Is the water mill dust in marble stone factory big?

When marble is cut with water, the environment is also filled with water mist. In fact, water mist also contains dust, but dust and water mist are mixed together, and the particles are large, which are generally captured by nasal cavity and throat mucosa. It is rarely inhaled into the lungs.

For the sake of health, it is recommended to wear a composite half-face dust mask in this environment.

Scientific selection of dust mask certified by GB2626-2006 standard is helpful to prevent lung injury.

1, select the composite half mask type. Disposable masks have high air leakage rate and are not suitable for long-term protection.

2. Choose KN 100 dustproof filter cotton for use. Low protection rate will lead to physical injury.

3, the choice of silicone material is more comfortable. Suitable for long-term wear, not easy to cause allergic reactions. A mask with high hardness is easy to cause facial depression.

4. The size of the mask is extremely important. Don't buy those so-called universal masks. Easy to leak.

The mask covers the nose and mouth, and covers the nose, mouth and chin. Suggest using the latter, which is relatively comfortable.

6. It is recommended to choose a mask with smooth breathing. Some masks are designed with double filter cotton, and the filter cotton has two sides, which makes the mask breathe relatively smoothly. At present, some KN 100 masks in China are used in high dust environment, and the average cost is about 1 yuan, which can be borne by both enterprises and individuals.
