GRAPHITE POWDER/FLAKES

OXEECO manufactures of high purity Natural and Synthetic Graphite Powders & Flakes. Our track record of successful co-operative projects over 4 decades with various customers testifies to our ongoing commitment to provide products and services specifically suited to meet their individual needs. Rigorous control over raw materials and process conditions assure consistent quality. The unit has been able to correlate the unique & diverse properties of the Graphite from different mines to various applications providing enhanced benefits to its customers. PROPERTIES Graphite is an allotropic form of Carbon. Natural Graphite has a low coefficient of thermal expansion, low modulus of elasticity and high thermal conductivity. These combine to produce excellent thermal shock resistance through careful grade selection. At room temperature, Graphite will resist attack by many acids, alkalis and corrosive gases such as Chlorine, Helium and Hydrofluoric acids (at high temperatures, a reducing or neutral atmosphere is recommended). The electrical conductivity of graphite increase from room temperature to 500°C and then decreases till about 3500°C. As the temperature increases, the electrical conductivity becomes superior to that of more conductive metals such as Copper and Aluminium. Graphite is non-hygroscopic and an excellent extinguishing agent. It does not combine with Oxygen below 600°C. Graphite crystallizes in a hexagon system. Data obtained from X-ray diffraction studies indicate that the length of the hexagonal prism is 6.78A°units. The distance between atoms in adjacent basal planes is 3.35 A° units. The orientation of the crystals determines the structure (flaky, crystalline or amorphous). Broadly speaking, the various grades of Graphite manufactured are :

STRUCTURE : AMORPHOURS OR CRYSTALLINE OR FLAKES

 

GRAPHITIC CARBON: 94-95%, 96%, 98%, 99% 99.5% and 99.9%

 

PARTICLE SIZES: +40/+50, +80, -100, -200, -325 Mesh, average particle size of 30 Microns, 20 Microns, 5 Microns and 3 Microns.

 

Depending upon the customer’s requirement, the correct purity and particle size distribution can be manufactured.

In industry, conditions like extremely high temperatures and pressures, gritty atmospheres and corrosion due to chemicals are quite common. Our Lubricote is a highly stable suspension of pure, ultrafine graphite particles in various liquid media: Oil, Water and Solvents. The extraordinary properties of Lubricote are a result of the unique physical structure of graphite which is an allotropic form of carbon. The sub-microscopic particles of graphite in Lubricote are carried to the surface requiring lubrication where, under the existing conditions of high temperatures and pressures, the carrier medium is displaced, leaving the graphite in a tenacious film. This film fills up even microscopic machining in-accuracies and prevents metal-to-metal contact and shear. In addition to its manifold uses as a lubricant, Lubricote can be used to form electrostatic shields and conductive coatings because graphite is a good conductor of electricity. You can also use it for impregnating porous articles such as fabrics, ceramics, paper, packing materials and sintered bearings.

Lubricote-X is a dispersion of colloidal graphite in refined mineral oil. It is normally blended with mineral oils to lower concentration for various uses. You can also use it undiluted to provide lubrication in particularly severe conditions.

Lubricote-Z is a homogenous suspension of extremely fine solid particles of pure graphite dispersed in water. Lubricote-Z is supplied in paste-like consistency and should be diluted for most applications.

 

Lubricote-S series consists of a range of special-purpose colloidal suspensions of graphite in various organic liquids specifically made to meet special applications. The range of liquid media available includes the alcohols, acetone, poly isobutylene and glycols. These colloids are available with or without binders

Oxeeco’s Speciality maintenance products are born out of a need to overcome special problems being foaced in the field. Constant interaction between maintenance personnel in industry and Oxeeco’s R&D teams has resulted in an extensive range of products designed to meet the most exacting working conditions. The company was established in 1970 to manufacture high purity graphite, an activity in which it has maintained continuous leadership. The company soon diversified into manufacturing process and maintenance lubricants, speciality coatings and industrial cleaners. Oxeeco has one of the best equipped laboratories enabling most tests to be done in-house. Products undergo rigorous testing under stimulated conditions prior to extensive field trials. Constant improvement has enabled most products to be the market leaders in their category. Our high quality products and dedicated services have helped build relationships of mutual trust and confidence with a host of world class organizations, which have lasted over three decades. Our speciality maintenance products consists of a vast number of specially formulated lubricants, coatings and cleaners. Reducing maintenance by increasing component life cycles and eliminating breakdowns is a major contributor to productivity and profitability in industry today. Operating conditions combining high temperatures, harsh environmental conditions, corrosive atmospheres, extreme pressures and highspeeds pose over greater challenges for the development of lubricants and conatings. Using advanced techniques and materials Oxeeco has developed a range of products, which will meet the requirements of even the most severe operating conditions. Oxeeco maintains the highest standards of manufacturing to protest the environment and is constantly working towards ensuring that its products are environmentally fridnely and do not pose any health hazards to the users. Oxeeco’s products find use in all segments of industry, the transport sector, consisting of railway, shipping, aerospace and automotive applications, the energy sector, mining and metallurgical industries; food processing and pharmaceutical mfrs, agriculture, textiles, chemical industry, electrical and electronic industry.
