Which is better, artificial marble or natural marble?
Marble is now divided into natural and artificial. It is well understood that nature is a Dali factory formed in nature, and artificial marble is artificially made through certain technical means. In contrast, natural marble is better, but there will be artificial marble, which also shows that the quantity of natural marble is small and the price will be higher.
1. Advantages of natural marble: dense texture but low hardness, easy to process, carve, smooth and polish. Marble is smooth and delicate after polishing, with natural and smooth texture and high decoration. Marble has low water absorption and high durability, and can be used for 40- 100 years. Natural marble slabs and profiles are important materials for indoor and furniture manufacturing.
2. Disadvantages of natural marble: The harm of natural marble mainly refers to the radioactivity in stone, which is a characteristic that many stone materials will have. There are two kinds of radioactivity in natural marble, one is that direct irradiation will damage the hematopoietic and nervous system of human body; The other is radioactive radon, which is radiated into the air and inhaled by the human body, which will increase the risk of lung cancer.
But don't panic, the harm of natural marble is very low, almost negligible. The radiation absorption of harmful substances emitted by natural marble is low, and the human body will hardly react.
The harm of marble is mainly due to the existence of artificial marble. Because the raw materials of artificial marble are derivatives of petroleum and contain harmful substances such as formaldehyde and benzene, the harm of artificial marble is even greater. Some unscrupulous manufacturers will add other harmful substances to the raw materials in order to maximize profits, which will further aggravate the harm of artificial marble.
3. Advantages of artificial marble: it has natural texture, and its senses and feelings are basically similar to those of natural stone; Small color difference, basically no color difference; Strong plasticity, customization and flexible use; The color is more uniform and looks better; Limited by natural stone resources, it is difficult to provide a large number of high-quality stone materials; Artificial stones generally do not crack and are easier to maintain.
4. Disadvantages of artificial marble: We all know that artificial marble is produced artificially, so there are many uncontrollable factors. Some "black-hearted" manufacturers use inferior materials in the manufacturing process in order to save costs. These materials generally contain formaldehyde, benzene and other harmful substances, and some also add organic solvents, resulting in the production of artificial marble into toxic marble, thus causing environmental pollution and affecting our health.
Artificial marble is made of natural marble or granite crushed stone as filler, cement, gypsum and unsaturated polyester resin as binder through stirring, molding, grinding and polishing. Therefore, artificial marble has many characteristics of natural marble. For example, artificial marble, because it can be adjusted manually, has many colors, good flexibility, inconspicuous joint treatment, strong sense of integrity, bright colors, ceramic luster, high appearance hardness, corrosion resistance, high temperature resistance and easy cleaning. But it also has a big disadvantage, which is very harmful to human body.
Natural marble is metamorphic rock formed by high temperature and high pressure in the earth's crust. It belongs to medium hard rock and is mainly composed of calcite, limestone, serpentine and dolomite. A few varieties, such as white marble and Ai Yeqing, which are relatively stable and durable, have pure quality and few impurities, and can be used outdoors. Other varieties are not suitable for outdoor use and are generally only used for indoor decorative surfaces. The main varieties are: cloud gray marble, colored marble and so on.
