Material surface test sample table with accuracy improvement function

Abstract

The invention discloses a material surface test sample table with an accuracy improvement function. The material surface test sample table comprises a sample placing table, an inverted T-shaped sampleclamping groove penetrates two ends of the sample placing table and is formed in the surface of the sample placing table, a movable supporting plate is arranged at the bottom of the sample clamping groove, the bottom surface of the movable supporting plate is connected with the bottom of the groove through a sliding groove and a slider, the movable supporting plate can horizontally move along thesample clamping groove back and forth, a limit strip is parallelly arranged at the bottom of the sample clamping groove beside the movable supporting plate, the height of the limit strip is matched with that of the bottom of the groove, a flange is arranged at one end, far away from the limit strip, on the movable supporting plate, and the height of the flange is matched with the thickness of a sample to be tested. A fixing device of the sample table can effectively fix the sample to be tested, shooting of droplet shapes on the surface of the sample cannot be affected, so that the sample canbe rapidly positioned on the lower portion of a dropping pipe, and detection efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to a clamping device, in particular to a material surface test sample platform with improved accuracy. Background technique [0002] The contact angle refers to the angle θ between the tangent line of the gas-liquid interface made at the intersection of gas, liquid and solid, passing through the liquid and solid-liquid boundary line, which is a measure of the degree of wetting. The contact angle is an important parameter to characterize the surface properties of materials. The main method is to use a contact angle tester to measure it. Put the sample to be tested on the sample stage, then titrate the test solution to the surface, and finally measure the formation of droplets on the surface of the sample. The included angle was calculated to obtain the contact angle. However, the existing contact angle tester directly places the sample on the plane of the sample stage without any fixed structure to fix the sample, so it is easy to...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing contact angle tester directly places the sample on the plane of the sample stage without any fixed structure to fix the sample, so it is easy to cause the sample to move during the operation, thus affecting the liquid contact angle. The shape of the droplets falling on the surface of the sample affects the test accuracy. The purpose is to provide a material surface test sample platform with improved accuracy, which can play a good role in fixing the sample to be tested, and will not affect the shape of the droplet on the sample surface. Shooting, so that the sample can be quickly positioned under the dropper, improving detection efficiency
