How to distinguish color paste, color concentrate, color masterbatch and pigment
Color paste, as the name implies, is a kind of pigment concentrated paste, which is developed by using different pigments, through the technology of surface treatment and surface wrapping of pigments, and through a rigorous processing process. According to the different solvents used in color paste, color paste is divided into water-based color paste, oil-based color paste, water-oil general color paste, etc.; according to the different uses of color paste is divided into paint color paste, tape color paste, paper color paste, textile color paste, mechanical color paste, toy color paste, latex products color paste, etc.; according to the different tools used in color paste, people simply divided into factory color paste and machine color paste, etc. The color paste in the natural world is collaborating to dress up the whole world, from small to dressing, daily use, toys, etc., to big to bridges, houses and buildings, etc., all of them are showing colorful colors.
With the rapid development of construction and industry, including hotels, business, landscape, transportation and other areas rarely designed to the color paste field have been significantly into the development of the color paste market, is moving towards the overall, energy-saving development trend, of course, this is mainly manifested in the rapid rise of color paste manufacturers, driving the entire color paste industry tends to be efficient, low-carbon development.
Water-based color paste for coloring, its application areas are very broad, including coatings, leather, printing, paper, latex, textile and other industries, the main service object is the coating industry.
Now the industry class in the “oil to water” water-based color paste will slowly replace the original oil-based color paste in various industries, oil-based will become a thing of the past, water-based environmental protection industry will become the theme of technical exchanges in various industries, to water-based environmental protection development is the transformation of the coating industry is the direction of future expansion.
Color Essence
Metal complex dyes are also called transparent dyes, commonly known as color essence or color powder, is a kind of dyes that can be dissolved with solvents and has a very good compatibility with various resins, so its application range is very wide. Because of its special complex structure, metal complex dyes are different from organic pigments and traditional azo dyes, and have higher gloss and transparency, better weather resistance and stronger fastness; compared with inorganic pigments, metal complex dyes have the characteristics of easy dispersion, easy penetration, easy coloring, brilliant color and good transparency effect. It is mainly used in the following industries:
1) Metal complex dyes for solvent-based inks;
2) Metal complex dyes for printing inks for aluminum foil;
3) Metal complex dyes for printing inks for other paper or metal surfaces (e.g. screen printing);
(4) metal complex dyes for wood coatings;
(5) metal complex dyes for coloring aluminum foil (such as hot stamping materials);
(6) metal complex dyes for transparent coloring of metals (such as low-temperature baking paint for interior decorations)
(7) metal complex dyes for special coatings;
(8) metal complex dyes for ball-point pens and various stationery inks;
(9) metal complex dyes for surface dyeing of plastic products (such as vacuum plating, etc.)
(10) natural and synthetic leather surface coloring with metal complex dyes;
(11) metal complex dyes for shoe polish dyeing.
(12) metal complex dyes for coloring lamp products.
Solvent-based colorants are dyes that are soluble in organic solvents such as aromatics, esters, styrene, methyl methopropionate, etc. (almost insoluble in water).
Color Master Batch
Color Master Batch, also known as Color Master Batch, is a new type of colorant for polymer materials, also known as Pigment Preparation. Color master batch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive, and it is an aggregate made by evenly loading an extraordinary amount of pigment into the resin. It can be called Pigment Concentration, so its coloring power is higher than the pigment itself. By mixing a small amount of masterbatch with uncolored resin during processing, the coloring resin or product can reach the designed pigment concentration.
Colorants
The most commonly heard of food coloring is a kind of pigment, i.e., a food additive that can be consumed in moderation and can change the original color of food to a certain extent. Food coloring, like food flavoring, is divided into two types: natural and synthetic.
The color of food is an important factor in the sensory quality of food. People often use a food additive, food coloring, in the preparation of food. There are two major types of food coloring used: natural food coloring and synthetic food coloring. Before the British invented the first synthetic food coloring aniline violet in 1850, people were using natural coloring to color. As early as before the 10th century AD, the ancients began to use plant-based natural coloring to food coloring, the earliest use of pigment is the Alicorn people of Great Britain, when they used cedar plant pigment to make rose-purple candy. Later, the Toltecs and Amantecs in the Americas successively extracted carmine from female cochineal insects, which was used for food coloring. Since ancient times, China has the habit of making wine, sauce meat and red sausage from red currant rice. The southwestern part of the country uses yellow rice flowers, and the southern part of the country uses the leaves of the ugly rice tree to pound juice to dye glutinous rice for consumption. Food coloring and food additives to improve the color of food. There are natural and synthetic. Natural food coloring is directly from plant and animal tissues extracted from the pigment, generally harmless to humans, such as red currant, chlorophyll, curcumin, carotene, amaranth and sugar color, is part of it. Synthetic food coloring, is made from aniline dyes isolated from coal tar as raw materials, so also known as coal tar pigments or aniline pigments, such as synthetic amaranth red, carmine and lemon yellow, etc.. These synthetic pigments are prone to induce poisoning, diarrhea and even cancer, harmful to humans, so they can not be used more or as much as possible.
Natural pigments are mostly made from natural coloring plants. These colorful plant components, skin, shells, leaves, residue, etc. are often used as a comprehensive use. There are also made by animals, such as purple gum pigment (cochineal pigment), there are made by microorganisms, such as the red pigment. In addition to the caramel color system to sugar substances at high temperatures and heated caramelization, more water or related solution extraction, and then further refining, concentrated and dried. There are also coloring plant components that are dried and crushed for direct application. It is also produced by biotechnological methods such as tissue culture. There are artificial chemical synthesis methods to produce pigments (nature-identical colours) that are identical in chemical structure to natural ones, such as β-carotene, whose safety is stronger than that of the general synthetic pigments.
Natural pigments such as microbial pigments, plant pigments and mineral pigments extracted from animal and plant tissues and minerals are available for consumption and are called natural food colors. Widely used in pharmaceutical food, allowed the use of insect gum pigment, safflower yellow pigment, beet red, paprika red pigment, red currant rice, turmeric, β-carotene, chlorophyll acid copper sodium salt, sauce color, etc.. In the selection of food coloring, its color, taste and smell should strive to harmonize with natural objects or habits
