    Global Coatings Network News:
    The new environmental protection law that came into effect on January 1 last year not only made people feel the power of the "strictest system", but also because the environmental protection law is positioned as a basic law in the field of environmental protection, without specific regulations.
    Sexual content, and some people think it is a "toothless tiger.
    "
    In the past year, legislative actions related to environmental protection have been very frequent.
    According to incomplete statistics, my country has formulated and issued as many as 85 relevant laws, regulations, rules, and normative documents: except for those approved by the Standing Committee of the National People’s Congress.
    In addition to the air pollution prevention and control law, the State Council, the General Office of the State Council, the Ministry of Environmental Protection, the National Development and Reform Commission, the Ministry of Land and Resources, the Ministry of Water Resources, and the Ministry of Agriculture have issued a total of 84 departmental regulations and normative documents.
    All of these have allowed the new environmental protection law to "grow teeth", forcing some furniture companies that were originally major polluters to adopt more environmentally friendly water-based paint (also known as "water-based paint") to produce furniture.
      


    Global Coatings Network News: 


    Robot water-based electrostatic spraying becomes a hot spot


    The reporter found that the enforcement of environmental protection laws and regulations has continued to increase, which has forced many furniture companies to start using water-based paint this year.
    A well-known furniture company in Foshan said that it will definitely install a water-based paint production line this year, because the pressure of environmental regulations has forced them to start an attempt in this regard.
    The increasingly mature production technology is also dispelling many manufacturers' concerns about the increased cost of using water-based paint.


    A well-known brand paint manufacturer is responsible for introducing that electrostatic spraying is a new technology of modern spraying.
    It makes the atomized paint particles negatively charged in the DC high-voltage electric field, and then under the action of the electrostatic field, they are oriented and adsorbed on The surface of the object to be sprayed with positive charge is deposited into a uniform and firm paint film.
    Compared with ordinary brushing and spraying, electrostatic spraying not only has full paint film, strong adhesion and good decoration, but also greatly improves the utilization rate of paint.
    Generally, the utilization rate of manual spray paint is 30%-40%, and the utilization rate of electrostatic spray paint It can reach 70%-80%, which greatly reduces paint mist scattering, reduces environmental pollution, improves working conditions, and ensures the health of paint workers.


    According to reports, in addition to saving paint consumption, robot electrostatic spraying also greatly improves production efficiency.
    Manual spraying is not suitable for the operation of large-area products.
    Electrostatic spraying can completely carry out large-area operations.
    As long as multiple electrostatic spray guns are installed at the same time, spraying can be greatly shortened and spraying efficiency is improved.


    Liu Delu, Purchasing Director of Shenzhen Seven Color Life Furniture Co.
    , Ltd.
    , said that water-based paint is basically mature in terms of operation, but most furniture companies still use traditional spraying, curtain coating or dip coating processes, which is not only inefficient, but also wasteful of paint.
    And good coating companies will carry out process transformation and upgrades in a targeted manner according to the coating needs of furniture companies, and replace labor with more environmentally friendly mechanized coatings such as UV coating and water-based coating, which greatly improves the profit margin of furniture companies.


    Water-based coating is promising


    According to reports, in order to improve production efficiency and reduce costs, many furniture companies have begun to try "machine substitution", and the development of highly automated "unmanned factories" is accelerating.
    In some of the more famous furniture factories, there is basically no dust, no smell of paint, no ear-piercing sound of electric saws, the scent of birds and flowers, the shade of green trees, all kinds of large-scale equipment are neatly arranged, and all kinds of furniture and materials.
    The stacking is orderly and enters the systematic management.
    "Machine replacement" not only reduces labor intensity and improves the production environment, but also reduces the turnover rate of the factory.
    High-efficiency painting also gives furniture manufacturers more room for development.


    In order to meet the changing needs of "machine substitution" in furniture companies, some coating companies have continued to invest heavily in the research and development of water-based paint technology to compete for the huge market cake of water-based paint.


    "Three Great Mountains" block the development of water-based coatings


    Although people in the industry have predicted that water-based paint will usher in explosive growth last year.
    In fact, in the past year, although the use rate of water-based paint in the furniture industry has increased significantly, it has not reached the expected height, mainly because furniture companies also have their own concerns when using water-based paint.
    A few days ago, at a seminar on the development of water-based electrostatic spraying technology for furniture, He Fajian, president of the Beijing Furniture Association, said that electrostatic spraying is widely used, but the application of water-based wood paint in the furniture industry is still not much.
    There are many reasons, one It is that the national standards are not as high as those in Europe and America, so some fake water-based paints have an opportunity to take advantage of, and they will cause harm to the product quality of furniture companies that are using water-based paint.


    Second, furniture manufacturers worry that the performance indicators of water-based paint are not as good as paint.
    Nowadays, wooden furniture has higher and higher technical requirements.
    How to increase the fullness, saturation and hardness of water-based paint.
    .
    .
    No bottom.
    "In fact, many paint manufacturers and research institutes are currently spending a lot of time studying how to improve the performance of water-based paints.
    We can synthesize very high-performance resins in the school's laboratory, but that does not take the cost into consideration.
    Many Chinese people just need products that are cheap but not too poor in performance.
    ” said Qu Jinqing, a professor at the School of Chemistry and Chemical Engineering of South China University of Technology.
    Therefore, some of the products that have been developed have not been put into production.
    “In fact, the hardness of the coating is not higher.
    The better, everyone has a different feeling about hardness, and sometimes hard things tend to be less durable.
    "


    The third is the price problem.
    The current price of water-based paints is generally higher than that of oil-based paints.
    Many companies have led to low utilization rates of water-based paints in order to control costs.
