托幕线的优势 Advantages of supporting curtain line

　　托幕线，它作为铁丝及钢丝的最佳替代品。它相比于铁丝或者钢丝来说，价格比较便宜，而且不易上锈，重要很轻便甚至耐气候老化等优势。目前的托幕线主要有两种黑色和透明色，黑色托幕线主要用于葡萄园的支撑线，还可以用于温室外拉幕系统及室外遮阳棚，坐托压膜线之用。透明色托幕线主要用于室内部分金属结构的替代品。

Supporting curtain line, as the best substitute for iron wire and steel wire. Compared with iron wire or steel wire, it is cheaper, not easy to rust, important and light, and even weather aging resistance. At present, the supporting curtain line mainly has two kinds of black and transparent colors. The black supporting curtain line is mainly used for the supporting line of the vineyard, and can also be used for the pulling curtain system outside the greenhouse and the outdoor sunshade, as well as the supporting film line. Transparent color curtain line is mainly used as a substitute for some indoor metal structures.

　　当然目前托幕线的用途很广，主要用于葡萄种植、温室以及养殖业中。托幕线自从产生以来就迅速取代了很多钢丝或着铁丝的应用，在一定程度上也缓解了钢铁的使用。同时它相比于尼龙线，托幕线的拉伸率较低，因此能够很容易地迅速张紧，并且一旦被张紧，托幕线将保持这样张紧状态而不必重新再次张紧。托幕线也是一种耐温的产品，它在环境温度-40℃~70℃的情况下也可以保持其力学性能和几何尺寸不变。

　　总之，托幕线是一种完善其他产品不足但又其性能上更加完善的钢丝、铁丝或者尼龙线的替代品。

Of course, at present, the supporting curtain line is widely used, mainly in grape planting, greenhouse and aquaculture. Since the production of supporting curtain line, it has quickly replaced the application of many steel wires or wires, and also eased the use of steel to a certain extent. At the same time, compared with nylon wire, the tension rate of supporting screen wire is lower, so it can be easily tensioned quickly, and once tensioned, the supporting screen wire will remain in such a tensioned state without having to be tensioned again. Supporting curtain line is also a kind of temperature resistant product. It can also maintain its mechanical properties and geometric dimensions under the ambient temperature of -40 ℃ ~70 ℃.

In a word, the supporting curtain line is a substitute for steel wire, iron wire or nylon line that is not enough to improve other products but has more perfect performance.
