Some businesses oil-to-water only stay in the propaganda enterprise deliberately vague concept

China Paint Online News InformationRecently, the Ministry of Industry and Information Technology and the Ministry of Finance jointly issued the Ministry of Industry and Information Technology Ministry of Finance on the issuance of key industries volatile organic matter reduction action plan notice, announced for the implementation of the "Made in China 2025" and "Air Pollution Prevention and Control Action Plan" To accelerate the implementation of the guidelines for the implementation of green manufacturing projects, promote the reduction of volatile organic matter (VOC) in key industries, raise the level of green development of industry, improve the quality of the atmospheric environment, improve the level of greening of manufacturing industry, the Ministry of Industry and Information Technology organized the preparation of the Action Plan for the Reduction of Volatile Organic Matter in Key Industries. According to the main objectives set out in the Plan, the proportion of low (none) VOC coating products will reach 60% by 2018.
, on the other hand, as far as the coatings industry itself is concerned, the attitude of the industry and the market towards water-based coatings has also underlying changed. Previously, although the industry's voice for water-based coatings is very high, but most of them only stay at the propaganda level, that is, in response to the "oil-to-water" call just to pursue industry trends in the people behind. Therefore, although has been hot and lively talk, but water-based paint technology and construction limitations so that many enterprises dare not put water-based paint into daily production, and ultimately to return to the main oil paint reality, after all, enterprises to make money to live. Over time, however, the situation has been subverted.
coating enterprises began to blur the concept of water-based paint
domestic paint enterprises including Jiabao, China Resources, three trees, Huilong, Hongchang, Kotian, Chenyang and other brands in recent years have introduced water-based paint, and in product development has made a technical breakthrough. So that the hardness, fullness, gloss, etc. of water-like paint have a qualitative change. In the water-based paint consumption experience of the market application, about the water paint construction of various construction techniques, solutions are also popular to dealers and oil workers, about the water-based paint environmental health concept has also formed a consensus among consumers. As a result, the promotion of water-based coatings throughout the country has been fully spread.
, the industry is gradually watering down the concept of "oily paint". At the 18th Guangzhou Construction Expo just past, art paint is the absolute protagonist of the paint area of the Expo. As a sub-area of the paint category, it is positioned as a high-end art wall material. Because the industry intentionally or unintentionally depaints behavior, people talk about art paint, people will ignore whether it is paint products or water-based paint products, but only focus on its artistic and diversity characteristics, and how it meets the personalized needs of consumers. Similarly, new wall materials such as mineral paint are also aimed at consumers with the image of high-end products in the coating sub-sector, and with the extension of the segmentation of the coating industry, people will only pay attention to the sub-sectors of the coating products, ignoring the properties of the products.
addition, coating enterprises in the release of new products, if it is water-based paint products, will be hyped and emphasized its water-based paint properties; If it is oily paint products, will only emphasize the function of new products and environmental characteristics, as far as possible to the image of healthy harmless products to close, try to blur the concept of oily paint products, and even avoid the appearance of paint in the text and publicity such words, the product of oily paint label as weak as possible.
the shortcomings of water-based paint what
1, water-based paint on the construction process and material surface cleanliness requirements are high, because the surface of water is large, dirt easy to make the coating film shrink hole;
2, water-based coatings against the strong mechanical force of the dispersion stability is poor, the flow rate in the pipeline changes sharply, the dispersed particles are compressed into solid particles, so that the coating film produces hemp points. The conveyor pipe is required to be in good shape and the pipe wall is free of defects.
3, water-based coatings on the coating equipment corrosion, the need to use anti-corrosion lining or stainless steel materials, equipment cost is high. Water-based coating corrosion of the conveyor pipe, metal dissolution, so that dispersed particles are dissected, coating film to produce hemp points, but also need to use stainless steel pipe.
4, baking water-based coatings on the construction environment conditions (temperature, humidity) requirements are more stringent, increased the input of temperature-regulating equipment, but also increased energy consumption.
5, the evaporation of water latent heat, baking energy consumption is large. Cathode electrophoresis coatings need to be baked at 180 degrees C; Latex coatings, on the other hand, are completely dry for a long time.
6, high boiling point of organic solvents, etc. in the baking produced a lot of oil smoke, condensation and drops on the surface of the coating film affect the appearance.
7, water-resistant paint has the problem of poor water resistance, so that the stability of the coating and tank fluid is poor, the water resistance of the coating film is poor. The medium of water-based coatings is generally in micro-alkaline (PH7.5 to pH8.5), the ester bonds in the resin are easy to hydrolysis and make the molecular chain degrade, affecting the stability of the coating and tank fluid, and the performance of the coating film.
how to distinguish the true and false
1, the real two-part water-like paint whether the main agent or curing agent after opening the can is basically no smell or only a very slight odor;
2, the real two-pack water-like paint is diluted with clean tap water, if you also need special diluents or alcohol-type substances to dilute it must not be;
3, two-part water-based paint is also non-hazardous chemicals and false two-parts are often flammable dangerous goods;
4, look at the environmental index: whether it contains benzene, heavy metals and high levels of VOC and other toxic substances.
Three differences between water-based paint and paint
the difference is one: concept
water-based paint, water-based thinner, no organic solvent coatings, no benzene, formaldehyde, xylene, free TDI and other harmful substances and heavy metals, non-toxic non-irritating odor, do not pollute the environment, harmless to human body.
oily paint, organic solvent as a thinner, which contains benzene, formaldehyde, xylene, free TDI and other harmful substances.
is a chemical mixture coating that can be firmly covered on the surface of May Day, which can play both a protective and decorative role.
two: the essence
water-like paint thinner is water, and water and oily paint is incompatible, if the water and oily paint mixed together will appear layering phenomenon; The thinner of oily paint is an organic solvent, so there is no layering phenomenon when oily paint is mixed with organic solvent as a thinner.
three: characteristics
water-resistant paint, crystal clear, flexibility is very good, with wear-resistant, yellow-resistant, water-resistant, fast drying, simple construction and other advantages; Suitable for wood, plastic, metal, glass and other materials.
oily paint, belongs to viscous pigments, easy to burn without dry, insoluble in water, soluble in benzene, alcohol, aldehyde, ether and other organic solvents, soluble in kerosene, diesel, gasoline and so on.
