Potash water glass firming agent

Potash water glass firming agent Acid-resistant glass cement is composed of water glass, curing agent and powder filler. Water glass, also known as sodium silicate chemically, is a type of metasilicate water solution. It will be known as Potash Water Glass if potassium metasilicate is used commonly. Sodium silicate cement has good mechanical strength, excellent acid resistance (except for fluohydric acid and pyrophosphoric acid) and cheap price, but high in factor of porosity and irresistible to alkali. Potash water glass cement is made up of potash water glass, condensed aluminum phosphate as curing agent and acid-resistant fillings. It is superior to sodium silicate cement in impermeability, resistance to dilute acid and cohesive strength.Potash water glass firming agent chemical examination report:ProjectGuaranteed ValuesExamination resultColorWhiteWhite powderThe PH value2-43Residue on sieve( 45um) ≤0.50.4Moisture %≤1.51P2O5 %65-7574.5Al2O3 %20-3022result Qualified
