Tool set for putty scraping and coating small-size sample plate

Abstract

The invention discloses a tool set for a putty scraping and coating small-size sample plate. The tool set comprises a profile frame, a support plate, a base and a thickness-limitation sheet, wherein the appearance structure of the profile frame is a cuboid with a hollow structure, the wall thicknesses of surrounding side surfaces of the hollow structure are 20 millimeters, grooves are respectively formed in axial lines of the surrounding side surfaces and are provided with downward openings, the support plate is a cuboid provided with two hollow structures, a longitudinal round rod and a transverse round rod are respectively arranged below the axial lines of the surrounding side surfaces of the cuboid and are provided with threads of matched nuts, the base is provided with a two-step protruding structure block, the appearance structure of the thickness-limitation sheet is in a cuboid sheet shape, and the material of the tool set is a hard wear-resistant material in stainless steel, synthesis metal and acrylic plastic. By the tool set, the efficiency of the putty scraping and coating small-size sample plate in laboratory is improved, and meanwhile, the finished product fabrication quality of the putty scraping and coating small-size sample plate is ensured.

Description

technical field [0001] The invention relates to a complete set of tools for scraping putty small samples, which belongs to the field of preparation of putty performance test samples in laboratories. Background technique [0002] Putty is mainly made of synthetic resin emulsion, polymer powder, cement, inorganic gelling material, etc. as the main adhesive, together with fillers, additives, etc., and is used for indoor leveling or the bottom layer of exterior wall paint. Putty is generally a powdery material, which needs to be mixed with water to form a thick paste-like material commonly used in construction projects. During the application of putty in construction engineering, its performance needs to be tested in the laboratory. To test the performance of putty in the laboratory, it is first necessary to scrape putty on the substrate that meets the requirements of the standard, and make a small sample for use. [0003] According to the recommended standards of the construc...

Problems solved by technology

[0010] According to JG / T 157-2009 "Putty for Building Exterior Walls" and JG / T298-2010 "Putty for Building Interiors", the thickness requirement for the model base material, that is, asbestos-free fiber cement slab, is 4mm~6mm, not a definite Value, the tool used for the traditional scraping putty small sample is a single-piece frame tool. In order to avoid the thickness change of the non-asbestos fiber cement plate substrate affecting the thickness of the scraping putty on the substrate, the thickness of the frame is designed to be 1mm Or 2mm, the length and width of the hollow part of the mold frame are designed to be 1mm to 2mm smaller than the length and width of the base material. Putty samples are scraped on the upper surface of the substrate in the hollow part. In actual use, the relative position of the frame and the substrate is unstable, and the frame is easy to shake on the upper surface of the substrate, thereby affecting the putty scraping. The coating effect directly affects the efficiency of scraping putty small samples
