The Pigment Has A Hiding Power Aug 03, 2017

Pigment is a decorative and protective effect of colored material, it is insoluble in water, oil, resin and other media, usually in a dispersed state used in ink, plastic, rubber, ceramics, paper and other industries, so that these products show color The It has a hiding power, color strength, relatively stable light, commonly used in the preparation of coatings, inks and coloring plastics and rubber, Pigment so it can be called colorants.

Pigments differ from dyes in that general dyes can be dissolved in water or solvents, and pigments are generally insoluble in water. Dyes are mainly used for dyeing textiles, Pigment but this distinction is not very clear, because some dyes may also be insoluble in water, and the pigment is also used for textile coating and printing liquid coloring. The chemical structure of organic pigments is similar to organic dyes and is therefore generally regarded as a branch of dyes. Pigments from the chemical composition to classification, can be divided into inorganic pigments and organic pigments two categories, its source can be divided into natural pigments and synthetic pigments. Pigment Natural pigments from the source of minerals are cinnabar, red clay, realgar, malachite green, heavy calcium carbonate, wollastonite, talcum powder, mica powder, kaolin and so on. And other plants from the vine, alizarin red, indigo and so on. Synthetic pigments such as inorganic pigments such as titanium white, zinc barium white, lead chrome yellow, iron blue, iron red, Pigment red dan and other organic pigments, and organic pigments such as heavy powder, azo yellow, phthalocyanine blue and quinacridone. Pigment function can be divided into anti-rust paint, magnetic pigments, luminous pigments, pearlescent pigments, conductive pigments and so on. Color classification is a convenient and practical method, Pigment the pigment can be divided into white, yellow, red, blue, green, brown, purple, black, etc., without regard to its source or chemical composition.

 The famous "dye index" is the use of color classification methods, such as the pigment is divided into pigment yellow (PY), pigment orange (PO), pigment red (PR), pigment purple (PV), pigment blue (PB), pigment green (PG), pigment brown (PBr), pigment black (PBk), pigment white (PW) and metallic pigment (PM). The same color pigments are numbered in order, such as PW-6, zinc White PW-5, lead chrome yellow PY-34, quinacridone PR-207, iron oxide red PR-101, phthalocyanine blue PB-15 and so on. In order to find the chemical composition, Pigment and another structural number, such as titanium dioxide for the PW-6C.I.77891, phthalocyanine blue is PB15C.I.74160, can make the paint manufacturers and users can identify the included Pigment composition and chemical structure, so in the international pigment import and export trade have been widely used.
