Objective: To compare the clinical effects of calcium hydroxide iodoform (CHI) slurry and traditional intracanal medication such as formocresol (FC), camphophenic (CP).
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.
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 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.
The features of coal-water slurry and heat coal gas,and its process,invest and budget,profit and technology feasibility by the two kinds of fuel instead of masout were introduced.
Meanwhile, CMP slurries are continually flushed with water to keep their fine particles from forming chunks that would tear apart the fragile copper lines.
