We provide zinc anode can be used in ships, port facilities engineering, marine engineering, buried metal pipes, tanks, sea water cooling water system cathodic protection of steel structures. Zinc alloy sacrificial anode according to national standard GB/T4950-2002 "Zn - Al - Cd alloy sacrificial anode" production, for pipe anode also comply SY/T0019-97 "Buried Steel Pipeline Cathodic Protection design specifications." ◎ Zn - Al - Cd alloy sacrificial anode bracelet style ◎ ◎ ribbon zinc alloy sacrificial anode zinc alloy sacrificial anode corrosion technology in recent years, our country has been rapid development, especially in cathodic protection technology has been widely used in Hong Kong industrial facilities, marine engineering , buried pipelines, household appliances and petrochemicals, power, coal, municipal, surrounded by other fields; for the country to restore a large number of economic losses, has made very significant economic and social benefits. I produced for use in the field of cathodic protection sacrificial anode products have the following three series of a dozen varieties and hundreds of specifications. Zinc anode chemical composition consistent US MIL-A-18001H and the ASTM-B418 (Type 1) Standard Zinc alloy sacrificial anode chemical composition: Chemical elements Al Cd impurities, is not greater than Fe Cu Pb Si Zn content% 0.3-0.6 0.05-0.12 0.005 0.005 margin 0.006 0.125 Zinc alloy sacrificial anode electrochemical performance: Performance Type Indicator open circuit potential-V (SCE) working potential-V (SCE) Actual capacity A? h / kg dissolved state current efficiency% -1.09 ~ -1.05 seawater -1.05 ~ -1.00 ≥ 780 ≥ 95 corrosion products are easy to fall off, the surface uniformly dissolved zinc anode: zinc alloy sacrificial anode for short, also known as zinc sacrificial anodes, zinc alloy anode. For the cathodic protection system is to prevent electrochemical corrosion of important equipment and materials. Zinc alloy sacrificial anode for seawater, freshwater and seawater medium ships, ballast tanks, machinery and equipment, marine engineering and port facilities, drilling platforms, ports, seawater condenser water pumps and low resistivity soil pipe , cables and other facilities cathodic protection of metal corrosion. Hong Kungong company specializes in the production of zinc anodes (zinc alloy sacrificial anode). Zn - Al - Cd alloy sacrificial anodes. Major products categories are: 1. Bracelet style (zinc anode) zinc alloy sacrificial anode 2. Ribbon (zinc anode) zinc alloy sacrificial anode 3. Combination (zinc anode) zinc alloy sacrificial anode 4. zinc alloy grounding rods. In accordance with the main purpose of classification 1. Tanks with zinc alloy sacrificial anode 2. Plant with zinc alloy sacrificial anode 3. Pipes with zinc alloy sacrificial anode 4. Marine zinc alloy sacrificial anode 5. Oilfield construction with zinc alloy sacrificial anode 6 port terminal facilities Zinc alloy sacrificial anode. According to the shape can be divided into a lumpy zinc alloy sacrificial anode 2. Cast zinc alloy sacrificial anode 3. Heterosexual zinc alloy sacrificial anode 4 flat iron zinc alloy sacrificial anode and so on. Zn - Al - Cd alloy sacrificial anode Executive Standard: ASTM-B418 / MILA-1800I / J / GB/T4950-2002 Zn - Al - Cd alloy sacrificial anode cadmium zinc aluminum alloy sacrificial anode performance: from the insoluble anode is small, the current efficiency High self-adjusting currents occur anode performance; protection period is longer, up to 20 to 30 years, generally will not happen "over-protection" phenomenon. Zn - Al - Cd alloy sacrificial anode Uses: Suitable for seawater, freshwater and seawater medium ships, machinery and equipment, marine engineering and port facilities, and soil pipes, cables and other facilities cathodic protection of metal corrosion. Zinc alloy sacrificial anodes suitable for hull, ballast tanks and seawater platform, but also often in the form of a ring for subsea pipelines, are very good results, the company's zinc alloy anode is made of high quality zinc and a variety of ingredients, in order to ensure a greater current output and a long service life.
