Faux stone siding is welcomed recently
Faux stone siding has fresh texture and natural color. As a wall decoration material, it has been loved and respected by people in recent years. However, with the increasing demand for natural stones in the housing decoration industry, manufacturers have been actively seeking alternative materials for natural stones. Pu (polyurethane) foaming material, as a substitute for stone, began to be applied to the production of faux stone siding.
What is Pu faux stone siding
Pu is the abbreviation of polyurethane, and its English name is polyurethane. PU foaming material is a new organic polymer material, once known as "the fifth largest plastic". It is widely used in many fields of the national economy because of its excellent performance. It has been used in the manufacture of various decorative materials since the 1990s. However, due to the load-bearing and strength problems, few polyurethane foamed products are based on Pu foamed materials.
PU foaming process
The manufacturing process of PU foaming faux stone siding is to add polyurethane foaming raw materials, catalysts, foam stabilizers, etc. into the mixture at one time. After high-speed mixing, it is foamed into foamed plastic, and then cured. The process does not need a prepolymer reaction device, and has the characteristics of simple process, less equipment investment and easy operation.
Advantages of PU foaming faux stone siding in wall decoration:
1. low price
We know that PU foaming materials are mainly used in Faux Stone decorative wall boards, especially in the realistic depiction of stone texture, which has the expressive power of root. In recent years, the cost of natural stone is quite high. On the one hand, the mining cost of natural stone is high. Secondly, the salary of carving workers is also rising. Therefore, PU foam rigid faux stone siding has a great price advantage in terms of raw materials and manufacturing costs.
2. superior performance
In terms of appearance, the texture, color and texture of Pu Faux Stone are very close to natural stones. The whole appearance can be integrated, and the painting effect and details are also very outstanding. In terms of functional strength, PU foaming material has high strength and low density, so it can not only cut and open holes like natural stone, but also carry out various complex carving processes on it, with superior processing performance.
3. high material utilization
The utilization rate of stone is generally about 30%. The utilization rate of PU foam rigid faux stone siding in furniture manufacturing can almost reach 90%, which also greatly reduces the production cost of wall decorative panels.
At present, PU foaming can be used in the manufacture of various simulated faux stones, such as carving, edge trim, decorative patterns, special-shaped parts, etc. For these special parts, PU foaming material has gradually shown its advantages
