Next, the steps are performed, and the foam is rolled by a roller to produce an open-cell foam. The method for producing the foam body is to use the equipment to break the foam of the foam to increase the pressure resistance of the open-cell foam, thereby increasing the usability, but the upper 2 is foamed by a fine needle or a roller. The opening direction of the foaming pores of the body is perpendicular to the water and the water is changed. Although the manufacturing method can increase the force and pressure, but the effect is limited, there is still a need to = 'such as == the above _ and the _ touch The body properties of the high-pressure open secret foam. Knowing the foam, and improving the foaming property, and further increasing the foaming. [Inventive] The object of the present invention is to provide a product for producing a (four) pressed open-cell foam. Further, the foam is increased, and the foam is increased. The method for producing the open-cell foam having a high withstand voltage according to the present invention, (4) the method includes a polymer; heating the polymer to foam the polymer to produce a hair · The 201028440 wheel and the lower roller are rolled into the foam to produce an open-cell foam; wherein the present invention foams the plurality of foams by the rotational speed of the upper roller being different from the rotational speed of the lower roller. The pores are broken and the opening directions of the foamed pores are not perpendicular or horizontal. [Embodiment] In order to give the reviewer a better understanding and understanding of the structural features and the effects achieved by the reviewer, please refer to the preferred embodiment and the detailed description. For details, please refer to the third figure. Is a flow chart of a preferred embodiment of the present invention. As shown in the figure, the method for manufacturing a high-pressure-resistant foam of the present invention first performs a step S10 to provide a polymer, and the polymer in the polymer The material can be ethylene-ethylene acetate copolymer (EVA), styrene-butadiene rubber (SBR), a natural rubber (NR), acrylonitrile-butadiene rubber (NBR), and ethylene propylene. - non-conjugated diene rubber (EPDM), butadiene rubber (10), a polyethylene (tetra), a polystyrene (ps), - polyethylene (PVC), - polyurethane (PU), agglomerate Propylene (pp), monobutane rubber (CR), isoamylene rubber (IR) or a styrene-butadiene-styrene elastomer (SBS). Then, step S12 is performed to heat the polymer to foam the polymer to produce a foam HK as shown in FIG. 4A, wherein the temperature of the heated polymer is 22 degrees Celsius, and the polymer is easy to be polymerized. The process of foaming is performed to generate a plurality of foaming gas 12 in the interior of the polymer to form the foamed carcass 10, and then step S14 is performed, and at the same time, and referring to FIG. 4B, is the open-celled hair of the present invention. Schematic diagram of the action of breaking the bubble body, as shown in the figure, this step is a process of breaking and foaming the foaming pores 12 of the foam 10 by a mechanical means to produce the open-cell foam 20, And the opening direction of each of the foaming pores 12 of the open pore foam 2 after the foaming pores 12 is not perpendicular or horizontal, that is, the opening direction of the foamed pores In the case of the "inclined direction", the pressure resistance of the foam 1 可 can be increased, and the usability of the body 10 can be increased. % is connected to the above-mentioned 'the mechanical direction of the direction in which the opening direction of the open-cell foam 20 is inclined, which includes an upper roller 30 and a lower roller. The upper roller 30 is disposed above the lower roller 32. Above the bubble body 10, the lower roller 32 is located below the foam 1〇, and adjusts the rotational speed of the upper roller 30 and the rotational speed of the lower roller 32, so that the rotational speed of the upper roller 3〇 is different from 201028440 at the lower roll=32 The rotational speed, that is, the rotational speed of the upper roller 30 is greater than the rotational speed of the lower roller 32, or the rotational speed of the upper roller 30 is smaller than the rotational speed of the lower roller 32. In this embodiment, the rotational speed of the lower roller 32 is greater than that of the upper roller 32. Since the speed of the rotation of the roller is such that the foam 1 is rolled by the upper roller 30 and the lower roller 32, the foam 1〇 is inclined in the direction of the lower roller, and the foam 20 is produced. The foamed pores 12 of the open-cell foam 2 产生 which are produced by rolling the foam 1 破 are all broken in the direction from the upper left to the lower right. As described above, in the present invention, the two-roller 〇 32 is used to roll the foam 1 〇 to produce an open-cell foam, which increases the resistance of the open-cell foam ’ and further increases the usability of the open-cell foam 20 . Further, the direction of rotation of the upper roller 3〇 is different from the direction of rotation of the lower roller 32, so that the rolling speed of the foam 10 is increased, and in this embodiment, the direction of rotation of the upper roller 20 is clockwise, and The direction of rotation of the roller is the counterclockwise direction. Among them, the speed ratio of the open-cell foam 20 produced by the ratio of the speed between the upper roller 3 〇 and the lower roller 2 〇 — 5 - 1 可以 can achieve the best effect. Furthermore, please refer to the third figure. Since there are many ways to manufacture the foam 1 ,, the present invention provides a preferred one for manufacturing the hair 1G, but it is not in this embodiment, please __ Referring to Figure 5, a flow chart for making a foam of the preferred embodiment of the present invention.
