当前位置:登山使用的绳子也非一般的绳子
[来源:www.syuan-lab.com] [作者:aywl] [日期:17-05-03]
登山使用的绳子也非一般的绳子,经常使用登山绳做一些攀登或其他训练,但是当问到一些关于绳索的细节问题时,往往一点也不了解或者知道也是一知半解,更好、更安全的使用绳索,使它成为救援中的好助手!下面就给大家介绍四种最常使用的天然纤维制造的绳子:   一、马尼拉麻,来自一种麻焦的茎,这种植物是香焦近亲。早期的登山航海等活动都用此类绳索,1864年英国登山俱乐部选定直径十毫米,每米重量为75克的马尼拉麻为登山首选用绳,这咱绳子的强度几乎跟现在登山用绳的强度一样,而且遇水湿后会更结实。   二、 剑麻,主要用来制作价格便宜的绳子,它的强度比马尼拉麻低20%,柔顺度也差一些。   三、 印度、意大利大麻纤维,这种天然纤维强度高适用于航海。但要经过焦油处理才能保持其在海水中的耐久性,后来多转用马尼拉麻,但意大利麻一直是登山的常用绳材料。   四、 其他纤维,黄麻、槿麻、亚麻、耶壳纤维、棉花都可以制作绳索,但强度不高,不适合用做登山用绳。值得一提的是椰壳纤维是唯一一种可以在水上漂浮,并耐海水腐蚀的天然纤维。还有一种是天然橡胶,有着超强的延伸性(300%),所以应用做为减震绳非常合适,如蹦极绳。   以上四种就是比较常用的自然纤维的绳子,可以对比按照需要或者使用习惯,进行选择使用,各有优势。 Rope climbing the rope also unusual, often used in mountaineering to do some climbing or other training, but when asked about some details about the rope, often do not know or know is also a little knowledge, better and safer to use ropes, make it become the good assistant of our rescue! Below to introduce four of the most commonly used natural fiber rope manufacturing: a, Manila hemp, stems from a ZhongMa coke, this plant is a banana first cousin to a lie. Early mountaineering activities such as sailing with such ropes, in 1864, Britain's the mountaineering club selected 10 mm in diameter, weight of 75 grams per meter of Manila hemp rope for mountaineering preferred, the intensity of za rope almost like now climbing with the strength of the rope, and stronger when exposed to water wet. Second, the sword hemp, mainly used to make the price cheap rope, its intensity is 20% lower than the Manila hemp, and the softness is also inferior. Three, Indian, Italian hemp fiber, this natural fiber strength is good for sailing. But it will be treated with tar to retain its durability in the water, and later in Manila hemp, but the Italian hemp has always been a staple of climbing. Four, other fiber, the jute, the hibiscus, flax, the case fiber, the cotton can make the rope, but the intensity is not high, is not suitable to use to make the climbing rope. It is worth noting that coconut fibre is the only natural fibre that can float on water and withstand the erosion of seawater. Another is natural rubber, which has a strong extensibility (300%), so it is perfect for a shock rope, such as a bungee cord. The above four kinds of natural fibers that are more commonly used, can be compared according to the need or use the habit, make the choice to use, each have the advantage.
