Coating knowledge: calculation method of the amount of paint and emulsion paint

Core tip: the paint is mainly divided into wall paint and wood paint, so the following calculation formula is divided into the calculation of the amount of wall paint emulsion paint, the amount of home-made wood furniture primer and the amount of home-made wood furniture finish A 120 square meter new house 1 The total area of the ceiling and wall is 260 square meters, how much emulsion paint is needed? 2 The two door shoe cabinets with self-made louver shape are 0.9 meters long, 0.3 meters wide and 1 meter high respectively, how much paint is needed? 3 The self-made bookcase is 4.4 meters long and 2.4 meters high, with a row of glass doors in the middle How much paint does this bookcase need to be brushed off? The amount of glue paint for ceiling and wall emulsion Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: paint is mainly divided into wall paint and wood paint, so the following calculation formula is divided into the calculation of the amount of wall paint emulsion paint, the amount of home-made wood furniture primer and the amount of home-made wood furniture finish A 120 square meter new house 1 The total area of the ceiling and wall is 260 square meters, how much emulsion paint is needed? 2 The two door shoe cabinets with self-made louver shape are 0.9 meters long, 0.3 meters wide and 1 meter high respectively, how much paint is needed? 3 The self-made bookcase is 4.4 meters long and 2.4 meters high, with a row of glass doors in the middle How much paint does this bookcase need to brush off? The amount of latex paint used for ceiling and wall is calculated by brushing once One kilogram of latex paint can brush about 10 square meters of wall In short, one tenth of a kilogram of emulsion paint needs to be used per square meter of wall surface The total area of ceiling and wall is 260 square meters It takes about 260 * 1 / 10 = 26 kg if it is painted once Generally speaking, the ceiling and wall need to be painted twice, so the amount of emulsion paint required for Mr Xu to brush the ceiling and wall is about 26 * 2 = 52 kg There are two methods to calculate the paint consumption of the self-made shoe cabinet: one is to calculate the paint consumption according to the number of panels used in the shoe cabinet, one kilogram of paint can brush about 15 square meters of panels, that is to say, each square meter of panel needs to use 1 / 15 kg of paint How many panels are used for the parts of the shoe cabinet that need to be painted? Let's assume that X panels are used, and the area of one panel is about 3 square meters According to the calculation of brushing, the paint consumption of the shoe cabinet is about 1/15*3*X kg According to the calculation of "three bottoms and two sides", the amount of primer and finishing coat shall be multiplied by three times and two times respectively, i.e 1 / 15 * 3 * x * 3kg and 1 / 15 * 3 * x * 2kg Method 2: according to the calculation of the panel area to be painted, take this self-made shoe cabinet as an example Except for the back and bottom, the top, front and both sides need to be painted The length, width and height of this shoe cabinet are 0.9m, 0.3m and 1m respectively Then, the area of the top, front and two sides are 0.9 * 0.3m2, 0.9 * 1m2, 0.3 * 1 * 2M2, namely 0.27m2, 0.9m2 and 0.6m2 Because the two doors of the shoe cabinet are in the shape of shutters, the paint consumption is relatively more The paint consumption of these two doors must be multiplied by a factor of 1.2, that is to say, brushing these two doors is equal to brushing 0.9 * 1.2 square meters of panels According to the calculation of one brush, the paint consumption of this shoe cabinet is 1 / 15 * (0.27 + 0.9 * 1.2 + 0.6) = 0.13kg According to the calculation of "three bottoms and two sides", the amount of primer and finish required for this shoe cabinet is 0.39kg and 0.26kg respectively The amount of paint used for the self-made bookcase is 4.4m long and 2.4m high In addition to the upper and lower two rows of doors, there is also the inside of the bookcase that can be seen through the glass We can first calculate the area of the upper and lower rows of cabinet doors, 4.4 * (2.4-1.2) = 5.28m2 Although the middle row is glass, the corners of the glass and the inside of the cabinet visible through the glass need to be painted, and the amount is relatively large, which is about 4 times of the glass area, that is, 4.4 * 1.2 * 4 = 21.12m2 Therefore, according to the calculation of one brush, the paint consumption of this self-made bookcase is about 1 / 15 * (5.28 + 21.12) = 1.76kg According to the calculation of "three bottoms and two sides", the amount of primer and finish is 5.28kg and 3.52kg respectively There are two formulas about the amount of emulsion paint For your reference, the amount of emulsion paint on the wall = 1 / 10 * the total area of the wall * 2 (brushing twice) the amount of furniture primer = 1 / 15 * the area to be brushed * 3 (brushing three times) the amount of furniture finish = 1 / 15 * the area to be brushed * 2 (brushing twice) the home of the paint is focused on the paint, diatom mud, paint coating, coating technology, News and information of fire retardant coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
