The hottest prefabricated building makes the coati

  • Detail

The prefabricated building makes the coating cold. Does the coating enterprise have a new turn?

statistics show that the global prefabricated building market in 2017 was $195billion, a sharp increase of 20% over last year. Different from the traditional manual construction method, prefabricated building is a new standardized and industrialized production mode of building. Its development can realize "building a house like building blocks", which has received great attention from all countries around the world

in recent years, the concept of building green environmental protection has been highly respected in China, and prefabricated buildings have gradually become a new trend in the construction industry. In 2017, the market scale of prefabricated buildings in China was about 68.5 billion yuan, accounting for 35.1%. With the further promotion of urbanization in China, the market scale still has higher room for growth

30% in ten years

as early as February 2016, "several opinions of the CPC Central Committee and the State Council on Further Strengthening the management of urban planning and construction" pointed out that prefabricated buildings should be vigorously promoted to reduce construction waste and dust pollution, shorten the construction period and improve the quality of the project. Increase policy support, and strive to use about 10 years to make prefabricated buildings account for 30% of new buildings

in 2017, many provinces and cities intensively issued guiding policies to vigorously develop prefabricated buildings and actively promote prefabricated buildings. At the time of 2018, prefabricated buildings have become the focus of local construction work

among them, Beijing stipulates that in 2018, the proportion of prefabricated buildings in the new construction area will reach 2, which allows us to accumulate a large number of customer resources of more than 0%. By 2020, the proportion of prefabricated buildings in the new construction area will reach more than 30%; Guangdong Province stipulates that by 2020, prefabricated buildings will account for 15% of new buildings; The goal of Jiangsu, Zhejiang, Hunan and other provinces and cities is to achieve the proportion of prefabricated buildings in the new building area by 2020. 1. Precautions for oil change of universal tensile testing machine in Jinan period: more than 30%

the action plan for prefabricated buildings in the 13th five year plan issued by the Ministry of housing and urban rural development clearly states that in 2020, prefabricated buildings across the country represent an important step in the field of high-speed automatic sorting and plastic re classification, and the proportion of buildings in new buildings will reach more than 15%, of which the key promotion areas will reach more than 20%. According to the policies and regulations of various provinces and cities, the proportion target of prefabricated buildings in 2020 is mostly about 30%. Zhangshoufeng, vice president and chief engineer of the prefabricated building Engineering Research Institute of the China Architectural Design Institute, revealed in an interview program that in the future, 80% - 90% of xiong'an new area will be prefabricated buildings. It can be seen that prefabricated buildings are the general trend in the future

reduced demand for architectural coatings

prefabricated buildings will carry out standardized processing and prefabrication of all accessories of the non load-bearing part of the building on the factory assembly line, and then carry out assembly of accessories on the construction site, transforming the original construction workers into mechanical operators, realizing dust-free operation, greatly saving manpower, time and energy consumption costs, and improving construction quality. Through mold, mechanized spraying, baking to produce; Roof truss, light steel keel, various metal hangers, connectors, floors and roof panels can also be prefabricated by the factory; Indoor materials such as gypsum board, flooring, ceiling, paint, wallpaper, etc. should be manufactured through the production line

with the development of prefabricated buildings, to a certain extent, it means that the demand for architectural coatings decreases. Will it bring crisis to the coating industry

in prefabricated buildings, compared with 50 square meters of house types, traditional decoration needs 11 tons, while prefabricated industrialized decoration only needs 4 tons. With the improvement of technology and the realization of "full assembly", the labor cost is greatly reduced, and the material cost is also greatly reduced

almost all the preliminary works of prefabricated buildings are carried out in the factory. On site, they are only assembled without slotting or pouring too much concrete. The main types of components are: exterior wall panels, interior wall panels, laminated panels, balconies, air conditioning panels, stairs, precast beams, precast columns, etc. At the same time, it seems that no wall coating has been found. Some people claim that with the advancement of prefabricated buildings, wall coatings will gradually disappear. At present, it is impossible to predict whether it will disappear. It is undeniable that the market share of coatings in the construction field will decline

new opportunities for waterproof and thermal insulation materials

commonly used waterproof materials in construction projects usually include asphalt based waterproof coiled materials, polymer waterproof coiled materials, and waterproof coatings, which are divided into asphalt based waterproof coatings, polymer waterproof coatings, and inorganic waterproof coatings. In addition, other waterproof materials are mainly grouting and plugging materials, waterproof agents, Waterstops, water stop adhesives, bentonite waterproof blankets, etc. According to the policy requirements, by 2020, prefabricated buildings will account for 15% of new buildings, including more than 20% in key areas. Many places have begun to implement the construction, and the scale is gradually expanding, while waterproof and thermal insulation materials are also spreading out

with the accelerated promotion of prefabricated buildings, waterproof, thermal insulation materials, wall materials, external wall tile finishes and other related industries have also ushered in new opportunities. Different from the requirements of traditional buildings for components, prefabricated buildings have new requirements for air tightness, thermal insulation effect and other aspects of doors and windows. In addition to the continuous demand for building paint products, the demand for building materials products such as high-quality building thermal insulation materials, thermal insulation decorative finished boards, waterproof materials will increase significantly

although the requirements of prefabricated buildings on parts and components are strengthening, high standards indirectly eliminate backward production capacity, so that parts and components enterprises can be more competitive in the market. At the same time, it brings new development opportunities for industries in development difficulties, and promotes the standardization of the real estate, building materials industry and home decoration market. It may also be a new breakthrough for the coating industry
