A clean room is a specially designed room that removes particles, harmful air, bacteria and other pollutants from the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air flow velocity and distribution, noise, vibration, lighting, and static electricity within a certain demand range.That is, no matter how the external air conditions change, the interior can maintain the cleanliness, temperature, humidity, pressure and other performance characteristics of the original set requirements.
Clean RoomThe main function is to control the cleanliness, temperature and humidity of the atmosphere that products (such as silicon chips) contact, so that products can be produced and manufactured in a good environmental space, which we call the clean room.According to international practice, the dust free purification level is mainly determined by the number of particles with a diameter greater than the classification standard per cubic meter of air.That is to say, the so-called dust-free is not without a little dust, but controlled in a very small unit.Of course, the particles that meet the dust standard in this standard are very small compared with our common dust, but for the optical structure, even a little dust will have a very large negative impact, so in the production of optical structure products, dust-free is an inevitable requirement. Introduction to design requirements of clean room With the increasing demand for clean rooms in production, the requirements for the cleanliness of the clean room decoration project are becoming higher and higher. How to grasp each construction process is an important factor for achieving the cleanliness required by the design.How high the cleanliness level of the clean room can be achieved is also a factor to measure how high the construction quality can be achieved by a construction enterprise. 1、 Definition of clean room A clean room is a specially designed room that discharges particles, harmful air, bacteria and other pollutants from the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air flow velocity and distribution, noise, vibration, lighting and static electricity within a certain range of requirements.That is, no matter how the external air conditions change, the interior can maintain the cleanliness, temperature, humidity, pressure and other performance characteristics set by the original requirements. IIClean RoomThe composition of the clean room is composed of the following systems, and any of the system elements is indispensable, otherwise it will not form a complete and high-quality clean room: a. Ceiling system: including suspender, main keel, secondary keel and ceiling. b. Air conditioning system: including air handling equipment, air conveying equipment, air distribution equipment, cold and hot control sources, automatic regulation control devices, etc. c. Partitions: including windows and doors. d. Floor or ground: including epoxy floor, raised floor, etc. e. Lighting fixtures.
3、 Clean room construction Clean room construction is mainly to keep tight and clean.
1、Clean RoomThe main structure of the clean room is generally reinforced concrete structure with brick wall enclosure. This process is the outermost clean barrier of the clean room. Attention should be paid during construction: a. The holes on concrete and brick walls should be repaired to reduce wall cracks; b. Measures to prevent cracks shall be taken at the joint of concrete and brick wall; c. The plastering of the interior and exterior walls should be carried out in layers to prevent cracks and hollowing on the walls, especially the interior walls. It is a wrong idea to think that there are clean wallboards inside, so plastering is not necessary. This layer of plastering is very important. The decoration of the clean room will greatly help the later cleaning, reducing dust and noise by 10%
