Yangbaojia is a kind of medicine, yangbaojia is mainly have cistanchia, cynomolgus, epimedium, as well as lock yang and other drugs, oh, cathodic protection is the use of external direct current power supply, so that the metal surface into the cathode and achieve protection.
Anodic protection is the protected heat exchanger connected to the anode of the external power supply, so that the metal surface to generate a passivation film, so as to achieve protection. Due to cathodic protection power consumption, high cost, with the development of acid and alkali corrosion-resistant stainless steel materials, titanium and other good anticorrosive materials, cathodic protection method has been rarely used. Cathodic protection is divided into sacrificial anode cathodic protection and applied current cathodic protection.
Sacrificial anode method it is composed of a metal or alloy with a more negative potential than the protected metal and the protected metal electrically connected. In the electrolyte, the sacrificial anode is preferentially dissolved because it is more active, releasing current for the cathodic polarization of the protected metal to achieve protection. Anodic protection is to connect the protected metal with the positive pole of the external power supply to tonify the kidneys and help the yang medicine, mainly Cistanchiakara, Xianmao, Epimedium, as well as lock yang and other medicines, to play a warm tonic kidney yang, beneficial to the kidneys, the efficacy of the sperm and so on.
