Shanghai Daoqin Plastics Co., Ltd.

  plastics Color Matching 专业人员面 for provide sample using/adopting lower steps Color Matching.  
according to to conditions 包括 plastics types type, plastics products applications, plastics molding process. its in plastics products applications also lightfast property and weather resistance, property, cover/cap force, transparent property, resistant aging property, property (heavy metal), food 卫生(FDA), resistant acid alkali property, resistant solvent agent property, force strong/high degree, thermal properties, electrical property can and other.  
setting project 包括 color agent 形状, Color Matching, color agent  
selection (包括添 add amount, color agent product types selection), design formulation, Color Matching experiment/testing, Color Matching color agent product types selection weather resistance, dispersion property, 形变, property, property, hot property, safety property, color cost.  
1, understanding sample requirements  
(1) sample plastics types type; 
(2) sample plastics applications; 
(3) sample molding process.  
according to above conditions can understanding product selection color agent need meet/satisfy requirements (heat resistant property, lightfast property, weather resistance, resistant property, safety property). in addition, Color Matching also need for requirements color agent agent type 予以确认(颜 material dry powder, color masterbatch , 砂状, modified material), for requirements color ratio/proportion (添 add amount)予以确认.  
2, according to requirements 进行初步 formulation design  
(1)颜 material selection. according to sample transparent, transparent also is semi transparent selection color agent.  
(2) color cost comprehensive amount. cost is non important amount factors, 颜 material price 跟颜 material property can important.  
(3)拟定出初步 formulation. through research rear, from color 调, degree, concentrated and other 方面反复 comparison and standards color and 参照 差别, in 此基础 upper for material color agent formulation 进行修 positive, 拟定出初步 formulation. in 无参照 material lower, fine analysis plastics products (sample) color color light, color and degree and other, color property, rear according to 孟塞尔 color system Color Matching, 并拟定 by formulation.  
3, 反复调 small amount 接近客户 样 
currently enterprise using/adopting plastics methods upper is method, tool has separation property, 但至今 in plastics industrial Color Matching in also is separation can, is large separation enterprise using/adopting.  
Color Matching according to 拟定 初步 formulation 进行实 material color experiment/testing, will made color and standards color and material 一起进行 comparison, 进一步 adjustment color formulation. rear according to adjustment rear formulation again made Sample comparison.  
4, color comparison  
Sample and provide sample color comparison is Color Matching 一 十 separation important step/link. according to sample made as process made as sample comparison, film product using/adopting film method comparison, injection molding product using/adopting injection molding method comparison, fiber product using/adopting filament method comparison.  
(1) light effect/influence. 目测时 light most good using/adopting light, has conditions   can using/adopting standards light 源箱, in certain light lower comparison 观测两 sample color can can is “同 color 异谱” phenomenon make color 看起 似乎 same, in light lower has relatively large Color Difference.  
(2) thick degree effect/influence. different thick degree products to 人眼 感觉不一样; thick degree small relatively light, color shallow, Color Matching 时应尽 amount make Sample and sample thick degree 一致, method is can large 概推测一 lower.  
(3) surface effect/influence. different surface its light 线反射 different, in sample upper, high gloss surface formed light surface color to different 感觉, sample upper, 毛糙面就 relatively light slip deep, dark, ratio color 观测时 need can can use surface versus 近 部位进行 comparison.  
(4) resin effect/influence. 同一颜 material application in different resin in its color 不一, this is due to resin natural color color and transparent property 不一引起, therefore Color Matching attention/notes amount using/adopting provide resin Color Matching ensure color 泽 准确 property, especially is modified material Color Matching more attention/notes.  
(5) ratio color 判断错误.  
in for process in most easy issues is ratio color 判断错误, 判断错误 main/primary is experience 不足引起, usually can 由平时不断练习, 不断丰富 experience solution, use 一 仪 device ratio color and other can has positive 确 判断.  
5, color 异谱 
一 for sample different color agent made. it in light 源照射 lower, 由特定观察者观察时, color is 匹配. if lighting 发生变化, material will again 匹配. color phenomenon very Common, has 时令人不愉 fast, color can make many different 颜 material Color Matching formed is can can. has color agent can use color agent 代替. color agent can use color agent 代替以 reduce cost. due to color phenomenon in, use different color agent heavy new to formulation is can can. Color Matching can in color in 赋予一 products 坐标, make it color 匹配, tube/pipe it is different color agent made.  
消 remove material conditions Color Matching phenomenon methods is use same color agent.
