Abstract: 1,063,244. Porous coated sheet material; fluid filtering medium. LLOYD & HILLMAN Ltd. Aug. 6, 1963 [Aug. 6, 1962], No. 30990/63. Headings B1D, BIT and B2E. A medium capable of removing ultrafine particles from fluids comprises a porous base e.g. of paper, and a micro-porous layer adherent thereto. This layer comprises fibres of which a significant proportion extend outwards from the base at an angle of at least 30 degrees and has a maximum pore diameter of 10 microns and a voids volume of at least 75%. It may be made by applying to the base a dispersion comprising a dispersing fluid and particulate fibrous material and controlling the type, size and number of fibres and the state of their dispersion to obtain the required properties when the fibrous material is deposited on the base. Successive layers may be applied in this way. The first applied layer may be a binding layer containing a binder, or the or each main coating layer may contain a binder, e.g. an epoxy resin phenol-, urea-, melamineformaldehyde resins, polyester resins, polyethylene, polypropylene, polyoxymethylene, polyisobutylene, polyamides, cellulose acetate, ethylcellulose, vinyl chloride copolymerised with vinyl acetate, polyvinyl chloride, polyvinylidene chloride, polyvinyl butyral, p.t.F.e., polytrifluorochloroethylene, ligrin-sulphonate resins, starch, casein, terpene resins, polyacrylic resins, alkyd resins, synthetic rubbers such as butadiene-styrene copolymers. The fibrous material may be potassium titanate, asbestos or glass. The dispersion may also include a non-fibrous particulate material, e.g. silica.

Abstract: A PROCESS IS PROVIDED FOR FORMING MICROPOROUS SHEET MATERIAL USEFUL AS FILTERS, WHICH IS SUBSTANTIALLY UNIFORM IN THICKNESS, POROSITY AND DENSITY, FROM A SLURRY OF PARTICULATE MATERIAL. A POROUS SHEET MATERIAL ALSO IS PROVIDED, WITH ONE OR A PLURALITY OF LAYERS, EACH COMPOSED OF A MICROPOROUS MULTISTRATUM LAYER WHICH MAY OPTIONALLY BE ADHERENT TO A POROUS SUBSTRATE AND HAVING A HIGH VOIDS VOLUME, A PORE SIZE OF LESS THAN 25U, AND SUBSTANTIALLY UNIFORM IN THICKNESS, POROSITY AND DENSITY. AN APPARATUS IS PROVIDED USEFUL FOR PREPARING SUCH MATERIAL, SUCH AS A FOURDRINIER MACHINE, INCLUDING ONE OR MORE BARRIERS SUCH AS DOCTOR BLADES POSITIONED TO CONTROL DEPOSITION OF SLURRIED PARTICULARE MATERIAL UPON A SUPPORT SO THAT THE DEPOSITION OF DEFLOCCULATED AND UNIFORMLY FLOCCULATED MATERIAL IS UNIFORM, AND LARGE NONUNIFORM FLOCS CANNOT BE DEPOSITED ON THE SUPPORT.
