Description

Technical Field

[0001] The utility model relates to the field of mortar testing equipment, in particular to a device for detecting the leveling property of waterborne polyurethane mortar. Background Technique

[0002] Waterborne polyurethane mortar is a kind of mortar prepared by using waterborne polyurethane resin as the main binder and combining cement, sand quartz or other fillers. The leveling property of waterborne polyurethane mortar refers to the property that it can flow smoothly and self-level during the construction state, and is easy to spread and form a uniform and flat surface. Good leveling property is beneficial to ensure that the mortar can evenly fill the gaps, closely combine with the base layer, reduce the construction difficulty and improve the work efficiency. And the leveling property is also called fluidity. To ensure the quality of the production of waterborne polyurethane mortar, the factory will sample the waterborne polyurethane mortar in batches and detect its leveling property.

[0003] At present, the fluidity of waterborne polyurethane mortar is mostly used to evaluate the fluidity performance of waterborne polyurethane mortar. According to the literature regulations of "JCT985 Cement-based self-leveling mortar for floor", a hollow cylinder with an inner diameter of 30mm and a height of 50mm is placed in the center of the test plate. After the self-leveling mortar fills the cylinder, start timing. Lift it vertically upward by 5cm - 10cm within 2s and keep it for 10s - 15s to make the sample flow freely. After 4min, measure the diameters in two directions and take the average value as the mortar fluidity. In the test of this method, the staff needs to lift the cylinder and keep its height for a certain time, which increases the labor intensity of the staff to a certain extent.
