The plastics processing industry is a highly comprehensive technology-based industry. It involves polymer chemistry, polymer physics, interface theory, plastic machinery, plastic processing molds, formula design principles and process control. The extrusion theory mainly studies the movement and changing laws of plastics in the extruder. The relationship between the three physical states of the polymer in different temperature ranges of the plastic material in the extruder under the action of a certain external force, and the screw structure, plastic properties, and processing conditions......

Railway construction plays a vital role in a country's economic development. China's current railway transportation network is still relatively developed. In the process of railway construction, we need not only steel materials, but also some plastic materials. When it comes to plastic materials, we have to mention the machines for processing plastic materials. In fact, the best plastic processing machine is the granulator......

The product quality will be higher after granulation for the following reasons:1. The particles and granular particles are uniform, the crushed particles are not uniform, the material is unstable, the gap size and melt density are different, and some will increase the difficulty of adjustment;2. From the perspective of material impurities, when the granulated material is granulated, it is difficult for some impurities to enter the interior of the material after filtration, which is relatively clean and difficult to pulverize the material;3. From the perspective of color, the color after granulation is relatively uniform......

What are the differences between single-screw and twin-screw granulators? The following Xihua mechanical engineers will explain the difference between single-screw and twin-screw granulators. The details are as follows:Let's take a look at the difference between single screw granulator and twin screw granulator from the working principle Single screw granulator: The material passes through the feeding port, and under the action of the rotating screw, It is kneaded into a ball and rolled along the screw groove. Due to the shearing......

Facing all kinds of granulator equipment on the market, it is already dazzling. How to make their own granulator stand out in the market is a headache for every manufacturer, and how to correctly choose the granulator equipment is a troublesome thing for every customer. This article will introduce to you how to correctly choose granulator equipment, and how to get out of the misunderstanding of purchasing granulator equipment......

I. Roller The drum is the main working part of the open mill. It is the part that directly participates in the completion of the rubber mixing work, and has a relatively large impact on the function of the open mill. Therefore, great attention should be paid to the design, manufacture and use of the roller.1. Material and technical requirements The basic requirements for the roll of the open mill are......
