Small and medium-sized clean room expansion or renovation considerations

The height of the old factory buildings is about 3m. The area and shape are different from the actual needs. Generally, the air ducts cannot be installed as usual, and the technical interlayer and special air conditioning system are installed. According to the basic principles of air purification, in practice, we have explored a very practical dust-free workshop technical transformation method, especially suitable for the technical transformation of small and medium-sized clean room. The following is introduced as follows: 1. Structure mode The principle of using the ordinary air conditioner to directly send the cold air to the air mainstream area to transform the clean room. The dust-free workshop is built in the old factory, the room height is 3m, and the clean room wall is made of sandwich color steel plate. Constructed, about 2.4m high, the top of the clean room is a fan...

Why should the relative humidity of Shenzhen clean room be strictly controlled?

The poor control of the relative humidity of the clean room in Shenzhen may result in a decline in the overall performance of the clean room and a series of effects. 1. Bacterial growth. Bacteria and other biological contaminants (mold, viruses, fungi, mites) can actively multiply in environments with relative humidity above 60%. Some flora can grow when the relative humidity exceeds 30%. When the relative humidity is between 40% and 60%, the effects of bacteria and respiratory infections can be minimized. Therefore, the relative humidity of the clean room should be controlled within a certain range. 2, clean room staff feel the comfort of the room temperature range. The same range of humidity in the range of 40% to 60% is also...

What is the safety of the clean room ventilation system?

At present, the development of clean laboratories in China has entered a new stage of development. In the construction of laboratories, there are strict requirements for ventilation control. Cleanliness, pressure, and self-control are all carried out around HVAC. This is laboratory construction. An important part of the project is also an important aspect of the construction of laboratory safety. The primary problem solved by the ventilation design of the laboratory is the safety problem. The ability of the fume hood to capture the dust collection should meet certain standards and regulations. The direction of the airflow is to the laboratory, and the laboratory should maintain negative pressure at any time. The traditional laboratory control method uses a constant air volume control method. In the 1970s, bistable control appeared again...

What are the treatment methods when the stainless steel air shower is faulty?

First, the power switch usually has three places to cut off the power supply: 1. The power switch of the outer box; 2. The control panel of the inner box; 3. The outer box on both sides (the power switch can be prevented here) Cut off the power supply in an emergency, effectively improving the personal safety of the staff). When the power indicator does not work, do not check the above three stainless steel air shower power supply. 2. When the stainless steel air shower chamber fan is not working at the emergency switch. When the air shower is not working, check the emergency switch of the outdoor shower box for the first time. If it is determined to be cut off, press one hand and turn it to the right to release the hand...

What are the important precautions when installing a clean room pure water system?

The installation confirmation of the clean room purified water system is mainly based on the production requirements, checking whether the installation of the water treatment equipment and the piping system is qualified, checking the calibration of the instrument and the preparation of the operation and maintenance procedures. The installation confirmation of the purified water preparation is to check whether the installation conforms to the design and specifications after the mechanical equipment is installed. The purified water treatment equipment mainly includes mechanical filter, activated carbon filter, electrodialysis, water pump and distilled water machine. , mixed bed ion exchangers, etc.; inspection items include electrical, connecting pipes, compressed air, instruments, water supply, filters, etc. installation and connection. Installation confirmation of pipeline assignment...
