What are the excellent properties of boron nitride lubricants?

Hexagonal boron nitride is called white graphite. Because its structure is similar to white graphite, graphite is widely used in the industry to make various lubricants. Hexagonal boron nitride can also be used as a lubricant.

Compared with traditional carbon black and graphite, boron nitride lubricant has excellent lubricating performance and high temperature stability, which improves the use efficiency of the mold, prolongs the service life of the mold, improves the product qualification rate, and reduces the release agent. The dosage and increase economic benefits. In addition, the boron nitride lubricant has excellent environmental protection materials, which reduces environmental pollution during use, and can significantly improve the working environment of the factory and the cleanliness of the final product.

Boron nitride lubricants have the following characteristics: excellent high temperature resistance and oxidation stability, low friction coefficient, strong carrying capacity; no carbonization, no coking, no loss at high temperature, good high temperature lubricity; good water resistance, insulation and thermal conductivity Resistance, chemical resistance, non-corrosive metal; white, undyed, containing organic molybdenum additives, can enhance its lubrication and anti-wear properties.

Boron nitride lubricant is suitable for the lubrication of high-temperature or high-load, low-speed sliding parts, such as high-temperature bearings, bushings, bolts, fasteners, joints, sliding surfaces, etc., especially suitable for sintered parts such as buckles and thimble of injection molding machines , Sloping top and corner;

Boron nitride lubricants are suitable for the lubrication of high-temperature bearings and sliding parts such as heating furnaces, flame cutters, drying furnaces, and boilers at high temperatures. It is suitable for anti-wear and lubrication during assembly of various bolts and screws to prevent high temperature adhesion and sintering.

In addition to its own lubricating effect, boron nitride is relatively stable to almost all organic solvents and corrosive substances. Therefore, it is not necessary to consider that boron nitride will react with organic solvents or other components to affect the performance of the product. In addition, the white block formed by hot pressing and sintering of boron nitride powder is easy to process, which makes the production process simpler and more convenient.

Lubricants are only one aspect of the use of boron nitride. The heat resistance, corrosion resistance, and lubricity of boron nitride can be sprayed on graphite pads and containers for metal heat treatment and cemented carbide sintering with boron nitride powder. Prevent metal and alloy carburization, solve the problem of wetting of binder and graphite in alloy.

It can also be used as a mold release agent for glass and metal forming, orange paint, metal wire drawing lubricant and various pressure processing lubricants. Adding boron nitride to copper, aluminum, brass and other metal powders and sintering make self-lubricating powder metallurgy products, which can be used as oil-free bearings, sliding materials, contacts, etc. Boron nitride has many advantages in performance, so it can be used as lubricating materials, heat-resistant materials, corrosion-resistant materials, electrical materials and high-strength materials.

Hexagonal Boron Nitride (h-BN) Overview

Hexagonal Boron Nitride (h-BN) is an advanced synthetic ceramic that combines many useful thermal, electrical, physical and chemical properties in a unique material. The flake crystal structure is similar to graphite, but has higher oxidation resistance at 800°C. Boron nitride powder has high thermal conductivity, low friction coefficient, high dielectric constant and chemical inertness.

Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron nitride can withstand temperatures exceeding 2,000°C, and depending on the grade, its dielectric strength is close to 1000 volts/mil. Boron nitride is hot-pressed in the form of blanks, which can be easily processed into rods, rods, plates and even customized shapes.

Boron nitride is the simplest new polymer material. It has hexagonal and cubic crystal form. It is a product with high temperature resistance, corrosion resistance, high insulation and good lubricity. Its oxidation resistance temperature can reach 1000℃ and it has good lubricity. At high temperatures, it is a good high-temperature solid lubricant.

Hexagonal boron nitride (hBN), commonly known as "white graphite", is an artificial ceramic made by the reaction of boric acid or boron oxide with nitrogen at a temperature above 1600°C. Stability (oxidation resistance at 850°C) and lubricity.

Application of Hexagonal Boron Nitride BN Powder

Hexagonal boron nitride is white (clean appearance), non-toxic and non-conductive. It is an excellent substitute for other commonly used lubricants in metal processing (such as graphite, molybdenum disulfide, organic wax and oil). In most cases, boron nitride can greatly improve the efficiency of these applications.

Used as high temperature solid lubricant, extrusion anti-wear additive, ceramic composite material production additive;

Used for special electrolysis and resistance materials under high temperature conditions;

Aerospace insulation materials;

Used as a mold release agent for metal forming and a lubricant for metal drawing;

Used for molten metal crucible; radiator and high temperature insulator;

Used as a raw material for cosmetics.
