Water-packed water colorful paint has become the mainstream products of outer wall paint, and the construction problem has also become the focus of attention, how to improve efficiency on the basis of the water-packed water exterior wall effect to achieve the best is the concern of water-packed water construction personnel, the following finishing a few water-packed water spray gun use precautions, hope to help water-packed water construction personnel.
1, stable, suitable air pressure
1, the size of the air pressure to use the air pressure specified in the instruction manual, before the use of tools, to check the air pressure, absolutely not exceed the prescribed air pressure, otherwise the consequences can not be imagined.
2, gas sources must use dry and dust-free ordinary compressed air, strictly prohibit the use of oxygen and any flammable gases, so as not to cause accidental injury
.
3, each time the work is completed, be sure to separate the pressure pipe from the tool.
4, when multiple spray guns share a compressor, the capacity of the compressor must match, otherwise it will cause insufficient air pressure, affecting the spray effect.
2, operation of the general
1, before operation, especially after cleaning or repair work, you must check whether the screws are fastened, if loose, please tighten the screws. Tighten the nozzle kit parts.
(1) air connector in the lower part of the handle of the water-packed water multicolored paint spray gun. Blow the air hose clean before installing it.
(2) spray gun is treated with coated preservatives before it is left the factory, so rinse the spray gun thoroughly with a thinner before use.
(3) when using the spray gun, adjust the required spray pressure. Check the spray drawings on paper and, if necessary, change the pressure to re-adjust.
2, pressurized storage tank cover, equipped with a vent valve, add paint, first close the air inlet switch, and then pull up the vent valve ring, remove the pressure bucket remaining compressed air, the pressure meter indicates zero in order to open the reservoir filling.
In addition to pressurized storage tank cover there is also an inlet control valve, you can control the air pressure size by adjusting the air valve switch to control the speed of the material, according to the spray colorful paint pattern particle size to adjust the air inlet valve pressure, particle atmospheric pressure is small, particles small air pressure can be larger, generally sprayed multicolored when the air pressure of the storage tank control at 0.06 to 0.1mPa is good.
3, the position of the spray gun aligned
there are three knobs behind the gun: the first is to adjust the fan surface, that is, through it to adjust the size of the area of the material when spraying; Through it controls the gap between the gun top pin and the feeding port, so as to control how much material is produced, the closer the needle is to the nozzle, the smaller the flow, the smaller the particles that are sprayed, the lower the back, the greater the flow, the larger the particles sprayed out, the larger the general spray paint when the beginning to adjust Good after no need to adjust more; the bottom knob is to control air pressure, spraying, air pressure is too small, particles can not be fully expanded, spray not a larger pattern effect, air pressure is too large, particles are easy to be sprayed or hit the wall pattern is not round with a small tail phenomenon.
4, gun grip position
spray gun is controlled by the palm of the hand and fingers, the general palm, thumb, ring finger and small finger holding the spray gun, middle finger and index finger pull the trigger. In practice, many construction workers in a long period of work will occasionally change the position of holding a gun, only with the thumb or ring finger or small finger, middle finger and index finger pull the trigger. This spraying can greatly relieve fatigue and improve work efficiency.
