    Core tip: powder coating spray room production is the key process in the spray production process

    The key to the surface quality of spray workpiece lies in the control of various process parameters in the spray process

    The output of powder and atomized air are two key technical indexes

    Before formal powder spraying, try spraying several times

    At this time, the size of powder quantity and the uniformity of powder distribution can be observed at both ends of the spray room

    At this time, the powder moves in a straight line within 10cm-15cm from the end of the spray gun, and the external part is in the form of atomized powder

    The powder adsorbed on the surface of the workpiece is actually the powder with this atomization effect

    Is there any such powder Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint

    In fact, there is no ugly color in the wall paint, only the disharmonious color matching

    The use of wall color contains the knowledge of health

    Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health

    Grasp the basic principles of wall color and paint a colorful space

    1、 Wall paint color selection notice 1

    Light color is generally used for the top surface

    Light colors make people feel light, dark colors make people feel heavy

    Usually, the treatment of rooms is from top to bottom, from shallow to deep

    For example, the ceiling and walls of rooms are white and Paint House News: powder paint spraying room production is the key process in the spraying production process

    The key to the surface quality of spraying workpiece lies in the control of various process parameters in the spraying process

    The output of powder and atomized air are two key technical indexes

    Before formal powder spraying, try spraying several times

    At this time, the size of powder quantity and the uniformity of powder distribution can be observed at both ends of the spray room

    At this time, the powder moves in a straight line within 10cm-15cm from the end of the spray gun, and the external part is in the form of atomized powder

    The powder adsorbed on the surface of the workpiece is actually the powder with this atomization effect

    Whether there is such atomized powder is the standard to control the distance between the spray gun and the profile

    In addition to the process parameters, some necessary small links should also be noted

    1

    The position of the spray gun shall be inclined to the direction of the workpiece

    The spray gun shall be vertically parallel in arrangement, and the end part shall be kept in a straight line

    There shall be no overlap between the spray guns

    The position of the upper and lower spray guns shall be suitable to cover all the workpieces with powder

    2

    The function of fluidizing air pressure control fluidized bed is to make use of the role of air flow to form a proper fluidization state of powder

    The hand feel is similar to the state of liquid flow

    The detection of fluidization reaches the full state

    The simplest operation is: when the powder is stirred by hand or stick, there is no resistance

    Fluidization is convenient for powder suction pipe

    Under the action of accelerating wind, atomization effect will be produced

    Insufficient or excessive pressure will lead to insufficient fluidization

    3

    The powder adsorbed on the profile surface only accounts for about 1 / 3 of the powder output of all spray guns

    There are many powder scattered in the spray room

    The recovered powder must be mixed with the newly added powder according to the appropriate proportion, with good effect, so the powder should be recycled in time

    4

    The enclosed powder in the spray room is easy to be polluted by the external air suspension

    After spraying, the profile surface is easy to produce floccules or shrinkage holes, which will affect the flatness of the profile surface after baking

    Therefore, the spray room should take sealing measures to prevent the invasion of pollutants

    5

    The residual powder in the trachea shall be cleaned in time, which is not used for a long time, easy to agglomerate, and the powder is easy to spit out, which affects the spraying effect

    6

    The standby powder barrel can be used for powder change, which can effectively improve the labor efficiency

    The dust-proof and moisture-proof maintenance work of the standby powder barrel must be done well to ensure the quality of the remaining powder in the powder barrel

    7

    In addition, the work of powder supplement should also be paid attention

    Although the technical parameters have been debugged before the normal production, the work piece should be constantly monitored through the window of powder supplement, and the powder supplement should be carried out in time when it is found that the powder is shallow or not adsorbed

    Because the amount of powder ejected from the manual friction gun is larger than that from the automatic gun, the hand swinging speed of the manual friction gun can be appropriately accelerated
