FRP injection molding technology Introduction

Injection molding technology is to improve the hand lay-up, semi-mechanized. Injection molding technology as a means of mechanical manual process, despite not represent the mainstream of advanced FRP molding process in the world, but in the history of the development of China's fiberglass is also an important process.

"Spray lining process" can be understood as airbrushed art glass steel winding container liner molding process. "Lining" is the FRP winding container liner, from the structure is divided into an inner liner and transition, to play the role of the main anti-corrosion seepage. FRP corrosion impermeable container structure consists of an inner liner, reinforced structural layer, the appearance of anti-aging layer. Make sure both good resistance to media corrosion, but also has enough physical and mechanical properties to meet the dress requirements. Glass fiber high tension, multi-level, multi-angle, encapsulated head wound, meet organic and inorganic solvents and chemically, electrochemically corrosive media storage, transit and production needs, to meet the non-electrolytic fluid transit, transport, elimination of static electricity the need to meet a variety of supporting anti-shear and mechanical load requirements and buried. Design flexibility, excellent structural performance of the container wall fiberglass chopped strand mat.

Filament-wound fiberglass resin system by changing or reinforcing material to adjust the tanks, towers and other physical and chemical properties, in order to meet the needs of different media and working conditions. Through structural layer thickness, winding angle and wall thickness structure is designed to adjust the carrying capacity of the tank, to adapt to different pressure levels, volume size, as well as tanks, towers of glass and steel requires some special properties, is isotropic metal materials can not be compared with. Corrosion-resistant, anti-leakage, good weather resistance. FRP has special corrosion resistance, corrosion during storage media, FRP materials exhibit other incomparable superiority, can withstand a variety of acids, alkalis, salts and organic solvents, it can see the application of FRP is very common, but FRP product quality is dependent on several factors of raw materials, construction technology. FRP spray lining process of emerging as a domestic semi-mechanized production process is a great advantage exists.
