Waste-ceramic-based electric power insulator sintered brick and production technique thereof

Abstract

The invention discloses a waste-ceramic-based electric power insulator sintered brick which is prepared from the following raw materials in percentage by mass: 5-10% of cement, 10-20% of iron ore tailing slag, 10-60% of ceramic electric power insulator particle, 5-10% of ceramic electric power insulator powder, 1-3% of curing agent and the balance of water. The production technique comprises the following steps: material selection and proportioning, casting, vibrational compaction, sintering for dehydration, and cooling. The production technique can effectively classify and recover various waste ceramic insulators, and converts the waste ceramic insulators into main raw materials of building bricks, thereby greatly enhancing the recovery rate and recovery value of the waste ceramic insulators, effectively avoiding waste of resources, lowering the operating cost for electric power line construction, and overcoming the defects of low load-bearing capacity, loose structure, high tendency to damage, poor high-temperature resistance, poor heat-insulating property and poor electric insulation property in the traditional slag brick.

Description

technical field [0001] The invention relates to a sintered brick based on waste ceramic power insulators and a production process, belonging to the technical field of electric waste recycling. Background technique [0002] With the increasing scale of the power system, in the laying process of power supply lines, it is necessary to use a large number of various insulators to support or connect the lines. Because ceramic insulators have high hardness, strong corrosion resistance, stable insulation performance, and high temperature resistance It is widely used due to its characteristics of high reliability and mature production process, but also because of its high hardness and strong corrosion resistance, it is extremely difficult to recycle it. At present, damaged or replaced ceramic insulators are generally used It is treated as solid waste by direct burial and other methods. On the one hand, it causes serious waste of resources, and on the other hand, it also causes high o...

Problems solved by technology

[0002] With the increasing scale of the power system, in the laying process of power supply lines, it is necessary to use a large number of various insulators to support or connect the lines. Because ceramic insulators have high hardness, strong corrosion resistance, stable insulation performance, and high temperature resistance It is widely used due to its characteristics of high reliability and mature production process, but also because of its high hardness and strong corrosion resistance, it is extremely difficult to recycle it. At present, damaged or replaced ceramic insulators are generally used It is treated as solid waste by direct burial and other methods. On the one hand, it causes serious waste of resources, and on the other hand, it also causes high operating costs of the power line system. Brick raw materials have been strictly restricted. The red bricks used as building wall materials are gradually banned and replaced by slag bricks. However, slag bricks have small pressure bearing capacity, loose structure, easy to be damaged, high temperature resistance and heat insulation performance. The lack of poor quality has brought great hidden dangers to building safety. At the same time, the electrical insulation performance of slag bricks is relatively poor. When power line leakage occurs, contact accidents are prone to occur, especially for high-voltage equipment. Its use needs, so it is necessary to develop a new technology to organically combine the advantages of waste ceramic power insulators with building bricks. On the one hand, it can meet the needs of resource recycling and reduce the operating cost of power lines. On the other hand, it can greatly improve The purpose of building material properties
