Preparation and Testing of the Microstructure Diffuse Reflection Plate Based on the Continuous Extrusion

Abstract:

The article introduces a kind of preparation process of the micro structure diffuse reflection plate based on continuous extrusion and proposes a new preparation process of diffuse reflection plate. The process mainly includes two single screw extruders which work by means of co-extrusion composite. Then polymer sheet is got through the roller via the thermal printing. At last the micro structure is pressed on the polymer sheet. The preparation of diffuse reflection plate is successful. We can measure the surface microstructure of diffuse reflection plate by using ContourGT-X3 that is made from Germany. The content of the measuring includes the 3 d shape, depth, diameter and uniformity of the micro structure. The article analyzes that the die temperature, rolling depression and roll speed have the influence on the diffuse reflection plate replication rate. The experimental result shows that the die temperature has little impact on the replication rate; Along with the increase of roller press, diffuse reflection plate replication rate increases; Along with the increase of the roller speed, diffuse reflection plate replication rate reduces.
