Abstract: The present application provides a method for preparing a powder cosmetic with a gradient color effect and a powder cosmetic. The method comprises the following steps: mixing; color laydown: providing a mold having at least one cavity with an upward opening; taking at least one water-soluble pigment, diluting them separately to obtain at least one pigment solution, and dot-coating the at least one pigment solution onto at least one preset position on the bottom of the cavity; filling; freezing: freezing the material system within the mold at a low temperature to obtain a powder masterbatch; demolding: separating the powder masterbatch from the mold; drying: drying the demolded powder masterbatch to obtain a powder cosmetic with a gradient color effect; wherein the concentration of the pigment solution is from 0.1% to 10% by mass; and the viscosity of the mixed material system at 25° C. is from 1000 to 15000 cP.

Abstract: The present application provides a method for preparing a make-up powder block having a spot-dyeing effect and a make-up powder block. The method comprises the following steps: preparing a powder base material; preparing a spot-dyeing base material, and mixing the spot-dyeing base material with a water-insoluble coloring material to obtain a spot-dyeing material; applying the at least one spot-dyeing material in dots onto at least one preset position on the bottom of the cavity; filling the mold after dot application with a predetermined amount of the powder base material; freezing and demolding the mixed material within the mold; freeze-drying the demolded powder masterbatch to obtain a make-up powder block having a spot-dyeing effect; wherein the powder base material and the spot-dyeing material exhibit fluidity at normal temperature and pressure.

Abstract: The present application relates to a process method for improving the quality and stability of powder products, at least comprising: preheating a mold, filling, bottom vibration with a grid, cooling, microwave drying, pre-freezing, demolding, freezing, sublimation drying, and baking. The prepared powder products exhibit an exquisite appearance, and are suitable for the production and manufacturing of powder cosmetics.

Abstract: Disclosed are an apparatus for cooling a server cabinet and a server cabinet apparatus. The apparatus for cooling a server cabinet includes: a bracket a heat-exchange device, and an air-ducting device; where the bracket is positioned below one or a plurality of server cabinets, the heat-exchange device is installed on a side surface of the bracket, the air-ducting device is installed in the bracket, the heat-exchange device and the air-ducting device are parallelly arranged, the heat-exchange device cools hot air produced by the server cabinet to obtain cold air, and the air-ducting device blows the cold air to the server cabinet to cool the server cabinet. The server cabinet apparatus includes: an apparatus for cooling a server cabinet and at least one server cabinet. With the apparatus for cooling a server cabinet, each of the servers in a data center are effectively cooled, and resources are saved.
