Using contrast and orthogonal experiment methods , the effect of electrolyte formulae for varied concentration of cr03 and technology of chromium plating on coating property was studied systematically in this paper . primary factors and their interrelations , which influence the brightness of coating , the current efficiency , dispersion ability and sedimentation velocity of electrolyte were discovered 本文采用對比試驗和正交試驗等方法系統地研究了低、中、高三種不同鉻酐濃度的鍍鉻液組成和鍍鉻工藝對鍍鉻層性能的影響,找到了影響鍍層光亮度、鍍液電流效率、分散能力和沉積速度的主要因素及其相互關系。

The suitable additives recombination can not only improve considerably the quality of chromium coating , increase the brightness , current efficiency , dispersion ability and sedimentation velocity , but also enlarge the application scope of chromium plating technology 采用適當的添加劑復合不僅可以顯著提高鍍鉻層質量,增加光亮度、電流效率、分散能力和沉積速度,而且可以擴大鍍鉻工藝范圍。

Different methods are described to measure sludge sedimentation and filtration properties , by use of sedimentation indices , initial sedimentation velocity and capillary suction time ( cst ) 利用沉積作用,最初的沉積作用速度和吸附時間( cst ) ,描述測量爛泥沉積作用和過濾產物的不同方法。
