1. The role of weather conditions in choosing the right mosaic There are mainly two types of climate in Iran: "cold and humid climate" In some seasons, these climates experience freezing water and sub-zero temperatures, so the mosaic must have the necessary resistance against very low temperatures. In areas with cold and humid climate, polymer mosaic will be a suitable material. Materials such as sand, cement, mineral stone, resin and fibers are used to make this type of mosaic. In a cold and humid climate, moisture penetrates into the internal texture of the mosaic, and this moisture causes cracking and erosion of the mosaic in the cold weather by freezing. To prevent the erosion of polymer mosaics, resin is used in their material. . Resin is a very resistant insulator to prevent water penetration into the texture of the mosaic.
"hot and dry climate" In this type of climate, the mosaic is more exposed to direct sunlight and high temperature. Mosaic is one of the building materials resistant to temperature and sun. In these areas, mostly mosaics are used, which have a smooth surface. In the cities located on the edge of the desert, warm provinces such as Khuzestan and provinces close to the Persian Gulf and the Oman Sea, we face the phenomenon of loose sand and dust in some seasons of the year. The smooth surface of these mosaics helps them to be easily cleaned.
2. Attention to quality in choosing the right mosaic Unfortunately, it is not possible to correctly judge the quality of the mosaic from its appearance. Therefore, to prepare quality mosaic, the best way is to refer to reliable manufacturers in this industry. There are mosaic factories in many cities of Iran, but cities like Isfahan, Tehran, Mashhad and Yazd are the main producers of this type of products in Iran, and the products produced in these cities are of higher quality and variety. There is a point of view about the quality of mosaic, and that is that the thicker the mosaic, the better its quality and durability. Although the thickness of the mosaic does not affect its quality and durability, the thickness is not the main reason for its quality. The quality of mosaic largely depends on the amount of cement used to make it. If a standard amount of cement is used, we will have a higher quality mosaic. If it is possible to check and view the mosaic before buying, pay attention to its corners and edges. Low-quality mosaics are most damaged in the edges during handling during production.
3. Reasonable price The appropriate price of building materials is one of the important factors for architects and reduces the final costs of the building. Manufacturers and consumers are always looking for the best quality at the best price. The price of mosaic depends on several factors: Type of machine: Mosaics that are made and produced with an automatic press machine are more expensive than mosaics that are produced with a manual press machine. Stone type: The type of material used to produce mosaic has a significant impact on its final price. For example, marble has a higher price than other stones. Another factor is the grade of the stone. The size of the diameter of the stones used in the mosaic varies between 0.5 and 8 mm, and after that, the plaque stone pieces, the bigger the stone score, the more expensive the price of the mosaic produced with it. 4. Transportation costs Since we saw a 2-3 times increase in transportation costs in 2019 and 2018 compared to 2018, the appropriate transportation cost is another important point in choosing the right mosaic for purchase. Mosaic is a heavy product. Usually, one square meter of mosaic weighs about 50 to 100 kg. And it is produced with a thickness of about 20 to 40 mm. Mosaics that are produced with a manual press machine have a thickness of about 20 to 30 mm, and mosaics that are produced with an automatic press machine have a thickness of about 30 to 40 mm. On the other hand, the amount of distance between the place of production and the place of execution of the mosaic should be taken into account so that it is affordable for the buyer in terms of transportation costs. Polymer mosaics and single-layer mosaics, because they are produced with a thickness of less than 20 mm, are suitable for transporting over long distances. Moreover, in the field of export to the countries of the Persian Gulf, we see a good reception of these mosaics, because these products have economic justification for export both in terms of volume and weight.
