How much do you know about the requirements for the production of FRP gratings?
There are three main types of FRP grid production processes: reciprocating fiber wrapping process, continuous fiber wrapping process, and centrifugal casting process. Reciprocating fiber wrapping process (attributable to the fixed-length method): In this process, the dipping tank reciprocates with the rolling mandrel, and the long-fiber glass filaments are placed relative to the mandrel axis at a certain oblique angle.
The angle (that is, the surround angle) is controlled by the ratio of the moving speed of the dipping tank to the rotational speed of the core mold, and the translational movement of the dipping tank is controlled by a computerized machine. The number of surrounding layers is gradually added, and the planned wall thickness stops. After the wrapping is completed, the resin in the article is cured completely. After curing, the mandrel was removed from the glass steel pipe.
Continuous fiber wrapping process (attributable to the continuous method): The process is that the pipe passes through a feeding station that supplies resin pre-impregnated roving, chopped fiberglass fiber and resin sand mixture, and the pipe is continuously advanced in the core mold. Made in.
Centrifugal casting process (attributable to the fixed-length method): In this process, blocked glass fiber reinforced materials and sand are fed into a steel mold fixed on a bearing, and an unsaturated resin with a catalyst is injected at one end of the steel mold to make Its impregnation enhances the data. Under the effect of centrifugal force, the resin replaces the fibers and the air in the guess.
Then a fine composite material without pores is produced, because of the effect of centrifugal force, the inner wall of the tube forms a smooth, bright inner surface layer with resin, and the tube is cured at a higher temperature. The pipe made in this way is also called FRP sandwich pipe.
There are many more manufacturers in the world that use reciprocating fiber wrapping process tubes than the other two production process manufacturers. One of the reasons is that the glass fiber reinforced plastic pipes made by reciprocating fiber wrapping processes have a wider range of applicability.
