Introduction to FRP injection molding technology
Writer:admin    Released:2018-08-31 17:15:44    Type:【L】【M】【S
Spray molding technology is the improvement of hand paste molding, semi - mechanization degree.Injection molding technology, as a manual process with the help of machinery, is not representative of the world's advanced GFRP molding process mainstream, but in the development of China's GFRP is also an important process. "Spray lining process" can be understood as the process of forming the inner lining of GFRP wrapped container with spray gun technology."Lining" is the lining of FRP wrapped container, which is divided into lining layer and transition layer on the structure, mainly playing the role of anti-corrosion and anti-seepage.The GFRP container structure is composed of anti-corrosion and anti-seepage lining, reinforced structure layer and exterior anti-aging layer.Ensure that there is good dielectric resistance and adequate physical and mechanical properties to meet the dressage requirements.Using glass fiber high tension, multi-level and multi-angle, the head coil, inorganic, organic solvent and has a chemical and electrochemical corrosion media storage, transfer and production needs, meet the electrolyte fluid transfer, transmission, eliminating the need of electrostatic, meet all kinds of bearing shear resistance and buried with the load on the mechanical requirements.Great flexibility in design and excellent performance of container wall structure.Fiber winding GFRP can adjust the physical and chemical properties of storage tanks, towers, etc. by changing the resin system or reinforcing materials to meet the needs of different media and working conditions.The bearing capacity of the tank can be adjusted through the design of the structure layer thickness, winding Angle and wall thickness, and it can not be compared with the metal materials of isotropy to adapt to the requirements of different pressure classes, volume sizes, and some special properties of FRP storage tanks and towers.Good resistance to corrosion, leakage and weather.The corrosion resistance of glass fiber reinforced plastic has special, in the storage of corrosive medium, glass fiber reinforced plastic shows incomparable superiority by other materials, can be resistant to many kinds of acid, alkali, salt and organic solvent, thus the application of FRP is very common, but the quality of the glass fiber reinforced plastic products is depend on the raw materials, construction technology and so on several factors.As a new semi-mechanized production process in China, GFRP spray lining has great advantages.
