Use cotton yarn to remove dust, oil stains, and visible water from the surface of the sealed area. If there is easy peeling and rusting on the surface, it should be cleaned with a metal brush in advance. If necessary, organic solvents such as alcohol and acetone can be used to wipe the surface. According to the shape of the construction site, the tip of the sealant should be cut into a certain shape and size, and the sealant should be manually or pneumatically applied to the construction site. Surface scraping, decoration and other work should be carried out within the surface drying time. For areas with particularly strict surface requirements, protective tape should be applied on both sides of the adhesive coated area and removed after scraping off.

If the seal accidentally stains non construction areas, it can be wiped clean with a cotton cloth dipped in alcohol. After opening, it should be used up on the same day, otherwise it needs to be strictly sealed and stored. Shanxi seals are best constructed under conditions of temperature 15-35 ℃ and humidity 55% -75% RH. When the ambient temperature is below 10 ℃ or the glue dispensing speed does not meet the process requirements, it is recommended to bake in a 60 ℃ oven for at least 30 minutes. The quality of the seal directly affects the packaging effect, storage and service life of the packaging, and even the reputation of the packaging. For this reason, sealing glue has become an important component of the packaging field. According to the form and usage of sealing materials, they can be roughly divided into three categories: gasket sealing, tape sealing, and gel sealing, all of which can prevent liquid leakage, block oxygen, moisture, and odors from entering, and prevent counterfeit and inferior products. Anti counterfeiting sealing is a packaging sealing technology that has emerged in recent years, generally using hot melt adhesive point sealing or pressure-sensitive tape bonding.
