Description
Technical field
The present invention relates to waste diatomite and make the method for high function novel material, promptly, during the waste treatment of the waste diatomite of discharging at the filtration process of various manufacturing works etc., good operability, organic compositions such as the enzyme in the low and remaining control waste diatomite of dry fuel cost, yeast, make full use of its function etc., can obtain the method that H.D waste diatomite is made high function novel material with low cost, the invention still further relates to the high function novel material that obtains by the waste diatomite class and utilize diatomaceous composition for building material.
Background technology
In the filtration process of various manufacturing works such as brew-house or soy sauce factory, use diatomite as filter material always.For example, brew-house processes hops in the wort of barley, increases bitter taste or fragrance, makes its fermentation, utilizes diatomite that it is filtered, and makes beer.
Such diatomite, become the waste material (waste diatomite) of mud (the ヘ De ロ) shape that contains large quantity of moisture and yeast or vinasse after using, its waste treatment is pretty troublesome, normally bury processing, but contain a large amount of water owing to containing yeast and vinasse, therefore also must consider a large amount of water treatments and the processing of foul smell.In addition, even in cement kiln, carry out burning disposal,, also need to consume lot of energy owing to contain large quantity of moisture.
Therefore, recently people handle by drying, granulation, charing and 800～1000 ℃ high-temperature steam or carbon dioxide maintenance etc. in research, and waste diatomite is carried out activation treatment, inquire into to bury and handle and the utilization again of burning disposal waste diatomite in addition.
On the other hand, in the past because the environment of the rainy humidity in Asian Monsoon area, in Japan and Chinese, use mostly have the plaster that prevents the dewfall effect, structure materials such as soil, timber are as building materials such as walls.
But, in recent years,, adopt building materials more with weather resistance, noise reduction, stopping property, economy etc. along with high stratification, the densification of buildings, use with the material of construction of oil in a large number as raw material.
How wet but these are that the material of construction of raw material exists to lack and prevents dewfall with the oil, be not suitable for high temperature environment.
Thereby the research of the composition for building material that contains porous matter inorganic materials in the past comes into one's own.For example, in the Te Kaiping 8-49308 communique, disclose the resistivity against fire that has and contain the structure material same degree of mortar, weather resistance, thermotolerance, heat retaining property, deodorization, noise reduction, economy etc., also had the structure material that prevents the dewfall effect simultaneously concurrently.
This structure material is the composition for building material that contains cement classes such as mortar, white cement and burn till porous matter inorganic materials such as diatomite, mortar with respect to 100 weight parts, contain cement class 10～50 weight parts, burn till porous matter inorganic materials 30～120 weight parts such as diatomite, possess and the resistivity against fire that contains the material same degree of mortar, thermotolerance, thermal insulation etc., have the dewfall of preventing effect simultaneously.
That is, the material of this embodiment is, with respect to mortar, allocate into necessary amount the cement class, burn till porous matter inorganic materials such as diatomite, mix, in this mixture, add water, after mixing, floating with trowel on base plate, make sheet material class, panel class, wallboard etc.
In constructional method, the meaning floating with trowel is, applying compulsory pressure to mixing thing on base plate flattens it, if with the floating pressurization of trowel, sagging phenomenon in the operating process or adhering on working suit are fewer, and, residual hardly micro mist on the finished surface of dry back, also can take place hardly in addition micro mist towards periphery environment disperse, be attached to surrounding environment and people situation on one's body.
But, according to the cooperation of composition and non-pressurized coating operation, when promptly using hairbrush, application cylinder, spray gun etc. that ground is carried out precision work, the sagging phenomenon of generating material or attached on the working suit in the operating process, cause operation quality not good, and the quality of finished surface is also very poor.
And, residual micro mist on the finished surface of dry back, these disperse towards periphery, and the comfortableness aspect of life goes wrong.
In addition, nearest for some time, the situation that the user utilizes the surface of all foot couple sheet material, panel, wallboard etc. to construct increases, in this case, plus-pressure is not coated with operation often, promptly uses methods such as hairbrush, application cylinder, spray gun, therefore, if only use the floating pressurization of trowel, can not satisfy practical requirement.
In addition, contained in the caking agent for furniture or floor etc., be diffused into harmful chemicals such as airborne formaldehyde or gas etc. in recent years, it need be decomposed, removes.
On the other hand, not that used waste diatomite generally is to entrust the professional of refuse treatment to bury processing in the factory of new diatomite but food service industry etc., but owing to be the mud shape that contains organism such as microorganism, yeast, vinasse etc., the foul smelling smell, so intractable, because mouldy or perishable etc. various mal-conditions, so be to handle the professional also to wish a kind of rubbish of avoiding.Therefore, handling rises every year, has the problem that is threatening manufacturing cost.
In addition, by the utilization again of waste diatomite activation treatment, not only activation treatment is very complicated, but also needs pyroprocessing, cost great amount of manpower and material resources, and therefore also not having at present can practicability.
The present inventor, not only for making full use of new diatomaceous composition for building material, and to effective processing of aforesaid waste diatomite with effectively utilize and carried out deep research, handle simple, can turn to loose condition (of surface) by solid substance, can make the raw material that can preserve that does not produce mould, assorted bacterium, can reduce foul smell, shorten treatment process, reduce production costs, give full play to the effect of organic compositions such as the enzyme that contains in the waste diatomite, yeast, be suitable for multiple use, for example, the absorption capacity of decomposition of harmful chemicals such as formaldehyde is very good.From these angles, developed effective processing of brand-new waste diatomite.
On the other hand, the present invention also provides diatomaceous composition for building material, said composition not only has the advantage of prior art, it is weather resistance, noise reduction, resistivity against fire, thermotolerance, heat retaining property, deodorization, economy etc., even adopt hairbrush, the application cylinder, spray guns etc. do not apply the method for forced draught also can carry out non-pressurized coating on ground, basically the sagging phenomenon that does not have material in the operation, also be attached on the working suit hardly, and, residual hardly micro mist on the finished surface of dry back, also have further damping effect, prevent that the dewfall effect is better.

Embodiment
Below, based on the 1st embodiment, promptly the present invention is described in detail for the high function novel material of waste diatomite.
Prerequisite as the novel material method of filtering back depleted mud shape waste diatomite is, the drying efficiency of the mud shape diatomite treatment system of use fuel in the past is poor, energy expenditure increases, and owing to be the pyroprocessing system, promptly allow to recycle, its utility value also significantly reduces, and therefore, the drying means of use fuel in the past no longer adopts.
So, in novel material method of the present invention,, be to make full use of the bactericidal system that with the reaction heat of water, effectively utilizes alkali as the system that handles mud shape waste diatomite.Promptly, the cement minerals of to produce the unslaked lime (containing rhombspar) of high reaction heat with water reaction, selecting according to the kind of waste diatomite, produce subsidiary material such as the ferric oxide of heat and other gypsum, zeolite with air reaction and mixes, as drying treatment unslaked lime class use.
Then, one side utilizes organic compositions such as enzyme that this drying treatment possesses waste diatomite with the unslaked lime class, yeast to carry out remaining control, the water that mud shape waste diatomite contains is evaporated, removed to one side, utilizes alkali that the waste diatomite of mud shape is carried out sterilization, innoxious simultaneously.
In order to bring into play the function of these drying treatment with the unslaked lime class to greatest extent, the novel material system is divided into pretreatment process and formal two operations of treatment process.In pretreatment process, because the waste diatomite of mud shape or filter cake shape is easy and drying treatment is reacted with the unslaked lime class, unslaked lime and reaction of moisture produce high reaction heat (reaction heat of unslaked lime is 278Kcal/Kg), therefore, importantly, water content in the waste diatomite is controlled, extracted out moisture based on this control simultaneously.
Therefore, as pre-treatment, need utilize mixing machine etc. to waste diatomite fully stir, cradle, make waste diatomite aqueousization in heterogeneity.In general, aqueous diatomite is except planar water, and the moisture that contains in the pore is also a lot, and it is also very important to extract this moisture out.Press for contained moisture in this pore of abundant extraction in the method.
In addition, controlled contain moisture after, determine in subsequent handling should the blended drying treatment with the input amount of unslaked lime class.Determining and the input amount of the corresponding drying treatment of the amount of moisture of waste diatomite with the unslaked lime class, also is extremely important problem in the novel material of the present invention system.
Next, in formal treatment process, to finished broken, stirring through pretreatment process, fully squeezed out in the waste diatomite of moisture, blending and unslaked lime that can at a low price buy high with reaction heat is main raw and has suitably mixed the powdered mixture (drying treatment unslaked lime class) of subsidiary material such as cement minerals, ferric oxide, gypsum, zeolite and stir according to the kind of waste diatomite.
This drying treatment is considered expressed amount of moisture from waste diatomite with the amount of unslaked lime class, is the scope of the 10%-50% of waste diatomite in weight ratio.The short period of time that is stirred in about 5-10 minute ends up being suitable.After stirring end, leave standstill maintenance, preferred about 30 minutes of its time.In the maintenance processes, the waste diatomite temperature inside rises rapidly, and moisture becomes water vapour and scatters and disappears from the surface, and waste diatomite becomes loose dried powder.Form loose drying regime, meanwhile utilize alkali to carry out germicidal treatment.In this operation, for waste diatomite is dewatered expeditiously, dry, germicidal treatment, moisture squeeze out and curing time is extremely important factor.
Form waste diatomite loose, dried powder, innoxious with low cost regeneration, and have high function, therefore, it is added in the wall material of No. the 3358026th, patent that the applicant's ((strain) ワ Application ウ イ Le) holds, can significantly improve its quality and performance.Except the wall material, also have a lot of purposes, can be used as the raw material in a lot of fields such as building materials, anti-grass, insect protected, antibiotic ball, water-keeping material, light weight aggregate, roof greening plate, paddy rice usefulness fertilizer, soil improvement agent, daily necessities, according to the purposes renewable resources.In addition, by residual enzyme, yeast, also can play a role possessing H.D agricultural and field of food.
In a word, according to the present invention, when carrying out the waste treatment of waste diatomite, do not use fuel, but utilize the moisture that waste diatomite contains and the reaction heat of unslaked lime, with low cost waste diatomite is carried out drying treatment, utilize alkali to carry out sterilization, innoxious simultaneously, thereby make the raw material in a lot of fields such as building materials, anti-grass, insect protected, antibiotic ball, water-keeping material, light weight aggregate, roof greening plate, paddy rice usefulness fertilizer, soil improvement agent, daily necessities with low cost, according to the purposes renewable resources.
In addition, in main material unslaked lime, suitably add other subsidiary material, can carry out the drying treatment of waste diatomite expeditiously, make it multifunction according to the kind of waste diatomite.That is, the function that organic compositions such as the enzyme that contains in the remaining control waste diatomite, yeast have can be given full play to the effect of remaining enzyme, yeast etc., realizes multifunction.For example, absorption, the capacity of decomposition of harmful chemicals such as raising PARA FORMALDEHYDE PRILLS(91,95), additional high functionality.
Waste diatomite after the filtration soy sauce contains the salinity of 10-15%, the moisture of 50-60%, so its processing is very difficult.In the past, be that this waste diatomite is washed processing in food-processing factory, bury after the dehydration, but this practice cost height, also there is the problem of water treatment.This is the suitable example of material method of the present invention.
At first, in pretreatment process, the mixing tank that use can be controlled rotating speed stirred waste diatomite about 20 minutes, and the water that adheres on the diatomite and the moisture in the pore are squeezed out on the surface, added 30% specific surface area height (20000cm for example by weight
2/ g) light-burned calcium lime powder, stir about 5 minutes.Compacting then, about 30 minutes of maintenance.
The waste diatomite internal temperature is reaching after 30 minutes about 90 degree, and the waste diatomite of mud shape can be regenerated as the loose bio-diatomite again that can preserve.Stink also obviously reduces, and can utilize with diatomite as building materials.
In addition, determine through the analysis of Prefectura de Kanagawa industry synthetic study institute (16.5.24) that have the organism of an amount of remaining control in the fine porous of this waste diatomite, this organism plays a role, the absorption of formaldehyde, capacity of decomposition are very high.Below, represent its analytical results.
Sample is after 1 hour after 4 hours
(adding new diatomite)
Diatomite (ケ イ ソ ウ く ん) is below the following 0.02ppm of 0.11ppm
Tu Bicai
(adding this discarded diatomite)
Diatomite (ケ イ ソ ウ く ん)
Tu Bicai
Mix 10% (47g) and be almost 0 below the 0.005ppm
Mix 30% (47g) and be almost 0 below the 0.006ppm
This analytical results shows, be mixed with the diatomite (ケ イ ソ ウ く ん) of the dry waste diatomite of the contained organic composition of remaining control, compare with new product diatomite (ケ イ ソ ウ く ん) in the past, almost do not detect formaldehyde after 4 hours, showed high absorption, capacity of decomposition.
Formaldehyde absorption, capacity of decomposition have some to change with the physical adsorption degree of time of drying, thickness, condition of surface etc., but generally speaking formaldehyde absorption, capacity of decomposition are excellent.
Contain a lot of organism in the waste diatomite, for example,, have various organic compositions such as polyvalent alcohol, carboxylic acid, sulfonic acid, wherein contain a large amount of N (nitrogen) in the zymic occasion.This NH
2(amino) makes formaldehyde (HCHO) methylolation, becomes other materials.In addition, because formaldehyde and urea (urea) are reactive good, therefore become harmless with urea (urea) reaction.
Like this, the organic composition by containing in the control waste diatomite makes it residual, under the situation of this example, can make effective novel material of gas adsorption, capacity of decomposition excellence.
Wherein, the test method of testing above-mentioned formaldehyde minimizing is that sample (is coated with on the sheet glass and pays a dry thing, thickness: 4mm, area: 150cm
2) (air of formaldehyde allotment after decompression in the container, is enclosed in the substantial middle position of vacuum drier/12L) to be placed on Glass Containers.Leave standstill certain hour, the air in the collection container is measured concentration in the gas.The exposure condition of formaldehyde is that initial stage concentration 2.5ppm carries out for 50% time in 20 ℃ of temperature, humidity.
Below, based on the 2nd embodiment diatomaceous composition for building material is described.
As everyone knows, Powdered slaked lime is to add the material that water cure obtains in the unslaked lime that obtains in that shellfishes such as limestone or oyster are fired at 900～1200 ℃, and it is Powdered to be white in color.In the present invention, can use, in this composition for building material, when being applied to them on sheet material, panel, the wallboard etc., play a role as inhaling putting material and hardened material to plaster with the various slaked limes of slaked lime as representative.In the present invention, be 100 weight parts with it, by top other compositions of described cooperation.
Because white cement (portland cement) has the function as hardened material, therefore, with respect to the Powdered slaked lime of 100 weight parts, mixes preferred 88 weight parts with the scope of 80～90 weight parts.
In diatomite, the dewfall effect that prevents of burning till white diatomite is good especially.Being organized in when humidity is higher in the building space of its porous matter in porous organization, when humidity in the building space is low, is discharged into moisture moisture absorption in the space from porous matter tissue, plays the effect that the optimum humidity environment is provided.With respect to the Powdered slaked lime of 100 weight parts, cooperate 50～60 weight parts, preferred 55 weight parts.
Like this, in the present invention, the function separately of utilize above-mentioned Powdered slaked lime, white cement, burning till white diatomite, the ratio that their cooperate is, with respect to the Powdered slaked lime of 100 weight parts, and white cement 80～90 weight parts, Powdered white diatomite 50～60 weight parts that burn till, the composition for building material that forms in such ratio when the top ceiling of living space or wall are constructed, confirms that the humidity in room maintains about 50～60%.
Secondly, in the present invention importantly, use Powdered cement raw material.Clayey raw material described here is meant by mineral particles to constitute, present when adding water plastic material.Therefore, main component is a clay mineral, but also can contain some non-clay minerals.
Preferentially selecting the sepiolite powder of crystalline clay mineral, double-stranded shape structure for use, also can be wilkinite.
In above-mentioned bentonitic occasion, principal constituent not only comprises the montmorillonite as clay mineral, also contains as the quartz of silica mineral or the cristobalite of particulate.In addition, can also be the good zeolite of germ resistance.
This powder clayey raw material of range fit with 11～67 weight parts.About this cooperation, the inventor has carried out several trials.
Promptly, Powdered slaked lime with respect to 100 weight parts, add white cement 80～90 weight parts, Powdered white diatomite 50～60 weight parts that burn till, Powdered acrylic resin as auxiliary agent, Mai Telezi (メ ト ロ one ズ), each trace of defoamer and hemp cut 3 weight parts, add the powder clayey raw material, if its gross weight is 1 (the composition for building material overall weight is 1), under the condition that adds 1.3 times of water, to sepiolite (clear and mining industry Co., Ltd. system: trade(brand)name ミ Le コ Application) be respectively below 10 weight parts as above-mentioned clayey raw material, the scope of 11～67 weight parts, the above various cooperations of 68 weight parts are tested, when 10 weight parts are following, use hairbrush, during the coating of application cylinder, serious sagging is arranged.
It is generally acknowledged that sepiolite is a clay matter, the viscosity that its content produces more at most is big more, uses hairbrush, does not produce sagging when the application cylinder carries out application, but still have sagging when cooperating 68 weight parts above.Do not have sagging fully when cooperating 45 weight part to 55 weight parts, thereby be preferred.
Not mixing hemp cut, is 1 with the gross weight of composition for building, when sneaking into 1.2 times of water, also is roughly the same proportioning.And establishing the composition for building material gross weight is 1, adds 0.7～1.0 times of water, when spraying on the ground, if the ratio of above-mentioned sepiolite powder does not produce sagging equally in the scope of 11～67 weight parts.
When testing, obtained same result for wilkinite.So, confirm sepiolite, below the bentonitic particle diameter 0.5mm, preferred 0.2mm.
The result, the present invention is owing to contain Powdered slaked lime, the Powdered white diatomite that burns till, thereby has weather resistance equally with product in the past, noise reduction, resistivity against fire, thermotolerance, heat retaining property, deodorization, germ resistance, economy etc., with respect to 100 weight part powder slaked limes, contain white cement 80～90 weight parts, Powdered white diatomite 50～60 weight parts that burn till, because these cooperations and the Powdered porous matter tissue that burns till white diatomite, bring into play the damping effect better, effectively prevented the dewfall effect, and, owing to contain the Powdered clayey raw material of 11～67 weight parts, utilize its viscosity, even adopt hairbrush, cylinder, the spray gun application can not produce sagging yet in painting operation.
Promptly, these application modes are not exerted pressure for the application surface, so do not need the skilled person, be fit to the non-specialised staff and on surfaces such as sheet material, panel, wallboard, form surfacing in off hours at weekend, adopt coating process of the present invention not produce sagging, painting operation is easy, and can form the upper layer with good deodorizing and damping effect.In addition, almost there is not residual white micro mist and the micro mist environment phenomenon of dispersing towards periphery on the upper layer.
In addition, in the present invention, can cooperate Powdered acrylic resin by trace.This is when being applied to the mixing thing of the water of composition for building material of the present invention on the ground and the cementability of ground, preferably cooperates with 6～7 weight parts.
In addition, when cooperating Mai Telezi (メ ト ロ one ズ), be the function that prevents surface crack in order to have a mind to slow down mummification in painting operation during high humidity in summer, to improve and to the tack of hairbrush, cylinder, preferably cooperate 4～6 weight parts.
Cooperating defoamer, is the bubble that produces on application face when eliminating hairbrush, cylinder, spraying, preferably cooperates 1～2 weight part.
The upper layer that uses composition for building material of the present invention to form is white color tone, if cooperate the seasoning diatomite of 12 weight parts then present the color of grey colour system, if cooperate the red diatomaceous words of 12 weight parts then present redness, if cooperate 5～6 weight part Chinese loesses then can increase yellow.Below all be to utilize the colour developing of nature grogs, so the phenomenon of fading hardly.
Have, composition for building of the present invention is to be main component with porous matter inorganic mineral again, so can adsorb, decompose deleterious materials such as the formaldehyde that is diffused in the room air or gas etc.Because the pigment in the coating has adopted titanium oxide, this titanium oxide contacts with air and becomes titanium dioxide, by the redox reaction effect of photocatalyst brute force, can expect that it has certain decomposition effect to the harmful pollutants in the atmosphere.
In the past, the relation about titanium dioxide and photocatalyst once had following argumentation.Promptly, under photosynthetic situation, be to be catalyzer with chlorophyll, utilize luminous energy by water and carbon dioxide generating oxygen, and under the situation of photocatalyst, be with titanium dioxide photocatalyst semiconductor alloys such as (TIO2) as catalyzer, utilize luminous energy (ultraviolet ray), make active oxygen (O2 by airborne water (H2O) and oxygen (O2)
-), free radical (
OH) negative ion.
People know that active oxygen has very strong oxidation capacity, thereby can decompose, remove objectionable impuritiess such as the organic compound that becomes the dirt reason or bacterium or foul smell etc.Therefore materials such as the dirt that is decomposed also can be called the effect with automatic cleaning by flushings such as rainwater.
In a word, the redox reaction of photocatalyst will be as the oxynitride (NO of harmful pollutants in the atmosphere
X) or oxysulfide (SO
X) decompose, play the effect of purifying ambient air, also have the example of the soundproof fence of introducing motorway in order to improve environment etc.
With the mixing thing of titanium dioxide, as titanium dioxide: the part by weight of pottery such as follows.Titanium dioxide: pottery=5～40: 60～95, preferred 10～30: 70～90.When titanium dioxide is less than 5 weight %, can not bring into play its effect sometimes, when surpassing 40 weight %, effect does not have difference, and therefore the value about 40 weight % suits.
Wherein, during by the following stated compounding aid, Powdered acryloid 6～7 weight parts that contain the cementability of promotion and ground, thereby during formation and water mixing, guaranteed good bonding with ground, simultaneously, owing to contain water-soluble nonionic cellulose ester 4～6 weight parts as the water-retentivity thickening material, mummification so can have a mind to slow down in the painting operation, prevent surface crack, and, owing to contain defoamer 1～2 weight part, so even application face can not produce bubble yet when non-pressurized hairbrush, cylinder, spraying.
And, because the application surface do not have white powder residual, have not the advantage that environment towards periphery disperses.In addition, also has the outstanding advantage of deodorization.
