What negative impact does a tiny air leakage from the filter paper have on the air filter?
What negative impact does a tiny air leakage from the filter paper have on the air filter?Answer: The filter paper has fluff and damage, which causes tiny air leakage, which will seriously affect the filter efficiency and airflow quality of the filter, bring unnecessary trouble and burden to the production workshop, clean workbench, and clean room, and hinder the entire production process.Are there any cleanliness standards for suspended particles in clean rooms, and what is the level basis? What method should be used to increase the indoor ventilation volume and improve cleanliness when the size and number of the existing air supply ports cannot be changed? Answer: To increase the indoor ventilation volume and improve the cleanliness, the width, height, depth, etc. of the filter can be determined according to the customer's requirements (initial resistance, surface wind speed, rated air volume) and other relevant data. If it is impossible to change the size and number of the existing air supply ports, the filter thickness can be increased. For example: 610*610*120 can be replaced by a 610*610*292 type filter. What are the advantages and benefits of glass fiber filter paper? Answer: Glass fiber paper is chosen because it has extremely high filtration efficiency, good chemical stability, and low resistance, making it the preferred material for high-efficiency and especially ultra-high-efficiency air filters. Glass fiber paper can be used to make air filters with and without partitions, and is suitable for air clean room applications in various fields from primary efficiency, medium efficiency, high efficiency to ultra-high efficiency. What should be paid attention to when installing and using filters? Answer: Due to the unique brittleness of glass fiber paper, the first thing to consider during use and installation is not to contact with sharp objects and repeated rubbing. Secondly, glass fiber paper should be kept in contact with water or other corrosive liquids as little as possible during use to avoid affecting its normal use. Clean workshops are required to have good clean equipment. Thirdly, the reasonable use of coarse, medium, and high-efficiency filters ensures that each filter does not bear too heavy a dust load. Then, before installation, visually inspect the appearance of the filter paper and the filter for damage, and after installation, inspect the sealing condition and strictly check for leaks. (Refer to www.bacclean.com) What is an air shower room? What is the role of an air shower room? Answer: The air/cargo shower room can remove dust attached to the surface of people and objects, reduce the amount of dust brought into the clean air, and also play the role of a lock chamber to prevent unclean air from invading through the door, to cooperate with the clean air conditioning system to ensure that the clean room reaches the required cleanliness. What are the oil mist method and sodium flame method? Answer: The sodium flame method refers to testing the efficiency of the high-efficiency filter by using a dust particle counter to detect the number of sodium chloride droplets before and after the filter. The oil mist method involves passing the oil mist aerosol through the tested filter and using the turbidity method to measure the oil mist concentration before and after the filter to obtain the filter's efficiency. What are the benefits of using multiple filters with primary, medium, and high-efficiency filters? Answer: The reasonable use of primary, medium, and high-efficiency filters ensures that each filter does not bear too heavy a dust load. What are the similarities and differences between the sealing strips currently used by our company and those of the purchased samples? Answer: Our company has 3 kinds of sealing strips. The current sealing strips have rough edges on the upper and lower sides, the color is not bright, and it is not smooth. It is easy to deform when pressed, and the recovery performance is poor. It is disposable. The purchased non-partitioned sample sealing strips are injection-molded seamless strips. They have good elasticity and recovery performance, especially good sealing performance, which can meet customer requirements and standards. The peripheral frame of the test bench in the clean room and the ventilation system duct have air leakage and poor sealing. What consequences will this cause? Answer: A standard ventilation system must be tight, and the sealing of its joints can be tested by the soap bubble method. Similarly, a standard test bench frame must be kept airtight, otherwise it will affect the resistance of the filter, rated air volume, wind speed, resistance of the air inlet filter, air duct resistance, air supply system air supply test, maximum resistance test of the tested filter, resistance test of the air volume measuring device, etc. The relevant parameters and data will be inaccurate. When making filters, what issues should be paid attention to in the selection of filter materials? Answer: The following points should be noted when choosing filter media: A. The larger the effective area, that is, the larger the use area of the filter paper, the larger the dust holding capacity and the smaller the resistance. The longer the service life, of course, the higher the cost; the finer the fiber diameter, the better the interception effect, and the higher the filtration efficiency; the higher the binder content in the paper, the higher the tensile strength of the paper, the higher the filtration efficiency, the less hair removal, the less dust accumulation in the filter material, and the better the water resistance, but the resistance also increases accordingly. |
