   in color masterbatch production field/area in, add wax and polyethylene wax can improvement polymer material material system flow property, through improvement material and other additives lubricating wet property and dispersion property different degree improvement processing properties has improve/increase production efficiency, and extrusion products table/sheet gloss property good. therefore has very more use melting point 60℃ left right wax as is dispersant use or and polyethylene wax use, improve/increase output/production volume, reduce cost. in 我们以 color masterbatch processing application 视角 观察二者 property can 差异.

         （1） thermal properties

         used for color masterbatch lubricated dispersant, must can in color masterbatch manufacturing and color products molding relatively good processing temperature degree, maintain material material heat stabilized; 否则, gas or separation understanding dispersant for color masterbatch or products property can formed defect effect/influence. color masterbatch and products processing temperature degree generally in 160-220℃ between. for polyethylene wax and melting point is 60℃ 石 wax and and other temperature hot heavy 实验, 结果发现, in 200℃ below/following, wax in 4min inner 就推动 weight 9.57%, 10min inner weight loss 失达20 %. from heat resistant property degree 而言, polyethylene wax can performance very good resistant thermal properties, wax difficult ensure, wax is combined use color masterbatch dispersant.

        （2） dispersion property can

         is comparison polyethylene wax and wax dispersion property can, separation for 二者以 different concentrated degree made formed black masterbatch, film degree experiment/testing. 实验结果发现: in 0 -7％ 添 add ratio/proportion in, black masterbatch polyethylene wax content increase, film degree upper rise 36.7%, polyethylene wax content high, dispersion property can good; however in 同样 添 add ratio/proportion in, black masterbatch 随 石 wax increase, film degree decline 19.9%, 说明石 wax content high, dispersion property can 越差.

         this is is and polyethylene wax versus ratio, wax more easy lubricating wet 炭黑, meanwhile make system viscosity large degree reduce. low viscosity large large low force 传递, make dispersion to dry 扰, by wax surface 包覆而形 formed relatively large pellets 炭黑团 poly 体, 显然, this type of retardant dispersion function large large ultra- its low poly inner poly force function. therefore 实验结果 comparison 说明, polyethylene wax for tool has very good lubricated dispersion function, in color masterbatch in, add wax 炭黑会 significantly 变差.
