The silo protection design is part of the silo structural design. Production practice has proved that due to improper protection design, it will affect the use of storage bins and even destroy the structure. It can be seen from the analysis of the cost of the warehouse that the steel used by the warehouse for the protection of the warehouse wall is quite large, and some are even more expensive than the structure itself. Therefore, we must pay attention to the design of the storage structure protection.
The physical and chemical effects of materials on the silo wall are various, and the common impact and wear of materials. In order to save steel as much as possible, in this protective lining design, as long as possible in production, "emery (building abrasive)" should be used as the lining material for the protection of the warehouse wall.
There are many factors for the protection level of the storage silo. In the specific design, the wear-resistant layer of the inner wall must be used in combination with the actual situation of the specific storage silo.
Coal industry selection (washing) of coal mine infrastructure projects: loading coal bunker, bottom coal bunker, raw coal bunker, buffer bunker, lump coal bunker, loading and unloading bunker at consolidating station, leak gate, chute, etc.
Infrastructure projects of building materials industry cement plant: clinker silo, raw meal silo, homogenization silo wear-resistant layer on inner wall and gypsum board factory wear-resistant layer.
Coal transportation system in power industry: wear-resistant layer on the inner wall of silo and funnel.
Chemical industry coking plant, calcium carbide plant, chlorine plant and various chemical engineering materials warehouse infrastructure projects: silo, hopper, batching wear tank inner wall wear layer.
Infrastructure projects of hydropower stations: spillway tunnels, diversion tunnels, and concrete slope wear-resistant layers.
Transportation and navigation basic projects: high-strength concrete wear-resistant layers such as ports, docks, bridge roads, and airport runways.
Sand blasting of steel structure-anti-corrosion and rust removing abrasive
Main purpose: the technical requirements of the blasting and blasting purpose of the workpiece material, the decontamination, welding slag and matt effect of the stainless steel blasting surface, the blasting and rust removal, decontamination and scale removal of the iron workpiece, increasing the coating and coating Focusing, aluminum workpieces are sandblasted and descaled for surface strengthening and finishing, copper workpieces are descaled and matte.
Brown corundum is made of bauxite and coke (anthracite) as the main raw materials and is smelted in high temperature in an electric furnace. The main chemical composition is AL2O3. TIO2 also contains a small amount of SiO2 and Fe2O3. The microhardness is HVl800-2200. The toughness is higher than SiC. The abrasive tool made of it is suitable for grinding metals with high tensile strength. It is also used for grinding glass products, industrial rust removal and water cutting.
(1) It can improve the smoothness of silicon wafers, optical lenses, precision instruments, polished glass shells, glassware, ceramic stones, leather, plastics and metal parts.
(2) Sandblasting cutting is an essential raw material for manufacturing grinding wheels, oil stones, emery cloth, and sand.
(3) It can be used as a good wear-resistant material for the construction of highway pavement, airport runway, wear-resistant rubber, industrial floor, anti-skid paint and so on.
(4) Can be used as chemical and water treatment filter medium and drilling mud weighting agent.
(5) It has a good effect on the protection of electroplating and nuclear pollution.
