SOLID DISPERSED ABRASIVE COMPOSITIONS AND A METHOD OF PRODUCTION OF LIQUID ABRASIVE CLEARING COMPOSITIONS Russian patent published in 2005 - IPC

FIELD: clearing of solid surfaces.

SUBSTANCE: the invention is pertaining to the field of utilization of solid dispersed abrasive compositions for clearing solid surfaces. The dry composition contains a solid material abrasive and a suspending system eligible for production of a stable suspension at mixing with a liquid medium. It is preferable, that the dry composition should contain at least 65 % of solid abrasive and at least 0.1 % of a suspending system. The suitable suspending systems are based on a surfactant or a mixture of surfactants, which are capable to form a laminated micellar phase after mixing with a liquid medium, or on the basis of polymeric infilling systems. A preferential liquid medium is water. The dry abrasive composition is easily flowing and is easily dispersed in water by a consumer with formation of a liquid clearing composition ready for use.

EFFECT: the invention ensures production of the solid dispersed abrasive compositions for clearing solid surfaces.
