#dissolved polystyrene

Styrofoam (EPS) wide range of USES, often are one-time use at the coequal age, conjugate with its light powerfulness, volume and difficult to degradation such as broad market prospect. Curr<\p>

ently, the main EPS recycling method includes:<\p>

1) do a fade-out ousting method recycled polystyrene weave; This method, immeasurable energy consumption and recycl<\p>

ing of plastic inconvenience in situ desecration readying, and only a medium-sized truck shipment of 100 kg, is not the farm economy<\p>

2) Thermal breakup of recoup of styrene monomer, etc.; Ramified method technology, large appanage in equipment, the product performance is poorer, above cost and inconvenient to popularization and application;<\p>

3) Direct recycling strained granulating, add to the evergreen material recycling; Method the reuse ability is limited, and produces a large space anent scrunch in the harvest of crushing, unfavorable to the workers health<\p>

4) Mass-produced from solvent boost, glue adhesion agent. Both at home and abroad literature fortunate handy solve<\p>

nt recovery and adhesives, but mostly because of using solvents harmful or expensive to popularization and application. Using low-toxicity or nontoxic, cheap chloroform, made by thawing uninterruptedly of EPS plastic waste recycling after defoaming brimming switch, polystyrene lapsed can be obtained directly, at the same on credit toilet room easily taking place the prerequisite, is a sympathique of effective and honorable way, so as en route to hit it the serve of people. Literature sources of recovered solvents quod be divided into two kinds: one kind is the n<\p>

atural organic solvents, such as orange drug, grape the pill extract oil, ylang oil, etc.; Another kind is organic chemical solvents, such so benzene, toluene, ethyl benzene, deprive of life, crude acetate, etc. Including the use pertinent to natural solvent indolently is niggardly by the source of raw material, and generally smaller solubility. Synthetic inbred chloroform thawing efficiency is higher, at any rate are over and over specialistic to the raw material cost and toxicity<\p>

. This research intends to adopt in addition easily get primal solvent in behalf of recycling the solvent, through the credible distribution of way at the neck-and-neck race time, will the total loss of birthday suit materials and toxicity so achieve the supreme combination, get enough high dissolving efficiency and recovery, the balanced selection of recycling products, secure qualified products. This method is simple entrance deal with, does not produce secondary pollution, all simply convected heat process, save energy<\p>

The choice of solvents ideal be necessary persist: safe non-toxic pollution-free, reactants, the cost is low; To large amount anent dissolved polystyrene, dissolving speed; Facilitate delivery and recycling, and recycling utilization ratio is high. Based on the principle referring to this recollecting chose the ethylene chloride\toluene mixed solvent. The erosive did not be sensible of the edited version.<\p>
