Abstract
The method to control metal surface attaching microbe film is characteristic in that: starting the constant potentiometer to cathodic polarize the metal device to 0.8V vs.SCE; timed breaking and starting the ultrasonator to device, reducing microbe attaching speed with cathodic polarization; when there much attaching microbe, removing generated microbe film with said ultrasonator. Wherein, connecting the out auxiliary electrodes of the ultrasonator to feed terminal C of potentiometer and feed terminal R of reference electrode; connecting the output line of ultrasonic controller to input terminal of ultrasonator. This invention can kill surface microbe and control attaching speed, controls film forming and further biodefilement, and realizes auto timed cleaning.
Description
Technical field
The present invention relates to a kind of method of metallic surface attached microbial film and used device controlled.
Background technology
Hardware in the ocean environment can form one deck microbial film rapidly usually, various marine lifes will take place subsequently on this basis adhere to, and makes the stability of hardware and serviceability be subjected to very big influence, even disablement.Therefore, need take the microorganic adhesion measure of control.Now use mechanical removal method, sterilant method and antifouling coating method usually.Mechanical removal method efficient is low, and cost is high and not thorough, seldom uses.Owing to current environmental protection requirement is improved year by year, the use of sterilant and antifouling coating also is subjected to increasing restriction.
Summary of the invention
The purpose of this invention is to provide a kind of method of metallic surface attached microbial film and used device controlled, it can remedy the above-mentioned deficiency of prior art.
A kind of method of controlling metallic surface attached microbial film; it is characterized in that opening earlier potentiostat; hardware to be protected is carried out cathodic polarization to 0.8V vs.SCE; equipment oriented is fixed time to disconnect and is opened ultrasonator then; with cathodic polarization microorganic adhesion speed is reduced, treat the microbial film that the more back of microorganic adhesion has produced with the regular removing of ultrasonator.
Implement the used device of aforesaid method, it is characterized in that having a ultrasonator, the supporting electrode the when stainless steel plate of its outside polarizes with the protection equipment of opposing, this supporting electrode is connected to the supporting electrode input terminal C and the reference electrode input terminal R of potentiostat; The output line of ultrasonic controller is connected to the input terminal of ultrasonator.
The present invention is loosening and removing microbial film with the mechanical vibration of ultrasonic generation; utilize the electrochemistry cathodic polarization to kill surface microorganism simultaneously and controlling microbial is adhered to speed; microorganism can't be adhered to and breed in that equipment surface is stable, protect the hardware long-term stability in briny environment, to move.Ultrasonic vibration is interrupted to be used, and can keep the removing effect of microbial film, reduces energy consumption simultaneously again.The cathodic polarization power consumption is very low, can use continuously, can reduce microorganic adhesion speed again.Formation that so just can the long-term control microbial film and the further generation of biodeterioration, the elimination efficiency height does not pollute environment, can realize regularly removing automatically.
Description of drawings
Accompanying drawing is an apparatus structure synoptic diagram of the present invention.
Embodiment
Device of the present invention has a ultrasonator 1, the supporting electrode 5 the when stainless steel plate of its outside polarizes with the protection equipment 4 of opposing, and ultrasonator 1 is used to produce ultrasonic wave.This supporting electrode 5 is connected to the supporting electrode input terminus C and the reference electrode input terminus R of potentiostat 3; The output line of ultrasonic controller 2 is connected to the input terminus of ultrasonator 1.During use; hardware 4 to be protected is wired to the working electrode output terminal W of potentiostat 3 in the seawater; open potentiostat 3 then; be adjusted to two electrodes and can both carry out the strong attitude of polar; hardware to be protected 4 is carried out cathodic polarization to 0.8V vs.SCE; equipment oriented 4 is fixed time to disconnect and is opened ultrasonator 1 then, by seawater 6, makes microorganic adhesion speed reduction on the hardware 4 with cathodic polarization.Treat the microbial film that the more back of microorganic adhesion has produced with ultrasonator 1 regular removing.
Microorganic adhesion is a kind of intensive spontaneous process, also is one and is difficult to comprehensively the thoroughly difficult problem of solution so far.Method provided by the invention does not produce environmental pollution, and consumed energy is low, and span of control is wide, and can realize operation control automatically according to field condition, is a kind of method that has wide application prospects.
