With the pressure of environmental protection policies, people’s awareness of environmental protection has been continuously improved; In particular, provinces and cities across the country have issued VOC emission limit standards; Replacing paint with water-based paint can effectively reduce the VOC content in the atmosphere, thereby improving haze weather, water-based paint, etc. The development of environmentally friendly paints has brought opportunities. Industrial paints account for 70% of the paint consumption each year. Therefore, the promotion of water-based paints is also the mainstream direction of the paint industry.
Introduction of water-based industrial paint:
Water-based industrial paint is mainly made of water as a diluent, which is a new type of environmentally friendly anti-rust and anti-corrosion paint that is different from oil-based industrial paint. The application range of water-based industrial paint is extremely wide, and it can be seen everywhere in bridges, steel structures, ships, electromechanical, steel, etc. Because of its energy saving and environmental protection, it will not cause harm and pollution to the human body and the environment, and is very popular among users.
Classification of water-based industrial paints:
The common varieties in the water-based industrial paint market include acrylic anti-rust paint, alkyd anti-rust paint, epoxy anti-rust paint, amino baking paint, etc., covering steel structures, containers, automobiles, mechanical parts, templates Climbing frames, pipelines, highway bridges, trailers and other fields; From the construction process, there are dip coating, spraying (including electrostatic spraying), brushing, etc.
The performance of water-based industrial paint:
(1) Environmental protection: low odor and low pollution, no toxic and harmful substances are produced before and after construction, which truly achieves green environmental protection.
(2) Safety: non-flammable and non-explosive, easy to transport.
(3) Coating tools can be cleaned with tap water, which greatly reduces the consumption of cleaning solvents and effectively reduces the damage to construction personnel.
(4) It is easy to dry and has strong coating adhesion, which improves work efficiency and reduces labor costs.
(5) Wide range of applications: automobiles, ships, grids, machinery manufacturing, containers, railways, bridges, wind power blades, steel structures and other industries.
The function of primer and topcoat:
After the primer is applied, the nano-scale primer resin will quickly penetrate into a certain depth along the micropores of the substrate. After drying, the resin will seal the substrate, which is especially critical for rust prevention; the middle coating mainly plays the role of transition and increasing the thickness of the paint film. Function; topcoat is mainly used to achieve the final coating effect, including gloss, feel, protection, etc., and finally forms the final coating structure together with the original coating.
Construction Notes:
(1) It is strictly forbidden to contact with oily substances. Stir well before use. It can be appropriately diluted with tap water according to actual needs, but generally adding 0-10% water is the best.
(2) Brush coating, roller coating, spray coating and dip coating are all acceptable, and the minimum construction temperature can be ≥0℃.
(3) Before construction, the surface oil, sand debris and loose floating rust should be removed.
(4) Storage temperature ≥0℃, store in a cool and dry place, prevent freezing and sun exposure.
(5) In bad weather such as rain and snow, construction cannot be carried out outdoors. If construction has been carried out, the paint film can be protected by covering it with a tarpaulin.
