    Core tip: paint is one of the eight categories of building materials Due to the large construction area, once the material itself is polluted, it will cause great damage to the health of family members Therefore, safety and environmental protection are more and more important when purchasing paint Of course, in the actual operation, we should pay attention to the scientific calculation of the amount of paint needed to avoid insufficient use of paint or a large number of surplus The lower the four environmental protection indicators, the better the clean flavor paint, bamboo charcoal paint, aloe paint, formaldehyde resistant paint, diatom mud paint, children's paint With more and more decoration accidents happening, many decoration owners Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: paint is "building materials eight categories" in a large category Due to the large construction area, once the material itself is polluted, it will cause great damage to the health of family members Therefore, safety and environmental protection are more and more important when purchasing paint Of course, in the actual operation, we should pay attention to the scientific calculation of the amount of paint needed to avoid insufficient use of paint or a large number of surplus The lower the four environmental protection indicators, the better the clean flavor paint, bamboo charcoal paint, aloe paint, formaldehyde resistant paint, diatom mud paint, children's paint With more and more decoration safety accidents, many decoration owners began to be vigilant: home decoration must choose the safest and most environmentally friendly materials However, there are various kinds of paint products on the market Especially in recent years, the main "environmental protection" and "safety" paints emerge in an endless stream, dazzling people The key to determine the quality of paint is the content of VOC, benzene, formaldehyde and heavy metal According to the national regulations on the limit of harmful substances in interior wall coating of interior decoration materials (GB18582-2008), the qualified wall coating shall meet the following standards: VOC ≤ 120g / L; benzene, toluene, ethylbenzene, xylene total ≤ 300mg / kg; free formaldehyde ≤ 100mg / kg; lead Pb ≤ 90mg / kg, cadmium Cd ≤ 75mg / kg, chromium Dr ≤ 60mg / kg, mercury Hg ≤ 60mg / kg Generally speaking, the lower the data, the better For example, the VOC content of some paint products is as low as 30-40g / L, and the free formaldehyde is less than 10 times of the standard, which means that the environmental protection of these products is better However, these data are not compulsory to be marked on the paint bucket The main business owner needs to ask the brand or the store for relevant documents and quality inspection reports to understand the environmental protection data of the product At the same time, the purchase of paint products can also depend on whether the products have Chinese environmental signs and 3C certification The products should also be clearly marked with company name, address, production date, batch number, shelf life, executive standard, contact number and other information Brushing area = using area × 3 besides environmental protection and safety, how much paint to buy is also a headache Buying too much is easy to cause waste, but buying too little does not mean that supplementary purchase can be solved For some paints as like as two peas, it is often difficult to replace the original paint with the same amount of color when the quantity is insufficient This leads to wall painting color difference, greatly affecting the beauty of the wall Therefore, before the construction, the paint would rather buy more than less, especially the color matching paint According to a calculation method in the industry, the painting area = room use area × 3 (or = building area × 2), and 5L paint per barrel can paint 60-70m2 wall surface (once) Generally speaking, the wall needs to be painted with one primer and two finishing coats According to this formula, the space with a building area of 100 square meters needs about 30L of top coat and 15L of primer When purchasing paint, it is also necessary to check whether there is any caking, discoloration and other problems when the paint is opened If there is any problem beyond the warranty period, it is necessary to replace it in time to avoid the use of inferior paint affecting the normal use after occupancy They can also be used to replace the paint for fear of environmental protection and safety risks? The effect of the paint is single and not beautiful enough? There are many alternative wall materials for the paint on the market Wallpaper is the most common one, in addition to beautiful patterns, decorative enough, there are moisture-proof, negative oxygen ions and other functions, which can reduce indoor air pollution to a certain extent However, when choosing wallpaper, we should pay attention to environmental protection and natural glue, because glue is the biggest source of wallpaper pollution In addition, there are wall cloth that can be ironed on the wall through high temperature and diatom mud wall material that can absorb harmful gases, which are the pioneers of environmental protection wall materials at present 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,
