Graphite :

 

Introduction

Natural, its phosphorus, shaped like a fish is a hexagonal system, a layered structure, has good resistance to high temperature, conductive, thermal conductivity, lubrication, plastic, and acid and alkali resistance and other properties. Flake graphite is a kind of layer structure of natural solid lubricant, rich resources and cheap price. Flake graphite crystallization is complete, thin and toughness, good physical and chemical performance, good thermal conductivity, electrical conductivity and thermal shock resistance, corrosion resistance, etc.

According to the carbon content of classification, such as C %, 99.9% high purity graphite; C % < 94% and 99% for high carbon graphite; 80% C % < 94% carbon graphite; 94% C % < 80% for low carbon graphite. Refractory of flake graphite is widely used in metallurgical industry, light industry, the pencil lead electrodes, battery technology, chemical industrial lubrication sealing materials, etc. As the function of the coating packing is mainly used in anticorrosive coatings, fire retardant coatings and conductive coatings.

Flake graphite is widely used in metallurgical industry of high-grade refractory materials and coatings. Such as magnesia carbon brick, crucible, etc. Military industrial fire engineering materials stabilizer, smelting industrial desulfurization of pencil lead growth agent, light industry, carbon brush of electrical industry, battery industry of electrode catalyst, chemical fertilizer industry, etc.

Flake graphite after further processing, and can produce graphite, used for lubricants, release agent, wire drawing, conductive coatings, etc. Can also production of expanded graphite and flexible graphite products raw materials, such as flexible graphite seals and flexible graphite composite material products, etc.

According to the particle size classification: when particle size less than w38 micro powder of graphite.

Flake graphite as coating functional filler used in anticorrosive coatings, fire retardant coatings and conductive coatings.

Usage

- as mould release lubricant in the production of catalyst of in chemical fertilzer industry.

- as basis material of high-temperature or corrosive resistant lubricants.

- as mould release agent in powder metallurgy or raw material in metal alloy.

- as packings or catalysts of rubber,plastics and varieties of composite materials.
