392 results about "Oxygen absorption" patented technology

Oxygen absorption in the body (in %) or the efficiency of extraction of oxygen from air is 5.6% (left in the lungs) divided by 20.9% (total oxygen in outer air). The result is about 27%. Hence, people with normal breathing parameters retain about a quarter of the oxygen, the remaining three quarters are exhaled back.

Preparation method for multiphase gel foam for controlling coal autogeneous combustion

InactiveCN101265811AGive full play to the function of suffocation prevention and fire extinguishingIncrease stickinessDust removalFire preventionSpontaneous combustionSlurry
The invention relates to a preparation method of multi-phase gel foam for controlling the spontaneous combustion of coal. The multi-phase gel foam with multiple components of medium is made by adding a slight amount of thickener into the fly ash or the yellow mud slurry to form thickening mud with certain viscosity, adding certain amount of cross-linking agent and foaming agent into the thickening mud, and introducing nitrogen to carry out the physical and mechanical foaming. The bubble wall of the multi-phase gel foam has high viscosity and good elasticity, the fly ash or yellow mud adhere to the bubble wall, and the bubble is internally covered with nitrogen. The multi-phase gel foam is delivered to the mined-out area through the grouting pipeline of the mine, evenly covers the float coal in the mined-out area, and blocks the fractures of the coal body. The method can effectively hinder the oxygen absorption for goal and prevent the oxidization of the coal. The preparation method is simple, and the prepared multi-phase gel foam has low cost and significant effects on fire prevention and extinguishing; the preparation method does not only have the advantages of mud injection, nitrogen injection, two-phase foam injection, gel injection and composite gel injection on fire prevention and extinguishing, and also overcomes the deficiency, which has wide practicality.
