Plastic building materials can not only replace a large amount of steel and wood, but also have superior performance that traditional building materials cannot match. It can significantly save energy, protect the environment, improve living environment and conditions, and enhance building functionality. With the continuous improvement of plastic building materials technology, its promotion and application will develop rapidly.
Currently, plastics play an important role in modern architecture. Due to its rich colors, strong decorative properties, no fear of moisture or insect damage, and easy installation, disassembly, renewal, and cleaning, it is widely used in the indoor decoration industry and deeply loved by people.
Plastic as a building material has many advantages, but there are also disadvantages. During production and use, attention should be paid to:
Lightweight, with high specific strength
Generally speaking, the density of plastic is 0.9-2.5g/cm3, with only 1/8-1/4 of steel, 1/2 of aluminum, and 1% of concrete. Therefore, using plastic instead of traditional materials in construction can not only reduce the weight of the building, but also bring convenience to the construction. For example, the installation of UP-VC drainage pipes is much more convenient than cast iron pipes.
In addition, the specific strength of plastics (calculated by unit mass) is very high. Some reinforced plastics have a specific strength similar to or even higher than steel (such as alloy steel). The unit mass tensile strength of plastic is 160 megapascals, and the unit mass tensile strength of glass fiber reinforced plastic is 170 megapascals.
