In Shotcrete Machine industry personnel are aware, mortar spraying machine is a various conditions of quality pumps, There are six mortar spraying machine “feature “: It features a wear resistance. In a certain extent, this spraying machine can withstand a variety of temperatures, pH and salt concentration of the solvent, at a temperature of 20-90 degrees in a variety of organic solvents then soaked for half an hour, both in appearance and physical properties, We have no change. Characteristics Second, friction. The mortar spraying machine friction coefficient of only 0.07-0.11. In the water-lubricated conditions, the dynamic friction coefficient is lower than PA66 and POM half. Three characteristics, impact resistance. Plastic part is made from ultra-high molecular weight polyethylene, and ultra high molecular weight polyethylene impact strength among the first general engineering plastics, can remain stable at minus 196 ℃, which no other plastic can not be achieved. Features four should face. In a variety of conditions ports, subway tunnels and the like, can be used in mortar spraying machine. Featured Five, no noise. Since ultra high molecular weight polyethylene is absorbent plastic, so very good silencer reduces the noise during transport. It features six security. This spraying machine safety is very high, the use of ultra high molecular weight polyethylene chemically very stable and non-toxic, non-polluting.
