PPS Equipment Wear Protection
문제 현상
After several months of glass fiber PPS production, the screw and barrel wear, metering becomes inaccurate and black specks increase
원인 분석
PPS glass fiber grades are highly abrasive; Stellite alloy overlay welding is recommended for screw flights, and bimetallic (such as Xaloy 802 type) lining for the barrel; after wear, metering and plasticizing deteriorate simultaneously
해결 방법
①Select bimetallic lining for the barrel; ②Stellite overlay welding for screw flights; ③Establish a regular screw clearance inspection system; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Equipment protection for PPS glass fiber grades must be front-loaded; a bimetallic barrel plus Stellite flights is the long-life configuration; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
