Description of the Invention: [Technical Field] The present invention relates to a fluid-impermeable and heat-insulating fixture that is incorporated in a standard structure (preferably, a casing of a container), wherein The wall of the mount seen from the inside to the outside in the widthwise direction comprises: a primary fluid barrier layer in contact with the fluid contained in the mount, and a primary insulating layer. [Prior Art] These mounts incorporated in the structure of the vessel are suitable for the production, storage, loading, marine transport and/or unloading of cold fluids such as liquefied gases, especially gases having a high methane content (such as LNG). (Liquefied Natural Gas ^ LNG Marine transport at very low temperatures allows LNG to evaporate at a high rate, making it necessary for excellent liquefied gas insulation during the voyage. Known for various reasons (for example, by accelerating or speeding up) Or by braking or decelerating, by high-speed cornering; or by sudden steering caused by (near) collisions), the goods in the transportable tanks of tank trucks and road trucks may exhibit undesirable dynamic behavior, The dynamic behavior may even cause the vehicle to tip over. This effect depends in large part on the type of cargo contained in the storage tank, truck or tanker. For example, the freely movable (low viscosity) liquid is experiencing sudden The tanker will be easily brought into motion during handling. The liquid can be moved or shaken before and after it can supply additional momentum, thereby accelerating the tanker or truck. Overturned. Due to statutory regulations established to prevent sloshing or oscillation of liquid in the axial longitudinal or driving direction of the groove, in 161096.doc 201241346, a fixed seat internal mounting partition having a volume above a certain limit These baffles have the disadvantage that they only inhibit axial liquid movement so that non-axial movement of the liquid (such as radial or tangential movement) will not be inhibited or only inhibited. Moreover, these plates have their own The quality and volume are reduced to a small extent to reduce the capacity of the mount. In addition, these plates are usually fixedly mounted inside the mount, making labor-intensive internal installation, inspection, repair and cleaning necessary. The fixedly mounted plate inside the mount will transfer the energy of one part of the impulse and the oscillating liquid to the fixed seat and the fixed seat wall. Used for water transport and/or for marine fluid (liquid and gas) storage. In tankers, due to the surge of water and the ups and downs of ships on the water, liquid swings and sloshing may also occur. Gas carriers such as LNG carriers or vehicles Generally containing two or more mounts in which the gas which is cooled and condensed into a liquid at a temperature of about 丨62丨c at atmospheric pressure is stored and/or transported. The mounts may be "self-supporting" Type (usually in the shape of a sphere) or "film" type. The "membrane" type holder is directly supported by the outer shell of the container and integrated with the support structure of the container. These "membranes" supported by the outer shell of the container are fixed. The seat has a lower resistance to the force exerted by shaking the liquid inside and is therefore less suitable for use at sea. In the "membrane" type of seat, the gas to be transported exists in a liquid state and a vapor state at atmospheric pressure. The liquid "boiling" due to the energy supplied from the outside and also due to the energy absorbed in the liquid caused by the sloshing or surge of the liquid product. In the gas carrier The oscillating or rocking of the liquid in the mount depends on the surge of water and on the loading of the gas carrier. When the loading level increases by 161096.doc 201241346, the ship is deeper in the water and the frequency of the ship and the frequency of the goods in the fixed seat as well as the vibration and oscillation frequency will change. In gas carriers, the following effects also occur: sloshing and shaking of the liquid will cause energy absorption and thereby cause the liquid to evaporate, requiring additional cooling or otherwise removing excess energy. In the following, the term LNG carrier or gas carrier means storage and/or transportation of liquefied gas. All of these effects make it impossible to take full advantage of the capacity of the reservoir and thereby substantially reduce the fill rate to a value between 10% and 75%. This situation leads to operational constraints, especially for round-trip transport vessels operating in the spot market, which are not capable of unloading or loading commercially necessary or operating quantities of gas (eg 'because it is not possible to moor to the buoy) , thereby attributed to the loss of the transaction caused by the maritime conditions. Further, in the oil and gas field mining using the LNG carrier as a floating reservoir close to the borehole, the maximum capacity is required in the wave or wave of water to the greatest possible stability. Transport is also used in so-called "regasification" where ambient heat is used to evaporate cold liquefied (natural) gas and deliver it to consumers. The liquefied gas constitutes a liquid-gas balance in the fixed seat depending on the temperature and pressure. The pressure and foxness are selected such that the gaseous 2 ° 在 in the mount under atmospheric conditions essentially appears as a boiling liquid. The free space above the liquid is thus completely filled with vapor or gas of the product in liquid form. The wall of the "membrane" mount with fluid impermeability and thermal insulation is constructed by several layers from the inside to the outside in the widthwise direction. First, the main fluid barrier layer is applied. The main fluid barrier layer is in contact with the cold fluid. . The primary gripper barrier layer is constructed from a foil having a thickness of about q i and / 16J096.doc 201241346 or a metal foil and/or metal film. Since the metal expands and contracts as the temperature changes, a complicated connection between the sheets is necessary, and the sheets must have a zigzag or corrugated structure to prevent cracking or tearing. This situation renders this primary fluid barrier layer complex to manufacture and complicated to apply and therefore expensive. In addition, the wall of the "membrane" mount has almost no ability to receive and absorb shock and other forces generated by the sloshing liquid inside the mount. Accordingly, it is an object of the present invention to provide an unobtrusive fluid impermeable and heat-insulating mount that can be manufactured at low cost and that is capable of receiving and absorbing shocks imparted by liquid within the mount. And other forces. SUMMARY OF THE INVENTION This object is achieved by the present invention providing a wall of a fluid-impermeable and heat-insulating mount, wherein the material of the primary fluid barrier layer is a plastic that is flexible at low temperatures, the plastic being based on polyamine. And wherein the primary insulating layer is a layer of fabric 31) comprising two permeable fabric layers separated by a mesh layer or a layer of non-woven fibers. Comprehensive measures are taken to compensate for the expansion and contraction of the primary fluid barrier layer, not necessarily by the application of low temperature flexible plastics. It can be seen that plastics based on polyamines and aromatic polyamines or aromatic polyamines are particularly well suited for this purpose and are also known under the trade names Kevlar, Nomex and Twaron. The use of the fabric 3 layer has the advantage of achieving high heat insulation due to the large air ratio of the non-woven fibers, and also has the advantage of improving the shock absorbing effect by the non-woven fibers.

It is advantageous to configure this primary insulation layer from a fabric 3D layer, but it is also possible to assemble the insulation layer from two or more fabric 3D layers, which would generally result in lower cost. Preferably, the fixed seat wall is provided with a primary insulating layer having a material that will not become rigid or condense at low temperatures. In detail, kapok is selected for the material of the secondary insulation layer. An improved anti-vibration mounting wall is obtained by applying a layer of material such as kapok which will not condense or become rigid at the low temperatures used. "Kapok is a natural growth in the fruit of Ceiba pentandra." Hollow fiber. Preferably, a primary fluid barrier layer is provided on the exterior of the fabric 3D layer.

By this measure, a second fluid barrier can be easily mounted in the wall of the holder at a low cost. The fluid barrier layers can be easily joined to the fiber layers of the fibers 3d layer at a low cost in advance. This is also referred to as lamination. This embodiment is advantageous in that the non-woven layer of the fiber 3D layer of the fixed seat wall is a passage or hollow wall section for conveying the coolant. In particular, the channel or the hollow wall section extends over the entire circumference of the mount. More specifically, the passage or hollow wall section is provided with a supply pipe 161096.doc 201241346 for the coolant and a discharge pipe. Applying a fluid barrier layer to the fabric layer of the fabric 3 layer, a channel or cavity or hollow space is disposed in the wall of the fixture such that a coolant such as nitrogen can be transported from the supply conduit to the discharge A conduit to remove heat leaks from the environment and thereby reduce evaporation of liquid in the mount. Thereby, it is also possible to pressurize the passage or cavity by the coolant, so that the 3D layer of the fabric obtains greater hardness and increased mechanical strength. The invention will be further explained by the drawings of the wall of the holder and some embodiments, whereby features and other advantages will be obtained. [Embodiment] FIG. 1 shows a container provided with a holder for storing the liquefied gas 4. In this example, the container shown is designed to be particularly suitable for containing liquefied gases such as lng (liquefied natural gas). Hereinafter, an LNG carrier is used to indicate a gas carrier suitable for transporting liquefied gas. The LNG carrier is provided with components and facilities for maintaining the gas liquefaction and fluid insulation by maintaining the correct temperature and pressure in the holder. The holder is mounted on the double-walled casing 2 of the container and incorporated in In the double walled enclosure 2. The container floats in water such as the ocean. As seen in the traverse width direction, the wall 3 of the mount is constructed of several layers. The wall 3 of the holder is supported by the side walls and the bottom side wall of the container casing 2. In Fig. 2, 'from the left to the right in the thickness cross-sectional width direction, the fixed seat wall 3 and the container wall 2 are shown in more detail: it has the liquefied gas 4 and the main fluid barrier layer 5, the main fluid barrier layer 5 and the liquefaction Gas 4 contact. The fluid barrier layer 5 is preferably made of a plastic material that retains its flexibility even at low temperatures, such as the low temperature of LNG under atmospheric pressure at 161096.doc 201241346. The fluid barrier layer 5 consists entirely or predominantly of polyamine, such as a material known as nylon. The fluid barrier layer 5 can be a uniform layer (woven and/or non-woven) or can be composed of a woven carrier having an impermeable layer on one or both sides. The fluid barrier layer 5 can also be manufactured to contain a material based on an aromatic polyamide plastic. This plastic is also known as aromatic polyamine or aromatic polyamine, and is also known under the trade names Kevlar, Nomex and Twaron. As seen in the thickness direction of the (crossing width) in Fig. 2, the main insulating layer 6 is provided on the right side of the main fluid barrier layer 5, which is preferably based on the fabric layer, and is also known under the trade name "3mesh" of MiUler Texti丨. Ding the material. The fabric 3D layer contains a core mesh layer or a core non-woven fiber yarn between two open or permeable (woven) fabric layers. The primary insulation layer 6 may be constructed from a single fabric 3D layer or may be comprised of two or more three layers of fabric layers. A secondary insulating layer 7 may be provided between the primary fluid barrier layer 5 and the primary insulating layer 6, preferably having a non-condensing material such that the secondary insulating layer 7 will not become rigid at low operating temperatures The elasticity is retained such that the shock and other forces exerted by the fluid on this layer will be adequately received and absorbed. Preferably, kapok is selected for this material, which is a natural hollow fiber that does not condense or become rigid at its temperature. The fixed seat wall 3 may be provided with a second heat insulating layer 8 positioned between the main heat insulating layer 6 and the (dual) container wall 2. This insulating layer 8 protects the inside of the container wall 2 (usually a metal such as steel) from temperatures below the minimum permitted value for the metal. Again, the fabric 3D layer can be provided with secondary fluid barrier layers 6a, 6b, and the secondary fluid barrier layers 6a, 6b are provided on the exterior of the permeable fabric. The current fluid barrier layer & 6b 161096.doc 10 201241346 can be attached to the permeable fabric layer of the fabric 3D layer 6 by bonding, gluing or lamination. The secondary fluid barrier layers 6a, 6b may also be provided or laminated to both outer sides of the fabric 3D layer 6" Figure 3 shows fluid imperviousness with channels or hollow spaces or cavities for transporting coolant. An alternative embodiment of the fixed seat wall 3 of the adiabatic mount. Preferably, nitrogen is selected as the coolant. When the fluid barrier layers 6a, 6b are attached to the permeable fabric layer of the fabric 3D layer, the non-woven layer can be used as a fluid passage for a coolant such as nitrogen. By flowing the coolant from the supply conduit 9 to the discharge conduit 1 , thermal infiltration from the environment can be removed, so that evaporation of the liquid 4 in the reservoir is reduced. With the coolant, it is also possible to provide an excessive pressure in the passage or cavity to give the fabric 3D layer greater hardness and increased mechanical strength.
