I'm not sure about the amount of my own paint and latex paint At 10 a.m on December 28, Mr Xu found the home club of our newspaper and hoped that the reporter could help him calculate a material account "Please help me figure out how much paint my shoe cabinet and bookcase need and how much latex paint my wall needs." Mr Xu is prepared to come here He specially brings two drawings, namely the elevation of his own shoe cabinet and bookcase, which are annotated with the data of length, width and height Even the area of the wall and ceiling of his own house has been estimated in advance by Mr Xu The total area is 260 square meters Now, the reporter arranges his thoughts and lists the problems that Mr Xu needs to solve 1 The total area of ceiling and wall is 260 square meters How much emulsion paint is needed? 2 The self-made two door shoe cabinet with shutter shape, length, width and height are 0.9m, 0.3m and 1m respectively How much paint does it need? 3 The self-made bookcase is 4.4m long and 2.4m high, with a row of glass doors in the middle How much paint does the bookcase need to be painted? In order to give Mr Xu a more accurate answer, the reporter specially consulted Lin Yongsheng, general manager of the city Mantian Decoration Co., Ltd., and gave a detailed analysis and answer to the questions raised by Mr Xu According to Lin Yongsheng, the amount of latex paint used for ceiling and wall is about 10 square meters according to one brush In short, one tenth of a kilogram of emulsion paint needs to be used per square meter of wall surface The total area of the ceiling and wall of Mr Xu's house is 260 square meters It takes about 260 * 1 / 10 = 26 kg according to one brush 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 ways to calculate the amount of paint used in the self-made shoe cabinet Method 1: according to the number of panels used in the shoe cabinet According to the calculation of one brush, 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 kilogram of paint So how many panels are used for the painting part of the shoe cabinet? Let's assume that x panels are used, and the area of a panel is about 3 square meters Then, according to one brush, the paint consumption of this 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: calculate according to the panel area to be painted Take this self-made shoe cabinet for 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 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,
