Description

Technical Field

[0001] The utility model relates to the technical field of architectural coatings, and particularly relates to a device for detecting the dynamic anti-cracking performance of putty. Background Technique

[0002] Putty is a base material used for wall repair and leveling, laying a good foundation for the next decoration (painting or wallpapering). Putty is divided into two types: interior wall putty and exterior wall putty. Exterior wall putty has high colloidal property and strength to resist wind and sun exposure, but its environmental protection index is slightly lower. Interior wall putty has better comprehensive performance and is healthy and environmentally friendly. At the same time, it is necessary to detect putty during use. In the prior art, the prepared putty sample is placed on the workbench, pressed with a pressing plate and the nuts are tightened. After turning on the power switch, the rising switch is turned on, and the cutting edge slowly rises. During the slow rising process of the cutting edge, the blank area of the sample is observed. When cracks appear, the crack width is observed and recorded at any time until the putty layer cracks. When observing and reading, the cutting edge should not retreat to prevent the sample from retracting. After turning on the stop switch, the cutting edge no longer rises. After the observation is completed, the nuts and the pressing plate are loosened, and the sample is removed.

[0003] During the detection process of the existing detection equipment, it is necessary to measure the crack width with the help of external equipment, resulting in a relatively cumbersome overall detection process, and it is difficult to guarantee the measurement accuracy.

[0004] Therefore, it is very necessary to invent a device for detecting the dynamic anti-cracking performance of putty to solve the above problems. Content of the Utility Model
