3.1 Block explosion suppression materials
Mesh or other shaped materials made of special alloys filled with flammable liquids and flammable gas tanks to block fire
Flame spread to prevent the explosion, so as to achieve safety requirements.
3.2 Blocking blasting material sheets
In line with the requirements of the material to block the explosion suppression materials processed by a certain process after the formation of the film did not start.
3.3 Block explosion suppression materials units
In accordance with the requirements of the use of the barrier explosion suppression materials developed after the sheet, stacked together to form a certain thickness or number of honeycomb structure of the material.
3.4 Cell cel
Barrier pop suppression material lateral expansion, the formation of uniform hexagonal openings.
3.5 Number of cells celcount
After the explosion suppression material sheet is expanded, the number of holes per unit area that meets the requirements is generally the number of holes on an area of 100 cm 2.
3.6 Replacement rate fueldisplacingrate
