Abstract

The invention discloses a production method for foamed aluminum. The method sequentially comprises the following steps of: feeding an aluminum ingot serving as a raw material into a foamed aluminum production line; placing the aluminum ingot into a heating crucible; heating and melting the aluminum ingot and pouring the molten aluminum ingot into a foaming box; adding a foaming agent into the foaming box for foaming; conveying the aluminum ingot out by using a conveyor belt after the foaming is finished; placing the foamed aluminum ingot on ground and naturally cooling the foamed aluminum ingot; cutting the cooled aluminum ingot into slices according to requirements of a customer; placing the sliced aluminum ingot on an oil press to compress by a certain height; cutting edges according to the specification of the customer; and packaging the aluminum slices to obtain the foamed aluminum. Because a porous structure is adopted, the foamed aluminum has semi-permanent sound-absorbing performance, is made of metallic material, fire-resistant completely and is completely free from hazard of noxious gases; the porous structure can effectively absorb energy and has a remarkable energy-absorbing effect in high-impact deformation rate; and the foamed aluminum does not have toxicity or smell or produce dust, peculiar smell or harmful substances to human body such as arsenic acid and the like and can be completely recycled and prepared from waste aluminum.

Description

A kind of foaming aluminium production technique and foamed aluminium and noise-reducing acoustic board
Technical field
The present invention relates to the foamed aluminum noise-reducing technology, aluminium production technique and foamed aluminium and noise-reducing acoustic board in particular foam.
Background technology
High speed along with track traffic, the caused vibratory noise of train operation can be more violent, and the high-speed rail transportation circuit will pass through many cities, its vibration and noise not only brings discomfort to passenger in the compartment, but also seriously disturb resident's along the line orthobiosis, even influence the normal operation of near school, scientific research institutions and hospital, bank etc.
The experience of external exploitation high-speed rail transportation shows: use the vibration and noise reducing product, fatigue, the abrasion that not only can alleviate vehicle, track, electric installation reduce maintenance cost, but also can reduce the influence of vibration and noise to resident along the line, buildings.Should actively use for reference external successful experience, research has the noise reduction technology of independent intellectual property right and develops relevant product energetically for this reason.
The vibration and noise reducing material not only will have good absorbing performance, also must safe, durable, easy construction, be convenient to maintenance, light weight, take up space less, also should possess performances such as fire-retardant in addition, cost is low, but does not have a kind of like this sound insulation and noise reduction material that can satisfy various requirement of appearance so far.
Summary of the invention
Technical problem to be solved by this invention is at the prior art deficiency, and a kind of foaming aluminium production technique and foamed aluminium and noise-reducing acoustic board are provided.
The present invention adopts following technical scheme:
A kind of foaming aluminium production process, may further comprise the steps successively: the raw material aluminium ingot--be sent on the foaming aluminium production line, put into the sweet pot of heating, heating and melting--pour in the foaming box, add the foaming of foaming Ji--foaming finishes the back to be sent by travelling belt, is put in the ground naturally cooling--the cooling back is according to the customer requirement dicing--cut sheet be placed on compress certain height on the oil press--according to client's specification requirement cut edge--packing--finish.
In the described production method, described whipping agent adopts titanium hydride.
A kind of foaming aluminium is characterized in that, described foaming aluminium density is 0.2-0.4g/cm 3
A kind of foamed aluminium aluminium noise-reducing acoustic board adopts tackiness agent to bind between described synergetic successively foaming aluminium lamination, honeycomb aluminium lamination and the solid aluminum flaggy.
Owing to have cellular structure after the foaming, have the semipermanent sound absorption qualities, all adopt metallic substance, 100% anti-combustion, completely without toxic gas danger, the cellular structure body can effectively absorb energy, has outstanding energy-absorbing effect in the HI high impact deformation rate; Nontoxic, tasteless, can not produce human harmful substances such as dust, peculiar smell, arsenic acid; Can 100% regeneration, and available waste and old aluminium manufacturing.
