Shanghai Daoqin Plastics Co., Ltd.

         polyamide (PA) nylon (Nylon)

        英文名称Polyamide(简称PA), is separation 子主链 upper has heavy amine 基团—[NHCO]— thermoplastic property resin 总称.

        现 in already development formed large general purpose engineering plastics 之首.

         its causes is nylon comprehensive property can good, raw materials 源广, product types more 样, easy processing molding, easy modified, modified rear property can can to large improve/increase, make nylon application areas 变 也越 越广泛.

        基于 nylon a large amount of use, nylon waste material versus 应也越 越 more, nylon waste material recycled industry 也油然兴起. is, positive is nylon application areas 广泛, types type more, formed nylon recycled material 参差不齐, versus recycled material price 也偏差 very more.

        1, effect/influence recycled nylon value factors

         nylon recycled rear due to color, property can and pure degree and other more factors effect/influence, make recycled nylon pellets price 参差不齐, main/primary performance in below/following 几点方面:

         color suitable property narrow, 估价越 low. ratio 如同样 is PA6 waste filament, light ratio has light price low, has color ratio natural color price low, black spots more price low.

        ▶ property can

         property can 差 材 material, suitable scope/range narrow, price 肯定会 low. especially is composite/compounding testing property can low material, again modified has or more or less defect.

        ▶ stability property

         for modified enterprise 说, recycled material stability property is very important amount indicators, and other grade material material, modified 厂愿意出 more high procurement batch stability material.

        ▶ quality 风险

        诸如 environmental protection, surface processing property, flow property type indicators, effect/influence modified material quality, formed quality 风险, can for modified enterprise non important.

        ▶ dilute property

        如 aromatic nylon, carbon nylon, flame retardant nylon and other and other recycled nylon material, can can can used for injection molding, can obtain more high price, versus for relatively less.

        2, achieve recycled nylon value most large methods

        由 upper 面几点 can 看出, recycled nylon pellets price is is property different formed price 差异, enterprise in production in can full can according to this for pellets separation grade classification, will recycled nylon price achieve most large 化. lower to several 例子, large 家参考.

         due to recycled material raw materials non 常广泛, 也就造 formed recycled material formed 份 于 complex, if pelletizing, make pellets property can most 差化, 也就造 formed pellets sales price upper 不.

         in production in, can according to raw materials 源, classification, this need non 常专业 人 做 this parts 专业 事. 当然, if cost in can front lower, again color classification, improves recycled nylon pellets 本身价 value.

        ▶ for pellets color separation grade classification

         for color separation grade can most large degree improve/increase recycled nylon suitable property, especially is in recycled nylon used for color product 时, recycled nylon color deep shallow degree, rate, black spots and other factors very large degree recycled nylon suitable property.

         another, from color and other grade and rate upper can 直观 初步判定材 material mechanical properties and other grade, transparent 越净白 材 material can 反映出 recycled nylon in recycling process in to and bad less.

         market upper, large separation enterprise according to recycled nylon light transmittance different will recycled nylon separation is: has light nylon, light nylon and black nylon.

         can again through color device color sheet/plate Lab value, color standards 区间进行 color and separation grade.

         utilizing black spots 卡进行 testing, according to standards in black spots large small and amount separation grade.

         can use 嗅觉进行 odor 识别, has 异味 材 material can used for effect/influence 人们身体健康 product in.

         upper classification is 确定材 material in color suitable property, nylon as is engineering plastics 之首, its main/primary application scope is in for machine strong/high degree and resistant temperature property has relatively high requirements product upper, therefore mechanical properties testing can less, if recycled nylon 未经测定就盲目 use, very easy quality 事故并造 formed heavy rear 果.

         for will raw materials 进行均化拌 material rear, 抽取一定数 amount raw materials testing, main/primary testing force property can and moisture content testing. can according to testing 结果, for raw materials separation type.

         composite/compounding testing. raw materials in or material, for composite/compounding modified formulation has very large effect/influence, especially is high impact resistance nylon 时, and content for impact strong/high degree effect/influence non obvious. through Common glass fiber reinforced and toughened impact formulation, very easy 发现材 material in is has more material.

        针 for applications raw materials. and modified 厂家建立良 good 关系, necessary 互动, batch material most good increase 一组模拟 formulation testing, 以便确认该 batch raw materials in use in is 否会出现 other issues. large amount use formed more large 浪费, this 样既保护 客户利益也维护 自己 利益, combined as 关系也 more can good development.

         according to above methods for recycled nylon pellets separation type rear, can according to requirements 进行针 for property supply raw materials, this can:

        ★ 尽 large degree ensure material quality stability property;

        ★ 尽 can can ensure most products property can stability property;

        ★ versus improves recycled nylon pellets value, true positive will recycled nylon raw materials value achieve most large 化.
