硫酸鋇
硫酸鋇具有化學惰性強，穩定性好，耐酸堿，硬度適中，高比重，高白度，能吸收有害射線等優點，是一種具有環保功能的材料，因此廣泛用於各種塗料，中高檔油墨，醫藥合成化工，橡膠、造紙、陶瓷、化妝品等領域。
產品等級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、用於塗料、油漆—可作為油漆、塗料的填料替代沉淀硫酸鋇、立德粉、鈦白粉、活性二氧化矽等價格較高的原料，適合控制油漆的粘稠度，使產品色澤光亮，穩定好。
2、用於塑料工業—可用於塑料ABS原料的填料，使產品光澤亮力，同時還可以提高產品強度，剛度和耐磨。 3、用於橡膠工業，500目以下產品可大量用於橡膠制品作為填料，降低成本，提高制品硬度、耐酸堿性和耐水性等，並對天然橡膠和合成橡膠有良好的補強作用。
4、用於造紙工業—高細度的重晶石粉可用於白板紙、銅板紙的填料和塗佈填料，以提高白度，提高表麵覆蓋率。

Product characteristics and USES
Barium sulfate
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.
