In January 24tons refractory high alumina castable cement are packed for delivering to customer in Bangladesh. High quality and best price refractory material products in Topower Refractory.
1. How to use refractory high alumina castable cement?
Refractory cement can harden after being mixed with water. Normally, there is no need to add other binders. You can add some refractory aggregates and powders. If you only use refractory cement , cracks may appear after high temperatures. It can be used for cementing and refractory aggregates. It can be made into refractory mortar or concrete, and can also be used as lining in various industrial furnaces.
2. Refractory cement and refractory soil cannot be used together, otherwise it will reduce its use value.
2. What are the characteristics of high alumina castable cement ?
1. It is usually used as a binding agent in thermal kilns or wall linings. Unlike other types of cement, it can still maintain a strong bonding effect at high temperatures.
2. The strength of refractory mud at room temperature can ensure the normal shape of the prefabricated parts after hardening, and it can also use the principle of cement solidification to quickly separate the moisture from the cement fasteners, thereby making the internal structure tighter.
3. What are the precautions for using high alumina castable cement?
1. When the temperature is 350 degrees, it is easy to cause local bursting. At this time, you must bake carefully. If there is still a lot of steam coming out after keeping warm, you must slow down the heating rate.
2. When ventilation is not smooth and water vapor cannot be discharged, the insulation time should be extended according to the actual situation.
3. When baking with heavy oil, avoid spraying the heavy oil on the surface of the furnace lining, so as to avoid local bursting problems.
4. Precautions when preparing refractory high alumina castable cement for construction
1. Stir evenly: When mixing refractory cement, it is necessary to ensure that water and mortar are fully mixed to avoid loose cement or weak bonding during the construction process.
2. Construction environment: The construction of refractory cement needs to be carried out in a dry, windless and rain-free environment to prevent the mortar from being affected by adverse weather and causing problems.
3. Construction surface preparation: Before construction, the surface needs to be fully cleaned to ensure that the surface is dry, free of oil and debris, so as not to affect the adhesion of the refractory cement castable .
4. Construction tools: Professional construction tools, such as refractory cement trowels, hammers, pliers, etc., are required to ensure the construction effect.
5. Construction technology: The construction of refractory mortar requires mastering certain construction techniques, such as the thickness of the mortar, the direction of the mortar, and the density, etc., to ensure that the construction effect meets the requirements.
6. Construction quality inspection: After the construction is completed, the construction quality needs to be inspected, such as the density, bonding strength, thickness and other indicators of the mortar, to ensure that the construction quality meets the requirements.
