The surface of the material to be bonded must be treated with decontamination, rust removal and degreasing before the adhesive is coated. Generally, rust removal is carried out by sandblasting, grinding wheel and sandpaper, and degreasing is carried out with solvents such as toluene, acetone and ethanol. After treatment, the surface should be dry and smooth.
2。 The second step is to configure the glue solution。 The preparation of adhesive depends on the requirements of the material to be adhered, and can be mixed with other adhesives according to different proportions。
3, finally, coating and curing are carried out. When the prepared glue solution is used for coating, the glue solution can be coated on the surface of the treated material with an oil painting pen, and the glue solution can be placed for 5 to 10 minutes after the first coating, and then placed for 10 to 20 minutes after the second coating. Then, the surfaces of the bonded materials are bonded together, and after reinforcement, the pressing time is ten hours, the box bonding piece can reach the maximum bonding strength after standing at room temperature for one day and night, and it takes three to five days to reach the maximum strength, and the curing time can be shortened by heating and curing.
