The performance of anti-corrosion tapes (especially viscoelastic anti-corrosion tapes) is easily affected by environmental factors such as temperature, humidity, and external forces. Strict environmental control, packaging protection, and operating procedures must be followed before and after storage, transportation, and application to avoid performance degradation or physical damage. During storage, the temperature should be maintained in a dry, well-ventilated environment between 5°C and 45°C. It is strictly forbidden to store near heat sources or below 0°C. Humidity should be controlled between 40% and 70%. Storage in damp, waterlogged, or dew-covered areas is strictly prohibited. It must be kept away from direct sunlight and ultraviolet radiation. Stacking must be done horizontally; vertical or tilted stacking is strictly prohibited. The stacking height should not exceed 1.5 meters or the number of layers indicated on the carton. A 10mm thick EPE board should be placed between each layer, and the bottom layer should be raised at least 30cm using a pallet. Adhesive tape rolls must be kept away from corrosive substances, sharp objects, and heat sources. Unopened tape has a standard shelf life of 12 months and should be stored following a first-in, first-out (FIFO) principle. Inventory tape should be randomly checked monthly for abnormalities such as wrinkles, sticking, or discoloration.
During transportation, control must be exercised in three aspects: packaging protection, transportation environment, and loading/unloading procedures. The tape is already protected with plastic film and cardboard tubes at the factory. For full-case transportation, the packaging must be kept intact to avoid heavy pressure, squeezing, or collisions. When stacking multiple rolls of tape, cushioning foam should be placed between layers, the top covered with a waterproof tarpaulin, and the bottom elevated with wooden blocks to prevent water from accumulating on the truck floor and soaking the packaging. In summer, direct sunlight should be avoided to prevent the temperature inside the truck compartment from exceeding 40°C. In winter, if the temperature is below 0°C, the tape should be wrapped with insulating cotton to prevent low-temperature embrittlement, and transportation should be scheduled for the early morning or late evening when temperatures are lower. Loading and unloading must be done manually with care or by forklift; throwing or heavy pressure is strictly prohibited. Tape rolls must be secured with ropes or baffles inside the truck bed. Tape must not be mixed with heavy objects or sharp items.
During construction, if the ambient temperature is too high (e.g., exceeding 30℃) after the tape arrives at the site, shading and cooling measures must be taken. Before construction, the appearance of the tape must be inspected to ensure it is free from damage, deformation, or contamination. If the tape has been opened but not used up, it must be resealed with the original packaging film (ensuring the viscoelastic layer is not exposed to air) and used within 24 hours; it must not be stored for later use.
