Standard formulation background and technical evolution analysis

Since its first release in 1997, this standard has been revised several times to reflect the development of molybdenum disulfide production and application technology. Compared with the 2009 version, the main changes include:

Scope of application adjustment:The product's usage scenarios are more clearly defined.
Chemical composition requirements:The main content and impurity indicators of each brand have been optimized to meet the needs of different industries.
Particle size control:Introduce laser particle size analysis to improve the consistency of product performance.
Inspection rules:Added accompanying document requirements to strengthen product quality traceability.

Implementation suggestions

To ensure the effective implementation of the standard, the following measures are recommended:

Internal training:Provide detailed standard interpretation and operating specification training to production and technical personnel.
Equipment upgrade:Update inspection equipment, especially key instruments such as particle size analyzers.
Quality monitoring:Establish a regular sampling inspection system to ensure that products meet standard requirements.
Supply chain management:Consult with suppliers to extend standard requirements to upstream material procurement links.
