Exterior wall decorative slate, soft porcelain, flexible stone decorative tiles, crack resistant and weather resistant building curtain wall materials

Description :

  Slate soft porcelain is a new type of lightweight building decoration material that mainly solves the problems of heavy weight, easy detachment, complex construction, and high resource consumption of traditional natural stone materials. It is composed of modified inorganic powder and polymer composite, presenting the texture and color of natural slate on the surface, and has a high degree of simulation. This product is suitable for various working conditions such as high-rise building exterior walls, old city renovation, indoor background walls, etc., especially for projects with strict restrictions on building loads or requiring rapid construction. Slate soft porcelain not only retains the natural beauty of stone, but also has flexibility, which can adapt to slight deformation of the base layer and effectively reduce the risk of hollowing and cracking. It is an ideal decorative choice for modern green buildings.

  The typical specifications and sizes of slate soft porcelain are flexible, with a common thickness of 2-3mm and a single piece weight of only about 3-5kg/㎡, far lower than traditional stone. The main body of the material shall be modified clay or stone powder sintered at high temperature, combined with anti-aging lotion, in accordance with industry standards such as JC/T 2418-2017 Flexible Stone for Decoration. Its surface has undergone special hydrophobic treatment, with a water absorption rate usually below 5%, and it has good stain resistance and self-cleaning function. In terms of physical properties, slate soft porcelain has excellent flexibility, with a bending diameter that can reach a certain standard without breaking, strong weather resistance, and can withstand UV irradiation, acid rain erosion, and freeze-thaw cycle testing. It has high color fastness and is not easy to fade after long-term outdoor use, ensuring the long-lasting beauty, safety, and stability of building facades.

  When selecting slate soft porcelain, it is necessary to clarify the applicable and unsuitable scenarios. It is very suitable for the construction of flat base surfaces such as concrete, cement mortar, insulation layers, as well as irregular structures such as curved walls, because of its flexible characteristics that can perfectly fit curved surfaces. For projects that pursue natural stone effects but have limited budgets or tight schedules, slate soft porcelain is an excellent alternative. However, if there are serious structural cracks or wet areas that have not been waterproofed at the grassroots level, it is necessary to first reinforce and waterproofed the grassroots before construction. Compared with real stone, slate soft porcelain is slightly inferior in texture and heaviness, but has obvious advantages in safety, construction efficiency, and overall cost; Compared with coatings, it has a stronger sense of three dimensionality and durability, and the purchaser should weigh and choose according to the specific needs of the project.

  The installation and maintenance of slate soft porcelain is relatively simple, usually using a special adhesive full bonding method for construction, without the need for dry hanging keel, greatly reducing the construction period. During construction, attention should be paid to the cleanliness and smoothness of the base layer, and the temperature is recommended to be between 5 ℃ and 35 ℃ to avoid working in rainy and snowy weather. In daily use, slate soft porcelain requires almost no special maintenance and can generally be kept clean by washing with rainwater. If stubborn stains are encountered, neutral cleaning agents can be used in conjunction with a soft cloth for wiping. Common faults such as local detachment are often caused by improper treatment of the base layer or uneven application of adhesive. Regular inspection of the sealing glue at the joint can effectively prevent water leakage problems. The service life of properly installed and maintained slate soft porcelain can reach several decades, during which it maintains color stability and reduces later maintenance costs.
