Guangdong Shenpu Technology Co., Ltd. was established on February 25, 2020, and its registered place is located in Chang'an Town, Dongguan City, Guangdong Province. As a professional China Mask manufacturers and China Mask suppliers, we are strong strength and complete management. Respirator is a kind of sanitary products, generally refers to the mouth and nose is used to filter the air entering the nose and mouth, in order to achieve the role of blocking harmful gases, odors, droplets, viruses and other substances, made of gauze or paper.

Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent and when working in a polluted environment such as dust, wearing a mask has a very good effect.

N series: no time limit for protection of non-oily suspended particles

R series: Protect non-oily suspended particles and sweaty oily suspended particles for a period of eight hours

P series: no time limit for protection of non-oily suspended particles and sweaty oily suspended particles

When the carrier of some particulates is oily, and these substances are attached to the electrostatic non-woven fabric, the electrical properties will be reduced, and the fine dust will penetrate. Therefore, the filter material for preventing the oil and gas sol should undergo special electrostatic treatment to prevent the fineness. The purpose of dust. So each series is divided into 3 levels: 95%, 99%, 99.97% (that is, referred to as 95, 99, 100), so there are 9 small categories of filter materials.

From the point of view of human physiology, blood circulation in the nasal mucosa is very strong, the channels in the nasal cavity are very tortuous, and the nasal hairs constitute a filtering "barrier". When air is sucked into the nostrils, the airflow forms a vortex in the tortuous channel, which heats the airflow sucked into the nasal cavity. Some tests have shown that when cold air at minus 7°C is drawn into the lungs through the nasal cavity, the airflow has been heated to 28.8°C, which is very close to the temperature of the human body. If you wear a mask for a long time, the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity, so you cannot wear a mask for a long time. Masks can only be worn in special environments, such as places with many people and no air circulation. Of course, it is necessary to wear a mask to walk in the wild to resist wind and sand, or to move in an environment with air pollution, but the time should not be too long. In addition, in the flu season, go to public places where a large number of pathogens may exist, you should also wear a mask. Wearing a mask is only one of the ways to prevent respiratory infectious diseases. The most important thing is to maintain good living habits.
