Method for manufacturing a bonded body of galvanized steel sheet and adherend
There is provided a technique to strongly integrate a galvanized steel sheet and a resin molded article. A hot-dip galvanized steel sheet is immersed in an aqueous solution for aluminum degreasing to form a specific roughness on the surface. The surface is covered with convex protrusions having a diameter of about 100 nm, and a chromate treatment layer appears in the surface. A resin composition comprising 70 to 97 wt % of polyphenylene sulfide and 3 to 30 wt % of a polyolefin resin is injected onto the surface. The resin composition penetrates into ultra-fine irregularities and is cured in that state, and thereby a composite in which the galvanized steel sheet and the resin molded article are strongly integrated can be obtained. The shear rupture strength of the composite is extremely high.
PLASTIC-METAL HYBRID COMPONENT AND METHOD FOR PRODUCING SAME
The invention relates to a plastic-metal hybrid component and to a corresponding method for producing a plastic-metal hybrid component. The production method has the following steps: (i) providing a fiber composite semifinished product based on polyamide, at least one part of the surface of the semifinished product being made of a polymer composition which contains the following: a) 100 wt. % of a polyamide; and b) 0.5 to 20 wt. % of one or more adhesive additives of the formula (I); (ii) providing a metal main part; (iii) optionally pretreating the surface of the metal main part in order to produce functionalities; (iv) introducing the main metal part and the fiber composite semifinished product into a pressing tool and closing the tool; and (v) bonding the fiber composite semifinished product and the metal main part by means of a compression process under the effect of pressure and temperature.
Multilayer fluidic devices and methods for their fabrication
A fluidic device including an inorganic solid support attached to an organic solid support by a bonding layer, wherein the inorganic solid support has a rigid structure and wherein the bonding layer includes a material that absorbs radiation at a wavelength that is transmitted by the inorganic solid support or the organic solid support; and a channel formed by the inorganic solid support and the organic solid support, wherein the bonding layer that attaches the inorganic solid support to the organic solid support provides a seal against liquid flow. Methods for making fluidic devices, such as this, are also provided.
Heater for cigarette-like electronic cigarette with excellent heat transfer efficiency and manufacturing method thereof
A heater for a cigarette-like electronic cigarette and a method of manufacturing the heater are provided. The heater is provided with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin.
PROCESS FOR PRODUCING A COMPOSITE COMPONENT COMPRISING AT LEAST ONE METAL LAYER AND ONE POLYMER LAYER
The invention relates to a process for producing a composite component comprising at least one metal layer and one polymer layer, the process comprising: (a) heating a metal sheet which optionally comprises a surface treatment; (b) placing a polymer film on the metal sheet and optionally heating the polymer film; (c) applying a vacuum to contact the polymer film with the entire surface of the metal sheet and to remove air enclosed between the metal sheet and the polymer film; (d) optionally holding the temperature of the metal sheet and the polymer film above a temperature at which the connection of the polymer film and the metal sheet is promoted to achieve the composite component.
