Necessary measures to ensure the cleanliness of clean rooms

1. Cleanliness of people

Cleanliness measures mainly include washing with water, changing shoes and clothes, and air blowing.

The pollutants emitted by human body are mainly self-generated pollutants and carried pollutants.

There are three kinds of dust particles carried by human body; One is the external environmental pollutants randomly attached to hair, clothes and shoes; And the residual pollutants on clothes and shoes. The other is personal smears, such as hair oil, perfume, eye cream, powder and so on. The third is the wear and tear of clothing.

Human body is one of the main bacteria sources in clean rooms.

in view of the above situation, the personnel entering the clean room should take some necessary cleaning measures. Measures for personal cleansing include:

1) washing with water

washing with water to remove temporary attachments and accumulated body surface discharge on hands, face and even whole body epidermis.

2) changing clothes and shoes

In order to reduce the pollutants brought into the clean room from the outside, people who enter the clean room generally change their shoes and clothes. Generally speaking, the requirements for work clothes are not only high surface cleanliness, but also easy to remove pollutants, which can cover most of the human body like a filter and make the dust bacteria scattered by the human body be filtered on one side of the human body, and at the same time, it is not easy to generate static electricity. Outgoing shoes carry the most dirt, so they must be pretreated by washing, vacuuming and sticking at the entrance to avoid excessive contamination of the entrance hall.

3) air shower

air shower is to use high-speed clean air to sweep the temporary attachments of the whole body clothes and nude surfaces. The measures of washing, changing clothes and air blowing can reduce the external pollutants carried by human body and clothes, reduce the pollution caused by direct contact, and isolate most of the body and underwear from indoor air to a certain extent.

The blowing time of human body in the air blowing room is related to the blowing speed, and the shorter the blowing time, the higher the blowing speed is. On the contrary, it can be smaller. Generally, the blowing time is between 2~6s.

The air shower room generally consists of a shower fan, primary and secondary air filters, high-efficiency filters, static pressure boxes, nozzles, etc.

4) Air curtain and air lock

Because the shower chamber is often located at the entrance of the clean area, it is directly adjacent to the clean area, and the doors at both ends are often interlocked to open and close, so it is not only used for personnel purification, but also serves as an air lock to prevent outdoor pollution. At the entrance of a clean room with low requirements for personnel purification, an air lock is sometimes used with an air curtain, and a unit with a medium and high efficiency filter is arranged on the top plate at the entrance of the clean room, and air flow is sprayed downwards through slits to form an air curtain for shielding pollution.

2. Purification of materials entering the clean room

Generally speaking, materials entering the clean room should be cleaned and cleaned before being transported into the clean room, so as to reduce the amount of dust generated by materials in the clean room.

small items entering the clean room generally enter through the transfer window from the clean room and the outer corridor or between the clean room and the clean room (adjacent rooms with different cleanliness levels).

generally, transfer windows are box type and rotary type.

3. The air entering the clean room is clean

During the operation of the clean air conditioning system, the air filters used at all levels must be intact without damage and leakage. During the operation of the clean air conditioning system, in order to prevent the air supply system from bringing dust particles that should not enter the room into the room, it is necessary to check the leakage of the primary, secondary and terminal air filters used in the system regularly.
