Problems solved by technology

Traditional building curtain wall materials stone products are difficult to process, brittle and heavy; metal curtain walls have simple decorative effects, poor strength, and are easy to deform; precast concrete is too bulky and is not suitable for application in high-rise building large plate structures
However, due to the poor stability of glass curtain walls, serious light pollution frequently causes glass rain hazards in cities.
[0003] In this case, fiber-reinforced cement products have attracted the attention of experts at home and abroad due to their advantages of high strength, light weight, outstanding decorative effect, and high plasticity. In the industry, fiber-reinforced cement products are generally prepared by spraying or pouring. There are two aspects in this process. Big disadvantages: First, due to the three-dimensional anisotropic distribution of fibers, the mechanical reinforcement effect is not obvious, and the size of the product is greatly limited, and only small building components can be prepared
Second, the semi-manual production process makes the product unable to be standardized and scaled up, resulting in poor performance stability
On this basis, many manufacturers adopt the process of laying multi-layer fiber mesh cloth to compensate for the reinforcement of cement-based products. Through the two-dimensional directional distribution of fibers, the mechanical utilization efficiency of fibers can be improved to a certain extent, and at the same time, structures in different directions Uneven stress, easy to cause cracking and low flexural strength when preparing large plates
