摘要： A method for producing alkali metal polysilicate complexes and their use as builders in detergents is disclosed. The polysilicates are produced by hydrothermally reacting, under certain controlled conditions, an aqueous dispersion of finely-divided silica, an alkali metal hydroxide and a sulfate salt of an alkali metal. The synthesized reaction mixture is then spray dried and the solid product fractured, pulverized and agitated in a rotating drum to form a product having particularly advantageous properties. The products of the invention can be used in adhesives, in the production of silica gel, in textiles and the like. However, their use as builders in detergents and in combination with known anionic, nonionic and amphoteric surface active compounds (surfactants) is disclosed and claimed.

摘要： A method for controlling the viscosity of dispersed clay slurries is disclosed. In accordance with the invention the problem associated with shipping or storing clay slurries in tank cars or tanks, that is, significant increases in the viscosity of the slurry which often results in the formation of a gelled mass, is overcome by the addition of the pentasodium salt of diethylenetriamine pentacetic acid (DTPA). The addition of the diethylenetriamine pentacetic acid salt serves to control the viscosity of the clay slurry in a manner such that it remains at a substantially uniform and low level even when the slurry is shipped or stored over extended periods of time. The diethylenetriamine pentacetic acid pentasodium salt is added to the slurry in relatively small quantities, i.e., up to 5.0 pounds/ton clay and unexpectedly does not affect the properties or characteristics of the clay pigment or product.

摘要： A method for preparing a coating grade kaolin clay from a crude clay including discoloring iron contaminants in the form of iron pyrites. The clay is roasted in an oxidizing atmosphere to convert at least a portion of the sulfurous contaminants to a form exhibiting increased magnetic susceptibility and increased solubility in chemical leachants. Thereafter, the clay is formed into an aqueous slurry and subjected to a magnetic field to remove at least part of the converted components, and then subjected to conventional leaching and filtering operations.

摘要： Precipitated silica comprising porous silica particles having a cumulative surface area for all pores having diameters greater than 500 null of less than 8 m2/g, as measured by mercury intrusion, and a percentage cetylpyridinium chloride (% CPC) Compatibility of greater than about 55%. The precipitated silica product is especially well-adapted for use in dentifrices containing cetylpyridinium chloride, which do not attach to the low surface area silica product in a meaningful level and thus remain available for antimicrobial action. Processes for making the silica product are also provided.

摘要： A method of significantly improving the brightness and shade properties of a high quality PCC product. The method includes providing a calcium containing feed source that contains discoloring impurities. The calcium containing feed source is formed into an aqueous slurry of calcium carbonate. Thereafter, the slurry is fine screened through a 325 mesh screen in order to yield a slurry of filler grade calcium carbonate. The filler grade calcium carbonate slurry is wet milled in order to liberate the discoloring impurities and reduce the median particle size of the calcium carbonate to less than 2 microns. The discoloring impurities are then magnetically separated from the milled calcium carbonate slurry by subjecting the slurry to a high intensity magnetic filed. After the magnetic separation step, the purified slurry may be de-watered to yield a dry powder; or alternatively, the slurry may be retained in aqueous form. In any event, the resultant calcium carbonate product has a median particle size of less than 2 microns and a TAPPI brightness of greater than 96.

摘要： A coarse particle kaolin clay is provided having an average Stokes equivalent particle diameter of about 4.5-6.0 microns, a BET surface area of about 8-11 m.sup.2 /g, and preferably having a median Malvern particle size of about 9.0-10.5 microns as determined by laser light-scattering measurement and a high aspect ratio preferably of about 12-14 as determined by Sphericity Model calculations. The coarse particle kaolin clay provides low viscosity build, good reinforcement properties and excellent surface finish qualities as a filler in thermoset composite materials, such as polyester molding compounds, and also provides excellent pigmenting properties in paints and industrial coatings. Preparation of the coarse particle clay involves blunging and degritting a crude kaolin clay, conducting three separate centrifugation steps with the desired product stream being, in sequence, the coarse underflow clay from the primary centrifuge, the coarse underflow from the secondary centrifuge, and then the fine overflow from the tertiary centrifuge, followed by magnetic separation, screening, chemical leaching, drying and milling to produce a kaolin clay product having the above-described physical properties and performance characteristics.
