● Research and development background of medical protective masks

Recently, because of the influence of new pneumonia, masks have become the most popular single product. However, due to the influence of the situation, masks have become routine equipment in life. There are two kinds of common medical masks on the market: medical surgical masks and medical protective masks

The medical surgical mask is mainly used in medical outpatient, laboratory, operating room and other highly demanding medical environment. It can block particles larger than 4 microns in diameter, and can block about 70% of bacteria and viruses. However, it does not fit the face well enough, which affects the tightness between the mask and cheek and makes its protective function worse. The medical protective mask and facial fit is better than surgical mask, medical protective mask is mainly used for serious environmental pollution or sudden medical transmission

When infected with diseases (such as respiratory infectious diseases), the safety factor is much higher than that of surgical masks. It can prevent airborne infectious factors with a diameter of ≤ 5 μ mg or close contact (≤ 1m) with diseases transmitted by droplets, and can filter 95% of viruses and bacteria. It is better to prevent New Coronavirus infection and wear medical masks.

● Advantages of medical protective masks

When wearing the ordinary medical protective mask, we often feel that the breathing is not smooth. However, the ventilation resistance of the medical protective mask developed and produced by us is lower than that of the national standard The water electret meltblown cloth is used to make the barrier efficiency more stable. After hundreds of experiments, a most reliable formula is obtained, which can make the meltblown cloth have bacteriostatic function. The particle filtration efficiency can reach more than 95%, and the ventilation resistance is stable below 80pa, After the mask is made, the adjacent non-woven fabric, hot air cotton and the middle melt blown fabric are more closely bonded, so as to achieve the effect of reducing respiratory resistance.
