Description
Technical field
The invention belongs to ceramic, particularly a kind of tourmalinite matter integral honeycomb pottery.
Background technology
Tourmalinite is the general name of tourmalinite family mineral, is to be aluminium, sodium, iron, the magnesium of feature, the ring texture silicate minerals of lithium with the boracic, claims tourmaline again.Color is different different because of composition, and black, brown, redness and blue-greenish colour etc. are arranged.Because tourmalinite has unique heteropole symmetrical structure (typical case shows as pyroelectricity and piezoelectricity), it has a lot of functions and purposes:
The one, have the generation that excites negative aeroion.When tourmalinite contacted with air, the electric field action of tourmalinite was in airborne water molecules (electrolysis voltage of water molecules is 1.23 volts), and making it ionization becomes OH
-, OH
-Attract airborne water molecules to form OH
-(H
2O)
n, increase airborne negative ion concentration.Negative aeroion enters human body through respiratory system, and the system that can excite nerve produces good effect, improves blood circulation, promotes the metabolism of human body, adjusts blood pH, and active cells makes the people can keep abundant energy; Negative ion PARA FORMALDEHYDE PRILLS(91,95), benzene, the NO of tourmalinite generation simultaneously
XThe effect of clearing up is arranged, thereby effectively improve quality of air environment.Tourmalinite processing is pulverized more carefully, and its generation of static electricity must be more many, and voltage is more high.The electrostatic field that tourmalinite produces has adsorption to airborne charged particle, can adsorb dust, charged ion etc., purifies air.
The 2nd, it has functions such as far infrared radiation, as tourmalinite being attached on clothes and the bedclothes, then is conducive to the blood of human body circulation, also has the antibacterial antistatic function; Tourmalinite is invested in the water, and its far infrared radiation can make big water clusters resolve into little water clusters, realizes the activation of water, and increases the dissolved oxygen amount in the water.After the people drank this water, the easy permeation cell film of the water capacity increased cytoactive, improves the immunizing power of human body and animal.The function of this activated water of tourmalinite also has good action to the breed of aquatic products and fancy fishes;
The 3rd, tourmalinite touches water and just sparks, make water electrolysis become hydrogen ion and hydroxide ion, hydrogen ion is combined with the negative ion that tourmalinite sends and is neutralized, having become general hydrogen atom discharges, hydroxide ion then combines with water molecules, constantly produces the hydroxyl negative ion H that a kind of surface has active function
3O
2 -, the water of this process of process is owing to hydrionic minimizing has had weakly alkaline, and the reduction water hardness.Weakly alkaline water is highly profitable to HUMAN HEALTH, helps human acid-base balance and nutritive equilibrium; Water after tourmalinite is handled, to carry, store the pipeline of water, the metal device of water tank has passivation, prevent from getting rusty, fouling; Tourmalinite matter protective system has anticorrosion effectiveness to the hull of marine ship.Tourmalinite also helps the redox potential (OPR) that reduces tap water, has the effect that makes the water deoxidation.The redox potential of tap water is more low, shows that namely the oxygenate content in the water body is more few, belongs to reductive water, and water quality is more good; The redox potential of water is more high, easily causes recycle system illness.The tap water of China is extensive use of the chlorine disinfectant art breading now, and the redox potential of water is very high.Tourmalinite has the chlorine residue of removing in the tap water, reduces the effect of oxygenant.Tap water after tourmalinite is handled, its redox potential (OPR) reduces greatly, can drink for the people.
The 4th, tourmalinite comprises human body beneficial's trace element and mineral substance, and when water process tourmalinite, the tourmalinite slowly-releasing goes out trace element and the mineral substance that is received by human body easily as zinc, calcium, magnesium, gallium, strontium etc., makes human body obtain comprehensive, balanced nutrition.For example the country of the many lacks of water in the Middle East uses the sea water by distillation preparing fresh water, and this pure fresh water does not contain any beneficial element, must handle through tourmalinite, supply the trace element and mineral substance after, could supply to drink.
In addition, tourmalinite is at electromagnetic shielding, and also there is higher performance the aspects such as improvement of waste water and sewage, waste gas.As the water body that contains Victoria Green WPB is had good percent of decolourization, to containing Zn
2+, Cd
2+, Cu
2+, SO
4 2-Isoionic waste water, and ammonia nitrogen in the sewage etc. had Degradation.
In view of tourmalinite has so many advantage, it has begun to be applied to every field, but all has shortcoming and defect.For example, there is the people that tourmalinite is made powder, brushes at metope with coating, to produce negative ion, radiation infrared and shielding electromagnetism; Perhaps mix with the sizing agent of various organic or inorganics, the hydraulicity, air-setting, thermohardening wedding agent etc., spread upon the surface of various members again, with emitting far-infrared, negative ion, and water and gas are optimized processing etc., but there is not anti-erosion in it, and useful life longevity is poor, tourmaline intermediate layer easily comes off, and the specific surface area of unit volume is little, and treatment efficiency is low, the defective that the tourmalinite consumption is many; And for example, there is the people that tourmalinite is made Ceramic Balls, ceramic ring, pottery, enamel ware, is used for tap water, beverage, wine etc. are done optimization process, or in sauna, uses, to produce negative ion.Though this has solved the problem of useful life longevity, the problem that exist the specific surface area of unit volume little too, usefulness is low and the tourmalinite consumption is big; For another example, in order to improve the contact surface of tourmalinite and gas, liquid, people have developed tourmalinite matter porous ceramics (as porcelain filter) and tourmalinite foam ceramic again, but that they still have a fluid circulating resistance is big, and the energy consumption height, easily problem such as obstruction; The somebody has applied for that publication number CN101182234(application number is: 2007101684785) process patent, though can improve the tourmalinite service efficiency, but the muscle wall thickness that has following shortcoming: A, ceramic honey comb only has 0.1 ~ 0.3 ㎜, it itself is exactly a very thin thin layer, flood one deck tourmalinite slurry layer more in the above, make complex process, increase artificial and energy consumption, cause the cost height; B, because the problem of tourmalinite slurry fluidity, make ceramic honey comb when dipping tourmalinite slurry, the inconvenience red-tape operati, perhaps to be impregnated into the tourmalinite coating that forms behind the ceramic honey comb too thick for slurry, causes original very little through hole (generally being the size of 1 ~ 3 ㎜) to become narrower and small even stop up through hole; Perhaps soak inadequately, cause not soaking the tourmalinite slurry, perhaps soaked slurry but do not have effect or effect atomic because tourmaline intermediate layer is too thin.
Summary of the invention

The geometric parameters numerical table 1 of existing typical cellular pottery
| Via densities (cell/in 2) | 200 | 400 |
| Via area (mm 2) | 2.3 | 1.21 |
| The total port area % of cross section | 70 | 76 |
| Wall thickness (mm) | 0.28 | 0.15 |
| Specific surface area (㎡/m3) | 1890 | 2790 |
The present invention at first manages to make tourmalinite to increase as far as possible with the surface-area that liquid, gas contact, and tourmalinite will be more good to the treatment effect of gas, liquid like this; Secondly, consider that the tourmalinite goods have only one deck very thin on its surface to have an effect to gas, liquid, the effect from the tourmalinite performance away from of gas, liquid of goods inside is atomic, so tourmalinite is made the goods of thin-walled.Because it is big that ceramic honey comb has specific surface area, wall is thin, light weight and the high characteristics of physical strength, therefore tourmalinite is mixed in the ceramic batch, adopt ceramic honey comb preparation technology to make tourmalinite honeycomb ceramic goods, rely on the high-specific surface area of ceramic honey comb, the muscle wall thickness is the characteristics of 0.1～0.3mm only, under the muscle wall size that does not change existing ceramic honey comb and muscle wall thickness, tourmalinite is evenly distributed on the muscle pars intramuralis and surface of existing ceramic honey comb, both guaranteed that existing ceramic honey comb was long-pending higher than table, the characteristics that hole is big, again can ultimate attainment performance tourmalinite effect, significantly reduce the tourmalinite consumption simultaneously.
Tourmalinite is made ceramic, on the one hand can be by the process of ceramic post sintering, make the tourmalinite activation, strengthen the tourmalinite proper property, on the other hand, make ceramic by sintering, give the tourmalinite goods with higher mechanical properties, erosion-resisting characteristics and thermal stability, this is than directly brushing is much durable in use at the surfaces externally and internally of device or buildings the tourmalinite slurry.Because tourmalinite is surpassing (800 ~ 950 ℃ of certain temperatures, different and different with the tourmalinite raw material) time, can undergo phase transition and fusion, the tourmalinite performance is fallen sharply, thing and ultra tiny raw material (natural nano-material such as ball clay, wilkinite and synthetic nano material such as silicon sol etc.) so adding low temperature is fluxed, the two uses jointly, and acceleration of sintering effective can burn out intensity height, tourmalinite honeycomb ceramic that resistance to fouling is strong at 770 ℃ with interior.
The tourmalinite honeycomb ceramic that the present invention makes can provide the specific surface area of 1000～3000 ㎡/m3, tourmalinite is had contact with gas, liquid than big area; Again honeycomb ceramic body is made the micropore ceramics material, then gas, liquid can enter in the ceramic honey comb body wall, the tourmalinite of muscle pars intramuralis also can play a role like this, with the tourmalinite on ceramic honey comb muscle wall top layer, acts on gas, liquid from inside and outside two aspects.In addition, the microporosity of ceramic honey comb body wall also helps to strengthen the effect of the hazardous and noxious substances in adsorbed gas and the liquid, plays Degradation.
Described tourmalinite matter honeycomb article can be made different shape, is used for air outlet, electric fan, the vent fan of various conditioners, also can be installed in the special device, aims at the ceramic honey comb through hole with small fan and blows out negative ion and make airflow circulation; Also the tourmalinite honeycomb ceramic can be made circular, install additional with pipeline in, be used for the uninterrupted improvement of the continuous optimization process of tap water, various wine and waste water, sewage;
Described tourmaline honeycomb ceramics goods, also can be used for electromagnetic shielding, better than coming the sealed electromagnetic irradiation device with metal shell and being coated with the tourmalinite coating at the buildings surfaces externally and internally, because the honeycomb ceramic product that tourmalinite is made is in electromagnetic radiation shielding, can ventilation, daylighting, heat transfer etc.
Main performance index of the present invention is:
Axial compression strength (MPa) 〉=2.5, water-intake rate (%) 〉=25%,
Proportion (g/cm
3) 0.65 ~ 0.9, the total port area of cross section 〉=70%.
The present invention compares with existing tourmalinite goods, under the muscle wall size that does not change existing ceramic honey comb and muscle wall thickness, tourmalinite is evenly distributed on the muscle pars intramuralis and surface of existing ceramic honey comb, both guaranteed that existing ceramic honey comb was long-pending higher than table, the characteristics that hole is big, again can ultimate attainment performance tourmalinite effect, significantly reduce the tourmalinite consumption simultaneously, be embodied in: the one, the cellular tourmaline ceramic that the present invention prepares has very high use effect: because the aperture in each hole of honeycomb parallel channels 1-2mm only, work as gas, when liquid flow is passed through honeycomb, can all be cut into 1 ~ 3mm
2Or thinner air-flow or liquid stream, in electric field narrow, that formed by tourmalinite, being polarized continuously, storage effect strengthens gradually, and receives better treatment effect.Passage is more narrow more elongated, and then treatment effect is more good.And in contrast be, the electric field of formation such as irregular duct of the hole that tourmalinite ball and ring pile up to form, the micrometer grade hole of micropore ceramics, foamed ceramics then is instability and discrete, the hole equivalent diameter is bigger, the processing efficiency of convection cell is low.Far-infrared radiation also is like this: in narrow and small cross section, fluid is subjected to the radiation density of ceramic honey comb all directions bigger.In addition, tourmalinite matter Ceramic Balls is much bigger with the more all-in-one-piece honeycomb of fluid resistance that ring is piled up the hole that forms, the micrometer grade hole of micropore ceramics, the irregular duct of foamed ceramics etc., so use favose tourmalinite matter pottery, also can make the user obtain good energy-saving effect.The 2nd, aspect economic and social benefit, tourmalinite matter integral honeycomb pottery reduction effect is very remarkable, with 200 orders/inch

2/ m
3, the tourmalinite ball of Ф 10mm, its geometric proportion surface-area is 180m
2/ m
3About, the polarization efficiency of disregarding tourmalinite matter Ceramic Balls is lower than honeycombed tourmalinite matter pottery, and is only identical in the geometric proportion surface-area, almost wants 10 ~ 11m
3The tourmalinite ball, just can reach 1m
3The surface-area of honeycomb.Press tourmalinite ball bulk specific gravity 1.3-1.4T/m
3With tourmalinite volume 40%, generally to use 13 ~ 15 tons tourmalinite ball, close the tourmalinite of 4200～6000kg, just can reach 1m
3The water treatment effect of honeycomb.But the tourmalinite honeycomb ceramic, proportion 650～900kg/m
3, press tourmalinite volume 10 ~ 80%, preparation 1m
3The tourmalinite honeycomb ceramic only need tourmalinite 65 ~ 720kg, than the saving of sphere tens times tourmalinite consumption.In addition, burn till energy-conservation on, obvious effects is also arranged: under the equal firing temperature, make 1890m
2Surface-area, as long as cellular tourmaline ceramic takies about 1.2 ~ 1.3m
3The kiln volume, and spherical to take kiln position 11 ~ 13m
3About, under uniform temp, to burn till, tourmalinite honeycomb ceramic energy consumption is 1/10th of tourmalinite ball energy consumption.
