In the construction process of a high-level biosafety laboratory, it is important to ensure air tightness, which is not only related to the cleanliness of the air inside the laboratory, but also directly related to the safety of laboratory personnel and the safety of the external environment. As a key component in maintaining the airtightness of the room, the design and construction of biosafety air tight doors must strictly follow professional standards.
According to the General Requirements for Laboratory Biosafety GB19489-2008 and the Technical Code for Biosafety Laboratory Construction GB50346-2011, there are clear test standards and methods for the air tightness of each area of the high-level biosafety laboratory. Among them, the test methods are mainly divided into two categories: constant pressure method and pressure attenuation method to ensure that the air tight door can effectively prevent air circulation when closed. In the four-level laboratory protection area that has been built in China, the inflatable air tight door has been widely used because of its excellent performance. At the same time, some laboratories also use mechanical compression airtight doors, both of which can meet the requirements of the air tightness test of the enclosure pressure attenuation method. In the protection area of the three-level biosafety laboratory for large animals, the mechanical compression air tight door is more common, which can meet the requirements of the airtightness test of the constant pressure method of the enclosure structure. In summary, the design and construction of airtight doors occupy a pivotal position in high-level biosafety laboratories. Only by choosing an airtight door that meets national standards and passing rigorous testing can we ensure the safe operation of the laboratory.
Advantages over other products
At present, cleanrooms mainly rely on general clean airtight doors, which are achieved by installing a sealing strip on the door page or door frame and squeezing the sealing strip when closed. However, this form of sealing tends to leak when faced with pressure in the room, especially in the four corners and bottom area of the door. For the high cleanliness requirements of P3 and P4 levels and the occasions that require strict sealing such as pharmaceutical factories, this traditional sealing method obviously cannot meet the needs.
In response to this challenge, our company specially organized a team of professional technicians and production personnel to conduct an in-depth study of various airtight doors. On this basis, we have succeeded in developing the Biosafety Air Tight Door, an innovative product designed to meet high cleanliness and stringent sealing requirements. In the field of biosafety, the issue is not only the personal health of laboratory workers, but also the potential impact of an accident in a highly clean area can be far greater than expected, causing immeasurable harm to people, animals and even plants.
Compared with traditional products, bio-airtight doors have shown significant advantages in many aspects. First of all, in terms of airtightness, the bio-airtight door uses advanced sealing technologies and materials, such as inflatable sealing strips or mechanical compression sealing structures, to ensure that extremely high airtightness standards can be achieved in any working condition. This characteristic makes the bio-airtight door excellent in preventing the spread of pollutants such as microorganisms and harmful gases, which is far superior to ordinary door products.
Secondly, the bio-airtight door is designed with durability and ease of maintenance in mind. Its key components such as door frames and door panels are mostly made of corrosion-resistant and high-strength materials such as stainless steel, which can effectively resist the erosion of various chemical reagents and prolong the service life. At the same time, the simple structural design and easy-to-disassemble components make the bio-airtight door more convenient to maintain and reduce the cost of use.
Unique features
The unique characteristics of the bio-hermetic door are mainly reflected in the following aspects:
Efficient isolation: Through airtight sealing technology and efficient filtration system, the Biosafety Air Tight Door can prevent microorganisms, harmful gases and other pollutants from flowing freely on both sides of the door, effectively preventing cross-infection. This is essential for laboratories, hospitals, pharmaceutical plants, and more.
Strong safety: The Biosafety Air Tight Door not only has excellent sealing performance, but also has high structural strength and stability, which can resist strong winds and external collisions to ensure the safety and reliability of the door. In addition, some bio-airtight doors are equipped with safety devices such as safety sensors and emergency release valves to further enhance the safety of use.
Easy to clean: The Biosafety Air Tight Door is mostly made of easy-to-clean materials such as stainless steel, with a smooth surface and no gaps, which reduces the possibility of dirt and dirt. At the same time, some door types also have a detachable design, which is convenient for users to carry out deep cleaning and maintenance.
Biosafety Air Tight Doors also excel in terms of performance:
Good air tightness: Whether it is an inflatable airtight door or a mechanically pressed airtight door, it can form a strict seal in the closed state to ensure the safety and stability of the indoor environment.
Strong sound insulation: The design of the bio-airtight door fully considers the sound insulation needs, and adopts a multi-layer composite structure and high-density sound insulation materials, which effectively reduces noise interference and provides a quieter working environment for patients and experimenters.
Fireproof and antibacterial: Some Biosafety Air Tight Doors also have fireproof and antibacterial functions. The surface material of the door panel is made of thermosetting high-density resin and other environmentally friendly materials, which not only has strong wear resistance and high fire rating, but also has certain antibacterial properties, which further improves the safety of the door.
High degree of automation: modern Biosafety Air Tight Doors mostly use motor drive and intelligent control system to achieve automatic opening and closing operation, which not only improves the efficiency and convenience of use, but also reduces the risk and labor intensity of manual operation.
Conclusion
As a highly specialized equipment, Biosafety Air Tight Doors play an irreplaceable and important role in the fields of biological science, medical treatment, pharmaceuticals and food production. Its high isolation, high safety, ease of cleaning and excellent performance make Biosafety Air Tight Doors an indispensable key barrier in these areas. With the continuous progress of science and technology and the continuous improvement of market demand, the technology and application of Biosafety Air Tight Doors will continue to innovate and improve, contributing to the safety and security of more fields.
