pigments basic classification

From the chemical composition of the pigment can be divided into inorganic and organic pigments into two categories, its origin can be divided into natural pigments and synthetic pigments. As a source of natural mineral pigment, such as: cinnabar, clay, realgar, malachite green and heavy calcium carbonate folk painting paint
, Wollastonite, barite powder, talc, mica, kaolin, etc. Biological as a source, such as those from animal: Carmines, natural scale powder; derived from plants are: Garcinia, Alizarin red, indigo and aluminium hydroxide  so on. Synthesized by synthetic pigments, such as titanium dioxide, lithopone, lead, chrome yellow, iron blue and other inorganic pigments and Big Pink, even yellow, phthalocyanine blue, quinacridone organic pigments. Function of the pigment to the classification, such as anti-rust pigments, magnetic pigments, luminescent pigments, pearlescent pigments, electrically conductive pigments. In color, it is convenient and the methods used. This pigment can be divided into white, yellow, red, blue, green, brown, purple, black, regardless of their origin or chemical composition. The famous "Colour Index" (ColorIndex) is used to color classification methods: If the pigment into pigment yellow (PY), pigment orange (PO), Pigment Red (PR), Pigment Violet (PV), Pigment Blue (PB) , Pigment Green (PG), Pigment Brown (PBr), pigment black (PBk), pigment white (PW), metallic paint (PM) and other ten categories, the same number of color pigments are arranged according to the order, such as titanium dioxide as the PW- 6, lithopone PW-5, Lead Chrome Yellow PY-34, quinacridone PR-207, red iron oxide PR-101, Phthalocyanine Blue PB-15 and so on. In order to find the chemical composition, there is another structure number, such as titanium dioxide PW-6C.I.77891, phthalocyanine blue is PB-15C.I.74160, you can make the pigment manufacturers and users to identify the pigments listed The composition and chemical structure of the. Therefore, the pigment in the international import and export trade industry have been widely adopted, some of the domestic paint manufacturers also use this pigment international classification standards. Using color. Each color has a sign pigments, such as white epoxidation of soybean oil  as BA, red for HO, yellow for the HU ...... combined with the chemical structure of the pigment composition code and serial models, such as rutile titanium dioxide BA-01-03, chrome yellow HU-02-02, red iron oxide HO-01-01, lithopone BA-11-01, toluidine red HO-02-01, BGS phthalocyanine blue LA-61-02 and so on.
The pigment contained in the compound according to the classification categories: inorganic pigments can be broken down as oxides, chromates, sulfates, silicates, borates, molybdates, phosphates, vanadates, iron cyanate , hydroxides, sulfides, metal, etc.; organic pigment into the chemical structure of compounds according to azo pigments, phthalocyanine pigments, anthraquinone, indigoid, quinacridone, dioxazine pigments such as polycyclic, aromatic CH pigments and so on.
From the manufacturing point of view can be classified into the titanium pigments, iron pigments, chromium pigments, lead pigments, zinc pigments, metallic pigments, synthetic organic pigments, this classification method has practical significance, often PVC profile stabilizer  a system will on behalf of a professional production of the pigment industry.
From the application point to the classification can be divided into paint pigment, ink pigment, plastic pigment, rubber paint, ceramics and enamel pigments, pigment for cosmetic medicine, art with paint and so on. Various special pigments have some unique properties, in order to meet the application requirements. Pigment production plant can be targeted to professional users recommended a series of paint products.
