Shanghai Daoqin Plastics Co., Ltd.

plastics Color Matching is in 红, 黄, types basic color upper, 配出令人喜爱, combined color Color Difference requirements, 经济并 in processing, use in color color color. another through Color Matching color also can to certain types application upper requirements.

lower polyethylene wax small belt/tape understanding lower plastics Color Matching tips/techniques, and injection molding products Color Difference solutions.

 

Color Matching is according to plastics property can, molding process, color powder features, color 原则, product requirements and other comprehensive 考虑, for various color powder 进行拼 color, rear to color requirements.

调 color in, 掌握调 deep shallow, color versus, Color Difference is most basic technology.

调 color is deep shallow rear color versus, is deep shallow 一变, color versus 肯定就变.

according to target/goal sample, analysis degree, color versus deep shallow, formed separation in 黑, white ratio/proportion, color color color color color color powder concentrated degree or has light color powder ratio/proportion. for color powder color force can use various color powder in types plastics upper sheet/plate 确认, meanwhile need 掌握每一 types color color material add 入一定 ratio/proportion titanium powder, its color versus and concentrated degree 变化情况.

调 color process in, deep direction, need color light separation is color versus deep concentrated also is concentrated, color versus deep concentrated can again add color powder, concentrated can add black, can add a small amount of add deep color versus deep concentrated.

往 shallow direction, need according to color degree 先确定 good titanium powder use amount, if 不够实 color, need again add titanium powder, meanwhile its it color powder need ratio/proportion add 入, rear according to color versus deep shallow and various color color color agent color force, color color color agent ratio/proportion content.

理论 upper, use 红, 黄, 蓝三原 color can large separation color, is upper, various color agent color is mono pure color, is mono pure color between, belt/tape has versus color color light, ratio 如, color color powder has light and light 红, color color powder has light and light 蓝, color color powder has light and light 黄.

in color process in, need attention/notes color light property, 如调鲜艳 green 时, can use 酞青绿, comparison deep green need light and light 黄 拼 color, can use 互补 红 light and light 黄 拼 color.

deep shallow and color versus rear, basic formulation can 确定, sheet/plate rear and standards for color, rear Color Difference positive. Color Difference and deep shallow, degree, degree, color versus toward has 关.

首先 need Color Difference in 哪 方面, deep shallow use 黑, white powder 调, 明亮鲜艳 degree use increase decrease color powder use amount or add light color powder, increase agent adjustment. color versus toward can increase or decrease/reduce color powder use amount or utilizing color adjustment.

但 is need attention/notes: use color, make color dark.

首先确定 titanium powder content, this is technology key/critical in. is, titanium powder content 一变, color 就会变化 very large, other color powder use amount 就随之改变;

analysis Color Matching Sample color scope/range is 由哪几 types color formed, types is color, types is color, ratio is more. (尽 amount selection and sample color color light versus 近 颜 material, 如调红 color color, Sample 偏黄就 selection large color, 偏鲜艳就 selection or light color color);

most rear Sample degree, is add light color powder or add increase agent.

injection molding products Color Difference what to do

plastics using/adopting injection molding products product types comparison more, application scope comparison 广, Color Difference is injection molding in Common defect.

Color Difference effect/influence factors more, and raw materials resin, masterbatch （ or color powder ）, masterbatch raw materials mixed combined, additives, injection molding process, injection molding machine, mold and other, positive is 牵涉面广泛, therefore Color Difference control technology meanwhile is injection molding in relatively difficult technology 之一.

in production process in generally from below/following 六 方面 进行 Color Difference control.

need selection and injection molding product amount versus injection molding machine, if injection molding machine in material material and other issues, most good more equipment. for/regarding mold system, gas and other formed Color Difference, can through versus separation mold repair solution. must solution good injection molding machine and mold issues can production, decrease issues complex property.

control Raw Materials is solution Color Difference key/critical. therefore, especially is production shallow color products 时, can overlook raw materials resin heat stabilized property different for products color 泽波动 belt/tape obvious effect/influence.
鉴于 large more injection molding production 厂家本身并不 production plastics material or masterbatch, this 样, can will attention/notes 焦点放 in production tube/pipe and Raw Materials upper. add strong/high Raw Materials 入库 检验; production in product can can using/adopting 同一厂家, grade material, masterbatch production;
for/regarding masterbatch, in amount production front need 进行抽检试 color, need upper for, also need in in comparison, if color versus large, can is combined 格, batch masterbatch has light micro Color Difference, can will masterbatch heavy new mixed combined rear again use, decrease/reduce masterbatch mixed combined 不均造 formed Color Difference. meanwhile, also focus/key point raw materials resin, masterbatch heat stabilized property, for/regarding heat stabilized property 不佳, 建议厂家进行调换.

plastics material masterbatch mixed combined good make product color 变化无常. will material and masterbatch machine mixed combined uniform rear, through lower material material 斗时, electrical function, masterbatch material separation 离, easy 吸附于 material 斗壁, this 势必造 formed injection molding cycle in masterbatch amount 改变, from generate Color Difference.
for types can raw materials material rear again add 以人工搅拌 methods solution. for/regarding add color powder production has color product, has most 效 办 method is using/adopting material machine, using/adopting hot drying machine, use add material methods anti color powder material separation 离导致 Color Difference.

production in 常常会遇 to certain add hot loss bad or is add hot control separation long formed material temperature degree 剧烈变化 from generate Color Difference.

this category of causes generate Color Difference very easy 判定, generally add hot loss bad generate Color Difference meanwhile 会伴随 塑化不均 phenomenon, add hot control separation long 烧常伴随 product gas 斑, heavy color 甚至焦化 phenomenon.

therefore production in 需经常检查 add hot separation, add hot separation loss bad or 失控时 and more repair, decrease/reduce this category of Color Difference generate rate.

non Color Difference causes adjustment injection molding process parameters 时, can can 不改变 injection molding temperature degree, back pressure, injection molding cycle and masterbatch add amount, adjustment meanwhile also 需观察 process parameters for color effect/influence, 如发现 Color Difference and adjustment.
尽 can can use high injection speed degree, high back pressure and other strong/high function injection molding process, anti local hot or hot separation understanding and other factors formed Color Difference. control material add hot temperature degree, especially is nozzle and nozzle add hot separation.

in Color Difference adjustment front also must product color temperature degree, masterbatch amount trend. different masterbatch production temperature degree or masterbatch amount 改变, its product color 变化规律 is different. can through color process its 变化规律.
remove non already this type of masterbatch color 变化规律, 否则不 can can very fast good Color Difference, especially is in using/adopting new masterbatch production color 时.
