water duct Glass Fiber Reinforced Plastic Sand Pipe Dewatering Pipe assembly method

There are three main types of glass tube production process: reciprocating fiber winding process, continuous fiber winding process and centrifugal pouring process.

Reciprocating filament winding process (n) : in this process, the leaching glue tank with rotating mandrel for reciprocating motion, the long fiber glass with a certain Angle relative to the mandrel axial auxiliary, auxiliary Angle (that is, the winding Angle) baptism glue tank movement speed and the ratio of the core mold speed control, soak glue tank translational motion by computerized machine electric control.The number of winding layers gradually increases until the designed wall thickness is reached.After winding, the resin in the product is basically cured.After curing, the core die is removed from the glass tube.

Continuous fiber winding process (continuous method) : the pipe is in motion through a feed station for a resin prepreg roving, chopped fiberglass fiber and resin sand mixture, and the pipe is made in the continuous advance of the mandrel.

Centrifugal pouring process (n) : in this process, using glass fiber reinforced materials and sand, feeding on the bearing steel in the mould, injection plus unsaturated resin catalyst in die end, make its dipping reinforced material, under the effect of centrifugal force, the resin exchange fiber and filler in the air, so as to create a nonporous compact composite material, the effect of tube wall due to centrifugal force to form a smooth, bright and clean surface layer of rich resin, steel tubes under high temperature curing.The pipe made by this method is also called glass reinforced plastic sand pipe.

In the world, more and more manufacturers adopt the reciprocating fiber winding process than the other two production processes. One of the reasons is that the glass tube made by the reciprocating fiber winding process has a wider range of USES and better applicability.
