    Colorful paint coloring techniques
    multicolored paint color is by dispersing the color grain matching, through spray gun spray molding to achieve a realistic imitation stone effect. Colorful realicity to do a good job, color matching and particle size matching is the key, color matching includes the choice and matching of the same color background color, continuous phase particle color matching, continuous phase particle size matching.
    the choice and matching of the same color primer
    to get a need to color model, first of all, you need to determine the color of the same color background, the color of the same color background is a distant look when the model reflects the color

    . Choose a good color base color in addition to increasing the final realistic color of color paint, can also reduce the amount of paint, the same color background color also need to take into account the color dispersion phase particles of the main color, the contrast is not too strong, and the final color than the model itself to see the color slightly lighter.
    Multicolor particle color configuration
    First of all, according to the color of the model color color depth to choose different titanium content of the substrate, transparent and translucent selection of 0% titanium white substrate and cover good solid color selection of 1% titanium white substrate, the middle color can be used 0% titanium white and 1% titanium white base for mixing and compounding.
    is the choice of color paste, generally try to choose inorganic iron color paste, as little as possible the use of bright organic color paste.
    1. Because marble is generally very bright colors, do not need to use bright organic
    ; 2. Organic color paste tends to have a high amount of oil absorption, more surfactants are needed for grinding, these surfactants will affect the stability of colorful continuous phase particles;
    3. Inorganic color paste has better weather resistance, which is conducive to extending the service life of multicolor paint.
    In addition to continuous phase particle color adjustment also need to control the total amount of color paste added, the total amount of general color paste should not exceed 8% of the base paint, it is best not to exceed 5%, if it is encountered very dark color, color paste needs to be added more time, you can adjust the color. After, punch some emulsion into, dilute the color base paint solid, and then fine-tune the color, adjust the viscosity to get the ideal effect, of course, it is best to control the titanium content of the toning substitut by covering the amount of color paste.
    Finally try to control the number of continuous phase particle color, generally 5-7 best, too little often no marble layer effect, too much increased the workload and increased the second replenishment of the color reproduction difficulty.
    colorful paint spraying techniques
    multicolored paint must use a special spray gun, in fact, ordinary spray gun plus a pressurized storage tank, pressurized storage tank through a soft leather pipe connected to the spray gun, storage tank market is commonly used in 2L, 10L, in a small amount of spray area can be placed in 1L storage tank loading bucket to reduce waste.
    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 to open the reservoir filling.
    In addition to pressurized storage tank cover there is also an air pressure 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 color 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.
    color spray gun generally use ordinary 3.5mm-4.0mm spray gun can be.
    three knobs behind the spray gun are first fan-adjusted, i.e. the size of the material area at the time of spraying is adjusted through it, and the second is the amount of paint, and the position of the quick joint is adjusted. Through it controls the gap between the gun top needle 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 spewed out, 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 of the pattern is not round with a small tail phenomenon.
    In the construction should also pay attention to the distance between the spray gun and the construction wall, generally 30 to 1000px range is appropriate, too large particles prone to falling and unable to spread, too close particles are easy to be sprayed or smashed into the wall of the pattern is not round with a small tail phenomenon. In addition, in the construction process should try to walk the gun continuously, a molding, reduce point spray and replenishment spray. After the final construction, be sure to clean the gun, storage should not be the pressure tank pressure bucket cover spin very tight, to prevent premature damage to the gasket.
    color paint spraying notes
    colorful paint is now on the site there are two kinds of construction, but the overall construction process and process is similar.
    1. Water bag sand for two spray into (lychee surface, fire surface) imitation stone paint, in order to imitation stone effect more realistic once full spray, once for the point spray effect.
    2. The other is the normal plane effect.
