Adhesive used in anti-static shoes
The anti-static shoes worn by the microelectronics factory shall be tested according to the national standard GB4385-1955 for the hardness/resistance of the sole of the antistatic shoes. The leather shall be analyzed for its thickness/tension. At the same time, in the process of the combination of the upper and the sole, attention should be paid to the degree of adhesion. If the opening phenomenon occurs, it will affect the environment of the electrostatic working area. In general, anti-static shoe factories often use the combination of pvc leather surface and pu bottom. When treating the upper surface and the pu bottom under this condition, a special treatment agent is usually used to make it strongly bond in the production process.
Currently, polyurethane adhesives are commonly used on anti-static shoes? This depends mainly on its characteristics. Polyurethane adhesives for antistatic shoes, like other polyurethane adhesives, have excellent low temperature properties, low curing temperatures, excellent flexibility, impact resistance, wettability and adhesion to many materials. Therefore, it is often used in applications requiring room temperature, rapid curing, and softness, and is particularly suitable for bonding dissimilar materials having different expansion coefficients.
In general, the performance requirements of shoe-making adhesives vary depending on the shoe material, shoe type and bonding process, but overall, the shoe adhesive should have the following properties:
1. It has moderate heat resistance, sufficient water resistance and bonding durability.
2. It has sufficient bonding strength to different materials and different crystalline materials, and the peeling strength is high;
3, the bonding initial viscosity is high, to meet the requirements of the shoe production line; especially the peel strength is high;
4. The sizing process is simple, easy to operate, and the use period is adjustable to meet the needs of the shoe production line;
A good adhesive acts on a good anti-static shoe, so that the quality of the anti-static shoes is guaranteed in detail. Ant anti-static mall provides.
