About JinhuiEstablished in 1999, the company is located in Pingdu City, Qingdao, Shandong Province, a prime production area for high-quality flake graphite in China.
Characteristics and applications of high-purity graphite
High-purity graphite flakes have complete crystallization, are thin and tough, possess excellent physical and chemical properties, and exhibit good thermal conductivity and temperature resistance. They are widely used in industrial fields such as metallurgy, chemical engineering, aerospace, electronics, machinery, and nuclear energy. Especially large-sized, high-quality high-purity graphite, as an alternative material, has broad application space and wide application prospects in high-tech and new technology fields.

Common preparation methods for expandable graphite
Chemical intercalation method: The initial raw material used for preparation is high-carbon flaky graphite, and other chemical reagents such as concentrated sulfuric acid (98% or more), hydrogen peroxide (28% or more), and potassium permanganate are all industrial-grade reagents. The general preparation steps are as follows: At an appropriate temperature, hydrogen peroxide solutions of different ratios, natural flaky graphite, and concentrated sulfuric acid are added in different procedures, reacted for a certain period under continuous stirring, then water-washed to neutral, centrifuged, and vacuum-dried at 60 ℃ after dehydration.

Applications of Expandable Graphite (1)
Expandable graphite as a battery material utilizes the free energy change of the intercalation reaction of expandable graphite to convert into electrical energy. Typically, expandable graphite is used as the cathode and lithium as the anode, or expandable graphite compounded with silver oxide as the cathode and zinc as the anode. Fluorinated graphite, graphitic acid, and expandable graphite containing metal halides such as AuCl3 and TiF4 have been applied in batteries.

Applications of Expandable Graphite (2)
Due to the expansibility and high-temperature resistance of expandable graphite, it has become an excellent sealing material and is widely used in fireproof sealing strips.

Applications of Expandable Graphite (Part 3)
Fire wraps, moldable firestop sealants, fire collars: Because expandable graphite has anti-destruction capabilities at high temperatures and a high expansion rate, it can be used as an effective intumescent flame retardant material in fire wraps, moldable firestop sealants, and fire collars. Used for firestopping in buildings (e.g., sealing openings where building pipes, cables, wires, gas, natural gas pipes, and air ducts pass through).

Difference between flake graphite and expandable graphite
Flake graphite is a type of natural graphite. After mining and purification, it generally appears in a fish-scale shape, hence the name flake graphite. Expandable graphite is flake graphite that has undergone acid washing and intercalation treatment, expanding about 300 times compared to its original graphite state. It can be used as raw material for coiled materials and flexible graphite. Below, let me introduce you to the differences between flake graphite and expandable graphite in detail:

What factors affect the quality of flake graphite?
The quality of flake graphite determines the product quality of processed flake graphite powder. Flake graphite resources are phanerocrystalline natural graphite, formed by the metamorphism of carbonaceous rocks under long-term geological action. Flake graphite crystals are flaky. The size of flake graphite crystals and the amount of fixed carbon content are key factors affecting the quality of flake graphite. Below, we'll take you through it:
