The manufacturing method of recycled ABS/PS 

1. Introduction 

With the rapid development of the plastic industry, the quantity of waste plastics is also increasing year by year. The recycling and utilization of waste plastics has become a global issue. Among them, regenerated ABS/PS, as an important raw material for chemical production, has high utilization value. This article will introduce a manufacturing method for regenerating ABS/PS

2、 Materials and Methods 

1 Materials: Waste ABS/PS plastics, catalysts, stabilizers, antioxidants, etc

2. Equipment: Twin screw extruder, pelletizer, oven, mixer, etc

3. Manufacturing method 

(1) Crushing and cleaning: Crush the waste ABS/PS plastic to obtain fragments of a certain size, and then clean to remove oil stains and other impurities

(2) Drying: Dry the cleaned fragments to reduce their moisture content to a certain range

(3) Ingredients: Add dried fragments, catalysts, stabilizers, antioxidants, etc. to the mixer in a certain proportion for thorough mixing

(4) Extrusion granulation: The mixture of ingredients is added to a twin-screw extruder for high-temperature melting extrusion, and then cut into a certain length of pellets through a pelletizer

(5) Post treatment: The extruded pellets are subjected to post-treatment such as cooling, screening, and packaging to obtain regenerated ABS/PS products

3、 Results and Discussion 

1 After the above process treatment, the regenerated ABS/PS product obtained has good physical and mechanical properties, which can meet the requirements of most chemical production

2. Process optimization 

In order to improve the performance and yield of the product, further optimization of the process can be carried out, such as adjusting the ingredient ratio, increasing the extrusion temperature, changing the cutting length, etc

3. Environmental Protection and Sustainability 

The manufacturing process of recycled ABS/PS meets the requirements of environmental protection and sustainability, which can not only reduce the impact of waste plastics on the environment, but also improve the utilization rate of resources

4、 Conclusion: This article introduces a manufacturing method for regenerated ABS/PS, which has the advantages of simple process, convenient operation, and excellent product performance. It can provide an important source of regenerated raw materials for chemical production. Meanwhile, this method also meets the requirements of environmental protection and sustainability, and has good prospects for promotion and application.
