One,
What kinds of marble are there?
Anyone who has seen marble knows that its color and pattern are dazzling and its variety is still very rich. According to the variety of marble, the naming principles are different, and some are named after the origin and color, such as Dandong Green and Tieling Red. Some are named after patterns and colors, such as Snow White and Ai Yeqing. Some are named after patterns, such as autumn scenery and The Waves. Some are traditional names, such as white marble and crystal jet. Therefore, due to different producing areas, the phenomenon of the same kind of synonyms or different rocks with the same name often occurs.
Marble can also be divided by color. Marble produced in China can be roughly divided into seven series according to the basic color of polished surface: white, yellow, green, gray, red, brown and black. Each series can be divided into several categories according to the color and pattern characteristics of its polished surface, such as: white marble, rosin yellow, Dandong green, Hangzhou gray and so on. The pattern and crystal size of marble are ever-changing, including landscape type, moire type and pattern type (line pattern, willow pattern, portrait, paleontology and so on. ) and snowflake type. Modern architecture is colorful and constantly changing. Therefore, decorative marble also requires many varieties and colors, which can be used in different parts of the building.
Marble is also classified according to its quality:
Grade A: high-quality marble, with the same processing quality and excellent quality, without impurities and pores.
Class b: the characteristics are close to the former type of marble, but the processing quality is slightly worse than the former; There are natural flaws; Requires a small amount of separation, gluing and filling.
Class C: There are some differences in processing quality; Flaws, pores and texture breaks are common. It is difficult to repair these differences, which can be achieved by one or more of these methods, such as separation, gluing, filling or reinforcement.
Grade D: The characteristics are similar to those of grade C marble, but there are many natural defects, and the processing quality is the biggest difference, so it is necessary to carry out surface treatment many times in the same way. This kind of marble has brought trouble to many colorful stones, which have good decorative value.
Second, what are their advantages and disadvantages?
As the most commonly used stone, marble has many advantages:
1, natural stone has natural grain, beautiful, hard, wear-resistant, scratch-resistant, and low price, which belongs to economical desktop materials.
2, good decorative performance, marble does not contain radiation, its color is gorgeous and rich, so it is widely used for indoor wall and floor decoration. Excellent machinability: sawing, cutting, polishing, drilling, carving, etc.
3. Marble has good wear resistance and is not easy to age, and its service life is generally about 50-80 years.
Marble is widely used in industry. Such as: used in raw materials, purifying agents, etc.
5. Marble has the characteristics of non-conductivity, impermeability and stable field position.
But marble is not all advantages, there are still some disadvantages:
1, high radioactivity, feeling cold;
2. Hard enough, but not elastic enough. Make the table top 1 meter or more. It is easy to be broken by heat or impact, difficult to repair, and difficult to process at the modeling place.
3, natural pores, easy to be polluted, easy to breed bacteria, easy to seep oil, easy to be dyed;
4. In the splicing operation, because the color of artificial rubber can't match the natural stone and its cross section is uneven, seamless splicing can't be realized.
Moreover, at present, natural stones are connected with domestic glue, which has a short life, is easy to get moldy and has formaldehyde content.
So much for the introduction of marble. In fact, every decoration material has its advantages and disadvantages. We should make rational use of it according to our actual needs and choose the one that suits us best, so that each decoration material can give full play to its advantages. Bian Xiao analyzed the varieties, advantages and disadvantages of marble in detail for everyone, hoping to make you plan more rationally when purchasing.
