托幕線，它作為鐵絲及鋼絲的最佳替代品。它相比于鐵絲或者鋼絲來說，價格比較便宜，而且不易上銹，重要很輕便甚至耐氣候老化等優(yōu)勢。目前的托幕線主要有兩種黑色和透明色，黑色托幕線主要用于葡萄園的支撐線，還可以用于溫室外拉幕系統(tǒng)及室外遮陽棚，坐托壓膜線之用。透明色托幕線主要用于室內(nèi)部分金屬結(jié)構(gòu)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.

　　當然目前托幕線的用途很廣，主要用于葡萄種植、溫室以及養(yǎng)殖業(yè)中。托幕線自從產(chǎn)生以來就迅速取代了很多鋼絲或著鐵絲的應用，在一定程度上也緩解了鋼鐵的使用。同時它相比于尼龍線，托幕線的拉伸率較低，因此能夠很容易地迅速張緊，并且一旦被張緊，托幕線將保持這樣張緊狀態(tài)而不必重新再次張緊。托幕線也是一種耐溫的產(chǎn)品，它在環(huán)境溫度-40℃~70℃的情況下也可以保持其力學性能和幾何尺寸不變。

　　總之，托幕線是一種完善其他產(chǎn)品不足但又其性能上更加完善的鋼絲、鐵絲或者尼龍線的替代品。

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.
