PC料的特性及注塑工藝是什么?
PC性能優異,透明度較高,沖擊韌性好,耐蠕變,使用溫度范圍寬,PC的工藝特性是:熔融粘度對剪切率的敏感性小,而對溫度的敏感性大,無明顯熔點,熔融體粘度較高,
高溫下樹脂易水解,制品易開裂。針對這些特性,我們特別要注意區別對待:要增加熔體的流動性,不是用增大注射壓力而應采用提高注射溫度的辦法來達到。要求模具的流道、澆口短而粗,以減少流體的壓力損失,同時要較高的注射壓力。
樹脂在成型加工之前需進行充分的干燥處理,使其含水量控制在0.02%以下,此外,在加工過程中對樹脂還應采取保溫措施,以防重新吸濕。不僅需要合理的制品設計,還應正確掌握成型工藝,如提高模具溫度,對制品進行后處理等可以減少或消除內應力。視產品的不同狀況及時調正工藝參數。
成型工藝
1、注射溫度必須綜合制品的形狀、尺寸,模具結構。制品性能、要求等各方面的情況加以考慮后才能作出。一般在成型中選用溫度在270~320℃之間,過高的料溫如超過340℃時,PC將會出現分解,制品顏色變深,表面出現銀絲、暗條、黑點、氣泡等缺陷,同時物理機械性能也顯著下降。
2、注射壓力對PC制品的物理機械性能,內應力、成型收縮率等有一定的影響對制品的外觀及脫模性有較大的影響,過低或過高的注射壓力都會使制品出現某些缺陷,一般注射壓力控制在80-120MPa之間,對薄壁,長流程,形狀復雜,澆口較小的制品,為克服熔體流動的阻力,以便及時充滿模腔,才選用較高的注射壓力(120-145MPa)。從而獲得完整而表面光滑的制品。
3、保壓壓力及保壓時間保壓壓力的大小及保壓時間的長短對PC制品的內應力有較大的影響,保壓壓力過小,補縮作用小易出現真空泡或表面出現縮凹,保壓壓力過大,澆口周圍易產生較大的內應力,在實際加工中,常以高料溫,低保壓的辦法來解決。保壓時間的選擇應視制品的厚薄,澆口大小,模溫等情
況而定,一般小而薄制品不需很長的保壓時間,相反,大而厚的制品保壓時間應較長。保壓時間的長短可通過澆口封口時間的試驗予以確定。
4、注射速度對PC制品的性能無十分明顯的影響,除了薄壁,小澆口,深孔,長流程制品外,一般采用中速或慢速加工,最好是多級注射,一般采用慢-快-慢的多級注射方式。
5、模具溫度一般控制在80-100℃就可以,對形狀復雜,較薄,
要求較高的制品,也可提高到100-120℃,但不能超過模具熱變形溫度。
6、螺桿轉速與背壓由于PC熔體粘度較大,從有利塑化,有利排氣,有利塑機的維護保養,防止螺桿負荷過大,對螺桿的轉速要求不可太高,一般控制在30-60r/min為宜,而背壓控制在注射壓力的10-15%之間為宜。
7、PC在注塑過程中要嚴格控制脫模劑的使用,同時再生料的使用不能超過三次,使用量應為20%左右。
對生產PC制品的塑機要求:要求制品的最大注射量(包括流道、澆口等)應不大于公稱注射量的70-80%,螺桿選用單頭螺紋等螺距,帶有止回環的漸變壓縮型螺桿,螺桿的長徑比L/D為15-20,幾何壓縮比C/R為2-3。 。以上文獻若需轉載請備注出處:巴斯夫pbt //shanglikaiguan.cn/
