Abstract

PURPOSE:To enable to transfer resin whose foams are few to a desired place, by a method wherein a vessel provided with a decompression device is installed on a high place in the vicinity of the aimed place, and after the resin has been sucked and transferred by decompressing the inside of the vessel the resin is transferred by dropping the same to the aimed place based on gravity. CONSTITUTION:The inside of a decompression tank 1 is decompressed by a decompression device 1a, resin 4 is sucked and transferred within the decompression tank 1 through a resin supply opening 1b and the resin 4 is passed through a passage 1c by turning the same into a state of a thin film. When the resin 4 is turned into the state of the thin film, it becomes that a foam in the inside of the resin is apt to be removed. The resin 4 accumulated within the decompression tank 1 is fed onto a base material 7 by making use of gravity. Then the resin 4 is dripped to the base material 7. As the titled method is so constituted that the resin is transferred by making use of a pressure difference and the gravity and it does not happen that an impeller of a pump does not abut against the resin like a case wherein the pump is arranged within piping like this, it is hardly feared that the form is rolled in the resin. As deaeration, moreover, is performed also within the decompressed tank, the resin whose foams are few can be fed to a desired place and a place for using it.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a method for transferring resins used in chemical, unesaka, layered materials, and FRP.

[Background technology]

A decorative board obtained by laminating and molding a laminate of a number of resin-impregnated base materials obtained by impregnating a product with a resin-impregnated varnish and drying it according to the taste, using no pressure or pressure. , itt
In laminates, FRP, etc., the air bubbles contained in the resin-impregnated base material reduce the heat resistance, air performance, and strength of the laminate, and the removal of air bubbles is a major problem that affects product prices. Met. For this reason, depressurization treatment of resin varnish, depressurization treatment of resin-impregnated base materials, etc. are carried out, but in the case of i\i1, the resin varnish treated with depressurization is sent 4 times using a pump, so it is difficult to avoid air bubbles from being mixed in. In the case of the latter, the resin-impregnated base material during transportation had to be subjected to vacuum treatment, which made it extremely difficult to achieve an airtight seal.

[Purpose of the invention]

The object of the present invention is to provide a method of transporting resin with few bubbles to a destination.

[Disclosure of invention] The present invention is used to transport resin to a destination.

Place equipment equipped with decompression means at a high place near destination H.
F”A is characterized in that the pressure inside the container is reduced and the resin is suctioned and transferred, and then the resin can is dropped and transferred to a destination location based on gravity.
Since a pump is not used in the resin transfer method, it is possible to prevent air bubbles from being mixed into the resin.One embodiment of the present invention will be described in detail below based on an excerpt.

Figure 31 is a commercial schematic diagram of the transfer device used to carry out the clear transfer method showing an embodiment of the present invention. 1.#'

In the decompression dunk, a decompression means im consisting of a direct air pump and a resin supply port 1b are connected to the ceiling. Further, inside, a diffusion plate 1a is provided in a zigzag pattern downwardly for making the resin 4 into a thin film state, and the phenol Iv-111 sucked from the resin supply port lb is disposed in a zigzag manner.

Furthermore, the r4 offering supply 1b connected to the ceiling of the decompression gunta 1 has an arm 6 whose lower end faces the bottom of the resin pan 3.
f-continued. On the corner of the tree-shaped reservoir 2, there is a piping 8 whose lower end faces above a strip-shaped elongated base material 7 used for decorative boards, laminates, FRP, etc. A resin pan 3a is installed in the resin pan 3. In 1g, 9 is Vap, lO

are shown respectively. Incidentally, the decompression dunk 1 may be a device such as a pipe equipped with a decompression means. Using this transfer device, the resin transfer method according to the present invention is practiced, for example, as follows. First, prepare Resin 4 by adding curing agents, catalysts, solvents, colorants, surfactants, fillers, etc. as necessary to the raw resin. do. When preparing the resin, stir it with a depressurizing means such as a direct air pump.The air bubbles in 1 + 1f 4 can be easily removed and removed, making it possible to obtain resin 4 that contains almost no air bubbles. leave.

Next, the pressure inside the vacuum dunk 1 is reduced by the pressure reducing means 1a, and the E-recording finger 4 is sucked and transferred into the vacuum tank 1 through the resin supply port 1b. At this time, the nurse 4 sucked into the decompression dunk 1 is made into a thin film state and transferred to the passage 1e. tree nji 4e
This is because when tf is set to 4-4, the air bubbles in 1 x 1 x 4 are easily removed. Resin 4 accumulated in the pressure tank l
feeds the base material 7 one step above using gravity.

Then, the resin 4 is poured onto the base material 7. After applying the resin-impregnated material 7' in this manner, a predetermined sheet of the resin-impregnated material 71 is applied with a squeeze row M or a laminated row I.
At t/11, tJI is applied to form a product 1;/j, and the product is cured and cut into a predetermined size to obtain a laminate or the like. The grease flowing out from the resin gold a base material 7' is received by the #ir grease 9 3a, stored in the resin pan 3, and can be sucked and transferred to the vacuum gun 1 for reuse if necessary. be.

As described above, the resin transfer method according to the present invention uses pressure difference and vehicle power to transfer the resin, and is similar to the case where a pump is placed in the piping (4 resin feed lines). Also, I have never had a pump blade come into contact with resin. Therefore, there is little possibility that air bubbles will be blown into the resin. What's more, defoaming is also carried out in the depressurized tank. If the resin is made into a thin film during the transfer so that air bubbles and the like caught in the resin 1 during transfer can be removed, the 4@ fat with even fewer air bubbles can be sent to the place of use.

The passage through which the resin is made into a film does not necessarily have to be located within the tank. However, if a passage is arranged in a container equipped with a pressure reducing means and the conger fat is made into a thin film under reduced pressure, defoaming can be easily carried out.

〔Effect of the invention〕

The uninvented 1:g filtration method for resin involves placing a container equipped with 4+'J pressure reducing means at a high place near the destination, and reducing the pressure inside the container to remove the resin. After the resin is suctioned and transferred, the resin is dropped and transferred to the destination location based on one gravity, so it is possible to send the resin with few air bubbles to the destination location and use location.
