         will carbon acid and other machine material powder add to resin, to increase amount, improvement property can and increase function large function, is plastics filling modified. in use property can meet/satisfy lower, use powder more, reduce cost function large. from decrease/reduce 以石油 is raw materials combined formed resin use amount 看, for 社会 贡献也越 large. China development 进入“ new 常态”以 and growth 模式 改变, industry for filling modified plastics more more new requirements. 总体 看, light amount 化, function and 生态化 is industry future direction.

         light amount 化

         due to machine material powder density high polymer/macromolecule resin density (versus 差2-3倍), filling plastics material density add powder significantly increase large. mono weight material material, add has powder ratio pure resin small, therefore in parts 数, long degree, is its price 时, this elements decrease small formed loss 失往往 large use powder filler belt/tape 效益. in addition, increase heavy also belt/tape cost add large, strong/high degree large and other issues. 不, related research 发现, through 原辅材 material and process innovation, “ increase heavy issues ” can to 一定程 degree solution.

         tensile process

         polypropylene (PP) (PP)扁 filament will 近六倍 mono toward tensile rear, carbon acid powder pellets dispersion in PP large separation 子经拉抻 rear formed in, make weight material material, its filament long degree has obvious 变化, therefore high mono toward tensile products increase heavy issues obvious.

         blow molding plastics film in processing to di toward tensile, its tensile ratio different raw materials has different, generally is 2~3倍. therefore and add 同样数 amount powder injection molding plastics material versus ratio, blow molding film density small more.

         experiment/testing 结果也 table/sheet 明, make is injection molding, if can good injection pressure and holding pressure time, formulation and processing process equipment, its injection molding products material density can to 3~4% 变化.

         micro structure

         polyethylene (PE) (PE) separation crosslinked rear can formed 足够结实 泡孔壁, gas by 封闭住就 can formed micro plastics, from in crosslinked agent in lower, plastics material density decrease small.

         polyvinyl chloride (PVC) (PVC) and polystyrene (PS) (PS)都因 can formed strong/high degree 泡孔壁, therefore foaming process use crosslinked agent.

         micro foaming

         use crosslinked agent can to foaming PE plastics, its odor large crosslinked rear plastics 不利于 recycling utilizing. 武汉凌辉 polymer/macromolecule material has company in use crosslinked agent lower, make add has 30% heavy HDPE sheet/slice density ratio 同样配 ratio comparison sheet/slice density decline 10% above, already a large amount of used for HDPE sheet/slice product in, is light amount technology heavy large breakthrough.

         light filler

         micro silicon acid made formed material rear and carbon acid material 按同样 ratio/proportion add to HDPE resin in made as sheet/slice 材, its products density has obvious 差别, micro silicon acid micro material filling HDPE density in different add amount has 10% above decline degree, but also property can obvious 差别.

        晶 must carbon acid 钙

        赵学华 high according to in 橡胶材 material in use must carbon acid experience, will especially manufacturing must carbon acid add 以处理, again and plastics mixed combined, 结果发现, in effect/influence plastics material property can lower, can make its filling plastics density has decline. meanwhile nano degree micro also has 助于受 outer force 时发生 elastic property 形变, absorption impact can, has filling plastics maintain good impact resistant property can. 以Φ110mm PVC di 壁波纹 tube/pipe is 例, in its formulation in, use 经 特殊处理 晶 must carbon acid 钙代替 and other amount chlorine polyethylene (PE) (CPE) impact modifier, extrusion made pipe/tube property can table/sheet 1.

         experiment/testing table/sheet 明, use 经 特殊处理 晶 must carbon acid substitute/replace separation CPE impact modifier rear, pipe/tube property can still maintain good;CPE by substitute/replace pipe/tube tube/pipe material density relatively formulation pipe/tube tube/pipe material density has decline, decline 0.5~1%; in addition, is to different formulation pipe/tube heavy 一致, CPE by substitute/replace types pipe/tube in molding 时, add material machine speed add fast, this production weight pipe/tube time decrease/reduce, production efficiency to improve/increase.

         function and 生态化

         function is through add filler and versus additives, make polymer/macromolecule material tool has tool property can, flame retardant property, anti-static property, magnetic property, retardant property and other;生态化 is in filling plastics processing process in maintain environmental protection, energy saving, drop consumption. in filling modified plastics field/area, this types trend already 越 越 obvious.

         micro silicon acid 钙 缓释 and temperature function

         function property use film important function is and temperature. China currently production agent add to film in can to function, time short film lifespan, main/primary causes is use agent and PE separation versus property good, from film in 心迁移 to film surface 发挥流滴 function is must, 但迁移 fast, consumption fast, make agent function and film use lifespan can 同步.

         micro silicon acid 钙致密繁 more micro can 吸附流滴 agent, its toward film surface time, to function, long agent function time.

         related experiment/testing table/sheet 明, add has slip powder film slip powder in, in film outer retardant property good, hot amount outer methods 辐射穿 棚 film dispersion can force low, hot amount 以保留 in plastics large inner. micro silicon acid in formed is agent agent meanwhile, tool has and slip powder similar outer retardant function, formed is use film temperature agent, but also its temperature function ratio slip powder good.

         micro silicon acid high property environmental protection material

         utilizing micro silicon acid 钙致密, nano degree micro structure, can made formed 吸附异味 or has gas environmental protection type material. related research table/sheet 明, silicon acid material for aldehyde function obvious, 24 small 时 吸附 amount to 2.7%, carbon acid material and acid material tool has 吸附甲 aldehyde can force.

         in addition, use micro silicon acid material production SY320-720 type thick 2mm plastics sheet/plate 材时, 按HDPE: material =60:40 ratio/proportion extrusion calendering molding 时, use carbon acid material 时, extrusion has 烟, has 味, formed micro silicon acid 钙时, 模口处 烟雾 and 异味都消失, but also sheet/plate surface gloss degree good, color property can more excellent.

        此时, not only sheet/plate density from 1.28g/cm3 decline 至1.12%, but also force property can more good, to light amount 化, function 化, 生态化三 heavy modified 效果.

         powder surface active equipment high energy saving 效果

         carbon acid 钙, slip powder and other machine material powder surface has machine 化处理 can from hydrophilic water property is hydrophilic property. more year most use active equipment is high speed mixed combined machine, 但浆叶 high speed large negative 荷 旋转消 consumption electrical can relatively high, but also is 间歇操 as, in material and material 时, in in add additives 时, powder outer 扬, as ring separation poor.

         equipment manufacturing enterprise is for high speed mixed combined machine renovation, increase remove 尘设施, 改变母 material processing process, powder issues basic upper solution. enterprise made made formed 功连续处理 equipment solution high mixed machine 间歇操 as issues, powder 体处理 can consumption issues still has 根本改变, especially is active degree to ensure.
