Plastic is a rubber processing process, the application of mechanical or chemical methods, so that the relative molecular weight of raw rubber, viscosity reduction, increase plasticity, easy to follow the mixed molding process. In the open mixer, the plastic is plastic by cutting the rubber molecular chain by low temperature mechanical force, and has the advantages of good plastic quality and shrinkage. So specifically, how is the open mill used?
Let's take a look! How is the open mill used?
1, open the mill first adjust the roll distance, maintain the balance of roll distance. If the size of the roller distance adjustment at both ends is inconsistent, resulting in partial roller load, it is very easy to damage the equipment, which is strictly prohibited. From the feed habit are from the dynamic input side to join, in fact, this is not reasonable. According to the bending moment diagram and torsion diagram, the feed should be at the end of the speed ratio gear.
2, because the synthetic bending moment and torque of the transmission end of the smelting machine are greater than the speed ratio gear end, do not first add a hard rubber strip in the middle of the drum, where the synthetic bending moment is larger, up to 2820 tons. The feed material should be gradually increased, the weight of the feed block should not exceed the provisions of the equipment instruction manual, and the feed sequence should be fed from small to large.
3, in the use of the smelting machine, should be first scratched (cut) knife, and then the hand to take glue. If it is not scratched (cut), do not pull hard. Do not use one hand to push into the drum. If the glue beats under the roller and is not easy to roll, do not press the glue by hand. When pressing, it must be held with fists and cannot exceed the horizontal direction of the top of the drum.
4. When measuring the temperature of the roll with the mold of the smelting machine, the back of the hand should be opposite to the rotation direction of the drum. The cutter must be placed in a safe place, and when cutting the glue, the lower part of the roller must be cut off, and the blade must not face toward its own body.
