First, the application of nitrogen in polyethylene processing

Nitrogen, as one of the gases in air separation process, plays an important role in polyethylene processing. On the one hand, nitrogen can be used as an inert gas to avoid the reaction of impurity oxygen in the air with polyethylene, which affects the quality and performance of processed products; On the other hand, nitrogen can also help stabilize temperature and pressure in the process of extrusion, injection molding, calendering and other polyethylene processing to ensure the smooth progress of processing.



Second, the impact of nitrogen on polyethylene processing

1, the impact on the atmosphere: nitrogen at room temperature is colorless, odorless, non-toxic gas, in the polyethylene processing as an inert gas role, reducing the oxygen content of the air, to avoid the oxidation of oxygen to polyethylene, improve the quality and performance of the product.

2, the impact on temperature: in the polyethylene extrusion, injection molding, calendering and other processing processes, nitrogen fluidity, thermal conductivity, cooling and other physical properties, can effectively control the temperature, maintain the required temperature range in the processing process, to ensure the quality of the product.

3, the impact on pressure: nitrogen increases the pressure during the processing, improves the flow of the melt, speeds up the discharge rate of the melt, and increases the production efficiency. jpg" style="width: 800px; height: 600px;"  />

Why use a nitrogen machine instead of bottled nitrogen and liquid nitrogen

1. The danger and inconvenience of bottled nitrogen and liquid nitrogen: the pressure of bottled nitrogen is high, there are many safety hazards in the use process, frequent bottle changing and no timely supplement affect production; Due to its low temperature and high pressure, the use of liquid nitrogen needs special care, and the loss in the process of liquid nitrogen gasification causes waste.

2, the nitrogen machine is easy to use, a key boot output nitrogen, no special care, the use of less than half of bottled nitrogen and liquid nitrogen, can effectively save enterprise costs, nitrogen machine safety can also reduce the occurrence of accidents in the production process.

Fourth, the correct selection of nitrogen machine

1, the use of high purity nitrogen machine, can improve the processing quality;

2, adjust the flow of the nitrogen machine, control the processing temperature and pressure;

3, under the protection of nitrogen processing technology, open the ventilation equipment after the end of the processing to avoid nitrogen accumulation, resulting in safety risks;

4, in the process of using the nitrogen machine, strengthen the publicity and training of the operating procedures and precautions.

Through the application and influence of nitrogen in polyethylene processing, it is not difficult to see the importance of nitrogen in polyethylene processing. Under the premise of correct use of nitrogen, processing parameters such as temperature and pressure can be effectively controlled to improve the quality of polyethylene products. At the same time, Troy also reminds engineers to strengthen safety awareness and management when using nitrogen to prevent safety accidents.
