Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a multifunctional scraper for testing water retention rate using vacuum filtration method. Background Technology

[0002] When using the vacuum filtration method to test the water retention rate of plastering mortar additives (JC / T 2380-2016) or plastering plaster (GB / T 28627-2023), a T-shaped scraper should be used to evenly spread the plastering mortar additives or plastering plaster on the mold to ensure that the sample surface is flat and the thickness is consistent, thereby ensuring the accuracy and repeatability of the test results.

[0003] However, different materials currently require different scrapers. For example, the scrapers used for plastering mortar additives and plastering plaster have similar structures, only differing in height. This not only increases production costs but also increases the difficulty of management and maintenance. Utility Model Content
