The compounding process of color steel composite plates is the production process of uniform glue for products. it is a special process of producing color steel composite plates and can also be called a special production process. Color steel composite board special glue is usually used, which is divided into group a glue ( black glue ) and group b glue ( white glue ). Single component adhesive ( commonly known as manual adhesive ) is used when the adhesive needs to be repaired and adhered. it can be used directly without distinction between a and b. Df - 202 glue is divided into winter glue and summer glue according to the limit of temperature difference. Color steel composite board glue should pay attention to whether the component a and component b have expired and deteriorated before bonding. In particular, component b is deteriorated due to easy polycondensation reaction. it should be stored under low temperature and sealed conditions. all steps should strictly follow the operating rules, otherwise it will affect the quality of bonding.
1. surface treatment: the surface of the material to be bonded must be decontaminated, derusted and degreased before the adhesive is coated. generally, sandblasting, grinding wheel, sandpaper and other methods are used to remove rust, and toluene, acetone, ethanol and other solvents are used to degrease and degrease. After treatment, the surface should be dry and smooth.
2。 preparation of glue solution: the preparation of adhesive depends on the requirements of the material to be adhered。 the components a and b have different proportions, and the adhesive can also be mixed with other adhesives。
3。 coating and curing: when using the prepared glue solution for coating, the glue solution can be coated on the surface of the treated material with an oil painting pen。 after coating for the first time, the glue solution can be placed for 5 - 10 min, and then for the second time, the glue solution can be placed for 10 - 20 min。 Then, the surface of the material to be bonded is bonded together, and the pressure of 0。03 - 0。05 MPa of the nail is used to cure the material。 the pressure time is several minutes to 10 hours, and the box adhesive can reach larger adhesive strength after being placed at room temperature for one day and night, and the highest strength needs 3 - 5 days。
