Description

  The present invention relates to a surface modification treatment apparatus.

  The surface of a solid substance made of a polymer such as silicon rubber or polyethylene resin, metal, ceramic, or the like may be difficult to be subjected to surface treatment such as adhesion of another member, coating of a paint, or printing. Therefore, conventionally, a surface modification treatment apparatus has been studied that modifies the surface of a solid substance to facilitate surface treatment such as adhesion, painting, and printing.

  As such a surface modification treatment apparatus, the reforming compound is vaporized, and a mixed gas formed by mixing with a flammable gas such as air or an auxiliary combustion gas is burned by a burner and injected onto the surface of a solid substance. The thing which surface treatment is performed is known (for example, refer patent document 1).

  In the surface modification processing apparatus of the type as described above, a storage tank for storing the modifying compound, a storage tank for storing the flammable gas, a mixing chamber for mixing the reforming compound in a gaseous state and the flammable gas, and the like An injection section (burner) for injecting the fuel gas mixed in the mixing chamber is required. For this reason, many types of surface modification treatment apparatuses of this type are large and stationary. When the surface modification treatment apparatus is a stationary type, there is a problem that an installation space is required and the surface modification treatment can be performed only at a place where the apparatus is installed (see FIG. 1 of Patent Document 1). ).

JP 2003-238710 A

  Patent Document 1 also proposes a portable surface modification apparatus using a cartridge-type storage tank. By using a cartridge-type storage tank, the apparatus can be downsized (see FIG. 3 of Patent Document 1).

  However, even with such a configuration, in addition to the cartridge-type storage tank, a pressure gauge, a flow meter, a case for housing these members, and the like are required, and thus further miniaturization has been demanded.

  Further, in the portable surface reforming treatment apparatus described in Patent Document 1, a fuel gas containing a cartridge filled with tetramethylsilane having a boiling point of 27 ° C., tetramethoxysilane having a boiling point of 122 ° C., and compressed air is used. A mixed gas is used (see paragraph [0060] of Patent Document 1). When two kinds of compounds with different boiling points and compressed air (gas) are contained in one cartridge (storage tank), the vaporized compounds (tetramethylsilane and tetramethoxysilane) and compressed air are not uniformly mixed. There is concern about being ejected from the container. As described above, when the reforming compound and the flammable gas are injected in a non-uniform mixed state, there is a problem that the combustion efficiency deteriorates and the surface modification of the solid substance becomes non-uniform.

  Furthermore, in the conventional surface modification processing apparatus, when performing the surface modification treatment, the storage tank is arranged in a manner other than the predetermined arrangement, such as by placing the storage tank upside down or laying down. However, there is a problem in that the reforming compound is not injected, or the reforming compound is injected in a liquid state without being vaporized.

  The present invention has been completed based on the above-described circumstances, and while reducing the size of the apparatus, the reforming compound and the fuel gas can be made uniform even if the orientation of the container containing the reforming compound is changed. It aims at providing the surface modification processing apparatus which can inject the flame burned in the mixed state.

  In order to solve the above-described problems, the present invention burns a modified compound having a metal atom, a metalloid atom or a nonmetal atom, and an organic group with a fuel gas in a burner, and the flame is applied to the surface of a solid substance. In the case of reforming the surface of the solid substance by spraying, the liquefied fuel obtained by liquefying the fuel gas and the liquid reforming compound are absorbed in a porous state in a mixed state and accommodated in a cylinder, In the surface modification treatment apparatus, a part of the mixed liquid absorbed in the porous material is vaporized and supplied to the burner.

  In the present invention, the liquid reforming compound and the liquefied fuel obtained by liquefying the fuel gas are contained in a cylinder in a mixed state (mixed liquid state). In other words, in the present invention, the reforming compound and the fuel gas are both in a liquid state, vaporized in a state of being uniformly mixed at a predetermined mixing ratio, and ejected from the cylinder. Then, the vaporized liquid mixture ejected from the cylinder is supplied to the burner. As a result, according to the present invention, a flame burned in a state where the reforming compound and the fuel gas are uniformly mixed at a predetermined mixing ratio can be injected onto the solid material, so that the surface of the solid material can be made uniform. It can be modified.

  Further, in the present invention, the reforming compound and the fuel gas are uniformly mixed and accommodated in one cylinder. Therefore, compared with the configuration in which the reforming compound and the fuel gas are separately stored, The number can be reduced, and only one device is required to control the amount of ejected matter ejected from the cylinder, so the number of parts can be reduced and the device can be downsized.

  Furthermore, in the present invention, the reforming compound and the liquefied fuel are absorbed in the porous material in a mixed state and accommodated in the cylinder, so that the porous material can be used regardless of the attitude of the cylinder. The absorbed liquid mixture of the reformed compound and the liquefied fuel is vaporized and supplied to the burner.

  As a result, according to the present invention, the apparatus is miniaturized, and even when the orientation of the container containing the reforming compound is changed, the flame burned in a state where the reforming compound and the fuel gas are uniformly mixed is injected. A possible surface modification treatment apparatus can be provided.

The present invention may be configured as follows.
The burner may be a Bunsen burner that sucks ambient air by ejecting a gas vaporized from the mixed liquid.
With such a configuration, it is possible to easily control the introduction of air and the amount of introduction of air, thereby easily controlling the combustion efficiency of the gas.

You may provide the replenishment port which replenishes the liquid mixture of the said liquefied fuel and the said modification | reformation compound to the said porous material in the said cylinder from the outside of the said cylinder.
With such a configuration, it can be used repeatedly by replenishing the mixed liquid from the replenishing port. Further, in such a configuration, since a necessary amount of the mixed liquid can be replenished, the cylinder can be reduced in weight and size, and the entire apparatus can be reduced in size.

  According to the present invention, a surface capable of reducing the size of the apparatus and injecting a flame burned in a state in which the reforming compound and the fuel gas are uniformly mixed even if the orientation of the container containing the reforming compound is changed. A reforming apparatus can be provided.
