Special barium sulfate 1250

Special barium sulfate, barium sulfate industry, Shanghai barium sulfate production plant, the proportion of barium sulfate, 4.3, barium sulfate (precipitation / superfine / special) Yue Jiang card - special barium sulfate is the use of advanced physical production technology, through a special modification , performance is more superior whiteness after modification, grain through a narrow and uniform distribution, dispersion, ultra-fine, ultra-clean products are high quality grades of similar products. Can absorb X-rays, γ-rays, and given the high density of the material and surface finish, which is widely used in paint, ink, paint, plastic, rubber, chips, friction plates, ceramics, glass, electronics, cosmetics, medicine, food and other fields . First, the main criteria and characteristics of chemical barium sulfate (BaSO4) / tailor-made products White powder Packing 25kg woven bag / kraft paper, 1000kg sack Main features using advanced physics technology production, through a special modification, performance is more superior, change whiteness after sex, grain through a narrow and uniform distribution, dispersion, ultra-fine, super clean and so on. Applications can absorb X-rays, γ-rays, and given the high density of the material and surface finish, which is widely used in paint, ink, paint, plastic, rubber, chips, friction plates, ceramics, glass, electronics, cosmetics, pharmaceuticals, food and other fields. Second, the quality indicators Item Unit Index First grade barium sulfate content of a superior grade dispersion% ≥98 ≥97 2% ≤ 15um ≤20um 3 Water soluble content% ≤0.3 ≤0.5 4 Moisture% ≤0.15 ≤0.15 5 aqueous suspension PH value of 6.5 to 8.0 6.5 to 9.0 6 oil absorption (according to different fineness)% g / 100g 15-25 15-25 7 Fineness (30um) sieve residue% ≤0.05 ≤0.1 8 Whiteness% 92-95 the proportion of 4.0-4.5 4.0-4.5 90-939 fineness: 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, 2000 mesh, 3000 mesh, 6000 mesh 8000 mesh 12500 head, 15,000 head (fineness according to customer request)
