Paint knowledge | common coating terms and explanation

Surface drying time: 1 The time required for a certain thickness of wet paint film to change from liquid to solid under the specified drying conditions, but the surface is believed to be liquid 2 2 Hard drying time under the specified drying conditions, the time from the application of a certain thickness of liquid paint film to the formation of solid paint film 3 Transparency the ability of matter to pass through light Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: 1 Surface drying time under specified drying conditions, a certain thickness of wet paint film, the time required for the surface to change from liquid to solid, but it is believed to be liquid 2 Hard drying time the time required to form a solid paint film from a certain thickness of liquid paint film to the specified drying conditions 3 Transparency the ability of matter to pass through light Transparency can show that varnish, paint and diluent contain mechanical impurities and turbidity 4 Density the mass per unit volume of an object at a specified humidity The common unit is kilogram per cubic meter (kg / m3), gram per cubic centimeter (g / cm3) 6 Solid content non volatile matter content: the content of nonvolatile matter contained in solidsco ntent coating It is generally expressed by the percentage of the mass of non-volatile matter, or by the percentage of volume 7 Fineness of grind a measure of the dispersion of pigments and physical pigments in fineness of grind coating That is, under the specified conditions, the reading obtained on the standard fineness meter, which indicates the depth of a groove in the fineness meter, generally in microns (μ m) 8 Storage stability under the specified conditions, the degree to which the coating product resists the performance changes such as peculiar smell, consistency, skinning, coarseness, sinking, caking and so on that may occur after storage 9 Compatibility the ability of one product to mix with another without adverse consequences (such as precipitation, agglomeration, thickening, etc.) 10 Hiding power: the ability of hidingpower color paint to eliminate the color difference on the substrate 11 The difficulty of construction of application nproperty coating Note: the coating has good workability, generally refers to the coating is easy to apply (brush, spray, dip, etc.), good leveling, no sagging, wrinkling, shrinkage, color penetration, undercut; moderate dryness, easy grinding, good repainting, and low requirements for construction environment conditions 12 Recoatability the difficulty and effect of multi-layer coating with the same coating 13 Film thickness the measurement of film thickness, generally expressed in microns (μ m) 14 An optical property of a glossy surface expressed by its ability to reflect light 15 Adhesion the firmness of the bond between the adhesion film and the coated surface (through physical and chemical action) The coated surface can be either bare or painted 16 Hardness paint film's resistance to mechanical forces such as collision, indentation and scratch 17 The ability of flexible paint film to form with its substrate without damage 18 Resistance of abrasio nresistance film to friction 19 After polishing (dry or wet grinding) with pumice, sandpaper and other materials, the abrasive rubbingproperty paint film or putty layer will produce a smooth matte surface 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,
