SHR -300L Stainless Steel Plastic Blender Mixing Machine For
Chemical Industry
Application:
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.
Features:
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.
