摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently producing a molded article which has excellent shock absorbing characteristics and is scarcely deformed, even when a heavy article to be used as an article to be shock-absorbed is loaded on the molded article. SOLUTION: This method for producing the molded article, characterized by supplying a slurry comprising a composition having a Canada standard freeness(CSF) of >=550 ml into a mold having many small holes in the walls, removing water used as the medium of the slurry from the small holes, depositing small-impermeable fine components in the slurry on the inside of the mold to form the wet molded article, pressing the wet molded article in the mold to enhance the density of the maximum compressed place to >=1.1 times that of the non-compressed wet molded article, and then allowing heated air to flow in the deposition layer of the molded article to dry the molded article.

摘要： PROBLEM TO BE SOLVED: To produce a surface-coated natural fiber molding excellent in recyclability by making a water-soluble film plasticized by water adhere to the surface of the molding containing natural fibers mainly while the film is stretched. SOLUTION: An upper part film 24 plasticized by water and heat is arranged above a molding 10 containing natural fibers as a main component. While the film 24 is made to approach the molding 10, air is sucked from the bottom surface of the molding 10 by using a suction means to suck the film to the molding 10, the film 24 is made to adhere to the upper surface of the molding 10 while being stretched on an uneven surface contacting an object to be cushioned, and the upper surface is coated with the film 24. Next, an lower part film is placed under the molding 10 the upper surface of which is coated with the film 24, the film 24 of the peripheral part of the molding 10 and the lower part film are laid to overlap each other and adhered to each other by being added with heat and water, and protruded films are cut off to obtain a coated low density molding easy of recycling.

摘要： PROBLEM TO BE SOLVED: To provide a heat and cold insulating box which has performance suitable for transportation or storage of an article which is required to be controlled at an optimum temperature, is simple to manufacture and is easy to separate a base material when recycling.
SOLUTION: A thick low density molded body and a paper base are combined to provide a box having heat and cold insulating properties. That is, the low density molded body which is obtained by depositing fine components is put as a core in a gap between an inner wall and an outer wall of a paper box having a double wall comprising the outer and inner walls to form the heat and cold insulating box.

摘要： PROBLEM TO BE SOLVED: To obtain a lightweight low-density molded article having excellent cushioning properties by a wet molding method. SOLUTION: This low-density molded form with thick-walled ribs is obtained by the following process: a mold with a number of perforations on the wall surface is fed with a slurry having a Canadian standard freeness of >=550 mL to remove water as the slurry medium through the perforations to accumulate a perforation-impassable fine component in the slurry in the mold, thus forming a wet molded product, which is then dried.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing, in a wet process using slurry, a molded product having a complicated shape with both concavity and convexity which has not been able to be molded with a conventional concave-type molding mold. SOLUTION: This method is to use a molding mold capable of being divided into a plurality of parts as a concave-type molding mold. The concave-type molding mold has many pores perforated in the wall surface and one side of the mold is open. A slurry composition has preferably a Canadian standard freeness(CSF) of >=550 mL.

摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive and environment-friendly box by applying water-resistant treatment on a box or a box member comprising a low density substance with a specific density or less which is obtained by dehydrating slurry including a composition with Canada standard freeness of a specific value or higher mainly comprising a cellulose fiber by using a mesh and then drying. SOLUTION: Slurry comprising a composition with Canada standard freeness of 550 ml or more mainly consisting of a cellulose fiber is dehydrated by using a mesh and then dried, and a box or a box member made of the resulted low density substance with a density of 0.25 g/cm3 or less is subjected to water- resistant treatment. Among other things, a substance which is obtained by processing under compression conditions that a thickness of the dried low density substance may be 50% or more of the thickness of a wetted low density substance obtained by dehydrating the slurry without pressure applied is preferable. Thus a water-resistant box or box member which is environment-friendly, inexpensive and excellent in heat and cold insulation can be obtained.
