Abstract: Provided is an operation method for a coating exhaust treatment system that includes a filter configured to filter discharged air discharged from a coating chamber in which a coating object is spray-coated and collect overspray coating material included in the discharged air, and a powder dispersal means configured to disperse powder for forming a filter covering layer in the discharged air and form a filter covering layer made of a layer of the accumulated powder on a surface on the filter as the discharged air passes through the filter, the method including, when the number of repetitions of a first operation reaches a set number while the first operation and a second operation are being repeatedly carried out alternatingly, discarding coating material-containing powder and supplying fresh powder to a first supply tank, and when the number of repetitions of the second operation reaches the set number, discarding the coating material-containing powder and supplying the fresh powder to the second supply tank.

Abstract: After completion of a preceding painting in a preceding painting area, by an action of a preceding painting robot, a painting object (object to be painted) is caused to be held together with a holder by a transfer section near two painting areas. In succession, with maintaining connection between the painting object and the holder, connection between an arm leading end portion of the preceding painting robot and the holder is released. Thereafter, by an action of a subsequent painting robot, an arm leading end portion of the subsequent painting robot with keeping its connection to the painting object is connected to the holder held to the transfer section. With this, in the course of transfer of the painting object between the painting robots for displacing the painting object relative to a spraying means, a relative positional relation between the arm leading portions of the painting robots and the painting object can be maintained same.

Abstract: By setting a robot installing area at a higher pressure than an adjacent painting area, there is formed an air flow which flows from the robot installing area into the painting area. With this, in a painting facility in which a painting object is painted by paint spraying from a sprayer while displacing the painting object held to an arm leading end portion of a painting robot relative to the sprayer by an action of the painting robot, adhesion of paint to the painting robot and to a painting area lateral wall is prevented.

Abstract: A framing member forming a frame of a factory building is provided with a slit for attaching a holder on one side face of the framing member, the slit extending in a longitudinal direction of the framing member, the slit is provided with a detachment prevention mechanism configured to exert an action of preventing an insertion piece of the holder from being detached and to fix the holder to the framing member, along with an insertion of the insertion piece into the slit, and the holder is provided with a pinching piece configured to pinch an end edge portion of a wall panel between the pinching piece and the framing member to fix the wall panel to the framing member, along with the insertion of the insertion piece into the slit.

Abstract: In a first coating step, low electrical conductivity is imparted to a coating surface 21 of a non-electrically conductive coating object 20 and a first paint film is formed by applying a charged first paint to the coating surface 21 with free ions being suppressed. In a second coating step, a second paint film is formed by applying a negatively-charged second paint to a surface of the first paint film with free ions being suppressed, before the first paint film dries.

Abstract: Powder is sprayed uniformly and favorably from a powder nozzle into processing target air. In a coating mist collection apparatus, coating mist in processing target gas is collected by filters in a state in which a coating mist trapping filter covering layer made up of an accumulated layer of powder is formed on the surface of the filters. The coating mist collection apparatus is provided with a powder dispersion means that obtains a uniform powder concentration in the air in sealed powder tanks by dispersing the powder stored in the tanks in a uniform floating dispersed state, and is provided with a spray air conveying means that supplies the powder in the floating dispersed state in the powder tanks along with carrier air to powder nozzles through powder supply passages.

Abstract: It is determined that indoor condensation of hydrogen peroxide vapor is to occur, if there is a solution with which both (Equation 1): PT·y1=P01·x1·?1 and (Equation 2): PT·y2=P02·x2·?2 hold. With this, it is possible to accurately determine whether indoor condensation of hydrogen peroxide vapor is to occur or not in decontamination.

Abstract: Distribution of a precoat agent is made uniform in a target gas directing to a filter. To this end, an intake opening of a filter device is formed as a slit-like or rectangular opening extending in a width direction. An accumulation recess is formed in an upper edge portion of the intake opening to have a profile that opens downward as viewed from a longitudinal direction of the intake opening. The accumulation recess is continuously formed in the longitudinal direction of the intake opening. A precoat agent nozzle is provided in a longitudinal predetermined position of the intake opening for ejecting the precoat agent and carrier gas toward an inner depth surface of the accumulation recess.
