        LLDPE的加工與應用

        文章出處:   責任編輯:   發布時間:2016-02-15 16:45:00    點擊數:-   【

        LDPE和LLDPE都具有極好的流變性或熔融流動性。LLDPE有更小的剪切敏感性,因為它具有窄分子量分布和短支鏈。在剪切過程中(例如擠塑),LLDPE保持了更大的粘度,因而比相同熔融指數的LDPE難于加工。在擠塑中,LLDPE更低的剪切敏感性使聚合物分子鏈的應力松弛更快,并且由此物理性質對吹脹比改變的敏感性減校在熔體延伸中,LLDPE在各種應變速率下通常都具有較低的粘度。也就是說它將不會象LDPE一樣在拉伸時產生應變硬化。隨聚乙烯的形變率增加.LDPE顯示出粘度的驚人增加,這是由分子鏈纏結引起。這種現象在 LLDPE中觀察不出,因為在LLDPE中缺少長支鏈使聚合物不纏結。這種性能對薄膜應用極重要.因為 LLDPE薄膜在保持高強度和韌性下召易制更薄薄膜。

        LLDPE的流變性可概括為“剪切時剛性”和“延伸時柔軟”。 當用LLDPE替代LDPE時薄膜擠塑設備和條件必須做修改。LLDPE的高粘度要求擠塑機有更大的功率.并提供更高的熔體溫度和壓力。??谙毒啾仨毤訉捯员苊庥捎诋a生高背壓和熔體斷裂而降低產量。 LDPE和 LLDPE的一般??谙毒喑叽绶謩e是O. 024~0. 040 in.和 0. 060-0. 10in。

        LLDPE的“延伸時柔軟”的特性在吹膜過程中是一個缺點。LLDPE的吹塑薄膜膜泡不象 LDPE的那么穩定。 一般的單唇風環對 LDPE的穩定足夠使用.LLDPE的特有的膜泡要求更完善的雙唇風環來穩定。用雙唇風環冷卻內部膜泡可增加膜泡穩定性,同時在高生產率下提高薄膜生產能力。除了膜泡的更好冷卻外,很多薄膜生產廠采用與LDPE共混方法以增強LLDPE溶道理上,LLDPE的擠塑可以在現有LDPE薄膜設備上完成,當LDPE的共混物中 LLDPE的濃度達 50%時。加工 100% LLDPE或富含LLDPE的與LDPE共混材料時,采用一般的LDPE擠塑機,必需改進設備。根據擠塑機的壽命,要求改進的可能是加寬??谙毒?,改良風環,修改螺桿設計以更好擠出,必要時應增加電機功率和轉矩。對于注塑應用,一般不需改進設備,但加工條件需達最佳化。 滾塑加工要求LLDPE研磨成均勻顆粒(35篩孔)。加工過程包括用粉末狀LLDPE填滿模具,加熱并雙軸向地旋轉模具使LLDPE均勻分布。冷卻后產品從模具中移出。

        LLDPE已滲透到聚乙烯的大多數傳統市場,包括薄膜、模塑、管材和電線電纜。防滲漏地膜是新開發的LLDPE市場地膜,一種大型擠出片材,用作廢渣填埋和廢物池襯墊,防止滲漏或污染周圍地區。LLDPE的一些薄膜市場,例如生產袋子、垃圾袋、彈性包裝物、工業用襯套、巾式襯套和購物袋,這些都是利用改進強度和韌性后這種樹脂的優點。透明薄膜,例如面包袋,一直由LDPE占統治地位,因為它有更好的濁度。然而,LLDPE與LDPE的共混物將改進強度、抗穿透性和LDPE薄膜的剛度,而不顯著影響薄膜的透明度。注塑和滾塑是LLDPE最大的兩個模塑應用。這種樹脂優越的韌性和低溫、沖擊強度理論上適于廢物箱、玩具和冷藏器具。另外,LLDPE的高抗環境應力開裂性使其適用于注塑與油類食品接觸的模塑蓋子,滾塑廢料容器、燃料箱和化學品槽罐。在管材和電線電纜涂敷層中應用的市場較小,在這里LLDPE提供的高破裂強度和抗環境應力開裂性可滿足要求。目前,LLDPE的 65%-70%用于制作薄膜。
