Today we will talk about what is PVC sheet extrusion line .You may not be familiar with extrusion machine or PVC(Poly vinyl chloride).But around you all kinds of building ,you may find some of house from its roof ,wall ,flooring ,door are made from PVC or PVC compounding .
This stability building material come from PVC powder or PVC granule .Through the extruder ,shaping from die , cooling from downstream equipment ,then we get the end product .Below is its application.
Let's introduce several PVC sheet extrusion line to you from Polytech palscit machine company which have 27year experience of extrusion.
Let's see the composing of PVC sheet extrusion line .Here are photo show you .
Keeping the sheet thickness is very important .Sheet thickness is controlled by adjusting the flow from the die or adjusting the gap between the rolls.The temperature of the roll must balanced to have the best surface and fast cooling.Differences in roll temperature lad to warping or curling as well as residual stress .
Why do we choose PVC sheet extrusion machine? There are some advantages show you below.
1 Relatively cheep and versatile of material
2Broad range of rigid and flexible applications .
3High compatibility with additives and good processability.
4High output rate.
