1、長(zhǎng)壽薄膜、為使薄膜耐老化、易回收，在生產(chǎn)過(guò)程中加入防老化劑，可使薄膜的壽命延長(zhǎng)2～4倍。地膜在揭膜后仍有一定強(qiáng)度，回收后仍可使用，既降低了成本，又可減少田間的殘膜量。防蟲(chóng)薄膜、它是用普通乙烯和低密度乙烯制成的多層薄膜。這種膜只向四周反射陽(yáng)光中的紫外線，而阻止可見(jiàn)光的反射。害蟲(chóng)因忌怕紫外光而不敢靠近薄膜，故能起到防蟲(chóng)效果；對(duì)于防治抗藥性強(qiáng)的蚜蟲(chóng)、紅蜘蛛等特別有效。 2、防病薄膜、這是**薄膜，如玉米地膜、棉花地膜、瓜菜地膜等。它是利用不同作物具有專一性的病害而生產(chǎn)的。防病薄膜生產(chǎn)過(guò)程中，有針對(duì)性地加入某種特定的農(nóng)藥。這種地膜無(wú)殘留、無(wú)污染、防病效果明顯，廣西戶外耐候薄膜鍍鋅管，廣西戶外耐候薄膜鍍鋅管，不少地方已大量用于種植業(yè)。 3、除草薄膜，廣西戶外耐候薄膜鍍鋅管、除草薄膜是一種新興的農(nóng)用塑料薄膜，是普通地膜生產(chǎn)過(guò)程中加入黑色母?；蛘呋瘜W(xué)除草劑制成的。除草地膜可分為含除草劑的地膜和含陽(yáng)光屏蔽劑的除草地膜。半導(dǎo)體功能器件和光學(xué)鍍膜是薄膜技術(shù)的主要應(yīng)用。廣西戶外耐候薄膜鍍鋅管</p><div

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。而對(duì)于不透明塑料薄膜，比如白膜，則要求其白度高、不透明度好。甘肅自粘薄膜廠</p><p
