The mother tablet for a mouthwash may disintegrate in two minutes in warm water below 50°C and after disintegrating, the liquid water can be used to rinse the mouth.
A semiconductor manufacturing technique that can effectively reduce residue of an abrasive agent introduced in a chemical mechanical polishing process, comprises the following steps: a grinding step of using a slurry (30) to grind a surface of a wafer (20); and a rinsing step of using a fluid to rinse the surface of the wafer (20) to remove the slurry (30) residing on the surface.
The rinsing machine swinging spraying device and the method enable both the central position and the edge position of the wafer to have good rinsing effects.
A method for preparing drug-loaded microspheres comprises: providing an emulsifier; adding an organic mixed solution in the emulsifier to form a mixed solution; performing a first stirring step, so that emulsion droplets are formed and dispersed in an aqueous phase of the mixed solution; performing a second stirring step, so that a part of an organic solvent in the mixed solution volatilizes and the emulsion droplets in the aqueous phase of the mixed solution are solidified into solids; performing a separation step to separate the solids from the aqueous phase of the mixed solution; performing at least one rinsing step to rinse the solids using deionized water; and drying microspheres to obtain white solid powder.
(4:5) Also located in the courtyard are ten small copper bowls resting on ornamented copper carriages, and in this water, things having to do with burnt offerings are rinsed.
