Coating process: Determination of coating density

Core tip: density: the amount of substance contained in unit volume, expressed in ɡ / ml Rho =m/v Where ρ - density, μ / ml; M - mass, ɡ; V - volume, ml The density of the coating largely depends on the density of the pigments and fillers used, and is related to the volume concentration of the pigments and fillers, the density of the base materials and solvents in the formula Generally, gold is used Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: density: the amount of substance contained in unit volume, expressed in ɡ / ml ρ = ρ - density, ρ / ml; m - mass, ρ; V - volume, ml The density of coating depends on the density of pigment and filler to a great extent, and is related to the volume concentration of pigment and filler, the density of base material and solvent in the formula Generally, the density of metal oxide used as pigment and filler is higher than that of inorganic compound and organic compound There are many kinds and methods to test the density of coatings At present, the laboratory has made a 1130 type specific gravity cup of byk100 ml 1 Wash the specific gravity cup with proper solution and make sure it is completely dry After weighing the specific gravity cup, weigh it again for 15 minutes The weight difference between the two weighings shall not exceed 0.02 μ M 2 Weigh the specific gravity cup and its cover: M 1 (unit: G) 3 After mixing the substances to be measured evenly, pour them into the specific gravity cup to avoid bubbles Close the cover so that the excess substances to be measured overflow from the holes on the cover After wiping, weigh: M 2 (unit: G) 4 Coating specific gravity (density) = (m2-m1) / 100 (unit: g / ml) 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,
