Carbon dioxide, as a component of air, can be produced from liquid air or as a byproduct of building materials and food industries. It is inexpensive and harmless to the atmospheric ozone layer, with a high mass molar ratio and high foaming ratio. Used to replace auxiliary foaming agents such as chlorofluorocarbons, it not only has good environmental benefits, but also considerable economic benefits. Introduce the important role of carbon dioxide booster pump in foaming process.

1. The carbon dioxide booster pump can increase the pressure required by the low-temperature liquid carbon dioxide booster extruder. Different pneumatic CO2 booster pumps can be used to match different models.

2. The unique design process ensures that the pump will not become unusable due to low medium temperature during operation. The high-voltage end can be equipped with a high-voltage buffer tank for stable output, which has a significant effect.

3. The pump body is designed and used with 304 stainless steel and aluminum alloy, and the non-standard design of the one-way valve diameter ensures that it will not be blocked due to icing. Partial material oxidation treatment ensures the durability of the pump body

There are numerous applications in processes such as XPS extruded board and insulation board.

The application of Fuente brand carbon dioxide injection system is developed and designed based on the internal core component of liquid carbon dioxide dedicated pump.

The technology of carbon dioxide pressurization system in the production process is currently in the stage of improvement, but of course, there are still some shortcomings in some aspects of carbon dioxide foaming technology. However, the development and innovation of technology will easily solve this problem.

The general liquid carbon dioxide foaming process uses ZTD15-2 for filling and injection, with a flow rate of about 2-5kg/min. Multiple pumps can be used for matching according to different filling methods.
