生物安全氣密門
(生物安全充氣式密閉門）
高級別生物安全實驗室建設過程中，氣密性是保證實驗室空氣潔凈度、室內(nèi)實驗人員和室外環(huán)境安全的重要手段。氣密門是具有氣密性要求的高等級生物安全實驗室圍護結構中不可或缺的重要組成部份，廣泛應用于有氣密性要求的房間，以保證實驗室圍護結構的氣密性。生物安全氣密門分為二種，一種為充氣式氣密門，一種為機械壓緊式氣密門。
實驗室防護區(qū)圍護結構的氣密性就達到在關閉受測房間所有通路并維持房間內(nèi)的溫度在設計范圍上限的條件下，當房間內(nèi)的空氣壓力上升到500PA后，20min內(nèi)自然衰減的氣壓小于250PA。房間相對負壓值達到-500Pa,經(jīng)20min自然衰減后，其相對負壓值不應高于-250Pa.
充氣式氣密門主要由門框、門板、充氣密封條，控制系統(tǒng)組成，其中充氣密封條安裝于門頁側面的凹槽內(nèi)。其工作原理為：門開啟時，充氣密封條收縮于凹槽內(nèi)。門關閉時，密封條自動充氣膨脹，使門與門框之間形成嚴格密封，同時門被緊緊鎖緊。
充氣密封式氣密門分為單氣囊和雙氣囊兩種類型，其中雙氣囊充氣密封式氣密門具備現(xiàn)場氣密性自檢測功能。其性能指標包括結構抗壓力、充氣密封膠條的充放氣時間、充放氣次數(shù)、氣密性等。

Biosafety airtight door
(Biosafety inflatable airtight door)
In the construction process of high-level biosafety laboratories, airtightness is an important means to ensure the cleanliness of laboratory air.
1. Structural Pressure Resistance: The door must be able to withstand a certain amount of pressure to prevent any leakage of air or contaminants. The structural pressure resistance should be greater than 2500 Pa.
2. Inflation and Deflation Time: The time it takes for the inflatable sealing strip to inflate or deflate should be within 5 seconds to ensure quick and efficient sealing and unsealing of the door.
3. Inflation and Deflation Frequency: The inflatable sealing strip should be durable enough to withstand a high number of inflation and deflation cycles, typically over 10,000 times.
4. Airtightness: The door should maintain a high level of airtightness, with a leakage rate of less than 0.25% vol/h even under a pressure difference of ±500 Pa.
5. Safety Redundancies: The door should have safety features such as emergency stop buttons and manual deflation valves to prevent the door from being stuck in case of electrical or pneumatic failure.
6. Corrosion Resistance: The door should be constructed from materials that can resist common disinfectants and cleaning agents, ensuring longevity and reliability in a laboratory environment.
7. Locking Mechanis: The door should have a robust locking mechanism, such as an electromagnetic lock, to ensure that it remains securely closed when not in use.
8. Mutual Interlocking: For areas requiring multiple doors, the doors should have an interlocking system to prevent the opening of one door without the proper sequence or conditions being met.
9. Customizability: The door should be customizable to meet specific user requirements, such as integrating access control systems for added security.
10.Self-Testing Function: For double airbag inflatable sealed airtight doors, an on-site airtightness self-testing function is beneficial to ensure the door's performance is maintained.
These features ensure that inflatable airtight doors are not only effective in maintaining the necessary containment conditions within high-level biosafety laboratories but also safe and reliable for the personnel using them. The doors play a critical role in preventing the escape of potentially hazardous biological materials and ensuring the safety of both the laboratory workers and the external environment.
