为了合理使用无滴长寿薄膜、延长使用寿命、提高保温效果,降低成本,无滴大棚膜在使用时要做到“五防”。 1.压好膜线防风害 薄膜既轻又薄,最怕被风吹掉和吹破。因此,棚膜一经扣上,就要用压膜线压住,一般每隔1米拉一层压膜线(采用圆形截面的钢丝芯或扁形截面的尼龙芯)。压膜线的松紧要适主,避免过松或过紧。 2.合理拼接防脱缝 多数大棚薄膜由窄宽幅拼接而
In order to make proper use of non-dripping long-life film, prolong the service life, improve the insulation effect and reduce the cost, the drip-proof greenhouse film should be “five defenses” when it is used. 1 pressure good film line windproof film both light and thin, most afraid of being blown and blowing broken. Therefore, once affixed to the greenhouse film, it is necessary to suppress the pressure with a film line, usually every 1 m pull a layer of film line (with circular cross-section of the core or flat cross-section of the nylon core). Laminate tight elastic film to be appropriate, to avoid too loose or too tight. 2. Reasonable stitching anti-off seam Most of the greenhouse film spliced by the narrow width
