“Submarine hydrothermal sulfide†is a seabed deposit that is receiving increasing international attention. Since 1997, the China Ocean Association organized “Dayang No. 1†and the “Marine No. 4†of the Guangzhou Marine Geological Survey Bureau to conduct a survey and research on seabed resources for nine voyages. Recently, "Dayang No. 1" set sail from Qingdao on April 2, 2005, and executed China's first global ocean science examination task. It plans to work at sea for about 300 days. In January 2006, it returned to Qingdao. One of the main purposes. It is to explore the seafloor hydrothermal sulfide. As early as 1991, China was approved by the United Nations as the fifth deep-sea mining pioneer investor, undertaking the exploration mission of 300,000 square kilometers of ocean floor, and eventually possessed the priority mining rights for the 75,000 square kilometers of mineral resources with the most abundant mineral resources. Fissures into the ground water from the earth's crust, is heated lava encountered, the water discharged from the dissolving subterranean formation surrounding the gold, silver, copper, iron, zinc, lead and other metals. These metals undergo chemical reactions to form sulfide deposits on nearby seabeds, forming massive seabed deposits ranging from several thousand tons to hundreds of millions of tons. The submarine hydrothermal activity also forms a strange landscape like a chimney. Around the "chimney", living with high temperature and high temperature resistant biomes, their unique biological characteristics also have broad application prospects. At present, developed countries attach great importance to relevant research. In the central trough of more than 2,000 meters deep in the Red Sea, marine scientists discovered the famous "hot brine sediment", which is actually called hydrothermal sulfide. According to preliminary estimates, only the hydrothermal sulphide in the Red Sea has 24 million tons of iron, 1.06 million tons of copper, zinc and associated 2.9 million tons of lead, silver and gold.
According to the relationship bewteen Paper Making Machine and coating machine, this series of paper coating machine is divided into online coating machine and offline coating machine. For different applications of coating paper, the coating mode is divided into single-side coating and double-side coating, each side can be coated one or more times. The coating machine is mainly uses air knife coater and blade coater, consisting of unwind system, coater, drying system, gloss calender system, regulating and finishing, reeling section and transmission system etc.
