摘要： Processes disclosed are capable of converting biomass into high-crystallinity, hydrophobic cellulose. In some variations, the process includes fractionating biomass with an acid (such as sulfur dioxide), a solvent (such as ethanol), and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; and depositing lignin onto cellulose fibers to produce lignin-coated cellulose materials (such as dissolving pulp). The crystallinity of the cellulose material may be 80% or higher, translating into good reinforcing properties for composites. Optionally, sugars derived from amorphous cellulose and hemicellulose may be separately fermented, such as to monomers for various polymers. These polymers may be combined with the hydrophobic cellulose to form completely renewable composites.

摘要： What is disclosed is a cellulose-based product and a method for producing the aggregate admix product that includes the steps of thoroughly hydrating cellulose fibers, mixing clay and mineral particulates with a liquid to produce an emulsion, adding the emulsion to the hydrated cellulose fibers, and thoroughly impregnating the cellulose fibers with components from the emulsion and producing an aggregate admix product. The aggregate admix product is combined with cement and a liquid to create a cementitious product that can be directly sprayed onto building structures.

摘要： A method for preparing a silane coupling agent/silica/plant fiber composite includes the following steps: S1: pretreating plant fiber; S2: preparing hydrolysate of a silane coupling agent; S3: preparing a silane coupling agent/plant fiber composite; S4: preparing a silica nanoparticle dispersion; and S5: preparing a silane coupling agent/silica nanoparticle/plant fiber composite. Through the covalent interaction among a silanol group (Si—OH) formed by hydrolysis of the silane coupling agent, Si—OH of the silica, and a hydroxyl group (—OH) on the surface of the plant fiber, the present invention enables silica nanoparticles to be grafted on the surface of the plant fiber. Using a hydrophobic film formed by the silane coupling agent, harmful ions are prevented from invading, and the volume stability of the fiber is improved. Using the pozzolanic activity of the silica nanoparticles, the alkalinity and calcium hydroxide content around the fiber are reduced.

摘要： A method for preparing a low-air entraining, low viscosity lignosulfonate composition. The method comprises: a) applying heat to the crude lignosulfonate composition under suitable conditions to reduce sugar levels to below 10%, optionally below 5%, optionally below 3%), or optionally below 1%, on a dry basis; b) mixing a crude lignosulfonate composition with an effective amount of a source of trivalent ion to complex air entraining fatty acids and resin acids; c) lowering temperature to prevent viscosity buildup.
