All kinds of monochrome paint (also known as primary paint) varieties, although quite a lot, but still far from meeting people's needs, which requires painters in the actual work, the use of existing primary paint to match more colorful colors.
color matching is a complex and detailed task, as there are so many colors that it is necessary to understand the performance of various pigments and to make accurate judgments about color differences.
Manual preparation of complex paint, mainly based on practical experience, according to the need for color paint model to identify the existence of several monochrome composition, the approximate proportion of each monochrome is how much, do small sample deployment experiments, and then make preparation, but must also be based on the basic principles of colorology
C.
.
below to introduce the color adjustment and paint color ten tips -
first, color adjustment need to be careful, generally try small samples, the initial number of color coatings, and then according to the results of small samples to make large samples.
first adjust the secondary and secondary colors in a small container.
2, first add the main color (in the color matching volume, color with little color force), and then the dyeing force of the dark color (or color matching) slowly intermittently added, and constantly stirring, at any time to observe the color changes.
, "from light into the deep" especially when adding coloring strong pigments, avoid excessive.
, when color matching, there will be subtle differences between the paint and the dry coating color.
colors are generally lighter when wet film, when the paint is dry, the color deepens.
So, if the sample is a dry sample, then the color paint needs to wait for drying before color comparison
, in advance should understand the original color in the complex paint floating degree and paint changes.
6, the deployment of complex color coatings, to choose the same nature of the paint mutual deployment, solvents should also be mutually soluble, otherwise due to the paint mixing is not good, will affect the quality, and even the occurrence of layering, extraction or collation phenomenon, can not be used.
7, because the color often comes with a variety of different color head, such as green, generally with green head yellow and yellow head blue;
with purple, should be red with red head blue and red with blue head;
with orange, should be red with yellow head and yellow with red head.
, pay attention to the color preparation process, but also to add which auxiliary materials, such as drying agents, curing agents, thinners and other colors, so as not to affect the color.
9, in the deployment of gray, green and other complex paint, due to a variety of pigment preparation, pigment density, different amount of oil absorption, it is likely to occur "floating color" "flowering" and other elephant phenomena, when appropriate to add trace amounts of surfactants or leveling agents, anti-floating colorants to solve.
as usual to add 0.1% of silicone oil to prevent and control, foreign companies produce a variety of surfactants, need to be clearly used in what solvent system, the amount of addition is generally 0.1-1%.
10, the use of color paint film slightly transparent features, the choice of suitable substrate color can make the color of the paint than the original paint color more distinct, which is based on the principle of natural reflection absorption, the background color and the primary color superimposed after the production of a color, paint engineering called "color transmission."
such as yellow primer can make red bright, gray primer makes red red red, positive blue primer can make black black brighter, water blue primer makes white cleaner and whiter.
cream, pink, ivory, sky blue, white primer.
