The control process of hot melt adhesive technology (1) surface treatment control: In order to make the bonding quality is reliable, surface treatment of the heart must be carefully controlled. Physical or chemical methods can be used according to need to deal with surface. To keep the surface clean and dry before bonding. (2) early cooperate to control: All glued parts assembly together in front of the coating, to check whether can close contact. When pre match is no problem, deal with every glued parts in advance with marking, so after the glue the parts would be easy to match the whole assembly. (3) the glue control: Most of the structure when use the bottom glue to glue, glue used air or method of airless spraying. Usually at the end of the thickness of the adhesive can affect the bonding strength, therefore should be control and inspection, typically by regular inspection glue, after drying primer thickness to complete measurement. (4) the assembly control: Glue parts used a tool or clamping device to make it up. At this time should be clean and applicability of inspection tools. At the same time also want to check whether the glued parts assembly according to the correct order and cooperation. (5) curing control: Any joint of hot melt adhesive curing is a function of time - temperature, pressure, curing duration timing by manual or automatic timing control device.
