Description

Mineral substance pigment grinder is used in art pigment preparation
Technical Field
The invention relates to the technical field of mineral pigment grinding equipment, in particular to a mineral pigment grinding device for preparing art pigments.
Background
A pigment is a substance that changes the color of reflected or transmitted light due to wavelength selective absorption. The materials selected and developed by man for use as pigments generally have special properties that can colour other materials. The pigment must have a high tinctorial strength relative to the material it is colouring and be able to assume a stable solid state form at ambient temperature.
Most pigments are soil and mineral pigments and biological pigments. Mineral pigments are inorganic pigments, are a class of inorganic substances, belong to inorganic colored pigments, and are mainly derived from two types: one kind is prepared with natural ore and through mineral separation, crushing, grinding, grading and refining, and is used mainly for painting, handicraft, antiquing, cultural relic repair, etc. The inorganic pigment is a chemical synthetic pigment prepared from natural mineral products through a series of chemical treatment processes.
The mineral pigment is generally red, yellow, black, etc. In 3, the colors can be blended to obtain colorful colors according to the color mixing principle. Mineral pigment is directly prepared by crushing and grinding ore, is not prepared, mineral color powder sold in the art supplies market can be prepared into pigment by self, the traditional Chinese painting color is prepared by adding peach gum, the rock color painting is prepared by using gelatin, oil painting color can be prepared by adding dry vegetable oil, and the egg yolk emulsion can be prepared into the Tepela pigment.
Modern mineral colors are developed and enriched on the basis of ancient mineral colors, and are dramatically developed in variety besides maintaining the existing mineral colors of ancient times, particularly the mineral colors are developed from several to hundreds. In the aspect of soil pigment, the artificial soil mineral color developed by clam powder, high-quality light-resistant high-grade pigment and dye according to a certain formula greatly overcomes the limitation of ancient mineral colors. The production and development of new rock mineral colors are a great progress, and hundreds of abundant hues greatly supplement the limited hues and varieties of natural mineral colors.
The colour of the mineral powder is called streak, which is an important determinant in identifying what mineral can be coloured. During testing, the minerals are placed on an unglazed porcelain plate, and after the minerals are lightly rubbed, the colors of the powder traces left by the minerals are seen for identification. The streak eliminates false color interference and also reduces the influence of the color, and highlights the self color of the mineral, which is relatively fixed. The method is often used as a reliable basis in the identification process.
A grinding device is used in the pigment processing process, the main purpose is to change the granularity of materials, so that large materials are crushed and ground into powder, but the large materials are mostly irregular blocks, the grinding effect of the existing grinding device is not good, and the product quality of prepared pigments is influenced.
