    Water-based industrial paint is mainly water to do diluents, do not need curing agents, dilute some solvents, is different from oil-based industrial paint a new type of environmental protection anti-rust anti-corrosion coating. The application range of water-based industrial paint is very common, bridges, steel structures, ships, mechanical and electrical, steel and so on can be seen everywhere. Because of its energy-saving, environmental protection, will not cause harm and pollution to the human body and the environment, so popular with users, is the future direction of the paint industry, but also an alternative to oily paint products . So, what are the common water-like industrial paint problems?
    01
    what is water-powered industrial paint?
    if a definition is given to the water-based industry, there are two aspects:
    water-based: water as a thinner, no other solvents added to the process of use. The external manifestation is small odor, non-combustible and non-explosive.
    paint: coatings that use specific construction methods to achieve consistent appearance and performance. There are clear or experimental requirements for corrosion protection and mechanical properties.
    02
    characteristics of water-based industrial paint:
    1) adapt to the factory coating.
    e.g. water-based paint for the inner wall of the radiator, which can be baked in the oven together with the powder coating on the outer wall of the radiator, and the drying of the inner and outer coatings can be done in one process.
    water-specific paint for automotive parts to meet the immersion process in complex shapes.
    2) has a clear anti-corrosion needs:
    mainly includes salt spray resistance, oil resistance, water resistance, hot water resistance and other performance indicators.
    , such as water-resistant automotive parts coating, requires salt mist resistance ≥300h, for water tanks and other corrosive components, salt spray resistance ≥500h.
    3) has a mature coating system:
    from the substrate treatment, primer, intermediate paint, paint selection and matching, coating thickness, etc. , in the coating design has clear requirements.
    is
    03 water-powered industrial paint really non-toxic?
    , water-based industrial paint is mainly water to do diluents, do not need curing agents, dilute materials some solvents, is different from oil-based industrial paint, a new type of environmental protection anti-rust anti-corrosion paint. Water-based industrial paint applications are very wide, bridges, steel structures, ships, mechanical and electrical, steel and so on can be seen everywhere. Because of its energy-saving, environmental protection, will not cause harm and pollution to the human body and the environment, so popular with users, is the future direction of the paint industry, but also an alternative to oily paint products.
    the
    trend of water-powered industrial paint development in 2004?
    Water-based industrial paint is a water-based dissolved medium of paint, like solvent-based paint, water-based industrial paint with non-toxic environmental protection, odor-free, volatile very few, non-combustible and other advantages, is a non-organic solvent as a thinner green products. Water-based industrial paint in China started late, with the increasingly perfect national environmental regulations, coating enterprises and the public awareness of environmental protection, the development of water-based and other environmental protection coatings has become imperative. Traditional architectural coatings, automotive electrophoresis primer water-based has been popularized, the current water-based industrial paint technology is becoming more and more mature, began to gradually to cars, containers, construction machinery and other fields to promote the application.
    is
    performance of water-powered industrial paint in 05?
    1) Environmental protection: water-based paint is water as a solvent, in the process of use will not cause harm to the human body, will not pollute the environment, load people's green life concept. And the use of water as a solvent greatly saves resources.
    2) adaptable, can be sprayed directly in any environment, and adhesion is superior.
    3) Water-like paint coating tools are easy to clean and do not require a large amount of detergent.
    4) paint film density is high, easy to repair.
    5) has good supporting properties, can be matched with all solvent-based coatings and covered.
    6) good filling, not easy to burn, paint adhesion is high.
    the
    disadvantages of water-powered industrial paint in 2006?
    1) During the construction process, the surface requirements of the sprayed material are particularly high, if the surface cleaning is not clean, it will lead to the coating film to produce shrink holes.
    2) will corrode the coating equipment, so the substrate must be made of stainless steel, but stainless steel is more cost-effective.
    3) The thermal stability and water resistance of water-resistant industrial paint are relatively poor, which will affect the performance of the coating film in the process of use.
    4) If a high boiling point additive is added to the water-related industrial paint, it will produce fumes when baked, affecting the appearance of the coating surface.
    5) The evaporation potential heat of water-like paint is large, and the drying time of paint film is slow.
    6) is more expensive than solvent-based coatings.
    07
    water-powered industrial paint on the construction environment what requirements?
    1) Strictly prohibit contact with oily substances, stirring well before use, according to actual needs, appropriate water dilution, but generally add 0-10% of the water is the best.
    2) brushing, roller coating, spraying, immersion coating are available, the construction temperature ≥5 degrees C
    3) before construction should be removed surface oil, sand debris, loose rust, rust layer thickness of not more than 120 microns.
    4) storage temperature ≥0 degrees C, placed in a cool and dry place storage, anti-freeze, anti-riot sun, shelf life of 18 months.
