Polystyrene Recycling

Polystyrene plastic has many valuable properties, so in daily life, agriculture, transportation, military industry, aerospace industry, etc. have been widely used, 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 plastics because of their excellent thermal insulation properties and is used as building insulation material there is a huge potential for growth, and has broad market prospects. With China’s boomin...

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...

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...

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...

Instant noodles drums require soaking insulation properties, so instant noodles barrels once used as a packaging material polystyrene! But as people gradually realized, instant noodles barrels using polystyrene as the material has its insecurity, the packaging material in the bucket of instant noodles alternatives delete polystyrene choice! Although polystyrene foam tableware cheap, convenient, and usually instant noodles and water temperature cannot be achieved so that the release of hazardous substances  polystyrene temperature, it will be placed in the basic principles of consumer health first, so instant noodles barrels packaging materials continue upgrading, polystyrene has long been the stage of history! Diet of instant noodles place in our lives is somewhat awkward, on the one hand people cannot do without him, on the one hand people are afraid of instant noodles barrel polystyrene will release harmful substances, threat to human health. In this regard th...
