Silica ramming mass manufacturers show you how to store ramming mass

The Silica ramming mass manufacturer tells you that the refractory ramming mass is prepared from a high proportion of granular materials and a very low proportion of binders and other components, and even all of them are composed of granular and powdery materials, which need to be rammed strongly Bulk materials for construction in the same way.

Some ramming materials do not add binders but only add a small amount of co-solvent to promote their sintering. Sodium silicate, ethyl silicate and silica gel are commonly used as binders in acidic ramming materials. Silica ramming mass manufacturers tell you that alkaline ramming materials use magnesium chloride and sulfate aqueous solutions, phosphates and polymers as binders, and often use higher carbon content, which forms carbon-bonded organic matter and temporary at high temperatures. Sexual binders.
The manufacturer of Silica ramming mass tells you that phosphoric acid, aluminum phosphate, sulfate and other inorganic substances are often used as binders in high alumina and corundum ramming materials. When phosphoric acid is used as the binder, during storage, due to the reaction between phosphoric acid and activated alumina in the ramming material, water-insoluble aluminum orthophosphate precipitates and hardens, which loses plasticity and is difficult to construct. Therefore, it is necessary to extend the ramming material. For a longer storage period, it is necessary to add an appropriate preservative to prevent or delay the occurrence of coagulation and hardening, and oxalic acid is usually used as a preservative.
Silica ramming mass manufacturers tell you that carbonaceous ramming materials mainly use pitch tar or resin that can form carbon bonds as a binder. Carbon can prevent molten metal from wetting, improve erosion resistance and thermal shock resistance, and ramming in dolomite The material can also prevent the hydration of dolomite clinker.
