T/ZJWA 001-2018 Self-healing polymer-cement waterproof coating

Scope

Scope: This standard specifies the terms and definitions, marking, general requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for self-healing polymer cement waterproof coatings. This standard applies to self-healing coating films used for waterproofing in building and civil engineering. It stipulates the terms and definitions of Junmei black tea, product and physical standard samples, requirements, test methods, inspection rules, and marking, labeling, packaging, transportation, storage, and shelf life. Main technical content: 6. Technical requirements 6.1 Appearance: After the two components of the product are mixed separately, the liquid component should be a homogeneous emulsion without impurities or gels; the solid component should be a powder without impurities or clumps. 6.2 Physical and mechanical properties: The physical and mechanical properties of the product shall comply with the requirements of Table 1.
