Abstract
A scraper knife is prepared from 5-9 parts of silicon dioxide, 3-9 parts of n-decane, 3-7 parts of aluminum oxide, 1-3 parts of polyethylene, 4-10 parts of high-density polyethylene, 12-39 parts of iron powder, 0.2-0.9 part of polytetrafluoroethylene, 2-6 parts of sodium hydroxide, 20-23 parts of sodium nitrate, 3-9 parts of zinc oxide, 3-7 parts of tetraethoxysilane, 5-12 parts of high-alumina cement, 6-8 parts of coal ash, 3-12 parts of kaolin, 4-10 parts of sodium sulfate and 3-8 parts of kieselguhr. The formulation and batching are reasonable, the manufactured scraper knife is higher in density, higher in tenacity and not likely to crack or deform, and a smoother plane can be manufactured.
Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a spatula. Background technique [0002] The spatula is a common hand tool. Due to the grinding problem during the use of the spatula, various deformations and cracks will occur on the surface of the spatula, which will affect its service life and the flatness of the machined plane. Contents of the invention [0003] The purpose of the present invention is to provide a spatula, which is made of the material of this design, has good wear resistance and toughness, is not easy to deform and has a long life, and the plane produced is also flatter. [0004] A spatula is made of the following materials: 5-9 parts of silicon dioxide, 3-9 parts of normal silane, 3-7 parts of aluminum oxide, 1-3 parts of polyethylene, 4-10 parts of high-density polyethylene 12-29 parts of iron powder, 0.2-0.9 parts of polytetrafluoroethylene, 2-6 parts of sodium hydroxide, 20-23 parts of sodium nit...
