Compound fertilizer refers to chemical fertilizers containing two or more nutritive elements. Compound fertilizers have the advantages of high nutrient content, few auxiliary components, and good physical properties. For balanced fertilization, improve fertilizer availability and promote The high and stable yield of crops plays a very important role. Compound fertilizer pigments are pigments that are added to achieve the desired color of the fertilizer.
Red pigments that can be used for compound fertilizers: 3117 bright red(pigment red 22), golden red C(pigment red 53:1), permanent red, sapphire red(pigment red 57:1), brilliant red, strong red, etc., yellow pigments include light fast yellow 10G(pigment yellow 3), permanent yellow, benzidine yellow, permanent Fast yellow 2GS(pigment yellow 14), permanent yellow HR(pimgnet yellow 83), etc., permanent orange, phthalocyanine green, and phthalocyanine blue. These pigments are bright in color and easy to disperse. They are easily decomposed under the light after being applied to soil.
Seed coating refers to the use of adhesives or film-forming agents, using a specific seed coating machine, fungicide (fungus), pesticides, micro-fertilizer (abbreviation of trace element fertilizer), plant growth regulators, colorants or Fillers (also known as fillers, fillers, fillers) and other non-seed materials are wrapped around the seeds to achieve a spherical or substantially original shape of the seeds, improve stress resistance, disease resistance, accelerate germination, and promote growth. Seedling, a seed technology that increases yield and quality. Pigment Yellow 151 is suitable for high-end industrial coatings, automotive primers (OEM), and can be combined with phthalocyanines and inorganic pigments, and can also be used for coloring printing inks on polyester laminated plastic films. Pigment Orange GP(pigment orange 64) is a substance that can make objects dye. Pigments are soluble and insoluble, distinguishing between inorganic and organic. Inorganic pigments are generally mineral substances. Humans have long known the use of inorganic pigments, using colored soil and ore, to paint and smear the body on rock walls. The seed coating agent (characteristics: water permeability and air permeability) can be quickly cured into a film, so it is not easy to fall off. After the seeds coated with the seed coating agent are sown (type: one of crop cultivation measures), they can quickly inflate by absorbing water. With the gradual development of the embryo in the seed and the continuous growth of the seedling, the seed coating agent will slowly release the various effective ingredients contained in it, and it will be gradually absorbed into the body by the seedling, so as to prevent and control diseases and insect pests at the seedling stage, promote growth and development, and increase crop yield. the goal of. Seed coating has been listed as a key agricultural technology project in China.
According to the characteristics of the seed coating pigment, the corresponding varieties are light-fast red BBS (Pigment Red 48: 3), Permanent Red F2R (Pigment Red 2), Permanent Red F4R (Pigment Red 8), and 3117 Bright Red (Pigment Red 22), 3132 red powder (Pigment Red 21), sapphire 57: 1, Brilliant Red 6B, etc. There are also a few yellow varieties that are resistant to light yellow 10G (Pigment Yellow 3). Pigment Yellow 138 organic pigments are generally obtained from plants and marine animals, such as madder blue, garcinia cambogia, and ancient Roman purple from shellfish. It is mainly used in coatings, inks, printing and dyeing, plastic products, papermaking, rubber products and ceramics. With the rapid development of downstream industries, the demand for pigments is constantly expanding, and the development prospects of China's pigment industry are very broad.
