Chinese Society for Corrosion and Protection chairman Chen Zhang believes , ZY series heavy duty coating for its green, low surface treatment, painted with rust , corrosion long time , repair and replace hot-dip galvanizing and other features, to solve the traditional rust the existence of many problems, which greatly improved the quality of the domestic heavy-duty coatings.Masking tape
It is reported that currently obtained DNV " seawater ballast tanks coating protection system " (K-5720) type certification , the implementation of the alternative acceptance criteria , the general requirements in the coating thickness of only 75% ( ie 240 microns under ), the only test indicators all through , and adhesion value reached 7 MPa , 1 times higher than the general requirements ( 3.5 MPa ) , resistance to cathodic stripping 4 mm , only the general requirements ( 8 mm ) of two one minute ; cathodic protection current of 1.55 trillion Ann / square meter, lower than conventional requirements 5 trillion Ann / square meter. The product in harsh corrosive environments seawater ballast tanks Conditions goal life of up to 15 years. It is currently the only one less than the conventional type certification requirements obtained in the case of film thickness .
It is understood that the petrochemical industry requires not only the ability of anti-corrosion paint , chemical corrosion and rust before painting process must be safe and reliable, must not produce sparks and other flammable factors . ZY series not only good corrosion resistance , but without sand blasting during construction , painted directly on rusted steel surface , saving a lot of manpower and production costs.Washi tape
Back in the 1980s , Professor Meng Sheng , Professor Sun Jihong , etc. Dozens of Beijing University research team composed of researchers on the launch of the first generation ZY series of heavy-duty anti-corrosion products and applied to the Qinghai-Tibet railway construction . In 2011, Shandong Headland Group and Beijing Industrial University was founded in Penglai Headland New Materials Co., Ltd , invested more than 70 million yuan of special funds , which lasted three years, successfully developed the second generation of ZY series heavy duty coatings , currently marketed D -type primer, S -type paint the bottom one , G -type finish three series of products covering all areas of metal corrosion . Currently the series has received numerous honors and patents , and is widely used in many fields HAECO ships, roads and bridges , petrochemical , machinery manufacturing , in Iron Mountain Bridge Group , Yanshan Petrochemical , Beijing high-speed large number of national key enterprises, focusing on anti-corrosion construction projects have adopted ZY series of heavy-duty products. After Shandong Blue Sail Chemical Corporation and other companies using the product under harsh conditions , were well received.Sellotape
