Runfeng FRP roofing sheet production process
1. Inject the resin and various additives into the mixing tank in proportion to each other through a precise metering pump;
2. After the mixed resin is fully stirred by the stirring tank, it will flow on the flat lower film of the dipping platform;
3. As the lower film moves forward under the traction, the mixed resin passes through the scraper with limited thickness and width on the lower film to obtain the required thickness and width of the mixed resin;
4. At this time, the fiber felt is naturally bonded to the resin through the felt guide shaft, or the chopped fiber is dispersed by the spinning roller and falls on the resin surface evenly and naturally;
5. After the resin is combined with the chopped strand mat or chopped fiber, it will continue to move under the action of traction. After the fiber is fully combined with the resin through the dipping preheating platform, the lower layer of air bubbles will be discharged.
6. The fully combined mixed resin and fiber continue to pass through the extrusion shaft under the action of the lower film traction. When passing through the squeezing shaft, the upper film drops and combines with the fiber resin tape on the lower film to form a fiber resin interlayer belt with upper and lower film protection. At the same time, air bubbles are discharged through the squeezing shaft to limit the thickness of the Runfeng FRP roofing sheet;
7. The fiber resin sandwich belt protected by the upper and lower films continues to run under the action of traction and reaches the bubble detection platform. After manual inspection, the air bubbles remaining in the fiber resin tape will be discharged and then enter the heating box.
8. The fiber resin interlayer belt enters the first zone of the heating box for 8-9 meters (50-70 degrees Celsius), prefabricated by a mold;
9. Then enter the second zone of the thermostat box for 8-12 meters (75-90 degrees Celsius), and then the fiber resin interlayer belt is formed by a mold and gel;
10, and then enter the three areas of the incubator, the formed semi-cured board can be completely cured.
11. At this time, the board continues to move and reaches the motion source tractor of the equipment, and at the same time passes through the length-measurement counter.
12. After passing the tractor, reach the trimming system, and trim the edge of the plate as needed;
13. Finally, it reaches the fixed-length cutting system and automatically cuts the length as required;
14. Cut the finished Runfeng FRP roofing sheet according to the preset length.
