Code for Construction and Acceptance of Clean Room A clean room is a room with a high degree of environmental pollution control. It is mainly used for production, experiment and scientific research in biological, pharmaceutical, electronic and other industries. In order to ensure the use effect of the clean room, the construction and acceptance must be carried out in strict accordance with the specifications. This article will introduce the relevant contents of the clean room construction and acceptance specifications. 1、 The design of clean room construction specification requires that the design of clean room should comply with relevant standards and specifications, and the parameters such as cleanliness level, area, height, etc. should be determined according to the actual needs. At the same time, the design of the clean room should take into account such factors as use function, safety, energy conservation, environmental protection and aesthetics. The materials in the clean room shall have the characteristics of non adsorption, non particle release, easy cleaning, abrasion resistance, fire prevention, anti-static, etc. Common materials include stainless steel, aluminum alloy

The setting of high-efficiency air supply outlets in dust-free workshops requires that dust-free workshops have very high requirements for air quality in the production process. As an important part of the air purification system of the dust-free workshop, the setting requirements of the high-efficiency air supply outlet directly affect the air quality of the workshop. The following are some requirements for the setting of efficient air supply outlets in the dust-free workshop: number and location of air outlets: the number and location of efficient air supply outlets shall be reasonably calculated according to the area, floor height and production process requirements of the dust-free workshop. In general, high-efficiency air supply outlets should be evenly distributed throughout the workshop to ensure uniform air flow in the workshop and achieve good purification effect. Air velocity at the air outlet: the air velocity at the high-efficiency air supply outlet shall be determined according to the production process requirements and the air cleanliness level. Generally speaking, the wind speed of the high-efficiency air supply outlet in the dust-free workshop should be controlled at 0

Requirements for laminar flow sampling vehicles in the clean workshop of the pharmaceutical factory Laminar flow sampling vehicles require 100000, 10000, 1000, 100, etc. The laminar flow sampling vehicle of pharmaceutical factory is generally 100000 grade, and the box is made of 304 stainless steel. In the clean workshop of the pharmaceutical factory, the laminar flow sampling vehicle is an important equipment for sample collection and analysis. The requirements of the laminar flow sampling vehicle are as follows: cleanliness requirements: as the laminar flow sampling vehicle is mainly used for collecting and analyzing samples, its internal cleanliness requirements are very high. The interior of the laminar flow sampling vehicle shall be thoroughly cleaned to avoid sample contamination. Laminar flow requirements: the laminar flow sampling vehicle shall adopt the laminar flow design to ensure that the sample will not be polluted by the external air during the collection and analysis process. Laminar flow design can effectively reduce the amount of particles and microorganisms in the air
