Yuan jiang card - extinction barium is to adopt advanced production technology at home and abroad, using the pure physical and chemical processing method to select barite for superfine processing, make its have the following special features:
1. More strong colors: extinction barium good dispersibility, played a maximum covering power, at the same time as the carrier to make pigments efficient dispersion of pigment and obtain uniform color;High purity of whiteness make brighter color is pure;Micro crystal structural characteristics and high refractive index, make more colorful.
2. A more stable system: extinction barium good chemical inertness, make all kinds of basic environment stable system;Ultrafine particle surface energy is strong, good compatibility, can with other organic cross composite, strengthen the binding force;Evenly dispersed micro monomer, stable suspension in the system, do not produce flocculation and precipitation.
3. The more solid film: extinction barium high density, good wear resistance;Ultrafine particles of strong surface can make coating and substrate with stronger;Uniformity of superfine particles.Make the film more smooth, more strong and durable.
4. More excellent weatherability, extinction barium good chemical inertness, waterproof acid resistance, resistance to acid rain, high temperature and corrosion resistance;At the same time have special ray absorption function, greatly improve the weatherability of coatings.Two kinds of products are divided into 325 mesh, 400 mesh.
USES:
1, used in paints, paint can be used as paint, paint filler instead of precipitated barium sulfate, lithopone, titanium dioxide, active silica and other high prices of raw materials, suitable for paint control the viscosity, make the product colour and lustre is light, good stability.
2, used in the plastics industry - can be used for packing, plastic ABS material can also be used in the chip and mahjong, make our products shine bright, but also can improve the product strength, stiffness and wear resistance.
3, used in rubber industry, below 400 mesh products for a lot of rubber products as a filler, reduce costs, improve product hardness, acid, alkali and water resistance, etc., and the natural rubber and synthetic rubber with good reinforcing effect.
4, used in the papermaking industry - high fineness of barite powder can be used for packing and coated white board paper, bond paper packing, in order to improve the whiteness, improve the surface coverage.
