Abstract

PURPOSE:To obtain a compound material with high efficiency by charging >= one kind of material among a liquid-contg. solid, solution and liquid in a vessel, and impregnating liquid into the solid material by repeating pressure change by the change of atmospheric pressure plural times, or liberating liquid from the solid material or solution. CONSTITUTION:The degree of vacuum is held at a fixed value by opening a valve 14 automatically when the degree of vacuum exceeds a predetermined value, and by closing the valve automatically when the degree of vacuum is insufficient. After repeating plural times the evacuation and restoration of pressure, the pressure inside of a vessel is returned to the normal pressure by opening the valve 14 and stopping the operation of a vacuum suction device, and a solid material, etc. is taken out after opening a cover 8 for a discharging port. When liquid is intended to be taken out of a solid material or a solution, a valve 11 of an air introducing pipe 12 is opened and a valve 14 of an air introducing pipe 13 is closed and the vacuum suction device is operated. Thus, vaporization of the liquid is prompted by forming a stream of external atmosphere in the vessel 1 and the liquid may be taken out by the vaporization.

The present invention relates to a method for producing a foam.

As will be described in detail below with reference to the accompanying drawings, the solid matter referred to in this invention refers to sand, blast furnace slag, lime, gravel, marble, terrazzo, wood, clothing, etc., and the liquid-containing solid matter includes: Refers to the above-mentioned solids that contain liquids such as water and oil. Also, when simply referring to a solid substance, it also includes a solid substance containing liquid, and when simply referring to a liquid, it also includes a solution.Also, the container is not limited to a mixer, and there are cases where no crosstalk is required; The 7 rows of mixers will be explained when necessary. Figure 1 shows the 7 rows of mixers, 1 is a container with an input port 2 on the top and a discharge port 3 on the FtflS, 4
4g1 is a stirring shaft rotatably attached to the container 1, 5 is a stirring blade attached to the stirring shaft 4, 6 is an inlet opening/closing lid attached to the top of the container 41 so as to be freely openable, and 7 is an inlet opening/closing lid. 6
ff, 8 is a discharge port opening/closing lid attached to the bottom of the container 1 so as to be openable and closable, 9 is a sealing material attached to the top surface of the discharge port opening/closing lid 8, and 10 is a sealing material attached to the top of the container 1. An empty suction tube 12 is connected to a vacuum suction device (not shown) which is provided in communication with the container 11C, and 12 is an air introduction tube provided with the pulp 11 and communicated with the container 11C. .

K, who performs high-quality pressure transformation processing using the above-mentioned mixer, first closes the discharge port opening/closing lid 8 and the pulp 11 of the air introduction pipe 12, and operates a prime mover such as a motor (not shown) to rotate the rotating shaft 4. Rotate.

Next, the inlet opening/closing lid 6 is opened, and when a liquid-containing solid, a solution, and/or two or more of a solid and a liquid are poured into the container 1, these are stirred (5).

Next, when the inlet opening/closing lid 6 is closed and a vacuum suction device (not shown) is activated, the air in the chamber 41 is removed from the four empty suction tubes 10.
When the pulp 14 of the air introduction pipe 13 branched to the JE air suction pipe 10 is opened, outside air flows from the air introduction pipe 13 and the pressure inside the volume 61 is restored. If the opening/closing speed of the pulp 14 is set to the automatic side, not only can decompression and pressure return be performed slowly and quickly, but also the pulp 14 will be automatically opened when the predetermined degree of decompression is exceeded, and the degree of decompression will not be destroyed. If you automatically control it so that it closes when you open it, you can maintain a constant level of decompression. After repeating decompression and repressurization 4 times, open the pulp 14 and open the JX air suction system l' Stop the liquid flow and return the inside of the container to normal pressure,
Open the discharge port opening/closing lid 8 to take out the solids, etc., but when taking out the solids or the liquid from the 4 liquids, air introduction-ff12
Open the pulp 11 and open the valve 14ft of the air introduction pipe 13.
Close it! Suction device
It is also possible to make ltt to accelerate the vaporization of tL pieces and take out the liquid by vaporization, but in this case, it is more effective to do it during crosstalk.Also, there is a filter at the bottom for liquid discharge f1.
The pulp 16 can also be opened to drain and take out the liquid. If it is possible to install a compressor in the same volume 61 and link it with the TC air suction device, and change the pressure by alternately depressurizing and pressurizing 4 times, it is possible to use the air suction pipe instead of the air suction device. It would also be possible to change the pressure by connecting compressor 10 to compressor 10 and pressurizing and returning pressure. Then, during pressurization, pulp 11 of air inlet pipe 12 is opened to allow the outside air flow from the compressor to air inlet pipe 12. It is also possible to remove the liquid by discharging the liquid from the liquid discharge pipe 15 and using the Toki Konog V7ner to remove the liquid from the inside of the float 41. can be pressurized and quickly discharged and taken out.

The mixer/(P4 has been explained above, but the above mixer will be referred to as IA, and the one from which stirring devices such as the stirring shaft and stirring blades have been removed will be referred to as container B, and the following will explain the embodiment of the variable pressure treatment method for substances. do.

In addition, when changing pressure, the pressure is restored after pressure reduction to normal pressure.The pressure reduction is 6.
The pressure was changed to θOymHg by 51!121 in 7 minutes. In addition, when the original pressure is restored to normal pressure, the pressure is increased to lθ atmosphere, the pressure is changed to 3tgI in 7 minutes, and the pressure is reduced to fl.
For 4j with k7FD pressure, the pressure was reduced to 600 Hg%/
Although the pressure was increased to θ atmospheric pressure and the pressure transformation was repeated three times in 7 minutes, it is possible to change the degree of depressurization, degree of pressurization, speed of transformation, and number of transformations depending on the material, use, purpose, etc. of the solid material. Needless to say.

Example: Water repellent, silica sol, synthetic resin emulsion (W) and marble were placed in container B, and the pressure was changed by atmospheric pressure several times to bring it to normal pressure, then the marble was taken out and dried to produce marble with excellent water impermeability. I got it.

Example: Water repellent, Miricasol, synthetic resin emulsion, dye, and wood were placed in container B, and the pressure was changed several times using atmospheric pressure. After reaching normal pressure, the wood was taken out and dried to make it water resistant and flammable. Excellent and stained wood.

Implementation row 3 Put the water-bathable slag, water, and slow-cooled slag into a container WA, and repeat pressure change using atmospheric pressure several times while stirring to bring the pressure to normal pressure, then take out the slow-cooled slag (-1) to dry and use as a slow-release fertilizer. I have explained the above implementation and 7 rows, but impregnating a solid with a liquid (per C, the liquid includes water, dye, penetrating surfactant, termiticide, preservative, insect repellent, and mold repellent). , insecticide, water repellent, 717 Kasol, synthetic resin emulsion g], latex,
It is possible to use oils, fragrances, fertilizers, lubricants, A family, pigments, and/or two or more of them.For solid toads, sand, gravel, blast furnace slag, artificially selected aggregate, stone, and concrete can be used. -Leet,
Inorganic materials such as terrazzo, ceramics, porous metals, etc., and organic materials such as wood, plants such as hay, and synthetic resins can be used. Organic materials are given flame retardancy, water repellency, antiseptic properties, etc., inorganic materials are given impregnated properties such as waterproofness and water repellency, and products impregnated with fragrances or PP family are Custom made impregnations last. It goes without saying that a curing agent may be placed in the impregnated material and then hardened, and the impregnating liquid may be a molten material such as a bath-melted metal, a bath-melted synthetic resin, or a 4-melted barrier 7. It's not even up to 5. If the solid material is removed from the container and left to stand or cooled, the impregnated material will harden and the properties of the impregnated material will be imparted to the solid material. For example, ceramics impregnated with metals share the properties of metals and ceramics. Furthermore, when a solid substance and an impregnated substance react, such as silicic acid and molten aluminum, it has the characteristics of the reactant. Furthermore, when impregnating a solid substance with a molten substance, it is desirable to heat the solid substance to the same temperature or higher as that of the molten substance. 4A and stir it, repeat the pressure change several times during stirring to elute the salt in the sea sand into the water, and open the pulp of the liquid discharge pipe 15 to discharge the salt-containing water. The discharge port opening/closing lid 8 was opened several times to take out the sand from which the salt had been removed.

Deterioration of concrete made from sea sand has become a problem, but salt has seeped into the sand over the years, making it difficult to remove it by simply washing it with water. In addition, although depressurized and transgressive depressurization was performed seven times for seven minutes, water permeation into the sand was insufficient and only a small amount of salt was removed. However, by repeating depressurization and repressurization for 5 minutes in 7 minutes, the water penetrated deep into the sea sand and was able to sufficiently remove the salt. When using Container A, it can be used as a mixer to make mortar or concrete, so drain water containing salt from the liquid discharge pipe, add cement, or add aggregate, etc., or add the missing water. It can be mixed to make mortar and concrete. In addition, if you add enough water-containing sand cement to absorb the water in the sand and then add the missing amount of cement or coarse aggregate and the missing amount of water, the cement added first will absorb the excess water from the sand. The sand absorbs water to the extent that water does not ooze out (wet sand and rx Q), producing high-quality, strong mortar and concrete without causing plucking.

It should be noted that solid materials containing water-disintegrable substances are not limited to sea sand, and have never been applicable to sand contained in industrial wastewater or sewage. Furthermore, the solid material is not limited to sand.

Example S Pieces obtained by crushing pine roots into small pieces and alcohol are placed in a container AK and stirred. During stirring, the pressure change is repeated several times to dissolve the resin in the pieces into the alcohol, and the alcohol solution containing the resin is taken out. , separate the alcohol and resin and make the resin 4
Na.

In the above example, pine was used as the solid material and alcohol was used as the solvent, but the solid material is not limited to pine, and the solvent is not limited to alcohol, but solid matter from a pond or a solvent can be used. Also, when alcohol is used as a solvent, if the eluted components of the solid substance are edible or medicinal, they can be used as raw materials for medicinal liquors and health liquors.

As described above, when a solvent is used in a liquid, various useful components can be dissolved and extracted.

Incidentally, in this Example and Example 5, there is no case in which heating may be used in combination to promote elution.

Example 6 Dirty clothes, water and detergent were placed in a container aB, the pressure was changed to mg several times, and after the pressure was returned to normal pressure, the clean clothes could be taken out.

In the above-mentioned practical series, it is more effective to create a liquid flow inside the container, and it is effective for cleaning not only clothes but also dirty machine parts.

Actual power column 7 Porous metal, water and thermosetting cement container AK container,
The pressure change was repeated several times while kneading, and after returning to room temperature, the porous anchor metal impregnated with the thermosetting cement and water was taken out, and the thermosetting cement was hardened in a separate route.

In this implementation, the solid material and thermosetting material are not limited to those in the example, but if enclosed, aerated concrete is used for the solid material, thermosetting resin is used for the thermosetting material, and thermosetting resin is used for the aerated concrete. The thermosetting resin can be cured by impregnating the resin (including a curing agent) at room temperature or by heating.

Example g A foaming liquid was prepared by diluting a foaming agent with water, and the foaming liquid and cement were placed in container A and mixed while changing the pressure several times and returning to normal pressure. Add the foam made from the above foaming liquid to a volume of 4 AK and knead without changing the pressure. After foaming the cement paste, take it out from the container A.
It was cured to obtain cellular cement.

In the above-mentioned actual column, initially the container AK sand and foaming liquid are put in, and while kneading, the pressure is changed several times, then the pressure is returned to normal pressure, and more cement is added, and the pressure is changed several times, but the pressure is not changed. Na(
After kneading and adding foam that has been returned to normal pressure, it is possible to
The mixture may be kneaded to foam the mortar, which is then taken out and hardened. In addition, initially, the foaming injection liquid, cement, clay aggregate, and coarse aggregate were mixed in a volume of 6 hours, and the pressure was changed several times during mixing, and after returning to normal pressure, the foam was added and mixed again. It is also possible to knead without deforming the pressure, foam the concrete, take it out, and harden it. In addition, initially, cement and fine aggregate or coarse aggregate were placed in a floater AK and kneaded dry, then a foaming liquid was added and kneaded, and during the kneading, the pressure was changed once after multiple failures, and then the pressure was restored to normal pressure. It is also possible to add foam to the mixture, knead it without changing the pressure to incorporate foam, and then take it out and harden it. The above method for producing the foam-containing material is based on pre-7 ohm/glue removal, but it also contains cement and water or even aggregate. The pressure may be changed several times while kneading in A, and after returning to normal pressure, foam or a foaming liquid may be added and kneaded, the mixture may be foamed, and then taken out and cured. jI Place the initial foaming liquid and cement or aggregate (aggregate) in g vessel A, knead it, repeat the transformation of pressure while kneading it, return to normal pressure, knead it, take it out and let it harden. Good. In addition, when the aggregate is lime and silica sand, it may be initially hardened with cement and then cured in an auto cup. In addition, other water-added materials such as gypsum may be used instead of cement. It goes without saying that you can use more than one foaming agent to produce a foam-containing material. (After changing the pressure several times and returning to normal pressure, kneading it with a foaming agent 1), take it out from the container, put it in a mold, and foam it, and then cure it in an autoclave to make a foam-containing material.

Also, replace the opening/closing valve of the discharge port opening/closing lid of capacity 4A, and replace the opening/closing valve with F.
If you install the K Screw IJ and complete fine feed device, it is possible to knead and transform the pressure of the materials in container A with the on-off valve closed, and after mixing, open the on-off valve and transfer the screw set. By activating the conveying device or by pressurizing the inside of container A using a buzzing tuner, it is possible to convey the mixed wire. Also, by detecting the torque value of 1 g and 1 rotating shaft, it is slapped (directly). In terms of conversion, when the slump value is larger than the desired slump value, an outside air flow can be created in the container A to promote vaporization and make the slump value the desired slump value. When it is small, add 8 mouthfuls of water or foaming liquid to create the desired slang warmth.
These can be automatically controlled to set the slump value to a desired slump value. The above-mentioned slump DII removal can be used for mixing mortar or concrete before adding bubbles, and can be used as an independent method instead of detecting the torque value of the rotating shaft. A solid rotating rod may be placed in mortar or the like, and the rotational friction resistance value of the rod may be converted to the value of Keslump 11K.

This method can be used to measure the slump value during the mixed conveyance of a rotary fresh concrete tortoise, or during r-kneading stop and +h. When the transformer pressure is applied four times aa during the process, water penetrates deep into the aggregate and becomes water aggregate, and the alkali content of the cement is eluted, increasing the adhesive function of the cement and reducing the slump value. Not only that, but the strength is greatly improved even with a single straight knob compared to one that is not subjected to pressure transformation treatment.In addition, short-time cross-contact leads to the same effects as long-time cross-contact.The above effect is due to the fact that the This is due to the fact that water is effectively utilized for the initial aqueous phase reaction of the cement, that the bonding capacity of the cement is increased during the short WP, and that 1%9 is performed better. A of foam-containing material
The method is to use the above-mentioned method to create foam for foam-containing materials, and in the case of pre-7 ohm/glue removal, the cement or aggregate contains water in the light, so the molding process is small. Even if the foam is mixed in size, it is possible to produce a foam-containing material with low defoaming and high strength with a low water-to-cement ratio. In addition, although aggregates are very water resistant, it is desirable that the condition is such that water does not seep out, so there is a risk of multiple pressure transformations @ burying, and finally, when returning to normal pressure from a depressurized state, it should be done slowly. It is desirable to restore the pressure over time and reduce the amount of excess water being absorbed. I'll give you C. Therefore, the pressure may not be limited to 10 atm, but may be much higher. However, cement gluing machine iU
In order to increase the amount, reduced pressure treatment is preferable, and using 1# of reduced pressure and Caro pressure is considered to be ideal. In addition, when the pressure changing process is performed fjia times during kneading in step 5, the slump value becomes incredibly small compared to the case where the pressure changing process is not performed. The above indicates that the material that has been subjected to multiple pressure transformation treatments is suitable as a material for secondary concrete products made by hardening, such as concrete blocks, interlock blocks, and revetment blocks.

In addition, if a foaming agent mixed with a water reducer or a thickener is used for a period of time in the foaming world djif and injection agent, the foam-containing material will crack and break down. In addition, when silicic acid sol and synthetic resin emulsion are mixed with a water reducing agent and mixed with mortar or concrete, the strength of cracking increases. +Hura emulsif) and foaming surfactant or... are further mixed with water reduction or and thickener as AE agent +Ii! It is used to entrain air bubbles into mortar or concrete without causing bubbles, and also increases strength by creating cracks.
do. Also a foaming agent or top ik! When a skin additive is used, 4, and when Fryal or pozzolan is added to semenodo water or aggregate, silicic acid sol or silicate sol and synthetic m-fat emulsion M are obtained.
The mixture reacts with the fly ash and pozzolan, causing it to become even stronger and less prone to cracking. Therefore, when the foaming agents and additives mentioned above are mixed with the material and subjected to vacuum treatment4, the strength of the mortar, concrete, or these foam-containing materials increases synergistically. However, if Fryara/=L or pozzolan is mixed, cracks will occur and the strength will increase.

This invention is constructed as described above, and blast furnace slag, foamed concrete, aerated cement, etc. can be used as fertilizer in themselves, but if they are fed with ingredients that are lacking, inorganic fertilizers such as potassium, organic fertilizer #+, etc. can be added. After being impregnated and dried, it is used as a slow-release or long-lasting fertilizer.
Products impregnated with dyes can make unattractive wood beautiful or produce wood with unprecedented colors. Products impregnated with Borono C manufactured by Co., Ltd. or a silicon a1 resin emulsion can have low water permeability, and can be used to impregnate foamed materials such as aerated concrete with resin or metal molds, or Metals impregnated with cement or #grease not only have the properties of excrement-containing substances, but also can remove salt from sea sand, and can also be used to remove salt from sea sand using the same equipment. - Continuously supply sea sand and water to the FC11F disclosed in Japanese Patent Application No. SG-1BXA, which has many effects such as being able to make mortar and mortar. If the pressure-transformed material is discharged and the sand and water are separated at the discharge port, it is possible to continuously remove salt from four sands, and this invention is limited to the examples. It's not something
