高电位镁合金牺牲阳较保护价格低

High potential magnesium alloy sacrifice anode protection low price

 高电位镁阳较的均匀电流输出不会受到干扰主要是因为他的阳较较化比较小，铁、同和镍杂质成分增加了阳较的局部腐蚀，这样就减少了他的寿命，镁阳较主要用在电阻率土壤P≤100Ωm的地下装置中，带状的镁阳较用在P≤150Ωm的范围内。海水里镁阳较的大输出可以达到1A。镁阳较的阴较保护电流输出给电阻率有关系，优点是：阴较保护的铁面比较，电位差大，缺点：表面不光滑，镁阳较不安全不能放在易爆的地方，效率jin仅约50%。国外还研制乐然埋地装置的高电流镁阳较，杂质比较低，寿命比较长。电位更低约-0.1 V。通过加入钠使合金成分得到类似效果。

牺牲阳较用填料包有何要求？

    填料包的主要作用就是为了降低牺牲阳较的接地电阻，所以要求填料包本身的电阻率尽量要低，不同的牺牲阳较在不同的环境中，其填料包成分比例也有区别，合理的成分及配比是保证低电阻率的保证。填料包的初始电阻率为0.5——0.6欧姆?米，随着渗透不断增加，电阻率可能升高到1.5欧姆?米。这个数值在阴较保护设计中是个注意的参考数据。

In corrosion and protection research, we are committed to the development and dissemination of knowledge. Corrosion is the destruction or deterioration of a material by the environment. Materials include metal and non-metallic materials. Where materials are made, there are problems of different forms and degrees of corrosion. The annual cost of corrosion has exceeded the combined cost of fire, floods, earthquakes and car accidents. Metallic oxide has excellent physical, chemical and electrochemical properties. Because Titanium is used as a substrate, it is easy to process into the desired shape and is light in weight, facilitating processing and installation. Our company produces MMO electrode by using new research party mixed metal oxide anode material. It is highly corrosive in acidic media, and it also takes into account the oxidation of antimony iro2 and extremely high oxygen over potential, and adds iro2 and SnO2, ruo 2, ta2o 5, PDO to form composite metal oxides. Electrodes, metal oxides have shape. .. .. .. .. .. For the built platform, the sacrifice of the underwater installation anode is expensive, and the above fixed type is also too high to be adopted because of the high installation cost. The tension type applied current cathodic protection has both cathodic protection and monitoring functions. The auxiliary anode, reference electrode and cable are integrated into one, which is called a composite cable and has load bearing, supply anode current and transmission monitoring functions. The top of the composite cable is fixed on the platform rod, the bottom is fixed on the basis of gravity, and a certain pre-tension is applied according to the sea conditions to make it in a tensioning state, so it is also called a tensile applied current cathode protection. Gravity infrastructure and weight, composite cable tensioning force and other factors need to be considered to determine the specific conditions, water depth and other factors, and at the same time to ensure that under possible conditions, especially extreme conditions, composite cables and platform structures, and composite cables maintain a certain distance. The structure and length of composite cable, gravity foundation and tension force are closely related. Because the auxiliary anode is evenly arranged vertically, the potential distribution is more uniform and the required protection current is relatively small. This major feature is that it does not require underwater operations during installation, or it only requires simple underwater operations as an aid. Therefore, it is easy to install, and the overall cost is low. It has a great advantage in serving the cathode protection of the active platform.
