Embodiment Construction

[0028] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0029] The present invention provides a technical solution: a rust removal and anticorrosion method for a steel structure of an integrated offshore mining and repair platform, comprising the following steps:

[0030] S1. Material preparation stage: Check whether the different batches of paint and thinner to be used are produced by the same manufacturer. When there are raw materials to be used from different manufacturers, it is necessary to confirm whether they can be used together under the guidance and approval of professionals. The paint and thinner pass Physical and mechanical properties and targeted corrosion resistance tests, the performance meets the design requirements before it can be used. At the same time, each batch of paint must be sampled and sent to the relevant department or testing department for inspection before use, and the inspe...

Abstract

The invention discloses a rust removal and corrosion prevention method for an offshore mining and repairing integrated platform steel structure, and belongs to the technical field of offshore rust removal and corrosion prevention. A good mutual matching effect among raw materials can be guaranteed by inspecting coated materials in the coating process, through follow-up pretreatment and secondary treatment on the surface of steel via matching, the surface of steel can be kept clean, different cleaning standards are adopted for treatment according to different thicknesses of different steel profiles, the quality of later coating is guaranteed, a layer of workshop primer of inorganic zinc silicate is sprayed in a mechanical automatic airless spraying mode before coating, the later coating spraying and protection effects are further improved, the later coating process is more convenient through the pretreatment of a corresponding weld joint, the exposure of a protruding part after the coating is avoided, and the later coating quality can be guaranteed and the coating can be kept more convenient and standardized through the mode.

Description

technical field [0001] The invention belongs to the technical field of rust removal and anticorrosion at sea, in particular to a rust removal and anticorrosion method for a steel structure of an integrated offshore mining and repair platform. Background technique [0002] The integrated offshore mining and repairing platform is mainly used for offshore structures of drilling wells. Equipment for the integration of bodywork, procurement and repair, power, communication, navigation, etc., as well as safety and lifesaving and personnel living facilities. An indispensable means of offshore oil and gas exploration and development. There are mainly jack-up and semi-submersible mining and repairing integrated platforms. The operating environment of marine mining and repairing integrated platforms is extremely harsh, such as sunshine, sea breeze, wave impact, complex seawater system, diurnal and seasonal temperature changes, and marine biological erosion. The corrosion rate of off...
