The landscape boulders is a new type of handicraft stone carving that emerged as the times require. It has rich shapes and colors, and the finished landscape boulders is lifelike. It is very suitable for placing in public places. At the same time, the quality of landscape boulders is relatively light, and it is more convenient to carry. However, everyone also knows that there is no perfect thing in the world, so there will be some flaws in the landscape boulders. Then, what are the advantages and disadvantages of the landscape boulders, and then I will introduce them to you.
1. The advantages of landscape boulders
1. According to the needs, we can flexibly design landscape boulders products with various structures to meet the requirements of use and make the products have a good integrity. landscape boulders have strong corrosion resistance. This material is a good corrosion-resistant material, which has a certain resistance to the atmosphere and water. It has strong thermal properties and is a good insulating material. It is safe to use. Under certain high temperatures, it has certain functions of thermal protection and ablation resistance, which can play a very good effect. In addition, the landscape boulders has a simple process, can be formed at one time, and has outstanding economic effects, especially for products with complex shapes and small quantities that are not easy to form, its technological superiority is even more prominent.
2. FRP can be compared with advanced alloy steel. The tensile, bending and compressive strength of FRP can reach more than 400Mpa. It is a good corrosion-resistant material and has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and various oils and solvents. It has been applied to all aspects of chemical anticorrosion, and is replacing carbon steel, stainless steel, etc. Therefore, landscape boulders are more commonly used for decoration in parks and other places.
2. Disadvantages of landscape boulders
1. The elastic modulus of landscape boulders is twice as large as that of wood, but 10 times smaller than that of steel. Therefore, it often feels insufficient rigidity in the product structure and is easy to deform. It can be made into a thin shell structure, a sandwich structure, or it can be made up by high modulus fibers or ribs. Generally, it cannot be used for a long time at high temperature. The strength of general-purpose landscape boulders drops significantly above 50°C, and is generally only used below 100°C; the strength of general-purpose epoxy landscape boulders drops significantly above 60°C. However, high temperature resistant resin can be selected, so that the long-term working temperature is possible at 200~300°C.
2. Aging phenomenon is a common defect of plastics, and landscape boulders are no exception. Under the action of ultraviolet rays, wind, sand, rain and snow, chemical media, mechanical stress, etc., it is easy to cause performance degradation. The interlayer shear strength is borne by resin, so it is very Low. The interlayer adhesion can be improved by selecting a process, using a coupling agent, etc. The main thing is to avoid shearing between layers as much as possible during product design.
