Clean room engineering skills concept and clean room site construction content

Clean room is the air cleanliness to reach the specified level of space, its function is to control the pollution of particles and dust particles, to reach the satisfaction of precision product production and scientific activities, clean room is not limited to cleanliness, but different occupations and departments on temperature, humidity, lighting, noise, static electricity, micro-vibration have considerable requirements of the multi-function induction of the whole. Is a collection of building decoration and atmosphere relative partition closed decoration, purification air conditioning, pure water, pure gas, power electricity, lighting electricity, process pipeline and other professional skills in one of the products.

The so-called clean skills, is a new field of scientific skills, is a cross-professional, cross-department, cross-science inductive new branch of science. It is not only inextricably linked with many professions, many disciplines, but also has its own unique characteristics, clean skills are the means, pollution control is the purpose. The clean room is divided into industrial clean room and biological clean room according to its use. Biological clean room is divided into general biological clean room and biosafety clean room.

Clean room site construction

Construction content: dust-proof painting, water, heating, electricity professional in the skill sandwich pipe distribution, wiring, air conditioning unit device, maintenance, process interval, wall top frame, skeleton connection device.

To reach the clean level, it is necessary to have inductive methods, including process placement, building plane, building structure, building decoration, personnel and material purification, air cleaning methods, maintenance and management. Among them, the air cleaning method is the fundamental guarantee to achieve the cleanliness level. The construction of the clean room is based on the customer's needs to customize the cleanliness level, customize the process structure design, customize the equipment and other inductive optimization construction services.

A certain positive pressure value should be maintained between different grades of clean rooms, clean rooms and non-clean rooms, or clean rooms and outdoor. According to the grade of the clean room, the airflow distribution flow pattern of the clean room should be selected reasonably, and the vortex zone should be prevented in the operation area. Try to make the air that is sent into the room with a high degree of cleanliness reach the working area directly; The activity of air flow is conducive to the removal of particles from the return air outlet in the clean room.

It is necessary to have very clean air for the air supply of the clean room. Therefore, it is necessary to choose a high efficiency filter (when the cleanliness level is low) as a terminal filter to filter the air entering the clean room at the end. In order to maintain the terminal filter and extend its life, it is necessary to filter the air through the medium effect filter first.

The clean environment is for the production process service, clean room design is necessary to meet the environmental requirements of the production process, which is natural. Therefore, in the clean room design, the production process requirements for environmental parameters should be realistic, its area, height, temperature, humidity, cleanliness, etc., should be high, the low is low, not the higher the better.

In the production of the process plane division as far as possible to put the same level of clean rooms together, the cleanliness requirements of the process is set on the upwind side, the production of ash, toxic, harmful, flammable, explosive waste gas process equipment, containers as far as possible outside the clean area, if necessary in the clean area should be as far as possible to adopt closed methods to reduce dust and waste gas emissions.
