Barium calcium carbonate kaolin which zhegaili better
Calcium carbonate is a kind of inorganic compounds, commonly known as CaCO: limestone, limestone, limestone, marble etc.. Main ingredients: calcite, is a kind of compound, chemical formula is CaCO, neutral, basically insoluble in water, soluble in hydrochloric acid. It is common on the earth substances exist in aragonite, calcite, chalk, limestone, marble, Shi Huihua rock, also is the main component of animal bones or shell. Calcium carbonate is an important building material and is widely used in industry. Calcium carbonate is composed of calcium and carbonate ions combine to form, so it is also calcium carbonate.
Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because of the white and delicate, also known as "white cloud soil.". [1] was named after kaolin village in Jiangxi, Jingdezhen province. Its pure kaolin is white, fine and soft, and it has good plasticity and fire resistance. The mineral composition is mainly composed of mineral kaolinite, halloysite, illite, illite, montmorillonite and quartz, feldspar etc.. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of paint, paint, plastic, used for grinding wheel, pencil, soap, cosmetics, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.
The ink consists of major and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous, gelatinous fluid. It consists of binder (resin), pigments, fillers, additives and solvents. The fingerprint brush ink surface gloss after drying in the light, the ability to the same concentration of reflected light. Ink with high gloss shows great brightness on printed matter. The glossiness mainly depends on the kind and property of the ink in the ink, the treatment of the refining process in ink making and the smoothness of the ink film after drying. In addition, the ink gloss by nature pigment ink composition, particle size and shape effect of dispersion; ink penetration, leveling, drying properties of the substrate material and so on.
Kaolin, calcium carbonate and talc powder as a kind of inorganic filler will affect the ink gloss, the most important influence is reflected in the kaolin, calcium carbonate and talc powder in water content, too much water, the influence of ink concentration, which will affect the use of ink printing effect, so the detection of moisture content it is necessary to.
Talc powder, English name PULVISTALCI, white or white like, fine, sand free powder, hand touch greasy. Odorless, tasteless. This product is insoluble in water, dilute ore, acid or dilute hydrogen alkali solution.
