2022-07-07
Although hot melt adhesive is widely used for many industries, even in our daily life. But many people still have doubts about the adhesion of hot melt adhesives. When the material is compounded, the hot melt adhesive is not firmly degummed or non-stick. Generally speaking, it can be analyzed from the following. 1. There may be problems with the raw hot melt adhesive materials If it is caused by quality problems, it is necessary to investigate the relevant responsibilities from the supplier. When purchasing again, choose a manufacturer with strength and quality that can be guaranteed. 2.Degumming or non-sticking caused by incompatibility of hot melt adhesive and material Check to see if due to the type of hot melt being used that is not compatible with the material being compounded. If it is caused by the compatibility of materials, it is only necessary to re-select hot melt adhesives that are compatible with materials. For the user, it is very important to do a good job of testing and proofing before mass production 3. Degumming or non-sticking caused by insufficient weight or thickness of hot melt adhesive If it is not due to material compatibility, it is possible that the composite material too thick, and the hot melt adhesive is too thin or the gram weight is too small, resulting in insufficient bonding strength. In this case, change to larger thickness hot melt adhesive or a heavier gram can be used to solve this problem. 4. Degumming or non-sticking caused in laminating process Wrong operation is the normal reason, it is better to do pre-job training if it is caused by it. Apart from the above, It may also be caused by equipment. In order to avoid the situation that the hot melt adhesive is not sticky, it is necessary to do a good testing and proofing before mass production. Jiangmen M.F.B.S.
