硫酸鋇具有化學(xué)惰性強(qiáng)，穩(wěn)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(yōu)點，是一種具有環(huán)保功能的材料，因此廣泛用于各種涂料，中高檔油墨，醫(yī)藥合成化工，橡膠、造紙、陶瓷、化妝品等領(lǐng)域。

產(chǎn)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、用于涂料、油漆—可作為油漆、涂料的填料替代沉淀硫酸鋇、立德粉、鈦白粉、活性二氧化硅等價格較高的原料，適合控制油漆的粘稠度，使產(chǎn)品色澤光亮，穩(wěn)定好。
2、用于塑料工業(yè)—可用于塑料ABS原料的填料，使產(chǎn)品光澤亮力，同時還可以提高產(chǎn)品強(qiáng)度，剛度和耐磨。
3、用于橡膠工業(yè)，500目以下產(chǎn)品可大量用于橡膠制品作為填料，降低成本，提高制品硬度、耐酸堿性和耐水性等，并對天然橡膠和合成橡膠有良好的補(bǔ)強(qiáng)作用。
4、用于造紙工業(yè)—高細(xì)度的重晶石粉可用于白板紙、銅板紙的填料和涂布填料，以提高白度，提高表面覆蓋率。

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.
