环状挤出机连续挤出工艺的突出优势

Advantages of annular extruder extrusion process

测试胶管的使用寿命和故障源首先需要确定胶管的使用时间、温度和压力,在开始测试前应确定其性能、主要功能和关键条件。简介了胶管测试的4种方法(压力、流体相容性、热老化和振动)的基本情况。

To test the service life and fault source of the hose, it is necessary to first determine the use time, temperature and pressure of the hose. Before starting the test, the performance, main function and key conditions should be determined. The basic conditions of the four methods （pressure, fluid compatibility,thermal aging and vibration） of the hose test are introduced.
