Description
The present invention relates to the datonation-inhibition packing material in flammable and combustible liquids or the gas reservoir, belong to functional metallic material.
At present, in liquid, gas fuel and inflammable and explosive fluid reservoirs such as gasoline, propane, acetylene, ether, behind the installation hole gap material, utilize the heat absorption of this material and inhibitory action can increase the safety of this container in accident effectively.
Known US Patent 3356256 " explosive safe fluid container " is a kind of packing material that is used for explosive fluid container.This material is to be combined by coarse mesh and two kinds of expanded metal of fine mesh, and used expanded metal is the aluminum alloy that contains beryllium and titanium.The pack density of this packing material in container is 52.4Kg/M
3, the volume ratio that accounts for container is 1.937%, is full of with this material basically in the container.Another packing material that US Patent 4149649 " datonation-inhibition thing " proposes, similar to above-mentioned 3356256 proprietary materials, in order to reduce density of material and to increase material stiffness, only done improvement on the method stacking of web material compartment, this effect of improving one's methods is in use not remarkable, and particularly the density of material there is no significantly and reduces.In use also need be full of container, and the manufacture craft of this material is complicated.US Patent 4613054 " is used for flammable fluid weighting material and manufacture method ".It is a kind of ball packing, solved preferably and be difficult for the problem of packing into and taking out when existing container uses this material, but the maximum deficiency of this material is the volume ratio big (generally being not less than 5%) that occupies container, thereby has limited practicality greatly, and service efficiency is low.
The objective of the invention is, a kind of suppress flammable fluid burning and the netted and spherical explosion-suppressing material that explodes in the container are provided.This density of material is low, and it is little to occupy volume, and manufacture craft is simple, and cost is low, and good combination property is convenient to pack in container and take out, and is easy to use, safe and reliable.
The present invention is used for the explosion-suppressing material of combustible and explosive articles, and its chemical analysis percentage by weight is: Mn is 0.8～1.8, and Fe is 0.3～0.7, and Si is 0.3～0.6, and Cu is 0.1～0.2, and Zn is 0.1, and Mg is 0.03～0.1, the Al surplus.Make aluminium foil according to technological requirement, its manufacturing process flow is as follows:
Aluminium alloy ingots → rolling → alloy foil → netted the explosion-suppressing material of grooving machine joint-cutting → joint-cutting aluminium foil → shaping → coiling shaping → cylinder of mesh scroll → net puller expansion → aluminum foil web → folded make the netted blank of the netted explosion-suppressing material of shape → rectangle lamination shape → cutting shaping → make → → marble forming machine system ball → spherical explosion-suppressing material
The explosion-suppressing material of netted combustible and explosive articles of the present invention is to be made through technologies such as superimposed or coilings by the aluminium foil after joint-cutting and the expansion, and whole material all has similar cellular pore configuration from inside to outside.
The explosion-suppressing material of spherical combustible and explosive articles of the present invention is to be made through operations such as punching presses by the aluminium foil after joint-cutting and the expansion, and it is roughly level and smooth that it has an outside face, and inside is the spheroid of similar cellular pore configuration.
Below in conjunction with accompanying drawing the present invention is further described:

Fig. 6 is the embodiment scheme drawing of spherical explosion-suppressing material;
As shown in Figure 1: 1 is material of aluminum foil, makes the explosion-suppressing material of netted combustible and explosive articles, and its thickness is selected 0.02～0.2mm.Make the explosion-suppressing material of spherical combustible and explosive articles, its thickness is selected 0.04～0.2mm, and its width is 50～800mm.2 is the joint-cutting that cuts on aluminium foil through grooving machine, the length A of cutting, and being used for netted explosion-suppressing material is 8～25mm.Being used for spherical explosion-suppressing material is 10～25mm.Joint-cutting vertically is being discontinuous, laterally is being staggered symmetric offset spread, and the fore-and-aft distance B(between joint-cutting is the length of connecting portion) be 2～6mm at netted explosion-suppressing material.At spherical explosion-suppressing material is 2～8mm.Transverse distance C(between joint-cutting is that muscle is wide) be 1～2.5mm at netted inhibition material.At spherical explosion-suppressing material is 1～3mm.
As shown in Figure 2: 3 is the connecting portion between grid, and its width D is 2～5mm at netted explosion-suppressing material, is 2～6mm at spherical explosion-suppressing material.4 for forming the muscle of grid with connecting portion, its width is 1～2.5mm at Web materials, is 1～3mm at spherical explosion-suppressing material.The length E of the prism mesh that single grid is formed is 6～22mm at netted explosion-suppressing material, is 8～22mm at spheroidal material.
As shown in Figure 3: 5 and 6 is adjacent two layers of mesh compartment, the muscle 7 of levels and 8 interlocks superimposed, every layer of grid and adjacent grid have been formed with the interlaced structure of same direction, when the several layers grid is superimposed, muscle between lamination and connecting portion are asymmetric state substantially, but the superimposed direction of each layer grid all is basically identicals, and promptly the length of prismatic grid such as the E among Fig. 2 all are parastate and arrange, and has formed the unordered staggered cellular pore configuration that is similar between multi-layer net.
As shown in Figure 4: 9 is the outer layer net compartment of netted explosion-suppressing material, 10 is the mid-level net compartment, net volume is the single layer mesh of making by the selection size of Fig. 1 Fig. 2, adopts the described method of Fig. 3 through coiling or foldedly make shape, and whole net volume all goes out similar cellular pore configuration from inside to outside and forms.The netted explosion-suppressing material of cylinder scroll can be as requested, both can be superimposed or turn to rectangle or other shape, but also sawing is other needed shape.
As shown in Figure 5: 11 is the shape of single spherical explosion-suppressing material, it is to be made through operations such as system balls by netted blank, its external diameter is 12～80mm, the aluminium foil band 12 that constitutes spherical explosion-suppressing material is made up of muscle in the netted blank and connecting portion, ball 11 is to be made of bonded assembly band 12, and the inside of ball is similar cellular pore configuration, and the outside face of ball is level and smooth basically, so can guarantee the usage safety performance of material, be convenient to again in holder, spheroidal material be packed into or take out.
As shown in Figure 6: the weighting material of being installed in the portable holder 13 14 is netted explosion-suppressing material, 15 is the oil drum handle, and 16 is the holder geat, because of holder 13 is cylindrical, so installed the netted explosion-suppressing material of cylinder scroll, the load mode of this material is to pack into simultaneously at the making holder.Spherical explosion-suppressing material then can be directly packed into or is taken out from the holder perfusing hole of making, and the running condition of spherical explosion-suppressing material is that a plurality of balls stack in holder naturally.
