What material should choose through the sea of soft rubber joints.
Soft rubber joints according to different rubber formula, can be divided into multiple, commonly used are: neoprene joint, joint epdm, nitrile butadiene rubber joint, butadiene rubber joints, etc.The neoprene joint has good corrosion resistance, and good flexural resistance and permeability, can be made into diaphragm and vacuum seal products or in a flexible rubber joint.
The sea is a very complex multicomponent aqueous solution.All sorts of elements in seawater with certain physical and chemical form.The form of the copper in seawater is relatively complex, most of the organic complex forms exist.In only a small part of free ions in most are in form of bivalent cation, anion appear complex.So free copper ions dissolve accounted for only a small part of the copper.Water content is extremely rich in sodium, but its chemical behavior is very simple, it is almost all exist in the form of Na + ions.Dissolved organic matter in the sea water is very complex, is primarily a called "Marine humic substance, its properties and vegetation decomposition generated in the soil humic acid and rich similar sensitive acid.The molecular structure of the Marine humic has not entirely sure, but it has to do with strong metal can form complex.
Because the water is corrosive, so should need rubber joint is corrosive.Good corrosive made into the chloroprene rubber joint, can be widely used in various sea areas.So should be made from neoprene rubber joint.
