常用色母粒一般包括纤维用色母粒、薄膜用色母粒、电线电缆用色母粒、注塑制品用色母粒、功能化色母粒等。色母粒朝着多功能化、高颜色含量和高技术含量方向发展。色母的使用，使颜料在制品中具有更好的分散性，有利于保持颜料的化学稳定性，保证制品颜色的稳定，保护操作人员的健康，保持环境的洁净，工序简单，转色容易，节省时间和原材料。双螺杆挤出机以其易操作，低能耗，换色简单，广泛运用于色母生产。工艺路线一般包含预混和分布喂料。Color masterbatches generally include color masterbatch for fifiber, color masterbatch for fifilm, color masteru0002batch for wire and cable, color masterbatch for injection molding products, functionalized color masterbatch,etc. The color masterbatch is developing in the direction of multi-function, high color content and high technology.The use of color masterbatch makes the pigment have better dispersibility in the product, which is benefificial tomaintain the chemical stability of the pigment, ensure the color stability of the product, protect the health of theoperator, keep the environment clean, the process is simple, and the color changing is easy, saving time and rawmaterials.The twin screw extruder is widely used in the production of color masterbatch due to its easy operation, lowenergy consumption and simple color changing. Process routes typically include premixed and multi-feeding.
