Abstract
The invention discloses a steel cord glue permeation rate detection method, which comprises the following steps: taking a vulcanized cord test specimen block; after both ends of the vulcanized cord test specimen block are fixedly clamped in a sealed way, introducing gas with the set pressure into the test specimen block; then, cutting off a gas source; detecting the pressure in a gas passage after the set detection time, i.e. the cord glue permeation rate of the test specimen block can be determined through the ratio of the pressure in the gas passage to the initial gas pressure. The method has the advantages of simplicity, convenience, high speed, short time and high efficiency.
Description
Technical field
The present invention relates to a kind of steel cord glue permeation rate detection method and device.
Background technology
Steel cord and rubber adhesion are important indicators of radial, and the cord and the vulcanization of rubber need high permeability, thereby improve steel cord and rubber adhesion.Adopt hydraulic pressure bubble seepage method to detect cord glue permeation rate at present, it is by steel cord and vulcanization of rubber sample being passed to press water, the detection time through setting, detecting this sample water percolating capacity.Adopt this method long detection time, the water percolating capacity detection of complex causes accuracy not high.
Summary of the invention
The invention provides a kind of detection accuracy is good, efficient is high, easy to operate steel cord glue permeation rate detection method and device.
The present invention adopts following technical scheme: a kind of steel cord glue permeation rate detection method, get sulfuration cord coupon, behind the sealed at both ends clamping, pass to the gas of set pressure to coupon, cut off source of the gas then, after the detection time of setting, the pressure in the detected gas passage, the pressure in promptly can gas passage and the ratio of initial gas pressure are determined the cord glue permeation rate of coupon.
The present invention is by the pressure of test samples piece inlet end, determine the cord glue permeation rate of coupon with the inlet end pressure and the ratio of initial gas pressure, perhaps pass through the pressure of test samples piece outlet side, determine the gas damage amount of coupon with the outlet side pressure and the ratio of initial gas pressure, the pressure that feeds gas to described coupon is 0.1MPa, and be 1 minute the detection time of setting.
A kind of steel cord glue permeation rate pick-up unit, it mainly comprises source of the gas, gas passage, upper grip, lower chuck, described upper and lower chuck is oppositely arranged and is respectively equipped with inlet channel and outlet passageway, described inlet channel and outlet passageway are communicated with gas passage respectively, are provided with gas pressure detection unit in the gas passage.
Described upper and lower chuck opposite face is provided with groove, and described groove is communicated with inlet channel, outlet passageway respectively.Described pressure-detecting device is rain glass or digital pressure gauge.Described upper grip is fixed on the frame support arm, and lower chuck is installed on the gantry base, and both arrange up and down relatively.Described lower chuck is fixed on the gantry base by setting nut.
The present invention has following beneficial effect: steel cord glue permeation rate detection method, it is by passing to pressed gas to coupon, cut off source of the gas then, after the detection time of setting, gaseous tension in the detected gas passage, determine the cord glue permeation rate of coupon with the pressure in the gas passage and the ratio of initial gas pressure, this method is simple, and is convenient.Be 1 minute the detection time of coupon, and the time is short, the efficient height.
The steel cord glue permeation rate pick-up unit, it is made up of source of the gas, gas passage, upper grip, lower chuck, and is simple in structure.Can adjust distance between upper and lower chuck by setting nut, can be easily fixing coupon.Adopt the pressure in the gas pressure detection unit mensuration gas passage, visual result, accuracy height.
