Ningheda Graphite Technical Characteristic:

What is Graphite Plate?

Graphite plate(graphite boat) adopts high-quality graphite material, adding organic compound with strong acid resistance.

It is refined by high-pressure forming, vacuum impregnation, and high-temperature heat treatment. It has extraordinary acid and temperature resistance.

It is an ideal lining material for phosphoric acid reaction tanks and phosphoric acid storage tanks in the chemical industry.

The product has the characteristics of wear resistance, temperature resistance, pressure resistance, corrosion resistance, creep resistance, oil-free self-lubrication, small expansion coefficient, and superior sealing performance.

Advantages of Ningheda graphite raw material

1. The processing materials are ultrafine granule structure, high purity and graphite with high graphitization degree.
2. High hardness, good anti-oxidation performance and high machining accuracy
3. Good conductivity, high resistivity, sufficient mechanical strength
4. Small porosity and dense structure.
5. Excellent thermal shock resistance, conductive and thermal conductivity.
6. High temperature resistance, corrosion resistance, acid and alkali resistance, good wear resistance.
7. Surface can be treated with anti-oxidation.

Advantages of Graphite plate machined by Ningheda

1. Excellent corrosion resistance
The product adopts high-quality graphite material and adds an organic compound with strong acid resistance, which effectively reduces the porosity of the product and increases the volume density of the product. Therefore, the product has excellent corrosion resistance and strong wear resistance.
2. Stable performance and strong durability
The product uses high-strength organic glue as a binder and introduces high-tech additives at the same time, so the product has high strength, good wear resistance, and extremely stable structure. The product structure does not change with temperature changes.
3. Accurate dimensions
Using compression molding, the product has good molding quality and precise dimensions, and can produce special products according to user requirements, which can fully meet the requirements of construction and masonry technology.

Main applications of Graphite Plate

Graphite plate (graphite boat) are widely used in powder metallurgy and cemented carbide sintering. It includes a number of W-shaped bidirectional chute with two opposite groove surfaces and bottom supporting protrusions, a bottom surface, an upper end surface, an inner side surface, an outer side surface and a stop opposite to the upper end surface. The two opposite groove surfaces are respectively designed with At least one exhaust through groove, the intersection of the bottom supporting protrusion and the two opposite groove surfaces are respectively designed with an edge protection groove. The bottom surface is designed with a through groove parallel to the W-shaped two-way chute and the cross-sectional shape is approximately Λ-shaped at the lower part of the protrusion formed by any two adjacent W-shaped two-way chute grooves. The utility model makes the hard alloy long thin sheet products uniformly degummed during the hydrogen degumming and vacuum sintering process, avoids product warpage and deformation, and has a large product load and few consumables.
The graphite plate of Jiangxi Ningheda New Material Co., Ltd. has high processing precision, excellent material, high temperature resistance, corrosion resistance and long service life.
