FIELD: construction.
SUBSTANCE: method and mixer are described for manufacture of manmade marble. Manmade marble, according to the first version, is produced by supply of the first composition, containing acrylic liquid resin, including one or more acryl monomers, inorganic filler and initiator of polymerisation, into the mixer. Mixer has shaft and one ore more blades or augers attached to shaft. Mixer does not have blades or augers on shaft in the area near inlet hole for supply of large particles. Large particles are supplied, which represent pieces of natural or manmade marble, into the mixer. The first composition and hard particles sent to the mixer are mixed. The second composition is produced. The second composition is moved to discharging hole of the mixer designed for unloading. Acrylic monomers contained in the second composition are polymerised to produce hardened composition, containing hard particles, and hardened composition is hardened to produce manmade marble. According to the second version, manmade marble is produced by movement of large particles, which represent pieces of manmade or natural marble or stone, and having size in the range from approximately 7 to approximately 100 mm, along channel. Then composition, containing acrylic liquid resin, including one or more acryl monomers, inorganic filler and initiator of polymerisation, is added to moved hard particles. Acrylic liquid resin is mixed with hard particles. Acrylic liquid resin is condensed in process of mixing. Fluid hard composition is produced, which contains hard particles distributed practically evenly. Fluid hard composition is hardened in mould to produce manmade marble. Mixer used to prepare composition for production of manmade marble includes inlet hole for supply of hard particles, inlet hole for supply of resin mixture, discharging hole for unloading of composition, containing hard particles and mixture of resins. Comprises shaft and one or more blades or augers attached to shaft with a certain pitch from each other for mixing and moving of composition towards unloading hole. Mixer does not have blades or augers in the area near inlet hole for supply of hard particles. Mixer is inclined towards discharging hole, and angle of inclination versus earth makes from approximately 5° to approximately 70°. Manmade marble produced with application of these methods and a mixer is also described.
EFFECT: manmade marble, due to even distribution of large particles, has new ornament.
