托幕线：
Plasteel wire(S.L.WIRES.塑钢线，托幕线Black and white string)
产品说明：
(1)、产品名称：托幕线、压幕线、塑钢线或压膜线。
（2）、主要用途：托/压幕线广泛应用于现代农业、温室、园艺等工程中，主要用于温室内、外的托/压遮阳覆盖材料。压幕线用于温室外遮阳网的拉幕系统，起压幕作用；托幕线用于温室内遮阳网、保温幕的拉幕系统,起托幕作用。产品还可作为挂苗吊线以及葡萄园的支撑线使用，是替代铅丝和钢丝等金属制品的理想材料，同时还可以应用于水产养殖以及蓄水池等。聚酯托/压幕线具有抗紫外线老化、高强度、低拉伸、热稳定、防酸防潮、表面光滑、环保等技术特性，使用更长久、更安全。
2-1、 黑色托幕线主要用于温室外拉幕系统及室外遮阳棚，做压膜线之用。产品还用于葡萄园的支撑线。
2-2、透明色托幕线用于温室内拉幕系统及室内遮阳棚,替代金属结构制品做托膜线之用。
（3）、技术参数：黑、乳白、透明色椭圆直径1.5-3.5mm，抗拉强度( N )≥2200， 断裂伸长率17.5%。
3－1、拉伸特性：聚酯托幕线的拉伸率较低，能够很容易地被迅速张紧，并且一旦被张紧，托幕线将保持这种张紧状态而不回弹。
3－2、高强度性：聚酯托幕线的结节强力黑色托幕线超过950N；透明色托幕线超过710N，因此更能抵挡住外界恶劣气候（如8～10级大风）带来的破坏性影响。
3－3、热稳定性：聚酯托幕线在环境温度－40℃～70℃的情况下，其机械性能和几何尺寸保持不变。
3－4、抗UV稳定性：在超过30个月的室外使用测试中表明，透明色托幕线的抗拉伸强度降低不到3％，黑色托幕线的强度降低更少，这就意味着托幕线在各种温室条件（玻璃、塑料薄膜等）和室外条件下使用寿命很长。
3－5、防酸性：由于原材料本身具此特征，因此聚酯托幕线能耐气候老化，更延长了其使用寿命。
3－6、永久光滑性：聚酯托幕线不吸湿，多年使用后，其表面依然光洁如初，没有毛刺出现。托幕线的表面光洁性对其所承托的遮阳保温幕具有积极作用，避免了对遮阳保温幕的磨损。
3－7、环保性：聚酯托幕线无腐蚀性、无污染性，起到保护环境的作用。
Plasteel wire(S.L.WIRES，support line,Black and white string)
Product Description:
1-1Product Name: plasteel wire, pressure screen wire, steel wire or laminated line.
1-2Technical parameters: black, white, transparent color oval diameter of 1.5-3.5mm, Tensile strength (N)≥2200, 17.5% elongation at break.
2-1 Black support line is mainly used to the greenhouse and outdoor awning pull screen system, making use of lamination lines. Product line is also used to support Vineyard.
2-2 Transparent color screen care line pull-screen system for greenhouse and indoor awning to replace the metal structure products, film lines made with care.
3-1Tensile properties: tensile polyester cord care lower screen can easily be tensioned quickly and once tension, supporting screen status line will not rebound to maintain this tension.
3-2 High strength: polyester screen line care strong black nodules screen care is over 950N; transparent color screen care line more than 710N, thus better withstand the weather outside (such as strong winds 8 to 10) brings the devastating impact.
3-3Thermal stability: polyester screen line care ambient temperature-40℃~70℃of the cases, the mechanical properties and geometry remain unchanged.
3-4UV stability: in more than 30 months of outdoor tests showed that the transparent color screen care line tensile strength decreased less than 3%, the black line of lower intensity care less screen, which means With care in a variety of greenhouse curtain line (glass, plastic film, etc.) and outdoor conditions, life is very long.
3-5Anti-acid: As the raw material itself, with this feature, so polyester curtain line capability weathering care, but also extend its service life.
3-6Permanent smoothness: polyester screen line is not moisture care, for many years after use, the surface is still smooth as ever, there is no glitch appears. Care screen line by supporting the smooth surface of the sun to its positive role in thermal screen, avoiding the heat of the sun screen wear.
3-7Environmental protection: polyester screen line of non-corrosive care, non-polluting, protect the environment.
