Title:
多孔質粒子からのガス放出を制限する方法
Document Type and Number:
Japanese Patent JP6889552
Kind Code:
B2
Abstract:
A process is disclosed for limiting the emissions of gases from a porous material in the form of particles comprising a porous inorganic support and at least 0.1% by weight of one or more compounds chosen from organic compounds, halogen compounds, boron compounds and phosphorus compounds. The particles are placed in motion within a hot gas stream traversing them, and a liquid composition containing one or more film-forming polymer(s) is sprayed over the moving particles by means of a twin-fluid atomization nozzle, in which the liquid composition is mixed with a pressurized gas, with a relative atomization pressure of greater than or equal to 0.7×1005 Pa, until a protective layer containing the film-forming polymer(s) and exhibiting a mean thickness of less than or equal to 20 μm is obtained on the surface of the said particles. A material resulting from this process is also disclosed.
