Wear-resistant Refractory Plastic with High-strength and High-temperature Glue
Wear-resistant refractory plastic is composed of refractory aggregates, powders, binders, and plasticizers. Among them, refractory aggregates are divided into clay clinker, high alumina clinker, corundum aggregate, etc. according to their materials. Binders include clay bonding, water glass bonding, phosphoric acid or aluminum phosphate bonding, aluminum sulfate bonding, etc. It is configured by selecting raw materials of corresponding materials according to the working environment and usage parts of the kiln.
RS Wear-resistant Refractory Plastic Containing High-Temperature Glue
There are also a variety of wear-resistant, fire-resistant, and plastic materials. For example, silica, clay, high alumina, corundum, zircon, carbon or silicon carbide, magnesia and magnesium chromium, etc.
Features of Wear-resistant Plastic Refractory Material
① It has a certain plasticity and is easy to construct.
②High bonding strength at medium and high temperatures.
③Good wear resistance and peeling resistance.
④ Compared with other amorphous refractory materials of the same material, it has good thermal shock stability.
Wear-resistant refractory plastics are mainly used in various heating furnaces that are not in direct contact with the melt. Such as the burner of the heating furnace, the discharge port of the cement rotary kiln, and the feeding port of the vertical kiln. High-temperature cyclone separator lining, roof and furnace wall lining of steel rolling heating furnace. It can also be used as the lining of various heat treatment furnaces.
Wear-resistant Refractory Plastic Construction Requirements
(1) Before construction, ensure that the laying area is clean. If it is repaired with fire-resistant plastic, it should be properly glued.
(2) The vibration of the material should be uniform. If the depth of the construction site is large, it should be filled or filled in layers from bottom to top. After each layer is completed, it should be vibrated and compacted to ensure that there are no voids inside. Serious over-temperature phenomena often occur in the cavity during operation. After the material is initially solidified, use a small hammer or hard object to conduct a comprehensive knocking inspection. If the sound is dull, it indicates that it is dense and qualified. If the sound is loud and delayed, there is a hole inside.
(3) If the construction area is small, it should be repaired manually. Before repairing, carefully check whether welding of grab nails is required. If the repair area is large, it should be filled with pouring materials. After construction, the surface should be smooth and smooth, and the size should comply with the drawing requirements.
