Ocean monitoring equipment is the marine survey, observation and an important tool for marine scientific research, these machines use a lot of light, sound, electricity, chemical and biological sensors, such as [1 - 3]. However, marine fouling organisms in these sensitive components of machines the surface of a small amount of biological device can be attached to the work of destruction, resulting in transmission equipment failure, signal distortion, the decline in performance, such as shortening the life of serious harm. As ocean monitoring brass ball valve equipment itself is expensive, sometimes the value of their data in far more than the value of the equipment itself, so prevention of marine biological attachment (pollution) is the long-term operation of ocean monitoring equipment and access to accurate and reliable data and an important guarantee.
At present, marine monitoring equipment used in the anti-pollution technology are: anti-fouling coatings, anti-fouling materials (such as copper alloy), mechanical methods (such as electric brush), electrochemical methods (electrolytic copper around the sensor) [4 ]. Tushua anti-fouling coatings which is the most extensive application, a most effective anti-pollution technology and facilities at home and abroad in the structure of the use of anti-fouling coatings have many mature products, those products mainly in Wuxi since the anti-fouling paints for polishing Lord, and a new environmentally friendly non-toxic anti-fouling paints are also exhibited an increasing trend of development [5 - 6].
The implementation of attachment and biological coating technology is a prerequisite for its good control of attachment without affecting the ability of the various sensors for measuring performance and indicators. According to the structure of marine monitoring equipment characteristics, ocean brass ball valve monitoring equipment attached to the biological components can be broadly classified into four categories: transmission structure, optical devices, the shell surface, the sensor (surface or pathway). Clearly, they need the protective coating is different in nature. Transmission of protective coating should have a quality of light, resistant to erosion, strong adhesion characteristics of optical devices protective coating must be transparent; shell coating the surface anti-pollution ships and the requirements of anti-fouling paints used similar sensors (surface or pathway) Protective coating paint process and the need to consider the monitoring parameters of [7]. Marine pollution monitoring equipment is a more complex project, involving marine chemistry, material sciences, biology, and other disciplines, so far, has not been defaced can effectively resolve the biological products.
This article in the current domestic and foreign research of existing anti-pollution technology on the basis of eight selected from the most representative of the anti-fouling paints (No. C 1 ~ C 8), copper alloys, ceramics and antibacterial self-developed anti-pollution Material (transparent anti-fouling coatings, anti-fouling Central) as the study. As a wide variety of marine monitoring equipment, the structure of complex, expensive, in order to solve its practical application in specific anti-pollution problem, we designed a variety of different components to simulate the ocean monitoring equipment of key components, and inspection of various anti-fouling materials brass ball valve in these Components on the actual performance of sea pollution, for screening and monitoring of marine equipment suited to the material structure, and without prejudice to the device measuring the performance of low toxicity, long-term, broad-spectrum anti-pollution technology to provide the basis. brass ball valve |
