance is 500r, and the quality difference between the front and rear paint film is not more than 0.02g The wear resistance is closely related to the hardness and adhesion of the coating Generally, it has strong adhesion, high hardness and good wear resistance But we can't judge the wear resistance completely according to these two properties The wear resistance of coating is also related to the type of substrate and surface treatment 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,
