Barite - Barium Sulphate
It is a high quality drilling grade Barite (Barium Sulphate) used to increase the density of drilling fluids. It is the most widely used drilling weight material due to its high specific gravity. It meets API 13A requirements.
Barytes (or barite) is a naturally occurring mineral form of barium sulphate. It is extracted by both surface and underground mining. Its main properties are its high specific gravity 4.2 – 4.5, very low solubility; it is non-toxic, and also chemically and physically non-reactive, low abrasiveness and opaqueness to x-rays.
Oil well Drilling
Barite is used as a weighing agent in oil well-drilling fluids to counteract certain pressures that result from well drilling operations. In this process, Barite is crushed and mixed with water & other materials. It is then pumped into the drill hole. The weight of this mixture counteracts the force of the oil and gas when it is released from the ground. This allows the oil and gas rig operators to prevent the explosive release of the oil and gas from the ground.
Paper-Making Industry
In the paper industry, high-refined barites powder can be used as the filling of white paperboard and coat paper, improve the whiteness and percentage of coverage.
Cosmetics:
When used in cosmetic industry, the properties of barite powder such as high whiteness, gentle and harmless to skin allow it to replace titanium dioxide.
White pigments
Barite is a key player in preparing white pigment (lithopone) which is a mixture of barium sulphate and zinc sulphide. This pigment is used in making white paint that is used to give a chic appearance to wooden artifacts.
Paints, Enamel and coatings
In dope and painting, it can be used as a filler and can take the place of some expensive material such as basofor, crypton, titanium dioxide, activity, monox etc. Control the viscosity of the paint compatibly to make the products with bright color, good stability.
Adhesives & Sealants
Barite is dense, inert, sound & radiation-absorbing fillers for special sealants and adhesives. It is included where a higher weight is wanted in the adhesive.
Rubber
In rubber industry, the products less than 600 mesh is used as the filling of rubber products to save cost. It improves the intensity, acid, alkali and water proof. The grinded barite powder is important additive to improve its hardness, wear resistance and anti-aging properties. It makes better the reinforcing action of caoutchouc and synthetic rubber too.
Plastic Industry
In plastic industry, it is used as the filling of plastic ABS (Acrylonitrile - Butadiene - Styrene) to make the products with bright color. It boosts the intensity, stiffness and abrasive resistance of the plastic.
Pharmaceutical Industry In medicine, it can be used as barium meal material for the intestines and stomach reflection, and also the filling for plaster.
Advantage:
• It does not react with other drilling Fluids or hamper their functioning
• It is chemically inert and insoluble
