How to make expensive FRP grills
There are three main types of FRP grid production processes: reciprocating fiber winding process, continuous fiber winding process, and centrifugal casting process. Reciprocating fiber winding process (belonging to the fixed length method): In this process method, the dipping tank reciprocates with the rotating core mold, and the long-fiber glass filaments are put relative to the core mold shaft at a certain oblique angle.
The angle (that is, the winding 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-electricity. The number of winding layers is gradually increased until the designed wall thickness is reached. After the winding is completed, the resin in the product is substantially cured. After curing, the mandrel was removed from the glass steel pipe.
Continuous fiber winding process (belonging to the continuous method): The process is that the tube passes through a feeding station that supplies resin prepreg non-twist roving, chopped fiberglass fiber and resin sand mixture, and the tube is continuously advanced in the core mold. Made in.
Centrifugal casting process (belonging to the fixed length method): In this process, cut glass fiber reinforced material 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 The impregnated reinforced material, under the action of centrifugal force, the resin replaces the air in the fiber and the filler, thereby producing a dense composite material without pores. The inner wall of the pipe forms a smooth and smooth resin-rich inner surface layer due to the action of centrifugal force. Cured at higher temperatures. The pipe manufactured by this method is also called glass fiber reinforced plastic sandwich pipe.
There are many more manufacturers in the world that use the reciprocating fiber winding process to produce pipes than the other two production processes. One of the reasons is that the glass steel pipe manufactured by the reciprocating fiber winding process has a wider range of applications and is more suitable.
