Coating knowledge: construction skills of waterborne wood paint

Core tip: with the development of national economy and the improvement of living standards, people's awareness of environmental protection is becoming stronger and stronger At the same time, the legislation and regulations of government departments on environmental protection and safety will be more and more strict, the indicators will be higher and higher, and the process will be faster and faster The environmental protection of solvent based wood coatings will attract more and more attention Water based coatings are non-toxic, odorless and volatile There are few organic matters in hair, which are non combustible and non explosive Its environmental protection superiority has been generally recognized and accepted by people The development of waterborne wood paint will be faster and faster, which will become the main direction of wood paint development in the future 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 Home of coatings news: with the development of national economy, the improvement of living standards, people's environmental protection At the same time, the legislation and regulations of the government departments on environmental protection and safety will be more and more strict, the index will be higher and higher, and the process will be faster and faster The environmental protection of solvent based wood coatings will attract more and more attention The water-based coatings have the characteristics of non-toxic, odorless, volatile organic matter is very few, non combustible, non explosive and high safety, and its environmental protection is superior The property has been generally recognized and accepted by people, and the development of waterborne wood paint will be faster and faster, which will become the main direction of wood paint development in the future At present, although the development of waterborne wood paint is very fast, its application rate is still very low There are many factors restricting the development of waterborne wood paint The construction difficulty is one of the important factors As we all know, waterborne wood paint is constructed after being diluted with water Due to the large surface tension and poor wettability of water, the construction is difficult Mastering some skills in the construction will be beneficial to the use and promotion of waterborne wood paint 1 Waterborne wood paint is greatly affected by the environmental humidity, too low humidity, too fast drying, affecting the leveling, high humidity, slow drying, and easy to whiten; generally, the appropriate humidity is 40-80%, and the appropriate temperature is 5-35 ℃; 2 The white body treatment and polishing before painting must be thorough, and there should be no offset oil and other impurities, so as to avoid affecting the adhesion and color uniformity; 3 Wood There are many burrs on the surface which are difficult to polish and remove, which will affect the next construction The wood surface can be wetted with water or water-based sealing primer and then polished, so the burrs will be more easily removed; 4 The wood conduit contains impurities such as tannic acid and grease, which can be cleaned with water, and then sealed with water-based sealing primer; the wood with high grease content must be degreased; 5 The construction viscosity of water-based wood paint should be reasonable, generally 20-35 seconds in Iwata No.2 cup, too thick affects the leveling, and too thin is prone to sagging and blooming; 6 The water-based color is generally slow to dry, which can be rubbed or sprayed, but the next process can only be carried out after the water-based color is baked and dried completely; 7 When repairing the color with water color surface, it is not allowed to spray too wet, but can spray a little dry, otherwise it is easy to blossom; 8 The construction of water-based wood paint should be uniform, and it should not be too thick at one time, and there should be a certain drying time between each time, generally more than 2 hours, otherwise it is easy to appear white In the construction and application of waterborne wood paint, the suppliers of raw materials, paint factories and furniture factories have done a lot of work, done a lot of tests, and made great progress in formula adjustment and application research Among them, zhanchen water-based wood paint has good performance and rich experience in construction Zhanchen water-based wood paint has been accepted by many furniture factories and oil workers 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,
