Apparatus and method for measuring surface adhesion of materials

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 a material, in particular to a device and a method for the adhesion degree of a coating surface. Background technique [0002] The contact between the same one or two materials is inevitable. Some materials need to be tightly bonded together, and some bonding together may cause unnecessary trouble. For example, furniture, electrical appliances, and decorative parts in the home are often made of leather, plastic, rubber and other materials. The decorative coatings used on walls or furniture are easy to contact 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. However, this adhesion phenomenon often exhibits different degrees of adhesion under different environmental humidity, temperature, and negative pressure. For long-term environment...
