b: > >Use of anti-shock wave sealed door:
>

> Anti-shock wave sealed doors are mainly used in underground blasting material warehouses and blasting material distribution chambers in mines. They can effectively prevent flames, smoke, and toxic gases caused by explosive explosions from spreading outwards, resist shock waves, and adjust the ventilation required in the warehouse. If there is a fire in the warehouse, close the ventilation holes for isolation.
