The manufacturing method of PVC paste resin 

PVC paste resin is an important raw material for chemical production, widely used in plastic processing, coatings, adhesives and other fields. This article will introduce the manufacturing methods of PVC paste resin, including ingredients, mixing, gelatinization, drying, grinding, and packaging processes

1、 The main raw material for PVC paste resin is polyvinyl chloride resin, and auxiliary materials such as stabilizers, plasticizers, and fillers need to be added. When adding ingredients, various raw materials need to be added to the ingredient tank in a certain proportion according to the requirements of the product

2、 After mixing the ingredients, it is necessary to thoroughly mix various raw materials to ensure the stability of product quality. The mixing process generally uses equipment such as high-speed stirring or internal mixer to mix the raw materials evenly

3、 The material after gelatinization 

mixing needs to enter the gelatinization equipment for gelatinization. Gelatinization is the process of heating and melting the polyvinyl chloride resin in the ingredient, while adding auxiliary materials such as stabilizers, to form a paste with a certain viscosity and fluidity. The temperature and pressure of the gelatinization equipment need to be controlled within a certain range to ensure product quality and yield

4、 After drying, the paste needs to be dried to remove moisture and volatile substances. Generally, fluidized bed dryer or spray dryer and other equipment are used to dry the paste to a certain humidity before discharging

5、 Grinding 

The dried material needs to be ground to obtain the desired fineness of PVC paste resin. Grinding is generally carried out using equipment such as ball mills and sand mills, which grind the material to a certain fineness before discharging it

6、 Packaging: The PVC paste resin after grinding needs to be packaged for storage and transportation. Packaging generally uses plastic bags or paper bags and other packaging materials. After the product is packaged, it can be stored or shipped

The above is the basic manufacturing method of PVC paste resin, and the specific production process needs to be adjusted and optimized according to the requirements of the product and the actual situation of the equipment. At the same time, in order to ensure the quality and output of products, it is necessary to strictly control the process parameters and quality indicators of each link in the production process

In short, the manufacturing method of PVC paste resin is a complex process that requires close coordination and strict control of various links. Only by mastering the correct manufacturing methods can high-quality PVC paste resin products be produced and contribute to the development of the chemical production field.
