Abstract

On fait mousser le plâtre avec un agent porogène, puis on le coule ou on le transforme d'une autre manière. On forme une mousse avec de l'eau, de l'air et un agent porogène et cette mousse est introduite sous pression dans le mortier de plâtre. L'installation employée comprend un dispositif malaxeur 13, 21 pour former le mortier de plâtre par mélange de plâtre et d'eau, un dispositif transporteur 21 pour le mortier de plâtre, raccordé au dispositif malaxeur 13, 21 et un générateur de mousse 40 relié au dispositif transporteur 21 pour mélanger de l'eau contenant un agent porogène avec de l'air, afin de produire la mousse. Application du plâtre cellulaire : isolation notamment d'armoires à documents à l'épreuve du feu.The plaster is foamed with a blowing agent, then it is cast or otherwise processed. A foam is formed with water, air and a blowing agent and this foam is introduced under pressure into the plaster mortar. The installation employed comprises a mixing device 13, 21 for forming the plaster mortar by mixing plaster and water, a conveyor device 21 for the plaster mortar, connected to the mixing device 13, 21 and a foam generator 40 connected to the conveyor device 21 for mixing water containing a pore-forming agent with air, in order to produce the foam. Application of cellular plaster: insulation in particular of fireproof document cabinets.
