There are three main types of glass steel grating production process: reciprocating fiber winding technology, continuous filament 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 winding layer increases gradually and reaches the wall thickness of the design. After winding, the resin in the product is basically solidified. After curing, the core mold is removed from the glass tube.
Continuous filament winding process (continuous process) : the process is in motion through a supply pipe resin presoak roving, chopped glass fiber and resin sand mixture feeding station, pipe is in the core mold made of continuous progress.
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 tubes made in this way are also called glass reinforced plastic sand tubes.
World using reciprocating system of filament winding process tube manufacturers more than the other two production technology manufacturers, one of the reasons is made in reciprocating filament winding process of glass steel pipe has a wider range of USES, the applicability is better.
