QDLW Graphite Material Technology Company is a modern enterprise engaged in graphite purification and high-end carbon materials, a subsidiary of China BA.
The company has invested 500 million yuan in the construction of 150,000 tons of graphite purification and high-end carbon materials.
Products
Graphite heat dissipation material
The product is matched with a special particle size ratio, goes through a purification process, and then undergoes high temperature to remove internal volatile acid, and finally the product is made.
The resulting product has a thermal conductivity of 6.08, which is twice as high as that of similar foreign products.
High purity expandable graphite
Use heavy metal-free hydrogen peroxide as a strong oxidant for processing, use high-purity sulfuric acid as an intercalant, wash with water and then chemically purify it to make high-purity expandable graphite with a purity of 99.8-99.95% or more, which can be used for high-end thermal conductive graphite paper , Fireproof materials and sealing materials as well as absorbent materials.
Natural graphite recarburizer
The recarburizer produced by QDLW is different from the granular recarburizer on the market. The raw material is made of natural graphite or artificial graphite, which is kneaded, extruded, and dried to obtain a finished product with low sulfur content. The advantage is that the physical state maintains high density, it is easy to mix molten steel, the fusion rate is significantly increased, and the carbon adsorption rate is increased.
Graphite powder for lead-acid batteries
Different amounts of graphite are added to the positive electrode paste of the lead-acid battery, which is processed into a positive electrode plate after industrial processing. After high-purity graphite is treated, the content of trace elements is extremely low, and the addition of graphite powder can improve the wettability of sulfuric acid, improve the fluidity of sulfuric acid, and prevent sulfation. Finally, the positive electrode active material can better participate in the charge and discharge reaction and improve its utilization.
Porous graphite for high-end alkaline zinc-manganese battery
Main features: Use metal-free high-purity expanded graphite as raw material, after 1000 degrees high temperature treatment, after jet pulverization, it can reach the product index at one time. Product advantages: small specific gravity, high specific surface area, low content of harmful trace elements (Fe, Cu, Mo, Pb), ranking the domestic advanced level of similar products. The main supply groups are Duracell and Nanfu series.
Alkaline zinc manganese battery powder
Main features: low trace elements (Fe, Cu, Mo), low product specific gravity, excellent electrical performance, and low gas outgassing of battery powder. The technical performance of the product is stable, and it is at the advanced level of similar domestic products. It can completely replace imported graphite powder and can greatly improve the use and storage life of the battery.
High purity flake graphite
High-quality flake graphite is used for purification by chemical purification method. The finished product has complete flake crystals, stable physical and chemical properties, good temperature resistance, lubricity, conductivity, thermal shock resistance, corrosion resistance and other characteristics.
Small particles of high purity spherical graphite, large particles of high purity spherical graphite
Using high-quality natural flake graphite as raw material, it is produced through the process of (crushing-shaping-grading-chemical purification-pure water washing-drying-demagnetization-sieving-demagnetization-packaging). The product has good stability. The sphericity is good, the impurity control measures are good, and the finished product can achieve high capacity and good cycle performance.
