Polyolefin plastomer polyolefin plastomer processing equipment maintenance insufficient (Variant: Enhanced Measures)
Problem Phenomenon
Equipment failures occur frequently, product quality fluctuates, and production efficiency is low.
Insufficient maintenance causes equipment accuracy to decline, plasticization quality to deteriorate, and energy consumption to increase.
In particular, additional attention is needed on the original basis; this problem is more prominent and requires focused attention.
Cause Analysis
（1）The equipment has been running for a long time without periodic maintenance
（2）The wear of the screw and barrel is not inspected and replaced in time
（3）The mold is not regularly maintained and polished
（4）The sensors and instruments are not regularly calibrated
（5）The lubricating oil is not replaced on time, and the mechanical parts are worn
（6）On the original basis, additional attention is needed: fluctuations in process parameters or changes in equipment status have aggravated this problem
Solution
（1）Establish an equipment preventive maintenance plan, with monthly, quarterly, and annual maintenance
（2）Regularly check the screw gap (not exceeding 0.2mm) and barrel wear
（3）Perform maintenance and polishing on the mold every 100,000 mold cycles
（4）Calibrate the temperature sensors and pressure sensors every quarter
（5）Establish equipment files to record maintenance history
（6）And strengthen process monitoring; on the original basis, additional attention is needed to pay special attention to parameter stability
Key Takeaway
Equipment maintenance is the foundation of stable production, and a standardized regular maintenance system and record system need to be established.
Targeted preventive measures need to be taken in different production scenarios.
