1、輕薄型薄膜、這種薄膜厚度只有普通薄膜厚度的一半，因此重量減輕一半，相應(yīng)的使用成本也降低一半。這種薄膜的透光度和保溫性能也優(yōu)于普通薄膜，但應(yīng)用在農(nóng)業(yè)生產(chǎn)中，回收起來(lái)比較困難。 2、多用途薄膜，福建透明薄膜工廠，福建透明薄膜工廠、此種薄膜除用做水稻、棉花，福建透明薄膜工廠、玉米、烤煙、花卉的育苗和大田覆蓋外，還可利用它做防洪膜，為灌渠和貯水池做內(nèi)襯，從而較大提高水的利用系數(shù)。因?yàn)楸∧?yīng)用的環(huán)境和條件不同，對(duì)薄膜的耐溫性有一定的要求。福建透明薄膜工廠</p><div

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(guò)程，并依靠空氣或水來(lái)冷卻定型。產(chǎn)品的定型時(shí)間過(guò)長(zhǎng)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(lái)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(méi)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(shì)在產(chǎn)品質(zhì)量上的體現(xiàn)，而流延法的加工設(shè)備通過(guò)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(wú)法解決的問(wèn)題。</p><p style="text-indent:25px">塑料薄膜廠家制作的薄膜采用的原料是聚乙烯，因此也被稱為聚乙烯薄膜，這一薄膜具有防潮性，透濕性小等優(yōu)勢(shì)，使用效果非常好，它是怎么從聚乙烯制作成薄膜的呢？在制作塑料薄膜的時(shí)候，需先將干燥的聚乙烯粒子加入下料斗中，靠粒子本身的重量從料斗進(jìn)入螺桿，當(dāng)粒料與螺紋斜棱接觸后，旋轉(zhuǎn)的斜棱面對(duì)塑料產(chǎn)生與斜棱面相垂直的推力，將塑料粒子向前推移；在推移的過(guò)程中，由于塑料與螺桿、塑料與機(jī)筒之間的摩擦以及粒子間的碰撞磨擦，還由于料筒外部加熱，從而逐步溶化。塑料薄膜廠家表示完成上述操作步驟以后，熔融的塑料會(huì)經(jīng)機(jī)頭過(guò)濾網(wǎng)去雜質(zhì)從模頭模口出來(lái)，經(jīng)吹脹、風(fēng)環(huán)冷卻之后經(jīng)人字板壓，由牽引輥卷取將成品薄膜卷成筒即成為我們常見的塑料薄膜。薄膜技術(shù)有比較普遍的應(yīng)用。</p><div

style="text-indent:25px">塑料薄膜的物理性能試驗(yàn)鑒別法： 1、撕裂強(qiáng)度試驗(yàn) 在薄膜一端用剪刀將薄膜切成一厘米長(zhǎng)的切口，然后用手撕裂，觀察薄膜對(duì)撕裂的抵抗力及裂痕的狀態(tài)。容易撕裂的薄膜有聚苯乙烯、玻璃紙、醋酸纖維素等薄膜。聚乙烯、聚酯、尼龍、聚丙烯等薄膜的撕裂強(qiáng)度大，但根據(jù)加工條件、增塑劑含量的不同而略有區(qū)別。 2、收縮性能試驗(yàn) 將薄膜緩慢接近火焰，不同種類的薄膜呈現(xiàn)出激烈收縮和不激烈收縮兩種狀態(tài)。收縮少的薄膜有聚酯、醋酸纖維素薄膜、硬質(zhì)聚氯乙烯（無(wú)增縮劑）、聚碳酸酯等薄膜，激烈收縮的薄膜有拉伸聚氯乙烯（熱收縮性聚氯乙烯）、拉伸聚丙烯、聚偏二氯乙烯、聚乙烯等薄膜。 3、延伸性試驗(yàn) 剪下一片長(zhǎng)10~15厘米、寬1厘米的帶狀薄膜，捏住二端慢慢拉伸，采用這種試驗(yàn)方法可以發(fā)現(xiàn)：延伸率大的薄膜有聚乙烯、未拉伸聚丙烯、軟質(zhì)聚氯乙烯、聚乙烯醇、鹽酸橡膠、未拉伸尼龍薄膜等，延伸率小的薄膜有普通玻璃紙、聚酯、醋酸纖維素、硬質(zhì)聚氯乙烯、聚偏二氯乙烯薄膜等，聚碳酸酯、拉伸尼龍的延伸率介于上述兩者之間。及時(shí)洗凈，這是塑料薄膜保管好壞的一個(gè)關(guān)鍵措施。福建透明薄膜工廠</p><p

1、分子結(jié)構(gòu)的非極性一般情況下，油墨和膠黏劑在塑料薄膜表面的吸附和黏合主要是靠?jī)烧叻肿娱g的作用力來(lái)實(shí)現(xiàn)的。大多數(shù)塑料薄膜包裝材料的分子結(jié)構(gòu)中基本沒(méi)有極性基團(tuán)或只帶有弱極性基團(tuán)，臨界表面張力小，惰性較強(qiáng)，是典型的非極性新型材料，油墨和膠黏劑對(duì)其表面的潤(rùn)濕性和親和性差，兩者分子間作用力非常弱。 2、塑料薄膜的表面能塑料薄膜的表面能通常是比較低的，如聚乙烯的臨界表面張力只有3.1×10-2N/m，聚丙烯的臨界表面張力只有3.4×10-2N/m，表面能低，不容易被油墨或者膠黏劑所潤(rùn)濕，因此，必須使塑料薄膜的臨界表面張力大于或等于油墨或膠黏劑的表面張力，以保證油墨或膠黏劑在其表面上得到充分的潤(rùn)濕。福建透明薄膜工廠</p><p
