MS Suspension Polymerization Preparation
문제 현상
MS suspension polymerization preparation process, monomer refining and initiation.
원인 분석
MS suspension polymerization preparation; monomers styrene and methyl methacrylate are purified by alkali washing and redistillation in advance; initiator benzoyl peroxide recrystallized; nitrogen protection; temperature control; bead quality.
해결 방법
①Monomer refining; ②initiator purification; ③nitrogen protection; ④temperature control; ⑤bead quality.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Refining and protection in MS polymerization preparation are the quality foundation; process control ensures performance; management ensures stability.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
