The present invention relates to a method for the preparation of a solid foam, wherein the method comprises depositing discrete units of a foam on a surface to obtain a first foam deposition, followed by depositing a wet foam between the discrete units to obtain a subsequent foam deposition, and drying the wet foam. The invention further relates to a solid foam comprising discrete units of foam embedded in a foam matrix.

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.

The invention relates to a process and an apparatus for producing a molded fiber article. The process comprises the steps of dissolving fibrous materials in water to form a fibrous material suspension in a pulper, removing moisture from the fibrous material suspension by pressing to form a molded fiber article in a mold and/or drying the molded fiber article by supplying heat, demolding the molded fiber article from the mold. The process is characterized by the feature whereby, in mold drying of the molded fiber article in the mold, a moisture content of the molded fiber article of not more than 10% by weight or not more than 7.5% by weight or not more than 5% by weight is achieved.

The present invention is directed to methods and systems for manufacturing molded fiber products using a pulp slurry and apparatus submerged in pulp slurry. The system utilizes a vacuum and mesh shaping of the product to pull fiber from the pulp slurry to the mesh shape while sucking the water through the mesh shape. The molded fiber product is then pressed to bolster the strength and structure of the product. The product is then coated using centripetal force to uniformly spread the coating across the selected area of the product. After coating, the product is pressed again to ensure the waterproof and airproof structure of the product. The materials used in manufacturing the molded fiber product are biodegradable, and the apparatus to form the molded fiber product is shaped according to the desired shape and size of the product.
