Glass Fibre hardness too high
ظاهرة المشكلة
Glass Fibre product Shore hardness 5-10 degrees higher than target, feels hard
تحليل الأسباب
Glass Fibre crystallinity too high, rigidity increased; filler added too much; cooling too fast, crystallization imperfect but rigidity frozen
الحل
1) Reduce cooling rate to make crystallization complete and reduce hard feel; 2) reduce filler addition; 3) add plasticizer 0.5wt% to reduce hardness
الخلاصة الأساسية
High hardness is caused by crystallization and filler; adjusting cooling and filler is key
