Definition of paint The so-called coating is a substance that has fluidity, is coated on the surface of the object to form a thin coating film, drying, curing, firmly bonded to the surface of the object, plays a role in protecting the object and increasing aesthetics and other special functions, constituting a continuous coating film. As the definition says, the role of paint is: protective, aesthetic, special role.

(1) Convert residual ink into gray-black ink

 

According to the principle of color science, the hue of inks that are complementary colors will change to gray-black (red + green, yellow + blue-violet). Therefore, we can use this principle to use the method of mixing spot color ink, the inks that are complementary to each other are mixed into gray-black inks, and they are added to black ink in a certain proportion and used as black ink. In the operation, it should be noted that even the remaining oil belongs to the prepared spot color ink, so there will be a certain color cast, and the complementary color ink biased to the color should be added according to the color cast. This method is not suitable for use in the conversion of light-colored inks, and the composition of the ink should be considered, and it should be used reasonably in accordance with the principle of homogeneous mixing.

 

(2) Convert the residual ink into similar color ink

 

The hue of the ink can be divided into gray, black, white, magenta, red, yellow, green, blue, cyan, blue-violet, etc. as a whole, and other colors can be changed from these basic colors. Therefore, even if there are thousands of products, countless colors, you can classify by basic hue. Moreover, there are many similar colors among the many colors, and some even have the same color. In particular, water-soluble and solvent-based inks are more suitable for this method due to their easy mixing and easy filtration.

 

(3) Conversion according to the ink formula

 

The first thing to do is to unify the form of the ink formulation, preferably in percentage. Because the percentage formula is used, it is more helpful to compare between formulas, so as to find the correlation of ink color, and it is convenient to identify the degree of color deviation between different formula inks to determine whether it can be converted into each other. Using this method, we need to do a good job of sorting, classifying, and archiving formulas at ordinary times, so that it is more convenient to find ink formulas of similar hues in use.

 

(4) Conversion according to the ink color card

 

This scheme is generally used for the conversion of inks with unknown ink formulations, and ink color cards can be made by scraping or patterning to facilitate the analysis of ink composition. You can also find inks of similar colors according to the color of the ink color card, so that the remaining ink can be converted into the corresponding color ink according to the allocation method of spot color ink. The method of using residual ink conversion seems to be easy, but in fact requires the operator to have a wealth of color science knowledge and flexible use. Printing plants should pay attention to the establishment of ink formulas, color cards and corresponding identification files, so that the remaining ink can be quickly and accurately used, so as to reduce ink loss, reduce waste and save costs.

Building exterior wall decoration is constantly evolving and progressing, from the original ecology of green bricks and green tiles, to tiles, wall paint and various decorations, wall decoration is constantly developing to meet people's pursuit of beauty. Today, let's take a look at the development process of our exterior wall paints, real stone paint, rock chip paints and colorful paints.

 

Real stone lacquer

Also known as imitation stone paint, the building industry standard is called synthetic resin emulsion sand wall architectural coating, which is a thick architectural coating prepared by using synthetic resin emulsion as the base, natural colored sand of different particle sizes as aggregate, and adding various additives. Real stone paint was developed on the basis of traditional colored sand paint in the eighties of the twentieth century. Compared with traditional pasted tiles and dry-hanging stone, real stone paint is favored by developers because of its obvious advantages such as convenient construction, lower cost, and the closest decorative effect to stone. However, the similarity of real stone paint in imitating granite is not ideal. Rock chip paint

Rock chip paint is developed on the basis of real stone paint, which mainly makes up for the shortcomings of low similarity of real stone paint imitating granite. Due to the addition of synthetic rock chips of different sizes and colors, the color and size of rock chips can be controlled manually, and different rock chips can be matched according to the granite effect, so that the degree of simulation is greatly improved on the basis of real stone paint. Although the simulation degree of granite is improved compared with real stone paint, there is still room for further improvement, and at the same time, because real stone paint and rock chip paint are colored with natural colored sand, there are color differences in different batches of natural colored sand, which in turn causes a certain color difference between real stone paint and rock chip paint batches.

 

Water in water

With the improvement of the water-based requirements of coatings, water-in-water multicolor coatings have become a research hotspot. Water-in-water colorful paint has a long research history, the product technology is basically mature, the storage stability performance reaches six months, and the water resistance can meet the use of exterior walls. The water-in-water multicolor can be made by choosing the modeling layer to make different effects, such as flat and rough surface effects. There are more options than rock chip paint, and the degree of simulation is higher, which can reach 90-95%.

 

 

Water-in-water sand

Water-in-water sand is a novel high-grade exterior wall decorative coating after water-in-water colorful paint and real stone paint, which adopts the method of coating natural colored sand in water-in-water colorful points, so that it has both the high fidelity of multi-colored paint and the texture of natural real stone paint. In order to meet the diversified needs of the market, "stone flavor" has been the mainstream in recent years. According to market statistics, in the past few years, water-in-water sand has replaced ceramic tiles and dry-hanging stone, and the current flat coating and real stone paint coating have slowly replaced it as the preferred exterior wall decoration material for medium and high-end buildings. After market development and development, the technical stability of water-in-sand multi-color coating has reached reliable standards, the stability of the protective glue in the formula system has reached the strict requirements of customers who can continuously produce large-scale, and the storage stability of the multi-colored coating produced (can be guaranteed for 10 months) and the construction stability are super good, which has been highly recognized by the society. The particles in sand are super controllable, and the softness and hardness of the particles can change with the change of formula. In terms of spraying, the effect of imitation stone can be achieved with one spraying, and the ultra-high degree of simulation and realism of imitation stone can be shown in two sprays. The coating industry is constantly developing rapidly, and new coating products are also updating and iterating, moving in a better direction. The quality of the product will be the foundation of the development of the enterprise!
