Through certain technical means, remove particles, bacteria, viruses, harmful gases and other pollutants in the air within a certain range, and at the same time, control the cleanliness, temperature, humidity, air pressure, wind speed, noise, and lighting parameters in the area Within a certain range of requirements. This project is called the purification project. This room is a clean room. The clean room originated in a hospital. In the 1880s, Lauder List realized that bacteria can cause infections in surgical wounds. Removing bacteria from the operating room can prevent infections, laying the scientific theoretical foundation for clean rooms. The clean room is developed in the precision instrument manufacturing industry. During World War II, people discovered that in order to improve the quality and reliability of guns, tanks, and aircraft equipment, the cleanliness of the production environment must be improved. Therefore, the first clean room for industrial production appeared in the United States. It can be said that the victory of World War II also contributed to the clean room. In the 1850s, the emergence of high-efficiency filters promoted the development of clean rooms. At this stage, clean rooms are widely used in industries such as microelectronics, optoelectronics, medicine, medical treatment, microorganisms, instruments, meters, aerospace, aviation, food, health products, and cosmetics. From our professional point of view, clean rooms are basically ubiquitous. There are many parameters that need to be controlled in the purification project, the most important thing is the number of particles, that is, the control of cleanliness. According to the maximum allowable concentration of particles of different particle sizes in the air, we mainly look at the particle concentration of 0.5 micron and 5 micron to divide the air cleanliness of the clean room into 100, 10,000, and 100,000 grades.

Between rooms with different levels of cleanliness, a room with a high level of cleanliness and an adjacent room with a low level of cleanliness must maintain a positive static pressure difference, and must withstand the short-term pressure difference when the equipment is started, so strict technical measures are required for careful operation : The floor of the clean room requires frequent flushing, and a double-layer stainless steel cover is used to drain the floor drain. In addition to the correct elevation and drainage slope to prevent pipeline blockage during construction, attention must also be paid to ensuring the surface accuracy of the floor drain itself, and the tightness and smoothness of the floor drain and the ground, so that it meets the requirements of cleanliness and sealing. The floor of the clean workshop should be flat, wear-resistant, easy to remove dust and clean, and not easy to accumulate static electricity, to ensure that the surface layer and the base layer are firmly bonded, not empty or cracked, and have a comfortable feeling. In order to withstand the undulating deformation and cracking of the ceiling panel under the static pressure difference and the pressure change when the equipment is started, attention should be paid to the integrity of the skeleton during construction, so that the deformation and sealing of the ceiling can be properly resolved, and the expected air-tight effect can be achieved; The surrounding areas of various holes such as lamps, vents, functional joints, observation windows, fire boxes, power distribution cabinets, etc., at the junction of different materials, are strictly in accordance with the requirements to complete the sealing and anti-crack measures to ensure the airtightness of the entire clean room ; Clean room Doors and windows should have good air tightness. Reliable sealing measures should be adopted for the structure and construction gaps of the walls, ceilings and floors of clean workshops. There is usually an expansion joint between the clean area and the non-clean area of the workshop. The joint is usually filled with polystyrene foam board, etc., the outdoor is equipped with a stainless steel cover, the indoor is pressed with a colored profiled steel plate, and the expansion screw is fixed. The edges of the outdoor cover are all embedded with sealant for sealing. Committed to demountable partition wall systems、clean room partition panels and clean room ceiling panel etc.
The ground is one of the most important parts of the clean maintenance structure of the pharmaceutical factory. In the selection of its ground materials, in addition to meeting the common requirements of the ground, the amount of dust on the ground, the difficulty of construction and the cost should also be considered. The general requirements are: 1. Good wear resistance; 2. It can resist the erosion of acid, alkali and chemical solution, and the material itself is pollution-free; 3. Anti-slip; 4. Antistatic; 5. The secondary construction is simple, and the ground can be processed without joints; 6 .Easy to clean and maintain. The abrasion resistance of the ground is the main requirement, which is also based on the need to reduce the amount of dust on the ground. At present, several types of floors commonly used in clean workshops of pharmaceutical factories are as follows: Ground Features Application Scope Double-layer ground can return air to the ground, good ventilation, high cost, poor flexibility, good comfort, vertical unidirectional flow clean room (large area) in pharmaceutical factories The terrazzo floor is smooth and wear-resistant, not easy to dust, good integrity, washable, anti-static, non-elastic control area, clean area of pharmaceutical factory The coating floor has the advantages of terrazzo, which is more wear-resistant but not drag-resistant, requires high substrate treatment, and is easy to curl and peel off the clean area of the pharmaceutical factory The floor of the coiled material sheet is smooth and wear-resistant, slightly elastic, not easy to dust, easy to clean, easy to construct; easy to generate static electricity, easy to be aging by ultraviolet light, and easy to build up a large area in the control area of the pharmaceutical factory The acid-resistant porcelain plate is corrosion-resistant on the floor; it is brittle and not impact-resistant, the construction is complicated, and the cost is high. There are corroded parts in the raw material workshop of the pharmaceutical factory The FRP floor is corrosion-resistant and has good integrity; it is easy to bulge, and it is appropriate to use a small area in the raw material workshop of the pharmaceutical factory. There are corroded parts Among the above-mentioned grounds, terrazzo ground is the most used before the implementation of GMP transformation in domestic pharmaceutical factories. In recent years, more and more pharmaceutical factories have used epoxy resin to self-level the ground. It is believed that terrazzo ground is prone to dust and construction is difficult. The quality is not easy to control and is not “modern” enough. Among them, easy to produce dust is the main reason why designers abandon the terrazzo floor.

Laboratory furniture is a special kind of furniture, because it is often in contact with water, electricity, gas, chemical substances and materials, and instruments and equipment during use. The characteristics of the times are more important to meet the requirements of laboratory scientific research on the functionality, robustness, corrosion resistance, and flexibility of installation and layout of the experimental environment. Therefore, laboratory furniture has higher requirements in terms of structure and materials. I. Material requirements (1) Countertop As the core component of laboratory furniture, the countertop is one of the most important parts of laboratory furniture. The countertop is particularly important for the laboratory bench of the chemical laboratory. Due to the different use environment, the countertop of the laboratory furniture should meet the special requirements of different laboratories. For example, the experimental benches of chemical laboratories need to be resistant to acid and alkali corrosion, the experimental benches of biological laboratories need to be antibacterial, and the experimental benches of physical laboratories need to be antistatic. Some experimental benches need to have these characteristics, so, Different experimental benchtops should be selected according to different needs. Nowadays, the commonly used test benches mainly include solid physical and chemical boards, epoxy resin boards, ceramic boards, and stainless steel boards. 1. Solid core physical and chemical board The high-quality multi-layer kraft paper is immersed in special phenolic resin and then thermoset at high temperature and high pressure. The surface paper is treated with special corrosion resistance, which has the characteristics of acid and alkali corrosion resistance, impact resistance, and heat resistance, which is economical and durable. The commonly used thickness of this kind of plate is 12.7mm, 14.6mm, 19mm. Commonly used specifications are 1.2m×2.4m, 1.5m×3m or 1.5m×3.6m. 2. Epoxy resin board It is mainly composed of reinforced epoxy resin, with smooth and safe arc-shaped edges, and is a chemical countertop that is integrally formed by a mold. The internal and external materials are the same, and it can be repaired and restored after damage. It has excellent acid and alkali corrosion resistance, impact resistance, and high temperature resistance (about 800°C). It can meet the requirements of laboratory corrosive chemical reagents, water tanks and other long-term water contact parts, so it is widely used. The thickness is generally 15mm or more. Commonly used are 1.5m×3m, 1.5m×3.6m and other specifications. 3. Ceramic plate It is made of clay and fired at high temperature, and the surface is glazed. It is basically impossible to perform secondary processing, and is generally used for ventilated countertops. The performance of the ceramic plate is very superior, the best acid and alkali corrosion resistance, high temperature r...
(1) The clean room is a place for human activities, and the cleanliness of the air reaches a certain level. The efficient and safe air purification system of the operating room in the clean laboratory ensures the sterile environment of the operating room, and can meet the highly sterile environment required for organ transplantation, heart, blood vessel, artificial joint replacement and other operations. The use of high-efficiency and low-toxic disinfectants and their rational use are powerful measures to ensure the aseptic environment in the general operating room. Laboratory purification ensures that the cleanliness of the operating table is up to standard. Generally, vertical laminar flow is generally used. The laminar flow operating room is a "positive pressure" environment. The air pressure depends on its different areas (such as operating room, sterile preparation room, brush The cleanliness of the hands, the anesthesia room and the surrounding clean area, etc.) varies with different requirements. Its function is to control particle pollution. A clean room is not generally clean, but has reached a certain level of air cleanliness. (2) The clean room is a multi-functional one. First of all, we need more professional cooperation with construction, air conditioning, purification, pure water, pure natural gas, etc. As far as pure gas is concerned, the process gas should also be purified. For example, in a disposable syringe factory, due to the designed process, the compressed air used in the injection molding workshop is not particularly purified. Each time the product is molded, a large amount of unpurified compressed air will be released, making the air cleanliness in the workshop unable to meet the requirements and causing pollution to the molded product. Therefore, dry air, compressed air, and inert gases that are in direct contact with drugs should be purified to meet production requirements. Secondly, several parameters need to be controlled, such as air cleanliness, bacterial concentration, air volume (air volume), pressure (pressure), sound (noise), light (illuminance), etc. (3) Regarding the quality of the clean room, in terms of importance, design, construction and operation management, that is to say, the clean room itself reflects its quality in the entire process from design to management. The difference between clean air conditioner and general air conditioner. Welcome to inquiry cleanroom glass partition wall、cleanroom ceiling grid system and clean room automatic doors etc.
The use of laboratory furniture is becoming wider and wider, covering schools, hospitals, pharmaceutical factories, research institutes, etc., but there are few well-known furniture brands around us. With the continuous increase in output, the quantity-based production and sales model no longer adapts to the development of the laboratory furniture industry. If manufacturers want to occupy a place in the industry, they must focus on product quality, improve brand awareness, change the traditional marketing model and maintain stability. Down-to-earth development. Nowadays, the concept of environmental protection has been deeply rooted in the hearts of the people, and people are paying more and more attention to the environmental protection of furniture. In order to further respond to the call for low carbon and environmental protection and meet the actual needs of consumers, manufacturers have begun to use environmentally friendly materials, and green laboratory furniture has emerged. If manufacturers want to establish independent marketing channels, they must pay attention to the quality and brand of their products. Only good quality and reasonable price can attract consumers to buy. Those salesmen who do not pay attention to product quality but blindly create a sensation through advertising cannot retain consumers. Such manufacturers are not destined to last long. Laboratory furniture, with the development of the industry and the needs of the market, decoration, ventilation, purification, gas and other related projects have also emerged, thus gradually forming an independent laboratory system engineering system, which is also its main feature. Enterprises are developing towards scale, specialization and branding. Under the impetus of well-known enterprises, small and medium-sized enterprises will develop with them. The clustering of the industrial structure has formed a regional economy with local characteristics, using the original local resource advantages, and at the same time driving the development of the local economy. The shift towards functionalization and diversification, product types and markets continue to be subdivided, laboratory furniture, bathroom furniture, children's furniture and elderly furniture have emerged, and new and natural materials have been continuously applied to the production of furniture. The industrial structure is more specialized and gradual. Enterprises have changed the previous development model of unlimited expansion of production scale, and then developed more subdivided and specialized products. Each link of the industrial chain has become more subdivided, showing a gradual trend. Specializing in the laboratory table、Fume hood、 Laboratory sink and Laboratory cabinets .
