At present, the application of refractory materials presents characteristics of characteristics, functionalization, diversification, refinement, high efficiency and low consumption, and the development of refractory materials must adapt to it. The application of sodium hexametaphosphate in refractory materials also meets the new needs of user industry, and the development direction of refractory materials, such as characteristics, integration, green, low consumption, so that the adaptability of refractory materials is the main factor of diversification.
Now, the emergence of various materials can still meet the needs of major industries. Glassy industrial sodium hetaphosphate dissolved slowly in water, so used as a refractory binder is to be pulverized into powder to accelerate its dissolution, it can be mixed with water in any proportion, so that refractory materials for its good fire resistance and become known as the material. Therefore, enterprise users still need to know the relevant standards when selecting materials:
1. Refractoriness of materials
2. Compressive strength of the material
Some enterprises choose refractory materials, not only consider the refractoriness, but also the refractoriness and heat resistance, the compressive strength of the data.
Sodium hexametaphosphate is a new refractory material with good properties in phosphate. Good thermal shock stability, high compressive strength, slag corrosion resistance and impact resistance, with high softening temperature under load and chemical stability. Its use temperature depends on the variety and grade of raw materials, between 1000~1800℃. As some use magnesium material as refractory aggregate and powder, more will use industrial sodium hexametaphosphate as binder.
In addition, it has a linear long chain configuration, which is adsorped to the surface of the particle by the end group, while the middle chain is basically not involved in bonding, which can provide additional electrostatic repulsion. At this stage, affected by the economic downturn, weak demand, binding force increases, the influence of such factors as resources and environmental protection high temperature industrial and refractory industry entered the new stage of development of the mass transfer efficiency, adaptability to refractory raw material also has put forward the new request, beyond the traditional sodium hexametaphosphate as binder can be used in the environment of high temperature is ranked just right, actual effect and progress.
