Extruder test report

Wuhan Yincai Technology Co.,Ltd | Updated: Nov 22, 2017

Extruder test report

1 Introduction:

Extruder can control the parameters of two, one extrusion temperature, the second is the speed, the adjustment of these two parameters of different varieties of powder whether we have been tested, we were tested high light powder, extinction powder, Chemical extinction powder, now the test results are listed below, with a view to the production of powder plant to provide some reference. Experiment is used in Yantai Tung Fai 30A extruder (speed 0-300 rpm).

2 experiments and results

2.1 high light powder in the effect of different extrusion temperature,the same white material with the same speed 90-100,100-110,110-120,120-130 ℃ four temperature extrusion.

Note: The experiment using Hengyuan epoxy, France 5086 polyester, Xinji precipitated barium sulfate, the extruder speed of 210 rpm (frequency converter 35).

Experiments show that different extrusion temperature of high gloss powder, leveling no significant effect.

Experiments show that different speeds have no significant effect on the gloss level of high gloss.

2.3 Extinction of physical extinction powder at different temperatures under the effect of the same white material with the same speed (speed of 210 rev / min) were 90-100,100-110,110-120,120-130 ℃ four temperature extrusion .

Note: The experiment using Hengyuan epoxy, Beside 9801 polyester, ultra-fine barium sulfate, Wuhan Yin Cai 2031 physical matting agent, extruder speed of 210 rpm (frequency converter 35).

Experiments show that as the extrusion temperature increases, the gloss decreases.

3 Conclusion

3.1 speed, extrusion speed of the three tested powder no significant effect.

3.2 temperature, the extrusion temperature of high light, 68 extinction powder no significant effect, but the physical extinction powder with extrusion temperature increased gloss decreased.
