Common knowledge of coating: what are the problems of external wall putty products in China and its future development direction

Core tip: the development prospect of architectural coatings in China is broad, the development speed is unprecedented, the use of exterior wall coatings is increasing year by year, followed by the use of supporting exterior wall putty is also increasing year by year However, in the development of putty, there are still many problems, mainly as follows: Although there are existing standards to be followed, the production and use of external wall putty are not standardized, the putty market is in a price war, and the market products are mixed; the quality of the construction team is low, so it is difficult to carry out the construction according to the construction procedures proposed by the manufacturer, and it is difficult to accept the new products; recognition of the important role of external wall putty Knowledge needs to be further improved 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 Home of coatings news: the development prospect of architectural coatings in China is broad, and the development speed is unprecedented The use of external wall coatings is increasing year by year, followed by the use of supporting external wall putty is also increasing year by year However, in the development of putty, there are still many problems, mainly as follows: Although there are existing standards to be followed, the production and use of external wall putty are not standardized, the putty market is in a price war, and the market products are mixed; the quality of the construction team is low, so it is difficult to carry out the construction according to the construction procedures proposed by the manufacturer, and it is difficult to accept the new products; recognition of the important role of external wall putty Knowledge needs to be further improved; the R & D level of putty product varieties, constructability and construction methods is not enough, far lower than the R & D level of coating; there is a lack of excellent products with good cost performance and can be quickly accepted by the market The putty for exterior wall should be developed in the direction of high performance, functionalization and serialization High performance refers to the ideal bond strength and dynamic cracking resistance Only when they are relatively unified, can the old and difficult problems of wall cracks be solved or alleviated, and the high quality of paint finish be guaranteed In addition, due to the large quantity and wide range of external wall putty, it is necessary to have a good price performance ratio to be accepted by the market, otherwise, no matter how good the performance is, the price is too high, it is also difficult to popularize External wall putty is not only used for leveling the wall base of new buildings, but also used for renovation and renovation of old buildings Different base layers should have different requirements, such as the old clay brick, the old tile mosaic, the old wall with serious cracks, the external insulation system of external wall, etc The same putty cannot be used Therefore, it is necessary to further refine the putty products on the basis of general leveling putty, functionalize and serialize the putty products, such as endowing putty products with flexibility, elasticity, high elasticity, cracking resistance, heat preservation, waterproof, mildew resistance and other properties, so as to meet the needs of the rapid development of the construction industry and promote the rapid and healthy development of architectural coatings 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,
