Natural stone has excellent physical and mechanical properties such as high strength, hardness and durability. The surface is treated with beautiful colors and textures, and it has excellent decorative properties. The use of stone as a decoration in the indoor environment can give people a feeling of harmony, elegance, solemnity, nobleness, luxury, etc., and the factors determining the decorative performance of the stone are mainly the color, pattern, shape, size and texture of the stone.
The color of the stone is rich and varied, such as red rising sun, green jade green jade, white white jade white crystal, different colors such as Sichuan red, peach red, snow green, Mongolia black, St. James yellow, purple Luo Lan and so on, its natural texture contains the natural weather and the beauty of the time. The ancient Chinese used the unique color and texture of the stone to form a natural landscape painting. The shape, size and texture of the stone can be different according to its chemical composition, formation reasons and processing technology. Its size is large and small, the shape is concave and convex, the texture is rough, smooth and dull. Glossy, fired noodles, natural noodles, lychee noodles, longan noodles, etc., give people a rough, graceful, delicate, majestic, unrestrained, rigid psychological feeling.
In addition, both rough and polished stone have a simple, elegant natural beauty. In ancient China, some people commented on the use of the natural color of the stone and the natural texture displayed by the pattern. The "landscape painting" is "the blocks are all strange, all the wonderfully colored landscapes, the dangerous peaks are broken, the waterfalls follow the clouds, the snow cliffs Reflecting water, cascading far and near. The pen and pen are different, the cloud can live, the mountain is like a sound, not the five colors are splendid. The ancients' words have revealed the unique decorative properties of stone and people's love for nature.
As we all know, the color of stone is rich and varied. When we combine different colors of stone in a certain geometric pattern during production and processing, we can create many stone decorative crafts with better visual sense and more artistic appreciation. The role of decoration is to use a combination of different colors to change the atmosphere of the environment and create a beautiful and harmonious environment. The different patterns of various stone collages are elegant, solemn, not only have a very high artistic appreciation value, but also have a very high decorative value, giving people a very strong collision with the vision, which gives people a strong vision. effect. This kind of stone tiled products made of stone is very popular in hotels, hotels, shopping malls and comprehensive business buildings. The market prospect is very good. One of the most important reasons why this product is very popular is the visual sense and the visual effect.
Spherical lenses often used for aiming and focusing of monochromatic light source.Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. Because the spherical aberration of thePlano-Concave is negative, it can be used to balance the aberration of other lenses. This lens is widely use in optical display systems, projection optics systems, imaging and laser measureemnt systerms.
