PET geotextile
문제 현상
PET geotextile strength decays rapidly in alkaline soil
원인 분석
PET has poor alkali resistance; the alkaline soil environment causes hydrolytic degradation of fibers and long-term strength loss; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Switch to PP geotextile in alkaline environments; limit PET geotextile to neutral environments and conduct alkali resistance verification; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Geotextile material selection must consider the soil chemical environment; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
