EPS Pre-expander series

EPS Pre-expander Machine Production Process

 

After the EPS Pre-expander Machine, the beads retain a certain amount of foaming agent and water vapor. When they are discharged from the machine, they condense into a liquid, and the liquid foaming agent is dissolved in the polystyrene, making the pressure in the bubbles very high Decrease quickly, negative pressure (partial vacuum) appears in the bubble, and the beads are very soft and easily deformed. 

 

Therefore, when air is sent, try not to make the wind pressure too large. The Pre-Expander EPS Foaming Machine inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. 

 

When Pre-Expander EPS Foaming Machine sparking, the transmission speed should not exceed 8m/s to avoid damage to the beads. The beads of the EPS Pre-expander machine are all moist. After being discharged from the EPS Pre-expander machine, they absorb air and suddenly encounter cold, which causes the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells. The pellets must be placed for a period of time after pre-expansion. On the one hand, they are dried, and on the other hand, they are allowed to infiltrate air to eliminate negative pressure, so that the internal pressure and external pressure in the cells can be balanced, so as to prevent the cells from collapsing and make the beads elastic.

 

The process of drying, cooling, and stabilizing the cell pressure of the Pre-Expander EPS Foaming Machine that are just out of the EPS Pre-expander machine for a certain period of time is called maturation. Maturation improves the further expansion of the pre-expanded beads during the molding process, the sintering between beads and the elasticity of the beads, which is beneficial to improve the quality of EPS products.

 

During the curing process, the beads are cooled by air, and the foaming agent and water vapor in the pores of the cells are condensed into liquid, so that negative pressure is formed in the cells. At this time, the air penetrates into the cell through the cell membrane to balance the pressure in the cell with the external pressure, which will make the pre-expanded beads elastic.

 

The maturation can be divided into two methods: natural maturation and pressure maturation. Under cool, dry, and ventilated conditions, allowing natural aeration is called natural maturation. Adding gas (air, nitrogen) to the pre-expanded beads after natural maturation in a sealed container to make them have a certain pressure and inflate it, which is called pressurized maturation.

EPS Continuous Pre-expander machine

 

The EPS Continuous Pre-expander machine is a new and improved way to expand polystyrene (PS) products. It uses a continuous stream of pressurized hot air to evenly expand the product, making it more durable and less likely to tear. The machine also has a high expansion ratio, which means that it can produce larger pieces of PS than other pre-expanders.

 

EPS batch pre-expander

 

The EPS batch pre-expanderis a machine that helps to speed up the production of ethanol by breaking down the starch into simple sugars. This allows for the creation of more ethanol in a shorter amount of time, which can help to save on costs.

 

EPS batch pre-expander is a new type of pre-expander that can be applied to EPS production lines. It has the ability to reduce the amount of material needed for a given output, leading to lower production costs. This technology is especially useful in cases where the final product must meet certain specifications, such as low weight or low volume.

 

Use of The EPS Pre-Expander machine

 

The EPS Pre-Expander machine is a versatile and efficient tool that can be used in a variety of different industries. The machine is able to quickly and easily expand EPS foam, which is important for many applications. This includes creating insulation for buildings, packaging material, and other products.

 

 

 

What are the characteristics of the EPS machine?

 

For the fields that need to use EPS machines, if you have not purchased such equipment before, you will definitely worry that the equipment you purchased cannot meet the requirements, and there are even many quality problems that cannot be ignored. How to do it to have better results? The following time will not only mention the characteristics of the equipment, but also help people find more reliable manufacturers.

 

1, the larger compression ratio of the EPS machine

 

Friends who lack experience in use must not know what product features the EPS machine relies on in order to be recognized and loved by the majority of customers. Constantly grasping more information about the equipment, you can know that the equipment of professional manufacturers not only has stable performance, but also can exert a greater compression ratio.

When we know that the performance of the polystyrene machine is very good, and we can customize the equipment to meet the needs, our distressed questions can be answered. When there is a problem with the equipment, you can give feedback to the manufacturer, and you can get a response and deal with it quickly, without worrying about the after-sales service being not good enough.

 

By slowly learning about related things, friends who didn't know enough about polystyrene machines before, and didn't know which manufacturers to work with more worry-free, will know what to do next. Only after carefully reading the detailed introduction shared above can friends who have more questions in their hearts make better decisions quickly.

 

How to screen the manufacturers of polystyrene machines?

 

In the processing and production of enterprises, many equipment can bring higher efficiency to its processing and production. Among them, polystyrene machine is one of the more commonly used equipment among many plastic foam manufacturers. Polystyrene machine has many Types, different types of equipment can be used in different production lines to play their functions and roles. Many people do not have a professional understanding of polystyrene machines, so that they don’t know where to start when screening equipment. Let's share with you how to screen the manufacturers of polystyrene machines.

 

Customized screening according to its products

 

Since different companies process different products, the functions that can be achieved by polystyrene machines are also different. Therefore, when selecting polystyrene machine manufacturers, people should clarify their own needs and provide them according to their customers’ needs. To check whether the equipment customized by the manufacturer meets the standard.

 

Filter according to its product quality

 

The quality of polystyrene machines produced by different manufacturers will have certain differences. Therefore, when selecting polystyrene machines, a comprehensive selection should be made according to the manufacturer’s qualifications, technology and equipment. These rigid conditions are It reflects the standard of whether a manufacturer has the corresponding strength, and it can also help people as a reference to select polystyrene machines with more quality assurance.

 

According to the above-mentioned related content introduction, the problem of how to screen polystyrene machine manufacturers is already clear. As a kind of granulation equipment, polystyrene machines are used by many manufacturers in the processing field. Therefore, understanding the working principle of its equipment can also help people to operate the equipment.
