Purification engineering principles: the need to ensure a clean process to implement the local operating area clean (pipeline), a separate area of ​​the equipment clean and staff through a dedicated clean clothes isolated, controlled ventilation frequency to control the level of cleanliness.

Purification engineering design and construction: In a pharmaceutical packaging plant engineering, the application of improved early color steel polystyrene sandwich panels, plates connected by the word of aluminum and aluminum and other interior arc. To ensure air tightness (interior and exterior clean at a different level, through pneumatic height adjustment is not reduced level) with transparent sealant.

Mounting plate connection structure restrictions, using the word aluminum connection purification houses some deficiencies, each mounted with two apparent sewn seam, increasing the number of wall joints, the apparent poor material is not uniform, the color is inconsistent , fire level is insufficient.

Inner socket, high fire resistance Caigangyanmian board after the advent of the Interior for the purification plant increased. Caigangyanmian board through the inner socket plate fastening male and female plugs natural, uniform and fine cracks, the word used in the past to make up for the lack of connection of aluminum is widely used in the electronics industry, the pharmaceutical industry, aerospace industry.

Decontamination common quality defects installation process:

1, plate assembly process is not correct, affect the installation schedule and product protection should be used in order: primary and secondary keel ceiling installation - wall - ceiling roof - windows and doors - the income side - self-leveling epoxy mortar floor.

2, strict control of vertical mounting plate and board formation, strict product protection, protective film is removed after the installation is complete, clean the board at the seams after sealant.

Air conditioning ducts and other equipment installation must tie in with the progress of the project can also be installed first inspection, air outlet and the HEPA filter must be independent fixed in the ceiling board is strictly prohibited and not allowed after special-shaped walkway back to the wind pipe. Air conditioning ducts installed to maintain tightness, anti-clean air loss and increased energy consumption standards of purity.
