All construction coatings have passed ISO9001 Paint Home News: when it comes to paint, most people may be able to say one, two, three, but when it comes to water paint, a considerable number of people may not understand it It doesn't matter Next, Xiaobian will learn about water paint together After reading the following article, you will have the answer in mind I brief introduction of water paint water paint is actually called water paint, which is a kind of water paint with water as diluent and no organic solvent, no benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metal, non-toxic and non irritating smell, harmless to human body, no pollution to the environment and full film Paint is a kind of chemical compound paint that can cover the surface of objects firmly, protect, decorate, mark and other special purposes The water paint is crystal clear, flexible and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, fast drying and convenient use Can be used in: wood, metal, plastic, glass, building surface and other materials The paint is viscous oil pigment, which is inflammable when not dry, insoluble in water, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene, alkane, soluble in gasoline, kerosene and diesel oil Regardless of the type or shape of paint, it is composed of three basic substances: film-forming substance, secondary film-forming substance and auxiliary film-forming substance How about water paint? When it comes to water paint, many people may have this kind of question We will learn about the advantages and disadvantages of the water paint together with Xiaobian, so that we can know well The advantages of waterborne paint: 1 Using water as solvent can save a lot of resources; eliminate the fire risk during construction; reduce the air pollution; only use a small amount of low toxic alcohol ether organic solvent to improve the working environment 2 The electrophoretic coating is even and flat The inner cavity, weld, edge and edge can be coated with a certain thickness of coating, which has good protection; the electrophoresis coating has the best corrosion resistance, and the salt spray resistance of the thick film cathodic electrophoresis coating can reach up to 1200h 3 Coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvent 4 The water-based coating can be applied directly on the wet surface and in the wet environment; it has good adaptability to the material surface and strong adhesion of the coating Disadvantages of water-based paint: 1 The water-based paint has high requirements for construction process and material surface cleanliness Due to the large surface tension of water, dirt is easy to cause shrinkage of the film 2 The organic cosolvent with high boiling point produces a lot of oil smoke during baking, which drips on the surface of the coating after condensation and affects the appearance 3 The water-based coating is highly corrosive to the coating equipment, which requires anti-corrosion lining or stainless steel materials, so the equipment cost is high Stainless steel pipe is also required for corrosion and metal dissolution of water-based coating to transmission pipeline, which makes dispersed particles precipitate and coating produces pockmarks 4 The baking type water-based coating has strict requirements on the construction environment (temperature and humidity), which increases the input of temperature and humidity regulating equipment and energy consumption 5 The evaporation latent heat of water is large, and the baking energy consumption is large The cathodic electrophoretic coating needs to be baked at 180 ℃, while the latex coating has a long drying time 6 The dispersion stability of water-based coating against strong mechanical force is poor When the flow velocity in the pipeline changes rapidly, the dispersed particles are compressed into solid particles, making the coating produce pockmarks It is required that the shape of the conveying pipe is good and the pipe wall is free of defects What are the differences between water paint and paint? Water paint and paint belong to two categories of paint Paint may be one of the most popular, because we generally call paint as paint, but we have never noticed that paint is one of the paints, so you may have little understanding of the difference between water paint and paint It's OK to decorate here in Wuxi Wang Xiaobian will tell you For water paint, the diluent it uses is water, and the diluent of paint must not use water, because paint and water are incompatible, there will be layering phenomenon, that is to say, when water is added to paint as diluent, there will be two dispersed phases, then what is the diluent used for paint, of course, it is also similar to its organic solvent The principle of similarity compatibility is embodied here The difference of diluent is the biggest essence of the difference between water paint and paint 4 The difference between water paint and emulsion paint Any paint using water as solvent or dispersion medium can be called water-based paint The water-based coating includes water-soluble coating, water diluting coating and water dispersing coating (emulsion coating) Latex paint, also known as synthetic resin emulsion paint, is a kind of organic coatings, which is a kind of waterborne coating made of synthetic resin emulsion, which is made up of pigments, fillers and various auxiliaries Emulsion paint is only one kind of water-based paint, which has a wider range, including metal paint, wood paint, etc 5 Is the price of water paint expensive? The price difference between oil paint and water paint is not much Water paint is a little more expensive, but water paint is environmentally friendly, which is incomparable Now people pay more and more attention to environmental protection, and more and more people choose water paint Generally, the price of water paint is about 120 yuan to 350 yuan Affordable point smell to send out faster or use a famous brand such as Nippon The price is OK It is also easier to construct Vi when it comes to the introduction of water paint brand, we all know that it has been deeply rooted in the hearts of the people How much do you know about water-based paint? Here, Wuxi decoration net will briefly introduce the water-based paint and the brand ranking of water-based paint, so that you can understand this kind of products during decoration 1 Nippon, a world-famous paint manufacturer and Singapore brand, is one of the few manufacturers in the world that can provide all paint products Its high-quality products have won the trust and praise of global users 2 Shark and shark, the development concept of "environmental protection creates health", strive to create an international environment-friendly and healthy home for consumers and contribute to China's healthy home industry 3 Huarun, for a long time, has adhered to the core communication idea of "real expert in the paint industry" The image of the expert has been successfully shaped, forming a unique landscape and growing into a leading enterprise of local paint brands 4 3A environmental protection paint, 3A environmental protection paint production base is located in Shunde, Guangdong Province, the "hometown of paint" It is not only the leading advocate of green environmental protection paint in the industry, but also the executor of the concept of "whole process environmental protection" and "pure environmental protection" for decades 5 Maydo, the artist, has positioned himself as "healthy paint", which has formed the interior and exterior walls Latex paint, wood paint, furniture paint, texture paint, industrial paint and other product lines, its health Star clear aldehyde, shine 1 + 1, clean taste home, gold all in one Bauhinia Bauhinia Bauhinia, Bauhinia paint was founded in 1982 It is one of the three core businesses of Yeshi Chemical Group Co., Ltd., a Hong Kong listed company At present, its production and administrative bases include seven locations in Shanghai, Chengdu, Shenzhen, Huiyang, Shantou, Dongguan and Tongxiang 7 Carpoly, Carpoly paint is a relatively ideal enterprise In the period of the dispute over the local and foreign paint brands, it has taken a clear and distinctive position earlier and played a significant role in the rise of domestic paint enterprises 8 Dulux, the predecessor of Dulux ICI Group, brunermon-d & Co, is a famous manufacturer of soda ash and fertilizer In 1898, the company sent a representative to visit China and considered marketing products there Mr Edward selb-y little was hired as the first general manager of the company in China 9 Giraffe paint, a brand of Chinese paint, was founded in 1932 and has a history of more than 75 years It is one of the earliest paint companies in China It has established a strong competitive advantage in the fields of interior and exterior wall architectural coatings, wood coatings, non-toxic industrial coatings and heavy-duty anti-corrosion coatings 10 Taiho, Dabao paint is a paint brand from Taiwan Its products cover wood paint, water-based paint, building paint, metal paint, etc., including "jiewuli" antibacterial wall paint, "yitaili" clean flavor wall paint, environmental protection heat insulation, etc With several years of development, it has a high popularity among consumers 7 Analysis of purchasing skills of water-based paint 1 From the appearance, water-based paint is generally marked with the words of water-based or water-soluble, and it can be diluted with clear water, as well as relevant technical parameters and standards will be indicated in the instructions The 2 is to look at the color According to the current water-based technology, waterborne lacquer is usually produced by emulsion technology or dispersion technology Most commonly used emulsions are mostly acrylic, and water-based colorless paints are usually milky white or translucent, light creamy or light yellow, while ordinary varnish is often transparent 3 It is to smell The biggest and most obvious feature of water-based wood paint different from solvent based wood paint is the smell: the smell of water-based paint is very small, while ordinary paint has a strong irritant smell 4 Product test report For normal waterborne paint products in the general market, before they are put on the market, they must pass the sampling test of authoritative testing institutions to judge whether the VOC content of their products really meets the requirements of the national mandatory standards Therefore, when purchasing waterborne paint, consumers can require manufacturers or distributors to provide product test reports of CMA qualified testing agencies But the fake water-based paint can not provide the authoritative test report at all 5 In terms of product certification, at present, the most authoritative product ring in China
