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 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...
