Abstract

PURPOSE:To dispense with a receiving jig and to perform pressure bonding of a hermetically closed container by introducing the surfaces to be bonded holding an adhesive composed of a conductor or a magnetic material therebetween into a high frequency induction magnetic field to generate heat in the adhesive to melt the adhesive and heating an inner layer to expand the same and pressing the molten adhesive layer from both surfaces thereof. CONSTITUTION:The upper and lower parts 2, 3 of a pressure container are formed into a container shape by finally bonding and fixing the surfaces 4, 5 to be bonded thereof each other. At first, an adhesive 6 is held between the surfaces 4, 5 to be bonded and a fixing jig 8 having heating coils 7 built therein is set to the outer wall surfaces of the surfaces 4, 5 to be bonded and a high frequency current is allowed to flow to the coils 7 and, thereafter, the molten adhesive is cooled. When the adhesive 6 held between the surfaces 4, 5 to be bonded is a conductor, a usual one such as a wire or a copper wire is used. When a sheet member wherein a magnetic material is dispersed in a synthetic resin is bonded to an adhesive surface over a wide range, a magnetic material is used to enhance electromagnetic induction heating effect.

器を合成樹脂により製作することを可能にする。This type of joining method using a press as a pressurizing device requires a receiving jig on the side facing the pressurizing portion, so that the shape of the object to be adhered is limited. In a closed container such as a tank, the receiving jig could not be inserted inside the container, and pressure bonding was difficult. The present invention does not require the receiving jig described above, enables pressure-bonding of a closed container, and enables production of a pressure container such as a water softener tank that has conventionally relied on a steel material from a synthetic resin.

料よりなる。SUMMARY OF THE INVENTION The present invention relates to a method for adhering a pressure vessel made of resin, in which a conductor or a magnetic material is attached to the adhering surface of a vessel portion formed of a synthetic resin body composed of a skin layer and an inner layer. By sandwiching the adhesive material consisting of, and putting the adhesive surface in a high frequency induction magnetic field, the adhesive material instantly generates heat,
It is characterized in that the adhesive surface is melted and the inner layer is expanded by heating, and the molten adhesive surface is pressed from both sides of the layer to be closely adhered. In this case, the synthetic resin body has a thermoplastic resin material such as polyethylene, polypropylene or ABS resin as a skin layer and a foamed resin such as polystyrene foam, azodicarboxylic acid amide or urethane foam as an inner layer, or is manufactured by a foam molding method. The formed skin is a skin layer, and the resin of the foam layer is an inner layer made of a foamed resin material.

Mating. A plurality of wire rods made of wire, copper wire or magnetic material is previously wound around the fitting surface in an area as wide as possible. Furthermore,
By arranging an auxiliary pressure device on the outer wall surface of the bonding surface and pressing the melted bonding surface from the outside of the container, the pressure applied to the bonding portion can be further increased and the bonding can be made stronger.

If kept, the skin layer is melted and the adhesive surfaces are mixed with each other, and the foaming layer of the inner layer of the container wall is gas-expanded by the heating of the adhesive material. Therefore, the expansion force of the inner layer pressurizes the adhesive surface from both sides, and the adhesion between the two becomes stronger. In this case, in order to concentrate the expansion force on the adhesive surface, the adhesive force is further increased by tightening the adhesive surface from outside the container on the adhesive surface with a suitable pressure device.

向上する。As the adhesive material 6 to be sandwiched between the adhesive surfaces 4 and 5, a commonly used material such as a wire or a copper wire can be used as it is as an electric conductor. Further, the electromagnetic induction heating effect is improved by using a magnetic material such as sticking a sheet body in which a magnetic material is dispersed in a synthetic resin over a wide range of the adhesive surface.

損による発熱The high-frequency induction heating utilizes a phenomenon in which a conductor or a magnetic substance is placed in a high-frequency magnetic field, as is known, and heat is generated in an extremely short time due to Joule heat due to hysteresis loss and eddy current.

れる。According to the above formula, the heating efficiency is proportional to the square of the coil current and the number of coil turns, and is proportional to the frequency, the effective permeability and the square root of the specific resistance. Therefore, the higher the frequency, the higher the heating efficiency, and the tendency of radio waves to concentrate on the surface of the object becomes remarkable. On the contrary, when the frequency is increased, the permeability of the high frequency is decreased, and as a result, only the surface heating is performed and the internal heating temperature becomes non-uniform. The penetration depth S of the electric current is represented by the following mathematical formula.

により強固な接着が可能である。The method for adhering the resin pressure vessel of the present invention uses the wide range of thermoplastic resin materials and foamed resin materials as described above, and makes the adhering surface easily and firmly by the known high frequency induction heating method. Can be glued. Further, in that case, since it is not necessary to previously arrange a tool such as a receiving jig inside the bonding surface, it is possible to bond and mold any complicated shape including a hollow container such as a tank.
Therefore, it becomes possible to manufacture a large resin pressure tank, which has been impossible in the past, at low cost without using a pressurizing device, and it is expected that the application of the synthetic resin material to an outdoor tank or the like will be expanded. In this case, since the bonding area is not limited, the strength of the joint can be made equal to that of the base material, and it becomes possible to manufacture a pressure vessel that requires a high degree of airtightness. Furthermore,
If high frequency induction heating and mechanical pressure method are used in common, strong adhesion can be achieved in a short time.
