In the industrial equipment of thermal insulation section, refractories often bear the damage of high temperature and various physical and organic chemical characteristics. Most provisions for refractory materials are as follows:

1. Heat resistant;

2. Be able to withstand a series of organic chemical processing processes in the working room.

In order to accurately measure the technical parameters of refractories, a series of performance parameters are clearly put forward: fire rating of refractories, compressive strength of high-temperature structure, relevant cost of high-temperature volume, heat resistance and slag resistance, etc. The performance parameters of this kind of work are generally the key factors to consider the quality of refractory materials and its possible application standards.

Some working characteristics of corrosion-resistant materials are generally the efficacy of some service performance and physical index values. Therefore, the service performance and physical performance parameters of refractories can also be used as the basis for identifying the technical parameters of refractories. For example, the heat resistance of fire safety products is related to the tensile strength, thermal expansion coefficient, plasticity, modulus and thermal conductivity of refractories, while the porosity and strength of fire safety products can cause great damage to the corrosion of fly ash. Therefore, in addition to accurately measuring the working characteristics of refractory materials, it is also of key practical significance to accurately measure some service properties and physical index values.

In addition, in order to better ensure the gap of insulating bricks, fire safety products should have appropriate appearance and accurate model specifications as far as possible.

The key factors that damage the characteristics of fire safety include:

1. Mineral composition;

2. It is the manufacturing standard of the whole process.

Therefore, in order to produce high-quality refractories, the quality of raw materials should be strictly controlled as much as possible, and the processing technology and manufacturing standards should be effectively selected. It is difficult to make superior goods without high-quality raw materials; Without high-quality raw materials, it is difficult to make goods with superior characteristics; Without high-quality raw materials, it is difficult to make goods with excellent characteristics and goods consistent with production and manufacturing standards.
