Today, the dry ramming material manufacturer will tell you about the performance and composition of the ramming material. We all know that the composition of the quartz sand ramming material produced by the dry ramming material manufacturer is based on the actual production needs. Through the composition of refractory materials and powder materials of various materials, a small amount of auxiliary agent can be added in the production to improve the burning efficiency. What are the uses of the material combined with auxiliary agent in use? What are the advantages of the use performance?
The ramming materials produced by dry ramming manufacturers use aqueous solutions of magnesium chlorides and sulfates, as well as phosphates and their polymers as binders. They also often use organic compounds with high carbon content that form carbon bonds at high temperatures and temporary binders. Chrome ramming materials are commonly used as binders with mirabilite. High alumina and corundum ramming materials often use phosphate, chloride, sulfate and other inorganic compound of phosphoric acid and aluminum as binders. When phosphoric acid is selected as the binder, due to the reaction between phosphoric acid and Activated alumina in the ramming material during storage, the precipitation of water insoluble aluminum orthophosphate is generated, which leads to coagulation and hardening. To extend the storage life of ramming material, appropriate preservative must be added to prevent or delay the occurrence of coagulation and hardening. Generally, oxalic acid is selected as the preservative.
The performance of ramming materials produced by dry ramming manufacturers is usually mainly used in areas that come into direct contact with molten materials. It is required that refractory materials must have good volume stability, density, and corrosion resistance, so high-temperature fired or electric melted raw materials are generally selected. The maximum particle size and usage of ramming materials are related to the construction method. Most ramming materials have low room temperature strength before sintering, and some have low intermediate temperature strength. Good bonding can only be achieved after reaching sintering or carbonization of carbon containing compounds in the binder during heating.
The fire resistance performance of quartz sand ramming material produced by dry ramming material manufacturer shows that the performance is more stable, the use advantage is engraved, and the waste of production materials is greatly reduced and production consumption is saved through accurate material and auxiliary material ratio, and the ramming material has high stability and corrosion resistance under high temperature.
