        随 recycling material application scope expand large, very more products in selection raw materials 时候会考虑 recycling material. however, plastics in processing, recycling rear property can large reduce, that 么, how to improve/increase recycling material property can, make its has new material property can is important, will is system 讲述.

different applications recycling material property can 特征

         different types type recycling material methods

         polyethylene (PE) （PE）

         recycling material property can: polyethylene (PE) recycled rear property can has decline, color 变黄, its in anti-aging property can decline most large. more extrusion rear, high density polyethylene (PE) viscosity decline, low density polyethylene (PE) viscosity upper rise.

        处理 methods: recycled utilizing can add mixed use amount generally is 8% below/following .

         polypropylene (PP) （PP）

         recycling material property can: one-time recycled 时, color 几乎不变, melt upper rise. above color add heavy, melt still upper rise. recycled rear, impact resistant and anti-aging property can decline most large, fracture strong/high degree and elongation has decline.

        处理 methods: recycled utilizing can add mixed use amount generally is 20% below/following.

         polyvinyl chloride (PVC) （PVC）

         recycling material property can: recycled rear color relatively obvious, one-time recycled extrusion rear belt/tape has shallow color, 三次则几乎变 is transparent color. ratio viscosity in 第二次时不变, above has decline toward.

        处理 methods: 无论 is hard also is soft polyvinyl chloride (PVC), recycled 时都应 add stabilizer. is make recycled products has gloss, recycled utilizing can add mixed use amount generally is 1%～3%.

         nylon （PA）

         recycling material property can: recycled rear elongation decline, elastic property has increase toward.

        处理 methods: recycled in color and property can decline issues, amount 以20％ below/following is 宜.

         polystyrene (PS) （PS）

         recycling material property can: recycled rear color 变黄, recycled polystyrene (PS) generally color rear use.

        处理 methods: recycled material property can decline degree and recycled formed positive ratio, fracture strong/high degree in amount small 于60%无 obvious 变化, viscosity in amount is 40% below/following obvious 变化.

         other plastics

         recycling material property can: ABS recycled rear color relatively significantly.

        处理 methods: 但 use amount 不 ultra- 20%～30%时, property can obvious 变化.
