Cleanroom > BOCLEAN

Recently due to the development of high-tech industries such as electronic industry, precision machinery industry and its products are precision, miniaturization, high quality and high reliability is required. Electronic Factory, FILM precision machinery factory or factories, etc. resulted in the production of products suitable for the intended use, and the defect of the product is attached to the product being manufactured Indoor rich particulate hinder the reliability and yield of the product (cost of production) because they have a huge impact on a part of the action takes place the entire plant or important to maintain a clean environment for the need to respond to be.
Industrial Clean Room clean space for this purpose is called, often state that requires very high purity.

Closest to prevent product contamination, spoilage protection and to prevent infection of patients with aseptic pharmaceutical factory, food factory, hospital operating rooms, etc. of the status is required.
General caught up in a high-performance Filter removes bacteria, but viruses compared to bacteria very much because it is difficult to remove by itself. However, most of the bacteria or virus, so the presence of suspended particulate matter in the air attached to the particulate matter in the air by removing the fungi also can be removed. Sterilized by use of drugs, such as ultraviolet radiation or lithium chloride to remove the bacteria in the air that usually, but in recent years through the high-performance Filter sterile closer to purify the air by the state can be obtained.

We call it as Biological Clean Room which is the clean space for this purpose.

Clean Room airflow rate indicates that the general rules on the selection. Airflow rate (1) Average speed (m / sec or ft / min), or (2) number of hourly ventilation (number / hour) regulations.

(U=Single direction of flow , N = Non Single direction of flow M = interflow)
1 Typically used in a single direction of flow (laminar flow) if the average airflow rate.
2 Number of hourly ventilation is calculated by the following equation.

Hourly number of ventilation [count / hr] = average airflow velocity (m / sec) x discharge area (㎡) x3, 600sec interior volume (㎥)

Patterns of Air Flow
Laminar expression (vertical, horizontal) turbulence equation, and soul - flow, tunneled, and the characteristics of each, determined by considering the intended use.

The cleanliness of clean room is to be decided by the extension of each products requirements.. Cleanliness level is achieved by examining the number of the airflow method, ventilation, indoor pressure enough

Considering workability, determines the lay - out to meet the cleanliness.
Isolate dust required job from other work.
Also recommends to consider people , stuff of entrances, driveways, utility, maintenance, comprehensive and regurgitating.

A smooth interior surface, the airflow is disturbed or do not allow dust to accumulate in the structure.
As well as the small dust particles are not attached, the material is easy to clean.
Work with the materials with moisture resistance, chemical resistance, chemical resistance could be used depending on the working contents.

Cleanroom ambient pressure maintained for dust control, air shower (for man entry and exit), pass box (stuff allowed for), safety damper (indoor pressure adjustment) for the storage and packing of the device screen Stow car. Clean lacquer.
Thus, each feature must be fully understood.

Goods imported from outside and the worker, these are the major cause of a rash.
Wujin clothing and makeup of problems, including the basic knowledge are required for the cleanroom worker.

Water Supply District, a way for devices such as gas, electricity, energy supply, airflow, taking into account the lay out of fiexibility and need to be determined.
Maintain cleanliness, we need to be careful , not to be decreased.
