The clean room roof and siding materials of the purification project are mostly made of color steel sandwich panels (short for color steel sandwich composite panels). Color steel sandwich panel is divided into two kinds of mechanism board and manual board. When the sandwich material is polystyrene board, paper honeycomb board, aluminum honeycomb board and polyurethane board, the color steel sandwich board is machine-composited, called mechanism board. The use of organic materials such as polystyrene board as the core, although the price is low, the construction is convenient, but can not meet the clean room ceiling and wall (including the sandwich material) should be non-combustible, and the purification project should not use organic compound According to the provisions of the materials, the sandwich material of the color steel sandwich panel used for the clean room should be a non-combustible body, such as rock wool, aluminum honeycomb, glass magnesium plate and the like. The color steel Cleanroom sandwich panels made of rock wool and glass magnesium plates are mostly made by hand, so it is called hand-made color steel sandwich panels. The construction technology of color steel sandwich panel is introduced in "Cleanroom Construction, Inspection and Operation Management". This chapter mainly introduces the construction technology of the color steel sandwich panel.

Purification engineering

The decoration project of the color steel sandwich panel of the purification project is completed in the outer structure of the civil construction, the outer door and window are installed, the air-conditioning air supply and return air pipes above the indoor ceiling, various water pipes, cable trays and their wiring pipes, Special renovation works carried out after the completion of various projects such as pipeline insulation. The reason why it is special is because this decoration is different from the interior decoration of civil buildings. Civil decoration mainly reflects the styles required by designers and users, and different styles have different shapes. Such as: European decoration as much as possible with a variety of lines, reliefs and decorative columns and other decorative objects to decorate, increase the level of space, coupled with gorgeous lighting to produce a magnificent effect.

The decoration requirements of the purification project are very special. It is not allowed to use protrusions such as decorative lines. The yin and yang angles should be made into a circular arc shape, that is, the "face" is replaced by the "face". The wall and ceiling should be flat, smooth and seamless or the joints should be flat and tight. The general principle is that the ceiling and the wall do not produce dust, no dust, bacteria, easy to clean, and corrosion resistant. Lighting fixtures should use clean, non-dusting, easy-to-clean lamps, and the colors are light and fresh. It can be seen that the untrained civil decoration company is totally incompetent. To meet the decorative requirements of the clean room, the construction process of the purification project is critical.
