In the field of raw materials for chemical production, additives play a vital role. They can change the properties of raw materials, improve production efficiency, give products specific properties, or help the process. Below we will discuss in detail the nature and use of additives.

1. the nature of additives

1. chemical stability: additives must have a certain chemical stability, in order to maintain its properties in the production process, but also with the main material and other additives good compatibility.
2. Thermal stability: Many chemical production processes involve high temperature environments, so additives need to have thermal stability to ensure that they do not decompose or deteriorate under high temperature conditions.
3. Compatibility: Additives need to have good compatibility with other raw materials and additives without adverse reactions or precipitation.
4. Functionality: Additives need to have specific functionality to meet the specific needs of the production process, such as catalysis, oxidation resistance, corrosion resistance, etc.

2. additives use

1. catalyst: catalyst is one of the commonly used additives in the production process of chemical products. It can accelerate the speed of chemical reactions and improve production efficiency. Common catalysts include acid-base catalysts, redox catalysts, etc.
2. Antioxidants: Antioxidants are additives used to prevent oxidation of chemicals during production, storage and use. It can extend the service life of the product and keep the performance of the product stable.
3. Anticorrosion agent: Anticorrosion agent is used to prevent equipment, pipelines, etc. from being corroded in the production process. It can reduce equipment maintenance and replacement costs and improve production efficiency.
4. Surfactants: Surfactants can change the surface tension of a liquid, making it easier to wet, emulsify, or disperse. It is often used to improve the dispersion, stability and fluidity of products in the production of chemicals.
5. Plasticizers: Plasticizers can change the properties of polymer materials to make them more flexible, malleable and processable. It is often used in the production of plastics, rubber and other polymer materials.

In general, additives play a vital role in the field of raw materials for chemical production. It can optimize the production process, improve production efficiency, and give products specific properties.

3. auxiliaries selection and use of

1. according to the production needs of the choice of additives: different chemical production process requires different types of additives. When selecting additives, it is necessary to select suitable additives according to production requirements to ensure their functionality.
2. Pay attention to the compatibility of additives: When using additives, you need to pay attention to its compatibility with other raw materials and additives to avoid adverse reactions or precipitation.
3. Control the use of additives: the use of additives need to be controlled within a certain range, too much or too little use may affect the performance of the product and the production process.
4. Pay attention to the storage and transportation of auxiliaries: The storage and transportation of auxiliaries also require special attention to ensure the stability and safety of their properties.

In summary, additives play a vital role in the field of raw materials for chemical production. They can optimize the production process, improve production efficiency, and give products specific properties. When selecting and using additives, it is necessary to comprehensively consider factors such as production demand, compatibility, usage, storage and transportation to ensure that additives can maximize their role and improve the economic and social benefits of chemical production.
