Read： 703 Time：18months ago Source：Transform the World with Simplicity

Rubber particles and rubber particles play an important role in the production of chemical products. They are the key raw materials for many industrial products and daily necessities. This article will introduce the manufacturing method of rubber particles and rubber particles in detail, including the steps of raw material preparation, mixing, extrusion, cooling, pelletizing and post-processing.

1. Raw Material Preparation

The first step in manufacturing rubber pellets and crumbs is to prepare raw materials. The raw materials usually used are natural rubber or synthetic rubber, and other additives, such as fillers, vulcanizing agents, accelerators, anti-aging agents, etc. The quality and ratio of these raw materials directly affect the performance and quality of the final product.

2. mixing

mixing is the raw materials in accordance with a certain ratio and order into the mixer or open mill, through mechanical action to make all kinds of raw materials evenly mixed process. During the mixing process, it is necessary to pay attention to the control of parameters such as temperature, time and pressure to ensure the quality of the mixture.

3. extrusion

extrusion is the process of forming the mixture into a strip or tube of a certain shape and size through the extruder head. During the extrusion process, attention should be paid to the control of extrusion speed, temperature and pressure to ensure the quality and dimensional stability of the extrudate.

4. Cooling

The extruded rubber strip or tube needs to be cooled quickly to prevent deformation or other quality problems. Cooling is usually carried out by means of water bath or air cooling.

5. pelletizing

The cooled rubber strip or tube needs to be cut according to a certain length to form rubber particles or rubber particles of a certain size. During the pelletizing process, it is necessary to pay attention to the control of parameters such as the sharpness of the tool and the cutting speed to ensure the quality and efficiency of the pelletizing.

6. post-processing

The finished rubber particles or colloidal particles need to be post-processed, including screening, dust removal, drying and other steps to ensure product quality and storage stability.

In short, the manufacturing method of rubber particles and rubber particles needs to go through multiple steps and links to ensure the quality and performance of the final product. At the same time, it is necessary to pay attention to safety, environmental protection and energy saving issues in the production process to promote the sustainable development of the chemical production field.
