A self-developed, listed as the first batch of clean production pilot demonstration and promotion projects in Shanghai, uses 100% expanded polystyrene (XPS) recycled materials to produce energy-saving and heat-insulating sheet technology, which is currently at home and abroad. This technology can not only eliminate "white pollution", but also turn waste into treasure, save oil resources, and make energy-saving insulation boards. The reporter learned from the national high-tech enterprise Shanghai Xinzhao Plastic Industry Co., Ltd. on January 31 that in 2009, Xinzhao Company's eight domestic subsidiaries have achieved annual sales of 600,000 cubic meters of XPS insulation board, and have made environmental protection at home and abroad. The market launch of XPS production line has been applied in more than 10 provinces and cities in China as well as Russia, Turkey, Egypt, Brazil, Romania, Kazakhstan, Azerbaijan and Saudi Arabia. It has provided "China created" for energy saving, emission reduction and low carbon economy. Technology and equipment.
According to Huang Zhaokang, chairman of Shanghai Xinzhao Plastics Industry Co., Ltd., XPS extruded insulation board production line made of 100% recycled polystyrene was independently developed by the company in 2001 and was included in the first batch of cleaner production in Shanghai in 2004. The pilot demonstration project has obtained 3 national patent authorizations and the technology has reached the international advanced level; it has successively achieved ISO 9001 quality system certification and CE industrial machinery product CE certification.
Over the years, China's plastics industry has continued to develop rapidly, especially in recent years when large-scale petrochemical projects are put into production and expansion. Polystyrene resins provide sufficient raw materials for the plastic foaming products industry, but they subsequently cause “white pollution†to the environment. The most common is that urban garbage is filled with a large number of polystyrene foam fillers and disposable foam polystyrene restaurant boxes that are used for shockproof packaging, and only 20 tons of “white waste†is produced in Shanghai every day. The government has to spend a lot of energy and financial resources to deal with pollution issues such as river courses and railway lines. At the same time, China's energy-saving emission reduction tasks are heavy, the vigorous development of the construction industry is an important area of ​​energy saving, energy-saving insulation board is facing increasing demand; XPS energy-saving insulation board unique micro-closed-cell honeycomb structure, with excellent pressure resistance, Anti-aging and water resistance, as well as good insulation and water barrier function. The imported equipment required for the production of XPS energy-saving heat preservation panels is sold at a price of more than RMB 10 million. Not only does it have a large investment, but also it requires high maintenance and operation of the equipment, resulting in high product costs and difficulties in promotion.
The scientific and technical personnel of Shanghai Xinzhao Plastics Co., Ltd., based on the successful trial production of the first XPS extruded polystyrene insulation board production line, developed a heat-insulating board production line that uses 100% XPS recycled materials. The price of this equipment is only one-tenth that of imported equipment, and it also achieves the clean production goal of “energy saving, consumption reduction, pollution reduction, and efficiency improvementâ€. The XPS board produced can be used as building insulation material. The company provides complete production lines and process technologies to domestic and foreign companies in a “turnkey†manner. It not only performs commissioning and product trial production at the equipment manufacturing site, but also performs machine installation, commissioning, and personnel training for customers at the site to make recycled materials. The polystyrene polystyrene XPS sheet industry continues to expand. The encouragement policy for recycling waste white plastics formulated by the Shanghai municipal government in recent years has promoted the recycling of Shanghai's “Natural Resources—Products—Recycling and Utilization†and the formation of recycling of polystyrene foam plastics built with market mechanisms. Industry chain. The successful development of this technology has greatly reduced the “white pollution†pressure on the environment in the society, turned waste into treasure, saved oil energy, and reduced the cost of energy-saving insulation boards.
Li Yunxiang, secretary-general of the Shanghai Green Industry Promotion Association, believes that the recycling of polystyrene scrap to produce XPS sheet is in line with the direction of circular economy and has broad prospects for development. He said that Xinzhao Company's production of XPS energy-saving insulation board using waste materials has promotion and demonstration effects and should be more widely promoted in China to ease the current energy shortage in China and improve environmental benefits. Taking 300 production lines for 300 days per year, it can digest about 450,000 tons of waste plastics, and at the same time it can promote the recycling of polystyrene foam plastic waste and increase employment opportunities. According to Liu Jingfen, secretary-general of the Shanghai Plastics Industry Association, the global market for insulating materials is huge. According to incomplete statistics, the annual sales volume of polystyrene, polyurethane and other thermal insulation materials exceeds 30 million cubic meters in the European market, and the United States is more than 20 million cubic meters. Starting late, but the market demand is growing rapidly, XPS insulation board will be used in a large number of energy-saving buildings. The production of XPS insulation board using recycled polystyrene as raw material not only has low raw material cost, but also finds a way to recycle and reuse the old polystyrene foam. It is recommended that local government departments should issue relevant policies to encourage recycling and use economic leverage to completely eliminate “white pollution†and promote the formation of an “industry chain of classified transportation, recycling and granulation—XPS production and energy-saving construction marketâ€.
