The so-called "steel-plastic composite structure" means that the outer layer of this storage device is made of steel to achieve stability, and the inner layer is made of plastic liner made of special technology. Its advantages lie in avoiding the particularly active reaction between metal shipping equipment and hydrochloric acid, liquid alkali and other chemical properties, reducing the impact on chemicals and improving the safety factor.
The so-called "chemical tankers" refer to some ship types belonging to the category of chemical tankers in the shipping industry, among which chemical tankers capable of transporting high-risk goods such as hydrochloric acid and liquid alkali are the first-class ship types in this category, and their requirements are more stringent. Inspection by ship inspection departments and classification societies at home and abroad is extremely strict, from drawings to construction to completion of construction, and even to launching test and monitoring after normal operation.
At present, the research, development, design and construction of this multi-compartment steel-plastic composite structure ship at home and abroad have just started, which is the dream achievement of many ship design institutes, because there is no inspection experience and standard for this chemical ship at home and abroad. Secondly, with the increasing proportion of China's economy and shipping industry in the world, the market for transporting dangerous chemicals (such as hydrochloric acid and liquid alkali) is very broad. Third, most shipping companies at home and abroad have chemical tankers.
It is understood that after 3-4 years of land transportation test, only the Far East Ship Design and Research Institute in Hangzhou, China has designed this chemical ship, which is the first such ship in the world. And passed the approval of China Classification Society (CCS). While many ships have entered the construction stage, China ship science and technology enterprises have also become the leaders of the world industry standards in this field.
This type of ship has great development space in many industrial fields such as chemical industry, biology, dyestuff, medicine, pesticide, metallurgy, rare earth, machinery, electroplating, steel, automobile, environmental protection, textile, brewing, water supply, drainage, logistics, chemical liquid storage and so on. It can sail in China's offshore routes, coastal routes, direct flights between rivers and seas and inland river systems.
