Plastic Refractory Material, with strong plasticity. It is usually constructed by tamping method and formed into a ceramic structure after strong beating and high temperature baking. The medium temperature and high temperature structure have high strength, strong wear resistance and excellent thermal shock resistance. The Plastic Refractory Material are commonly used in the form of aluminum silicate refractory plastics, such as clay refractory plastics, high alumina refractory plastics and corundum refractory plastics, depending on the materials used. Different binders are used, and their performance and use are not the same.
Plastic Refractory Composition
The composition of Plastic Refractory Material is similar to that of refractory castables. It is made up of refractory aggregates and powders of different particles as raw materials, and is added with materials such as binder, plasticizer, preservative and anti-shrinkage agent. There are three main types depending on the combination of bonding methods: clay binder plastic, phosphoric acid combined plastic and aluminum phosphate combined with plastic.
Plastic Refractory Materials
(1) Clay Combined Plastic Refractory, which is composed of clay clinker, high aluminum clinker as the main material, and plastic clay as the binder. The mixture is mixed with water to form a mud material, and then pressed to form a brick having a certain plasticity. The main feature of this Plastic Refractory Material is that it has good thermal shock resistance and thermal peeling resistance. Mainly used for the top and furnace walls of rolling steel heating furnaces.
(2) Phosphoric Acid Combined Plastic Refractory, which is composed of clay clinker (or high alumina bauxite clinker) and corundum. Phosphoric acid or acidic aluminum phosphate is a binder, and a mixture of a plastic refractory clay, a preservative, and an admixture is added. The characteristics of the Plastic Refractory Material: high-temperature bonding agent has high strength, wear resistance and thermal shock resistance.
Made with a clay solution of 1.25 g/m3 density, made of clay clinker and high alumina clinker. Phosphoric acid combined with plastic, is a high-temperature wear-resistant plastic prepared by using aluminum phosphate solution as binder, corundum as aggregate, Al2O3 fine powder and fine powder as powder.
Aluminum phosphate or phosphoric acid combines with plastics and is used in industrial furnaces such as metallurgy, petrochemical, power and machinery industries. Mainly used for heat shock, erosion resistance, wear resistant lining. Such as the burner of the heating furnace, the discharge port of the cement rotary kiln, the shaft kiln feeding port, the high temperature cyclone separator and the like.
(3) Aluminum Sulfate Combined Plastic Refractory, which is composed of clay clinker or high alumina bauxite clinker and corundum as the main material, and aluminum phosphate solution as the binder. A mixture of a plastic refractory clay, a preservative, and an admixture material is added. The characteristics of the Plastic Refractory Material: high-temperature bonding agent has high strength, wear resistance and thermal shock resistance. The production cost is low and the use is wide.
Plastic Refractory Application
Aluminum sulphate is combined with plastic, which is mainly used for industrial furnace lining with high structural strength. For example, Plastic Refractory Material can be used as a ring furnace bottom prefabricated block, a forged furnace lining, a shaft kiln lining, and the like.
Plastic Refractory for Boiler
Refractory plastic is a refractory material that cannot be combined with water. Mainly used in circulating fluidized bed boilers. Due to shortcomings such as short storage time and poor fire resistance, it limits its application range. However, Plastic Refractory Material has some irreplaceable advantages. For example, plastic refractory construction furnaces have high temperature strength, excellent thermal shock resistance, low thermal conductivity, and flexible construction methods.
Plastic Refractory Installation
The Plastic Refractory Material has the ideal plasticity, good bonding performance and high strength after drying. After high temperature burning, it can be firmly combined with the previous liner. Can be used to repair nozzles, furnace walls, furnace doors and other parts of the furnace. It can also be directly used according to the use of the site, using the mixed materials or on-site mixing. Flexible and easy to use. This plastic refractory can be stored for more than 2 months and can meet the requirements of use at any time.
