Product description

High Quality Phosphate Fire Resistant Mud

The method of phosphate refractory mortar

Phosphate refractory slurry is the main raw material of high quality bauxite clinker or clay, which is used as a combination of solid phosphoric acid or liquid phosphoric acid.

Phosphate refractory mud is mainly used in the masonry of phosphate and high alumina brick, phosphate wear-resisting brick and blue crystal. Phosphate fire-resistant mud using solvent is the industrial phosphoric acid concentration was 85%, with warm water before use 1:1 dilution into 42.5% of dilute phosphoric acid, and then to 30% - 30% of the amount of phosphate fire-resistant mud, tuning into need consistency.

The preparation of phosphate refractory mortar must be 8-24h and mud in advance. Pour the powder into the acid container, add the dilute acid, and the special person is responsible, stirring constantly, make the phosphoric acid and refractory mud fully react, then remove the impurities, make it uniform, and finally become thin gelatinous .If the temperature is too low and the agitation is uneven, there will be a thick layer of precipitation in the cylinder, which will cause waste. When the ambient temperature is lower than 200C, it is best to warm it around to make the mud temperature up to 400C, or to use 65-900c hot water when dispensing refractory clay .Use of high strength fire clay or fire clay with adhesive, all can be used.

It is suggested that the solvent should not be fully 85% phosphoric acid when it is prepared, otherwise, it will not only cause waste, but also make a suitable paste, which can not be scratched when it is thick. When dilute soup, tile blew up, unable to wipe with a certain thickness, finally spread slurry can only use a spoon, refractory brick joints caused by small, viscosity is not enough, poor cohesive force, laying brick is seen in the process of the draw
