large more material is according to 特定 粒径 dimensions production, usually can through coating material manufacturing 商 额 outer abrasion modified. 颜 material 粒径 large small effect/influence material color and property, therefore understanding material is coarse separation also is fine separation non has use.

粒径 is material or coating material features several important causes. in different material in, relatively small 粒径 颜 material usually tool has below/following 特征:
• color force more high, is in same weight （ quality ） 颜 material in, more small generate more large surface 积, in same in generate more strong/high color;
• more transparent, is more high color strong/high degree use more a small amount of material;
• more easy color, is relatively small material more easy by color material internal in.

in types material in, relatively small 粒径（ low 至约0.5μm dimensions or light long ）倾 toward saturated and degree relatively low value relatively light material 特征, is relatively small dimensions generate surface increase, increase same amount material surface dispersion 射. in combined formed has machine material in, relatively small material pellets usually comparison large pellets same material lightfast property 差; in material material in, this type of 效果不太 obvious.

in and acrylic resin in, relatively small dimensions make material more transparent, to more high saturated and degree, is pellets full drying paint in, from decrease/reduce pellets surface light dispersion 射. in water color in, relatively small material more transparent, is same amount pellets cover/cap surface more less, from 而允许 more more 纸张（ or lower paint 层）显示出. through dilute color, make is transparent paint can more transparent, this in used for 纸张 颜 material pellets between generate more more can 见 空间.

usually, material color 调也会随颜 material large small 而变化, has 时会发生显 变化. need to this 一点, can in mixed combined in mixed combined a small amount of 钴绿（颜 material 绿50）, 静置 夜, rear large separation liquid 体, micro surface color will is shallow color in property color, this is most rear from solvent liquid in 沉淀出 most small pellets color. use in-depth material, 你会发现颜 material pellets relatively heavy, color also is (more more strong/high 烈)青 green.

basic upper paint company has 自己 颜 material dimensions standards, this not only is is more fine material can has more color, but also is more and other grade, need more more electrical can and force abrasion, and usually lightfast. this is is what tool has same color 指数名称 颜 material can tool has different lightfast property.

most rear, material 粒径会 effect/influence coating material property. usually relatively small material pellets more easy 发生回流. also need add dispersant, 例如牛胆汁, in abrasion process in full lubricating wet （ dispersion ） paint in material powder 末, this type of additives 会导致颜 material in wet coating 时积极 expand dispersion.
