         color agent is plastics can less “ additives ”, sheet/plate small, 却赋予 this world color color, this world 以美, color is 展现美 most 直接 形式. tube/pipe is automotive home appliances day use product and other and other, 都离不开 color agent, positive is this additives, improves product inner in value and property. as is, raw materials production not only is is 欣赏美, also need how to stability can use 美. therefore, 今天我们就 讲一讲, plastics color how to selection color agent!

        1 PVC use color agent

        PVC is type important general purpose thermoplastic type material, applications 广泛, commonly used low and high 档特殊 property can requirements field/area construction material, automotive, and other, due to its processing molding temperature degree relatively low, can selection multiple type type has machine material color, still based on processing conditions, color product most applications and other for color agent 进行特定 selection, need 避免PVC color generate phenomenon.

        PVC color 时 喷霜 phenomenon can is is as is color agent has machine material in processing temperature degree lower separation solvent understanding and in room temperature lower generate material again crystallization function 而引起, phenomenon in other polyolefin plastics in 也同样存 in, especially for soft 质PVC材 material, add increase agent increase color agent in its in solvent understanding degree, make more easy generate phenomenon, but also processing temperature degree improve/increase, phenomenon add heavy; again 者, due to material and PVC between versus property 不够理想, especially in has certain additives 时, this 样会导致颜 material saturated and generate surface phenomenon, therefore for/regarding PVC color can different requirements selection different has machine material product types:

        ① general purpose color agent, tool has good property, resistant property generally (黄, and color) product types has: C.I.颜 material 黄61, C.I.颜 material 黄168, C.I.颜 material 橙13, C.I.颜 material 橙34, C.I.颜 material 红48:1, C.I.颜 material 红48:2, C.I.颜 material 红48:3, C.I.颜 material 红57:1, C.I.颜 material 红57:2.

        ② property can excellent color agent (黄, and color): product types has C.I.颜 material 黄139, C.I.颜 material 黄183, C.I.颜 material 黄191, C.I.颜 material 橙43, Graphtol Fast Orange 5GL, C.I.颜 material 红151, C.I.颜 material 红214, C.I.颜 material 红242.

        ③ suitable for outer color products color agent product types has: C.I.颜 material 黄24, C.I.颜 material 黄110, C.I.颜 material 棕23, C.I.颜 material 棕25, C.I.颜 material 红122, C.I.颜 material 蓝15, C.I.颜 material 蓝60, C.I.颜 material 绿7, C.I.颜 material 紫23.

        2 PA use color agent

         used for PA color agent can using/adopting has machine material, can selection solvent polymer material. used for PA color has machine material can separation formed 两 档次:

        ① application property can generally has machine material product types has: C.I.颜 material 黄148, C.I.颜 material 黄150, C.I.颜 material 黄187, C.I.颜 material 红149, C.I.颜 material 红177, C.I.颜 material 紫23.

        ② property can excellent has machine material product types has: C.I.颜 material 黄192, C.I.颜 material 橙68, C.I.颜 material 蓝15:3, C.I.颜 material 绿7. its in C.I.颜 material 黄192 is metal 鲜艳红 light color ring material, in low concentrated degree still tool has high resistant heat stabilized property (300℃) and excellent resistant gas degree, and can and titanium powder, zinc and other machine material use;C.I.颜 material 橙68 is has 苯并咪唑 ketone 基团 鲜艳红 light color combined material, tool has excellent lightfast and resistant thermal properties.

        3 polyester material use color agent

         polyester material (包括PET and PBT)既 can use material color, 如C.I.颜 material 黄138, C.I.颜 material 黄147, C.I.颜 material 红214, C.I.颜 material 红242 and other, more more combined is use can solvent polymer solvent agent material color, 如Estofil S(Clar), Polysynthren(Hö), Filester(Ciba) and other.

        4 ABS use color agent

        ABS color more using/adopting can solvent polymer solvent agent material, not only tool has good transparent degree, also has relatively good light degree, if and machine material use, can obtain transparent color products, commonly used can solvent polymer solvent agent material has C.I. solvent agent 黄93, C.I. solvent agent 橙60, C.I. solvent agent 红111, C.I. solvent agent 红135, C.I. solvent agent 蓝104, C.I. solvent agent 绿3 and other.

        5 PS, SAN(styrene — acrylonitrile copolymer), PMMA, PC and CAB and other color agent

         this thermoplastic property plastics tool has excellent transparent property, is make color products maintain has transparent degree, remove can application upper 述一 颜 material product types color outer, more selection tool has high solvent understanding degree solvent agent material and dispersion material, make its in color process in solvent plastics in formed stability separation solvent liquid, high color strong/high degree, 如Macrolex series material (By), product types has MacrolexYellow 6G, Yellow G, Yellow R, Orange GG, Red GS, Red 5B, Red 7B, Violet R, Violet 3R, Violet B, Green 5B, it use amount is 0.025%～0.05%, heat resistant property can to 280～300℃.
