Unlike the metal frame screen, plastic composite screens don’t need to use adhesives to glue the wire cloth to the panel, just use the heat and melt technology, the wire cloth will be sealed into the screen frame to form a firm bond.
This new design improves solids-control performance by increasing screen life and fluids-handling capacity while providing a screen that is lighter in weight than older, metal-backed designs.
In order to suit a wide range of drilling conditions, Composite Screens are available with Ultra Fine Mesh, a triple layer square opening cloth, High Conductance Mesh, a triple-layer rectangular opening cloth with excellent fluid-handling capacity.
The main feature of composite frame screen is as follow:
1. High strength plastic frame and moderate tension screen cloth that form a reliable whole, so it greatly enhance the tolerable flow.
2. The screen is divided into several independent small cloths to pervent excessive expansion of local damage. At the same time, with a special rubber plug to repair the damage,it can save the use time and reduce the use cost.
3. Rapid wedge tensioning devices make the installation of the composite frame screen more convenient, and save the time of changing the screen by stop the machine.
4. Excellent polyurethane material of the frame enhance the corrosion resistance of the composite frame screen greatly. It have a good stock absorption and extend the working life of the composite frame screen.
