Spheroidizing Agent
Products Description
Spheroidizing agent is a chemical used in industrially processed materials that promotes the formation of spherical particles when materials (especially plastic polymers) deform and flow under high temperatures and pressures. The spheroidizing agent increases the molecular weight of the polymer by promoting the cross-linking of the molecular chains and makes it easy to handle and process. In addition, spheroidizing agents can also improve the heat resistance, weather resistance, mechanical strength and fluidity of polymers, thus making them more suitable for manufacturing a variety of products, such as pipes, cables, automotive parts, household appliances, etc. Common spheroidizing agents include diphenol peroxide, potassium aluminum sulfate, sodium aluminum sulfate, etc
Spheroidizing agent is usually used in metallurgy, construction, chemical industry, high energy physics and other fields. Its uses are as follows:
1. Spheroidized steel: spheroidizing agent can adjust the organizational structure of steel, improve the strength and toughness of steel, so as to increase its service life.
2. Spheroidized pig iron: spheroidizing agent can make the silicon element in pig iron into spherical, so as to improve its thermal stability, wear resistance and mechanical properties, so that it is more suitable for manufacturing high-precision mechanical parts.
3. Spheroidized steel casting: spheroidizing agent can improve the structure of the cast steel, reduce the porosity and cracks of the steel, improve the uniformity and stability of the structure, so as to improve its mechanical properties and toughness.
4. Spheroidized ceramic powder: spheroidizing agent can improve the fluidity and filling of ceramic powder, so as to make the prepared ceramic products more dense and uniform, increase its mechanical strength and thermal stability.
5. Spheroid ink: spheroidizing agent can improve the structure of graphite, increase its strength, hardness and wear resistance, so that it is more suitable for the manufacture of high-precision mechanical parts.
6. Other uses: spheroidizing agent can also be used to prepare high purity materials, additives, improve water quality and so on.
Spheroidizing agent is an additive added to a metal melt at high temperatures (usually between 1000 and 1300°C). It can refine the grains in the metal melt and make them become spherical or nearly spherical, so as to improve the plasticity and strength of the metal, and improve the casting and workability of the metal. Spheroidizing agent can also improve the fluidity of metal melt, reduce defects in castings and improve the quality of products.
The role of spheroidizing agent can be mainly summarized as follows:
1. Refining grains: spheroidizing agent can form rich gases at high temperature, which will form fine bubbles in the metal melt, thus promoting the formation and refining of grains.
2. Improve metal fluidity: spheroidizing agents can improve the fluidity of metal melts and reduce pores and other defects in metal liquids.
3. Improve the plasticity and strength: refining the grain can improve the plasticity and strength of the metal, so that it has more plasticity and ductility.
4. Improve casting performance: spheroidizing agent can improve the casting performance of metal, so as to reduce defects and defects in the casting, improve product quality.
In short, spheroidizing agent plays an important role in the production and processing of metal materials, which can improve the quality and performance of products.
