Description

Partition panel with foamed aluminum core material, manufacturing method thereof, and partition wall

The invention relates to a partition board, and in particular to a partition board and a partition wall with foamed aluminum core material.

A clean room refers to an environment with a low pollution level. By removing pollutants such as fine dust particles in the air in a closed space, a fairly clean environment is obtained. Pollutants in the air include dust, microorganisms, suspended particles, and chemical volatile gases. Clean rooms are widely used in industries that are particularly sensitive to environmental pollution, such as semiconductor production, biochemical technology, precision machinery, pharmaceuticals, hospitals, aseptic food processing and manufacturing industries, etc. Among them, the semiconductor industry has requirements for indoor temperature, humidity, and cleanliness. Especially strict, it must be controlled within a certain range of requirements so as not to affect the process.

Common types of partition boards (also known as warehouse boards) used in clean rooms, such as paper honeycomb, rock wool, PU foam and other types of partition boards.
