Description
Technical field
The present invention relates to abatvoix, be specifically related to a kind of unburned serpentine boulder foaming abatvoix.
Background technology
City noise is having a strong impact on townsfolk's normal life and health of human body, city noise mainly refers to traffic noise, factory noise, construction noise pollution and noise of social activities, the influence basin of its noise and influence degree are day by day serious, on the impact of civic living environment greatly, become one of noticeable city environmental pollution problem.
Conventionally adopt damping material to produce the products such as some abatvoixs, noise barrier, sound-absorbing net and noise damper and control noise pollution, also having some damping materials is to produce the products such as abatvoix after processing by foaming, to improve the performance of product.
Abatvoix quality after sale foaming is in the market more crisp, and the bulk strength of abatvoix, counter-bending ability and result of use are undesirable; Be installed in the process on building wall at abatvoix, abatvoix needs on-the-spot 4 the above bolts hole that bore, not only time-consuming, increase difficulty of construction, and be easy to abatvoix be broken or shatter in when boring, after abatvoix is arranged on building wall, due to the effect of gravity, can cause the abatvoix fragmentation from building wall after boring to come off.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of unburned serpentine boulder foaming abatvoix is provided.
Unburned serpentine boulder foaming abatvoix is made up of serpentine boulder cement blowing agent and built-in frame, built-in frame is lain on mould, after short steel pipes in built-in frame inserts column, adopt serpentine boulder cement blowing agent to be cast in built-in frame periphery, built-in frame is embedded in the inside of serpentine boulder cement blowing agent completely, maintenance is carried out in conventional maintenance process according to cement products, is packaged as unburned serpentine boulder foaming abatvoix finished product.
That serpentine boulder has is heat-resisting, anticorrosive, wear-resisting, heat insulation, sound insulation and operational characteristic preferably, and block or fibrous serpentine boulder all can have gloss, block as wax, fibrous as thread.
Attapulgite has another name called palygorskite or Palygorskite, be a kind of layer of chain structure containing Shuifu County's zeopan clay mineral, attapulgite has unique layer chain structure feature, in its structure, has crystal lattice, therefore contain the Na of non-quantitative in crystal
+, Ca
2+, Fe
3+, Al
3+, crystal is needle-like, fibrous or fiber collection shape.Attapulgite has unique dispersion, high temperature resistant, the anti-good colloidal nature such as saline and alkaline and higher adsorption capacity, and has certain plasticity and adhesion stress.
The Concave-convex clay rod product of selling on market, there are respectively Concave-convex clay rod powder and the large series of high sticky Concave-convex clay rod powder two, viscosity≤the 1800mPas of Concave-convex clay rod powder, high sticky Concave-convex clay rod soil property exquisiteness, has oily soapy, light weight, property are crisp, fracture is conchoidal or irregular shape, and water imbibition is strong, tool viscosity and plasticity when wet, viscosity >=the 2200mPas of high sticky Concave-convex clay rod powder, is conducive to the bonding between raw material.
High sticky Concave-convex clay rod powder refers to gets 28.0g Concave-convex clay rod powder sample, add in the suspension cup of homogenizer, add again 372g water, suspension cup is placed on homogenizer, under the rotating speed of 11000 revs/min, stir 20 minutes, to pour in the beaker of 250mL through high-speed stirred sample suspension, use NDJ-1 type rotation viscometer carries out the viscosity of test suspension liquid, the Concave-convex clay rod powder of tested viscosity value >=2200 mPas again.
The pH value of Concave-convex clay rod raw ore is 8～9, need in the present invention to carry out acidification, acidified Concave-convex clay rod after treatment is activated attapulgite, the various performances of activated attapulgite all will be greatly improved, particularly strengthen the adsorption cleaning ability of concave convex rod, it is 5.5～7.5 that activated attapulgite pH value is controlled, water content≤2%.
