Shanghai Daoqin Plastics Co., Ltd.

  due to thermoplastic property composite/compounding material made cost relatively low, but also tool has ratio strong/high degree high, corrosion resistant property strong/high, resistant creep property good, processing molding and low can consumption features, therefore in iron 路货车 upper tool has application outlook/prospects, is rail transit field/area tool development force new material product types 之一.  
iron 路货车 light amount 化 意义 
iron 路货车车辆 light amount is in structure quality has conditions lower, achieve structure most large 化, meet/satisfy structure safety can property.  
can property is 指承载 structure in use inner, structure 不发生 fatigue 失效. achieve light amount principle is in meet/satisfy function property and safety can property upper, achieve light amount design. main/primary 包括五 方面: ① combined separation structure quality;②充 separation 发挥材 material machine 械 property can;③消 remove or structure force in 效应;④ combined overall structure rigid degree;⑤ combined 理 材 material selection.  
货车车辆 light amount 化并不 is mono pure simple reduce 货车车辆 weight, upper high strength 钢, new type composite/compounding material and aluminum alloy table/sheet most 先进 货车车辆 technology.  
iron 路货车车辆 light amount is in ensure iron 路货车 safety strong/high degree and safety front lower, can can reduce iron 路货车 整备 quality, from high-speed rail 路货车 can can force, more more 经济效益.  
in currently full energy saving environmental protection large lower, iron 路货车 light amount already formed is full iron 路货车 manufacturing development trend. therefore, 钢质货车车辆车身 how to in ensure safety property front lower “瘦身” already is non 同凡响.  
thermoplastic property composite/compounding material brief introduction  
thermoplastic property composite/compounding material is thermoplastic type resin is 基体, fiber or its material is reinforcement composite/compounding material, tool has heat resistant property strong/high, ratio rigid degree high, ratio strong/high degree high and resistant oxidation property high and other advantages. currently already used for rail transit field/area thermoplastic property composite/compounding material has long fiber thermoplastic property composite/compounding material (LFT), fiber thermoplastic property composite/compounding material, carbon fiber composite/compounding material and other.  
thermoplastic property composite/compounding material in rail transit field/area application  
SQ6凹底 di 层运输 automotive specialized in composite/compounding material application  
SQ6凹底 di 层运输 automotive specialized is in 车北京二七车辆 has company design small automotive specialized 车, is currently inner automotive specialized most main/primary type, market has amount 约20000辆.  
SQ6车 type structure complex, separation is upper lower 两层, lower is structure, can relatively high SUV, MPV and small 货车. upper sheet/plate tool has rise drop function, 便于运输 different type. its in has separation parts already application thermoplastic property composite/compounding material, 包括: upper lower anti sheet/plate, add sheet/plate, and other.  
SQ6车 type upper sheet/plate tool has can upper lower adjustment function, in sheet/plate upper lower adjustment process in, heavy block upper lower 往复运动, upper lower anti sheet/plate function is anti heavy block and other material 体 接触. SQ6车 type use upper anti sheet/plate dimensions is: long × wide × thick =1000×960×7mm, lower anti sheet/plate dimensions is long × wide × thick =1100×960×7mm, 每车每 parts block. material is LFT thermoplastic property composite/compounding material. methods: anti sheet/plate and 车体连接位置 add sheet/plate, dimensions is 880×30×8mm, anti sheet/plate 两侧各7枚自攻 filament 螺钉安装.  
附 add sheet/plate is SQ6车 type has, is anti automotive 进入凹底部位造 formed automotive 托底, loss bad 车辆而 design. 闲置时悬挂于车体两侧, need 时安装 solid in 凹底部位 两侧, make 车辆进入凹底位置时 improves high degree, anti automotive loss 伤, 每车四 block.  
原 design material is SMC hot solid property composite/compounding material, in can recycling, environmental protection property issues. through for add sheet/plate structure optimization and combined material selection, currently already use LFT thermoplastic property composite/compounding material substitute/replace production, use 效果良 good.  
for optimization rear structure 进行模拟 type ratio analysis, 模拟装载 automotive 工况, 进行受 force, analysis.  
护栏 is tool has elastic property property product, 安装于SQ6车 type 两侧 侧墙 upper, anti automotive 车门打开 and 货车车体发生碰撞 loss bad 车漆.  
原护栏材质 is 橡胶, 橡胶 products 不 can recycling, and specific gravity large. product most long 22.8米, 橡胶护栏 weight is 46KG, 不利于工人 搬运 and 安装.  
is reduce weight and decrease light 工人 劳动 strong/high degree, SQ6车 type upper heavy new design use thermoplastic property elastomer 材 material. and through structure optimization design increase device, make product tool has function, in light conditions good lower automotive 时, automotive light 照射护栏会形 formed strip/profile light belt/tape, tool has and toward function.  
SQ7 automotive -普货两 use di in composite/compounding material application  
SQ7 automotive -普货两 use di is in 车北京二七车辆 has company design 运输普通货 material and small automotive specialized 车. SQ7车 type upper, lower sheet/plate is can sheet/plate, automotive can di 层存放车辆, 运输普通货 material will upper 层翻转 sheet/plate increase large can 运输空间.  
currently application thermoplastic property composite/compounding material product is: lower 层翻转 sheet/plate, upper sheet/plate strip/profile.  
SQ7附 add sheet/plate mono 车32 parts, product dimensions is long × wide × high 1440*1000*25mm. its function is in 运输普货工况 情况 lower, lower 层翻转 sheet/plate lower, make in and lower sheet/plate in 一 平面 upper, 便于叉车运输装卸普通货 material, 包括: 粮食, 化肥, 箱式货 material and other. requirements lower 层翻转 sheet/plate tool has relatively high resistant pressure, resistant strong/high degree. currently is LFT thermoplastic property composite/compounding material.  
SQ7附 add sheet/plate mono 车32 parts, product dimensions is long × wide × high 1440*1000*25mm, currently is LFT composite/compounding material.  
SQ7 upper 层翻转 sheet/plate strip/profile mono 车48 parts, product dimensions is long × wide × high 610*44*65mm, its function is in automotive conditions lower, 安装于 upper sheet/plate 边缘, and in strip/profile surface has light 标记, in 装载车辆时 tool has toward function. currently is LFT thermoplastic property composite/compounding material.
