Process and apparatus for producing elementary nanoparticulate mineral components and rare metal oxides therefrom using primary and secondary mineral resources by filling raw material (1,15,16,17) into a mixing tank (7), wherein it is diluted with water to a 20% by weight colloidal solution, then the colloidal solution is fed to a colloid mill (8) and dispersed into particles having an average particle size of up to 10 µm, then transferring it to a wet grinding attritor (9), the nanoparticulate colloidal solution thus obtained is passed under pressure to a classifying unit (10) in which its nanocrystallite content is separated into at least two size fractions, each size fraction being dried in a vacuum drier (11), while a further nanocrystallite fraction containing trace elements is separated by the vacuum drier (11), which is passed to a separator (13,11a) where adsorbed rare metal trace elements are separated.
The present invention relates to a core-shell heat storage microcapsule having a core containing a phase change heat storage material and a coating of amorphous glassy alginate, which coating has at least two layers and at least one layer contains nanoparticles, and the surfaces of the core and the coating are in direct or spaced contact, and the microcapsule core has a solid or internal cavity.
The present invention relates to an additive for carbon nanotube and plastic composites comprising a functionalized maleic acid anhydride-olefin copolymer, wherein the maleic acid anhydride monomer units are partially or completely converted to dicarboxylic acid ester amide and / or dicarboxylic acid half ester and / or dicarboxylic acid imide monomer units, wherein the number of maleic acid anhydride monomer units of formula (I) is from 1 to 1 to 8. The invented composite can be used, for example, for the production of heavy-duty plastics, aircraft and vehicle body components, structural materials replacing high-strength metal parts, building cladding and components, insulation materials, electrical and thermal coatings, sealants, furniture components, high-strength nets and ropes.
The invention relates to the low molecular weight compatibilizing additive package having many advantageous effects, which improves the compatibility of different thermoplastic and/or thermosetting polymers and/or fillings, functional additives just as composites containing natural and/or artificial strengthening fibres, and relates to its preparation and application processes.
The present invention relates to a dry-fuel heat-storing apparatus for storing and economically using the thermal energy produced in a combustion apparatus or other heat sources, wherein the heat-storing apparatus is operable at high temperatures.
