Processes for forming a filter material that includes coating a filter particle with a coating comprising a lignosulfonate, carbonizing the coating, and activating the coating. The filter particles may include a variety of filter particles, including but not limited to fibers, granules, and screens, and be formed from a variety of materials, such as metals, metal alloys, carbon, ceramic, or glass. Also, the lignosulfonate-coated filter particles may include a large amount of mesopore and/or macropore volume when carbonized and activated. One exemplary process for forming a filter material includes diluting ammonium lignosulfonate with water, mixing the solution with milled glass fibers, removing the excess lignosulfonate solution from the fibers, drying the lignosulfonate coated glass fibers at 65&#xb0; C. for 12 h, carbonizing the coated glass fibers in a furnace ramped to 70&#xb0; C. with a rate of 7&#xb0; C./min for 30 min in a flowing nitrogen atmosphere, and activating the carbonized coated glass fibers in a furnace at 750&#xb0; C. for 6 h in a flowing nitrogen/steam atmosphere.

Processes for manufacturing particles coated with activated lignosulfonate

Filters and filter materials for removing microorganisms from a fluid are provided along with processes for using the same. The filters include a housing having an inlet and an outlet and a filter material disposed within the housing, wherein the filter material is formed at least in part from a plurality of filter particles having an activated coating with a lignosulfonate.

Filters and filter materials for the removal of microorganisms and processes for using the same

Processes for forming a filter material are provided. The processes include the steps of coating a filter particle with a lignosulfonate, carbonizing the coating, and activating the coating.

A composition of polyolefin, ester additive, and hyperbranched polymer with improved tensile energy-to-break value compared to polyolefins wihtout the hyperbranched polymer. The concentration of the hyperbranched polymers can be between about 0.1% and about 10% by weight of the polyolefins. The polyolefins have a melt flow index of about 14 g/10 min or greater.

Compositions of polyolefins and hyperbranched polymers with improved tensile properties

The bleeding of lignosulfonates from lignosulfonate-treated substrates when contacted under humid conditions is reduced by rendering the lignosulfonates water-insoluble via reacting them with an amine polymer-epichlorohydrin adduct containing at least one quaternary ammonium group under acidic conditions.

Methods for the reduction of bleeding of lignosulfonates from lignosulfonate-treated substrates

The strength of lignocellulosic materials is improved by treating them with water-soluble strengthening agents containing sulfonic units, and rendering these agents water-insoluble by reacting them with compounds containing epoxide rings and quaternary ammonium groups. Thus, a substantial reduction or elimination of the bleeding of said strengthening agents from the lignocellulosic materials when touched with wet hands or contacted under humid conditions is achieved.

Strengthening compositions and treatments for lignocellulosic materials

The present invention relates to partially impregnated lignocellulosic materials. When impregnated with strengthening agents, the partially impregnated materials exhibit increased overall strength while maintaining sufficient adhesive bondability of the surface opposite the impregnation surface.

Partially impregnated lignocellulosic materials

The strength of lignocellulosic materials is improved by treating them with water-soluble strengthening agents containing sulfonic units, and rendering these agents water-insoluble by reacting them with compounds containing azetidinium rings. Thus, a substantial reduction or elimination of the bleeding of said strengthening agents from the lignocellulosic materials when touched with wet hands or contacted under humid conditions is achieved.
