Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a melting apparatus suitable for melting a resin. More specifically, the present invention relates to a dissolving apparatus for efficiently dissolving a resin or the like when sampling an epoxy resin or the like and confirming and testing its physical properties and composition.

[0002]

[Prior art]

 To dissolve the test sample resin in the solvent, put the resin together with the solvent into a sample container such as a flask or beaker, and shake the container by hand or stir with a stirrer using a magnet type rotor to dissolve. Is usually promoted. If heating is required during this melting, operations such as shaking the flask by hand on a heating device such as an electric heater are performed.

[0003]

[Problems to be solved by the invention]

 Dissolution by such a method is disadvantageous in that it takes a considerable amount of time, takes a long time to dissolve, and the dissolution conditions tend to vary from container to container. In particular, it is difficult to make the heating conditions the same, and there is also a safety problem if the flask is manually shaken on an electric heater.

[0004] An object of the present invention is to provide a dissolving apparatus that can rapidly dissolve a large number of resin samples under the same conditions.

[0005]

[Means for Solving the Problems]

 The dissolution apparatus of the present invention includes a holder for holding a sample container, a heater for heating the sample container held by the holder, and a vibrating device for vibrating the holder.

FIG. 1 is a perspective view of a melting apparatus according to an embodiment, FIG. 2 is a longitudinal sectional view of a holder of the melting apparatus of the present invention, and FIG. 3 is a bottom view of the holder.

The melting device includes a casing 1 having a driving unit such as a vibration motor built therein, a vibration plate 2 installed horizontally on the upper surface of the casing 1 and vibrated by the driving unit, And a holder 3 made of a good heat conducting material such as aluminum or an aluminum alloy.

The vibration of the vibration plate 2 is normally linearly vibrated in the horizontal direction, but may be a horizontal rotational motion, or the amplitude or frequency may be changed with time. In addition, not only horizontal movement but also vibration such as vertical vibration may be used.

In the case of vibrating linearly in the horizontal direction, the frequency may be about 100 to 130 times / minute, and the vibration width may be about 1 to 8 cm.

The holder 3 is usually made of a metal block such as aluminum, and is provided with a plurality of (six in FIG. 1) holes 4 for holding a sample container 5 from the upper surface side. It is desirable that the hole 4 has a depth of about 50% to 90% of the height of the sample container 5. If the hole 4 is too shallow, the sample container may fall off due to vibration, and there is a disadvantage that it takes a long time to heat. If the depth of the hole 4 is too deep, it is difficult to perform visual observation even when the sample container 5 is a transparent container such as glass. When a bin having a height of about 110 mm is used, the depth of the hole may be about 60 to 80 mm.

It is preferable that the size of the hole 4 is usually larger than the diameter of the sample container 5 by about 2 to 5 mm for the sake of taking the container 5 in and out. Usually, a transparent container such as glass or synthetic resin is used for the container 5, but since the diameter of the container 5 may vary by about 1 to 2 mm depending on the product, the outer diameter of some sample containers 5 is measured. The hole 4 may be provided to be larger than the diameter of the thickest container by about 2 to 5 mm. If the hole 4 is too large, the thermal efficiency will deteriorate.

When the sample container 5 moves around in the hole 4 when vibration is applied, there is a risk of breakage. Therefore, it is preferable that the hole 4 is provided with a fixing member 11 for fixing the container 5.

Although the fixing member 11 is shown in the form of a leaf spring in FIG. 2, a heat-resistant synthetic resin such as silicon rubber is provided in an annular shape and the container is pushed in, or a coil spring as shown in FIG. A structure in which a biased contact member is provided to fix the container may be employed.

The shape of the hole 4 is usually circular, but when there is not much individual difference in the outer diameter of the container, a half of the hole as shown in FIG. The other half may be a hole having a slightly larger outer diameter to form a deformed hole which facilitates taking out of the sample container 5.

A heater 6 such as a sheath heater is provided between the holes 4 of the holder 3. The heater 6 is preferably provided by being inserted into the hole 15 of the holder 3 as shown in the figure. The hole 15 is preferably provided from the lower side of the holder 3, but may be provided from the upper side or the side. In any case, the heater 6 may be inserted at an intermediate position between the holes 4 for holding the sample container 5 provided in the holder 3.

A hole 16 provided in the vicinity of the hole 15 for the heater 6 is for buffering heat from the heater 6, and is used for buffering a temperature for facilitating the temperature control by facilitating the transmission of heat. Things.

The holes 15 for the heater 6 may be provided as appropriate depending on the length and thickness of the heater 6, and the temperature buffer holes 16 are provided around the hole 15 for the heater 6 in a number of 10 to 10 per hole 15. It is sufficient to provide about each.

Since the holder 3 is sometimes heated to 100 ° C. or higher by the heater 6, it is preferable to provide a protective cover 12 that covers the periphery of the holder 3. This protective cover 12 is usually made of a metal plate (punching plate) having a large number of holes 14 or a metal net. Such a cover may be attached with bolts 13 or the like so as to keep a certain distance from the surface of the holder 3. The cover 12 can prevent burns and other accidents during the work of mounting and removing the sample container 5.

It is preferable to use a transparent container such as glass for the sample container 5 from the viewpoint of easily confirming the state of the internal sample.

In addition, when the sample container 5 is heated when the lid is closed, the solvent or the like evaporates and the internal pressure of the sample container 5 increases, which may cause a rupture accident. There is a method such as providing a hole in the lid and loosely closing the lid.However, it is better to adopt a structure in which a small opening is provided in the lid, etc. .

The holder 3 is provided with a heater 6 such as a sheath heater so that the sample container can be heated via the holder 3. The heater 6 is connected to a temperature controller 10 via leads 7, 9 and a relay terminal 8.

Although a heat insulating material is provided in the vibration plate 2, the vibration plate 2 itself may be made of a heat insulating material.

In order to dissolve a sample using the dissolution apparatus configured as described above, a resin sample and a solvent are put in a sample container 5, and the sample container 5 is put in the hole 4 of the holder 3. Next, the switch of the drive unit is turned on, and the diaphragm 2 is reciprocated horizontally. In addition, the heater 6 is energized to uniformly heat the solvent in the sample container 5.

Thus, the sample in each sample container 5 can be dissolved under uniform conditions (stirring strength and temperature). In the above embodiment, a sheath heater is used as a heater, but another heater may be used. In the device of the present invention, oil or water may be used as the heat transfer medium depending on the melting temperature.

In the above embodiment, the vibration plate 2 is vibrated horizontally, but it may be rotated or vibrated in the vertical direction.

The dissolving device of the present invention is suitable for dissolving resins such as polyester resins, vinyl ester resins, and phenol resins in addition to being used for analysis of epoxy resin samples, but for dissolving gels and viscous materials. Can also be used.

[0027]

[Effect of the invention]

 As described above, according to the dissolving apparatus of the present invention, a large number of samples can be rapidly and individually dissolved under the same conditions.
