At 6:30 in the morning, the buzzing of the cutting machine sounded in the workshop on time. Every contact between the blade and the marble raises a fine layer of stone powder, like a silent mist under the light. The air you inhale every day contains invisible silica particles - they are small but may slowly affect the elasticity of the lungs.
However, there's no need to be nervous, the protective measures are practical. The dust concentration varies greatly in different work environments. Fangdun's dust masks comply with the national standard GB 2626-2019. You can refer to it as follows:
If you have been cutting and trimming continuously all morning and have dense dust, it is recommended to upgrade to KN95 level. The filtration efficiency of KN95 is not less than 95%, making it a reliable partner for routine operations.
If it is in a relatively closed corner or subjected to high-intensity polishing for a long time with high dust concentration, then choose KN100 grade. The filtration efficiency of KN100 is not less than 99.97%, which is almost the highest level of protection, allowing you to have more confidence in heavy dust environments.
Ordinary cotton masks or medical masks have large gaps that cannot block fine stone powder, so there is no need to consider them.
The small movements of wearing determine the big effect
No matter how good the mask itself is, if it is not worn tightly, it is useless. After wearing the mask each time, gently cover the edge of the mask with your palm and exhale forcefully - feel if there is any air leakage around the nose bridge and chin. Adjust the nose clip to fit the shape of the nose; If you grow a beard, the fit will be compromised, so try to trim it in advance. Fangdun's three-dimensional cutting and adjustable nose clip are designed to help you fit your face more easily.
Replace it if necessary, don't let it exceed its service life
Dust masks are not permanent equipment. The filter layer cannot be washed with water or wiped with alcohol. In high dust environments, if you feel a significant increase in respiratory resistance or if the inside of your mask is covered in dirt, replace it promptly. For the half face mask with replaceable filter cotton, the filter cotton should also be replaced regularly and cannot be cleaned or reused.
Every cutting, dust is flying; But every time you wear a mask correctly, you are fighting for a cleaner breath for yourself. Open a wet cutting process and let the water mist press down on the stone chips. Combined with protection, it provides double protection and is both practical and simple. After finishing a day's work, take off your mask and keep it fresh inside - this is probably the best way to take care of yourself.
