Abstract: Random Copolymer Polypropylene (PP-R) pipe is a new type of chemical building material developed internationally in the 1990s. Compared with steel pipe, copper pipe and composite pipe, PP-R pipe has many irreplaceable advantages and its market share is at Far away from the leading position.This paper discusses its characteristics and applications in the construction of water supply engineering. Key words: random copolymer polypropylene hot melt connection nominal diameter
Grinder is an important part in the whole grinding system. Its specialty is not that obvious, but it is the direct contact to the workpiece. Our Force Control System, Active Contact Flange, or Constant Force Actuator is intalled in the middle of robot hand and grinder, which can control the force magnitude flexibly. It can optimize the grinding effect and improve the grinding efficiency a lot.
