Will the hot melt adhesive film melt in summer

Hot-melt adhesive film is a hot adhesive that can be a solid with casting hot fusible film  stable performance at room temperature and does not have adhesive force! But the condition for adhesive force is to heat it, and then it will have a melting point when it reaches the corresponding temperature. At that time, after it melts, it is cooled to achieve the effect of bonding the article, so that it can be sure that the hot melt adhesive film needs to be heated before it can melt.

It is this condition that the hot melt adhesive film needs to be heated and melted, which makes some customers worry about whether the hot melt adhesive film will melt in summer. The editor can tell you with certainty that hot melt adhesive film will not melt in summer. The melting of the hot melt adhesive film only occurs after heating to the corresponding temperature. The melting point of the hot melt adhesive film is usually above 90 degrees, and the lower melting point is 80 degrees.

Although the summer is very hot and high temperature, it is far from the temperature that can melt the hot melt adhesive film. Adhesives are used in repairing broken mechanical parts. The broken mechanical parts cannot be welded. The adhesive bonding method can achieve strong fastness and stress resistance. The application of temporary remedial measures can achieve great results.Repairing mechanical cracks After the oil-cutting of a hydrogen-chlorine gas cycle compressor in a factory caused a bush-burning accident, a main uranium bearing seat on the fuselage produced two axial cracks about 25mm deep.

The material is HT85-25 with poor weldability. If the cracks are repaired by surfacing welding, large deformation and residual stress are prone to occur, and the work load of removing excess weld meat is relatively large. Therefore, it was decided to use Belzona super metal repair agent. This is a two-component adhesive composed of polymer and metal powder with high silicon content. The repaired bearing seat was inspected intact after 14 months of operation.
