China coal tar 4

This comprehensive guide explores China's production and applications of Coal Tar Pitch 4, addressing its properties, uses, and market dynamics. Learn about the different grades available, quality control measures, and its role in various industries. We'll also delve into safety considerations and explore future trends in this important material.

What is Coal Tar Pitch 4?

China coal tar pitch 4 is a byproduct of coal tar distillation, a black, viscous, and thermoplastic material. Its composition varies depending on the coal source and the distillation process. Key characteristics include its high carbon content, excellent binding properties, and resistance to certain chemicals. Understanding the nuances of its properties is crucial for selecting the appropriate grade for specific applications.

Grades and Specifications of China Coal Tar Pitch 4

Several grades of China coal tar pitch 4 exist, each possessing slightly different properties and suited for varying industrial needs. These grades are often defined by parameters such as softening point, quinoline insoluble content (QI), and viscosity. Precise specifications are crucial for ensuring consistent product quality and performance in manufacturing processes. Suppliers often provide detailed datasheets outlining these specifications.

Softening Point

The softening point is a key indicator of the pitch's viscosity and its suitability for different applications. A higher softening point generally indicates a harder, more brittle pitch, while a lower softening point suggests a more fluid material. The required softening point varies considerably depending on its intended use.

Quinoline Insoluble (QI) Content

The QI content signifies the amount of insoluble material in the pitch after treatment with quinoline, a solvent. A higher QI content often implies a greater concentration of high-molecular-weight components. This influences the pitch's strength, durability, and overall performance characteristics in applications such as carbon electrode manufacturing.
