How Do Medical Masks Build a Safety Fortress with Technological Power

1. As a key piece of equipment in the field of medical protection, medical masks are an important barrier to safeguard public health. They mainly consist of three layers. The outer layer is hydrophobic non - woven fabric, which can effectively block splashing droplets. The middle layer, the melt - blown fabric, is the core filtration layer. Through the electrostatic electret process, it can efficiently adsorb and filter bacteria, viruses, and fine particulate matter in the air. The inner layer is made of skin - friendly non - woven fabric, which is soft and breathable, avoiding discomfort caused by direct contact with facial skin.

2. According to the protection level and application scenarios, medical masks can be divided into medical protective masks, medical surgical masks, and general medical masks. Medical protective masks meet the GB19083 - 2010 standard, are suitable for high - risk environments, and can filter at least 95% of non - oily particulate matter. Medical surgical masks comply with the YY0469 - 2011 standard, are mainly used in scenarios such as clinical surgeries, and focus on splash prevention and bacterial filtration. General medical masks meet the basic hygiene protection requirements and are mostly used in general medical environments or for daily protection.

Ultrasonic welding uses seamless fusion to reinforce the "safety line" of the mask's protective performance.

3. In terms of quality assurance, the seamless fusion effect formed by ultrasonic welding has significant advantages. Verified by a third - party testing agency, the tensile strength of the mask ear straps welded by this technology is increased by 40%, and the edge sealing is enhanced, effectively reducing the risk of bacteria and droplet leakage, fully meeting the YY0469 - 2011 medical surgical mask standard and the GB19083 - 2010 technical requirements for medical protective masks. A quality inspection engineer said, "Ultrasonic welding has no针眼 and gaps, and the melt - blown fabric filtration layer will not reduce its protective performance due to high temperatures or mechanical damage, which is crucial for the safety of medical masks."
