我厂轮胎胎面挤出采用两台ＸＪ 2 0 0型挤出机。随着产量不断增加 ,挤出速度不断提高 ,挤出速度提高后 ,挤出生热、变形增大 ,随之产生胎面熟芯、气孔和尺寸不稳定等质量问题 ,对轮胎内、外质量影响较大。本文针对这些质量问题进行原因分析 ,并提出相应的改进措施。1 原因分析
I plant tire tread extrusion using two XJ200-type extruder. With the continuous increase of output, the extrusion speed is continuously increased. After the extrusion speed is increased, heat generation and deformation are increased, resulting in quality problems such as tire core, stomata and size instability, affecting the tire inner and outer quality Larger. In this paper, the reasons for these quality problems are analyzed and the corresponding improvement measures are put forward. 1 reason analysis
