Abstract

The utility model relates to aluminium alloy cylindrate explosionproof packing. The upper part of an aluminium alloy foil is evenly cut to form a plurality of seams at intervals and is provided with an upper regula (1) and a lower regula (4), and a seam strip is divided into a front semicircular regula (2) and a back semicircular regula (3). After the front regula (2) and the back regula (3) are across unfolded, the inside of the seam strip is provided with a unit body with a cylindrate pore structure. The utility model has high explosionproof performance, and the utility model can fully improve standard index which is equal to or less than 0.045 MPa and further reduce cost use. The utility model has the advantages of convenient filling, and the utility model can easily fill the whole space and can be easily filled in some special shaped volumes so as to decrease the ratio of remaining volume and enhance safe performance.

Description

The datonation-inhibition filler of aluminum alloy round column type

The utility model relates to a kind of explosion-suppressing material that is used for combustible and explosive articles, refers in particular to the datonation-inhibition filler of a kind of aluminum alloy round column type.

Chinese patent discloses a kind of " explosion-suppressing material that is used for combustible and explosive articles " (ZL92102437), its chemical component weight percentum of expansion aluminium foil is: Mn is 0.8～1.8, Fe is 0.3～0.7, Si is 0.3～0.6, Cu is 0.1～0.2, Zn is 0.1, Mg is 0.03～0.1, the Al surplus, this netted explosion-suppressing material is by joint-cutting and system folded by the aluminium foil after expanding or coiling forms, grid between layer and the layer is staggered superimposed with equidirectional, the several layers grid has formed unordered cross structure each other, is the superimposed body of the several layers of honeycomb-like pore structure, and the aluminium foil after this spherical explosion-suppressing material is also expanded by joint-cutting is made, outer surface smoother, inside is the spheroid of honeycomb-like pore structure.This patentee has applied for again a kind of " the datonation-inhibition holder of combustible and explosive articles " (ZL92206251), is that of above-mentioned patent uses example.These cancellated explosion-suppressing materials, though play datonation-inhibition preferably effect, particularly inconvenient more under the situation at special-shaped container in filling inconvenience in the container, and also datonation-inhibition function does not reach best; These spherical explosion-suppressing materials (datonation-inhibition ball) were not therefore seen in market so far owing to be that quite difficulty realizes on technology.

Task of the present utility model provides the datonation-inhibition filler of a kind of aluminum alloy round column type, its convenient filling, and purposes is wide, the datonation-inhibition function height.

For finishing above-mentioned task, the solution that the utility model is taked is: the datonation-inhibition filler of a kind of aluminum alloy round column type, on alloy foil, be cut into some seams evenly and at intervals, leave upper sid strip and lower sid strip, stitch bar and divide preceding semicircle edge strip and rear semicircle edge strip, the staggered inside, back that struts is the cell cube of cylindrical hole gap structure.

The utility model is made simple, make with above-mentioned patent (ZL92102437) material, its datonation-inhibition function is greatly improved than the Web materials that provides on the existing market, standard index can bring up to fully≤0.045MPa (the datonation-inhibition function standard of the Web materials on the existing market for≤0.11MPa), further reduced use cost; Convenient filling is filled up the entire container space easily, more easily is loaded in some special-shaped volumes, has reduced to stay capacity rate (promptly the volume that can't load accounts for the total volume ratio), has improved safe reliability.When using the utility model, with its by certain density mode be filled in that contain is inflammable, in the container of explosive liquid, in container when volatilization gas and air-blending reach the explosive limits scope, the accident of can not blasting when running into naked light, static, thunderbolt and accident and clashing accident.It can be used for the fuel transport car, the fuel tank and the oil tank of flow filling car, aircraft gas refueller, civil and military vehicle, aircraft, naval vessels are explosion-proof; Also can be used for the explosion-proof of inflammable and explosive media Containers such as various storage gasoline, diesel oil, banana oil, acetone.It has following characteristic: (1) can suppress gasoline, diesel oil, methane, ethane, propane, toluene, organic solvent etc. and blast in container.(2) this material is housed and alleviates static hazard effectively with the new type of metal container.(3) when container leakage of the present utility model is housed, is not forming under the explosive space condition and can directly carry out repair welding with gas welding, electric welding.(4) truck tanker of the present utility model is housed in transportation, can reduces the shaking degree of liquid.(5) the utility model container inner wall that do not wear and tear, itself is pollution-free, indeformable in container, not loss of burn in the oil plant equal solvent, but long-term use.(6) the utility model only accounts for and is filled with 1～1.7% of vessel volume (filling content), and addition is 28～30Kg/m ³

The utility model will be further described below in conjunction with embodiment and accompanying drawing.

Accompanying drawing 1 is the front view of present embodiment.

Accompanying drawing 2 is left views of present embodiment.

Shown in accompanying drawing 1～2, present embodiment is the datonation-inhibition filler of a kind of aluminum alloy round column type of 11 seam bars, on alloy foil, be cut into some seams evenly and at intervals, leave upper sid strip (1) and lower sid strip (4), stitch bar and divide preceding semicircle edge strip (2) and rear semicircle edge strip (3), the staggered inside, back that struts is the cell cube of cylindrical hole gap structure.The seam bar that cell cube had is decided on actual needs.

Claims (1)

1, the datonation-inhibition filler of a kind of aluminum alloy round column type, it is characterized in that: on alloy foil, be cut into some seams evenly and at intervals, leave upper sid strip (1) and lower sid strip (4), stitch bar and divide preceding semicircle edge strip (2) and rear semicircle edge strip (3), the staggered inside, back that struts is the cell cube of cylindrical hole gap structure.
