The working principle of air filter masks, or filter masks for short, is to let the air containing harmful substances pass through the filter material of the mask to evolve and then be inhaled.
Air-supply mask refers to a clean air source isolated from harmful substances, which is sent to the face of the person through the catheter to the mask for breathing through power action such as air compressor and compressed gas bottle device.
Filter masks are a widely used category in daily work. The selection methods and conditions of use of such masks are described in detail below. The structure of a filter mask should be divided into two parts, one is the main body of the mask, which can be simply understood as a shelf of the mask; the other is the filter material part, including filter cotton for dust prevention and chemical filtering for antivirus Boxes etc. Therefore, for the selection and use of filter masks, some products produced by Guangjia provide you with the following convenience, that is, you can use the same type of mask body. When dust protection is required in a dust working environment, match it with the corresponding Filter cotton, so you wear a dust mask; when you need to perform anti-virus in a toxic environment, replace the filter cotton and the corresponding chemical filter box on the device, so that it has become a anti-virus mask or according to Your work needs provide you with more combinations.
Brief introduction of the filter material of the mask
The filter materials of protective masks are mainly divided into two categories, namely dust-proof and anti-virus. The role is to absorb harmful aerosols, including dust, smoke, mist, toxic gas and toxic vapor, etc., through the filter material, blocking it from being inhaled by people.
Use of masks
In general, the mask must be of a suitable size and the wearing method must be correct for the mask to be effective. The masks on the market are generally divided into two types, rectangular and cup-shaped. A rectangular mask must have a structure of at least three layers of paper to protect it. The user needs to press the wire on the mask against the bridge of the nose, and then spread the entire mask along the bridge of the nose to show the effectiveness. Let the child wear a rectangular surgical mask because it has no fixed shape, and if it is properly tied, it can fit the child’s face. Cup-shaped masks must ensure that the masks have sufficient density after they are attached to the face, so that the air will not leak out when they are inhaled to be effective. When wearing a cup-shaped mask, cover the mask with both hands and try to blow air. Check whether there is air leakage from the edge of the mask. If the mask is not tight, you must readjust the position and then wear it.
Medical non-woven products are medical and hygienic textiles made of chemical fibers including polyester, polyamide, PTFE, polypropylene, carbon fiber and glass fiber. Including disposable masks, protective clothing, surgical gowns, isolation gowns, lab coats, nurse caps, surgical caps, doctor caps, surgical bags, maternity bags, first aid kits, diapers, pillowcases, bed sheets, duvet covers, shoe covers and other disposable medical consumables . Compared with traditional pure cotton woven medical textiles, medical nonwoven fabrics have the characteristics of high filterability for bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy to compound with other materials. Medical non-woven products, as disposable disposable items, are not only convenient to use, safe and hygienic, but also effectively prevent bacterial infection and iatrogenic cross-infection. In China, the investment in the medical and health industry has reached more than 100 billion yuan, of which the total output value of sanitary products and materials has reached 64 billion yuan, and is developing in a diversified direction.

1. The use of ultrasonic welding eliminates the need for needle thread, saves the trouble of frequent needle thread changes, there is no broken thread joint of traditional thread stitching, and neat local shearing and sealing of textiles. Stitching also plays a decorative role. It has strong adhesion, can achieve waterproof effect, clear embossing, more three-dimensional relief effect on the surface, fast working speed, good product effect and high-end beauty; quality is guaranteed.
Second, the use of ultrasonic and special steel wheel processing, the edge of the seal does not crack, does not hurt the edge of the cloth, and there is no burr, curling phenomenon.
3. No preheating is required during manufacturing, and continuous operation is possible.
Fourth, the operation is simple, not much different from the traditional sewing machine operation method, ordinary sewing workers can operate.
5. Low cost, 5-6 times faster than traditional machine, high efficiency.
1. The mask is contaminated with foreign objects such as blood stains or droplets
2. The user feels that the breathing resistance becomes greater
3. Damaged mask
4. Dust-proof filter cotton, when the mask is close to the user’s face, when the user feels a lot of breathing resistance, it means that the filter cotton is full of dust particles and should be replaced
5. When the anti-virus filter box and the mask are in close contact with the user’s door, when the user smells the poison, it should be replaced with a new mask. The blood circulation of the nasal mucosa is very strong.
Folding mask machine is a fully active machine for the production of folding mask bodies. Using ultrasonic technology, the folding mask machine bonds 3 to 5 layers of PP nonwoven fabric, activated carbon and filter materials, and cuts out the folding mask body, which can be processed 3M9001 , 9002 and other mask bodies.
The folding mask machine is different according to the original materials used, and the masks produced can reach different specifications such as FFP1, FFP2, N95, etc. The ear straps are elastic non-woven fabrics, which make the wearer’s ears comfortable, no pressure, mask filter cloth The layer has a good filtering effect, perfectly conforms to the shape of Asian faces, and can be applied to construction, mining and other highly polluting occupations.
1. PLC active control, active counting by folding mask machine.
2. Simple adjustment equipment for folding mask machine, easy to change materials.
3. The mold adopts the extraction and replacement method. The folding mask machine can quickly replace the mold and produce different types of masks.
4. The folding mask machine is made of aluminum alloy, which is beautiful, sturdy and not rusty.
5. Leading feeding and receiving equipment.
6. The folding mask machine has high stability and low failure rate.
The N95 mask machine reminds you: don’t jam when the N95 mask is taken off. Fold the N95 mask from outside to inside. Be careful not to let your hands touch the inside of the mask when folding it. Pack your tissues or handkerchiefs well for use next time. N95 masks should be cleaned and disinfected every day. Both gauze masks and air filter masks can be disinfected by heating. After washing with clean water, hang in the sun.
N95 masks were born during the special period of “SARS”. They have passed NIOSH certification in the United States and FFP2 certification in Europe. They have a high degree of protection against respiratory infectious diseases. However, N95 masks are thicker, have poor breathable hinges, and have a relatively low wearing comfort. Generally, they are only used when doctors diagnose and treat highly infectious diseases. General protection for healthy people is not necessary. This kind of mask is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). “N” means not suitable for oily particles (oily smoke produced by cooking is oily particulate matter, and the droplets generated by people talking or coughing are not oily); “95” refers to filtering under the test conditions specified by the NIOSH The efficiency reaches 95%. N95 is not a specific product name. As long as it conforms to the N95 standard, and products that pass the NIOSH review can be called “N95” masks
