PCABS melt temperature window
문제 현상
PC/ABS melt temperature differences between 220-260℃ and 240-280℃, affected by grade and ratio.
원인 분석
PC/ABS melt temperature 220-260℃ (Sales Plastics) or 240-280℃ (Textileus); higher PC ratio, higher temperature; higher ABS ratio, lower temperature; degradation above 300℃; grade differences.
해결 방법
①Select temperature according to grade and ratio; ②take the upper limit for high PC ratio; ③avoid exceeding 300℃; ④measure actual melt temperature; ⑤temperature gradient management.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
The ratio dependence of PCABS melt temperature is a material characteristic; 300℃ is the degradation red line; actual measurement prevents display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
