Laser processing, as an important technology in modern manufacturing, is widely used in fields such as metal cutting, engraving, and welding. However, the fine particles and aerosols generated during this process pose a potential threat to the health of operators. Therefore, choosing the appropriate protective mask is crucial, and the KN100 mask is one of the recommended protective equipment in laser work environments.
Health risks in laser processing
During laser processing, high temperatures can cause metal or non-metal materials to instantly evaporate or vaporize, producing a large amount of fine smoke, metal vapor, and aerosols. These particles have extremely small particle sizes, typically at the micrometer or even nanometer level, and are highly susceptible to entering the human body through the respiratory tract. Long term inhalation of these harmful substances may lead to respiratory diseases, lung damage, and even increase the risk of cancer. For example, certain metal particles (such as nickel, chromium, etc.) are toxic or carcinogenic, and have a particularly serious impact on health.
The protection principle of KN100 mask
KN100 is a protective mask grade specified in the Chinese national standard GB2626-2019, with a filtration efficiency of over 99.97% for non oily particles. This standard means that KN100 masks can effectively block the vast majority of fine particles, including smoke and aerosols generated during laser processing. In contrast, low-level masks (such as KN95 or KN90) have lower filtration efficiency and cannot provide the same level of protection.
Why choose KN100?
Efficient filtration: The particle size distribution of laser generated particles is wide, with a high proportion of submicron particles. The high-efficiency filter layer of KN100 mask can ensure that these small particles are effectively blocked, reducing the risk of inhalation.
Tight fit: KN100 masks are typically designed to tightly fit the face, preventing particles from leaking through gaps. This is particularly important for laser workers, as any leakage could lead to harmful substances entering the respiratory tract.
Long term protection: For personnel engaged in laser processing for a long time, the protective effect of low-level masks may be insufficient. KN100 masks provide a higher level of protection and help reduce the probability of occupational diseases.
Practical application suggestions
When choosing KN100 masks, the following points should be noted:
Certification standard: Ensure that the mask complies with GB2626-2019 standard and has clear protection level markings.
Usage duration: According to the degree of pollution in the work environment, regularly replace the mask to avoid a decrease in filtration efficiency caused by prolonged use.
Comprehensive protection: Masks are only a part of protection, and laser workplaces should also be equipped with good ventilation systems, local exhaust devices, etc. to comprehensively reduce
