Factory inspection of graphite products

Graphite products are a kind of common special materials, widely used in electric power, metallurgy, chemical industry and other industries. In order to ensure that the quality and performance of graphite products meet the standard requirements, strict testing is required before leaving the factory. The following is the main content of graphite products factory testing:

Appearance inspection: Check the appearance of graphite products, including size, shape, surface finish, cracks, pores, scars and so on. Appearance inspection can preliminarily determine whether the quality of graphite products and processing technology meet the requirements.

Density detection: The density of graphite products is detected, usually by water drainage method or gas specific gravity method. The internal structure and material uniformity of graphite products can be understood through density detection.

Compressive strength testing: Compressive strength testing is performed on graphite products to assess their strength and deformation ability under pressure. The test results can check whether the mechanical properties of graphite products meet the requirements of the standard.

Electrical performance testing: the electrical conductivity and insulation of graphite products are tested to ensure that they meet the requirements of use. The test items include conductivity, resistivity, dielectric strength, dielectric loss, etc.

Chemical composition testing: The chemical composition of graphite products is tested to confirm the conformity of its raw materials and whether there are quality problems during processing. Detection items include element content, impurity content, etc.

The above is the main content of graphite products factory testing. Different types of graphite products may require different testing items, and the specific testing content should be determined according to product standards and needs.
