The application relates to a mask adhesion test method. The test method comprises the following steps: placing a spacer on the surface of a substrate, so that the spacer covers part of the surface of the substrate. A test mask is prepared on part of the surface of the spacer, and the test mask extends to the exposed surface of the substrate. The test mask is completely separated from the substrate by applying force to the exposed part of the spacer, and the size of the force is tested. In the test method, a spacer is arranged between the substrate and the test mask, the spacer covers part of the surface of the substrate, and part of the surface of the spacer is exposed. The test mask is completely separated from the substrate by applying force to the exposed part of the spacer, and the size of the force is tested. In this way, the adhesion between the test mask and the substrate can be reflected by the size of the force, and the adhesion between the mask and the substrate can be tested.

This invention belongs to the technical field of five-axis machining centers, specifically an insulation device and method for a five-axis machining center cradle used in arc welding additive manufacturing. The device includes a turntable base, a worktable surface mounted on the upper surface of the turntable base, and an insulation mechanism mounted on the surface of the turntable base. This insulation mechanism directly insulates and separates the turntable base from the worktable surface. A maintenance mechanism is mounted at the lower end of the turntable base. The insulation device and method for this five-axis machining center cradle uses an insulation mechanism directly mounted on the turntable base and worktable surface. Insulation and heat insulation are achieved using an insulating pad within the insulation mechanism. A cleaning block with a mesh-like surface is installed on the exposed surface of the insulating pad, and air is blown into the cleaning block through a cleaning pipe to remove metal debris adhering to its surface. Simultaneously, the insulating pad is cooled by air, thus preventing any impact on the use of the insulation mechanism.

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.
