The structure of the testing mechanism is as follows: the testing mechanism comprises a bracket, a displacement transmitting device is arranged on the bracket, one end of a sample is connected with the bracket, the other end is connected with the displacement transmitting device, and the displacement transmitting device is connected with a rotary code measuring device.
Description
Technical field
The utility model relates to a kind of percent thermal shrinkage mechanism for testing, can use simultaneously with pyrocondensation stress test mechanism.
Background technology
The pyrocondensation performance comprises pyrocondensation stress and percent thermal shrinkage, the power and the displacement that produce when needing to measure the sample pyrocondensation.The detection of past pyrocondensation stress and percent thermal shrinkage is carried out respectively, not only need multiple checkout equipment, and test efficiency is low, automaticity is low, also can't show the relation of pyrocondensation stress and percent thermal shrinkage in real time, and wherein the robotization of percent thermal shrinkage detection is maximum difficult point.Hinder the factor of percent thermal shrinkage automatic measurement to mainly contain following 2 points: contact method detects the weight or the friction force that need overcome displacement transducer self, and gravity or friction force all can't be ignored with respect to sample self pyrocondensation stress, therefore meeting disturbed test accuracy; The noncontact method detects the influence be subjected to temperature, displacement and sample self property (fast as contraction speed, shrinkage factor is high) and is difficult for realizing, and the noncontact method detects the cost costliness, is unfavorable for the popularization and application of checkout equipment.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of and has simple in structurely, easy to use, can carry out the percent thermal shrinkage mechanism for testing that the sample percent thermal shrinkage detects accurately and effectively.
