Mask production equipment is mainly classified according to the shape of the mask, and is mainly divided into flat mask production equipment, N95 mask production equipment, folding mask production equipment, duckbill mask production equipment, and different mask production equipment is used for different finished masks.
1. Introduction of ultrasonic mask body machine
Ultrasonic mask body machine, also known as mask punching machine, is a machine used for automatic production of multi-layer material flat masks. It can use 1~4 layers of PP spunbond non-woven activated carbon and filter materials. The entire machine is fed from raw materials. Inserting the nose line, sealing the edge, and cutting the finished product are all automated operations in one line.
Depending on the raw materials used, different standards such as N95, FFP2, etc. can be achieved. Lijin's flat mask production equipment has stable performance, high output, low defect rate and easy operation.
The mask body machine plus several inner ear band mask machines, outer ear band mask machines, bandage mask machines or ear band spot welding machines can produce various types of masks such as inner ear band masks, outer ear band masks, bandage masks, etc.
2. Introduction of folding mask machine
Folding mask machine, also known as C-type mask machine, is a fully automatic machine for the production of folded mask bodies. It uses ultrasonic technology to bond 3 to 5 layers of PP non-woven fabrics, activated carbon and filter materials, and cut out the folded mask body. , Can process 3M 9001, 9002 and other mask bodies.
According to the different raw materials used, the masks produced can reach different standards such as FFP1, FFP2, N95, etc. The ear straps are elastic non-woven fabrics, which make the wearer's ears comfortable and pressure-free. The filter cloth layer of the mask has a good filtering effect and is perfect It fits Asian faces and can be used in high-polluting industries such as construction and mining.
1. Textile Airflow Resistance Tester
The textile airflow resistance tester is mainly used to measure the air penetration resistance of textiles, cotton wool, space cotton, etc. It is one of the important means to identify the comfort and hygiene of clothing, textiles, especially medical textiles.
2. Medical mask synthetic blood penetration tester
A certain amount of synthetic blood is sprayed horizontally to one side of the mask to be tested at a certain pressure and distance, and the penetration of the synthetic blood on the other side of the mask is observed.
3. Medical mask flame retardant performance tester
It is mainly used to test the combustion performance of medical masks after they are exposed to flame at a certain linear speed. It is a special test instrument for the flame retardant performance of medical masks.
4. Digital fabric air permeability tester
It is used to detect the air permeability of various textile materials such as woven fabrics, knitted fabrics, non-woven fabrics, coated fabrics and industrial filter papers under certain pressure.
5. Filter test bench
When it comes to the filter test bench, this is the part I know best, after all, our company produces this product.
The YY 0469-2011 standard stipulates that under the specified conditions, the filtration efficiency of medical surgical masks for Staphylococcus aureus aerosol with an average particle diameter of (3±0.3) μm is not less than 95%, and the filtration efficiency of the air flow (30±2) Under the condition of L/min, the filtration efficiency of sodium chloride aerosol with aerodynamic median diameter (0.24±0.06) μm is not less than 30%.
The N95 mask is one of the 9 types of anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). Under the testing conditions specified by the NIOSH standard, the filtration efficiency reaches at least 95%.
Maybe you see the above content and think that you only need to consider the filtration efficiency when choosing a filter material test bench, which is a big mistake.
Like the production equipment, the filter material test bench also considers the shape of the mask.
Take our L1056 and L1053 filter test benches as examples.
The L1053 three-channel filter material efficiency test bench can test a variety of filter materials, but for masks, only flat masks can be tested.
The L1056 mask filtration performance test bench can be said to be a test bench dedicated to testing masks. It is not only suitable for testing flat masks, but also N95 masks and PM 2.5 masks. (In general, this test bench is not recommended for testing the filtration efficiency of other materials unless necessary.)
Considering that you may not be very familiar with the term "flat mask", I will once again explain to you what is a "flat mask".
Flat masks generally refer to medical surgical masks, disposable activated carbon masks, gauze masks, etc., as shown in Figure 1. Literally, it means that the shape is similar to a tablet.
Before, when many customers inquired about products, they asked which of our two test benches was better and more advanced. In fact, there is no better way to say it, only inappropriate.
And our two filter material test benches, L1056 and L1053, also have different models, 1053 series has L1053, L1053C, L1053U; L1056 has six models: L1056, L1056C, L1056R, L1056R1, L1056E, L1056E1.
If you have to ask which one is better, the editor can only say that the test requirements suitable for the production of masks are the best.
Therefore, when choosing a test bench, be sure to clearly state the requirements, otherwise the bamboo basket will be a waste of water.
