Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
The basic structure of the strongly acidic solution sensor 200 of the embodiment of the present invention one is identical with the structure shown in Fig. 1 and Fig. 2, therefore, this emphasis to basal film layer the 210th, conductor wire as shown in Figure 3 211st, 212 and the composition of upper protective film layer 230 illustrate.
It is known that when poisonous strongly acidic solution leaks in soil or air, it may occur that water pollution, soil pollution, air pollution etc., not only can destroy material, and can have a strong impact on health.Accordingly, it would be desirable to a kind of quickly acid solution leak detection technology of economy.
To this end, present invention basal film to be ensured layer the 210th, conductor wire the 211st, 212 and upper protective film layer 230 at highly acid toxic chemical solution such as sulfonic acid, hydrochloric acid, nitric acid, hydrofluoric acid, i.e. acid solution does not dissolves.
Basal film layer 210 of the present invention is by PC, PP, PE, PET, PI, PIFE(Teflon) etc. synthetic resin constitute, its thickness is 50~300.
The 211st, described conductor wire 212 is had the linear conductive carbon dispersion liquid of conduction and acrylic acid resin or PE or PU by activated carbon, CNT (CNT:Carbon Nano Tube), Graphene (Graphene), carbon black (Carbon black) etc. or the adhesive such as PC or epoxy resin mixes and forms.40~90 weight percent conductive carbon dispersion liquids and 10~60 weight percent binder mix and form electric conductive carbon printing ink, described electric conductive carbon printing ink can be printed on basal film layer 210 by various mode of printings such as intaglio printing, silk screen printing, air brushing, to form conductor wire the 211st, 212.
When mixing acrylic acid resin as adhesive, and adhesive 10~60 percentage by weight being converted into 100 percentage by weight, its blending ingredients is the volatile solvent of the acrylic acid resin of 40~60 percentage by weights and 40~60 percentage by weights.Wherein, acrylic acid resin not only has anti-highly acid, and has powerful adhesive force when being printed on basal film layer 210, and described volatile solvent then can improve volatility during printing, makes printing process be more prone to.
If additionally, using PE or PU or PC or epoxy resin etc. as adhesive use when, it is also possible to the volatile solvent of PE or PU or PC of 40~60 percentage by weights or epoxy resin and 40~60 percentage by weights mixes.
When conductive carbon dispersion liquid 40~90 percentage by weight is converted into 100 percentage by weight, in 100 percentage by weights, activated carbon or CNT or Graphene or carbon black powder 1~20 percentage by weight, ethyl cellosolve solution 80~98 weight percent form paste after when non-ionic surfactant Series Dispersant 1~10 percentage by weight mixes.Wherein, CNT, Graphene or carbon black powder have electric conductivity, and ethyl cellosolve and non-ionic surfactant Series Dispersant, for stablizing the structure of conductive carbon, make particle dispersion more uniform.
Additionally, also the alcohol Series P H values such as IP available A, water, ethanol or methyl alcohol are the neutral range of solvents replacement ethyl cellosolve solution of 6.5~7.5.
As described above, conductive carbon dispersion liquid can be used, and form conductor wire the 211st, 212 by the various ways such as intaglio printing, now, conductor wire the 211st, 212 thickness be 2~20.
Described upper protective film layer 230 is made up of synthetic resin materials such as the PC with anti-strongly acidic solution characteristic, PP, PE, PI, PET, Teflons, and thickness is 50~300, and corresponding conductor wire the 211st, 212 position be provided with sensing bore 231.
When there is leakage in strongly acidic solution, strongly acidic solution is flowed into by the sensing bore 231 that leak occurs, with constitute conductor wire the 211st, 212 adhesive react, and As time goes on described adhesive generation bulging, make the arrangement generation avalanche of conductive carbon ion, as shown in Figure 4.
Thus, conductor wire the 211st, 212 resistance value increase, remote controllers by receive described conductor wire the 211st, 212 increased resistance value, it may be judged whether have strongly acidic solution to leak.
At this moment, the 211st, described conductor wire 212 can be made up of various ways, as shown in table 1.
Table 1:
When the first conductor wire 211 and the second conductor wire 212 are mixed with adhesive by activated carbon or carbon black or CNT (CNT) or Graphene (graphene), sensing bore 231 is set in the position corresponding with described first conductor wire and the second conductor wire.
But, when the first conductor wire 211 is made up of electric conductors such as silver compound, sheet metal electrically conductive inks, when second conductor wire 212 is then mixed with adhesive by activated carbon or carbon black or CNT (CNT) or Graphene (graphene), only sensing bore 231 is set in the position corresponding with the second conductor wire 212.
This is because need when the first conductor wire 211 is formed by the more weak material of resistance to strongly acidic solution ability to be protected.
Fig. 5 is the schematic diagram for confirming whole systems that whether strongly acidic solution leak.As shown in Figure 5 a, the two ends of strongly acidic solution sensor 200 are connected with top connector 400 and terminator terminating junctor 500, described top connector 400 is connected with controller 300, and described terminator terminating junctor 500 then connects conductor wire the 211st, 212 in the termination of strongly acidic solution sensor 200.
Fig. 5 b is a kind of embodiment circuit diagram.The material that the second conductor wire 212 in this circuit diagram is made resistance value change by reacting strongly acidic solution is formed, and the first conductor wire 211 is formed by electric conductor.When strongly acidic solution leaks, and being flowed into by sensing bore 231, when contacting with the second conductor wire 212, the resistance value of described second conductor wire 212 changes.According to this resistance change situation, remote controllers 300 confirm whether strongly acidic solution leaks.
Fig. 6 is the schematic diagram of the embodiment of the present invention two.As shown in Figure 6; the strongly acidic solution sensor 200 of the present invention lower adhesion layer the 220th, the basal film layer 210 that lamination is arranged successively from the bottom to top and upper protective film layer 230, described basal film layer 210 is provided with the conductor wire being separated by side by side and putting the 211st, 212 along its length.In order to cover conductor wire the 211st, 212 top, utilizing coating, alkyd resin, PE, PET, PC, aldehyde resin (POM), the soluble or easy resin material corroding in strong acid such as polymethyl methacrylate (PMMA), polyamide (PA), ionomer, polyarylate, polyester elastomer (PEE), phenolic resin (PF) forms coat 240.Described coat 240 is dissolved in strongly acidic solution, but water insoluble, and it can be formed by bar type coating (Bar coating), the slit coating mode such as (slot die), intaglio plate coating.
Described coat 240 can be formed by multiple polymer composites, and the 211st, conductor wire 212 can be formed by conductive materials such as ink, silver compound, sheet metal or thin plates.
Therefore, when water is flowed into by sensing bore 231, the 211st, conductor wire 212 cannot be energized under the waterproof action of coat 240.But, when strongly acidic solution flows into, coat 240 occurs to dissolve or be etched, resistance value is made to change, so that the conductor wire being formed by conductive material the 211st, 212 energising, cause resistance value to change, can detect whether strongly acidic solution leaks according to resistance change situation.
Now, the thickness of coat 240 is 2~20.
Described coat 240 is preferably mixed by coating 90~99 percentage by weight and curing agent 1~10 percentage by weight, and described curing agent can use isocyanates or melamine.
Strongly acidic solution includes sulfonic acid, hydrochloric acid, nitric acid, hydrofluoric acid etc., of a great variety.Conductor wire as above 211st, 212 energising make the structure that resistance value changes, the resistance change situation detection leak condition that can only occur according to leaking with strongly acidic solution, and be difficult to confirm the species of the strongly acidic solution of leakage.
The present invention can confirm to occur the species of the strongly acidic solution of leakage according to time dependent resistance value.
Described controller 300 receives increased resistance value or conductor wire the 211st, 212 increased resistance value occurring because of energising of the conductor wire 212 described in embodiment one and embodiment two, and confirm the resistance value changing in time, according to the species of its result identification strongly acidic solution.
Structural representation when Fig. 7 a is to be connected with controller in strongly acidic solution of the present invention leakage sensing device embodiment two, electrical block diagram when Fig. 7 b is to be connected with controller in strongly acidic solution of the present invention leakage sensing device embodiment two.As shown in Fig. 7 a, 7b, the two ends of strongly acidic solution sensor 200 are connected with top connector 400 and terminator terminating junctor 500, described top connector 400 is connected with controller 300, and described terminator terminating junctor 500 then connects conductor wire the 211st, 212 in the termination of strongly acidic solution sensor 200.
The running status chart of the controller 300 according to the resistance change situation identification strongly acidic solution species between two conductor wires the 211st, 212 when Fig. 8 is the coat 240 being formed such as embodiment two for explanation.Described controller 300 is set with the reference resistor value of the sensor length based on strongly acidic solution sensor 200, on the basis of described reference resistor value, be set with "+" compensate (offset) value and "-" offset, to compensate the change of the self-resistance value causing because of factors such as outside temperature, humidity, electric noise, physical contacts.
Described offset can be adjusted according to the installation environment of strongly acidic solution sensor 200.
Described controller 300 be set be positioned at reference resistor value "+" alarm set value (High Limit) in direction, i.e. upper limit resistance value and the alarm set value (Low Limit) being positioned at resistance value "-" direction, i.e. lower resistance value.Can adjust sensing sensitivity by the scope regulating alarm set value.
It when strongly acidic solution occurs leakage, is gradually lowered and enters the time in range of set value by the resistance value between mensuration conductor wire the 211st, 212, identify the species of strongly acidic solution.
For example, when chemical solution A leakage, when contacting with coat 240, coat 240 dissolves or is etched, and makes resistance value change.At this moment, the time in the range of controller 300 measures the resistance value entrance alarm set value starting to change to change from resistance value, and according to the species of its minute identification strongly acidic solution.
For chemical solution B, chemical solution C and chemical solution D, compared with chemical solution A, in the range of resistance value utilizes relatively short period of time just to enter alarm set value after starting change, described controller 300 is identified the strongly acidic solution species of leakage by measuring this kind of time.
When the increased resistance value of various chemical solutions is consistent with alarm set value (High Limit), send alarm at this positioner 300, continue the change of induced electricity resistance afterwards.A certain specified chemical solution is such as chemical solution D, and resistance value changes makes it exceed alarm set value (Low Limit), when, controller 300 is beyond alarm set value (Low Limit) position sends alarm.
Various strongly acidic solution time dependent resistance value data are stored in described controller 300, therefore, start to change to the time in the range of increased resistance value enters alarm set value by measuring from resistance value, send to should the chemical solution i.e. alarm of strongly acidic solution species of time.
For embodiment one, when under the effect of acid solution, the resistance value of conductor wire 212 increases, elapsed time is longer, and resistance value is bigger.
I.e., according to embodiments of the present invention one and embodiment two, when conductor wire the 211st, 212 resistance value be decreased or increased when, the strongly acidic solution species of leakage according to resistance value degree over time, can be identified.
In addition, strongly acidic solution of the present invention leakage sensing device can substitute described banding pattern strongly acidic solution sensor 200 with cable type sensors.As it is shown in figure 9, the 610th, cable sensor 600 by two strands of conductor wires 620 is separated by side by side and puts, the clad 630 being made up of the material being dissolved in strongly acidic solution outside it, can be coated.
Described clad 630, as the coat 240 of the present invention, can be formed by coating after CNT (Carbon Nano Tube) dispersion liquid 60~90 percentage by weight and acrylic acid resin 10~40 percentage by weight containing volatile solvent mixing.
Described clad 630 can be formed by the material dissolved under the effect of strongly acidic solution or corrode.
Therefore, when strongly acidic solution is contacted with described clad 630, described clad 630 dissolves, and makes resistance value change, and conductor wire the 610th, the resistance value between 620 also changes therewith.
Other principles are described above.
In addition, when conductor wire the 211st, 212 formed by activated carbon or carbon black or CNT (CNT) or Graphene (Graphene) when, mode of printing can be used, also can by prepare to be formed on basal film layer 210 conductor wire the 211st, 212 position sticking two-faced adhesive tape or coating adhesive formed after adhesive agent 211-1,212-1, spread powdered carbon black or CNT (CNT) or Graphene (Graphene) and formed, as shown in Figure 10.
That is, by conductive powder is sprinkling upon adhesive agent 211-1,212-1 upper formation conductor wire the 211st, 212.
Therefore, only could adhere to electrical conductivity Carbon black or CNT (CNT) or Graphene (Graphene) in the place being formed with adhesive agent 211-1,212-1 and form conductor wire.
Additionally, utilize spraying (suttering) method also can form conductor wire the 211st, 212.Described spraying method is to arrange to have the metal of electric conductivity and basal film layer 210 of the present invention in vacuum chamber, now, described basal film layer 210 will overlap in addition to the position of conductor wire to be formed upper protective film 213, as shown in figure 11.
Described diaphragm 213 can be made up of synthetic resin adhesive tape.
Adding negative voltage on conducting metal, after adding positive voltage, injecting argon gas in vacuum chamber on basal film layer 210, the ion deposition at this moment spilling because ionization argon gas clashes with conducting metal is at basal film layer 210.
Depositing operation removes diaphragm 213 after terminating, just form conductor wire the 211st, 212.
Why use above-mentioned spraying method, be because when conductor wire the 211st, 212 formed by conductive materials such as electrically conductive ink, silver compound, sheet metal or thin plates when, its thickness is 5~10, there is bigger resistance value, if being coated coat 240 at an upper portion thereof, then conductor wire the 211st, 212 and the thickness of coat 240 will reach 30~50, additionally, being affected by conductor wire the 211st, 212 thickness, coat 240 is difficult to be stably adhered on basal film layer 210.
But, if use spraying method, conductor wire the 211st, 212 thickness be only 0.1~1, thickness diminishes, thus coat 240 can be made to be stably adhered on basal film layer 240.
Additionally, be formed at basal film layer 210 conductor wire the 211st, 212 not necessarily two above, available by activated carbon or carbon black or CNT Or Graphene (Graphene) only forms a conductor wire with the material that adhesive mixes the above of basal film layer 210 (CNT).The two ends of one conductor wire can be connected to controller by conductive cable.
