1. Choose the appropriate hot melt adhesive: Select the appropriate type of hot melt adhesive based on the properties of the adhesive material, application scenarios, and adhesive requirements.
2. Control heating temperature: Excessive heating temperature may lead to a decrease in the performance of hot melt adhesive, and even burning; If the heating temperature is too low, it may cause the hot melt adhesive to not fully melt, affecting the bonding effect. Therefore, it is necessary to control the heating temperature reasonably according to the type and thickness of the hot melt adhesive.
3. Master the coating amount: Excessive hot melt adhesive may cause problems such as overflow and flow in the adhesive area, affecting the appearance and firmness; Insufficient hot melt adhesive may result in weak adhesion. Therefore, it is necessary to reasonably control the coating amount based on the adhesive area and requirements.
4. Pay attention to the operating environment: Avoid using hot melt adhesive in damp and dusty environments to avoid affecting its adhesive effect. At the same time, keep the operating area clean and avoid debris interfering with the bonding process.
