What is the density of artificial marble?
Cement type artificial stone
Cement-type artificial stone is a variety of cement for the cementing material, sand, natural gravel particles for the coarse aggregate, by the preparation, mixing, pressure steaming, polished and polished made of artificial stone. Preparation process, mixed with pigment, can be made of colored cement stone. The production of cement-based stone is convenient and cheap, but its decoration is poor. Terrazzo and all kinds of bricks are of this type [1].
Resin-based artificial stone
Resin-based artificial stone is unsaturated polyester resin as a binder, and natural marble crushed stone, quartz sand, calcite, stone powder or other inorganic filler according to a certain proportion of cooperation, then add the catalyst, curing agent, pigments and other admixtures, Mixing and stirring, curing molding, stripping drying, surface polishing and other processes from processing. The use of unsaturated polyester products, good gloss, rich color, can be processed, decorative effect is good; this resin viscosity is low, easy to shape, at room temperature can be cured. Molding methods are vibration forming, compression molding and extrusion molding. The artificial stone used in the interior decoration works is mainly resin type.
Composite artificial stone
Composite artificial stone used in the binder, both inorganic materials, but also organic polymer materials. The production process is: first with cement, stone powder made of cement mortar body, and then immersed in the organic monomer in the monomer, so that polymerization under certain conditions. For the plate, the bottom with stable and inexpensive inorganic materials, the surface layer with polyester and marble powder production. Inorganic cementing materials can be used fast hard cement, ordinary portland cement, aluminate cement, fly ash cement, slag cement and plaster and so on. The organic monomers may be styrene, methacrylic acid methyl ester, vinyl acetate, acrylonitrile, butadiene, etc. These monomers may be used singly or in combination. Composite artificial stone products cost less, but it is affected by the temperature difference after the polyester film prone to peeling or cracking.
