The method for the production of curved furniture components comprises:
an overlapping step of a first panel of wooden, plastic or metal material, of at least one intermediate separating layer and of a second panel of wooden, plastic or metal material for obtaining a flat semi-finished product having a perimeter edge; an interposition step of a polyurethane type adhesive between the intermediate layer and the first panel and second panel by hot dispensing of said adhesive on the surfaces of the first and the second panels which are adapted to be associated with the intermediate layer or by hot dispensing of the adhesive on the surfaces of the intermediate layer which are adapted to be associated with said first panel and second panel; a cold shaping step of the semi-finished product for obtaining a curved component; and a spraying step of a water-based auxiliary substance between the intermediate layer and at least one of the first panel and the second panel, subsequent to the interposition of the adhesive.

The present invention discloses a method for laminating a gas permeable layer onto a preformed substrate by forming a laminate precursor comprising a substrate and a gas permeable layer in which a layer of adhesive is positioned between the gas permeable layer and the substrate surface. A layer of water is formed on the surface of the gas permeable layer and the wetted surface is contacted by a preheated platen and super heated steam is ejected onto the gas permeable layer causing the adhesive to cure and bond the gas permeable layer to the substrate.

A process of making a liquid absorbing laminated structure comprising long lengths of absorptive tissues and an intermediate layer of absorptive particles is performed while the tissues are traveling in the direction of their lengths. A film of moistening liquid is transferred to a surface of a first tissue which is then supported in substantially horizontal position and showered with dry absorbent particles, which are rendered adhesive by absorption of the moistening liquid. A second tissue is superposed and the assembly is bonded together by passing it through the nip between a heated roller having a surface temperature of at least 110.degree. C. and a pressure roller. These rollers are pressed together at the nip by a pressure of at least 350 pounds per square inch and each has a surface hardness in excess of 90 Shore A Durometer.
摘要:
A method of preparing an aerogel composite, which includes a wetting pretreatment step for suppressing the generation of air bubbles in a fibrous material such as a mat, and a step of impregnating the fibrous material with a precursor by injecting the precursor in a vessel under a reduced pressure. The method provides a high quality, high insulation aerogel-impregnated composite without air bubbles.

A method for producing a semi-finished honeycomb-core product for producing a sandwich component, a method for producing a sandwich component, a semi-finished honeycomb-core product, a sandwich component, and the use thereof as a component of a motor vehicle.
摘要:
A composite system for the reinforcement of physical structures includes a plurality of unidirectional fibers arranged with respective longitudinal axes generally parallel to each other over a substantial portion of a length of each unidirectional fiber. The plurality of unidirectional fibers are non-mechanically connected. A resinous material adheres the plurality of unidirectional fibers to each other such that each one of the plurality of unidirectional fiber is adhered to at least one adjacent one of the plurality of unidirectional fibers along a substantial portion of the length of the adjacent one of the plurality unidirectional fibers.

A method of preparing a window module includes providing a metal frame having a first major surface, applying a structural glazing tape to the first major surface of the metal frame, and positioning a glass panel overtop the structural glazing tape. The structural glazing tape includes a polymer foam tape having first and second major surfaces, an adhesive layer overlying the first major surface for bonding the structural glazing tape to the structural frame, and a release layer overlying the second major surface. The method further includes filling a channel defined by the glass panel, the metal frame, and the structural glazing tape with a curable sealant, and curing the sealant to bond the glass panel and the metal frame together.
