当前位置:如何选择适合的绳子
[来源:www.syuan-lab.com] [作者:aoutmy] [日期:17-09-04]
第一步:决定基本的需求条件 低弹性绳VS。弹性绳[LowElongationVS。Dynamic] 低弹性绳只提供些微的延伸量,一般用在洞穴探险、垂降、搬运等不可能发生长距离墬落的活动。 单绳VS。双绳[SingleVS。DoubleRope] 单绳的直径从9。8mm到11mm,绳头的贴布上会标示,表示可以单独使用一条绳子。 双绳(也可称为半绳)的直径从8。2mm到9mm,绳头的贴布上会标示,表示需要同时使用两条一样规格的绳子。 防水绳VS。非防水绳[DryVS。Non-dryRope] 当绳子浸水后,会变得更重而且吸收墬落力量的效果降低。此外,在冰冻的情况下,绳子因吸收水分而结冻僵硬,弹性变差难以操作。 有防水处理的绳子,能有效减少绳子吸收水分的速度,保持较佳的弹性及较轻的重量。不过防水绳并非百分之百防止水分吸收,且表面的防水剂会随着使用次数增加而逐渐失效。 第二步:考虑绳子本身的基本数据 直径: 一般而言,绳子的直径愈粗,它的强度愈佳,也比较耐久。 长度: 绳子愈长,可供使用的地方也愈大,但较短的绳子重量较轻且方便携带。 Step 1: determine the basic requirements for low elastic rope VS. Elastic rope [LowElongationVS. Dynamic] low elastic rope provides only slight elongation, generally used in caving, rappelling, handling impossible distance down the activities of growth. Single rope VS. Double rope [SingleVS. DoubleRope] single rope diameter from 9. The 8mm to 11mm will be marked on the cord cloth to indicate a rope can be used alone. The diameter of a double rope (also called a half rope) is 8. The 2mm to 9mm will be marked on the end of the cord to indicate the rope to be used at the same time as two. Waterproof rope VS. Non waterproof rope [DryVS. Non-dryRope] when the rope after immersion will become heavier and absorbed down power effect. In addition, in frozen cases, the rope is frozen and stiff because of moisture absorption. It is difficult to operate because of the poor elasticity. Waterproof rope, can effectively reduce the rope to absorb moisture speed, and maintain better flexibility and light weight. However, waterproof rope is not one hundred percent to prevent moisture absorption, and the surface of the waterproof agent will gradually increase with the use of gradually invalid. The second step: consider the basic data diameter of the rope itself: Generally speaking, the thicker the diameter of the rope, the better the strength and durability of the rope. Length: the longer the rope, the greater the available place, but the shorter rope is lighter and easier to carry.
