硫酸钡具有化学惰性强，稳定性好，耐酸碱，硬度适中，高比重，高白度，能吸收有害射线等优点，是一种具有环保功能的材料，因此广泛用于各种涂料，中高档油墨，医药合成化工，橡胶、造纸、陶瓷、化妆品等领域。
产品等级BaSO4含量白度
一等品≥98%95%
二等品≥96%92%
三等品≥93%90%
四等品≥90%85%
用途：
1、用于涂料、油漆—可作为油漆、涂料的填料替代沉淀硫酸钡、立德粉、钛白粉、活性二氧化硅等价格较高的原料，适合控制油漆的粘稠度，使产品色泽光亮，稳定好。
2、用于塑料工业—可用于塑料ABS原料的填料，使产品光泽亮力，同时还可以提高产品强度，刚度和耐磨。
3、用于橡胶工业，500目以下产品可大量用于橡胶制品作为填料，降低成本，提高制品硬度、耐酸碱性和耐水性等，并对天然橡胶和合成橡胶有良好的补强作用。
4、用于造纸工业—高细度的重晶石粉可用于白板纸、铜板纸的填料和涂布填料，以提高白度，提高表面覆盖率。
Barium sulfate has the strong chemical inertness, good stability, acid and alkali resistant, with moderate hardness, high density, high whiteness, absorbs harmful rays, etc, is one which has the function of environmental protection material, so it is widely used in all kinds of coating, high-grade printing ink, medicine, synthetic chemicals, rubber, paper making, ceramics, cosmetics and other fields.
Product grade BaSO4 content whiteness
Grade a 98% 98% or higher
Second or higher 96% 96%
Thirds acuity 93% 93%
Fourth taste acuity 90% 90%
Purpose:
1, used for coating, paint, packing instead of precipitated barium sulfate can be used as paint, coating, lithopone, titanium dioxide, activated silica higher raw material prices, suitable control the viscosity of paint, make the product colour and lustre is light, good stability.
2, used in the plastics industry, packing can be used in ABS plastic raw material, make our products shine bright, but also can improve product strength, stiffness and wear resistance.
3, used in rubber industry, 500 mesh can be used for rubber products the following product as a filler, reduce costs, improve product hardness, acid and alkali and water resistance, etc., and the natural rubber and synthetic rubber has good reinforcement effect.
4, used in the papermaking industry, high fineness of barite powder can be used in packing and coated white board paper, bond paper packing, in order to improve the whiteness, improve the surface coverage.
