Why doesn’t hot melt glue stick? It can be analyzed from the following four aspects:
1. There may be problems with the quality of the purchased hot melt adhesive
If it is caused by quality problems, you must find the corresponding supplier for accountability. When purchasing again, please choose a hot melt adhesive manufacturer with strength and quality assurance.
2. Debonding or non-sticking due to incompatibility of hot melt adhesive with material
Check for incompatibility with the type of hot melt used for the composite. If it is caused by the compatibility of the material, you only need to re-select the hot melt adhesive that is compatible with the material. It is very important for users to test and proofread well before mass production!
3. Degumming or non-sticking caused by insufficient gluing weight or thickness of hot melt adhesive
If it is not due to degumming and non-sticking caused by material compatibility, it may be that the thickness of the hot melt adhesive is too thin or the gram weight is too small, resulting in insufficient bonding strength. This situation can be solved by the thickness of the hot melt adhesive.
4. Degumming or non-sticking caused by improper operation in the construction process
Degumming or non-sticking caused by improper operation during the construction process is a relatively common cause. If it is caused by improper operation of the production line, pre-job training is recommended
In addition to the above four aspects, it may also be caused by construction equipment. Although this possibility is not very high, it still needs to be considered. If you want to avoid hot melt adhesive not sticking in use, you must do a good job of testing and proofreading before mass production.
