Cr3C2-25%NiCr料浆中分散剂含量对其喷雾干燥粉末性能的影响
EFFECT OF DISPERSANT CONTENT IN Cr3C2-25%NiCr SLURRY ON POWDER PROPERTY PREPARED BY SPRAY DRYING
【摘要】 通过添加高分子分散剂配制Cr3C2-25%NiCr料浆,喷雾干燥制备出高球形化的Cr3C2-25%NiCr复合粉末。利用SEM研究了分散剂含量对喷雾干燥制备的Cr3C2-25%NiCr复合粉末性能的影响,结果表明:分散剂能够调节料浆性能,粉末的流动性及松装密度明显提高,其中0.04%含量的分散剂所制备的Cr3C2-25%NiCr粉末具有最佳的物理性能。
【Abstract】 In this research,the spherical shape composite powder was prepared with spray drying through adding a type of high polymer dispersant in Cr3C2-25%NiCr slurry.The experiment researched the effect of dispersant content on the characteristics of Cr3C2-25%NiCr composite powder by means of SEM.The result indicats that the properties of Cr3C2-25%NiCr slurry are accommodated obviously,and that the pourability and loose density of powder are increased.When the content of dispersant is 0.04%,the powder is of best physical properties.
