The working bonding strength of TPU hot melt adhesive film
The working bonding strength of TPU hot melt adhesive film refers to its adhesion force with the adhered object under specific temperature and pressure. Due to its excellent bonding performance and durability, TPU hot melt adhesive film is widely used for bonding and fixing various materials, such as fabrics, leather, plastics, metals, etc.
There are various methods for testing the bonding strength of work, and one commonly used method is the 90 degree peel test. This method involves pasting TPU hot melt adhesive film onto the adhesive, then placing it on a specific peeling machine to peel at a certain speed and angle, and recording the required force value. This force value is the working bonding strength and is one of the important indicators for evaluating the performance of TPU hot melt adhesive film.
There are many factors that affect the bonding strength of TPU hot melt adhesive film, among which the most important are the material and surface treatment of the adhered material. Different materials have different adhesive forces on the adhesive film, so in practical applications, it is necessary to choose the appropriate adhesive film based on the material of the adhesive. Surface treatment is also a key factor affecting adhesion, and the surface of the adhered material must be clean, dry, and free of impurities such as oil stains to ensure the best adhesion effect.
In addition to the material and surface treatment of the adhered material, the formula and production process of TPU hot melt adhesive film are also factors that affect its working bonding strength. Different formulas and processes can lead to different physical properties such as viscosity, melting point, and crystallinity of the adhesive film, thereby affecting its bonding performance. Therefore, in practical applications, it is necessary to choose the appropriate adhesive film formula and production process according to the specific situation.
In practical applications, in order to improve the working bonding strength of TPU hot melt adhesive film, the following methods can be used:
1. Surface treatment of the adhered material, such as polishing, sandblasting, chemical treatment, etc., to improve surface energy and increase bonding strength.
2. Choose the appropriate TPU hot melt adhesive film formula and production process to achieve the best physical and bonding properties.
3. Apply a certain amount of pressure and temperature during the pasting process to ensure close contact between the adhesive film and the object being adhered, increasing the bonding area and strength.
4. For bonding parts that need to withstand gravity for a long time, regular inspections and maintenance should be carried out, and damaged parts should be repaired in a timely manner to ensure bonding strength and safety.
In summary, the working bonding strength of TPU hot melt adhesive film is one of the important indicators for evaluating its performance. In practical applications, it is necessary to choose the appropriate adhesive film formula, production process, and surface treatment method according to the specific situation to ensure the best bonding effect. At the same time, for bonding parts that need to withstand gravity for a long time, regular inspections and maintenance should be carried out, and damaged parts should be repaired in a timely manner to ensure bonding strength and safety.
