SHR -300L Stainless Steel Plastic Blender Mixing Machine For Chemical Industry
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.
Gelation hot mixing of the PVC blendstock is also the process of gelling the PVC blendstock. Unmixed PVC resin has different particle sizes and small particles at normal temperature, and it is easy to cause plasticization unevenness during extrusion molding. In the hot mixing process, the PVC resin is gradually melted, plasticized, and recrystallized to form a network morphology structure. From normal temperature to below 50 °C, after the PVC agglomerated powder and larger particles are rubbed and impacted, although the apparent density does not change much, the large stacked particles are sheared and broken into small particles, and After absorption of thermal energy and mechanical energy, the activity increases, and gradually combines with other particles, and the particle size increases. When the material temperature is below 90 °C, the temperature increase rate of the mixer is faster, then the temperature rises slowly, and the diffusion, shearing and convection effects are more severe. When the material temperature reaches 115 ° C, the small particles of PVC resin become large and uniform, the small particles gradually disappear, and the edge of the particles becomes transparent due to partial gelation. Under certain conditions, the degree of gelation of the PVC resin particles is Determined by the discharge temperature. When the feed temperature reaches 120 ° C, the PVC particles tend to be stable and the degree of gelation is increased. The particles in the whole hot mixing process are repeatedly combined and homogenized, the particle size is increased, and the densification is achieved, so that the apparent density of the PVC particles reaches a maximum value, which is beneficial to increase the extrusion yield, promote the uniform plasticization of the material, and improve the PVC profile. Welding strength, impact properties and other properties. The PVC dry mixed powder with good uniformity and good dry flow can be observed that the PVC resin has the characteristics of grain refinement and uniform particle size change, and exhibits high apparent density and partial gelation. The temperature of the hot mixed material and the temperature of the hot mixed material determine the process of uniform plasticization of the PVC material. The hot mixing temperature is too low, the PVC material is not plasticized unevenly, which affects the performance of the PVC profile; the hot mixing temperature is too high, the PVC material is prone to degradation in the mixing tank, and even the “paste” affects the production, so in general, the large Some PVC profile manufacturers use 120 °C as the rated temperature index for hot mixing. When the amount of calcium carbonate is large, the temperature of the hot mixed material can be appropriately increased to facilitate the balanced adsorption of calcium carbonate and the apparent density of the PVC material and the low melting point component. In addition to the hot mixing time, the hot mixing time needs to be controlled. It is also necessary to pay close attention to the hot mixing time in order to monitor the discharge temperature control. When continuous mixing, if the hot mixing reaches the discharge time is short (such as less than 7min, the interval between batches should be extended; when the mixer is used for a long time, if the temperature rises too slowly (such as less than 12min still can not reach Discharge temperature), can be unloaded in time, carefully check whether the thermocouple or thermometer indicates failure, and handle it. When the mixer blade is found to be seriously worn, it should be replaced in time to prevent the quality of the mixture from being affected. When the mixing time exceeds 2 times the normal mixing time or the wear of the blade ends is greater than 15 mm, the blade should be replaced.
