Use cotton yarn to clean the dust, oil and water on the surface of the glued part of the seal. If the surface is easy to peel off and rust, it should be removed in advance. If necessary, you can also wipe the surface with organic solvents such as alcohol and acetone. According to the shape of the construction part, cut the tip of the sealant into a certain shape and size, and manually apply the glue to the construction part , Carry out surface leveling and modification work within the surface drying time. The parts with particularly strict surface requirements should be covered with protective tape on both sides of the glued part, and peeled off after scraping.
If the non-construction part of the seal is accidentally contaminated, it can be wiped clean with a cotton cloth dipped in alcohol. It should be used up within days after opening, otherwise it needs to be strictly sealed and stored.
The construction is best under the conditions of temperature 15-35℃ and humidity 55%-75%RH. When the ambient temperature is lower than 10℃ or the glue output speed does not meet the process requirements, It is recommended to bake for at least 30 minutes in an oven at 60°C. The quality of the seal directly affects the packaging effect, the storage and life of the packaging, and even the reputation of the packaging.
For this reason, sealant has become an important part of the packaging field. According to the form and use of the sealing material, it can be roughly divided into three categories: gasket seal, tape seal and gel seal, all of which can prevent liquid leakage, block oxygen, and moisture. The purpose of anti-counterfeiting and anti-counterfeiting products, anti-counterfeiting sealing, is the packaging and sealing technology that has emerged in recent years. Generally, hot-melt adhesive dot sealing or pressure-sensitive tape sealing is used. Once the package is dismantled, it cannot be restored to its original state. Fake and inferior products appear to protect the interests of consumers.
