Description

Technical Field

[0001] The utility model relates to the technical field of tensile strength testing of dental adhesives, and more specifically, to a guided tensile testing device for dental adhesives. Background Art

[0002] Adhesives are widely used in tooth restoration. The performance evaluation of dental adhesives mainly involves the determination of hard tissue bonding strength. Bonding strength is one of the most important indicators in the development process of dental adhesives. Testers usually use tensile testing equipment to test the strength of adhesives.

[0003] Existing tensile testing devices generally have no guide rods, and there is no lateral restraint when the test pieces are stretched and separated from each other. The measured bond strength value is low, and the fracture of the sample shows the characteristics of material bending fracture.

[0004] The Chinese patent with patent application number CN201320863201.5 discloses a dental adhesive strength test fixture. The fixture is used in conjunction with a universal testing machine through a universal testing machine connecting shaft, which greatly reduces the cost of using a micro-tensile tester alone and expands the function of the universal testing machine; the bonded sample is pressed by double nuts and gaskets, and there is no need to use adhesives to stick the bonded sample to the test bench; when cutting the bonded sample, ensure the flatness of the bonding surface, and then directly cut it into small pieces according to the required size, which can avoid stress defects in the bonded sample during cutting; the test fixture is stable, easy to use, simple in structure, and very low in cost. The use of a guide rod makes the bonding strength test result more accurate;

[0005] Then, combined with the drawings in its specification, it can be seen that the fixture clamps and fixes the two ends of the two bonded samples, and realizes the guided tensile strength test by pulling. The clamping and fixing are driven by bolts, and the fixing efficiency is slow, which makes it inconvenient to place and remove. After the test is completed, it is inconvenient to separate the two bonded samples and it is inconvenient to clean the residual adhesive on the surface of the samples, which is inconvenient for continuous testing.
