聚甲醛(POM)是一種沒有側鏈、密度高、高結晶型的線型聚合物,具有優越的力學機能,優異的抗蠕變性和應力松弛本領,耐疲勞性是熱塑性塑估中是很高的,并具有突出的自光滑性、耐磨性和耐藥品性,是一種使用非常普遍的工程塑料。POM吸濕性小,加工前樹脂普通不需烘干。需要時,可在90~100℃下,烘干2~4h。POM的熔體粘度對剪切速度敏感。因此,要提升熔體活動性,不能單用提升溫度,也可從提升注射速度和注射壓力動手。POM是熱敏性塑料,240℃下會嚴重剖析。在210℃下。停止時段不能超出20min;縱然在190℃下,停止時段最好也不能超出1h。注塑時,在包管物料活動性的條件下,應只管選用較低的成型溫度和較短的受熱時段。POM具有相對顯著的熔點,共聚POM為165℃、均聚POM為175℃。成型時,料筒溫度的漫衍:前段190~200℃,中段180~190℃,后段150~180℃,噴嘴溫度為170~180℃。對薄壁制品,料筒溫度可恰當提升些,但不能超出210℃。模具溫度普通節制在80~100℃,對薄壁長流距及外形龐大的制品,模溫可提升至120℃。提升模溫有利熔體流功,避免因冷卻速度太快而使制品發生缺點,而且還可提升制品的打擊強度,但也提升了成型收縮率。注射壓力對POM制品的力學機能影響很小,但對熔體的活動性及制品的外面質量影響很大。注射壓力的大小,重要由制品的外形、壁厚、模具的流暢、澆口尺寸及模溫等而定。對小澆口、薄壁長流距、大面積的制品,注射壓力較高,為120~140MPa;而大澆口、厚壁短流距、小面積的制品,注射壓力為40~80MPa;普通制品為100MPa上下。恰當提升注射壓力,有利提升熔體活動性和制品外面質量,但壓力太高會造成制品溢料。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
