When buying masks, many people are not sure what are the differences between masks. Ordinary disposable masks and medical disposable masks look very similar in appearance, but they are different. Next we will introduce the difference between them.
Medical disposable masks are commonly used in operating rooms and other environments where there is a risk of body fluids and blood splashing. They are produced by disposable surgical mask making machines. It can effectively block blood and body fluids from passing through the mask to infect the wearers. At the same time, the bacteria filtration efficiency is very high. However, its particle filtration effect is not good, and its rectangular design is not as close to the face as medical protective masks. Common medical disposable masks have several styles such as strap type and ear hook type.
At present, the common masks in the market can be divided into three types: medical disposable masks, medical protective masks and ordinary cotton gauze masks. Among them, medical disposable masks and medical protective masks can block most of the bacteria, and cotton gauze masks can only block a small part of bacteria, so it is recommended to choose the first two masks. If you go to public places and do not come into contact with patients, wearing medical disposable masks is sufficient, there is no need for excessive protection. But if you are in contact with patients, you must wear bio-resistant medical protective masks. They are produced by professional surgical mask making machines.
Ordinary disposable masks are fiber masks, which are a mechanical barrier. Large particles can be blocked by layers, but particles smaller than 5 microns in diameter cannot be blocked, let alone PM2.5 particles, but disposable medical masks can block particles larger than 4 microns in diameter, so we need to wear 16 layers ordinary masks to achieve the same protective effect as medical masks. In addition to relatively high hygiene requirements, disposable medical masks should also have the function of effectively blocking liquid splashes. This is because during the operation, there is the possibility of blood or infectious body fluid splashing. This kind of splashing has a certain pressure and is not a normal liquid immersion. The material of medical masks should have a relatively high ability to block pressured liquids. Only in this way can the health and safety of medical staff be effectively protected.
In addition, ordinary disposable masks and medical disposable masks have the following differences.
Disposable masks are made of two layers with 28 grams of non-woven fabric. Medical disposable masks are mostly made of one or more layers of non-woven fabrics with disposable mask making machines.
The main production processes of medical disposable masks include meltblown, spunbond, hot air or needle punch, etc., which are equivalent to resisting liquids, filtering particles and bacteria, and are a kind of medical protective textiles. The realization of these processes requires a combined operation of different mask making machines.
Under the condition of air flow rate (85±2) L/min, the medical disposable mask has a filtration efficiency of not less than 95% for the median aerodynamic diameter (0.24±0.06) μm sodium chloride aerosol. It can block airborne infectious agents with a diameter of <5μm or close contact with infectious agents transmitted by droplets.
Through the above introduction to the ordinary disposable masks and medical disposable masks, we know the differences between different types of masks and they are produced by different automatic mask making machines. If you want to entry the mask industry, you need to purchase professional high speed mask making machines.
Urban mainly develops and produces all kinds of machines, including medical mask making machines, capsule filling machines, food packaging machines, pharmaceutical packaging machines, etc. If you need, we can provide you with high-quality products and services.
