PP Geotechnical Material Application
Problem Phenomenon
【Problem Phenomenon】Geotextiles and geogrids need chemical resistance and aging resistance
Cause Analysis
PP geotextiles and geogrids are chemical-resistant and aging-resistant, and are widely used in civil engineering; weather-resistant modification ensures long-term performance; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
Select weather-resistant PP for geotechnical materials; strength according to the project; aging life verification; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PP geotechnical materials are aging-resistant, commonly used in civil engineering; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
