PURPOSE:To make temperature control easy, by providing heating parts for separately heating respective liquids on the way of liquid feeding pipings and between a feeding part used for feeding the liquids to be mixed and a mixing part of the liquids. CONSTITUTION:A main agent and a curing agent are respectively fed to a nondriven static type mixer 7 and are mixed together after respectively passing through accumulators 20, 21, a pressure controlling valve 6, a heater 5, respective connecting ports 42, 43, individual hoses 18, 19, check valves 14, 15 for preventing a reverse flow, and throttle valves 12, 13 for controlling respective flow rates and stabilizing the pressures of the liquids, in sequence. Then the mixed liquid is supplied to a discharging device such as a spray gun 9 or a head of electrostatic coater. A heater 5 has a spiral sheathed heater 90 in its central part; a pair of independent heat exhanging pipes 91, 92 are wound around the heater 90 and arranged by shifting them in the axial direction of the heater 90 and are respectively connected to the pipings of the main agent and the curing agent by inserting them into respective pipes. |
