PVDF Cable Sheath Surface Smoothness Improvement
문제 현상
【Problem Phenomenon】The PVDF cable sheath surface is matte and rough, failing appearance acceptance by high-end customers
원인 분석
The surface smoothness of the sheath is directly related to die temperature, melt uniformity and processing additives; Arkema points out that raising the die to 260℃ can smooth the surface but requires short residence time, and EXAD additives can also improve it
해결 방법
Cautiously raise the die temperature to 260℃ and confirm short residence time in the die; add EXAD 3000 or similar additives to improve the surface; simultaneously check melt filtration and mixing uniformity
핵심 요약
The sheath surface relies on the dual means of high die temperature plus additives, on the premise of short residence time; 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 subsequent similar problems
