Polystyrene Recycling

Mentioned polystyrene , people may not be familiar with it. But when it comes to disposable lunch boxes, plastic bags, packing boxes with white plastic, I am sure you have seen and contacted, they are made ​​of polystyrene . In daily life, the polystyrene has become an indispensable good helper. Polystyrene (ps) is a colorless, transparent thermoplastic, has wide application in everyday life, is an indispensable material in modern industry. Most common is the expanded polystyrene (commonly known as Styrofoam, EPS). EPS is a lightweight polymer materials, with sound absorbing, sound insulation, heat insulation effect, hollow floor recently used in construction (new construction method) is EPS. Adding polystyrene blowing agent and then heating the blowing agent will soften and produce gas, foam polystyrene into a rigid closed cell structure. This uniform closed cavity structure makes EPS has a small water absorption, ex...

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...
