With the development of industry, the problem of environmental pollution has become one of the common concerns in the world today, and many countries have invested huge human and material resources to devote themselves to this new industrial sector of the environmental protection industry.
FRP has been widely used in water supply and drainage pipeline projects. In recent years, more and more wastewater and corrosive media are increasing in type and intensity of corrosion, which requires the use of materials with better corrosion resistance, and corrosion-resistant FRP is the best material to meet this demand.
Applications of composite materials in environmental protection include general industrial waste gas treatment, oil and water treatment, sewage treatment with toxic substances, waste incineration treatment and municipal wastewater deodorization treatment.
The excellent corrosion resistance of FRP means that this material has active, non-polluting properties, it is logical to become a highly clean item, such as storage of high-purity water, drugs, wine, milk and other optional materials. The United States and Japan have such products of professional factories, in the use of a wealth of experience.
The chloralkali industry is one of the earliest applications of FRP as corrosion-resistant material, and FRP has become the primary material for the chloralkali industry. Back in the early 1950s, FRP was first used to collect hot (93°C), wet chlorine gas and organic substances from ink electrodes. This application replaced the phenolic asbestos plastics of the time. Then FRP was used to replace concrete electrolyzer covers, solving the problem of corroded concrete froth falling into the electrolyzer. From then on, FRP was gradually used in various piping systems, gas blast motorization, heat exchanger shells, brine tanks to pumps, pools, flooring, wall panels, grilles, handles, railings and other building structural parts. At the same time, FRP also began entering various chemical industry fields.
The paper industry uses wood as raw material, and the process of making paper requires acid, salt, bleach, etc., which has a powerful corrosive effect on metal, only FRP material can resist such a harsh environment of antibacterial elements, FRP has shown its excellent corrosion resistance in the production of pulp in some countries.
Most of the acids used in metal surface treatment plants are hydrochloric acid, which is basically no problem with FRP.
