Customer in Zimbabwe ordered 35 tons refractory cement
In Oct. 35 tons refractory cement are packed for delivering to customer in Zimbabwe.
The refractory cement is a seam that connects the refractory fire brick. Some indicators cannot be directly reflected immediately, but the adhesion of the actual use on the scene is the primary problem to pay attention to in the masonry.
Topower refractory as a Casting Refractory Cement Factory ask you to pay more attention to the on -site application of fire -resistant mud. The viscosity of fireproofed on the construction site is directly reflected. The adhesion is insufficient and the construction cannot be carried out. Therefore, when you are masonry, you must not be able to add too much water. The water slurry is separated and cannot be constructed.
The refractory cement should be buffered at high temperature in some requirement of Casting Refractory Cement Factory. If it is the case when the temperature exceeds 35 ° C or more, it should not be noted that the amount of water should not be too much should be noticed. And to observe whether it is condensed too fast, the one is too fast, after wiping the mud with the refractory brick and the brick, it is too late to put another brick on the refractory mud. Therefore, when the temperature exceeds 35 ° C, the refractory mud is condensed too fast, and the binding agent should be added appropriately.
If it is under construction in winter, when the temperature is lower than 5 ° C, the refractory mud will not have enough stickiness and cannot be constructed,which often happen Casting Refractory Cement Factory. In this case, pay attention to adding CMC or other adhesives, or find a way to improve it. Temperature at the construction site. Make the construction normally.
In actual application, the fire -resistant mud must not only bond the refractory brick bonding into the overall lining body, but also the working environment of the fire mud to resist as the refractory brick is the same. It must also withstand high temperature, airflow scouring, erosion and other erosion. Therefore, the quality of fire tolert should be paid to the same as the refractory brick in the masonry.
Under the action of high temperature stress, the thickness of the refractory mud seam cannot exceed 2mm, and the high temperature will also soften and deform by 2%. As Casting Refractory Cement Factory knows, the words are very small, and the impact on the masonry is not great.
The existence of fire -resistant mud keeps the lining structure of the furnace not only maintains quite intensity at high temperatures, but also has suitable elasticity, so that the entire lining is not destroyed by thermal stress, so the high temperature strain and elasticity of the firepid tolerant must be valued. This is why many manufacturers use refractory mud with phosphate.
Of course, the quality of fire -resistant mud is determined by the quality of raw materials in Casting Refractory Cement Factory. The adhesion and bonding time are the performance requirements of the reflection of fire mud. Too short bonding time cannot guarantee the plump mortar and the thickness of the brick. Extending, refractory mud is the main purpose of use, the most important thing to pay attention to is stickiness.
