Further, on described upper connector and upper examination post, all offer the rectangle slotted eye, the upper end of described iron chains is arranged on by pin in the rectangle slotted eye of upper connector, and the interior latch one that passes through of rectangle slotted eye that its lower end is located at the examination post is connected with upper examination post.
Further, be equipped with gap between the both sides of the rectangle slotted eye of described iron chains and upper connector and upper examination post.The iron chains angle that left and right adjusting is certain voluntarily in the tension test process guarantees the pulling force concentric.
Further, described lower examination post is connected with lower connector by latch two.
Further, described upper examination post, sample and lower examination post are by viscose agent bonding.
The utility model job step is as follows:
A. upper and lower examination post is first cleaned out the thing of surface attachment before use, then uses sand paper sand hair, then uses the solvent scouring oil removing;
The coating of b. testing position is cleaned, oil removal treatment;
C. adhesive is coated in equably to upper and lower examination post surface, upper and lower examination post is sticked in tested overlay film or coating position, guarantee that upper and lower examination post and overlay film or coating surface of contact all sites have adhesive to adhere to;
D. with the fixing upper and lower examination post of centralizer and sample, guarantee upper and lower examination post (with the post deviation post before adhesive is cured to certain firmness of being excused from an examination) with one heart.
E., after adhesive solidifies, use cutter sweep to cut to ground along the contour of upper and lower examination post.
F. upper and lower examination post is connected with puller system respectively, carries out pull-out test, test rate is controlled with crosshead displacement speed, records breakdown strength (MPa) and collapse state;
G., after having tested, the glue adhered on upper and lower examination post, reject gently, clean out in order to using next time again with pocket knife.
The utility model not only can be checked the bonding degree of overlay film or coating and base plate, also can detect the ply adhesion between coating; The effect of investigating overlay film how, whether the matching of coating reasonable, evaluates the whole adhesion effect of overlay film or coating comprehensively.
The utility model has the advantages that:
1) overcome the human factor impact of pulling open in the test of method adhesion, alleviated experimenter's labour intensity, improved work efficiency;
2) will test puller system and be combined with the method for pulling open, realize at the uniform velocity drawing, improve accuracy, the reappearance of test data, for test result provides science more, objective and accurate foundation;
3) have simple in structure, easy to operate, with original test equipment can be compatible etc. characteristics, cost is cheap, practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
