SHR-500L Fast speed plastic PVC and EVA mixer blender for soft shoes mixing
High-speed mixer is mainly used for mixing, stirring, drying, coloring, primary plasticization and other materials of plastics, building materials, chemical pigments, rubber and other industries.
Since the material is moving at a high speed, the friction between the material and the slurry is very high, which causes the temperature of the material to rise rapidly. Not only the heating amount of the wall of the pot is reduced correspondingly, but also the absorption effect of the resin on the speed increasing agent is facilitated. The agitating pulp is made of stainless steel and carefully machined to wear and corrosion. The cold mixing part is composed of a pot cover, a pot body, a transmission, a base discharge, and an electric control. The lid can be rotated in a horizontal direction and provided with a safety protection device. When the lid is not tightly closed, the switch unit is turned on, and the motor is turned on. If it is not started, when the lid is not covered, the stirring slurry will cause a personal accident, and the cover is provided with a feeding hole, which can be put into the hot mixed material. The pot body is made of stainless steel, and the inner wall is extremely smooth and hard, and has the characteristics of wear resistance, corrosion resistance and non-sticking. The wall of the pot is provided with a cooling jacket to achieve a cooling effect through a water cooling cycle. The transmission part is driven by the starter motor through the V-belt wheel to input the power to the main shaft, so that the stirring slurry rotates, so that the hot mixed material cooling mixing base is welded by steel plate and angle steel, and the adjusting bolt is provided to adjust the transmission triangle belt. It is elastic and the bottom part is fixed with the anchor screw. The discharge part is cast from an aluminum alloy. It is equipped with a starting discharge door. The cylinder and the material door are directly connected by one line, the pressure is reliable, the sealing is good, the opening and closing is flexible, and one air compressor of 0.39-0.49Mpa is used (selected by the user), and the unloading mode can be automatically controlled by the material temperature in the pot. And use the button to manually control the opening and closing of the discharge door..
The hot mixing sequence has certain influence on the mixing quality and the mixing tank wear. PVC resin and heat stabilizer are added at low speed; impact modifier, processing aid and internal lubricant are added at high speed and 60 °C; high speed and Adding filler, titanium dioxide, ultramarine blue, external lubricant, UV-531, color masterbatch antioxidant, etc. at 80 °C. Function: Firstly add heat stabilizer to fully exert its thermal stability to PVC resin; early addition of internal lubricant is beneficial to the initial gelation of PVC material; premature addition of titanium dioxide will affect the surface finish and color of the product, and The mixing tank is worn out too early. Adding calcium carbonate not only wears out the mixing tank, but also preferentially absorbs the internal lubricant. Premature addition of processing aid will preferentially absorb the lead salt stabilizer, so that the PVC absorbs the lead salt stabilizer. The amount is reduced, which leads to the decrease of material stability; premature addition of external lubricant will reduce the frictional heat and shear heat of the mixture, affecting the mixing effect and the dispersion performance of the stabilizer; premature addition of the color masterbatch will affect the color of the PVC profile. The total amount of hot mix is also not negligible. Generally, each batch of material should be controlled to about 75% of the volume of the hot mixing tank to avoid excessively long (or too short) mixing time, resulting in over-plasticization (or uneven plasticization) of the material. Cold mixing technology principle The working principle of cold mixing and hot mixing is different. Hot mixing generally does not have external heating equipment. It mainly relies on the high-speed rotation of the blade material to collide with the material and the friction energy generated by the friction and shear of the material and the cylinder, so that the normal temperature material becomes a hot mix. The barrel of the cold mixing machine has a sandwich, and cooling water flows in the interlayer; and the volume of the general cold mixing machine is about 3 times that of the hot mixing machine. The hot mix entering the cold mixer is in a relatively spacious environment and the rotating blades are continuously stirred and tumbling, and the heat is absorbed by the cooling water in the interlayer of the inner wall of the cylinder, and gradually cools itself. PVC materials should be cold mixed immediately after hot mixing to prevent the hot mix from being stored at high temperatures for a long time to degrade. At the same time, if the hot mix is not subjected to cold mixing, it is easy to re-absorb the water in the natural state, which has an adverse effect on the extrusion. Cold mixing can not only prevent the water-absorbing and moisture-reducing phenomenon of PVC materials cooling at high temperatures, but also the process of further discharging the intermolecular moisture of PVC materials during the exothermic process. The cold mixed discharge temperature of the PVC material plays an important role in ensuring the quality of the dry mix.
