Abstract

The invention provides a corrosion prevention method for a margin plate of a storage tank. The corrosion prevention method comprises the following steps: coating butyl viscoelastic body corrosion-prevention paste on an overlapped part of the margin plate and a base platform; and coating a silicone corrosion-prevention sealant on the margin plate and the butyl viscoelastic body corrosion-prevention paste to form an elastic seal. The corrosion prevention method adopts an elastic connection and sealing manner of combining the silicone corrosion-prevention sealant with good atmosphere aging resistance, great displacement capability and good bonding performance, and the butyl viscoelastic body corrosion-prevention paste with low water vapor penetration rate; the corrosion on the margin plate by the external environment can be effectively isolated; and meanwhile, the margin plate is simple in structure, convenient to construct, wide in applicable range and long in service life.

Description

technical field [0001] The invention relates to an anti-corrosion technology, in particular to an anti-corrosion method for edge plates of storage tanks. Background technique [0002] With the rapid development of the national economy, the number of various types of storage tanks in our country has increased several times, and the reserves have increased, resulting in an increasing load on the storage tanks, and the frequency of oil leakage caused by corrosion of the storage tanks has increased relatively. According to the analysis of relevant survey data, in the storage tank corrosion, the bottom plate corrosion accounts for 80%; in the bottom plate corrosion, the corrosion under the bottom plate accounts for 50%; in the bottom plate corrosion, the corrosion under the edge plate accounts for 60%. It can be seen that the corrosion of the edge plate of the bottom plate is one of the main reasons for the failure of the storage tank. In fact, the survey statistics are lower tha...
