         plastics hot understanding material in has machine waste material made active property in function understanding 立平, rigid, 杨学民(China 科学院 process engineering research, 北京100080)明: in material strip/profile made process in, plastics hot understanding material tool has lubricated, adhesion function, can has decrease/reduce adhesion agent use amount; in material strip/profile stage/phase, due to plastics hot understanding material hot understanding, 析出, make material strip/profile tool has 发达 孔隙(闭 combined) structure, most make in rear active process in add fast active reaction speed degree, improve/increase active property 炭 吸附 property can; plastics hot understanding material in active property structure formed and development process in, tool has adjustment function.

         waste 直接焚烧 is achieve waste can 源化, decrease amount has 效手段, is world using/adopting. however waste 直接焚烧会 generate large issues, its is in waste process in generate 二恶英 ultra- 标排放, heavy ring 境; its is due to waste in separation formed property very large, therefore waste 直接焚烧会 for 焚烧炉 design formed difficult, waste efficiency reduce. for 二恶英 generate ring 境污染, currently using/adopting active property 炭吸附二恶英 methods add solution 112, solution issues has 效途径则 is using/adopting year research 出 结论一 waste can new 思路13-51. new 思路认 is, although waste in separation formed property very large, utilizing waste in separation hot understanding gas formed tool has very large versus property, make waste hot understanding again 焚烧则会 large large improve/increase waste utilizing rate, ratio 直接燃烧 more is has 利.

         in waste formed in, type, 纸张, plastics is types type solid has machine waste material, it not only tool has low 灰, high carbon amount features, and other waste separation 如家庭厨余16 versus ratio, more 适宜于 as is made active property raw materials, but also types waste material hot understanding material relatively 之未进行 hot understanding waste material more easy 破碎, make hot understanding material is raw materials made 备粒状 active property production process more easy achieve. therefore types type has machine waste material hot understanding material is raw materials, made 备适宜于脱 remove 二恶英 active property 炭, not only can remove waste for ring formed 污染, to waste waste 目, but also also can expand large active property production raw materials 源17, make waste can comprehensive utilizing new more 趋完善.

        基于以 solid has machine waste material hot understanding material is raw materials made active property research 尚未见报道, 我 开展 this 方面.

        由 can 见, plastics hot understanding material in temperature degree 440C left right speed hot understanding 而析出 volatile content, temperature degree to 500C left right 时, plastics hot understanding material full hot analysis 出;木炭 and mixed combined material in 0C~500C scope/range inner hot understanding relatively slow, in 500C above 时, hot understanding speed degree versus for relatively fast.

         table/sheet 明, types different plastics hot understanding material content mixed combined material, increase make active obvious reduce 而膣: content high! active process in material strip/profile 孔隙就越丰富 this mixed combined material, hot understanding heavy rate fast quality separation is 20 % hot understanding heavy rate, temperature degree 进一步 rise 至440°C~5⑴°C between 时, quality separation is 30% mixed combined material hot understanding heavy rate obvious fast quality separation is 20% hot understanding heavy rate, meanwhile types mixed combined material in temperature degree 区间发生激烈 hot separation understanding understanding in 500C above types plastics hot understanding material content mixed combined material hot understanding is also 趋于一致, hot understanding speed degree obvious 变缓, fast 于木炭 and mixed combined material hot understanding speed degree, can 推断此时 still has a small amount of future and separation understanding plastics hot understanding material in 继续进行 separation understanding;进一步 will plastics hot understanding material, and mixed combined material separation hot understanding data add 权平均计算, 发现两 types different plastics hot understanding material content mixed combined material hot understanding add 权平均 value and versus 应 实际 hot understanding heavy rate basic combined.

        由 and can 知, in same active conditions lower, plastics hot understanding material 〕 碘吸附 value significantly increase. this table/sheet increase plastics hot understanding material content, add fast active reaction speed degree, has active property 炭吸附 can force improve/increase. for combined 炭化, No.4则 is plastics hot understanding material quality separation is 20% 炭化 material strip/profile in relatively low rate 时 孔 structure 测定结果.

        由 table/sheet 4 in No.~No.3 can 知, waste material hot understanding material in plastics hot understanding material content main/primary for active property in 孔 形 formed, development generate effect/influence. plastics hot understanding material content increase 时, active property ratio surface 积, 总孔容, in 孔孔容均呈现出先 increase rear decrease/reduce 变化规律, micro 孔孔容则始终 in decrease/reduce, and in 孔孔容 versus ratio need small more.

         table/sheet 4 plastics hot understanding material content for active property structure effect/influence active property 炭 三 types waste material hot understanding material raw materials add 璐￡程代云. made active development new type material, bookmark10 table/sheet 4 in No.2 and No.4 测定结果, active property structure in active process in 变化情况. 当烧失 rate relatively low 时(如No.4 示 36.9 %) made active property tool has versus high in content, this table/sheet material strip/profile 炭化时 plastics hot understanding material rear lower in active main/primary formed in 孔;随 active 化 进行(如No. 示 烧失 rate to 68 %) in 孔孔容 and micro 孔孔容都 in increase, in 孔孔容 increase relatively micro 孔孔容 increase degree large, 说明伴随 active 化 进行, has versus micro formed in 孔, versus 当一部 separation relatively thin micro by active 化烧穿而 combined is in 孔, and meanwhile also has new micro generate. therefore combined plastics hot understanding material in material strip/profile 炭化, active process in function, plastics hot understanding material for active property structure effect/influence can understanding lower: plastics hot understanding material content high, 孔隙越丰富, 孔壁越 thin, meanwhile active speed degree fast, active speed degree add fast not only has make relatively thin micro combined formed is in 孔, but also in active process in also has generate new 孔隙, active property in 孔孔容随 plastics hot understanding material content increase increase. micro 孔孔容则始终 in decrease/reduce, decrease small degree relatively small;当 plastics hot understanding material content high 时, 则导致一部 separation in formed large 孔, therefore in 孔孔容 also decrease/reduce.

        综 upper analysis, through waste material hot understanding material in plastics hot understanding material content, can for active property 炭 孔 structure 进行一定程 degree adjustment, main/primary is for active property in 孔进行 adjustment.

        4结论°Q between speed hot understanding, full 部析出 hot understanding is features, make plastics hot understanding material not only is made is due to plastics hot understanding material in material strip/profile 炭化时 full hot analysis 出, add fast active reaction speed degree, for active property in structure formed and development tool has adjustment function, improve/increase active property 炭 吸附 property can; in addition plastics hot understanding material tool has adhesion property, can reduce material strip/profile molding pressure, decrease/reduce use amount.
