Sea splash zone environment experimental simulation system

Abstract

The invention relates to a sea environment experimental system and provides a sea splash zone environment experimental simulation system. The system comprises a test sample bin fixed to a sponge floating platform. The test sample bin is in a hollow cylindrical shape. The end of the test sample bin is in a closed cone shape. The tail of the test sample bin is in an open shape and is provided with a bin opening cover for sealing. A plurality of through holes are formed in the bin wall of the test sample bin along the axial center lines of the top and the bottom and the horizontal center lines of the two sides at intervals. The system is small in size, economical, portable, environmentally friendly, and capable of perfectly simulating the clinical point corrosion phenomenon of the sea splash zone and the seawater total immersion zone. The sea splash zone environment experimental simulation system can simulate sea corrosion behaviors of materials and components in an accelerated mode in various sea corrosion factor environments, and research on the corrosion rules, evaluation of the durability performance and the like of the materials and the components in the sea splash zone and the seawater total immersion zone critical point corrosion zone can be conveniently performed.

Description

Technical field [0001] The invention relates to a marine environment experiment system, in particular to an environment experiment simulation system of a marine splash zone. Background technique [0002] my country vigorously develops marine resources, develops marine economy, and peacefully uses and protects the ocean is an important national policy. In recent years, extensive development of marine resources and the construction of marine transportation infrastructure, these facilities are usually made of steel structures or reinforced concrete structures. Since the ocean is a very harsh corrosive environment, the economic loss caused by corrosion accounts for 3-5% of the gross domestic product (GDP) every year. From the perspective of corrosion, due to the periodic wetting of the seawater, the surface of the metal structure has been in a state of alternating dry and wet for a long time. The oxygen supply is sufficient, the salt is continuously concentrated, plus the temperatur...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional salt spray corrosion instrument, salt immersion corrosion instrument, etc., due to the single and relatively static simulated marine corrosion factors, have a large gap with the environmental characteristics of the real marine tidal zone, and cannot provide reasonable preliminary research data support for marine corrosion tests.

Few people have done research on the corrosion of the critical point between seawater and the atmosphere, and there is no suitable research method. This test combines the critical point of the oceanic seawater splash zone and the seawater full immersion zone with the platform of the accelerated simulation system platform of the seawater splash zone. The experimental device designed for
