Problems solved by technology

This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself.
In addition, the current explosion-proof materials generally use mechanical cutting technology to cut slits on the metal foil, and then stretch it. The cutting waste and particles generated during cutting are unfavorable for the use of explosion-proof materials.

Embodiment 1

[0007] The zinc-copper alloy melted and cast ingot is rolled into a zinc-copper alloy foil with a thickness of 0.03 mm. The mass % of each element in the zinc-copper alloy foil is copper 62.0, nickel and cobalt 13.5, iron 0.5, manganese 0.3, silicon 0.15, arsenic , antimony, bismuth elements are not more than 0.002, the balance of zinc, the sum of impurities is not more than 0.9. The zinc-copper alloy foil is slit with a laser device, and stretched to form a mesh explosion-proof material. The cutting equipment used is a laser slitting machine, the power of the laser head of the slitting machine is 100 watts, and the cutting speed is 200mm / s. Stretch forming is operated by a stretching machine, and the stretched mesh is at an angle of 70-90 degrees to the original plane.

Embodiment 2

[0009] The operation of Example 1 was repeated, except that the mass % of certain elements was changed to copper 65.0, nickel and cobalt 16.5. The thickness of the zinc-copper alloy foil is modified to 0.02mm.

Embodiment 3

[0011] The operation of Example 1 was repeated, except that the mass % of certain elements was modified to copper 64.0, nickel and cobalt 14.5. The thickness of the zinc-copper alloy foil is modified to 0.08mm.

Abstract

The invention provides a zinc-copper alloy explosionproof material and a preparation method thereof. The explosionproof material is prepared by the following steps in turn: making zinc-copper alloy cast ingot; rolling zinc-copper alloy foil; cutting joints by a joint cutter; and drawing to form a meshy material. A zinc-copper alloy contains the following elements in percentage by mass: 62.0 to 65.0 percent of copper; 13.5 to 16.5 percent of nickel and cobalt, 0.5 percent of iron, 0.3 percent of manganese, 0.15 percent of silicon, less than or equal to 0.002 percent of arsenic, less than or equal to 0.002 percent of antimony, less than or equal to 0.002 percent of antimony, and the balance of zinc. The impurity content of the alloy is less than or equal to 0.9 percent. The zinc-copper alloy foil is 0.012 to 0.10 millimeter thick. The laser beam emitted by the joint cutter is almost vertical to the movement direction of titanium alloy foil; the total power of the laser lay emission is 100 to 1,000 watts; and 3 to 5 parallelly arranged laser ray emitting devices are used for joint cutting.

Description

technical field [0001] The invention relates to an explosion-proof material, especially a zinc-copper alloy explosion-proof material and a preparation method thereof. Background technique [0002] In the storage and transportation containers of flammable and explosive liquid and gaseous hazardous chemicals, in order to prevent the medium from burning and exploding due to accidents such as static electricity, open flames, gunshots, etc., it is necessary to fill a kind of mesh explosion-proof material in the storage and transportation containers. Material. Existing explosion-proof materials are made of aluminum alloy. This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself. In addition, the current explosion-proof materials are generally made by cutting slits on the metal foil by mechanical cutting technology, and then stretched. The cutting waste and particles generated during c...
