        六 types plastics process process/workflow understanding 吗?接 lower let small belt/tape 您一同领略 this recycled plastics process process/workflow!

        一, recycled low density polyethylene (PE) (LDPE) process process/workflow

        LDPE, Scientific Names high pressure polyethylene (PE), it generally is plastics packaging film. 如: woven bag inner film, food packaging film, day use product packaging film, large film. this film large separation is natural color, has color, black, in recycling front most good color separation 开. can low pressure film,PP film in 一起, more can OPP and PVC film 放进. for LDPE recycling add again utilizing, is recycled LDPE process process/workflow. recycled LDPE process process/workflow main/primary has 四道工序.

        1. powder 碎工序. belt/tape water powder 碎冲洗效果则 more good. due to good high pressure film if maintain 足够 清洁, must add new material can heavy new film. therefore in powder process in need attention/notes 清洁, powder material to water rear most good again 次滚动, 目 进一步冲洗清洁点.

        2. drying 工序. generally is to dry machine water dry, has conditions 就进行晒 dry, this can electrical 费, improve/increase quality, need attention/notes anti material in dry in 二次污染.

        3. pelletizing 工序. specialized extrusion machine pellets, has types basic applications: again blow molding film and injection molding.

         in 60 to 80目 滤网 in 出 材 material can again blow molding; in 40 to 60目 滤网 in 出 材 material can meet/satisfy injection molding quality requirements. generally high pressure material again film, good Color Difference 一点吹黑 film and waste bag, plastics rear price more low.

        4. pellet cutting 工序, generally is cold water pellet cutting. this 道工序必 must attention/notes packaging separation 标号. types blow molding use, types injection molding use, 以免搞错. another, blow molding use packaging bag need outer bag add inner bag 以免二次污染.

        二, recycled polypropylene (PP) (PP) process process/workflow

        PP large separation day use product relatively more, plastics box/case, 脚盆, water 桶, 淘米篓, plastics 椅, 凳, woven bag and its it packaging weaving 布, belt/tape and other.

        1.首先 various material color separation 开, is separation use 户方便, price can high.

        2. belt/tape water powder 碎冲洗, to dry machine dry water, rear 进行晒 dry bag. use and machine and add color and additives.

        3. specialized plastics machine upper pelletizing, pelletizing temperature degree can high, easy 发脆, therefore need attention/notes temperature degree.

        4. water cold pellet cutting, need standards 3X4mm, again good material appearance good 看, standards.

        三, recycled polyethylene terephthalate (PET) (PET) process process/workflow

        PET, Scientific Names: polyethylene terephthalate (PET), it is types type thermoplastic property plastics

        PET usually is types crystallization type plastics,PET bottle due to quality light, easy 碎, can consumption low and other advantages, substitute/replace 一 传统 packaging materials, a large amount of application in food, material, product and other field/area. for PET recycling add again utilizing, is recycled PET process process/workflow.

        PET bottle sheet/slice recycling process, is will PET bottle and cover/cap, label and other separation 离, rear powder 碎, 清洗, drying.

         it specific process/workflow lower:

        1.首先 is 挑选工序: various PET bottle sheet/slice add 以挑选 and separation type. outer 面 商标, this large separation is OPP, has separation poly chlorine dilute shrinkage film, must 首先剥离.

        2. powder 粹工序, in powder process in belt/tape water 冲洗, remove various PET bottle sheet/slice in 污垢.

        3. this sheet/slice 放入蒸汽处理 plant/unit, add sheet/slice alkali, remove 掉油腻 and its it solid property 杂质.

        4. use water dry 净, dry water separation bag. rear to true 空烘箱进行烘 dry.

        5.喷 filament, type, use hot water 蒸汽移伸, again type.

        四, ABS plastics process process/workflow

        ABS plastics, large separation is electrical appliances product, multiple day use product and machine upper small parts.

        1.ABS relatively more is, electrical housing/shell, electrical machine housing/shell, table/sheet housing/shell, sheet/plate, decoration material, this material 挑开, especially electroplating, color and other need separation 开.

        2. chemical 处理, 退镀, 退漆, 但退镀退漆必 must heavy, chemical water has 一定配 ratio, need use anti use product and container, 否则会引起伤害 and other parts.

        3.清洗槽 清洗, rear dry, Color Matching or 放辅助材 material, is improve/increase quality.

        4. specialized extrusion machine pelletizing, 但一定 need upper 滤网, 但 滤网按 product requirements 而放.

        五, recycled polycarbonate (PC) (PC) process process/workflow

         polycarbonate (PC), non crystallization plastics, engineering plastics type. large is textile parts, automotive large 灯, 尾灯, toward 灯, made as mold, sheet/slice, electrical device 材, versus device and other.

        1.首先 acquisition PC挑选, has transparent transparent, 蓝, 红, 绿, must separation 开;也 has modified, textile parts large separation is modified;如碟 sheet/slice, 灯头都 is film.

        2.清洗各 color PC, and sheet/slice and other process, 也同ABS一样 principle as. rear dry, rear type, extrusion machine production.

        3.PC has comparison color, can production 瓷白; transparent still production transparent; its it color can add color agent and material additives.

        4. specialized extrusion machine pelletizing, 但PC本身 easy aging therefore can more material, pelletizing 一定慎 heavy, pellet cutting packaging.

        六, recycled polyvinyl chloride (PVC) (PVC) hard material process process/workflow

        PVC hard material large separation construction material, 塑钢窗门, electroplating hard sheet/plate 材, factory use plastics 阀门, lower water tube/pipe, decoration material.

        1.首先挑选工序, color separation 开. this material large upper separation is white, color, black types, need PP, PE mixed 进.

        2. to powder machine powder 碎, is belt/tape water powder 碎. 掉污染 belt/tape water 清洗, rear 进行晒 dry, anti 止二次污染.

        3. upper and machine 进行配 material, and. if is white material again add color agent, according to need additives and other.

        4. specialized PVC extrusion machine 进行刮粒, cooling bag 标号出厂.
