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.
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.
