摘要:
An anti-fouling system (1) for use with a wet compartment (10) having at least one inlet opening (11) for allowing water to enter the compartment (10) is configured to receive and operate at least one anti-fouling source for emitting anti-fouling light in order to keep at least one surface (26) as present in the compartment (10) free from biofouling. The system (1) comprises a controller (50) for controlling operation of the at least one anti-fouling source (30), the controller (50) being configured to determine at least one operation parameter of the at least one anti-fouling source (30) in relation to at least one of at least one water-related parameter, at least one surface-related parameter and at least one opening-related parameter.
摘要:
The invention relates to a device for cleaning plastic in the course of plastic recycling, comprising a refiner (10) having two refiner tools facing each other, of which at least one is rotationally driven and which bound a working gap between each other, wherein the refiner has an inlet that opens into the working gap, and comprising an input apparatus connected to the inlet for inputting the plastic to be cleaned into the inlet, wherein the refiner has an outlet, which is likewise connected to the working gap and through which the plastic is led away to an exit, wherein the outlet comprises an outlet pipe (20), which is connected to the working gap and leads to the exit, wherein the outlet pipe is connected to a water pump (32), wherein the water pumped through the outlet pipe by means of the water pump has a suction effect on the working gap during operation, in such a way that cleaned plastic is conveyed from the working gap into the outlet pipe. The invention further relates to a corresponding method.
摘要:
Processes and compositions for cleaning mixing devices are disclosed that improve the production and quality of polycarbonate resins subsequently produced in the mixing device, while reducing the time needed for cleaning and/or change over. A cleaning mixture comprising polycarbonate resin pellets coated with an alkyl aryl sulfonate salt aqueous solution are used to purge the mixing device.

Machine for containing a primary fluid using a secondary fluid with a boiling point below that of the primary fluid. The machine particularly comprises a primary vapour cooling system in the form of a heat exchanger (11) located between the primary vapour and the secondary fluid (12) and provided with discharge ports (15) for releasing the secondary vapour into the vessel (4) so that the exchanger condenses the primary vapour and vaporises the secondary fluid, thus providing thermal self-stabilisation within the vessel.
摘要:
L'invention se rapporte à un procédé qui sert à nettoyer un miroir réflecteur dans un appareil optique mesurant le point de rosée ou la température de gel d'un gas échantillon et qui consiste à amener le gaz échantillon en contact avec le miroir réflecteur dont la température est variable, à projeter des rayons condensés de lumière ou de rayonnement laser sur le miroir réflecteur, et à détecter la variation d'intensité de la lumière diffusée et/ou de la lumière réfléchie en raison de la rosée ou du gel qui se forme sur le miroir réflecteur. Ce procédé se caractérise en ce qu'on place du CO2 ou un gaz contenant du CO2 en contact avec le réflecteur, pendant que ce dernier se trouve à l'état refroidi, ce qui crée une condensation du CO2 à la surface du miroir réflecteur, et en ce qu'on procède à l'échauffement du miroir réflecteur en vue d'obtenir une vaporisation du CO2.

摘要:
Objects with complex surface profiles can be cleaned effectively using hyperbaric pressures. A high temperature high pressure liquid or vapor can be introduced to a sealed chamber containing an object to be cleaned, forming a thin liquid layer on the object. The pressure in the sealed chamber can be quickly reduced, evaporating the thin liquid layer, which can remove surface contaminants from the object. The process can be repeated until the object is cleaned.
摘要:
In one or more embodiments described herein, there is provided an apparatus for a user interface, the user interface including a user interface surface, the user interface surface including at least part of a self cleaning composition, the composition being configured to draw away at least one dermatological contaminant from one or more contaminated regions of the user interface surface to thereby provide a self-cleaning user interface surface.
