POM塑料成型特性分析:
1)熔點明顯:POM是一種高密度,高結晶度的線型聚合物,具有明顯的熔點。
2)高結晶度和大體積收縮率:POM的結晶度高達70%至80%,并且在成型時熔化時需要吸收大量的熱量。當熔融物從熔融態冷卻到固態時,其體積收縮率大于其他塑料(當熔融物在室溫下從熔點以上的30℃冷卻至25℃時,比容變化為21)%),因此在處理厚壁時制成產品時,必須適當補縮。
3)熱穩定性差:POM在240℃會嚴重分解,顏色會變成黃色。在210℃下,停留時間不能超過20分鐘。在保證成型過程中物料流動的前提下,應盡可能采用較低的成型溫度和較短的成型周期。
4)固化速度快:POM的固化溫度約為160℃,固化速度快于熔融速度,因此可以快速脫模并縮短冷卻時間。由于固化速度快,產品表面容易出現流痕,焊接痕跡等缺陷,在加工過程中應采取相應的措施。
5)吸水率低:POM的吸水率約為0.25%,水分的存在對其性能和成型工藝影響很小,因此成型前可能不會干燥,而是當顆粒表面吸附水分時,它將改善產品。從外觀上看,它仍然需要干燥。6)流變性:POM的熔體粘度對溫度不太敏感,并且對剪切應力的依賴性更大。因此,要增加其流動性,不是從處理溫度起,而是從注射速度起。改善模具結構,控制模具溫度等方面。
7)加工流動性:高熔體質量流速的樹脂具有良好的流動性;溫度升高,流動性增加;注射壓力增加,流動性增加。當產品不足時,首先應通過增加注射壓力而不是注射溫度來解決;產品壁厚增加,澆口尺寸增加,流動長度也顯著增加。因此,當調整工藝條件時,無法改善熔體的流動性。請考慮適當修改產品或模具設計,以增加產品壁厚或擴大澆口尺寸。 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
