UPDATE:2013-06-04 16:33:56  HITS:0

      Nylon cable tie winter fracture how to do, we're going to talk about. Arrived in the winter, we all know that plastic this thing in the winter will become very brittle, because the main ingredient of plastics is a large molecular aggregates, characteristics of large molecules is the slow motion at low temperature, high temperature movement speed. In the winter time, the molecular motion is slow, the deformation of an object when the plastic by outside force, slow, because of molecular motion, force is not easy to pass away (both internal stress) or off (molecular chain friction), so easy to produce stress concentration, when the stress to a certain extent, the large molecule is broken, crack initiation, crack can cause stress concentration and propagation, plastic is broken. 

      The solution: general small amounts of water can reduce the fault injection in the bag.
