What material is suitable for the louver vents in clean rooms?
What material is suitable for the louver vents in clean rooms?For clean rooms of various scenarios, the air supply box is an indispensable ventilation equipment. However, during use, the air supply box may be abnormal due to the inhalation of foreign matter; at this time, many users will equip it with louver vents. The material of the louver is an important reference point. There are two main types, steel and aluminum alloy. In this article, Foshan Zhongjing will provide key considerations for choosing suitable stainless steel louvers.First, the purity of the stainless steel material is one of the key factors. Usually, 304 and 316 stainless steel are more common choices. 304 stainless steel contains 18% chromium and 8% nickel, has good corrosion and heat resistance, and can maintain stable performance in most conventional clean-room environments. For some special clean rooms with higher corrosion requirements, such as places that may be exposed to chemical reagents or high-salt environments, 316 stainless steel is more suitable. 316 stainless steel adds 2% to 3% molybdenum based on 304, which greatly enhances its corrosion resistance, especially its resistance to chloride ions. Surface treatment also has a significant impact on the performance of stainless steel blinds. Mirror-polished or electro-polished surfaces can greatly reduce the adhesion of dust and microorganisms. The smooth mirror-like surface not only makes it difficult for contaminants to gain a foothold but also makes it easy to remove stubborn stains during the cleaning process, keeping the blinds clean. This fine surface treatment helps to reduce the generation and accumulation of particles, ensuring that the air delivered is pure and pollution-free. Welding quality is a detail that cannot be ignored. High-quality welding processes can ensure that the welds are uniform and strong, without defects such as pores and slag inclusions. These defects can become a hiding place for contaminants and are difficult to clean thoroughly, thus affecting the air quality of the clean room. Therefore, when choosing stainless steel blinds, carefully check the welds to ensure that they meet high-quality standards. Sealing is an important line of defense to ensure the quality of clean room air. The structural design of stainless steel blinds should be able to fit tightly to prevent air leakage and the intrusion of external contaminants. Any tiny gaps may allow untreated air to enter the clean room and destroy the clean environment inside it. Strength and durability must also be considered. Cleanrooms require frequent cleaning and disinfection operations. Stainless steel materials should have sufficient strength to withstand these frequent treatments and not be easily deformed or damaged during long-term use. Otherwise, once the shutters are deformed or damaged, it will not only affect the air supply effect but may also generate additional pollution sources. Cleaning convenience is essential to maintain the long-term stable operation of the cleanroom. The structure of the shutters should be easy to disassemble and install so that comprehensive and in-depth cleaning and disinfection can be carried out. Complex structures may cause cleaning dead corners, increase cleaning difficulty, and thus affect the cleanliness of the cleanroom. Choosing suppliers with a good reputation and rich experience is also the key to success. They can provide products that meet industry standards and quality requirements and can provide technical support and service guarantees after sales. At the same time, suppliers are required to provide relevant certification and test reports of materials, such as material composition analysis, surface roughness detection, corrosion resistance test, etc., which can help us further confirm the quality and performance of the selected stainless steel shutters. In summary, the selection of stainless steel shutters suitable for cleanrooms requires comprehensive consideration of multiple factors such as material purity, surface treatment, welding quality, sealing, strength and durability, cleaning convenience, and supplier reputation. |
