Please water-in-water colorful coating construction method
A. Tools:
1. Air compressor: required to reach more than 8KG of pressure supply and storage tank is larger, and the requirement of gas supply uniformity, can not be large or small.
2. Spray gun: according to the size of the construction area and the size of the main material sprayed particle size to choose a suitable good non-damaging spray gun.
Second, the material pressure: uniform material pressure is the primary condition for spraying the main material is generally controlled between 0.01 and 0.03, if you can evenly with the speed of the gun and evenly spread point is considered qualified. (The actual construction can be properly debugged to their own sense of the most appropriate color pressure standard)
1. Too large: easy to accumulate and can not spray evenly, will cause the flow of hanging, can not achieve the effect of the spray,.
2. Too small: will cause no material, small material, so that the normal spraying can not be sprayed, will affect the spraying effect and construction time.
Third, the air pressure: the air pressure of the gun generally to debug the pressure valve at the end of the gun (pressure valve at the bottom of the intake hole is also the most end of the handle) shall prevail (it is not recommended that another pressure gauge, if the pressure gauge is not well debugged easy to cause a lack of air supply affects the spraying), adjust the air pressure can first rotate the pressure valve clockwise to completely close, and then rotate counterclockwise a circle and a half is the most appropriate air pressure, of course, if the air pressure is not enough at this time If the air pressure is not enough, you can continue to debug in a quarter-turn manner.
1. The air pressure is too large easy to break the main material color point, the spray effect is more blurred and more pinhole color point, color point around the explosion state, the overall effect will be gray and dark, can not achieve the desired effect.
2. The air pressure is too small color point will accumulate flow hanging can not reach the required spraying color point size effect. The effect of the material will be bent and sagging and present the state of airless.
Fourth, the construction environment: 1. base surface treatment must be flat, primer should be evenly rolled to ensure the uniformity of color, otherwise it will affect the main material hair flower, can not make the overall color to achieve consistency. (The spraying method of fire surface primer can refer to the construction method of the required bone material for spraying)
2. Outdoor construction must be selected in the sunny and dry weather construction, air humidity, will affect the drying speed of the paint and the main material will hang affect the construction effect. If you really need construction can be improved by using less spraying more than one method.
Fifth, know the gun: to play a small sample of the gun, for example, the hopper is mainly used to hold the main material, the intake hole is located at the bottom of the handle, adjusting the air pressure valve has been said before, the control of the discharge valve is located at the upper end of the handle, the end of the gun needle thicker that one is, mainly used to control the amount of material, the general control of the material to be adjusted to the right position, too small will tear the color point, too large gun will be no force, generally adjusted to reveal two to Three turns of silk buckle for the appropriate, such as in the case of larger color points can be adjusted appropriately large (generally when the exposed silk buckle is large, and vice versa is small), adjust the spraying width valve, located at the upper end of the control discharge valve that is smaller, according to the construction area can be properly adjusted to the width of the material, clockwise for narrow, counterclockwise for wide. Of course, when too narrow is also easy to cause the accumulation of color dots and tear color dots, too wide to spray out the color dots will be more scattered will also affect the strength of the material, so only appropriate debugging. Nozzle is the main material out of the small mouth when spraying. Pressure handle, located in front of the handle, when spraying to control the role of the material (role in the form of a pistol trigger), the general spraying pressure to the end of the pressure handle, until the pressure does not move, do not allow the half-pressure state, half-pressure state will tear the color point, resulting in insufficient color point. Material gland, generally connected to the gas pipe, when using buckle hopper rotation to not leak prevail.
