Description

A kind of gauze screen and its production technology
Technical field
The present invention relates to a kind of gauze screen and its production technology.
Background technology
Rail vehicle is in dither, the occasion of frequently micro stretching and compression protects what is laid using flexible nonmetallic tubing Cable.Laying cable has EMC Requirements, and originally conventional mode is to cover layer of metal housing outside plastic film capicitor again Pipe is solved.This mode need to be installed twice, and connector construction is complicated, easily causes and does over again.Outer layer metal shielded tube is in high frequency The lower inside and outside of vibration is easily worn and torn, and reduces electromagnetic compatibility shielding efficiency.
The advantageous feature of gauze screen is a lot, but there are some shortcomings, such as tensile strength is relatively low, and plasticity and toughness are very Difference.Tensile strength can be developed strong, plasticity and toughness are high, and it uses the more extensive gauze screen of scope, is technology of the invention Main points.
