The Principle of Lubricant usage

2020-08-21
The mature lubrication system should be beneficial to reduce the viscosity of the high temperature Polyvinyl Chloride melt, improve the fluidity of the material, and reduce the friction between the material and the equipment,and facilitate the processing of the pipe material.On the other hand, excessive lubricant should be avoided to delay the plasticization of the material, and low the degree of plasticization.

Different PVC RESIN, fillers,stabilizers and lubricants are used in PVC pipe in different production plants.In addition, the difference in pipe specifications, the difference between the extruder and the extrusion die also requires the lubricant to make an appropriate amount of adjustment. The amount of lubricant should follow the following principles:

1.The internal lubricant should be increased appropriately if PVC Resin powder has high degree of polymerization.

2.When using a composite STABILIZER containing a lubricating component, the lubricant should be appropriately reduced.

3.Internal and external lubrication in the formulation should be balanced to avoid processing difficulties.

4.If Pvc Resin powder is poor stability, the number of stabilizers should increases and the lubricant should be appropriately reduced.

5.When adding more filler, the lubricant should be increased appropriately.

6.When the processing temperature is high and the polymer is easily bonded to the processing equipment,the lubricant should be appropriately increased.

7.When using larger processing equipment, the surface of the polymer bond will increase and the lubricant should increase.

8.Excessive lubricant will reduce the plasticization of the material and weaken the mechanical properties of the pipe.
