waste 旧 plastics product types more 样, 形态各异, in in already 创造出 many recycled utilizing methods, lower brief introduction 一 实例供参考.

1, film recycling

film is plastics products in large 烊, types type more, use lifespan generally relatively short, is recycling recycled utilizing main/primary product types 之一, lower applications, brief introduction 实例.

（1） 农 use film, use film main/primary has film and film, film main/primary is PE film, has PE, PE/EVA, PVC film, in recycling recycled utilizing 时, will PE and PVC film separation 开, use film generally relatively 脏, 且常夹 belt/tape has 泥土, 沙石, 草根, iron 钉, iron filament and other, need remove iron 质杂质并清洗, recycling utilizing methods main/primary is pelletizing, if, tool separation 拣, conditions 时, 经清洗, drying rear waste film can use hot pressure methods production plastics products, 如盆, 桶, plastics method and other.

waste film recycled material applications lower:

1, PE recycled material , PE recycled material can use still production film, can use manufacturing packaging bag, waste bag, use recycled water tube/pipe, 栅栏, 树木支撑, 盆, 桶, waste 箱, 土工材 material and other.

2, PVC recycled material , PVC recycled material can use production heavy packaging bag, use water tube/pipe, shoe sole, and other packaging film, packaging film material 包括玻璃纸（赛珞玢）, PE, PVC, PP, EVA, PVDC, PA, PET以 and various composite/compounding film. mono 层 一 types material packaging film, in separation 拣, rear, can use film 一样直接 made formed plastics products or pelletizing rear made formed various products. composite/compounding film different plastics composite/compounding film and plastics and 纸, aluminum 箔, and other other material made formed film, recycling rear recycled need complex 一 如: more plastics composite/compounding film, more plastics composite/compounding film has PE/PP, PE/EVA/PE, PE/ bonding agent /PA/ bonding agent /PE, PP/PVDC and other, in recycled utilizing front, need will different material separation 离. separation can use solvent agent separation method.

（2） 纸塑 composite/compounding film, composite/compounding film in recycled utilizing front will separation 离, this is composite/compounding separation methods, separation equipment is belt/tape has electrical add hot 一镀铬空心 material 筒, material inner has belt/tape sheet/slice 空心圆筒, material and 空心圆筒以 versus direction 转动, rear mixed combined material add material 筒, in material in add hot mixed combined material upper plastics melt rear material lower material, 空心圆筒 in gas will waste gas belt/tape 走.

（3） aluminum composite/compounding film, aluminum composite/compounding film has BOPP/ aluminum, PE/ aluminum and other, used for various food packaging, use rear aluminum composite/compounding soft packaging bag is types mixed combined waste material, recycling utilizing relatively is difficult. methods outer main/primary is recycling hot amount. China has 焚烧取 aluminum and powder add filler made low coarse products methods, 效果不太理想. this introduction utilizing aluminum conductive property, manufacturing anti-static function material 例子, its process process lower: aluminum composite/compounding waste material —清洗— powder 碎— 筛—团粒— aluminum powder - additives — extrusion — semi formed product — extrusion — formed product. will aluminum composite/compounding waste material 经清洗, powder 碎 10 day 筛筛选, again 进行团粒, process can using/adopting plastics machine 械厂 团粒 machine. process conditions is water: 95 degree water 0. 8 rise, add material time: 3min; gas time 5min powder time 10min, 每次处理15千克. 经团粒 material material again use extrusion machine extrusion, formed semi formed product, will semi formed product again add 入20% aluminum powder, flame retardant, compatibilizer and other additives, again extrusion 选粒即 can products, used as conductive property material.

（4） PET film, in plastics industry, PET main/primary used as film and bottle, film can used as packaging, decoration, belt/tape or electrical container insulation, PET sheet/slice used as versus sheet/slice 基, PET也 a large amount of used for fiber, film and fiber use PET material property viscosity relatively bottle use PET纸. therefore recycling utilizing has 差异.

PET film and fiber production factory generate lower material can use and other polyester / ring oxygen resin powder coating material, generally this lower material versus for separation quality is 2万, melting point 260 degree above, is formed mono 一 线 type PET. will this lower material in 250至260 degree lower use more alcohol alcohol understanding, can versus for separation quality 约2000至5000 low melting point poly polyester. poly polyester in 200至220 degree add binary acid and ester agent polycondensation, acid value 约3. 05 mgKOH/g, soft 化点约 is 85至105 degree, 玻璃化 temperature degree small and other 于50 degree, material, material use made polyester / ring oxygen resin powder coating material.

PET lower material 723．6g binary acid 酐 0．98mol

binary alcohol 1．71mol catalytic agent 0．1%

PET industrial waste material can used as bonding agent. Japan large 阪市立 industrial research and 富士照 versus soft sheet/slice company use PET industrial waste material and reaction made formed bonding agent, used for metal bonding. PET industrial waste material use already acid or shrink ethylene glycol modified, can made hot melt adhesive, used for flexible material, 如布, leather, 纸, plastics, aluminum and other bonding. polyester / ring oxygen resin powder coating material property can

 5． polyurethane ester recycling

polyurethane ester types type 繁杂, its products has soft, hard foam plastics, thermoplastic property elastic property and industrial products and other, used for automotive, home appliances, chemical industry, day use and other field/area. recycling utilizing can types type separation 别进行.

（1） polyurethane ester soft foam plastics recycling, polyurethane ester soft foam plastics can using/adopting machine recycling methods. has ① use bonding agent 包覆, compression molding again utilizing ② low temperature recycling as filler

（2） reaction injection molding polyurethane ester recycling ① used as glass fiber reinforced RIM-PUR filler. ② and polypropylene (PP) blending. waste 旧RIM-PUR powder material and PP blending 凝土, can made flexibility property PP elastomer. methods has 1, active 化处理2, add compatibilizer 3, add machine filler. ③直接 compression molding recycling RIM-PUR recycling material powder abrasion fine rear powder material can compression molding made various products, 而不需添 add bonding agent. ④部 separation thermal degradation recycling, will RIM-PUR waste material in and machine in add hot degree and, make material in PU separation 子链部 separation fracture degradation, material hard is soft property 状态, again add 入异氰 acid ester make material in degradation PU separation crosslinked, made hard material, used for automotive tool and other requirements strong/high degree, hardness high and other.
 6． 酚 aldehyde plastics recycling

waste aldehyde plastics main/primary use use filler add aldehyde plastics in, add has waste aldehyde plastics raw materials material overall property can has decline, especially is notched impact strength, make add amount 仅5%, notched impact strength can reduce 35%, add waste aldehyde plastics pellets in large for property can has effect/influence, usually small material waste aldehyde plastics can improve/increase material property. add waste aldehyde plastics material notched impact strength has improve/increase, bending property can, electrical strong/high degree, water property and hot temperature degree basic 维持不变. waste aldehyde plastics recycling material for aldehyde plastics property can effect/influence material formed flexural strength /MPa tensile strength /MPa notched impact strength /(J/M2) notched impact strength /(J/M2) heat deflection temperature (HDT) degree /oC
