What Is a Modular Cleanroom?

Clean work shed is an air purification equipment that can provide a local high clean environment. It is mainly composed of box, fan, primary air filter, damping layer, lamps, etc., and the case is sprayed with plastic. The product can be hung and supported on the ground. It has a compact structure and is easy to use. It can be used singly or in multiples to form a strip-shaped clean area.

Clean work shed

Right!

Clean work shed is a kind of

Clean work shed (referred to as:

1.Frame: industrial aluminum (or stainless steel square pass, iron square pass spray plastic) as the frame is stable, beautiful, no rust, no dust;

2. Anti-static curtains: Use anti-static curtains (or tempered glass) around, good anti-static effect, high transparency, clear grid, good flexibility, non-deformation, and not easy to age;

3.Fan filter unit

Fan from

1. Can be used alone or in combination.

2. Compared with civil or assembly type 100 clean room, it has less investment, quick effect, easy installation and low operating cost.

3. Modular structure, easy to improve cleanliness level, strong expandability, and high reuse value

4. Easy to move (can be installed

1. Dust volume: Dust volume in clean shed

From the equipment, it can be considered to be exhausted through local exhaust, and does not flow into the room. The dust emitted by products and materials during transportation is generally very small compared to the amount of dust emitted by the human body, and can be ignored; The application of dust from building surfaces is also very small, generally accounting for less than 10%, and the dust is mainly from people, accounting for about 90%. In terms of the amount of dust emitted by people, due to the improvement of clothing materials and styles, the absolute amount of dust emitted has also continued to decrease.

A. Material: Cotton has the largest amount of dust. The following are cotton, Queliang, antistatic pure polyester, and nylon.

B. Style: Large hanging type has the largest amount of dust, followed by the top and bottom split type, and the full cover type is the least;

C. Activity: The amount of dust generated during the action generally reaches 3-7 times of the rest time; D. Cleaning: The amount of dust generated when washed with a solvent is reduced to one-fifth of that washed with ordinary water. The amount of dust on the surface of the indoor maintenance structure is based on the ground. The amount of dust on the surface corresponding to about 8 square meters of ground is equivalent to that of a stationary person.

2. Bacterial volume: pollution from staff

1) Skin: Humans usually complete the complete skin replacement every four days, and humans lose about 1,000 pieces of skin per minute (average size is 30 * 60 * 3 microns);

2) Hair: Human hair (about 50-100 microns in diameter) has been falling off;

3) Drooling: including sodium, enzyme, salt, potassium, chloride and food particles;

4) Daily clothing: particles, fiber, silica, cellulose, various chemicals and bacteria;

5) Human being still and sitting will produce 10,000 particles larger than 0.3 micron per minute;

6) Humans will produce 1,000,000 particles larger than 0.3 micrometers per minute when they perform actions on the head and torso;

7) Human beings walking at a speed of 0.9m / s will produce 5000000 particles larger than 0.3 micrometers per minute.

Analysis of foreign test data can be considered:

(1) When the staff wears sterile clothing in a clean room: the amount of germs during stationary is generally 10-300 / min. The amount of germs during general human activity is 150-1000 / min. People walk quickly When the germ volume is 900-2500 / min. Person;

(2) A cough is usually 70 ~ 700 persons / min. A person sneezes generally from 4000 ~ 62000 persons / min. Person;

(3) The amount of bacteria in normal clothes is 3300 ~ 62000 / min. Person;

(4) Bacterial amount without mask: with mask: 1: 7 ~ 1: 14;

(5) Bacteria volume: Dust volume 1: 500 ~ 1: 1000;

(6) 878 bacteria / min. Persons during the operation

Therefore, it can be known that the static germicidal amount of aseptic workers in clean rooms generally does not exceed 300 per minute, and the dynamic germicidal amount does not exceed 1,000 per minute / person. It is feasible to use this as a calculation basis.
