Method and apparatus for making composite solid surface article and composite solid surface article containing large particles

摘要

A method and apparatus for producing a composite solid surface article are disclosed. The method includes feeding a first composition toward a mixing point and feeding solid particles toward the mixing point. The method further includes mixing at the mixing point the first composition and the solid particles fed to the mixing point to form a second composition, and transferring the second composition away from the mixing point. The method further comprises polymerizing the polymerizable compound in the second compound so as to form a curable composition comprising the solid particles. The apparatus includes a solid particle feeder, a slurry feeder and a blender configured to blend and transfer a mixture of the solid surface forming slurry and solid particles away from the blending area. The composite solid surface article produced using the method and apparatus contain particles with a size greater than 5 mm.
