Abstract

La presente inveción se refiere a un método mejorado para formar fibras de de material mineral fundido, que tiene un diámetro promedio de 7 micras o menos, que coprende introducir dicho material fundido en un motor giratorio interno al pared periférica del rotor y pasar el material fundido a través de orificios situados en la pared periférica, cada orificio tiene un diámetro inicial no mayor de unas 457 micras, caracterizados por que se hace pasar el material fundido a través de los orificios para formar fibras primarias con un diámtro promedio menor de 7 micras sin utilizar atenuación por soplado de gas caliente; formar, alrededor pero espaciadas de la pared periférica, una serie de corrientes de gas en movimiento, separadas por una serie de zonas en repeso relativo; mover al gas en las corrientes en una dirección transversal a la dirección del movimiento de las fibras primarias, y pasar las fibras primarias a las zonas en reposo y en contacto con las corrrientes del gas de movimento, las corrientes gaseosas tienen una temperatura menor de 149°C, preferiblemente por debajo de 93°C y especialmente por debajo de 65°C o menor y a una velocidad suficiente para romper las fibras primarias de cierta longitud, pero en forma insuficiente para causar cualquier atenuación significante de las fibras.The present invention relates to an improved method for forming fibers of molten mineral material, having an average diameter of 7 microns or less, which comprises introducing said molten material into a rotary motor internal to the peripheral wall of the rotor and passing the molten material Through holes located in the peripheral wall, each hole has an initial diameter of not more than about 457 microns, characterized in that the molten material is passed through the holes to form primary fibers with an average diameter less than 7 microns without use hot gas blowing attenuation; forming, around but spaced from the peripheral wall, a series of moving gas streams, separated by a series of zones in relative delay; move the gas in the currents in a direction transverse to the direction of movement of the primary fibers, and pass the primary fibers to the zones at rest and in contact with the currents of the moving gas, the gaseous currents have a temperature less than 149 ° C, preferably below 93 ° C, and especially below 65 ° C or less, and at a speed sufficient to break the primary fibers of a certain length, but insufficiently to cause any significant attenuation of the fibers.
