Shanghai Daoqin Plastics Co., Ltd.

         in plastics products molding processing in, black masterbatch 几乎人人都 use, used for color, anti aging, conductive products and other and other. in use process in 常常会出现 various issues, 困扰我们. small will large 家共同关心 一 issues discussion, can to belt/tape 收获.

        1. black masterbatch formed?

        组 formed black masterbatch material has: A. carbon 黑;B. carbon 黑载体;C. carbon wetting agent;D. carbon dispersant;E. other processing additives.

        2. black masterbatch use carbon types type?

         according to classification, has more product types. main/primary separation is use and non use large type. in use carbon in main/primary is wear resistant carbon 黑, can has improve/increase 橡胶轮胎 wear resistance; in non use carbon in, true positive can as is black masterbatch carbon has types.

        以槽 method carbon in plastics in application most is 广泛, this main/primary due to its 源丰富, pure degree high, small. this its in, also separation is high color carbon 黑(粒径9-17mm), in color carbon 黑(粒径18-25mm) and low color carbon 黑(粒径26-37mm).

         due to carbon product types different, price very large. carbon pellets due to its tool has more active property, very less 以原生 pellets in, 几乎都以一定 scope/range 粒径 团 poly pellets in.

        3. carbon 黑载体 is how 回事?

        载体就 is carbon material 质. generally plastics products use what raw materials, 载体就 use what raw materials. this manufacturing black masterbatch and plastics raw materials versus property relatively good. 如: PS(polystyrene (PS)) plastics products, its use black masterbatch 载体就 is PS. for/regarding polyethylene (PE) plastics products, 载体就 is polyethylene (PE).

        但 is, generally selection LDPE(high pressure polyethylene (PE)), is LDPE承载 carbon can force most strong/high, processing properties good. other polyethylene (PE) HDPE and LLDPE can manufacturing low concentrated degree black masterbatch. for/regarding PP(polypropylene (PP)) plastics products, can use PP and LDPE is black masterbatch, can use HDPE and LLDPE and other plastics is black masterbatch. 当然也 has use recycling material 做载体 black masterbatch.

        4. is what carbon need wetting agent?

         carbon specific gravity 约2g/cm, due to carbon 黑粒径 very small, performance density very small, 显 蓬松, very light. need processing, must will carbon lubricating wet. wetting agent selection non key/critical. is reduce cost, a large amount of use or wax type product enterprise in less 数, this heavy effect/influence processing products strong/high degree.

        5. carbon material use which dispersant?

         main/primary separation is has machine dispersant and machine dispersant 两 type. high black material use has machine dispersant, main/primary used for use ring requirements relatively high plastics products, 如滴灌 product. low black masterbatch use machine dispersant, commonly used has carbon acid 钙.

         can from masterbatch packaging 判断, 25公斤 has semi bag is use machine dispersant;满 bag is use has machine dispersant black masterbatch. use machine dispersant can large large reduce black masterbatch cost, very is carbon acid tool has accelerated plastics products aging function.

        6. black masterbatch need processing additives 吗?

        当然 need. processing process need selection positive antioxidant, inner lubricant, outer lubricant, modifier and anti-static agent.

        7. black masterbatch has which processing methods?

         processing methods has types: mono screw method, di screw method and method .

         mono screw method : use material machine will material material mixed combined rear, mono screw extrusion machine strip/profile pelletizing, generally carbon concentrated degree in 18-20%, process rear, production ring conditions 差, by process, troubleshooting rigid small still use method processing.

         di screw method : use material machine will material material mixed combined rear, di screw extrusion machine strip/profile or water ring pelletizing, due to di screw machine mixing/compounding can force has 限, masterbatch generally carbon concentrated degree in 25-32%.

        密炼 method : use material machine will material material mixed combined rear, add 入密炼 machine combined rear, again material machine di screw extrusion machine, water ring or water lower pellet cutting, material generally carbon concentrated degree in 40-45%.

        8. processing methods for masterbatch property can has effect/influence 吗?

         this is 肯定. its in, method can improve/increase for carbon 黑 承载 can force, meanwhile carbon can more uniform 进入载体. 发挥密炼 machine machine combined advantages, 破碎团 poly pellets, make carbon pellets poly degree large large reduce, masterbatch in carbon 黑粒径 and its distribution uniform, is other types methods can substitute/replace.

        9. black masterbatch in which tool has performance?

         in plastics products color 方面, black masterbatch 需0.6%-0.8%, 就会奇黑无 ratio, again more add 也不会 more 黑. experiment/testing data 显示, in new 疆 区户 outer use products, need black masterbatch anti aging, need use excellent black masterbatch (而不 is material 做载体, lubricating wet, carbon acid dispersion and other and other black masterbatch).

         carbon in products in content to 2-2.5%, 即: 每100公斤 raw materials in, has 5-6份(weight)含 carbon 黑40% masterbatch, to function ultra- 任何 anti aging product, product lifespan can to 10 year above.

         this is is what product, water product, cable product is black. another, carbon for products strong/high degree increase, conductive property reinforcement and other 方面都 has 特殊贡献.

        10.实际 production in good has use this more black material?

        没错. production in generally use 2份 left right black masterbatch, again add anti aging additives, utilizing anti aging and carbon 黑 协同 function anti aging, reduce product cost. another, in outer use time long short, product lifespan requirements, 也决定 black masterbatch use amount reduce, front is carbon in product in must formed versus, has carbon 黑“ film ”保护 plastics.

        如 add black masterbatch less, carbon versus (即 small sheet/slice concentrated degree high separation) in products in 不连续, in versus and versus separation 界处, plastics separation most low, outer light 直接打击, accelerated oxygen aging reaction, carbon in products in 如同杂质, also 不如不 add. versus and versus separation small 于280mm时, can 躲避紫 outer light 打击, products is safety.

        11. how to from black masterbatch appearance its quality?

         quality good black masterbatch gloss and soft hard degree. 油 亮, 说明油放 太 more, gloss 黯淡说明载体 is material or carbon acid amount. quality good black masterbatch use 牙咬, in belt/tape 脆.

        太 soft has machine dispersant more, soft dispersion carbon concentrated degree low carbon acid relatively more, 脆说明 carbon content high, or is material.

        12. use black material rear products surface has small is how 回事?

         if is small 尖, products processing equipment dispersion material can force has 限, can will material in carbon poly pellets uniform, use concentrated degree relatively low black masterbatch; or masterbatch has more carbon acid and more 白油, by mono screw and di screw machine, in high pressure lower extrusion, formed small block, method dispersion. if is lower, is material in small separation material 质挥发造 formed, 说明白油 more.

        13.含 carbon acid black material can use?

         need comprehensive 看. 首先, black material in if carbon acid fine degree 1000目, content in 10%以 inner, for/regarding outer use requirements products, is selection, price low. product appearance gloss good, processing in carbon dispersion uniform, degree effect/influence, for product strong/high degree effect/influence relatively small.

         if carbon acid fine degree low 于1000目, can can gloss 黯淡, surface coarse 糙, products strong/high degree decline. if 1000目 carbon acid use amount ultra- 10%, products surface light 发灰白, degree 不够, products strong/high degree decline.

         its 次, in has anti aging requirements outer use products in, has carbon acid is good, product use lifespan selection is use.
