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, gaseous 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 type of material, but the maximum deficiency of this material is the volume ratio big (generally being not less than 5%) that occupies container, thereby having limited practicality greatly, service efficiency is low.In addition, US Patent 5000336 " explosion protection that is used for container " also discloses a kind of datonation-inhibition weighting material.This weighting material has two kinds of basic structures.A kind of is to make size and arrange equal fitfull joint-cutting on the paper tinsel band, and then expands to the equal fitfull paper tinsel of size of mesh opening, shape and arrangement net, makes the datonation-inhibition obturator with irregular mesh again with this paper tinsel net.Another kind is punching out on the paper tinsel band, bends, molds many shapes and arrange equal fitfull perforate, and then the folded datonation-inhibition obturator with irregular perforate of making.Maximum characteristics on these two kinds of filling structures are that its fitfull mesh (or perforate) is to be formed by equal fitfull grid of the size of making on the paper tinsel band, shape and arrangement or perforate.These two kinds of structures are being better than such scheme aspect the stability (rigidity) that keeps datonation-inhibition obturator.But the method for making of preceding a kind of structure is complicated, and owing to size, shape and the arrangement of joint-cutting on the paper tinsel band are all irregular, causes being extended to difficulty of net.A kind of structure in back is subjected to the restriction (perforate can not be a lot of on the unit area) of its boring method except that making complexity, mesh can not be very tiny to cutting apart of space, thereby its datonation-inhibition function must be subjected to very big the influence in the use.
The objective of the invention is; Provide a kind of and can suppress flammable fluid burning and the netted and spherical explosion-suppressing material that explodes in the container, 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 → grooving machine joint-cutting → joint-cutting aluminium foil → shaping → netted the explosion-suppressing material of coiling moulding → cylinder of mesh scroll → net puller expansion → aluminum foil web → folded is made the netted explosion-suppressing material of type → rectangle lamination shape → cutting shaping → make netted blank → 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.
