Performance and advantages: In order to adapt to the market demand, the cone double main engine series FRPP/PVC double wall bellows production line independently developed by Kingweft Company has the following characteristics:
1. The overall energy consumption of the production line is low, the transmission efficiency of the cone double main engine is higher than that of the single screw main engine, and the installed power is lower than that of the single screw main engine.
2. The extruder directly eats the powder, and uses the formula of raw material + calcium powder to reduce the cost of raw material and improve the ring stiffness of the pipe;
3. The extruder has a vacuuming device, which overcomes the problem of bubbles in the inner and outer walls of the pipe caused by water in the raw material.
4. Add a 30/28 co-extruder with a special coating die to coat the outer layer of bellows to make the surface of products brighter and stronger. The surface coating accounts for about 2-4% of the total weight of the product.
