The tensile properties of rubber are one of the important indicators for rubber quality testing. Rubber production units and associated testing institutes are equipped with rubber tensile testing machines, the rubber tensile testing machines purchased from many manufacturers can do this however, do not meet the relevant requirements. Rubber tensile testing machines have relatively high requirements for electronic universal testing machines, so how should we choose a suitable rubber tensile testing machine?
First capital line(It is best over1.2meters)
Rubber material deforms greatly when stretched, generally more than 200%, especially for latex products, the elongation can be up to 1000%. That is, assuming a sample of 10cm, it can be stretched to 1m. The effective stroke of the general electronic universal testing machine is about 1.2m, so if you choose a rubber tensile testing machine, you should choose a machine select with a reach of 1.2 m or more For special patterns the manufacturer can adjust the raised version. Care must be taken to ensure that the gripper has enough travel before the rubber pattern breaks.
Second, high-precision and high-frequency data collection
The stretching force of the rubber material does not require much force, but the force value accuracy is high, and it is necessary to measure the force value with an accuracy of to obtain more than two digits after the decimal point.The rubber tensile strength test must display the corresponding deformation curves and force value changes throughout the elongation process, which requires a high-frequency data acquisition function of the testing machine.Generally, the data acquisition frequency of rubber tensile testing machines is 200 times per second above.
Third, accurate measuring and recording device(Configure extensometer for large deformations )
ThereforeThe rubber tensile test must be equipped with a measuring device that can accurately measure the deformation of the sample. It is called a large deformation extensometer in the industry. It is a necessary accessory for rubber tensile testing and can accurately measure the sample. Deformation amount.
Fourth, stress can be accurately described-strain curve
In the rubber tensile test, the stress value and the stress-strain curve associated with the gauge length must be displayed using special software and can draw different curves according to the test requirements, for example: the constant elongation stress of the specimen must meet the Measure the force value of the sample stretched to a given elongation while the constantte stress the sample stretched on given sample must measure force gauge. Using these charts, data analysis can be performed to determine whether the product's tractive performance parameters conform to relevant standards and use this as a basis for determining the quality of the product.
