Shanghai Infiltration Equipment Company: Application of Infiltration Agent in Military Industry

The infiltration technique is to infiltrate the porous workpiece by the infiltration agent under pressure to achieve the purpose of filling the gap. The infiltration technology is a new technology developed by modern technology. Infiltration technology is widely used in the sealing of casting defects, wood insect proof, anti-corrosion, flame retardant, powder metallurgy parts reinforcement, corrosion and sealing, anti-alkali or acid corrosion of cement products, moisture and insulation of electrical and electronic components.

The application of modern industrial infiltration technology can be traced back to the casting plugging process in the 1930s, when the water filled glass was used to fill the casting voids. In the 1950s and 1960s, with the development of the automobile industry, the industrialized countries such as the United States, the former West Germany, and the former Soviet Union promoted the development of the first generation of infiltration agent-sodium silicate type infiltration agent for the sealing of pressure-bearing castings. And application, and developed from a partial or atmospheric pressure infiltration process to a vacuum pressure infiltration process.

Since the 1970s, the emergence of the energy crisis has promoted the development of automobiles. Many cast iron parts have been replaced by light metals such as aluminum, magnesium and zinc and their alloy materials to reduce the weight of automobiles, reduce energy consumption and improve the performance of automobiles. However, light metal castings are prone to micropores, resulting in leakage of pressurized castings. At the same time, the widespread use of powder metallurgy sintered parts further saves material and machining costs. The problem of leakage of porous materials has been urgently solved, which has promoted the demand for infiltration technology. At the same time, the development of the chemical industry has promoted the research and development of infiltration agents. A wide variety of applications and a wide range of infiltration agents with excellent performance have emerged. The second generation of polyester infiltrant and anaerobic and thermosetting properties have been introduced. Acrylate type third generation infiltration agent. The infiltration method and the infiltration process have been continuously improved, and the infiltration equipment has been developed to large-scale and semi-automatic, which has further promoted the wide application of infiltration technology. Some Shanghai infiltration equipment companies have said that the infiltration technology has been used by military industry in advanced industrial countries. And recognized by cutting-edge technology departments. The application of infiltration technology has promoted the thinning of many complex structural designs. At present, some foreign companies have used infiltration technology as a design method and an indispensable production process in the production of castings, and advocated infiltration of castings. The high infiltration efficiency and the significant economic effect of the infiltration treatment have led to the recognition of the value of this technology in industrial production.
