One Mode of the invention discloses a Particle flowing freely to be used as an Additive of Foundry Sand,The couple Ticula - including two or more particles of Additives are na of different castings, being attached to each other Additives of different casting Sand,Through the use of a Binder Additive.Another form of the invention is a mixture of Rena comprising a casting Sand and parti - Additive particles that Flow freelyWhere The Additive free flowing particles comprise at least two different additives linked together by a Binder Additive.An additional form of the invention is a process for introducing Additives into a Sand Fun Edition,The process includes providing at least two Additives of Foundry Sand di.erent together using a Binder additive for obtaining particles flowing freely between com poA least two Additives of different condition of Sand Fun, Introducing the particles flowing freely in a Foundry Sand.Yet an additional Mode of the invention is a method to control the PH of two additives nadidos - a mixture of Sand castingCOM on the steps of the method provide an Additive of Foundry Sand that has a pH lower than the ma yor or neutralAnd covering at least part of the Additive with a po limerico material that has a pH neutral.Another form of the invention is a method for Controlling the particle size and size distribution of the Additive,To eliminate the problems associated with particles finely LIVIDI - dasSuch as the tendency to generate Fine Powder and the tendency to reduce significantly in recent years. - The Resistance of the core or Mold casting manufactured containing the Additive.Yet another form of the invention is to provide a method for introducing the Additives to control the thermal expansion or Nuclei mol - des,It is more effective to control the expan - sion that the use of Additives - linked indivi Dually.
