Specification for construction acceptance of clean room

The so-called dust-free workshop refers to the removal of harmful substances, harmful air and other pollutants in the indoor space from a certain space, and the control of the temperature, cleanliness, pressure, air velocity and air distribution of the space, noise, vibration, lighting, and static electricity. . Today, the editor of Shenzhen China Clean Chemical Engineering Co., Ltd. will talk to you about the construction and acceptance specifications for dust-free workshops.

One of the construction projects: clean airtight doors

The clean airtight door is divided into two types: aluminum alloy door and color steel plate door. The door leaf is light, good rigidity, good airtight performance, good overall product performance, flat surface, smooth, corrosion-resistant, not easy to accumulate dust, beautiful and elegant appearance, flexible opening and closing, durable, with sound insulation, heat preservation, fire prevention and other advantages. Specific specifications can be designed and manufactured according to user requirements.

Construction project two: high-efficiency air supply outlet

This product is a 10,000-level, 100,000-level turbulent flow dust-free workshop newly built, and the terminal air supply device of the purification air-conditioning system of the renovation project. It can be widely used in purifying air-conditioning systems in the electronics industry, precision machinery, metallurgy, chemical industry, and medical, pharmaceutical, food and other sectors. This device is mainly composed of a static pressure box, a high-efficiency filter, an aluminum alloy diffuser, a standard flange interface, etc., with beautiful appearance, simple structure and reliable use. The air outlet is a bottom-mounted type, which has the advantages of convenient installation and replacement of the filter in the dust-free workshop. The high efficiency filter adopts mechanical compression or liquid tank sealing device to ensure that the air outlet is installed without leakage, reliable sealing, and good purification effect. General purification engineering can be applied.

Transfer window The transfer window is mainly suitable for the transfer of small goods between the clean area and the non-clean area, or between the dust-free workshop and the dust-free workshop. It can effectively reduce the opening times of the door of the dust-free workshop and reduce the pollution in the clean area. To a lesser degree. According to the requirements of use, the surface of the transfer window box can be sprayed with plastic, and the inner tank can be made of stainless steel, which has a beautiful appearance. The two doors of the transfer window adopt electronic control interlocking or mechanical interlocking devices, which can effectively prevent dust in the low-cleanliness area from being brought into the high-cleanliness area. It is a must-have product for purification workshops.

Construction project three: ventilation shaft

The ventilation shaft is a ventilation duct formed by the installation of color steel plates. It is generally installed in the clean area, and vents can be installed on it. The air flow in the clean area can be arranged reasonably through design, and the return air system and exhaust air system are often not used. There are two types of structure: triangular row columns and square columns.

Test and acceptance criteria for dust-free workshops

The purpose of controlling the air parameters of the clean room-to check whether the clean room meets the given cleanliness level. The control of air parameters must be completed either in the inspection phase of the clean room after the commissioning and commissioning work is completed, or in the use phase of the clean room. In various standards and recommendations (16), the test and control methods for air parameters of the clean room are formulated and proposed in detail. So far, these methods have become the common wealth of the vast scientific and technological circles. In a dust-free workshop, the following parameters should be controlled according to its use: 1. Determination of the test state; 2. The concentration of particles in the air; 3. The wind speed and unidirectionality of the airflow (for unidirectional airflow); 4 , Air volume and number of air changes; 5. Integrity of the final filter; 6. Air temperature and humidity; 7. Airtightness of the dust-free workshop; 8. Cleanliness of the surface of the dust-free workshop;

Determination of the test status: According to the design requirements, the air in the dust-free workshop is generally statically tested in the dust-free workshop, and dynamic testing is generally not done. If dynamic testing is required, other standards need to be formulated or referenced.

There are many construction projects in the dust-free workshop, so pay great attention to each project during acceptance. The country has also issued relevant acceptance specifications for this, and everyone can check and accept the dust-free workshop against the specifications. The above is the introduction about the construction of the clean room.
