Rubber particles and rubber particles have important properties and uses in the field of chemical production raw materials. This paper will detail the properties, production methods, uses and development prospects of rubber particles and colloidal particles. The nature and use of

1. rubber particles

rubber particles are small particles made of waste rubber products through crushing, grinding and other processes. Rubber particles have the following properties:

1. Good elasticity: Rubber particles are mainly composed of elastomers, which have good elastic properties and can absorb and release energy.

2. Wear resistance: Rubber particles have good wear resistance and can be used in high wear environments.

3. Oil resistance, acid and alkali resistance: rubber particles have good oil resistance, acid and alkali resistance, and can be used in harsh chemical environments.

rubber particles are widely used in the field of chemical production raw materials, mainly including the following aspects:

1. reclaimed rubber production: rubber particles can be used as reclaimed rubber production raw materials, through certain process processing, made of various types of reclaimed rubber, used in the production of rubber products.

2. Plastic modification: Rubber particles can be added to plastics to improve their toughness, impact resistance and processing performance.

3. Pavement: Rubber particles can be used to lay sports fields, runways, etc., to improve the elasticity and anti-skid performance of the pavement.

2. the nature and use of colloidal particles

colloidal particles refers to colloidal dispersions in the particle diameter between 1-100nm small particles. Colloidal particles have the following properties:

1. small size effect: the size of colloidal particles is very small, with small size effect, showing some special physical and chemical properties.

2. Surface activity: Colloidal particles have high surface activity and can be adsorbed on the interface to reduce surface tension.

colloidal particles are also widely used in the field of chemical production raw materials, mainly including the following aspects:

1. catalyst carrier: colloidal particles can be used as a catalyst carrier to improve the activity and selectivity of the catalyst.

2. medical field: colloidal particles can be used as drug carriers to deliver drugs to the diseased parts and improve the efficacy of drugs.

3. food additives: some colloidal particles can be used as food additives to improve the taste and texture of food. The production method of

3. rubber particles and rubber particles
the production method of
rubber particles mainly includes physical method and chemical method. Physical method is mainly through mechanical crushing, grinding and other processes to process waste rubber products into small particles. The chemical law is to decompose waste rubber products into smaller molecules through chemical reactions, and then further process them into rubber particles. The production method of

colloidal particles is mainly prepared by chemical synthesis, physical dispersion and other methods. Among them, the chemical synthesis method can produce colloidal particles with better uniformity, but the production cost is higher; the physical dispersion law is to disperse macromolecular substances into small granular substances through mechanical stirring, ultrasonic waves, etc.

4. development prospects

With the increasing emphasis on environmental protection and sustainable development, rubber particles and rubber particles as an important part of chemical production raw materials, its development prospects are very broad. In the future, with the continuous advancement of technology and the continuous expansion of application fields, the application of rubber particles and rubber particles in the field of chemical production raw materials will be more extensive, and the market demand will further increase. At the same time, as people's requirements for product quality and performance continue to increase, higher requirements will be placed on the performance and quality of rubber particles and rubber particles, and technological research and development and product innovation need to be continuously strengthened to meet market demand.
