PUR and PIR refer to the chemical composition and structure of rigid polyurethane foam. Either PUR or PIR can be used as a core material and a variety of rigid or flexible materials as the surface material to be composited by various processing methods. PUR composite panel refers to the polyurethane rigid foam as the core material, which generally adopts a formula system of polyether polyol, lower isocyanate index and flame retardant. The skeleton structure of the foam is composed of urethane segments. It can only be used below 100 degrees Celsius. PIR composite panel refers to the polyurethane rigid foam as the core material, which generally uses polyester polyol, high isocyanate index (above 250), and uses no or less flame retardant formula system. The skeleton structure of the foam is made of urethane The product is composed of the chain segment and the urethane modified isocyanurate segment together, and the product can be used below 150 degrees Celsius. In today's industrial system, there is an increasing demand for PIR polyurethane panels. Recently, many customers are looking for PIR polyurethane cold storage board, so what is PIR polyurethane cold storage board? Talk to everyone today. The so-called PIR polyurethane cold storage board means that the combustion grade of the polyurethane sandwich panel reaches the B1 level. When it comes to fire rating, I have to mention the old standard GB8624-1997. This is an earlier standard for building fire protection materials. This is described in the standard: Class A: Non-combustible materials (such as rock wool, stone, etc.) Class B1: Flame-retardant materials (such as: polyurethane, polystyrene) Class B2: combustible materials (polyurethane, polystyrene) Class B3: Flammable materials (extruded polystyrene, polyurethane, etc.) Polyurethane is found in B1, B2, and B3 materials. Back to the topic, polyurethane cold storage board, as a better insulation material today, has been widely used in the construction of cold storage in our production and life. Polyurethane materials are materials for agricultural production systems. Only inorganic materials can achieve Class A non-combustibility. We have already mentioned this in previous exchanges. Therefore, the higher combustion level of polyurethane materials can reach B1 level. Question:What is clean room panels made of? Answer:Clean room panel, also known as clean board, is a composite board with color-coated board, stainless steel and other materials as the surface material.

Answer:Ensure the establishment of a scientific and strict sterile pharmaceutical production environment, process, operation and management system. Eliminate biological bacteria and produce high-quality and safe pharmaceutical products. If one link is not well controlled, no matter how good the production process is, no matter how good It is also difficult to ensure the quality of drugs
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.
