Nano Barium Sulphate

Using high-tech nanotechnology, the nano barium sulphate is organic and
inorganic dense coated powder. Narrow particle size distribution, good chemical
stability, high degree of activation, good dispersion, high whiteness and other
characteristics. High purity, acid resistance, alkali resistance, high
temperature resistance and no loss of gloss, good salt spray resistance and
weather resistance.
 
Barium sulphate nanopowder can be widely used in various water-based paints,
water-based wood paints, inks, plastics and other products. It can maintain the
transparency of the products. The barium sulphate powder can be used as a
transparent masterbatch of barium sulfate, and it can significantly improve the
surface gloss, paint film hardness, weather resistance, and auxiliary Focus on
and reduce costs.
 
Production process:
The selection of barite with higher composition is produced by ball milling
classification technology.

Applications:
Bulk nano barium sulphate powder can be used in powder coating, paint coating,
ink, rubber, plastic filler, also can be used in paper, ceramics and other
fields.
 
Main functions:
As a filler for paints and coatings to replace Lide powder, titanium dioxide,
active silica and other raw materials with higher prices, it is suitable for
controlling the viscosity of paint, making the product bright and stable.
Used as filler for plastic ABS raw materials to enhance product gloss, high
temperature resistance, UV resistance, strength, stiffness and wear resistance,
and anti-impact, anti-cracking; For thin films, when the filling amount is not
higher than 10%, the transparency is basically not affected; Using its
dispersion, it plays the role of pigment dispersant in the color masterbatch,
improves fluidity, gives the material excellent mechanical properties, and can
effectively save the amount of pigment in the color masterbatch.
Can be widely used in rubber products as fillers, reduce costs, improve
product hardness, acid and alkali resistance and water resistance, and natural
rubber and synthetic rubber has a good reinforcing effect to prevent surface
aging; High degree of activation, good compatibility with the matrix, close
combination, improve the wear resistance of the modified material.
For the paper industry - high fineness barite powder can be used as filler
and coating filler for whiteboard paper, copperboard paper to improve whiteness
and ratio coverage, so that the paper does not mix color under high-speed
copiers.
Because of the high purity of nano-barium sulfate, less impurities, does not
contain some harmful impurities to elastomers, especially suitable for use as
an elastomer filler. Used in ceramic fabrics, glazes, so that the product
hardness is high, white jade, bright luster.
