BAIJIAN - Third party testing organization
Testing Introduction: Adhesive: Suitable for various metal materials such as aluminum、 steel、 iron、 copper、 etc; Glass、 wood、 concrete and other non-metallic materials; And thermosetting plastics such as phenolic、 amino、 unsaturated polyester、 etc. have excellent adhesive properties、 hence they are called universal adhesives. The Technical Specification for Safety Appraisal of Engineering Structural Reinforcement Materials GB50728 has testing requirements for adhesives. Testing scope: chloroprene adhesive、 single component flame-retardant chloroprene phenolic adhesive、 special adhesive for EPDM waterproofing membrane、 environmentally friendly adhesive、 special adhesive for shield tunnel sealing pad、 chloroprene phenolic adhesive、 cement-based adhesive、 modified vinyl ester adhesive、 epoxy adhesive for prefabricated section assembly、 epoxy adhesive、 structural adhesive Testing items: non volatile matter content Adhesion in shear state: Coiled substrate: Standard test conditions、 Adhesion in shear state: Coiled substrate: Retention rate after heat treatment、 Adhesion in shear state: Coiled substrate: Retention rate after alkali treatment、 Shear strength of bonding surface (rubber and cement)、 Non volatile matter content、 Colloidal properties: Tensile strength、 Positive tensile bonding strength with concrete、 viscosity、 peel strength、 free formaldehyde、 benzene、 dichloromethane Total volatile organic compounds、 adhesive butt joint tensile strength、 etc
