Belt cold bonding glue is a film used for belt connection, which adopts cold bonding glue technology and does not require any heat source. It is suitable for many types of belts, such as conveyor belts, pipeline conveyor belts, wear-resistant conveyor belts, etc. When using German belt cold adhesive, you need to pay attention to the following points.
The temperature and humidity of the use environment have an important influence on the curing effect of cold adhesive. Too low temperature may cause the cold bonding glue to cure slowly, while too high humidity may affect the bonding strength of the glue. Therefore, the construction environment should be kept dry and well ventilated, and avoid using it in a humid or high temperature environment.
Before bonding, the surface of the belt to be bonded must be clean, dry and rough. Use a special cleaner to thoroughly remove impurities such as oil, dust, etc. to ensure that the bonding surface is clean and free of impurities. If necessary, a grinding tool can be used to remove the aging layer and ensure that the bonding surface is rough to increase the adhesion of the glue.
Two-component cold bonding glue needs to be accurately prepared according to the proportions in the instructions. Usually, measuring tools such as measuring cups are required to ensure the accuracy of the proportions. After preparation, stir thoroughly to avoid uneven local curing. The prepared glue must be used up within the specified activation period to avoid long-term storage leading to curing.
Use a brush to evenly apply glue and control the coating thickness to avoid being too thick or too thin. It is generally recommended to apply two layers, with each layer thickness controlled between 0.1-0.2mm and a total thickness of no more than 0.5mm. After applying the glue, let it dry for a while, and then bond it after the glue surface is no longer sticky. When bonding, start from one end and slowly bond to the other end, and use a rolling tool to expel air while bonding to ensure that the bonding surfaces are in close contact.
After bonding, use rollers and other tools to compact to enhance the bonding effect. Then, let the glue cure naturally at room temperature according to the curing time required by the instructions until it reaches the ideal bonding strength. During the curing process, avoid vibration and external interference to ensure that the glue is completely cured.
