• Use of ffp3 respirator
  1. The purpose is to prevent or reduce the dust in the air from entering the respiratory organs of the human body so as to protect the safety of personal protective equipment;
  2. Materials: most of the anti particle masks are made of two layers of non-woven fabric inside and outside, and one layer of filter cloth (melt blown fabric) in the middle;

  3. Filtering principle: the filter cloth in the middle is mainly used to filter the micro dust. Due to the electrostatic characteristics of the melt blown cloth, it can adsorb small particles actively. Since the micro dust is adsorbed on the filter element, and the filter element is static and cannot be washed by water, the self-priming filter type particle respirator needs to replace the filter element regularly

  4. Note: the international requirements for the use of anti particle masks are quite strict. The anti particle masks belong to the first level in personal protective equipment, higher than earmuffs and goggles. The more authoritative testing certification includes CE certification in Europe and NIOSH certification in the United States, while the Chinese standard is similar to NIOSH certification in the United States

  5. Protection object: the protection object is divided into KP and kn. The so-called KP is able to protect oil and non oil particles, while kn is only able to protect non oil particles

  6. Protection level: China's protection level is divided into kp100, kp95, kp90 and kn100, kn95, Kn90. Among them, kp100 and kn100 have the highest filtration efficiency required by the national standard of more than 99.97%, so they have the highest safety for use. different filter materials. On the one hand, the filtration effect is related to the particle size, and also affected by whether the particles contain oil or not. Ffp3 type masks are usually classified according to filtration efficiency and whether they are suitable for filtration of oily particles. Oil free particles such as dust, water-based fog, paint fog, oil-free smoke (welding smoke), microorganism, etc. Although the filter materials of "non oil particles" are common, they are not suitable for oil particles, such as oil mist, oil smoke, asphalt smoke, coke oven smoke, etc. The filter material suitable for oil particles can also be used for non oil particles.

• 1. Disposable anti particle mask: alias: "disposable ffp3 type mask", this kind of anti particle mask is suitable for short-term use in polluted environment,

  
  

  2、半面罩:别名:"FFP3类别口罩""防尘面罩""防尘面具"带呼气阀设计，减少热量积聚，使呼吸更轻松，适合高温、高湿度环境下长时间使用采用无毒、无味、无过敏、无刺激的原材料。高滤效、低阻力可调节鼻夹，使口罩与脸部的密闭性更好，粉尘不能轻易漏入经过静电处理的过滤层，有效地隔滤和吸附极细微的有害工业粉尘，防止矽肺病超音波焊接，氨纶丝材料的松紧带对佩戴者更有效地保护应用:建筑业、农业畜牧业、食品加工业、水泥厂、纺织厂、切割粉尘、重金属有害污染物作业场所。

  2. Semi mask: alias: "ffp3 type mask", "dust mask", "dust mask" with exhalation valve design, reduce heat accumulation, make breathing easier, suitable for long-term use in high temperature and high humidity environment with non-toxic, tasteless, non allergic, non irritating raw materials. High filtering efficiency and low resistance adjustable nose clip make the mask and face more airtight. The dust can not easily leak into the filter layer treated by static electricity. It can effectively filter and absorb extremely fine harmful industrial dust, prevent the ultrasonic welding of silicosis. The elastic belt of spandex material can protect the wearer more effectively: construction industry, agriculture and animal husbandry, food processing industry, cement factory Textile mills, cutting dust, heavy metal hazardous pollutant workplaces.

   

  3. Full face shield: alias: dust proof full face shield, yes and use in special environment

• The elastic belt of spandex material can protect the wearer more effectively: construction industry, agriculture and animal husbandry, food processing industry, cement factory Textile mills, cutting dust, heavy metal hazardous pollutant workplaces.
