A method for improving the forming quality of two-component epoxy resin adhesive strips for lng ships

Abstract

The invention discloses a method for improving the LNG carrier dual-component epoxy resin adhesive tape shaping quality. The method comprises the following steps that firstly, an epoxy resin main agent charging basket and a hardening agent charging basket are stored for two days, secondly, a heating unit is arranged on the charging baskets, an energy accumulator is arranged on a metering system, an energy accumulator monitoring device is arranged on the energy accumulator, then, the two agents are mixed and matched for testing, the epoxy resin mixed adhesive hardness is tested, and finally a sample strip is punched, and whether the production requirement is met or not is detected. Before coating work is performed, the epoxy resin main agent and the hardening agent are preheated, the raw material mobility can be improved, the raw material viscosity is lowered, the dual-component epoxy resin adhesive tape shaping quality is ensured, the service life of an internal sealing ring and otherquick-wear parts is prolonged, the epoxy resin main agent and hardening agent dosage is greatly lowered, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of large-scale LNG ship construction, in particular to a method for improving the forming quality of two-component epoxy resin rubber strips for LNG ships. Background technique [0002] The LNG carrier is known as the "crown jewel" of the world's civil ships. Its liquid cargo containment system, liquid cargo barge system and special power propulsion system constitute the three major characteristics of the LNG carrier. Among them, the liquid cargo maintenance system is the most special area of ​​the entire LNG ship, and it is also the most difficult part of design and construction. [0003] The liquid cargo containment system of an LNG carrier is mainly composed of two layers of insulating boxes and two layers of invar steel to isolate LNG from absorbing heat from the cargo tank, and at the same time transmit the pressure of the liquid to the bulkhead to ensure that the LNG will not leak. Therefore, LNG ship...
