Description
Technical field
The present invention relates to abatvoix, be specifically related to a kind of pyrophillite environment-friendly 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; At abatvoix, be installed in the process on building wall, 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.
Agalmatolite Ores In China aboundresources, exploitation aspect major product is ceramic grade, refractory material level, glass level, engraving level, scale with abroad than less than normal, product specification is not high, deep processed product portion is few, thereby economic benefit is not good enough, the key overcoming the above problems is to strengthen the research and development of pyrophyllite deep processed product.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of pyrophillite environment-friendly foaming abatvoix is provided.
Pyrophillite environment-friendly foaming abatvoix is comprised of pyrophillite compound foaming agent and built-in frame, built-in frame is lain on mould, after short steel pipes in built-in frame inserts column, adopt pyrophillite compound foaming agent to be cast in built-in frame periphery, built-in frame is embedded in the inside of pyrophillite compound foaming agent completely, through standing curing processing, roasting and cooling after, be packaged as pyrophillite environment-friendly foaming abatvoix finished product.
Pyrophillite is the one of clay mineral, and ore, take bulk as main, also has earthy and fibrous, pyrophyllite normal with the mineral intergrowth such as quartz, kaolinite, montmorillonite, dickite, sericite and kyanite, andalusite, corundum; Pyrophillite slip fluidity is good, good penetrability, and pyrophillite has good heat stability and little hygral expansion, for this reason, can for the manufacture of size accurately, the product of Heat stability is good, body drying shrinks little, indeformable, burn till crack little, firing whiteness 90～96%, degree of fire resistance >=1700 ℃, insulation, thermal insulation is good, stable chemical performance, only has at high temperature and could be decomposed by sulfuric acid.
The concave convex rod potter's clay powder with air purification function is comprised of the sticky Concave-convex clay rod of height, attapulite constant humidity amendment, natural-minerals adsorptive filter medium, cacumen biotae, aluminium silicate fiber peacekeeping polyacrylamide; there is good caking property, plasticity, thixotropy, refractoriness and heat stability; the effectively hazardous substances such as formaldehyde, ammonia and benzene in absorbed air, protection of the environment and promote the healthy of people.
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.
Hydrogen peroxide is commonly called as hydrogen peroxide, and outward appearance is colourless transparent liquid, is a kind of strong oxidizer, and the present invention selects mass fraction >=35% of industrial hydrogen peroxide, after mixing, can generate a large amount of bubbles with the concave convex rod potter's clay powder with air purification function.
