Abstract

Ayuda de molienda con el fin de obtener suspensiones acuosas desustancias minerales refinadas que puedan ser bombeadas, no conduzcan por sí mismas a sedimentación y son altamente concentradas en sustancias minerales, caracterizado porque dicha ayuda de molienda es una sal de ácidos poliaspárticos. Sales de ácido poliaspártico como ayuda de molienda como se reivindicó en la cláusula 1, caracterizadas porque dicha sal tiene un peso molecular promedio expresado como Mw en el rango entre 3500 y 25000 medido mediante GPC acuoso. Sales de ácido poliaspártico como ayuda de molienda como se reivindicó en una de las cláusulas 1 o 2, caracterizadas porque la sal de ácido poliaspártico es hidrolizada y neutralizada mediante al menos un agente hidrolizante y neutralizante que tenga una función monovalente o mediante combinación de al menos un agente hidrolizante o neutralizante que tenga una función monovalente con al menos un agente neutralizante que tenga una función polivalente. Sales de ácido poliaspártico como ayuda de molienda como se reivindicó en cualquiera de las cláusulas 1 a 3, caracterizado porque la sal de ácido poliaspártico es una sal de un homopolímero de ácidos aspárticos. Sales de ácidos poliaspárticos como ayuda de molienda como se reivindicó en cualquiera de las cláusulas 1 a 3, caracterizado porque la sal de ácido poliaspártico es una mezcla de homopolímero de sal de ácido aspártico con una polisuccinimida o una mezcla de homopolímero de sal de ácido aspártico con 5100, de partículas refinadas es menor de 3 micrómetros y preferiblemente menos de un micrómetro. 1Una suspensión acuosa de sustancias minerales como se reivindicó en la cláusula 15, caracterizado porque la sustancia mineral se escoge entre carbonato de calcio natural, carbonato de calcio sintético o dolomitas. 1Una suspensión acuosa de sustancias minerales como se reivindicó en las cláusulas 15 y 16 como relleno para papel y como aplicación de recubrimiento para papel.Grinding aid in order to obtain aqueous suspensions of refined mineral substances that can be pumped, do not by themselves lead to sedimentation and are highly concentrated in mineral substances, characterized in that said grinding aid is a salt of polyaspartic acids. Polyaspartic acid salts as a milling aid as claimed in clause 1, characterized in that said salt has an average molecular weight expressed as Mw in the range between 3500 and 25000 measured by aqueous GPC. Polyaspartic acid salts as a milling aid as claimed in one of clauses 1 or 2, characterized in that the polyaspartic acid salt is hydrolyzed and neutralized by at least one hydrolyzing and neutralizing agent having a monovalent function or by combining at least a hydrolyzing or neutralizing agent having a monovalent function with at least one neutralizing agent having a polyvalent function. Polyaspartic acid salts as a milling aid as claimed in any one of Clauses 1 to 3, characterized in that the polyaspartic acid salt is a salt of a homopolymer of aspartic acids. Polyaspartic acid salts as a milling aid as claimed in any one of Clauses 1 to 3, characterized in that the polyaspartic acid salt is a homopolymer mixture of aspartic acid salt with a polysuccinimide or homopolymer mixture of aspartic acid salt at 5100, the refined particle size is less than 3 microns and preferably less than one micron. 1An aqueous suspension of mineral substances as claimed in clause 15, characterized in that the mineral substance is chosen between natural calcium carbonate, synthetic calcium carbonate or dolomites. 1An aqueous suspension of mineral substances as claimed in clauses 15 and 16 as filler for paper and as a coating application for paper.
