摘要:
The present invention relates to a method of specifying a batch, lot, or shipment of particulate material by using at least one interfacial potential property value to specify the batch, lot, or shipment of particulate material. A method of representing a grade, brand, or type of particulate material is also disclosed. At least one morphological value and/or chemical value may also be included. The values can be included on a product specification sheet.
摘要:
The present invention relates to a method of selecting and/or developing particulate material for a composition comprising the particulate material and a matrix by using at least one homogeneous interaction parameter alone or in combination with at least one heterogeneous interaction parameter. These parameters may comprise at least one interfacial potential property value, at least one value derived from an interfacial potential property value, at least one component of an interfacial potential property value, or combinations thereof for a particulate material and for the matrix. Process and performance maps, as well as methods for mapping, are also disclosed.
摘要:
The present invention relates to a method of providing product consistency of a particulate material or the product containing the same, by measuring and/or analyzing at least one interfacial potential property value of the particulate material. The method may be used as a QA/QC method to insure product consistency.
摘要:
Carbon blacks which are useful in a variety of polymer compounds including ABS compounds are described, as well as methods of making the carbon blacks and polymer compounds. The carbon blacks provide desirable jetness and impact strength, as well as good dispersion in a polymer.
摘要:
The present invention includes metal oxide foam particles and a method of making the same. A decomposable metal salt feed solution is injected into a hot atomizing gas. The mixture of hot atomizing gas and feed solution is maintained in the reactor until the feed solution converts to metal oxide foam particles. The metal oxide foam particles have a high specific surface area.
摘要:
Silicone rubber compositions are disclosed including a silicone polymer and a silicon-treated carbon black. The silicon-treated carbon blacks include a silicon-containing compound that is distributed through at least a portion of the carbon black aggregate. The silicon-treated carbon black is incorporated within a silicone rubber composition as an alternative reinforcing and extending filler, imparting higher hardness to elastomers formed from the composition, when compared to silicone rubber compositions incorporating an untreated carbon black.

A method for producing fine magnetic particles having the barium or strotium ferrite M-phase crystal structure. An iron and alkaline earth metal halide feed solution is vaporized to form a precursor and oxidizing vapor phase. The precursor and hydrolyzing or oxidizing vapor phases are held in a reactor at a temperature sufficient to effect vaporization of the feed solution yet which is below the melting point of the desired M-phase crystal structure. Small iron oxide particles precipitate from the vapor phase and alkaline earth oxides thereafter. The alkaline earth oxide particles diffuse into the iron oxide particles to form the desired M-phase structure. When the desired width and thickness of the M-phase crystal platelets is achieved, the M-phase particles are cooled by quenching. Composition of the feed solution may be modified by substituting divalent metal halides for the alkaline earth metal halide or by substituting trivalent halides or a combination of a divalent metal halide and either a penta or quatravalent metal halide for the ferric halide.
