Scagliola selection of common sense

Along with the development of modern architectural career forward for decoration materials, light weight, high strength, beautiful view, many varieties requirements. Man-made stone is facing appear in this situation. It is light weight, high strength, corrosion, pollution, construction is convenient, decorative pattern design can human control, is the ideal modern architecture decoration materials. Scagliola according to production and raw materials used in production craft, can generally be divided into four categories:

(1) cement type artificial marble this artificial marble is all sorts of cement as binder, sand for fine aggregate, broken big lidan, granite, industrial waste for the coarse aggregate, such as by ingredients, stir, molding, pressure steaming raise, polished, polishing and manufactured, commonly known as the terrazzo.

(2) polyester artificial marble this artificial marble is unsaturated polyester as bond, and quartz sand, Dali stone, calcite powder etc, mixing cast forming, in the influence of curing agent for use by stripping, drying, polishing processes and manufactured. Our production of artificial marble multi-purpose method. Unsaturated polyester gloss and color shallow, adjustable into different bright color, this kind of resin low viscosity, easy to forming, curing fast, but at room temperature curing.

(3) composite artificial marble this artificial marble is inorganic materials and organic polymer compound composition. Use inorganic materials will be binding forming, packing and given photo-cell and dipping in organic monomer, make its polymerization in certain conditions. Concerned, bottom of plate with lower and performance and stability of inorganic material, facing with polyester and Dali made of stone.

(4) sintered artificial marble the artificial marble is will feldspar, quartz, pyroxene ", calcite powder and hematite powder and mix, with a few kaolin etc, for with mud legal blank half dry pressure molding, used in kiln about 1,000 C into high sintering.

The above four artificial marble decorative, polyester most commonly used, its physical and chemical properties, decorative pattern design, best to a variety of purposes, reproducibility, but the price is relative taller; Cement type the cheapest, but corrosion resistance is poorer, prone to crackle, only suitable for the plank. Two other production process complex, rarely used.

Polyester scagliola (often referred to as artificial marble) is imitate marble surface texture and processed, the mechanism of similar marble, and decorative pattern design features can be determined by designers to control, reproducible; And artificial lidan light weight (better than the natural big lidan light about 25%), high strength, thickness thin, corrosion resistance, and have good pollution, processability can be made into arc, surface shape, construction is convenient. High quality faux marble physical and mechanical performance can be equal or better than natural marble. But in color and texture than natural marble beautiful natural and downy.

The influence of raw material for artificial marble, many for outdoor project artificial marble effect is not ideal. Main show is aging faster, color change is big, glossiness change is big, make use after period of time, adorn panel will seriously deformation, four horns upgrade becomes warped, some engineering may not expand bolt to secure its. Therefore, artificial marble is unfavorable for outdoor can be used for large outdoor cylinder, facade adornment, but when height exceeds 1.2 m when wire or stainless steel used a fasten.

Artificial marble can be used in indoor ground and metope adornment, also can produce all kinds of work, such as born clean basin that wash a face, bath crock, implement, etc. In addition, artificial marble also can be used in the manufacture of handicraft products, such as imitation stone carving, jade article, used for interior decoration.
