Will FRP vessels release harmful substances during use?

FRP vessels are widely used in various industries. They are made of glass fiber reinforced plastic, which has become a common choice in many industries due to its good corrosion resistance, strength and lightweight properties. However, with the increasing requirements for environmental protection and safety, more and more people are beginning to pay attention to whether FRP vessels will release harmful substances during use.
The main components of FRP vessels are glass fiber and resin. Glass fiber itself does not contain harmful substances, but the type and quality of resin directly affect the safety of the vessel. Common FRP vessels use materials such as epoxy resin, unsaturated polyester resin or acrylic resin. These resins need to undergo a curing reaction during the production process so that the final molded vessel has stable physical properties. However, in some special cases, some components in the resin may be released, especially when the vessel is subjected to extreme environments such as high temperature, strong acid, and strong alkali.
During the long-term use of FRP vessels, especially when exposed to high temperature or strong ultraviolet radiation, the resin surface may undergo aging reactions. Some organic compounds in the resin, especially those that are not fully cured, may gradually decompose at high temperatures or long-term exposure to sunlight, releasing trace amounts of volatile organic compounds. These substances may have a certain impact on air quality and even pose a potential risk to human health.
Although the corrosion resistance of FRP vessels is excellent, when they come into contact with certain chemicals such as strong acids, strong alkalis or organic solvents, the structure of the vessel may degrade, and some chemical components in the resin may be dissolved or released into the liquid in the vessel. This will not only affect the purity of the stored substances, but may even trigger chemical reactions and lead to the production of harmful substances.
Although the risk of FRP vessels releasing harmful substances is low under normal use, in some cases, especially when the vessel is physically damaged or used improperly, cracks or scratches may appear on the inner wall of the vessel, which will affect its sealing performance. If toxic and harmful chemicals are stored in the vessel, the possibility of leakage will increase, causing pollution to the surrounding environment.
Many FRP vessel manufacturers adopt strict quality control standards during the production process to ensure that the resin materials used meet relevant environmental protection and safety standards. High-quality FRP vessels usually undergo a rigorous curing process, which removes most of the harmful substances and reduces the problem of harmful substance release that may occur during use. In addition, with the continuous advancement of science and technology, many new environmentally friendly resin materials have begun to be used in the production of FRP vessels. These materials are resistant to high temperatures and chemical corrosion, and also have low volatility, further reducing the potential threat to the environment and human health.
