Product detais
Phosphate wear-resistant plastic is made up of a combination of powdered and powdered materials and a plasticizer such as plastic clay. It is added with a small amount of water and thoroughly mixed. It is a paste and remains for a long time. A highly malleable amorphous refractory.
Granular and powdered materials are the main components of plastics, generally accounting for 70% to 85% of the total. It can be composed of refractory raw materials of various materials, and the plastics are often classified and named according to the materials. Since such amorphous refractories are mainly used in various heating furnaces which are not in direct contact with the melt, clay clinker and high alumina clinker are generally used. Lightweight plastics can be used as light-weight materials.
Plasticity clay is the main component of plastics, although it accounts for 10% to 25% of the total amount of plastics, but it has a great influence on the plasticity of plastics, the bonding strength, volume stability and fire resistance of plastics and hardened bodies. Big. In a sense, the nature and amount of clay can be considered to control the properties of the plastic.
Generally, plastics should have high plasticity, and after long-term storage, they still have certain plasticity, which is called plastic work.
Plasticity is related to the clay properties and the amount of clay used. In addition, it depends mainly on the amount of water, which increases with the amount of water. However, too much water will have an adverse effect. Generally 5% to 10% is suitable. In order to make plasticity plasticity not significantly reduced during its storage period, hydraulic binders cannot be used. Plastics can be constructed without special techniques. When used to make a lining, the plastic can be taken out from the sealed container, laid between the hanging bricks or the hooks, and tamped with a wooden hammer or an air hammer (each layer is 50 mm to 70 mm thick). Surface processing can be performed before it has been hardened. In order to facilitate the discharge of water therein, the vent holes are made at regular intervals. Finally, according to the design, the expansion and contraction seam is set. If it is used to make a whole furnace cover, it can be applied on the bottom mold first, and then hoisted after drying. The plastic bottom can vary depending on the quality of the granulated and powdery base used. For example, ordinary clay can be used for 1300 ° C ~ 1400 ° C, high quality 1400 ° C ~ 1500 ° C; high aluminum 1600 ° C ~ 1700 ° C or even higher; chrome 1500 ° C ~ 1600 ° C.
