Matters needing attention in the test of melt flow index Tester

Abstract: 文章《熔体流动指数测试仪试验时的注意事项》详细讲述了在使用熔体流动指数测试仪时，确保测试结果准确的关键步骤。首先，测试前需对机器进行调平，以确保其垂直度，避免测试结果受到影响。调平过程中应使用铅垂线进行检查，并通过调整脚踏板来实现精确调平。再有就是测试后需要彻底清洁桶和孔口，以准备测试其他材料。清洁步骤包括将温度提高到高于测试材料熔点的水平，并使用随附的清洁工具清除残留物。这些措施不仅有助于获得准确的测试结果，还能有效维护设备的长期使用性能。

The melt flow index Tester is the mainstay of manufacturers in the plastics industry as it is the basic machine used to test the quality of plastic pellets, defining the quality of the material. Before starting a test procedure with a melt flow index Tester, certain things need to be considered so that the user can obtain accurate test results.

Machine leveling before testing

The machine should be leveled before starting the test procedure so that the user can obtain accurate test results.

  • To check the leveling of the machine, use the plumb line supplied with the machine

  • Remove the orifice die from the machine and insert the plumb wire into the barrel.

  • Now check the verticality of the plumb line in relation to the ground.

  • If the plumb line is perfectly perpendicular to the ground, the machine is fully leveled.

  • If the plumb line deviates slightly from vertical, it means the machine needs to be leveled.

  • Level the machine by aligning the foot pedals.

This procedure can help you perform melt flow testing. After performing a test, it is necessary to clean the bucket firmly so that the next test can be performed with a different type of pellet to

  • Get accurate results. This will also help you maintain your equipment efficiently over the long term.

Clean bucket after test

  • After you have finished testing one material and have another to test, the barrel and orifice need to be properly cleaned for accurate test results.

  • For barrel and bore cleaning, the temperature is raised above the melting point of the material being tested. The temperature should be raised by at least 10 C to 15 C. This will help loosen material stuck to the barrel walls or mold holes.

  • After raising the temperature, wait three to five minutes.

  • Now use the flat and threaded cleaning tool that came with your machine to clean the barrel and cavity of the cartridge.

  • Afterwards, the mold or orifice should be cleaned from the bottom of the bucket with an orifice cleaning tool.

  • After cleaning is complete, another material can be tested.

This process will help you maintain your instrument over time and help you test different types of particles time and time again with accurate results. have
