style="text-indent:25px">薄膜吹塑法和流延法的生產(chǎn)工藝比較： 1.流延法比吹塑法更加適合應(yīng)用于多層共擠的薄膜生產(chǎn)加工，尤其當(dāng)使用多種不同材質(zhì)的材料進(jìn)行共擠時(shí)，流延法的生產(chǎn)工藝參數(shù)更易于控制，加工設(shè)備的關(guān)鍵部分模頭的設(shè)計(jì)更能有效保證產(chǎn)品中各種材料分布的均勻性。而吹塑法的多層共擠模頭技術(shù)難度更大，結(jié)構(gòu)更為復(fù)雜且技術(shù)尚不夠成熟。 2.流延法的加工設(shè)備中，模頭至冷輥(成型至定型)的距離一般為10～20mm，熔膜簾比較短且在真空吸氣罩、氣刀及定邊裝置的幫助下比較快定型，產(chǎn)品質(zhì)量好且穩(wěn)定。而吹塑法由于熔膜有一個(gè)吹脹過程，并依靠空氣或水來冷卻定型。產(chǎn)品的定型時(shí)間過長且定型前的變化比較大(一般吹脹4～7倍)。 3.在原料的選擇上吹塑法和流延法也有較大差異，多層共擠時(shí)吹塑法要求盡量選用流動(dòng)性接近的材料來相互搭配，當(dāng)材料流動(dòng)性相差較大時(shí)，缺乏相應(yīng)措施進(jìn)行調(diào)整，因而當(dāng)選定了其中一種材料時(shí)，與其共擠的其他材料沒有多大的選擇余地，這在比較在程度上制約了多層共擠加工工藝優(yōu)勢在產(chǎn)品質(zhì)量上的體現(xiàn)，而流延法的加工設(shè)備通過對(duì)分流道的調(diào)節(jié)可以比較輕松解決吹塑法中幾乎無法解決的問題。</p><p style="text-indent:25px">塑料薄膜的表面張力取決于塑料薄膜表面自由能大小，而薄膜表面能又取決于薄膜材料本身的分子結(jié)構(gòu)。多數(shù)塑料薄膜如聚烯烴薄膜(LDPE、HDPE、LLDPE、PP)屬非極性聚合物，其表面自由能小，表面濕張力較低，一般為30達(dá)因/厘米左右。理論上講，若物體的表面張力低于33達(dá)因/厘米，普通的油墨或粘合劑就無法附著牢固，因此必須對(duì)其表面處理。聚酯類(PET、PBT、PEN、PETG)是屬于極性高的分子，其表面自由能較高，表面濕張力在40達(dá)因/厘米以上。但是對(duì)于高速彩色印刷或?yàn)樵黾诱婵斟冧X層與BOPET薄膜表面之間的結(jié)合力，也還需要對(duì)BOPET薄膜進(jìn)行表面處理，以進(jìn)一步提高其表面濕張力。塑料薄膜將空間分割成一個(gè)**密閉空間，將熱量保存下來，防止內(nèi)外界熱量交換。</p><div

style="text-indent:25px">電暈處理塑料薄膜表面濕張力的大小與施加於電極上的電壓高低、電極與電暈處理輥之間的距離等因素有關(guān)。當(dāng)然，電暈處理應(yīng)當(dāng)適度，并非電暈處理強(qiáng)度越高越好。這里值得注意的是塑料薄膜與電暈處理輥之間應(yīng)避免夾入空氣，否則有可能使薄膜的反面也被電暈處理了。反面電暈造成的後果是：1有可能產(chǎn)生油墨印刷的反粘現(xiàn)象；2在鍍鋁時(shí)會(huì)發(fā)生鍍鋁層轉(zhuǎn)移，在涂膠時(shí)會(huì)發(fā)生涂膠層轉(zhuǎn)移。防止薄膜反面電暈的主要措施是要調(diào)節(jié)好電暈處理輥前的橡膠壓緊輥的壓力，壓緊輥兩端壓力既要一致且壓力大小又要合適。另外，電暈輥和壓緊輥必須進(jìn)行嚴(yán)格的動(dòng)靜平衡試驗(yàn)，徑向跳動(dòng)要求小於0.05毫米，目的是保證塑料薄膜平整地進(jìn)入電暈輥、防止夾入空氣，從而避免發(fā)生反面電暈的現(xiàn)象。塑料薄膜的物理機(jī)械性能主要包括拉伸強(qiáng)度、斷裂伸長率、撕裂強(qiáng)度、沖擊強(qiáng)度等。四川高性能薄膜哪家好</p><p
