COMPOSITIONS AND METHODS FOR PROVIDING INCREASED STRENGTH IN CEILING, FLOORING, AND BUILDING PRODUCTS
20170284026 · 2017-10-05 ·

The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.

A method of plugging a honeycomb body includes mixing a plugging mixture at a mixing temperature, wherein the plugging mixture comprises a plurality of inorganic particles, inorganic binder, organic binder, and water; dispensing the plugging mixture into a patty mold at a dispensing temperature; cooling the plugging mixture within the patty mold to a cooled temperature, such that a cement patty is formed; and pressing the cement patty into a plurality of channels in a honeycomb body, wherein the mixing temperature and the dispensing temperature are above a hydration point temperature of the organic binder in the plugging mixture, and the cooled temperature is below the hydration point temperature of the organic binder in the plugging mixture.

Adhesive for moss

An adhesive for moss and a method for preparing the adhesive are provided, wherein the method includes steps of: adding melamine, urea, attapulgite and sepiolite powder into a ball milling tank, and adding milling balls into the ball milling tank for ball milling; then collecting ball-milled materials; adding konjac glucomannan, chitosan and collagen into water and stirring, wherein during stirring, half of the ball-milled materials are added into the water; then adding latex powder, stearic acid and ammonium zirconium carbonate, and stirring, wherein during stirring, the other half of the ball-milled materials are added into the water. The adhesive for moss can be used for bonding moss with sufficient bonding effect, which is environment-friendly and will not harm the moss; meanwhile, the konjac glucomannan, the chitosan, the collagen attapulgite and the sepiolite powder which are contained in the adhesive can provide nutrition for the moss.

Asphalt cement concrete interlayer system for reflective crack relief

An asphalt-cement concrete (“ACC”) interlayer formed of a plant-mix material reinforced with aramid fibers, deposited at a thickness of at least one inch (1″) over a Portland-cement concrete (“PCC”) or ACC base, can extend the service life of a hot-mix asphalt (“HMA”) surface layer installed over the interlayer by retarding or preventing “reflected” cracks—cracks in the surface layer that correspond to cracks, damage and irregularities in the PCC or ACC base. When the surface layer's useable life has expired, it can be removed and replaced, and the interlayer can continue to protect the new surface layer.
