Device and method for determining surface tenacity of material

Abstract

The invention relates to a device and a method for determining the surface tenacity of a material. The device comprises a test environment, a first sample fixing bed, a second sample fixing bed, a temperature controller, a humidity regulator, a pressurization controller and a pressurization regulator, wherein the first sample fixing bed is arranged in the test environment and used for fixing a first test workpiece; the second sample fixing bed is arranged in the test environment, used for fixing a second test workpiece and opposite to the first sample fixing bed; the temperature controller is coupled with the test environment and is a device for controlling the temperature setting of the test environment; the humidity regulator is coupled with the test environment and is a device for controlling the humidity setting of the test environment; the pressurization controller is arranged in the test environment, and the pressure output end of the pressurization controller is coupled with the first sample fixing bed; the pressurization regulator is coupled with the pressurization controller so as to regulate the output pressure of the pressurization controller. By separating tensile forces (namely, tenacity L) of two test samples, the tenacity between two adjacent materials can be judged.

Description

technical field [0001] The invention relates to a device and a method for measuring the adhesion degree of materials, in particular to a device and a method for measuring the adhesion degree of paint surfaces. Background technique [0002] The contact between the same or two materials is inevitable. Some materials need to be bonded together tightly, and some materials may cause unnecessary troubles if they are bonded together. For example, furniture, electrical appliances, and decorative parts in the home are often made of leather, plastic, rubber and other materials, and the decorative paint used on the wall or furniture is easy to come into contact with these objects. If adhesion occurs, when moving these objects, It will often cause damage to the coating film, and some will even peel off in pieces, affecting the appearance and use effect. And this adhesion phenomenon often shows different degrees of adhesion under different environmental humidity, temperature, and negati...
