Dust-free workshop Dust-free workshop is also called clean workshop, clean room and clean room. First, the definition of clean room Clean room is also called clean room or clean room. It is the basis of pollution control. Without a clean room, it is impossible to mass-produce pollution-sensitive parts. In FED-STD-2, a clean room is defined as a room with materials and equipment for air filtration, distribution, optimization and construction, in which specific and routine operating procedures are used to control the concentration of airborne particles to achieve an appropriate level of particle cleanliness. Clean room refers to a specially designed room that removes particulate matter, harmful air, bacteria and other pollutants in the air within a certain space range, and controls indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise and vibration, lighting and static electricity within a certain demand range. In other words, no matter how the outside air conditions change, the room can maintain the original requirements of cleanliness, temperature, humidity and pressure. Two. The construction methods of clean workshop can be divided into two types: civil construction and assembly, of which assembly is widely used. The assembled clean workshop system is mainly composed of air conditioning air supply, return air and exhaust system, with primary, middle and high air filtration; Power and lighting system; Monitoring, alarm, fire control and communication system of working environment parameters; People flow and logistics system; Process piping system; The implementation contents required for maintaining the structure and electrostatic ground treatment have formed the whole equipment and equipment supporting and building installation contents included in the air conditioning purification system project. Its installation and use have the following characteristics:1> All the maintenance parts of the assembled clean workshop are processed in the factory according to the unified module and series, which is suitable for mass production, stable quality and rapid supply. 2> Flexible, suitable for supporting installation of new plants and purification technical transformation of old plants. The maintenance structure can also be arbitrarily combined according to the process requirements, which is convenient to disassemble. 3> The auxiliary building has a small area and low requirements for the decoration of earth buildings. 4> air distribution is flexible and reasonable, which can meet the needs of various working environments and different cleanliness levels. Heat-insulating sandwich panel Heat-insulating sandwich panel is a new type of building panel, which is formed by pressing and heating the inner and outer layers of steel plate (aluminum plate, stainless steel or decorative plate) and self-extinguishing polystyrene foam plate (other fire-extinguishing materials) with high-strength adhesive. The thermal insulation sandwich panel is beautiful in appearance, colorful and diverse, light in weight, high in strength and quick and convenient in construction. It is assembled from plates and does not need large lifting equipment or wet operation. It integrates load-bearing, heat preservation, arson and decoration, and does not need secondary decoration. It can be widely used in long-span structural roofs, walls, insulation and fire-proof workshops, purification workshop, cold storage, refrigerated trucks, container houses, existing building mezzanines, etc. Clean sealed doors Clean sealed doors are divided into aluminum alloy doors and color steel doors. The door leaf has the advantages of light weight, good rigidity, good sealing performance, good overall product performance, smooth surface, corrosion resistance, difficult dust accumulation, beautiful and elegant appearance, flexible opening and closing, durability, sound insulation, heat preservation and fire prevention. Specific specifications can be designed and manufactured according to user requirements. Efficient air supply outlet This product is the terminal air supply device of air conditioning system in the new construction and reconstruction project of 10,000-class and 100,000-class turbulent clean rooms. It can be widely used in cleaning air conditioning systems in electronic industry, precision machinery, metallurgy, chemical industry, medical treatment, pharmacy and food departments. This device is mainly composed of static pressure box, high efficiency filter, aluminum alloy diffuser and standard flange interface. Beautiful appearance, simple structure and reliable use. The air supply outlet is installed at the bottom, which has the advantage of convenient installation and replacement of clean room filters. The high-efficiency filter adopts mechanical compaction or liquid tank sealing device to ensure that the air outlet is installed without leakage, with reliable sealing and good purification effect, which can be applied to general purification projects. Conveying Window The conveying window is mainly suitable for conveying small goods between clean areas and non-clean areas, or between clean rooms, which can effectively reduce the opening times of clean room doors and minimize the pollution of clean areas. According to the use requirements, the surface of the transmission window box can be sprayed with plastic, and the inner container can be made of stainless steel, which is beautiful in appearance. The two doors of the transmission window adopt electric control interlocking or mechanical interlocking devices, which can effectively prevent dust from being brought into the high clean area from the low clean area. It is a must-have product in purification workshop. Clean sealing window The clean sealing window can be made into a circular or triangular frame by using R60 or R44 series profiles according to the design requirements of users. Clean sealed lamps Clean sealed lamps are divided into ordinary and emergency types. Usually in the form of a double tube. Among them, the emergency type can also be used as the ordinary type under normal circumstances. In the case of sudden power failure in the factory building, lighting can be maintained without a separate power supply system. In terms of materials, there are two kinds of clean and airtight, stainless steel and paint, and masks are transparent and opaque. Ventilation shaft Ventilation shaft is a ventilation pipe formed by installing colored steel plates. Generally installed in a clean room, which can be equipped with vents. Through the design, the air distribution in the clean area is reasonable, and the return air system and exhaust air system are often used separately. There are two structural forms: triangular column and square column. The ground treatment adopts high-quality ground materials, forming a smooth, dense, chemical-resistant, colorful, non-toxic and easy-to-clean surface layer on the original ground, which has excellent physical properties, including high adhesion, compressive strength, bending strength and good impact resistance and wear resistance. Mainly suitable for clean floors. Structural column wrapping structure The structural column wrapping structure is suitable for the situation that there are cement structural columns or steel structure columns in the clean area. After installing the color steel plate, the workshop is beautiful and meets GMP requirements. Distribution box (cabinet) The distribution box (cabinet) in the clean area can be installed openly or concealed according to different requirements. Its concealed structure is similar to ventilation column well or structural column. Glass curtain wall Glass curtain wall is mainly used to separate clean area from non-clean area or production area from non-production area, providing convenience for managers or visitors. Laminar hood Laminar hood is an air purification device which can provide local high cleanliness environment. It mainly includes box, fan, primary air filter and high efficiency air filter. Damping layer, lamp, etc. The box is made of plastic spraying or stainless steel. The product can be hung and supported on the ground, with compact structure and convenient use. Can be used alone, but also can be connected to form a strip-shaped clean area. Widely used in precision machinery, electronics, pharmaceuticals, food, fine chemicals and other departments. Process Pipelines With the development of pharmaceutical industry, the material requirements for liquid medicine pipes are very strict at present. At present, 3 16L (American brand) pipes and fittings are mostly used, and quick connection installation is adopted. In this respect, our company has rich installation experience, and the method of single-sided welding and double-sided molding not only makes the pipeline beautiful, but also meets the use requirements.
