By simulated test, the co-relationship among the slip granulometric composition, slurry deflocculation curve, mid-high pressure casting forming speed and green body shaping endurance is studied.
The expansion mechanism of hydroxide expanding phase for oil well cement slurry are discussed on the basis of principle of chemical thermodynamics and topochemical reaction model.
The operation of the slurry pumps for transferr in g sludge in the dilute phosphoric acid defecator in the phosphoric acid producti on is mostly not satisfactory.
When drill hole in sandy soil the desander should be timely turned on to reduce the sand content and ensure the drilling progressing and stability of the hole.
The turbulator can be used to improve the centralization of the casing strings, to allow the fluid to form spiral flow, as well as to improve the displacement efficiency.
