To know the bulk density or bulk density of dust, that is, the weight of dust per unit volume. The unit volume includes the volume of the dust particles, the pores of the dust particles adsorbed on the surface of the dust particles, the air volume, and the gap between the dust particles. Knowing the bulk density of the dust and the characteristics of the bag filter are important for ventilation and dust removal because it is closely related to the dust removal performance of the dust.
Chemical and physical properties of dust-laden gas, such as moisture content, temperature, chemical composition, and properties. The determination of these parameters has a direct and indirect relationship with the selection of additional dust removal measures and the selection of the filtering wind speed. Dust-laden gases, if any, contain chemical components such as chlorides, and chlorides are generally susceptible to “suck moisture.†If no additional measures are taken, dust bags may “paste bagsâ€.
Dust particle size distribution. The particle size of dust is its basic characteristic. It is a composition composed of particles of various particle sizes. It is not sufficient to simply characterize such aggregates by the average particle size.
Dust stickiness. Viscosity is a characteristic of the mutual attraction between dust or dust and the molecules on the surface of the object. The effect of stickiness on the bag filter is even more pronounced because the dust collection efficiency and the filter resistance largely depend on the ability to remove dust from the filter media.

1, the selection of goggles should be selected by the product inspection agency inspection of qualified products;
2. The width and size of the goggles should suit the user's face shape;
3, lens wear rough, lens frame damage, will affect the vision of the operator, should be replaced in time;
4. Goggles should be specially used to prevent eye diseases;
5, the filter and protection of welding goggles should be selected and replaced according to the requirements of the specified operation;
6. Prevent heavy fall and heavy pressure, and prevent hard objects from rubbing lenses and masks.
Two types of use of safety protective glasses:
A. Anti-cementing debris
Mainly used to prevent metal or sand debris and other mechanical damage to the eyes. Lenses and frames should be of solid construction and resistant to impact. The frame of TDAF001 sky shield is equipped with a shielding edge, and there shall be ventilation holes on it. Protective lens can choose toughened glass, adhesive glass or copper wire mesh protective lens.
B. Antichemical solution
Mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lens can be used, and the frame should be covered to prevent the solution from splashing into. Usually used in laboratories, hospitals and other places, general medical glasses can be universal
