معجون الألمنيوم القائم على الماء refers to a suspension containing fine aluminum flakes or aluminum powder with water as solvent. Compared with traditional solvent aluminum paste and oily aluminum paste, water-based aluminum paste has the advantages of being green, non-toxic, non-flammable, safe and reliable, and is widely used in many fields such as automobile manufacturing, construction engineering, home furnishing manufacturing, electronic products, and industrial manufacturing.
There are a wide variety of water-based aluminum pastes. According to different effects, water-based aluminum paste can be divided into fine white silver paste, flash silver paste, and imitation electroplating silver paste; according to different particle sizes, it can be divided into 20μm water-based aluminum paste, 40μm water-based aluminum paste, and 60μm water-based aluminum paste; according to different floatation, it can be divided into floating water-based aluminum paste and non-floating water-based aluminum paste; according to different preparation processes, it can be divided into secondary coating aluminum paste and passivation aluminum paste. Different types of water-based aluminum pastes have different performance and uses. In the future, with the growth of demand for subdivided product applications, the development trend of the water-based aluminum paste industry will continue to improve.
Water-based aluminum paste is usually made by coating process. It uses atomized aluminum powder, surface treatment agent and other raw materials. First, a dense adsorption film is adsorbed on the surface of the atomized aluminum powder, and then organic silicon dioxide and other silicon-containing compounds are coated on the surface of the adsorption film to finally obtain the finished product. After years of development, the technical level of water-based aluminum paste in my country has been continuously improved, but there is still a certain gap compared with developed countries overseas.
Water-based aluminum paste can be used as coating and ink, and has broad application prospects in many fields. In the field of automobile manufacturing, water-based aluminum paste can be used in the painting of automobile parts and automobile bodies; in the field of construction engineering, it can be used as anti-corrosion coating for building exterior walls and roofs. In recent years, driven by national policies, my country's coating industry has gradually developed in the direction of environmental protection. Water-based aluminum paste uses water as a dispersion medium, which reduces the use of chemical solvents and has extremely low emissions of volatile organic compounds (VOCs). In the future, as the market share of environmentally friendly coatings increases, the development speed of the water-based aluminum paste industry will further accelerate.
According to industry analysts, as an environmentally friendly coating, water-based aluminum pigment has broad application prospects in many fields. In the future, with the rapid development of downstream industries, its market space will further expand. Compared with developed countries overseas, my country's water-based aluminum paste industry started late, and high-end demand is highly dependent on imports. In the future, with the continuous efforts of local enterprises and technological progress, my country's high-performance water-based aluminum paste market share will increase.
