Application of Precipitated Barium Sulfate in coatings
Application of precipitated Barium sulfate in coatings
Barium sulfate is widely used in all kinds of paint, rubber, ceramics, papermaking, printing ink industries, such as barium sulfate is a kind of white, gray crystal powder, has the very good acid and alkali, stability, non-toxic, moderate hardness, environmentally friendly materials, barium sulfate is mainly used in coating industry, the following is the small make up for your detailed introduction.
Precipitate barium sulfate in rubber, plastic, paper, paint, ink, coating and other industries used as filler, brightening agent, weighting agent. Barium sulfate used for interior and exterior wall decoration can effectively shield X - ray and Y - ray, can effectively prevent blocking ray leakage.
The effect of barium sulfate on titanium dioxide and pigment in plastic gasket can reduce the amount of pigment and save about 10% of the cost.
Barium sulfate (about 25%) is applied to the surface of PP like ABS, without affecting the existing characteristics of PPV, providing gloss and high hardness surface.
Barium sulfate can reach 80% of its weight filling rate, applied to drain pipes, sound boxes, sound can effectively isolate noise, noise, barium sulfate N applied to curtain can increase weight. Used for home appliance shell can improve gloss, good hue, scratch resistance, size stability and other advantages.
Barium sulfate in the coating is used as a physical pigment in the coating, to improve the thickness of the coating, wear resistance, water resistance, heat resistance, surface hardness, impact resistance and so on play a very important role.
In addition, barium sulfate is highly reflective in the wavelength range of 300-400 microns, which can protect the paint film from light aging. It is an effective and inexpensive white inorganic light stabilizer. Because of its low oil absorption, it has a high filling amount, so it can reduce the cost of paint. It can be used for water-based paint, primer, intermediate paint, oil paint and so on. Using it to replace 10%-25% of titanium dioxide in waterborne coating, the results showed that the whiteness increased and the covering rate did not decrease.
