MS Melt Temperature
Problem Phenomenon
Improper MS melt temperature, 210-270℃ range and air shot verification.
Cause Analysis
MS melt temperature 210-270℃ can be measured by the air shot method; specifics depend on supplier data; temperature affects flowability and degradation; actual measurement verification; grade differences.
Solution
①Melt temperature 210-270℃; ②air shot method verification; ③supplier data reference; ④measure actual melt temperature; ⑤grade differentiation.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Air shot verification of MS melt temperature is a practical method; supplier data is a reference; actual measurement ensures accuracy.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
