La description

Uses: Added fillers, barium sulfate from the days of good physical and chemical properties, has been widely used in powder coating, paint, ink, batteries, rubber, glass, cosmetics, and other areas of friction materials is an inexpensive material. Performance: This product is white powder, non-toxic, melting point ***0 ℃, is almost insoluble in water, ethanol and acid. Has a strong chemical inertia, good stability, acid and alkali, moderate hardness (Mohs hardness **3.5) high gloss, high brightness, can absorb the harmful rays X and other benefits Testing items GB/T********6 Measured standard Barium Sulfate (dry basis)%≤ *8.0 *8.0 **5 ℃ volatile %≤ 0.3 0.*0 Water soluble %≤ 0.3 0.*5 Fe content %≤ 0.**4 0.**3 Whiteness %≥ *4 *6 Oil Absorption Value （g/**0g） ****0 ****0 PH value (**0g / L suspended solids)） 6.**9.0 6.**9.0 Fineness (*5μm test sieve residue)%≤ 0.2 0.*1 Package weight kg *5 Test Method: 1、 BaSo4 content was measured by the outgoing department measured 2、 Whiteness GB/T********6 standard method based on measured 3、 Moisture produced by Shanghai Precision Scientific Instrument measured moisture meter 4、 Oil absorption GB***1.****8 standard method based on measured 5、 Specific surface area of Europe and the United States by the OMEC-LS**0 laser particle size analyzer measured g 6、 The average size of Europe and the United States by the OMEC-LS**0 laser particle size analyzer measured g
