Background technology
Protein adsorption/go to adsorb also is ubiquity and very complicated spontaneous phenomenon, stops the non-specific adsorption of protein, always is the significant challenge that colloid and interface science research face.In food processing process, mechanical inside surface is exposed to Biomedia, usually can be contaminated because of the non-specific adsorption of protein and other.Protein adsorption and subsequent microbial growth, the serious harm food sanitation and safety.On boats and ships surface and mesh screen, the adhesion of biomolecule and microorganism all can cause adverse consequences, for example stops up mesh, increases ship resistance, and the etching mechanism surface, shortens its serviceable life.The development of man-made organ, organizational project, biochip, biology sensor etc. also all must consider to stop the non-specific adsorption of protein in the biomedical engineering.
The article of having delivered and disclosed patented claim show that nano bubble can be used for the conductive surface absorption and control of Biomedia.Nano bubble not only can be prepared in conductive surface in advance, significantly reduces the absorption of surface protein, also can receive bubble in the preparation of the surface of adhesion protein, and adhesion protein goes absorption.
At present, nano bubble goes to there is no instrumentation in absorption research and the practical application, main dependence manual operations.Affect nano bubble and go adsorbing factor a lot, comprise electrolyte (kind, concentration), interelectrode distance, power supply (voltage, electric current, power), time etc., there is no device and can regulate comprehensively and record these parameters.This has just caused in research and using, and nano bubble goes the reappearance of absorption result relatively poor.
In the problems referred to above, electrolytical consistance is controlled easily, and the processing time also can hold, and the device of the present invention's design can be in order to solve other two problems, i.e. power supply and electrode separations.Suitably use this device, can realize and can repeat, regulatable nano bubble preparation, and estimate its anti-soil effect.
Summary of the invention
The objective of the invention is the problem for the prior art existence, a kind of nano bubble preparation and anti-soil evaluation of effect device thereof are provided.
Specifically, apparatus of the present invention comprise two parts: the one, and adjustable stabilized power source [9] namely under different electrochemical treatment conditions, according to the input parameter power supply, provides constant voltage, constant current or firm power power supply; The 2nd, supporting structure (as shown in Figure 1 and Figure 2), its structure adopts insulating material to make upper and lower two panels, by insulating material support column [3] that two panels are parallel fixing, a panel is as bottom panel [2], one termination electrode [A, B, C] be fixed on the bottom panel [2], this termination electrode is made of metal electrode pad [6] and wire; Another panel is as top panel [1], and on other end electrode [α, the beta, gamma] plate that is fixed in the above [1], this termination electrode has the electrode screw rod [4] of scale mark to consist of by knurled nut [7] and side, and adjustable stabilized power source [9] is connected with the electrode at two ends respectively.
Electrode of the present invention is not limited to three groups, also can be multi-group electrode still less or more, the test job amount that view apparatus requires and deciding.
This device can be realized that the electrochemical treatment condition is controlled, can repeat, and is so that consequent nano bubble and antifouling, the dirty effect of dispelling thereof also can repeat, controlled.
Apparatus of the present invention are in the workpiece process, can be with three groups of electrodes or serial or parallel connection, and be output as constant current or constant voltage according to different electrochemical treatment condition setting power supplys, consistent by the current parameters of tested conductor on every group of electrode to guarantee, guarantee the stable of power parameter (electric current, voltage, power).
Electrode separation of the present invention is by knurled nut [7] and electrode screw rod [4] control of the electrode of top panel end.The pitch of electrode screw rod [4] can be set as a fixed value, and the scale on knurled nut [7] surface is divided into corresponding share with the interior girth of nut, and the cooperation of knurled nut [7] and electrode screw rod [4] can step size.The electrode of lower panel end maintains static, and can directly the tape test conductor be placed on the electrode of lower panel end [A, B, C].At first with electrode screw rod [4] backspin, make its lower end touch conductor to be measured, revolve on then, on the distance of revolving be electrode separation.This device can be controlled at the interval error of two end electrodes in the 0.01mm.This design has comparatively ideally solved electrode separation control problem.
In operating process of the present invention, in order to get rid of the possibility of other maloperations, in electrochemical treatment process, also can monitor everywhere electric current, voltage with electric current, voltage tester table (such as universal electric meter) at any time, be in set condition to guarantee each electrochemical treatment conditional stability ground.
Device of the present invention, simple in structure, easy to operate, accurately control electrode spacing and power supply output can realize repeating, regulatable nano bubble preparation, and can estimate exactly its anti-soil effect.
