Product features
1.High temperature resistance:
This is one of its most outstanding features. Generally speaking, ordinary graphite plates can be used in environments below 1200 degrees without any problem, while high-quality high-temperature graphite plates can withstand temperatures above 3000 degrees in protective environments such as vacuum and inert gas. Its structure is an atomic crystal. The carbon atoms are connected by covalent single bonds to form a smooth regular hexagonal porous structure. The bond energy of the covalent single bonds is very high and requires higher energy to destroy, so it can withstand high temperatures.
2.Good chemical stability:
Graphite plates have good chemical stability at room temperature and are not corroded by strong acids, strong alkali and solvents.
3.Excellent electrical and thermal conductivity:
Graphite plates have good electrical and thermal conductivity and can be used in situations where electrical or thermal conductivity is required.
4.Low thermal expansion coefficient:
When the temperature changes, the size of the high-temperature resistant graphite plate changes less, which ensures its accuracy and stability during use.
5.Self-lubricating:
Graphite plates have self-lubricating properties, which reduces friction and wear and reduces maintenance costs.
6.Ease of processing:
It can be easily made into various shapes and sizes to meet different usage needs.

Quality inspection and packaging
1. Appearance inspection
Density testing:
By measuring the mass and volume of the graphite plate, calculate its density to ensure compliance with product standards.
Strength testing:
Use appropriate testing methods, such as compression test, bending test, etc., to detect the mechanical strength of the graphite plate.
Conductive performance testing:
Use a conductive tester to measure the resistivity of the graphite plate to determine whether its conductive performance meets the requirements.
Corrosion resistance test:
According to the use environment of the graphite plate, conduct corresponding corrosion resistance tests to evaluate its corrosion resistance under specific conditions.
2.Appearance inspection
Observe whether the surface of the graphite plate is flat and smooth, without obvious cracks, pits, bulges and other defects.
Check whether the edges are neat and free of burrs, chipping, etc.
3.Dimensions
Use measuring tools with appropriate accuracy to measure the length, width, thickness and other dimensions of the graphite plate to ensure that it meets the tolerance range required by the design.
For graphite plates with special shape requirements, it is also necessary to check whether the shape and size are accurate.
4.Packaging
For smaller size graphite plates, multi-layer packaging can be used, with foam paper or bubble wrap between each layer to prevent collision and friction.
Larger-sized graphite plates can be packed in wooden pallets. The graphite plates are fixed on the pallet and then wrapped with plastic film or stretch film.
FAQ
What is the high temperature resistance of graphite products?
Graphite has excellent high temperature resistance. Ordinary graphite products can work stably at high temperatures of around 2000°C, while some special high-purity graphite products can even withstand higher temperatures.
What is the chemical stability of graphite?
Graphite has good stability to most chemicals. At normal temperature, it does not react with acids, alkalis, salts, etc. However, at high temperatures, oxidation reactions may occur when in contact with strong oxidants.
Does graphite have good thermal conductivity?
Graphite has very good thermal conductivity and is a good thermal conductive material. It has a higher thermal conductivity than many metals, allowing it to transfer heat quickly and evenly.
How to judge the quality of graphite products?
The quality of graphite products can be judged from the following aspects: first, look at the appearance, the surface should be smooth, without cracks, and without impurities; secondly, check the density, graphite products with high density usually have better quality; you can also test their electrical conductivity, thermal conductivity, etc. indicators to assess quality.
