Refractory insulation material

Refractory plastic is made of a certain degree of refractory aggregate, powder, binder, admixture, add water or other liquid with full mixing. The refractory aggregate is divided into: clay, high-alumina, corundum, siliceous, magnesia, chrome, zircon stone and silicon carbide refractory plastic. As per type of binder is divided into: water glass, phosphate, sulfate and organic binder refractory plastic and so on. As per the hardening method is divided into: gas hard or hardened fire plastic.
Introduction: Refractory plastic has excellent wear resistance, superior adhesion and high operating temperature (not less than 1600 ℃), the construction process is simple, short duration, after the completion of the construction no need to bake oven. Its life span is significantly higher than other ordinary wear-resistant refractories, widely used in electric power, metallurgy, steel, ceramics, petrochemical and other industries.

Product introduction

Refractory plastic is made of a certain degree of refractory aggregate, powder, binder, admixture, add water or other liquid with full mixing. The refractory aggregate is divided into: clay, high-alumina, corundum, siliceous, magnesia, chrome, zircon stone and silicon carbide refractory plastic. As per type of binder is divided into: water glass, phosphate, sulfate and organic binder refractory plastic and so on. As per the hardening method is divided into: gas hard or hardened fire plastic.

Refractory plastic has excellent wear resistance, superior adhesion and high operating temperature (not less than 1600 ℃), the construction process is simple, short duration, after the completion of the construction no need to bake oven. Its life span is significantly higher than other ordinary wear-resistant refractories, widely used in electric power, metallurgy, steel, ceramics, petrochemical and other industries.

Performance advantage

During usage,refractory plastic have good plasticity. Plasticity is easy to deformation of the mud after the failure of the performance, generally showed by plastic index. Refractory plastic plastic index is generally 15% to 40%, the actual can be 20% to 35%, less than 20% when the mud dry and hard with difficult construction; if more than 35% it is too soft with large shrinkage after burning. Refractory plastic with appropriate plastic index can be kneaded into a group by hand, no water secretion, no sticky hands.

Refractory plastic usually chooses clay clinker with good sintered material, high-alumina clinker, fused corundum, etc. for aggregate. Bound clay is an important raw material of plastic, which have a direct impact on plastic properties, in addition to its good plasticity and good adhesion, but also should pay attention to the clay sintering performance and alkali content indicators. Plastic can be mixed with a certain amount of clay, with its masonry furnace drying will produce shrinkage, heating and cooling will be further contraction, if the shrinkage is too large, it will cause the furnace body damage. Add the right amount of alumina and other fine powder by alternative or part of the alternative clay, you can reduce the drying shrinkage and high temperature heating shrinkage, but also improve high temperature performance. At the same time add the right amount of swelling material to the plastic, such as kyanite fine powder, the use of kyanite mullite petrochemical effect of the volume expansion offset plastic matrix high temperature shrinkage.
