artificial stone can be roughly divided into resin, composite, cement, sintered artificial stone; artificial stone plate processing into a countertop is welcomed by the whole world because of the reasonable price; domestic artificial stone manufacturers generally refer to resin-type artificial stone, which can It is divided into artificial marble, artificial stone quartz stone, artificial stone granite and so on.
Artificial Stone is Classified By Material:
1. Resin Type Artificial Stone:
Resin type artificial stone is made of unsaturated polyester resin as cementing agent. It is combined with natural marble crushed stone, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and then added with catalyst, curing agent, pigment and other admixtures. It is processed by mixing, solidification, demoulding, and surface polishing. The product using unsaturated polyester has good gloss, rich color, strong processability and good decorative effect; the resin has low viscosity, is easy to form, and can be cured at normal temperature. The molding methods include vibration molding, compression molding, and extrusion molding. The artificial stone used in the interior decoration project is mainly resin type.
2, Composite Artificial Stone:
The binder used in the composite artificial stone has both an inorganic material and an organic polymer material. The production process is: firstly, cement, stone powder, etc. are used to make a cement mortar body, and then the body is immersed in an organic monomer to be polymerized under certain conditions. For the board, the bottom layer is made of inorganic material with stable performance and low cost, and the surface layer is made of polyester and marble powder. The inorganic cementing material can be made of fast hard cement, ordinary Portland cement, aluminate cement, fly ash cement, slag cement and plaster of Paris. The organic monomer may be styrene, methyl methacrylate, vinyl acetate, acrylonitrile, butadiene or the like, and these monomers may be used singly or in combination. The composite artificial stone product has a lower cost, but it is susceptible to spalling or cracking after being affected by the temperature difference.
3, Cement Type Artificial Stone:
Cement-type artificial stone is an artificial stone made of various cements as cementing materials, sand and natural crushed stone particles as coarse and fine aggregates, which are prepared, stirred, pressurized, steamed, polished and polished. In the preparation process, the color material is mixed and can be made into colored cement stone. The production of cement-type stone is convenient and inexpensive, but its decoration is poor. Terrazzo and all kinds of flower-step bricks belong to this category.
4, Sintered Artificial Stone:
The production method of the sintered artificial stone is similar to the ceramic process. The powder of feldspar, quartz, diabase, calcite and hematite powder, and a certain amount of aged soil are mixed together, and the general ratio is 60% of stone powder. 40% of the clay is prepared by a mixing method, formed by a semi-dry pressing method, and then fired at a high temperature of about 1000 ° C in a kiln. The sintered artificial stone has good decorative property and stable performance, but needs to be calcined at a high temperature, so the energy consumption is large and the cost is high.
Since the unsaturated polyester resin has a small viscosity and is easy to form; the gloss is good; the color is light, and it is easy to be formulated into various bright colors and patterns; the curing is fast, and the operation can be performed at normal temperature, so that among the above stones, the most used ones are currently used. Widely used, the resin type artificial stone produced by using unsaturated polyester resin as a cementing agent has stable physical and chemical properties and wide application range, and is also called polyester synthetic stone.
What is The Difference Between Quartz Stone, Natural Marble and Artificial Stone:
1: Natural Marble:
Based on natural stone
Advantages: Durable, the material is quartz stone, durable, the material color is quartz stone, artificial stone can not be produced
Disadvantages: The stone has high radiation and has a hole inside, which is easy to mold.
2: Artificial Stone.
Artificial stone refers to artificial stone solid surface material, artificial stone quartz stone, artificial stone granite and the like. The types of artificial stone are different and their composition is not the same. The ingredients are mainly resin, aluminum powder, pigment and curing agent.
Advantages: the price is cheaper;
Disadvantages: soft, easy to scratch; poor leakage resistance; easy to mold; susceptible to pollution; its fire resistance is not high.
3: Quartz Stone.
Artificial quartz stone is composed of more than 90% natural quartz and about 10% colorant, resin and other additives to adjust adhesion, curing and the like. It is a plate that has been subjected to vacuum production, high-frequency vibration molding, and temperature curing (the temperature is determined according to the type of curing agent).
Advantages: not easy to scratch, hard texture; has a certain sterilization effect; corrosion resistance, simple cleaning; high temperature resistance.
Disadvantages: the price is higher.
