Abstract
The utility model relates to a foam aluminum tube used for insulating sound and reducing noise. The technical problem to be settled is that the provided foam aluminum tube obtains the characteristics of compact structure, good sound insulation effect and convenient use. The technical solution is characterized in that: the foam aluminum tube is made of aluminum material; the aluminum is cylindrical; the tube wall of the aluminum tube is filled with many closed foam holes which are arranged in disorder; and insulation film which is obtained through cooling and solidifying the melted aluminum material is provided between the adjacent foam holes. The diameter of each foam hole is 2-6mm. The thickness of the tube wall is 3-15mm.
Description
Technical field
The utility model relates to a kind of sound insulation materials, especially the foam aluminum pipe made of porous crack aluminum material.
Background technology
Sound insulation and noise reduction is the important topic that modern society faces; Sound insulation and noise reduction is in traffic and transport field, building field, military field, manufacturing industry and aspect human health important effect is arranged all.Existing sound insulating panel as sound insulation and noise reduction is mainly the flat board that porous material is made, the defective of such sound insulating panel is to use and is limited in scope, need be when isolating some sound source with flat board cutting back splicing, institute takes up space bigger, and spliced soundproof effect is relatively poor, uses installation all not too convenient.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of foam aluminum pipe is provided, and this foam aluminum pipe should have volume compact, characteristics that soundproof effect is good, easy to use.
The technical scheme that the utility model provides is: the foam aluminum pipe, the employing aluminum material is made, it is characterized in that this aluminum pipe is a cylindrical shape, being full of the crafters of the closure of numerous lack of alignment in the tube wall of aluminum pipe, is the isolated film that described aluminum material fusing back cooled and solidified forms between the adjacent bubbles hole.
The aperture of described crafters is 2-6mm.
The thickness of described tube wall is 3-15mm.
The beneficial effects of the utility model are: because this foam aluminum pipe is a cylindrical shape, so can directly use, need not splicing when isolating some sound source; Be full of numerous bubbles in the tube wall of aluminum pipe, the scrambling of bubble and three-dimensionally make it possess good sound damping; Stretching into sound wave that the point sound source (as waste pipe) in the middle of the foam aluminum pipe goes out can be by diffuse reflection, and the phase mutual interference makes acoustic energy be converted into heat energy, thereby makes acoustic noise reducing; The foam aluminum pipe is compared with other sound insulation pipes, and the low frequency absorbent properties are good; Thereby have excellent absorption sound wave, reduce anti noise.Through architectural environment inspection center of Tsing-Hua University the foam aluminum pipe of 10mm thickness is detected, the average sound absorption coefficient of 200HZ-1600HZ is 0.53.Have the advantages that tangible volume is little, acoustically effective is good.In addition, this foamed pipe also has anti electromagnetic wave (wave frequency when 1GHZ, electromagnetic shielding amount can greater than 75Db), low heat conductivity (thermal conductivity be fine aluminium 1/60), heat resistance (under 780 ℃ of high temperature shape not can avalanche), density little (approximately be fine aluminium 1/5～1/10), can absorb impact energy, the characteristics of corrosion-resistant and handling ease (can cut, punch, crooked and bonding).
Description of drawings
Fig. 1 is the main TV structure schematic diagram of this foam aluminum pipe.
Fig. 2 is the left TV structure schematic diagram of this foam aluminum pipe.
The specific embodiment
As shown in the figure, this foam aluminum pipe 1 adopts aluminum material to make; Aluminum pipe is a cylindrical shape, and caliber size (size of internal diameter and external diameter) can be selected as requested; The thickness of tube wall also can be determined (generally being 3-15mm) as requested; Be full of the crafters 1-1 of the closure of numerous lack of alignment in the tube wall 2 of aluminum pipe, the isolated film between the adjacent bubbles hole is formed by described aluminum material fusing back cooled and solidified.
The manufacturing process of this foam aluminum pipe is: earlier aluminium is heated to high temperature (about 800 ℃) and makes it be molten into aluminium liquid, be incubated pouring in the incubator in the aluminium liquid then, and the adding blowing agent is stirred (mixing time 7-9 minute) again; Then the aluminium liquid of foamed state is poured into and treated in the mould that it takes out after cooled and solidified gradually; Adopt the mode of cutting and polishing to obtain required foam aluminum pipe at last.In the manufacture process, the pore size of crafters can be regulated by adjusting the mode that stirs; General crafters aperture of recommending to adopt is 2-6mm, and soundproof effect and mechanical strength all are in preferable states.
The cavernous tubing that the foam aluminum pipe is made up of bubble and aluminium barrier film; Its proportion is 1/20 of iron, is 1/4 of timber and plastics.The sound-absorbing characteristics of foam aluminum pipe are: sound can produce diffuse reflection in the foam aluminum pipe, and the phase mutual interference makes acoustic energy be converted into heat energy, thereby makes acoustic noise reducing.The foam aluminum pipe is compared with other sound insulation pipe, and low frequency absorption, shock resistance and fireproof performance are good.
