Polystyrene recycling review in developing country

Polystyrene plastic has many valuable properties in daily life, so it has been widely used in agriculture, transportation, military industry, aerospace industry, etc., particularly in the construction, packaging, electrical and electronic products, ships, vehicle and aircraft manufacturing and other fields has been a great favor. Such as televisions, refrigerators, washing machines, air conditioners, refrigeration systems and other household appliances, electronic instruments, precision instruments, glassware, ceramics, arts and crafts and other civilian light industrial products, mariculture rafts, frozen seafood, fresh vegetables , incubators, cold storage, refrigerated trucks, railway, municipal construction, all this is inseparable EPS plates and packaging products.

 Polystyrene plastic is used as building insulation material there is a huge potential for growth, and has broad market prospects because of their excellent thermal insulation properties. With China’s booming economy, the development of EPS industry in China has really entered a new area. Energy conservation is the strategic focus of the development of China’s energy industry, in 1986 the Ministry of Construction promulgated the “Energy conservation design standard”, subsequently this standard indicators further improved. Before implementation of building skill standards, China accumulated over the years built residential area of ​​nearly 80 million square meters.
Since 2000, energy-saving work of the heating zone differential thermal environment or energy consumption of the original building has begun in 2005, countries have begun to focus on energy-saving in town. Because polystyrene plastic sheet having low thermal conductivity, light weight, high strength, waterproof, impermeable, easy construction and other excellent performance, attractive in Rebuilding of Old Building. October 1, 2001, the Ministry of Construction issued a “hot summer and cold winter region residential building energy efficiency design standards,” the basic goal of polystyrene plastic are: polystyrene plastic in hot summer and cold winter area in China improve the quality of residential building heat environment, while improving energy efficiency, the use of polystyrene foam insulation and roofing sheet exterior insulation, building energy efficiency. Polystyrene recycling industry should be paid more attention especially in developing country.

XPS insulation board advantages

Image
1. Excellent thermal insulation Having high thermal resistance, low linear expansion lower than the characteristics of its closed cell structure rate reached more than 99%, forming a vacuum layer to prevent the flow of cooling air, ensuring lasting stability and insulation performance, relative to the urethane foam 80% the obturator rate, leading edge self-evident. Practice has proved 20mm thick XPS extruded insulation board, insulation effect is equivalent to 50mm thick polystyrene foam, 120mm thick cement perlite. Therefore, this material is the best choice for building insulation. 2. Excellent high compressive strength, due to the special structure of the XPS board, it has high compressive strength, impact resistance strong, depending on the size and thickness of XPS its compressive strength reaches 150 ~ 500Kpa above, can withstand all ground load system, widely used in geothermal projects, highways, airport runways, the square ground, large cold storage insu...

Polystyrene foam ceiling for Process Control

Image
Polystyrene foam ceiling process control points: ① The absorption of butane foaming agent as a foaming agent having a boiling point of -5 ℃. In order to ensure adequate absorption of butane PS, must be carried out in an autoclave at elevated temperature and pressure the reaction, the dispersion medium is soft soap powder as a dispersant, to promote uniform dispersion of butane. Polystyrene foam ceiling for Process Control Pressure within the autoclave control should be less than 10kg / cm2, at a temperature of 80-90 ℃, then PS soften, butane penetration into the PS. Then incubated 4-12h, PS in the butane content is generally up to a 7.5% to 5.5%. Cooled to below 40 ℃ discharge, obtained after washing the beads can be made of PS. Due to the distribution in the freshly prepared beads can be made of PS butane absorption is not very uniform, should be stored at low temperatures, a week or even a month, in order to ensure adequate dispersion of butane in the...

Airpop become new name of polystyrene in Europe

Image
Recently, according to the relevant source said: As the largest building insulation industry using polystyrene plastics (EPS), will be renamed “airpop- engineeredair” EPS had more than one name in Europe, such as Styropor, PSE, Piepschuim and Polyfoam. This change gives a generic name of such materials. British Plastics Federation EPS Group chairman David Emes explains:.. “Select Airpop is because the name can make people immediately think of such a material is made of air, in fact, more precisely, only 98% of the air needs a little PS can be extended to five times its original volume. this excellent material because of its lightweight, high impact and highly efficient thermal insulation in building and civil engineering industry has been widely used. at the same time, its products protects any need to protect the things – the child’s head, televisions, computers, fresh fish as well as in everyday life used in thousands of articles ” EPS Airpop® motion by th...
