Effect on the flocculation sedimentation velocity in different conditions of cation concentration by concentration of sediments particles 不同離子濃度下泥沙濃度對(duì)絮凝沉降的影響
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(shí)間( cst ) ,描述測(cè)量爛泥沉積作用和過濾產(chǎn)物的不同方法。
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(dāng)?shù)奶砑觿?fù)合不僅可以顯著提高鍍鉻層質(zhì)量,增加光亮度、電流效率、分散能力和沉積速度,而且可以擴(kuò)大鍍鉻工藝范圍。
