Description
Technical field
The present invention relates to abatvoix, be specifically related to a kind of unburned red mud foaming abatvoix.
Background technology
City noise drastically influence orthobiosis and the health of human body of urbanite, city noise is primarily referred to as traffic noise, factory noise, construction noise pollution and noise of social activities, its effect of noise scope and influence degree are day by day serious, on civic living environment impact greatly, one of noticeable city environmental pollution problem is become.
Generally adopting sound-absorbing material to produce the products such as some abatvoixs, soundproof wall, sound-absorbing net and deafener to control sound pollution, also having some sound-absorbing materials is produce the products such as abatvoix by foaming after being processed, to improve the performance of product.
Selling the abatvoix quality after foaming in the market more crisp, the bulk strength of abatvoix, bending resistance and result of use are undesirable; It is installed in the process on building wall at abatvoix, abatvoix needs the bolt hole that scene bores more than 4, not only time-consuming, increase difficulty of construction, and be easy to when boring and abatvoix is broken or shatter, after abatvoix is arranged on building wall, due to the effect of gravity, the abatvoix after boring can be caused to crush from building wall and to come off.
Red mud is that aluminium industry extracts the contaminative waste residue of discharge during aluminium oxide, and average often produces 1 ton of aluminium oxide, incidentally produces 1.0～2.0 tons of red muds. The pH value of red mud is 10～12, and China is as big alumina producing state of the world the 4th, and the red mud of annual discharge is up to millions of tons. Substantial amounts of red mud can not sufficiently effective utilize, large-area stockyard can only be relied on to stack, occupy a large amount of soil, the production of the mankind, life are caused many-sided impact directly or indirectly by the generation of red mud, so reducing yield and the harm of red mud to greatest extent, it is achieved by all kinds of means, the resource of big quantity extremely urgent.
Summary of the invention
It is an object of the invention to overcome weak point in prior art, it is provided that a kind of unburned red mud foaming abatvoix.
Unburned red mud foaming abatvoix is made up of cement made from red mud foaming agent and built-in frame, built-in frame is lain on mould, after short steel pipes in built-in frame inserts column, cement made from red mud foaming agent is adopted to be cast in built-in frame periphery, built-in frame is embedded in the inside of cement made from red mud foaming agent completely, carry out maintenance according to the conventional maintenance process of cement products, be packaged as unburned red mud foaming abatvoix finished product.
After the acidified process of red mud, red mud pH value controls 5.5～8.0, it is possible to improves the utilization rate of red mud, turns waste into wealth.
Attapulgite has another name called Paligorskite or Palygorskite, be a kind of layer of chain structure containing Shuifu County's zeopan clay mineral, attapulgite has the layer chain structure feature of uniqueness, there is crystal lattice in its structure, therefore containing variable amount of Na+, Ca2+, Fe3+, Al3+ in crystal, crystal is needle-like, fibrous or fiber collection shape. Attapulgite has the dispersion of uniqueness, good colloidal nature and the higher absorbability such as saline and alkaline high temperature resistant, anti-, and has certain plasticity and cohesive force.
