Abstract:
Process for the simultaneous application of at least two molten, thermoreversible organogel layers to a substrate. The organogel layers can optionally contain dispersed additive ingredients, such as pigments. The organogel layers are coated onto a suitable substrate and then rapidly cooled or chilled to form a gel. Residual solvent is then removed. Multilayer coated films are thus formed with minimal interlayer mixing or interlayer diffusion of the additive ingredients.
Abstract:
Microsphere beads (2) are mixed with a surface barrier liquid or mixture of such a liquid with a solid effective to prevent agglomeration and surface bonding of the microspheres. By the control of the application of heat and balancing temperature and active mixing, removal of water (3) from the microspheres (2) is achieved. The surface barrier liquid or mixture of such a liquid with a solid in the present invention is any one of a wide diversity of materials which prevent the agglomeration of the microspheres during the process. Suitable materials include plasticizers, diluents, extenders, monomers and oligomers, and the like.
Abstract:
Cellulose fibers are entrained in a gaseous medium in a loading zone (20) of a fiber treatment conduit (24) and sized while entrained with a sizing material. In a material application zone (30), blower (26) is capable of moving a gaseous medium at a velocity and volume sufficient to entrain the fibers which have been entrained in the loading zone (20). The sizing material may comprise a nonaqueous solution of alkyl ketene dimer or other sizing material. Also, immersions of fibers in such a nonaqueous sizing solution is another approach for sizing fibers.
Abstract:
In a process for applying a multilayered coat of lacquer, a priming layer, a base lacquer layer and one or more clear lacquer coatings are applied on a metallic surface that can be autophoretically coated. An intermediate layer can be applied between the priming layer and the base lacquer layer. The priming layer is applied as a first coating layer made of a coating agent that can be autophoretically deposited and is then baked, and the other coating layers are then applied, so that the total dry layer thickness of the multilayered coat of lacquer lies between 80 and 130 mu m and the total dry layer thickness of the clear lacquer layers lies between 40 and 80 mu m.
Abstract:
A method and system for producing an animal bedding material from recycled waste paper, and including one or more chemical additives. The base material is fiberized, and the chemical additives may include: pesticides, disease immune additives (medicines), ammonia inhibitors, fire retardants, or other additives, depending on the characteristics desired of the final product. At least one of the additives is applied as a liquid. The system includes a charge conveyor (20) which moves the waste paper stock into a primary grinder (50) thus forming paper chips. The paper chips are pulled by a primary transfer blower (60) and enters a cyclone separator (70) and subsequently placed in a fiberizer surge tank (80) and ultimately a fiberizer (90). Chemical additives may be added using the moiler (120) before packaging.
Abstract:
A process for the multi-coat painting of a substrate with a first coat of a stoved dipping paint. Said process involves the application of a second coat with a dry thickness of 10 to 30 mu m of a first aqueous base coating agent containing polyurethane resin and the wet-on-wet application of a third coat with a thinner dry thickness of 7 to 15 mu m of a second aqueous base coating agent, the further application of a coat of clear lacquer without prior stoving, followed by stoving all together, where the first base coating agent has a higher polyurethane resin than the second.
Abstract:
A polymeric resin composition comprising a polymeric resin in particulate form coated with an additive agent adhered to the surfaces of the resin particles by a coating of thermoplastic adhesive binder between the particles and the agent.
Abstract:
A method of synthesizing encapsulated nanocrystals inside protective shells is disclosed. This method produces nanocrystals of metals, alloys, and compounds which are individually encapsulated by protective graphite shells which completely separate the nanocrystals from the environment. A separation method is disclosed which eliminates most all other debris except the encapsulated nanocrystals from the preparation product. An apparatus to perform the encapsulation is also disclosed. The apparatus comprises a production chamber (45) and a collection chamber (50). An arc is created between a cathode (35) and an anode (40) formed of the material to be encapsulated. The arc generates a vapor of the anode which is quenched by an inert gas-forming graphite encapsulated nanoparticles which are collected in the collection chamber (50).
Abstract:
A method and apparatus for reacting sodium vapor with gaseous chlorides in a flame to produce nanoscale particles of un-oxidized metals, composites and ceramics. The flame is operated under conditions which lead to condensation of a NaCl by-product onto the particles. The condensate encapsulates the particles and aids in controlling desired particle size and preventing undesirable agglomeration among the particles during synthesis. Following synthesis, oxidation of the particles is inhibited by the encapsulation, and handling character of the products is greatly enhanced. Electron microscopy has revealed that synthesized products are composed of discrete nanoparticles in a NaCl matrix. The NaCl encapsulate has been effectively removed from the particles by both washing and known sublimation technique at 800 DEG C under low pressure.
