        1, how to made plastics products

         need 配一 亮丽 white products, need selection color belt/tape light titanium powder (应 selection chlorine method process production titanium powder, its small, molecular weight distribution uniform), is use color belt/tape light titanium powder made white, to 人们一 types new 鲜感, if selection 一 粒径 large, color belt/tape light titanium powder, using/adopting what method adjustment color light method to pure white.

         titanium powder degree 不够, in plastics color 时往往添 add additives use increase 白. can add non a small amount of and color material or light increase agent increase 白, titanium powder increase 白效果如 lower: commonly used, most simple methods is use 鲜青雕白 block, its increase 白 效果 market upper magnetic 白; use light increase 白效果 most good, its cost most high.

        2, how to made plastics products

         in use 炭黑配 made products 时应该 attention/notes black light issues. in light lower, usually small ratio large more color 调, in light lower (transparent color) and color is color 调. to 一 乌黑 light plastics products, selection small low structure 炭黑. this is is color 时, degree main/primary for light absorption therefore 粒径越 small, light absorption degree high, light 反射越 low, degree high. selection upper 述炭黑 product types, obtain color 效果, especially attention/notes dispersion property. has solution dispersion property, can to most high color force.

        炭黑经 oxidation rear, 引入极 property 基团如—OH, —COOH, improve/increase dispersion property, therefore in property can indicators in has volatile content indicators, its value high, oxidation degree high.

        无论 how to 炭黑总 belt/tape has 一 黄 light, therefore can use 蓝进行调 color, its use amount is 8%~10%, this made black degree large is increase. using/adopting generally is material 蓝15∶ if using/adopting color agent color rear upper again use color or color color, its made 黑 乌黑 degree 也许会 more 黑.

        3, how to made color plastics products

         use 炭黑配 made color 时应该 attention/notes black light issues, 炭黑粒径 small, add titanium powder 时呈现 belt/tape color color 调 灰 color;炭黑粒径 large, add titanium powder 时, to belt/tape color color. titanium powder large small and distribution and titanium powder light has very large 关系, titanium powder large belt/tape light, small belt/tape light. therefore made color need 搞清炭黑 and titanium powder and color 调 关系, color 调搞错, again use material adjustment, 会越调越 complex.

        灰 color products Color Matching in 确定 炭黑 and titanium powder rear, has also need use its it color color to use requirements, due to material add amount less, therefore selection color force low product types, oxidation iron (颜 material 黄119, material 红101), metal oxidation material (颜 material 黄53, material 棕24), this can make Color Matching system color stability property more good.

        4, how to made outer use plastics products

        (1) deep color outer use plastics products.

         plastics products how to 体育场 椅子, large 桥 钢缆护 sleeve/set, construction use 材, 广告箱, turnover box, plastics automotive parts and other, long in outer use, therefore must requirements has good lightfast and weather resistance. machine material generally has good light stabilization property, can used for outer use plastics products Color Matching, color force low to made.

        配 made outer products 时首先 need selection lightfast, weather resistance good color agent, its in products in amount less use or use titanium powder, make material concentrated degree in products in can can high. another, in color formulation in has amount outer absorption agent and antioxidant ensure resin color. outer use plastics products selection has machine plastics.

        (2) shallow color outer use plastics products.

         shallow color plastics products through add a large amount of titanium powder and a small amount of material made formed, due to large more has machine material add titanium powder rear weather resistance, heat resistant property has different degree decline, shallow color product types material add amount less, its effect/influence more large, less product types weather resistance good, formed plastics products color, 客户投诉, effect/influence bad. has machine material color force high, therefore used for shallow color product types in add amount less, 因误差传递会造 formed production in Color Difference, use has color 偏差.

         shallow color product types selection machine material made, main/primary utilizing its heat resistant property good, color force low advantages. can selection machine material is material 黄119(oxidation iron), material 黄53(metal oxidation material), material 棕24(metal oxidation material), material 棕184(钒 acid 铋), material color 01(oxidation iron), material 蓝29(群青), material green 8(钴蓝), material 棕50(钴绿).

        5, how to made transparent plastics products

        配 made shallow color transparent products resin is transparent color, polypropylene (PP) and transparent styrene. need selection transparent degree good, color light color agent. generally 而言, machine material transparent property good can application, in has machine material in transparent property good product types is: material 黄花139(异吲哚啉 ketone), material 黄199(蒽醌), material 红149(苝系), material 红254(二 ketone -吡咯-吡咯), material 蓝15∶1(酞菁), material 绿36(酞菁), material 棕41(shrink combined nitrogen).

        6, how to made light plastics products

        珠 light material in plastics injection molding product in add ratio/proportion generally is 1%; in extrusion film type product in is 4%~8%, specific according to plastics film thick degree 而定;同样 in extrusion composite/compounding 时, light in light content need versus improve/increase, according to plastics light thick degree, add amount is 5%~10%.

        (1) attention/notes light material and has machine material selection. in plastics processing process in use light material generally need attention/notes below/following 几点:

         by color resin transparent property need good;尽 can can selection transparent property good material (如 has machine material) and solvent agent material;不 can and titanium powder 配伍, is to 一定 遮 cover/cap force, can meanwhile use small 粒径 珠 light material, amount use high cover/cap force material;珠 light material application in outer plastics products upper 时, need 考虑珠 light material weather resistance.

        (2) attention/notes light material processing molding process.

         injection molding improve/increase back pressure, improve/increase screw mixing/compounding property, from improve/increase light material dispersion property, injection molding processing temperature degree generally in resin recommendation use temperature degree scope/range upper 限处, this can ensure light powder dispersion property, in molding process in, melt flow belt/tape 动 珠 light material sheet/slice 晶 自动定 toward, 取 良 good light 效果.

         mold surface light degree is non important. mold light 洁, can to direction and light slip light color 泽.

         mold gate design is non important. selection mono gate ratio more gate more can decrease/reduce 模口流出线, gate usually selection in flow thick 实处, gate and runner system between 距离应尽 can can small, decrease/reduce due to retardant force 差异而引起 珠 light material distribution non-uniform and 杂乱无章 排列 phenomenon.

         due to light material sheet/slice in, in plastics processing process in, due to force effect/influence, material 粒径会变 small, light 效果会 reduce. using/adopting relatively large long ratio and fine degree 滤网以 increase machine pressure, can can decrease/reduce processing process in force for light material bad.

         in PMMA, PC, PA system in use light material, must 事先进行 drying 处理.

         in PVC plastics in, use color and copper color light material series product 时, due to has iron 离子, accelerated PVC resin separation understanding, use must attention/notes. white light material in has material product in 会泛黄, recommendation use resistant yellowing series product.

        7, how to made 金, color plastics products

        银 powder upper is aluminum powder. due to aluminum surface can strong/high 烈 反射包括蓝 color light in inner can light 谱, therefore aluminum material can generate very 亮 蓝-白镜面反射 light.

         aluminum powder in plastics in application has different product types. material 平均直径5 μm, its color force and cover/cap force good; pellets 平均直径20~30 μm, can and color color material use; pellets 平均直径330 μm, tool has coarse 闪烁效果.

         aluminum powder melting point is 660℃, in high temperature lower and gas 接触时, surface by oxidation formed white, therefore for aluminum powder surface treatment has oxidation silicon film, can make its tool has heat resistant, weather resistant, resistant acid property.

        金 powder is copper powder, its in high temperature lower easy oxidation. its resistant property good, long time in outer 也会发 dark. in copper powder surface using/adopting technology make its has oxidation silicon film, can large large improve/increase its heat resistant property, weather resistance and resistant acid property. Germany ECKART company provide RSIST grade powder oxidation silicon 处理, using/adopting its raw materials made color masterbatch in high temperature lower injection molding has dark phenomenon.

         is made metal 效果, can add a small amount of transparent property relatively good, color light versus has machine material, need attention/notes is: if in formulation in add more titanium powder and light powder type material 质, make products dark.

         due to powder and powder sheet/slice structure, therefore use metal material and light material in injection molding processing in relatively easy generate 模流出线, effect/influence plastics product appearance. can using/adopting lower methods decrease/reduce or reduce upper 述情况: using/adopting large metal material; improve/increase metal material add amount; selection degree high resin; add large injection 孔径; increase injection speed degree.

        8, how to made light plastics products

         plastics upper use light material is will light material dispersion in polymer/macromolecule resin in made formed, make light material 不会发生迁移. from 1970 year use complex system polyamide (PA) resin make light material heat stabilized property can 达305℃, development polyester is 载体 荧 light material obtain formed 功, its heat stabilized property can 达285℃ above.

        荧 light material for outer 线敏感, therefore lightfast property relatively 差. improve/increase light products lightfast property methods is add same color non light color agent.
