    摘要： Mineral paper is provided which comprises a wet-laid sheet of 1) fibers, 2) a floc of a silicate selected from the group consisting of mica and vermiculite, the said floc having a cationic polymeric flocculant having a molecular weight in the range of from about 10,000 to about 1,000,000, and 3) a non-ionic polymeric flocculant having a molecular weight of from about 2,000,000 to about 10,000,000. A process is described herein for the preparation of the paper using the two flocculants by first flocculating with the cationic polymeric flocculant and then flocculating in another step with the non-ionic polymeric flocculant to obtain an easily drained flocculated mixture which is dewatered to obtain the mineral paper.

    摘要： A process for producing solid vermiculite products which are stable in water which comprises incorporating a source of ammonia or ammonium ions or a basic substance, preferably urea, in an aqueous suspension of vermiculite lamellae, shaping the suspension and removing water from the suspension by heating the shaped suspension at a temperature above 100.degree. C., preferably above 150.degree. C., such that ammonia or a basic substance is liberated within the suspension. The invention includes an aqueous suspension of vermiculite lamellae containing a source of ammonia or ammonium ions or a basic substance and a dry-powder mixture of vermiculite lamellae and a source of ammonia or ammonium ions or a basic substance.

    摘要： The present invention is related to the production of crystal-containing gels and papers, films, fibers, boards, and coatings made therefrom. The process for making the gels comprises three general steps: first, a fully or predominantly crystalline body is formed containing crystals consisting essentially of a lithium and/or sodium water-swelling mica selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite, and fluorphlogopite; second, that body is contacted with a polar liquid, desirably water, to cause swelling and disintegration of the body accompanied with the formation of a gel; and, third, the solid:liquid ratio of the gel is adjusted to a desired value depending upon the application therefor. Where papers, films, fibers, boards, or coatings are desired, such are prepared from the gel, and, to impart good chemical durability thereto, are thereafter contacted with a source of large cations to effect an ion exchange reaction between the large cations and the Li.sup.+ and/or Na.sup.+ ions from the interlayer of the crystals, and the products then dried. Glass-ceramic bodies are the preferred starting materials.

    摘要： A novel electrically insulating mica paper containing cellulose, but no binding agent and having a tensile strength and a porosity higher than those of pure mica paper is disclosed. The tensile strength is sufficiently high for the mica paper to be processed without backing. The novel mica paper contains mica pulp consisting of platelets of natural mica and 10 to 50% by weight, preferably 20 to 30% by weight, of cellulose fibres which preferably have a freeness of 20 to 60 on the Schopper-Riegler scale. It can be produced by adding cellulose fibres to mica pulp produced without using chemicals other than water and processing the mixed pulp by conventional methods to a paper, without using a binding agent, temperatures higher than 100.degree. C. or pressure.

    摘要： THE APPARATUS COMPRISES A ROTARY CYLINDRICAL NET DISPOSED IN A FLUID VAT AND A CONVEYOR, LOCATED CLOSE TO SAID ROTARY NET, WHICH PICKS UP LAMINATED MICA FROM THE ROTARY NET AND CONVEYS THE SAME. LOCATED IN SAID VAT ARE TWO INTERCONNECTING SECTIONS (3A,3B) WITH A NARROW ARCUATE PASSAGEWAY BETWEEN SAID SECTIONS BELOW SAID NET. THE WATER PRESSURE OUTSIDE THE CYLINDRICAL NET IS MADE HIGHER THAN THAT INSIDE THE NET AT ALL TIMES SO THAT WATER IN THE TANK MAY FLOW INTO AND THROUGH THE CYLINDRICAL NET. THE WATER IN THE FLUID VAT IS FORCED INTO HIGH SPEED TURBULENT FLOW IN SECTION (3B) WHERBY THE FLAKE MICA DISPERSED IN THE WATER MOVES A RANDOM AND STRIKES AND CLINGS TO THE NET.
