& nbsp; & nbsp; Glue varies depending on its usage. Below, structural glue manufacturers will share with you& nbsp;< br />


  & nbsp; & nbsp; Use classification

  & nbsp;& nbsp; & nbsp; 1. Structural repair adhesive is used to repair small surface defects and ensure local flatness of the adhesive< br />
  & nbsp;& nbsp; & nbsp; 2. Interface agents and primers are used to increase the bonding strength between new and old concrete joints in load-bearing structures< br />
  & nbsp;& nbsp; & nbsp; 3. Adhesive used for injecting cracks in concrete and masonry components< br />
  & nbsp;& nbsp; & nbsp; 4. Plant structural adhesive on different substrates, such as steel bars, bolts, and chemical bolts< br />
  & nbsp;& nbsp; & nbsp; 5. A structural adhesive used to bond steel and composite fibers onto different substrates< br />


  & nbsp; & nbsp; Classification of service life of structural adhesives

  & nbsp;& nbsp; & nbsp; The service life can be designed within a set range based on its main adhesives, curing agents, modified materials, and other additives. The commonly used steel structural adhesive is generally designed for a service life of 30 years. Therefore, in the design and construction process of steel reinforcement, structural adhesive should undergo special inspection and identification in the design specifications< br />


  & nbsp; & nbsp; Structural adhesives classified by temperature and humidity

  & nbsp;& nbsp; & nbsp; 1. High humidity surface (underwater) curing type (III). It is suitable for on-site curing from -45 ℃ to 125 ℃< br />
  & nbsp;& nbsp; & nbsp; 2. Low temperature curing type, suitable for on-site curing from -45 ℃ to 95 ℃< br />
  & nbsp;& nbsp; & nbsp; 3. Room temperature curing type, suitable for on-site curing from -45 ℃ to 65 ℃< br />


  & nbsp;& nbsp; & nbsp; Classified by adhesive substrate

  & nbsp;& nbsp; & nbsp; 1. Wood base. It will be applied to structural adhesives to strengthen wooden components< br />
  & nbsp;& nbsp; & nbsp; 2. Steel base. Used for structural adhesive fixation of steel components< br />
  & nbsp;& nbsp; & nbsp; 3. Masonry foundation is used for fixing masonry components with building adhesive< br />
  & nbsp;& nbsp; & nbsp; 4. Concrete foundation. That is to say, structural adhesive will be used to fix concrete components< br />
