Abstract
The utility model relates to separating explosion-proof filler. Gaps are formed by cutting aluminium alloy foil and the aluminium alloy foil expands into a prismatic net shape, then the aluminium alloy foil is folded or wound to a honeycomb shape to form the separating explosion proof filler, grids among the layers of the aluminium alloy foil are overlapped in a staggered mode, and a plurality layers of grids form a unordered staggered structure with each other. The aluminium alloy foil is formed by the following metallic components, by mass percent: 1.0% to 1.2% of Mn, 0.4% to 0.6% of Fe, 0.4% of Si, 0.02% to 0.06% of Cu, 0.02% to 0.03% of Ti, and the balance Al, wherein the sum of the mass percent of Mn and the mass percent of Fe is 1.6%. The aluminium alloy foil of the separating explosion-proof filler is high in intensity, good in malleability, high in ductility and stable in mechanical property of alloy, the separating explosion proof filler has enough intensity, is easy to process and form, and not prone to being damaged and drop fillings in a filling and using process, and therefore safety is improved and the effect of intrinsic safety can be achieved.
Description
Technical field
The utility model relates to a kind of be used to being filled in the inner material of flammable and combustible liquids or gas storage container (as petrol storage tank etc.), is the explosion-proof Charge of a kind of obstruct specifically.
Background technology
Be used for holding inflammable, explosive liquid or gas containers at blast and the fire stored, transportation causes easily owing to contingencies such as static, naked light, gunslinging, bumps.Fire-retardant datonation-inhibition Charge of the prior art all is vertical joint-cutting cross directional stretch, and the space of generation is inhomogeneous, and monolithic can not form spatial structure, and material subsides easily, falls bits, thereby is deposited on container bottom after the breakage.And the alloy foil that these explosion-suppressing materials adopt, its metallic element kind that be used for to strengthen intensity and ductility is more, so price is higher, and still there are defective in the intensity in the mechanical property of product and ductility, stretch ratio etc., the stable mechanical property of alloy is poor, and is not very good.
Summary of the invention
For solving above-mentioned technical matters, the utility model provides a kind of obstruct explosion-proof Charge, the explosion-proof Charge of described obstruct has by the folding space network that forms that rolls of mesh-structured alloy foil, layer is staggered superimposed with the mesh between the layer, and the mesh between some layers of alloy foil interlocks superimposed and forms unordered cross structure.
In technique scheme, the mesh-structured of alloy foil is to stretch along the vertical direction with joint-cutting behind the alloy foil joint-cutting to expand formed prismatic mesh-like structure again.
In technique scheme, the mesh-structured of alloy foil is the three-dimensional honeycomb net structure of individual layer.
In technique scheme, the explosion-proof Charge of described obstruct has by the folding space network that forms that rolls of the mesh-structured alloy foil of multilayer, adopts the mesh interlace mode superimposed and form unordered staggered mesh-structured between the mesh-structured alloy foil of described multilayer.
In technique scheme, the explosion-proof Charge of described obstruct is the netted cylinder bodily form or spherical or cuboid.
In technique scheme, the thickness of described alloy foil is 0.07mm-0.27mm.
The utility model has been obtained following technique effect:
Alloy foil intensity height, ductility is good, stretch ratio is high, and the mechanical property of alloy is more stable, makes that intercepting explosion-proof Charge has enough intensity, be easy to machine-shaping, cracky does not fall bits in filling and use, thereby improves safety, can reach the effect of essential safety.
Description of drawings
Fig. 1 is the structural representation behind the alloy foil joint-cutting of the present utility model.
Fig. 2 is the local structure scheme drawing after the alloy foil stretching of joint-cutting is expanded.
Fig. 3 is the structural representation after the explosion-proof Charge of obstruct of the present utility model rolls.
The specific embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
The utility model provides a kind of novel obstruct explosion-proof Charge, forms by having folding the rolling of mesh-structured alloy foil.At first along alloy foil laterally with the alloy foil joint-cutting, as shown in Figure 1, again along with the vertical direction stretching alloy foil of joint-cutting and be extended to the prismatic mesh, form the three-dimensional honeycomb net structure of individual layer, as shown in Figure 2, the folding three-dimensional shape that rolls into any appropriate such as cylindrical, spherical, cuboid that twines again, as shown in Figure 3, this moment, the alloy foil layer was staggered superimposed with the mesh between the layer, and some layers mesh-structured forms unordered cross structure each other.The explosion-proof Charge of made obstruct is filled in the container that holds inflammable and explosive dangerous goods, also the cancellated alloy foil of three-dimensional honeycomb that forms individual layer directly can be adopted the filling mode of laying be filled in the container that holds inflammable and explosive dangerous goods without winding, improve its explosion-proof with the container that is full of arbitrary shape.
The metal ingredient percent by weight of this alloy foil is preferably:
Mn is that 1.0～1.2, Fe is that 0.4～0.6, Si is that 0.4, Cu is that 0.02～0.06, Ti is 0.02～0.03, and surplus is Al.
Wherein: the percent by weight sum of Mn and Fe is 1.6.
The content of each metallic element does not require and is defined as definite percent by weight value, only requires within institute's restricted portion.
The explosion-proof Charge of the obstruct that the utility model provides utilizes the fitfull honeycomb net structure can be with inflammable, explosive liquid or gas barrier in very little relatively independent space, still have between these relatively independent spaces the hole, the seam be interconnected, thereby utilize the heat-conduction effect of its material, flame to be subjected to inhibition effect, the effect of free radical " wall absorption ", and effects of reduced temperature can destroy the pacing factor that forms combustion explosion, the bamboo telegraph of obstruct flame and the abrupt release of energy.The material of this alloy foil can be captured the free radical in the flaming combustion process simultaneously, farthest reduces thermal radiation, destroys the explosion condition of combustion medium.
The thickness of this alloy foil is at 0.025mm-1.5mm, preferably at 0.07mm-0.27mm.The alloy foil face area of producing in this scope is big, and the volume that takies liquid or gas is little, makes that intercepting explosion-proof Charge has enough intensity, be easy to machine-shaping, cracky does not fall bits in filling and use, thereby improves safety, can reach the effect of essential safety.
Above embodiment only is a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Its concrete structure and size can be adjusted according to actual needs accordingly.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
