Production process exposure of FRP grille manufacturers
Ta Tou 2018-12-14 14:53
There are three main types of production processes for FRP grid manufacturers: reciprocating fiber wrapping process, continuous fiber wrapping process, and centrifugal casting process.
FRP grid manufacturers reciprocating fiber wrapping process (attributable to the fixed-length method): In this process, the dipping tank reciprocates with the rotating core mold, and the long-fiber glass filaments are placed relative to the core mold axis at a certain oblique angle. The auxiliary angle (that is, the surround angle) is controlled by the ratio of the moving speed of the dipping tank and 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 surrounding layers increases gradually until the wall thickness of the design is reached. After the wrapping is completed, the resin in the article is substantially cured. After curing, the mandrel was removed from the glass steel pipe.
FRP grating manufacturer's continuous fiber wrapping process (attributed to the continuous method): This process is a tube in motion through a feeding station for resin pre-impregnated roving, chopped fiberglass and resin sand mixture, the tube is in the core Made in a continuous process.
FRP grid manufacturer 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 to the bearing, and one end of the steel mold with catalyst is injected. Saturate the resin to impregnate the material. Under the effect of centrifugal force, the resin replaces the fibers and the air in the guess, so as to produce a fine composite material without pores. Because of the effect of centrifugal force, the inner wall of the tube forms a smooth, bright resin-rich Internal surface layer, the tube is cured at higher temperature. The pipe made in this way is also called FRP sandwich pipe.
