　　常用色母粒一般包括纖維用色母粒、薄膜用色母粒、電線電纜用色母粒、注塑制品用色母粒、功能化色母粒等。色母粒朝著多功能化、高顏色含量和高技術(shù)含量方向發(fā)展。色母的使用，使顏料在制品中具有更好的分散性，有利于保持顏料的化學(xué)穩(wěn)定性，保證制品顏色的穩(wěn)定，保護(hù)操作人員的健康，保持環(huán)境的潔凈，工序簡(jiǎn)單，轉(zhuǎn)色容易，節(jié)省時(shí)間和原材料。雙螺桿擠出機(jī)以其易操作，低能耗，換色簡(jiǎn)單，廣泛運(yùn)用于色母生產(chǎn)。工藝路線一般包含預(yù)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.
