Compression bar, support annulus, circular ring shape clip are metal material.
A kind of instrument of the creep resistance of above-mentioned measurement plastic film when in use, by the surrounding of plastic film sample
Along encasing support annulus and tightening, it is then charged into circular ring shape clip, tightens fastening bolt, so that circular ring shape clip banding plastics
The surrounding edge of film sample, so that the surrounding edge of plastic film sample be fixed.By the bulb of bulb compression bar from upper past
Under be pressed in plastic film upper surface middle part so that bulb compression bar is pressed in the upper table of plastic film under the gravity of counterweight
The middle part in face, round tube play the guiding role to moving up and down for bulb compression bar, write down the reading of amesdial.After spending the regular hour,
The reading of amesdial is write down again.According to bulb compression bar in initial position the reading of amesdial and cross the regular hour after amesdial
Reading, the displacement that counterweight and bulb compression bar move down can be obtained.This moves down the plastic film that displacement namely measures
Within this regular hour, under the effect of the pressure of counterweight and bulb compression bar, the Creep Deformation amount of plastic film.Plastic film exists
Creep Deformation amount in this regular hour is smaller, illustrates that the creep resistance of the plastic film is better.
Compared with the prior art, the present invention has the following advantages:
1, the present invention can accurately measure plastic film sample in a timing using amesdial come the upper and lower displacement of measure-ball compression bar
Interior Creep Deformation amount, from the creep resisting ability that can measure plastic film.
2, bulb compression bar of the invention can take out from round tube, and counterweight can be removed from bulb compression bar, so that of the invention
The components of creep resistance tester are reloaded into packing box after can dismantling, and compact structure of the invention, light, so that this
It is easy to carry to invent the creep resistance tester provided.
3, the present invention is easy to use, is easy to test operation, is conducive to promote the use of.
4, the configuration of the present invention is simple, design rationally and be simple to manufacture, be conducive to promote the use of.
Below by drawings and examples, the present invention is described in further detail.
