EFFECT OF TEMPERATURE ON THE WOOD PROCESSING PERFORMANCE IN SOUTH AFRICA

WPC in the extrusion process is mainly affected by the barrel temperature
And impact of the head temperature.Wood plastic composite wall cladding panel Barrel temperature of the composite material is mainly a mixture of
Refining plasticizing effect have a decisive impact. The temperature of the extrusion die
Forming an important influence.
With the barrel temperature, the melt viscosity of the composite system apparent
Decline. For extrusion materials, elevated temperatures help the flow
Increases, the first group experiment extrusion machine set higher temperatures, but
Temperatures cause burning wood fiber, resulting viscosity is too low and can not
Generate sufficient head pressure, high temperature of the extruder so that the material viscosity
Fall, is not conducive to cooling stereotypes, easy to make the product surface weld marks, so
Thus, to meet on the basis of the quality of plastics material,Wood Plastic Composite Outdoor Flooring should be lower
Die head to head transition temperature of the cooling and sizing of control
Quality of the products is very significant. If the temperature is too low this section
The viscosity increases WPC, flow difficulties, runner wall
Stream is cooled and solidified at the prematurely, so that the material can not be filled head
Runner, difficult extrusion; If this segment temperature,[url=http://www.woodplasticcompositepanel.com/project-case/horse-farm-fence]Horse farm Fence[/url] then squeeze
The surface quality have greatly improved.
