PP-B is a widely used chemical production raw material, mainly used in the manufacture of various plastic products. The following is the manufacturing method of PP-B:

1. raw materials to prepare

1. Propylene: The main raw material of PP-B is propylene, a simple olefin compound. Propylene can be obtained by petroleum cracking or natural gas processing.
2. Catalyst: In order to promote the production of polypropylene, it is necessary to use a catalyst. Common catalysts include titanium-based catalysts and magnesium-based catalysts.
3. Additives: According to the needs of product performance, some additives can be added, such as antioxidants, anti-ultraviolet agents, plasticizers, etc.

2. polymerization reaction

1. propylene, catalyst and auxiliary agent are added into the polymerization reactor according to a certain proportion.
2. At a certain temperature and pressure, the catalyst will promote the polymerization of propylene molecules to produce polypropylene.
3. Polymerization Various methods such as a solution polymerization method, a suspension polymerization method, or a gas phase polymerization method can be employed. Different polymerization methods will have a certain impact on the performance of the product.

3. Post-Treatment

1. Polymer Extrusion: Polypropylene produced by the polymerization reaction is extruded through an extruder to form strands or pellets.
2. Cooling and drying: The extruded polymer needs to be cooled and dried to remove moisture and volatiles.
3. Granulation and packaging: The dried polymer is granulated for storage and transportation. The product after granulation is packaged, that is, the finished PP-B.

The above is the basic manufacturing method of PP-B, and the specific production process and equipment will vary according to different manufacturers and product requirements. At the same time, in order to ensure the quality and performance of the product, it is necessary to strictly control the process parameters and material ratio of each link in the manufacturing process.

In short, PP-B, as an important raw material for chemical production, requires strict control of processes and materials in all aspects of the manufacturing process to ensure product quality and performance.
