Artificial stone is divided into four categories according to different production methods, but in fact there are two types of application: polyester artificial marble (referred to as artificial marble) and cement artificial marble (commonly known as terrazzo). Because artificial stone is light in weight, high in strength, corrosion-resistant, pollution-resistant, convenient in construction, diverse in pattern and low in price, it is an ideal decorative material and widely used. However, the quality of artificial stone is also different, and the quality of artificial stone often has the following characteristics: (1) The decorative pattern of the artificial pattern of artificial stone, especially the pattern of artificial marble is designed and produced in accordance with the pattern of natural marble. Imitation of realistic artificial marble has a decorative effect that can be chaotic, and the artificial marble of the quality has a beautiful surface pattern and a very poor decorative effect. For terrazzo, if the color of the cement variety and the color of the colored stone are not well matched, it will also affect the decorative appearance of the surface. (2) Appearance quality does not meet the requirements For artificial marble and terrazzo, the national standards also specify the corresponding appearance requirements and divide their quality levels. The appearance of qualified artificial stone should meet these requirements, while the quality of artificial stone, its appearance defects are beyond the standard range, and will certainly affect the decorative effect of the finish. Therefore, the appearance quality is an important factor in judging the quality of artificial stone. (3) Specifications do not meet the requirements For artificial marble and terrazzo made of sheet metal, there is also a requirement for surface flatness and uniformity of seams when laying. Therefore, the national standards also stipulate the dimensional deviation and flatness requirements they should meet to ensure that the entire decorative surface is flat and neat. If the specification size is not strictly controlled during the production process, it will produce a quality artificial marble plate, that is, a plate whose specifications and sizes do not meet the specified requirements. (4) Physical and chemical performance indicators are not qualified Also used as artificial stone for decoration, the selection of materials is still mainly based on the decorative properties of the surface. However, when evaluating the quality of the quality, in addition to considering the decorative properties, it should also consider its physical and chemical properties (such as compressive strength, flexural strength, hardness, stain resistance, corrosion resistance, durability, etc.), these properties are guaranteed The necessary conditions for performance to last. For example, polyester artificial marble, because its main bonding material is organic polymer material, will deteriorate in the actual use, especially under the long-term effects of sunlight, heat and air. For terrazzo with cement as binder, if it is not well maintained during production, it will have more pores on the surface of the board. If it is used, it will be contaminated with various pollutants such as oil, lipstick, vinegar, soy sauce, ink and red syrup. Etc., it will be absorbed and contaminate the surface, affecting the appearance.
