Description

Method of and apparatus for injecting treating liquid into wood material and porous inorganic material, and method for destroying ray......
The present invention relates to inject the method and apparatus of timber and stone material such as the treatment fluid of resin.Or rather, the present invention relates to inject the method for treatment fluid, improving the preservation of timber against decay, insect protected, anti-ant property, mildew resistance, fire line, dimensional stability and to gain in strength, and the acid resistance that improves stone material.The invention still further relates to the method that parenchymal tissue is penetrated myelocyte wall and air-breathing pitpair of destroying.
Up to now, used and all treatment fluid has been injected the method for timber, with the fire line, anti-corrosive properties, insect protected, the dimensional stability that improve timber and gain in strength.
By being forced into a particular pressure value at short notice and this pressure is kept distance, thereby treatment fluid is injected timber.In such cases,, timber kind generally must not surpass 15kg/cm no matter how, injecting the employed pressure of treatment fluid 2, will cause timber distortion, for example warpage, bending or attenuation because surpass this value.
In recent years, a big problem that has been damaged to Europe of the building made of stones that causes by acid rain.People have taked all measures protection stone material to exempt from acid rain to corrode, and for example inject treatment fluid and utilize the characteristic of stone material itself in stone material, and for example marble neutralizes and falls the characteristic of its surperficial sour water.
Timber generally is made of many cell masses, as shown in Figure 8.A kind of structure that each iuntercellular is made up of wall body pitpair 1, these pitpairs are scattered everywhere and are formed cinclides 2, as shown in Figure 9.The center of cinclides 2 is the super-elasticity part, is called torus 3.Around the torus 3 is very thin net (margo).In having the timber of this class formation, this timber is being processed in the process of core wood and so on, the wall of cinclides is pulled to one of the opening in hole, thus torus 3 is with the opening obstruction in hole.Timber under this state is called as the air-breathing pitpair of formation.When timber formed air-breathing pitpair, torus 3 was blocked cinclides 2.Core wood and subcortical alburnous cinclides are also stopped up by torus.Therefore, be penetrated into timber everywhere, must destroy the torus 3 that stops up air-breathing pitpair cinclides opening or destroy cell membrane itself, make treatment fluid can infiltrate flanking cell for making treatment fluid.
Reach the material center in order to destroy torus 3 always, use conventional treatment fluid injection method just need be forced into 30kg/cm 2Yet,, be forced into 15kg/cm by above-mentioned way 2Or bigger, timber deforms.Thereby have under the unlikely low pressure that causes timber distortion, inject.Such pressure can't fully destroy torus 3, can't be injected into timber inside to the treatment fluid of capacity.
On the other hand, particularly for broad leaf tree, be added to pressure to one predetermined value on the timber.Therefore, the impurity such as thylose results in blockage in conduit, thereby is difficult to treatment fluid is injected into the timber depths.
In addition, because treatment fluid only is added on the surface of stone material, and because the character of stone material itself, stone material is that its surface is protected.Along with stone material is subjected to the erosion of acid rain for prolonged period of time, its acid-resisting weakens, and causes and resists the inefficacy that acid rain is taken measures.Therefore, acid rain penetrates into stone material inside, internally stone material is eaten sky, makes stone material inside become powdery.
The present invention is intended to overcome the problems referred to above, thereby for making its inside that penetrates into them that a kind of method and apparatus is provided, does not cause the distortion of timber, stone material and other processed material simultaneously again to treatment fluid injection timber and porous inorganic material.Another object of the present invention provides a kind of method that parenchymal tissue is penetrated myelocyte wall and air-breathing pitpair of destroying.
Above-mentioned purpose is by having used the method for treatment fluid being injected timber and porous inorganic material relevant with the present invention to reach, and this is the method for the treatment fluid of a kind of injection such as resin.This method comprises following steps: pressurization just, and cause the giving of distortion decide force value on processed material to pressurize and keep give fix time with unlikely this moment; Precharge, promptly press under the normal pressure keep one give fix time after, the pressure that increases material gradually is up to final pressure, when each pressurization, keeps one to give and fixing time this pressure in step; Inject treatment fluid, at this moment, be injected into processed material with the pressure that gives fixed injection treatment fluid.
This kind treatment fluid injection method is best suited for the treatment fluid such as resin is injected coniferous tree.This method comprises following steps: decompression, reduce the pressure of processed material this moment, to remove gas wherein; Pressurization just, this moment with the low pressure that do not cause the processed material distortion to its pressurization and keep giving and fix time; Precharge, promptly keep under the above-mentioned pressure one give fix time after, progressively supercharging is up to final pressure, and when supercharging each time, keeps one to give and fixing time this pressure; Inject treatment fluid, inject processed material to give fixed injection pressure with treatment fluid this moment.
The treatment fluid injection method also can be used as the method for the treatment fluid such as resin being injected broad leaf tree.This method can comprise following a few step: decompression, at this moment, reduce the pressure on the processed material, and the used time is longer than coniferous tree, with venting gas wherein; Just pressurize, add low pressure this moment on broad leaf tree, make it indeformable, and keep than the longer time of coniferous tree, precharge, and promptly after keeping the fixed time under the above-mentioned pressure, progressively to the material supercharging, each supercharging is given with certain pressure maintenance one and being fixed time; And the injection treatment fluid, inject treatment fluid with predetermined treatment fluid injection pressure this moment.
The treatment fluid injection method also can be used as the method for the treatment fluid such as resin being injected stone material.This method can comprise the steps: decompression, and reduce the pressure of stone material this moment, and the used time is longer than timber, to remove gas wherein; Just pressurization adds the unlikely low pressure that causes distortion to stone material, and the time is longer than timber; Precharge; Promptly keep with above-mentioned pressure one give fix time after, the pressure on the stone material is added to final pressure; Inject treatment fluid, promptly treatment fluid is injected processed material with predetermined treatment fluid injection pressure.
According to the treatment fluid injection method relevant with the present invention, according to processing type of material and internal structure thereof, change decompression time or pressing time or pressurized conditions, can effectively treatment fluid be injected wood raw material, and be difficult to accomplish this point with conventional method until the reel place; And can inject the capacity treatment fluid effectively to the stone material centre, and stone material is not injected with conventional method.
Therefore, timber has improved anti-corrosive properties, insect protected, anti-ant property and mildew resistance greatly, thereby has increased the life-span of timber.And, treatment fluid injected the center and make it can't seepage, can guarantee that timber does not rupture for a long time, thereby improve its dimensional stability.In addition, use the fire prevention treatment fluid that it is annotated all over the center, the timber that uses this method to handle has good fire line and dimensional stability, and they just can be used for all occasions.And the increase in timber life-span helps to stop the no plan felling to tropical forest, and this is a big problem in recent years, and therefore from the viewpoint of forest conservation, this method also is exceedingly useful.
Stone material also can protectedly exempt from acid rain and corrode, thus the unlikely deterioration of its characteristic.Skin can protectedly exempt from the infringement of acid rain, and acid rain has the area of many buildings made of stones there, such as West Europe, is a big problem.In other words, according to the present invention, the unnecessary skin of forbidding is used marble and other stone material.The present invention has prevented that not only building stones are damaged, and to preserving the cultural of a country and concerning environmental protection, also being exceedingly useful.
The present invention is also for providing a kind of device treatment fluid injection timber and porous inorganic material.This device comprises that one stores and the pressure vessel of sealing processed material, one are pressed jar with treatment fluid to removing of linking to each other with above-mentioned pressure vessel of the liquid pressurizing vessel, of above-mentioned pressure vessel pressurization, apply the pressure identical and one thereon and press removing that jar links to each other to press valve with removing, open and close this and remove and press valve to press the pressure of jar removing gradually in the pressure vessel by removing with reservoir pressure.
This device prevents the destruction that air expands and causes material in removing the pressure process, can make treatment fluid injection material deep.
The present invention also provides a kind of method that parenchymal tissue is penetrated myelocyte wall and air-breathing pit of destroying.The method comprises the following steps; Decompression is promptly removed gas in the processed material by decompression; Pressurization just promptly applies one with the pressure that do not cause the processed material distortion to it and gives level pressure power and keep one to give and fixing time under this pressure; Precharge promptly after finishing above-mentioned steps, progressively is pressurized to final pressure, and when each supercharging, keeps one to give and fixing time this pressure.

Below with reference to accompanying drawings the embodiment of treatment fluid injection method of the present invention is set forth.
Fig. 1 expresses and uses this method that treatment fluid is injected acerose decompression and pressurization figure in first kind of embodiment of the present invention.Fig. 4 and Fig. 5 illustrate acerose structure.Fig. 6 compares the situation of timber after injecting treatment fluid with this method and conventional method.Fig. 7 is the assembling block diagram of the treating apparatus of realization this method.
Acerose structure generally as shown in Figure 4 and Figure 5.Therefore, must destroy that parenchymal tissue is penetrated the myelocyte wall and air-breathing pitpair could be injected the depths with treatment fluid.In the methods of the invention, amount of pressure begins progressively to be added on the processed material from low pressure, is enough to destroy torus 3 but is unlikely in the scope that makes timber distortion thereby the pressure reduction inside and outside the timber remained on.The portion depths is destroyed from outside to inside gradually for all toruses 3, thereby makes the treatment fluid of injection fully be penetrated into the deep of timber.
At first, outermost parenchymal tissue penetrates the myelocyte wall and air-breathing pitpair is damaged, and makes the pressure at test-tube baby 21a place equate with ambient pressure then.Along with torus from outside constantly destroyed to reel, the pressure at test-tube baby 21b, 21c place is equated with ambient pressure.At this moment, pressure is to conduct by very narrow and small space or aperture.Therefore, must intensified pressure raising the efficiency, but the supercharging meeting causes material attenuation or distortion quickly.Therefore, in the present invention, pressure progressively improves constantly, thereby prevents material attenuation or distortion.
In depressurization steps of the present invention, processed material 11 is sealed up for safekeeping in the pressure vessel 12 of device shown in Figure 7, then as shown in Figure 1, with reduced vacuum pump 13 pressure on the material is temporarily reduced to 760mmHg, and material was kept under this pressure about 20 minutes, to remove the air in the material as much as possible.Subsequent is pressurization.In first pressurization steps, use gas pressurized compressor 14 with 2Kg/cm 2Pressure be added on the material.At this moment, according to Bath fastening rule, all parts of the material in the pressure vessel 12 all are subjected to identical pressure.Material kept 20 minutes under this pressure.2Kg/cm 2Pressure be enough to destroy all toruses 3 and similar structure.Therefore, do not penetrate the myelocyte wall and air-breathing pitpair is damaged though material is all parenchymal tissues when remaining under this pressure, a part wherein has been subjected to destruction, thereby makes pressure can conduct to the centre.Under this lower pressure, timber itself can not be out of shape.
Next step is precharge.As shown in Figure 1, pressure is the 2Kg/cm from first pressurization 2Progressively be pressurized to final pressure.In the present embodiment, pressure increases to 8Kg/cm 2, 15Kg/cm 2And 25Kg/cm 2
Pressure increases to 8Kg/cm earlier 2The 2Kg/cm owing to pressurizeed during pressurization just 2, increase to 8Kg/cm at pressure 2Therefore the inside and outside relative pressure difference of Shi Mucai is 6Kg/cm 2No matter the kind of timber how, be subjected to 2-5Kg/cm 2Pressure the time, torus 3 generally all can be destroyed.Therefore, in the phase I of precharge, a large amount of air-breathing pitpairs, mainly be that the air-breathing pitpair at the peripheral place of timber is destroyed.Material is at 8Kg/cm 2Pressure kept about 10 minutes down.Therefore, mode same as described above, pressure penetrates the myelocyte wall by ruined parenchymal tissue and air-breathing pitpair is conducted, and makes the timber depths also be subjected to 8Kg/cm 2Pressure.
In the precharge step, pressure further improves at the appropriate time, and in each pressure period, all certain pressure is kept certain hour.Also promptly, here, pressure further increases to 15Kg/cm 2, kept 10 minutes, increase to 25Kg/cm again 2, kept 20 minutes, up to the final pressure period.Inside and outside relative pressure difference in each stage is constantly destroyed parenchymal tissue and is penetrated myelocyte wall and air-breathing pitpair.
As mentioned above, timber is being subjected to 15Kg/cm usually 2Pressure the time can be out of shape.But the distortion of timber is owing to be pressurized to 15Kg/cm from no pressure quickly 2The rising suddenly of the formed pressure differential of pressure causes.Therefore, if as the present invention, progressively increase timber pressure, even final pressure surpasses 15Kg/cm 2, also be unlikely and cause timber distortion.
In the present invention, in each stage, pressure keeps certain hour, thereby makes timber inside also be subjected to added pressure of this stage.Therefore, even add for example 25kg/cm 2Pressure, the pressure increase in pressure process only is that the relative pressure inside and outside the timber is poor.Also promptly, the suffered pressure of timber only is 10Kg/cm 2(25Kg/cm 2Deduct previous pressure 15Kg/cm 2), can not cause distortion.
Therefore, according to the present invention, progressively the precharge of Shi Xianing makes air-breathing pitpair and so on be corrupted to the timber depths always, and don't causes the distortion of timber itself.
In each pressure period, be preferably in pressure is added to 15Kg/cm 2Several leading stage in, in the long period that keeps under the certain pressure more than 10 minutes, pressing time can be short slightly thereafter material.
The numerical value of the pressure in each stage and pressure differential and the certain hour that material kept under certain pressure nature is along with the kind of timber and big or small different and different.For example, when the needs high pressure destroyed pitpair 3, pressure differential must be big; When chien shih timber deep reached certain pressure when needed, timber must keep the long time under this pressure.
Be to inject treatment fluid after the precharge.Use this moment liquid force (forcing) pump 15 that treatment fluid is oozed all over material.Here, according to henry's law, the gas that remains in the timber at test-tube baby 21 places can infiltrate in the treatment fluid under institute's plus-pressure.
Material can be handled under the pressure identical with final pressure in the precharge step, perhaps also can be handled under different pressure.In the method, because parenchymal tissue is penetrated the myelocyte wall and air-breathing pitpair has been corrupted to the timber depths, precharge can make treatment fluid infiltrate the timber depths easily.Therefore, material can be to be handled under the pressure that is lower than the conventional pressure that injects treatment fluid.
After injecting treatment fluid under institute's plus-pressure, must remove the suffered pressure of material.At this moment,, remove the rapid expansion that pressure can cause the gas of infiltration in treatment fluid suddenly, thereby destroy material itself according to henry's law.Therefore, in the present embodiment, in treating apparatus, installed specially and remove to have pressed jars 18, this remove press jar add in advance upward pressure with eliminate and pressure vessel 12 in pressure differential between the pressure.Pressure jar presses valve 19 slowly to be eliminated by removing from remove pressing, thereby allows the gas that is dissolved among the treatment fluid at first overflow.The low-molecular-weight gas that is dissolved in the treatment fluid at first flows out material, thereby makes treatment fluid concentrate at the material depths.
Fig. 6 has expressed the situation of the timber of handling through the treatment fluid injection method of treatment fluid injection method of the present embodiment and routine, so that two compare.Use this method and conventional method that water-soluble dyestuff is injected timber, treated timber is cut compare (having used water content 55%, size is Japanese China fir and the pine tree core wood of 20 * 20 * 100cm) then.From Fig. 6 obviously as seen, the timber of handling through conventional method only has a small amount of treatment fluid to enter at the incision surface place, and does not almost have treatment fluid to inject in other surface.On the other hand, by the inventive method, treatment fluid in any direction all can inject, from the band direction, all inject from straight burr direction and other direction.Also be, by this method, thereby the parenchymal tissue in the material is penetrated the myelocyte wall and the destroyed treatment fluid that allows of air-breathing pitpair injects, thereby treatment fluid not only is injected into material surface equably, and be injected into the material depths, core wood also just without a doubt as processed material.The present embodiment comprises the precharge of using gases, then is to inject treatment fluid, at first destroys air-breathing pitpair when precharge, but also can be progressively directly to inject treatment fluid under institute's plus-pressure.In this case, the injection of treatment fluid is to realize by putting processed material 11 into pressure vessel 12, treatment fluid is full of this container, pressurizeing then.Injection rate is regulated by pressure, detects with the hydraulic levels meter 17 that is contained in the flow container 16.
Available injection liquid comprises with being mixed with the cation surfactant emulsification of anticorrisive agent, pesticide, ant killing agent and mould inhibitor and making it become water-soluble vegetable oil and mineral oil.Thereby the treatment fluid that is injected into of cationic property combines with the timber of anionic nature and prevents to leak out timber, thereby it is suitable for as treatment fluid.Compare with the aqueous ethylene glycol as treatment fluid, these treatment fluids can prevent seepage, and keep better dimensional stability in for a long time.And, with nonionic and cation surfactant emulsification they and mix into that anticorrisive agent also can obtain same effect.In addition, because this method can be injected treatment fluid the timber deep, can obtain than the higher material of processed conventionally material fire protecting performance by injecting fireproof agent.
Set forth second kind of embodiment of treatment fluid injection method of the present invention below.Second kind of embodiment is a kind of method of treatment fluid being injected broad leaf tree.Fig. 2 has expressed decompression figure and the pressurization figure in the processing procedure.
Different with aforementioned coniferous tree, broad leaf tree had the conduit of water usually.Therefore, as if these conduits can be used for injecting easily treatment fluid.But, in fact contain a large amount of impurity such as thylose in these conduits.Thereby one plus-pressure just can cause these impurity to stop up in catheter center, the injection of treatment fluid can't be carried out.Therefore the present embodiment is intended to by applying lower pressure in longer a period of time, thus do not make impurity be blocked in method in the conduit will same pressure conduct to the timber depths and there notes advance treatment fluid.
As shown in Figure 2, this method is decided to be 60 minutes with decompression time, this is than long by the fixed time of coniferous tree, because broad leaf tree is compared with coniferous tree, comprise more composition in its conduit, therefore be necessary to reduce to the degree that conduit in the pressure process stops up minimum by disposing the air in the conduit as much as possible.
Even in following pressurization steps, also only apply the lower 1.5kg/cm that is about 2Pressure, thereby conduit is not stopped up.Be decided to be 30 minutes pressing time, this is than coniferous tree duration (referring to Fig. 2).Therefore, conduit can be under the certain pressure, is not done harm to by conduit stops up again.After applying low pressure for a long time, progressively be pressurized to 7Kg/cm 2, for the time 10 minutes, 30Kg/cm 2For the time 30 minutes, or the like.Here, the plus-pressure step of broad leaf tree can increase than acerose step to be lacked, because broad leaf tree has more substantial conduit composition, behind the injection treatment fluid, as previously mentioned, uses to remove and presses valve 19 to remove pressure gradually.
Gained result identical with coniferous tree (used water content is 60%, size be japanese oak and the beech core wood of 20 * 20 * 100cm).
Fig. 3 is illustrated in decompression figure and the pressurization figure in the material processed process of the third embodiment of treatment fluid injection method of the present invention.The present embodiment is a kind of treatment fluid to be injected porous inorganic material, for example method of stone material.In the method, reduce pressure and to add the low pressure time all very long.After this, pressure increases to high pressure quickly, and treatment fluid is injected the stone material depths.
The porous inorganic material of marble and so on since its configuration aspects former thus within it portion contain a large amount of gases.Therefore, give the capacity time in the method with abundant removing internal gas.At this moment, decompression time is longer than the situation of above-mentioned broad leaf tree, is about 120 minutes.
A large amount of tiny impurity or fine powders are also contained in building stones inside.Therefore, stop up, apply and be about 5Kg/cm for preventing them 2Time of lower pressure than timber duration, for example be approximately 60 minutes, make stone material inside be under the certain pressure, this situation with broad leaf tree is identical.In the present embodiment, after applying the low pressure of a very long time, different with timber is just to apply 30Kg/cm quickly 2High pressure because stone material is not easy to be out of shape because of pressurization.
Except using compressor gas precharge, inject under pressure then outside the treatment fluid, also can use liquid pump and pressurize by the direct pressing mode of treatment fluid.On the other hand, under high pressure inject treatment fluid after, use to remove press valve 19 to remove gradually and press, as previously mentioned.
Therefore, according to method of the present invention, treatment fluid is injected into the material depths.The Italy of 2 * a 40 * 80cm produces marble and is taken as the building stones injection water stain, cuts then.Find this marble up to the depths by level dyeing, thereby the treatment fluid that is injected into of proof has really reached the depths of material.
In the present invention, used " only water does not advance " (trade (brand) name) of Japan, its Main Ingredients and Appearance is a silane monomer, thereby has further increased the antiacid rain of processed stone material.Also promptly, silane monomer in the base-material and silanol chemical combination generate one deck high efficiency water-proof layer, thereby the protection stone material exempts from the infringement of acid rain etc.Therefore in addition,, can utilize itself characteristic to handle stone material, not reduce marmorean gas permeability simultaneously again because the hairnet hole in stone material, the particularly marble is not wherein buried.
