Water-based paint refers to the general designation of paint with water as solvent, such as latex paint on the wall surface, water-based wood paint that can be applied to the construction of wood, etc. These are all water-based paints. To put it bluntly, the paint that can add water to form a homogeneous and miscible liquid is water-based paint. The difference between water-based paint and wood paint: 2. Environmental protection ordinary wood paint uses special thinner to adjust the viscosity of the paint. Generally, the thinner will contain a certain amount of formaldehyde, benzene and other harmful substances; while water-based paint uses water as diluent. Of course, there are no harmful substances such as formaldehyde and benzene, so it is more environmentally friendly. The difference between water-based paint and wood paint: 3. Odor Traditional oil-based paint is diluted with natural water and other diluents, which will emit more stimulating gases and are all strong carcinogens. Water-based paint is diluted with water, that is, ordinary drinking water, as diluent, and generally there will be no stimulating smell drifting away. The difference between water-based paint and wood paint: 4. Price At present, the cost of water-based paint is relatively high, while the cost of ordinary oil-based wood paint is lower than that of water-based wood paint, and the price is relatively lower. There is still a big difference between the difference between water-based paint and wood paint, so it is best to choose water-based wood paint when choosing wood paint, and the environmental protection degree of water-based paint should be relatively high.
DetailsPVC will be PU instead of environmental protection artificial leather into the development trend

With the progress of economic development, leather plays an increasingly important role in people's daily life, and cheap and high-quality artificial leather has become the most loved product. Now the artificial leather industry has developed into one of the important industries in the daily consumer products industry. At present, the dominant position of artificial leather is PVC artificial leather, but due to the relatively poor permeability and moisture absorption of PVC artificial leather, the development in recent years has been subject to certain restrictions, PU leather gradually replace the traditional PVC artificial leather. PVC will be PU to replace environmentally friendly artificial leather into the development trend of the beginning, the main raw material of artificial leather is PVC, but with the continuous progress of science and technology, people found that PVC in the use of the process there are many big problems, pollution is also very serious, especially after the sun exposure will produce toxic gases, leading to cancer. Although the state has not yet banned PVC products, but with the gradual increase in the concept of environmental protection, the level of technology continues to improve, many domestic artificial leather enterprises aware of this problem, and continue to improve technology, to replace the PVC PU appeared. Especially in recent years, the development of PVC has been restricted more and more, and the number and scale of PVC plants have been much worse than before. PU leather is more environmentally friendly than PVC. At present, all the use of PVC material, PU can become its substitute. Many domestic manufacturers have noticed the application of PU leather in leather, and the use of advanced technology has greatly reduced its production costs and formed a complete industrial chain. It is understood that there are still many products still use PVC, but these companies have begun to slowly transition to the production of PU leather. With the acceleration of the integration process of the international market, the advantages of high quality and low pollution of PU leather will become more and more obvious, and various high-performance PU leather products will continue to be introduced to the market. Although PU products will have an adjusted growth period, it is the inevitable trend of the development of the synthetic leather industry to replace PVC products in the mainstream products. However, most people refer to the products of these two materials as artificial leather. Although PVC and PU are polyvinyl chloride as the main raw materials, the manufacturing processes of these two products are different. The price of PU leather is more than twice as high as that of PVC leather, and the price of PU leather with certain special requirements is 2-3 times higher than that of PVC leather. Even so, but PVC over the years of competition, development, and now the profit space has been very narrow, some varieties, only a few cents per meter or even a few cents of the benefit space. In fact, in theory, as the industry continues to upgrade, technology continues to improve, PU in the future should be more price advantage than PVC. In the service life, the general PU leather can only be scrapped 4-5 times; PVC leather has a long service life, so the current artificial leather market is still based on PVC, after all, new products need a certain buffer time to eliminate old products.
