With the strength of the country's power and the gradual improvement of the level of science and technology, the state's requirements for infrastructure have also continued to increase. The experience of many countries proves that it is an inevitable trend of economic development and social progress. The progress of the construction industry requires not only the quality and function of the building to be perfect, but also its appearance and harmless to human health. This requires the development of multifunctional and efficient new building materials and products. Only in this way can we adapt to the requirements of social progress.
The three traditional raw material templates can no longer meet the growing quality requirements of the current construction industry:
1. Wood formwork is the mainstream. Wood formwork consumes a lot of wood, and the residual value of scrap is low. It is necessary to cut down forests, violate the protection of forests advocated by national policies, and need to apply mold release agents during use.
2. In the past two years, Aluminium Formwork has appeared, and the cost is high. It is mainly leased, and a mold release agent is also used.
3. The combination of hollow plastic formwork and aluminum frame is now cheaper than aluminum formwork. No mold release agent is needed. It is easy to recycle. The operating mode is the same as aluminum formwork, and it is mainly leased.
Plastic Construction Formwork
Development prospects of the Plastic Construction Formwork:
Plastic building templates have been in use since the mid-1960s, and Japan first used ABS resin to make plastic templates. It has a history of more than 50 years. In recent years, plastic formwork has developed rapidly in Europe, the United States, Korea, Japan and other countries. Plastic formwork has gradually replaced the trend of bamboo, wood plywood and steel formwork, and gradually evolved to steel frame and aluminum frame combined plastic formwork.
In China, construction plastic formwork was only concerned and developed by enterprises and scientific research institutions in the early 1980s. In recent years, with the advancement of technology, Plastic Building Templates have been developed and developed rapidly in China, so plastic templates have broad development prospects.
At present, building plastic formwork has also been initially applied in construction engineering and bridge engineering and achieved good results. The plastic template is used in the construction of bridges, tunnels and other municipal projects and construction projects. At the same time, it can also solve the problem of concrete formwork in humid and chloride salt erosion environments such as cross-sea bridges and submarine tunnels, and lay the key technical support for civil engineering construction to enter the blue economy at sea.
Building plastic formwork is not only a technical innovation, but also a pillar of the construction industry. Therefore, the use of plastic formwork is one of the future development directions of formwork industry.
