Abstract 

This article provides a detailed introduction to the research and practice of PE hollow manufacturing method in the field of chemical production raw materials. By analyzing the characteristics of PE materials, this paper elaborates on the production process and equipment selection of PE hollow products, and explores possible problems and solutions that may arise during the manufacturing process. This study aims to provide theoretical support and practical guidance for the production of PE hollow products

1、 Introduction: With the rapid development of the chemical industry, polyethylene (PE), as a common plastic material, has been widely used in various fields. PE hollow products have become the preferred material in many industries due to their lightweight, durability, and low price characteristics. This article will delve into the manufacturing methods of PE hollow products to improve production efficiency, reduce costs, and create greater economic benefits for enterprises

2、 Characteristics of PE Material 

Polyethylene (PE) is a thermoplastic resin with good low-temperature resistance, chemical stability, and excellent electrical insulation performance. Meanwhile, PE has a lower density, is easy to process and shape, and is relatively inexpensive. These characteristics make PE have broad application prospects in the field of chemical raw materials

3、 Production process of PE hollow products 

1 Ingredients and Mixing 

Select appropriate PE resin, additives, and additives for ingredients according to product requirements. Add the ingredients into the internal mixer or open mixer for mixing, ensuring uniform mixing of the materials

2. Extrusion molding: The mixed material is added to the extruder, and through the rotation and heating of the screw, the material is melted and plasticized, forming a continuous and stable tubular extrusion

3. Blow molding 

introduces the extruded tubular extrusion into the blow molding mold, expands it by compressing air, and adheres closely to the inner wall of the mold to form the desired hollow product shape

4. Cooling and shaping: Cool the blown molded product through a cooling fan or water cooling system to quickly solidify and shape it

4、 Equipment selection and operation skills are of great significance for improving production efficiency and reducing costs in the production process of PE hollow products. Here are some suggestions: 

1 Extruder: Select an extruder with high torque, high precision, and good stability to meet different production needs

2. Blow molding mold: Select a suitable mold according to product requirements to ensure dimensional accuracy and surface smoothness of the product

3. Cooling system: Choose an efficient cooling system to improve production efficiency

4. Operation skills: Master appropriate parameters such as temperature, pressure, and speed to ensure stable production process and improve product quality

5、 Manufacturing process problems and solutions: In the manufacturing process of PE hollow products, there may be some problems, such as uneven surface, dimensional deviation, material waste, etc. To address these issues, the following measures can be taken: 

1 Adjust the formula and mixing process to improve material uniformity

2. Optimize extrusion and blow molding parameters to improve product dimensional accuracy and surface quality

3. Strengthen equipment maintenance and upkeep, reduce failure rates, and improve production efficiency

4. Train operators to improve their skills and reduce material waste during the production process

6、 Conclusion: Through exploring the manufacturing methods of PE hollow products, we have learned about the issues that need to be noted in the production process and corresponding solutions. By selecting appropriate equipment and mastering operational skills, production efficiency can be further improved, costs can be reduced, and greater economic benefits can be created for enterprises. Meanwhile, continuous research and improvement of manufacturing methods can help promote technological progress and development in the field of chemical raw materials production.
