Abstract:
The present invention relates to an insulation used in home appliances and building materials. A method of manufacturing an insulation includes fabricating an adhesive solution by inputting a binder to water contained in a water tank, inputting long glass fibers to the adhesive solution, removing moisture by supplying the long glass fibers to a mesh belt, wherein the mesh belt move left and right and front and rear so that the long glass fibers are uniformly spread, fabricating glass fiber paper by drying the long glass fibers, winding the glass fiber paper in a roll form, and preparing the glass fiber paper rolls in multiple layers, stacking two or more sheets of the glass fiber paper supplied from the rolls, and sewing the sheets of stacked glass fiber paper.
Abstract:
The invention relates to a refrigeration device, in particular a domestic refrigeration device, comprising a plastic component (15), in particular a plastic blank for a delimiting wall (7) for delimiting a hollow space of the refrigeration device, which is filled with a thermally insulating foam (3). According to the invention, the plastic component (15) is manufactured from a natural-fiber reinforced plastic consisting of a plastic support material (21) and natural fibers (23) embedded therein.
Abstract:
The insulated unit (1) of the present invention comprises an inner liner (9), an outer liner (8), an insulation space (10) between the inner liner (9) and the outer liner (8), an insulating material (2) filling the inner space (10). The inner liner (9) and the outer liner (8) of the insulated unit (1) are formed by a composite sheet (11) including one or more plastic sheets (3) and one or more film materials (7) that is formed by metal and thin plastic layers.
Abstract:
The use of a vacuum heat insulation material using a core material formed by laminating inorganic fiber sheets of particular shape and composition provides a heat insulation box which is superior in time-varying heat insulation performance and in productivity. A vacuum heat insulation material which is easy to pattern; therefore, a vacuum heat insulation material which is suitable for portions requiring heat insulation can be easily prepared and applied to a heat insulation box. This property improves the covering ratio of the vacuum heat insulation material to the heat insulation box and also improves the heat insulation performance of the heat insulation box. For this reason, it is possible to improve the heat insulation property of refrigerators, heat insulation appliances, cold insulation appliances, vending machines, etc. and to improve productivity, and contributes to energy saving.
Abstract:
A vacuum insulating material which comprises a core material prepared by laminating a plurality of sheets comprising inorganic fibers which has a specific composition having SiO2 as a main component, Al2O3, CaO and MgO, and has a diameter of 10 mu m or less, a covering material having gas-barrier properties and an adsorbent; said vacuum insulating material, characterized in that it has at least one flute formed therein; said vacuum insulating material, characterized in that the core material comprises the inorganic fibers having a peak value of its fiber diameter distribution of 0.1 to 1 ñm and contains no material for binding fiber materials; and an electronic device using the above vacuum insulating material. The above vacuum insulating material can be used for producing an electric or electronic device which exhibits excellent energy-saving properties and does not give a user an unpleasant feeling.
