The present invention relates to transparent chips for artificial marble and artificial marble including the same. The transparent chips for artificial marble include (A) a halogenated epoxy acrylate resin and (B) metal fibers. The transparent chips are fabricated by adding metal fibers to a transparent resin. The transparent chips for artificial marble can implement both linear stripe patterns and three-dimensional effects inherent thereto, thereby providing an aesthetically pleasing appearance.

Transparent artificial chips and artificial marble comprising the same

Provided are a chip with a stereoscopic texture for a resin-based reinforced natural stone and a resin-based reinforced natural stone including the same. A chip with a stereoscopic texture can be obtained by coating a pigment on a surface of a crushed reinforced natural stone chip. In a resin-based reinforced natural stone to which the chip with a stereoscopic texture is added, a boundary surface between the chip and a matrix is formed, such that a texture of natural stone and a three-dimensional stereoscopic effect may be implemented, thereby making it possible to implement an aesthetically beautiful surface.

An artificial marble chip of the present invention comprises curable resin, metal fiber and/or inorganic fiber, and inorganic filler. The metal fiber and/or inorganic fiber preferably have an average length of about 1 to about 6 mm and an average particle diameter of about 10 to about 15 &#x3bc;m. An artificial marble according to the present invention is produced by using the artificial marble chip, curable resin matrix, and inorganic filler as main components. The curable resin is preferably selected from acrylic resin, unsaturated polyester resin, epoxy resin, or a copolymer thereof. The artificial marble according to the present invention is produced by the steps of: producing an artificial marble composition by mixing the artificial marble chip, the inorganic filler, and other additives into the curable resin matrix; and curing the composition at about 25 to about 180&#xb0; C. The invention can also include the step of defoaming the composition prior to curing.

Artificial marble having a transparent amorphous pattern includes a base or matrix material portion and a transparent pattern portion. The pattern portion has a specific gravity or about 1.60 or more and is formed by hardening or curing a resin composition comprising a binder selected from halogenated urethane acrylates, halogenated epoxy acrylates and combinations thereof and an acrylic polymerizable monomer.

Artificial marble with transparent and amorphous pattern

An artificial silica marble comprises a matrix and a line pattern portion. The line pattern portion comprises fine lines having a width of about 50 to about 500 &#x3bc;m and forms a web- or net-like pattern. The line pattern portion divides or partitions the artificial silica marble into a plurality of irregularly shaped pattern portions to form an amorphous pattern in the cross section of the artificial silica marble.

A demand response (DR) system includes a DR control unit to generate different DR levels having different power rates for each power unit, and transmit a current DR level, and a household appliance to receive the DR level from the DR control unit, and differentially control energy output of a product in response to the received DR level so as to reduce power consumption of the product. As a result, the DR system reduces power consumption when power rates are high so as to reduce electricity bills.

Demand response system

A demand response (DR) system, computer-readable medium and method are disclosed. The DR system controls a high-power-consumption load to be pre-operated or post-operated in a low-power-rate interval instead of a high-power-rate interval, and reduces an amount of power consumption required for a high-power-rate interval, resulting in reduction of power rates. In addition, limitation to household appliance operation is minimized, to greatly reduce inconvenience of a user.

Demand response method, computer-readable medium and system

The present invention provides marble chips produced by hardening or molding a resin composition including a binder and a reactive monomer, wherein the binder comprises a halogenated alkoxylated diacrylate oligomer. The marble chips of the present invention can be formed into a uniform pattern, so that an artificial marble made using the marble chips of the present invention may have an outer appearance and texture similar to that of engineered stone.

The present invention provides an inorganic artificial marble having excellent impact strength and weather resistance. The inorganic artificial marble can be a substitute for natural stone and used as an exterior finishing material.

Inorganic artificial marble and composition for inorganic artificial marble

The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.8, and the specific gravity of the transparent chips can be equal to or lower than the specific gravity of the matrix resin in promote uniform distribution of the transparent chips in the matrix resin.
