A method for producing the inventive composition, the use thereof for producing a layer or coating consisting of layers or coatings obtained from said composition and objects coated at least partially with said layer or coating are also disclosed.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren zum Reinigen einer Membran (3), die zum Filtern von Wasser dient, zum Beispiel zur Aufbereitung von Trink- und/oder Brauchwasser, bei dem ein Reinigungsmittel (34) auf eine Oberfläche (33) der Membran (3) aufgebracht wird, wobei das Reinigungsmittel (34) eine wässrige Hypochloritlösung (39) aufweist, die mit einer Säure (40) aktiviert ist, derart, dass ihr pH-Wert kleiner 7 ist.
摘要:
The invention relates to a filtration device for effluent purification, preferably for a sewage treatment plant, in particular, for a small sewage treatment plant, comprising at least one ceramic-based membrane for separation of microorganisms, a sewage plant with such a filtration device, a method for purification of effluent, in particular in a sewage plant, wherein microorganisms in the effluent are separated by means of at least one ceramic-based membrane and the use of a ceramic based membrane as filter for separation of microorganisms and optionally fine solids from effluents.
摘要:
Nano-sized delivery systems consisting of an inorganic nano particle moiety covalently bonded to at least one organic pro-perfume or pro-drug moiety are disclosed. The systems of the invention are able to deliver perfuming or pharmaceutical active ingredients. Other aspect of the present invention, for instance, are the use of said systems in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's delivery systems.
摘要:
The present invention relates to a method for removing radioactive nuclides from water, which uses at least one absorption additive (15) having an absorptive effect on the nuclides, and at least one filter device (7, 8), which is impermeable to the adsorption additive (15) and nuclides absorbed thereon. An adsorption layer (20) produced from the adsorption additive (15) on an inflow-side surface (19) of the filter device (7, 8) results in an improved removal rate at reduced apparatus outlay.
摘要:
The invention relates to the use of a composition comprising a nanoscale powder, a porous ceramic powder, and a solvent to protect a metallic surface against chemical attacks at high temperatures, in particular in reducing and/or carburizing atmosphere, and to a corresponding method. The invention further relates to a system part that comprises a metallic surface that is exposed to a reducing and/or carburizing atmosphere in the operating state, wherein the surface is coated with a porous protective coating that has a specific surface area of at least 20 m 2 /g.
摘要:
The invention relates to a method for the production of molds for casting purposes, and parts of the same made of a granular, fireproof material and a binding agent, particularly shell molds, sand cores, and parts thereof. For this purpose two devices are utilized having parts, onto which a composition is applied before the use thereof, said composition comprising at least one silicon-organic component. The invention further relates to the use of such a composition for the production of molds for casting purposes, and to a corresponding device. The latter is characterized in that it comprises at least one part that is equipped with a silicon-organic layer or coating.
摘要:
The present invention relates to a coat or coating to counteract crystalline deposits, said coat or coating being on a substrate and comprising a matrix composed of a binder system and ceramic particles and also boron nitride in particulate form, the boron nitride particles being embedded and essentially uniformly dispersed in the matrix; to a composition for producing such a coat or coating; to a process for producing such a coat or coating; to the use of a boron nitride composition as a material for coating surfaces coming into contact with salt-containing solutions; and also to a water treatment plant comprising components coming into contact with salt-containing water and provided at least partially with a coat comprising boron nitride.
