As we all know, the structure of a thermal power plant must withstand the test of high temperature. Although the place where the reinforcement is strengthened will not be inside the boiler, we still need to pay attention to the choice of high temperature resistant planting bar adhesive under this specific place.
In the field of maintenance, reinforcement and transformation of concrete structures in thermal power plants, epoxy high temperature resistant planting bar adhesive is widely used due to its advantages of good mechanical properties, convenient construction, short reinforcement period and cost saving. As an organic polymer material, the heat resistance of epoxy building high temperature resistant planting bar adhesive should be paid enough attention. For the heat resistance of organic high temperature resistant rubber, people are most concerned about the strength and deformation resistance of the material at a certain temperature, and the resistance of the material is characterized. Two important temperature indicators of deformation performance are heat distortion temperature (HDT) and glass transition temperature (Tg). The heat distortion temperature test method is simple and widely used in engineering.
For the first time, the heat distortion temperature of the "Technical Specification for Safety Evaluation of Engineering Structure Reinforced Materials" (GB 50728-2011) (referred to as the material specification) has specified the heat resistance of high temperature resistant planting bar adhesive, which requires the the heat distortion temperature (B method) of I-type high temperature resistant planting bar adhesive that uses concrete as the substrate is not lower than 65 ° C under the condition of solidification of 23 ° C for 21 d. The room temperature curing building high temperature resistant planting bar adhesive is required to meet the basic mechanical properties while taking into account the indexes of heat resistance, toughness and viscosity. It is difficult to achieve by reasonably selecting the components of the high temperature resistant planting bar adhesive.
These standards seem to be difficult to achieve. In fact, all of Mankate's high temperature resistant planting bar adhesive can achieve them. Mankate Technology's high temperature resistant reinforced adhesive has good temperature resistance and can be used in 135° environment for a long time. Even short-term high temperature resistance can reach 200°. It has good solder resistance and flame retardant performance. There is almost no shrinkage during the curing process. It is very suitable for being used in some specific environments such as thermal power plants. In fact, important large-scale projects such as Tianwan Nuclear Power, Suzhou Metro, Kunyu High-speed Railway, and Shanghai Disney have been applied.
