Name: PVC Granulating Machine, PVC Granulator, PVC Plastic Granulating Machine, PVC Plastic Granulator, Plastic Granulator.
Formula of PVC cable material
70H-PVC cable material formulations, such as PVC type three 75PHR-- active calcium carbonate 35PHR---DOP (Plasticizer) epoxy 25PHR--- soybean oil soybean oil 3PHR, chlorinated paraffin 20PHR-- stabilizer 2.8PHR-- hard acid 0.6PHR - CPE 9PHR - litmus 1PHR
(1) preparation: stabilizer, filler, pigment with 80 mesh sieve, and were added plasticizer soaked with three roller grinding machine or colloid mill for grinding. Spare after weighing. Increasing plastic agent are mixed evenly preheat 90 DEG C stand-by; (2) high mixing machine: Investment PVC resin, then adding plasticizing agent stirring for a while, until the resin will plasticizing agent absorption after the addition of stabilizer, by friction heat the material temperature rose to about 90 DEG C, adding filler, colorant, material temperature rose to 110 DEG C, the material is discharged to cooling mixing machine cooling, to 45 to 50 DEG C material. Table set different temperature of different materials according to the degree of stable set different temperature of different material (3) PVC granulation machine stable set: 1. Order double screw temperature setting: 140----160 according to 2. Under the order of single screw set: 125----145; temperature control set, the actual temperature reaches the set temperature heat preservation after 40 minutes, to start production; this is to ensure that the equipment in the former one day leave the material, so the former days leave the material softening; this does not hurt the device (4): 1. The high mixing machine of PVC materials into the spiral feeder hopper, the spiral feeder to the powdery material input - order parallel twin-screw extruder
2, the upper order parallel double screw extruder to mix the material evenly, the temperature of 140-160 degrees Celsius in the state to complete the mixing and mixing, fully dispersed evenly. The final extrusion of the mixed material into the melt (temperature at 130-140 degrees C), directly into the large diameter lower order single screw extruder.
3 lower order single screw extruder to melt the 120 degrees Celsius, in a low speed, high pressure and cooling conditions to complete the extrusion granulation. Extrusion temperature has been reduced to 120-140. At this time to complete the air-cooled die surface eager to grain, and not the clay in the pelletizing process.
4. Air-cooled die surface eager to cut the particle, after cooling of the secondary air cooled cyclone separator, particle temperature dropped to 35 to 40 DEG C, after air cooling extended vibration sieve, particle temperature dropped to room temperature to into the finished product bin packing
Matters needing attention:
1, the main motor and oil pump motor has electrical chain, that is, the pump motor does not start, the main motor can not be started; the main motor does not stop, the pump motor can not be stopped. 2, the main motor and the feeding motor with electrical chain, that is the main motor does not start, the feeding motor can't start; do not stop feeding motor main motor, main motor can not stop. 3, the main motor control cabinet with over current protection, in addition, also has a mechanical protection device, generally for nylon shear pin type safety coupling. When the design torque is exceeded, the shear pin is cut off and the drive box stops working. 4, when the head pressure exceeds the set alarm value, the material pressure alarm signal light and automatic shutdown. 5, the production of raw materials, is prohibited to bring any metal debris. 6, when the machine is running, it is strictly prohibited to use metal objects in the opening of the cylinder to clean up the material. 7, pressure sensor and material temperature thermocouple assembly. When there are materials in the nose, must be heated, the material to be softened before the installation and disassembly. 8, the tube cooling system of the circulating water, please use the softened water or distilled water. 9, screw only allows low speed (less than or equal to 20R / min) to start, idle time is not more than 2 minutes, feeding to be die hole discharging, in order to gradually raise the speed.
