 PP building board is an important tool for concrete structure construction. Experts pointed out that in cast-in-situ concrete structure engineering, board engineering generally accounts for 20%-30% of the cost of concrete structure engineering, 30%-40% of the workload of the project, and about 50% of the construction period. Formwork technology directly affects the quality, cost and benefit of Engineering construction, so it is an important content to promote the progress of construction technology in China. PP building template production line technology research and development success, reform the template construction process, make the template surface smoother, non-staining, energy-saving and environmental protection, light weight, easy to operate, wide applicability, easy to deal with heterosexual components, repeated use of many times, smooth clay surface, recyclable, no construction waste, etc., this is the wood template, even aluminium template, steel template can not be. Comparable. As a new type of green building formwork, building formwork fully conforms to the national environmental protection concept of "replacing wood with plastic". It is predicted that the emergence of PP building formwork will break the tripod situation of steel formwork, wood plywood formwork and bamboo plywood formwork that has gradually formed in the construction formwork industry of our country, and will create a brand-new green building formwork industry and open up China. New realm of building construction, to achieve the Chinese people's dream of green environmental protection, energy-saving and efficient building construction.
