Aluminum dihydrogen phosphate ALUMINUM PHOSPHATE MONOBASIC PRIM-ALUMINUM
The series is used in fire-resistant amorphous materials and phosphoric acid brick, the finfShed products shall be used in blast furnace and hot air furnace. open hearth furnace, ladle furnace, electric furnace. soaking furnace for nonferrous smelting furnace, heating furnace, shaft kiln. rotary kiln. glass furnace. coke oven, tunnel kiln car table and petroleum processing equipment.
Main characteristics: favorable thermal shock stabi’ity, abrasive resistance and strong high-temperature toughness. have good mechanical strength in low and high temperature. it is popular with majority of refractory making and use manufacturers after many years of use. This series of products mainly have six specifications namely PA. PB, PC. PD powder form and AP135, AP155 liquid form.
Powder aluminum dihydrogen phosphate is white powder, excellent chemical binders for amorphous refractory materials, reaching the standard of like products in Japan. We are the only manufacturer adopting vacuum electric heating for producing such products domestically, the products feature uniform and stable product quality, d’ifficult to agglomerate, long storing period etc.
