    Synthetic Inorganic Fine Particles, Retention Aids and Water Treatment Systems and Methods of Using the Particles
    Conventional papermaking systems feed water-based slurries, the so-called " papermaking ", which includes wood fibers, microparticles, and other elements to the working web of a paper machine to facilitate the formation of paper matrices, Drying and pressing to produce the final sheet product. What is needed in such a process is to efficiently drain excess water without unnecessary removal of the required fibers, microparticles and other solid materials to form a heterogeneous matrix. Unnecessary water retained imposes a burden on the downstream process, for example the drying process. However, the removal of the desired solids adversely affects the quality of the final paper sheet. Also, drainage can adversely affect sheet formation.
    Retention assist systems have been developed to improve the formation of paper sheets and to increase the retention of fibers, microparticles and other solid materials needed for better drainage of the paper matrix in the paper sheet forming section of a paper machine. Such a system has the advantage, in part, to make the paper machine operate cleaner while producing better sheets at faster machine speeds. Among the maintenance assistance systems are natural and synthetic fine particle systems. Some of these delay-assisting systems are based on colloidal aluminum hydroxide, colloidal magnesium silicate, bentonite, colloidal silica, and organic polymers.
    Depending on cost, quality, consumer requirements and other conditions, the paper manufacturer may adopt a number of different methods of using the sustaining agent. One way is to add a coagulant to the thin stock precursor. Such agents act to aggregate or aggregate fibers, microparticles, and solids. Typical formulations are point mills and / or polymers. However, such a system imparts a shear force to the solids in the filtration device, resulting in smaller aggregates than intended for better sheet formation. The retention aid helps maintain the fibers, microparticles, and other desirable solids that can be added to the system prior to passing through the head box of the paper machine to begin forming the paper matrix on the paper machine web. These retention aids cause a second aggregation that differs from the previous aggregation.
    Such auxiliaries exhibit various effects due to various variables in the papermaking process. One approach is to blend various adjuvants with different ratios to the product. These various ratios in the adjuvant composition are intended to satisfy the requirements of the furnish for overall system performance. Such methods often result in manual and accidental rather than technical adjustments. Therefore, there is a need for better performance drainage and maintenance auxiliaries and methods of using such auxiliaries in the papermaking process.
    The flocculated particle system is also useful for water treatment by trapping or removing unwanted particles and oils or other lumps from the water. While there are many systems for water treatment based on coalescence principles, new and useful coagulants are still required.
    It is therefore an object of the present invention to provide synthetic inorganic microparticles, especially metal microparticles, that are equivalent in new or improved performance compared to conventional maintenance and drainage aids in the papermaking art.
    It is another object of the present invention to use synthetic inorganic microparticles in a novel manufacturing process in paper systems by using such particles as drainage and maintenance aids. International Patent Publication No. WO 92/20862 discloses a process for improving the production of papermaking products and paper by adding a cationic polymer and a porous metal silicate separately to a papermaking system and mixing thoroughly. The order of addition of these components is not critical, but a preferred additional order is that the polymer is added before the final high shear point. The porous metal silicate is then added and the resulting mixture is fed into the headbox of the drafting machine without further shearing. The product produced by the process of the present invention is useful for directing oil and water, and for forming paper from pulp slurry.
    US Pat. No. 3,784,442 reports the reaction of aluminum sulphite under sodium silicate in an aqueous medium. The resulting precipitate is filtered, washed and dried. The products prepared by this invention are useful as pigments and moisture regulators, especially as paper fillers and rubber reinforcing materials.
    U.S. Patent No. 4,213,874 discloses a microporous, precipitated alkali metal aluminosilicate having increased ion exchange properties. The products of this invention are useful as softening and detergent additives with the same base or ion exchange capacity as known zeolite base exchange or absorbents.

    The present invention also relates to a method of using synthetic inorganic microparticles in a water treatment system and a method of using such synthetic inorganic microparticles in a retention assisting system and a papermaking system.

For example, the metal salt may be a silicate, a phosphite, and / or a borate component or a reaction product thereof and the components selected therefrom are reacted to form a reaction product of step (1) Can be added simultaneously to the furnish and / or the polymer. Metal salts, silicates, phosphates, and / or borate components; Reaction products; Paper-thinning; And the addition of the polymer can be done in several orders in one of several parts of the papermaking machine or in a process line entering the papermaking machine to produce denatured paper papers. For example, the papermaking furnish or polymer may be premixed with the reaction product before the others are added. The present invention may include any step of recirculating the product of the paper machine to the process. Such recycled materials can be one source of the various components of the component. As an example of modifying the order of these steps or portions thereof, in one example, the papermaking furnish of step (2) and the polymer may be premixed before the reaction product of step (1) is added. In another example, the polymer may be added after the reaction product of step (1) has been premixed with the papermaking furnish of step (2). In another example, the reaction product, the paper furnish, and the polymer are mixed at the same time. Various other mixing and addition times can be used to produce the modified paper finishing of step (2).

Preferably, the polymer is a synthetic organic polymer, such as a multi-site electrolyte (anionic, cationic or amphoteric) or non-ionic polymer and has at least one structural repeating unit. For example, homopolymers, copolymers or terpolymers are not necessarily limited to these three forms. Since deformation may occur in the polymer, distribution of the polymer molecules may appear in the polymer. The polymer may be supplied in various forms, for example in the form of powders, granules, aqueous solutions, gels, and emulsions. Among the non-ionic polymers, preferred are poly (acrylamide) and poly (ethylene oxide). Among the anionic polymers, preferred are carboxyl group-containing polymers and sulfonic acid group-containing polymers.

    (4) efficiently removing the aggregate by filtering the water containing the aggregate.
    The formed agglomerates undergo water treatment by collecting unnecessary substances such as electrostatic bonds or physically solid or oil suspensions. The steps may be performed sequentially or concurrently by combining sequences. For example, the process water flowing out of the papermaking mill can be treated immediately before being discharged to remove suspended fibers or other solids. The added component forms an aggregate, collects the suspended fiber or solid and performs purification operation. Although this example deals with process water flowing out of a papermaking mill, the present invention can be applied to water entering the mill to remove solids present in nature and to any water requiring purification.
