A PVC hollow light wall

technical field

The invention belongs to the technical field of construction, in particular to a PVC hollow light wall.

Background technique

With the rapid improvement of the country's comprehensive national strength and the continuous increase of residents' income, the use function and quality of residential buildings have been further improved, and the transition from subsistence to well-off has been gradually realized. The technology of partition walls has become the "darling" of the flexible housing market , (Flexible housing means that the housing is divided into two parts: "support body" and "detachable body". The shell. The detachable body is composed of light partition walls, furniture, etc., which divide the shell into various functional spaces). The proposal of the supporting body theory has brought residential design and construction into a new stage. Designers and real estate developers only need to provide users with "house shells", and users can divide and decorate the space reasonably according to their own needs. The application of the partition wall has gradually become the decisive factor for the success of the decoration.

Modern buildings have developed towards high-rise buildings and large bays, and their functional requirements have been continuously improved. Traditional wall materials can no longer meet the requirements of architectural development. As a result, a variety of lightweight panels and lightweight composite panels that combine materials with different functions into various structural forms according to the design performance requirements and can fully exert the functions of various materials have emerged as the times require. This kind of light board and light composite board has the characteristics of light weight, excellent thermal insulation performance, good earthquake resistance, high fire protection level, convenient construction and installation, fast speed and increased building use area. Cities continue to emerge and gradually promote applications.

Although there are many types of flexible partitions available at present, the development levels of various regions are high and low, and the differences between cities are large. The understanding of flexible partition walls by engineering and technical personnel and users in various places is also different, and some even know little about them. This makes it difficult to develop flexible housing. Encourage real estate developers to build flexible houses, and together with design units and building material manufacturers, use various light wall panels to make sample rooms with different partitioned spaces to "guide" users' consumption. At the same time, strengthen the improvement of the quality, production technology, supporting materials and construction methods of existing lightweight partition wall materials, and continuously develop new lightweight partition wall materials with good performance to promote the development of flexible housing.

As a new type of building enclosure wall material, lightweight partition wall has the characteristics of increasing the use area, reducing the weight of the wall, improving the use function, reducing the comprehensive cost of the building, and improving the efficiency of building construction. In foreign countries, the utilization rate of lightweight partition wall materials is very high, but the utilization rate of lightweight partition walls in my country is insufficient at present. Therefore, there is a broad space for vigorously developing lightweight partition walls. However, the use of lightweight partition walls as partition walls has always plagued building designers and residents with the problem of sound insulation. At present, the sound insulation of the lightweight partition walls used in large quantities is difficult to meet the design requirements, which brings a lot of inconvenience to people's life and work, and disputes about wall sound insulation and environmental noise are also increasing. Therefore, Solving the sound insulation problem of lightweight walls is one of the key issues in the future application of lightweight walls.

At present, most of the lightweight partition walls used in residential buildings on the market are paper-faced gypsum boards, fiber-reinforced cement boards, ceramsite concrete, aerated concrete boards, steel wire grid sandwich composite panels, and colored steel sandwich composite panels. If these lightweight partition walls are used directly as interior partition panels in buildings, it is generally difficult to have a good sound insulation effect.

PVC is actually a vinyl polymer substance, and its material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, resistance to climate change and excellent geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids.
