Water-packed sand, water-packed water colorful paint construction tools and construction matters

1. Air compressor: requires more than 8KG pressure supply and pressure tank is large, and requires uniform gas supply, can not be large or small.
2. Spray gun: choose the right suitable non-damaged spray gun according to the size of the construction area and the particle size of the sprayed main material.
Inding pressure
uniform material pressure is the primary condition of spraying the main material is generally controlled between 0.01 and 0.03, if the uniform with the gun speed and scatter evenly considered qualified (the actual construction can be properly debugged to their own feel the most appropriate color pressure standard) .
1. Too large: easy to accumulate and can not be sprayed evenly, will cause the flow hanging, can not achieve the effect of the spray to be sprayed.
2. Too small: will cause unexpected, small, so that can not be properly sprayed, will affect the spray effect and construction work.
air pressure
the air pressure of the spray gun is generally based on the pressure valve at the rear of the debug gun (the pressure valve at the bottom of the air inflect is also the end of the handle) (it is not recommended to add another pressure meter, if the pressure meter is not well debugged easy to cause Insufficient gas supply affects spraying), when the pressure control valve can be rotated clockwise to completely close, and then counterclockwise rotation of a lap and a half is the most suitable air pressure, of course, if the air pressure is not enough at this time, you can continue to a quarter of a turn of the way of commissioning.
1. Air pressure is too large easy to break the main material color point, the spray effect is more fuzzy and needle eye-like color point more, the color point surrounding the explosion state, the overall effect will be gray and dark, can not achieve the desired effect.
2. Too small a color point will accumulate flow hanging up to the desired spray color point size effect. The resulting effect bends and droops and appears to be in a state of weakness.
construction environment is
1. The substrate treatment must be flat, the primer should roll evenly, to ensure the uniformity of the color, otherwise it will affect the hair flower of the main material, can not make the overall color to achieve consistency (fire primer spray method can refer to the required bone construction method for spraying).
2. Outdoor construction must be selected in clear and dry weather construction, air humidity is large, will affect the drying speed of lacquer and the main material will flow and affect the construction effect. If construction is really necessary, it can be improved by using the method of less spray and more channels.
National spray gun
to play small spray gun for example, the barrel is mainly used to fill the main material, air inflect hole is located at the bottom of the handle, the air pressure valve has been said in front of the control flow valve is located at the upper end of the handle, the end of the gun needle is thicker that is, mainly used to control the number of materials, generally control the material to adjust to a suitable position, too small will tear the color point, too large Spray gun will have no force channel, generally adjusted to reveal two to three turns of silk buckle is appropriate, such as when the larger color point can be appropriately adjusted large (generally exposed silk buckle is large, and the other is small), spray wide narrow valve, located at the upper end of the control of the drain valve that smaller is, according to the construction area can be appropriately adjusted the width of the material, clockwise narrow, counterclockwise wide.
of course, too narrow also easy to cause color point accumulation and tearing color points, too wide spewing out of the color point will be scattered will also affect the strength of the material, so can only be properly debugged. The nozzle is the small mouth of the main material when spraying. Pressure handle, located in front of the handle, in the spray to play the role of controlling the material (acting in the form of the pistol trigger), the general spray pressure to press to the end, pressure to the end, not allowed to half-pressure state, half-pressure state will tear up the color point, resulting in insufficient color point. The pressure cap is generally connected to the trachea, and when used, the buckle hopper rotates until it does not leak.
