Coating technology: Determination of viscosity of paint

Core tip: viscosity: it is a measure of the resistance of a liquid when it moves on another part, and it is a property of the liquid that hinders its relative flow The viscosity can reflect the molecular weight of the polymer in the paint base, and the thickness of the film can be controlled by the viscosity during the spraying process to improve the appearance of the film Before the test, mix the paint evenly, and then dip the viscosity cup into the paint by holding the handle with your hand When there is no bubble in the cup, quickly lift the viscosity cup out of the page, and the stopwatch starts to count When the paint does not flow out continuously, stop the stopwatch At this time, the stopwatch shows Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: viscosity: it is a measure of the resistance of a liquid when it moves on another part, and it is a characteristic of the liquid's internal obstruction of its relative flow The viscosity can reflect the molecular weight of the polymer in the paint base During the spraying process, the thickness of the film can be controlled by viscosity to improve the appearance of the film Before testing, paint Stir evenly, and then dip the viscosity cup into the paint by hand When there is no bubble in the cup, quickly lift the viscosity cup out of the page The stopwatch starts to count When the paint does not flow out continuously, stop the stopwatch At this time, the time (s) displayed by the stopwatch is the viscosity of the paint under this test condition The difference of conjunctions test shall not be greater than 3% of the average value, and the test temperature shall be 23 ℃ ± 1 ℃ 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,
