The seal uses cotton yarn to remove dust, oil and open water from the surface of the glued part.If the surface is easy to peel off and corrode, it should be removed 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 is cut into a certain shape and size, and the glue is applied to the construction site with a manual or pneumatic glue gun, and the surface is scraped and modified within the dry time.Areas with particularly strict surface requirements should be marked with protective tape on both sides of the glued area and removed after scraping.　　

If the seal is accidentally contaminated with non-construction parts, it can be wiped clean with a cotton cloth dipped in alcohol.It should be used up within two days after opening, otherwise it needs to be strictly sealed and stored. It is best to construct at a temperature of 15-35℃ and a humidity of 55%-75%RH. When the ambient temperature is lower than 10℃ or the glue 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 sealing directly affects the packaging effect, the storage and life of the packaging, and even the reputation of the packaging.To this end, sealing glue has become an important part of the packaging field. According to the form and use of sealing materials, it can be roughly divided into three categories: gasket sealing, tape sealing and colloidal sealing. They can all achieve the purpose of preventing liquid leakage, blocking the entry of oxygen, moisture, and odors, and preventing forgery and shoddy products. Anti-counterfeiting sealing is a packaging sealing technology that has emerged in recent years. It is generally sealed with hot melt adhesive or pressure-sensitive tape. Once the packaging is folded, it will not be able to return to its original state, which can prevent the appearance of shoddy products and protect the interests of consumers.
