Pulp molding machine and paper-shaped article made thereby

A pulp molding machine and a paper-shaped article made thereby are provided. The pulp molding machine comprises a machine frame body, a pulp-dredging stage, a compression thermo-forming stage and an edge-cutting stage disposed on the machine frame body. The pulp-dredging stage comprises a paper slurry tank, a first upper mold and a first lower mold, a wet pulp is dredged up by the first lower mold from the paper slurry tank, and is pre-compressed by and between the first upper mold and the first lower mold to form a first semi-finished product. The compression thermo-forming stage comprises a second upper mold and a second lower mold, the first semi-finished product is thermo-compressed by and between the second upper mold and the second lower mold to form a second semi-finished product. The edge-cutting stage is utilized for cutting superfluous edges of the second semi-finished product to form a paper-shaped article.

BINDER COMPOSITION AND METHOD COMPRISING MICROFIBRILLATED CELLULOSE AND RECYCLED CELLULOSIC MATERIALS

Methods of manufacturing a sheet or a board comprising recycled cellulose-containing materials, a binder composition comprising microfibrillated cellulose and one or more inorganic particulate material, and optionally one or more additive, wherein the sheet or board has an increased modulus of elasticity and modulus of rupture compared to a board prepared in a comparable method without microfibrillated cellulose, and to board, panel and construction products manufactured therefrom.

Method and apparatus for producing large uniform thickness nanomaterial sheets

A batch-automated microfiltration press for producing large uniform thickness nanomaterial sheets includes a filtration envelope of variable size that is defined between an upper platen having a fixed position and a lower platen disposed in spaced apart, parallel relation to the upper platen. The upper platen has a plurality of input nozzles and a plurality of flow dispersers associated with each of the input nozzles. Nanoparticles are deposited onto a fine filter membrane positioned in the filtration envelope. Flow channels and drain holes are formed in the lower platen. Each of the flow channels has a non-linear path of travel. A closed-loop fluid control system maintains a predetermined rate of nanoparticle deposition onto the fine filter membrane. A motion control system controls the raising and the lowering of the lower platen, maintaining a constant displacement instead of constant pressure, enabling the production of clean, undamaged sheets of nanomaterial papers.

Method for manufacturing right-angled pulp product

A method for manufacturing a right-angled pulp product uses a mixture of cellulose fibers as pulp. Steps in the method include taking the pulp to form a flat shape, pressing and heat-drying the flat-shaped pulp to form a pulp product having a plurality of troughs, taking out the pulp product, cutting off a burr around the pulp product, applying adhesive onto each of the troughs, and bending two adjacent plates at two sides of each trough to form a right angle and a fixed shape.
