Abstract:
A centrifugally rolling granulating and coating device (1), comprising a fixed wall (7) of which horizontal section part (7a) in contact with powder and granular material (2) is formed in circular shape and a rotating disk (5) which is installed inside the fixed wall (7) at a distance (12) and rotated horizontally by a motor (13), wherein an air feeding device (21) to feed dry air (22) to the upper surface of the rotating disk (5) is installed on the rotating disk (5), the air feeding device (21) comprises a cylindrical straight pipe part (25) and a conical air inlet port (23) and installed movably vertically in a centrifugal flow chamber (6) and, during a granulating process, the air feeding device (21) stops feeding the dry air (23), waits at an upper position (H), lowers to a lower position (L) after the granulating treating has been completed, and feeds the dry air (22) onto the rotating disk (5) to dry the granule, whereby spherical particles small in grain size, small in grain size distribution width, and high in sphericity can be produced efficiently in a single device.
Abstract:
The invention covers an antiwetting composition for imparting hydrophobic properties onto fabrics and fibrous substrates, as well as a method for producing a hydrophobic article. The composition of the present invention includes a dispersion of polymeric fluoroaliphatic ester and a silicone resin prepolymer in a water-based carrier. The polymeric fluoroaliphatic ester is included in the dispersion at about 0.12 to 0.5 percent solids by weight. The silicone resin prepolymer is generally a polysiloxane having silanol terminal groups. The silicone compound is added to the dispersion in a range of about 0.08 to about 0.34 percent solids by weight. The components are impregnated in a fiber substrate and subsequently cured to provide an article having improved hydrophobic properties over known antiwetting compositions.
Abstract:
The invention relates to building trade compliant thermal, phonic and/or hygric insulating material containing at least one insulating layer consisting of anorganic or organic insulants. At least one side of the insulating material is endowed with a functional waterproof layer, permeable to steam vapour. The functional layer is connected to the insulating material on at least one of its sides. The invention also relates to a method for the manufacture of the above-mentioned insulating material and a method enabling the avoidance of dust from mineral-fibre insulation material.
Abstract:
A porous membrane produced by preparing a slurry made from at least one micropyretic substance and at least one liquid carrier. The slurry is dried into a green form having a desired geometric configuration. Combustion of the green form produces the porous membrane.
Abstract:
TiN sintered bodies and coatings are produced by dispersing nanocrystalline TiN powder in water and/or a polar organic solvent as the dispersing agent in the presence of at least one low-molecular organic compound having at least one functional group which can react and/or interact with groups on the surface of the powder particles, removing the dispersing agent and sintering the surface-modified TiN which has been processed into green bodies or coatings before or after the removal of the dispersing agent.
Abstract:
A body of carbonaceous or other material for use in corrosive environments such as oxidizing media or gaseous or liquid corrosive agents at elevated temperatures, in particular in molten salts such as cryolite, is coated with a protective surface coating which improves the resistance of the body to oxidation or corrosion and which may also enhance the bodies electrical conductivity and/or its electrochemical activity. The protective coating is applied in one or more layers from a colloidal slurry containing reactant or non-reactant substances, or a mixture of reactant and non-reactant substances, in particular mixtures containing silicon carbide and molybdenum silicide or silicon carbide and silicon nitride, which when the body is heated to a sufficient elevated temperature reaction sinter as a result of micropyretic reaction and/or sinter without reaction to form the protective coating.
Abstract:
A method of treating a surface with a sprayed composition including bitumen to form a membrane and which comprises providing a raw material supply of bitumen which is heated to 140°C, and an alkaline supply of blending water which are heated and then blended to form a blended mixture/emulsion, and then pumped when required through a first delivery line to a first discharge head, and a further supply of water which is treated to be acidic is pumped along a second delivery line to a second discharge head, in which the first and second discharge heads are positioned close to each other and arranged to direct respective streams of the blended mixture and the acidic water to impinge one upon the other downstream of the delivery heads to form a dispersed spray which is then applied to the surface to be treated, and which then cures rapidly to form a membrane on the surface. The method of the invention and the components of the spray composition enable bituminous coatings to be applied without need for high temperature application as used in existing hot coating application of asphalt bitumen.
Abstract:
A method of manufacturing a composite material in which a fibre matt is placed adjacent a plate electrode in ceramic sol. The application of an electric field to the sol via the electrode results in the deposition of sol particles on the electrode which subsequently permeate the fibre matt. The permeated fibre matt is then removed from the sol, dried out and heated to sinter the sol particles.
Abstract:
A method of forming a bituminous membrane for application to a surface in order to render the surface resistant to penetration by water which comprises: providing a raw material supply of bitumen e.g. a blend of 50/200 PEN bitumen, and an aqueous blending supply of water in a pH range which is slightly alkaline; heating the bitumen and the aqueous blending supply and blending them toghether in a blending unit to form a blended mixture/emulsion; and storing the blended mixture/emulsion in a flowable form prior to supply to a spray coating device in which a separate acidic aqueous dispersing supply is also fed to the spray coating device so that two streams of the blended mixture/emulsion and the acidic dispersing supply impinge on each other to form a dispersed spray applicable to the surface to be treated.
