摘要:
Speriodal polymer beads having a uniform size are prepared by polymerizing uniformly sized 5 monomer droplets formed by dispersing a polymerizable monomer phase over double-walled cylindrical cross-flow membrane into an suspension phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the suspension phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The membrane is metallic and includes a superhydrophobic coating.

The invention relates to a coating device (100) with movable spray nozzles comprising a rotating drum (3) and positioning group (1) of a set of spray nozzles (21) for a product with a control column (5) able to be located essentially axially inside the drum (3) and which houses an inner shaft (6), the control column (5) being equipped with at least an articulated arm (7) that includes a rotating nozzle set (21) carrier (20). A transmission system (30) based on pulley means and corresponding pulling means housed in the control column (5) and in the articulated arm (7) simultaneously produce the contraction or extension of the articulated arm (7) and the rotation of the nozzle set (21) carrier (2) based on the relative angular position between the steering column (5) and the inner shaft (6).

Provided are three-tank automatic particle production method and system. The method comprises: feeding material to be treated into a heating tank in batches during idle of the heating tank; heating and stirring the material in the heating tank under a preset heating temperature for a first preset time to obtain a first intermediate material; connecting an outlet of the heating tank to an inlet of a baking tank, feeding the first intermediate material in the heating tank into the baking tank, and disengaging the outlet of the heating tank with the inlet of the baking tank.

The present invention relates to an apparatus for coating carrier particles with guest particles. The apparatus comprises a cylindrical processing vessel rotatable about its axis and having solid walls defining a chamber for receiving the particles, and a hollow shaft extending within the chamber at least partly along the axis of the cylindrical processing vessel, the hollow shaft defining a gas flow path connected to a gas inlet. The hollow shaft comprises one or more axially-extending slots or one or more axially-extending rows of apertures allowing fluid communication between the gas flow path and the chamber. The apparatus may be used in a process for coating carrier particles with guest particles, the process comprising: adding the particles to the chamber defined by the cylindrical processing vessel; rotating the cylindrical processing vessel about its axis; and flowing gas from the gas inlet along the gas flow path in the hollow shaft and into the chamber through the one or more axially-extending slots or one or more axially-extending rows of apertures.
摘要:
It is an objective of the present invention to provide a mechanomechanical device improving the quality of the analytical measurements done by diffraction or other analytical techniques (e.g. spectroscopic ones) during ball milling processes. This objective is achieved according to the present invention by a mechanochemical device (2) for mixing and/or reacting at least one chemical compound to at least one reaction product (4), comprising: a) a grinding container (6) having a milling chamber (7), milling elements (8) and at least one probing chamber (10) wherein the at least one probing chamber (10) is realized as a recess volume (12) of said milling chamber (7) and wherein the recess volume (12) has a cross-sectional opening towards the milling chamber (7) that is smaller than the dimensions of the milling elements (8) preventing the milling elements (8) from entering into the recess volume (12); and b) a motor (14, 16) coupled to the grinding container (6) in order to rotate the grinding container (6) thereby bringing the recess volume (12) at least temporarily into a position allowing a gravitation driven release of the at least one compound and/or the at least one reaction product (4) that entered the recess volume (12) back into the milling chamber. This device enables measurements done in a small part called probe chamber being specifically designed for analytical techniques. The features of the present invention make sure that the reaction product and/or its precursors (the ration strongly depends on the progress of the reaction of the precursors) is quasi-permanently present in the probe chamber which allows for an quasi-permanent analysis on the progress/evolution of the desired mechanochemical-induced reaction.
