Question

Почему склеиваемые детали рекомендуют крепко прижимать друг к другу??Помогите срочно надо))

Answer 1

Потому, что взаимодействие молекул проявляется на расстояниях столь же малых, как и сами молекулы. 

Answer 2

Молокулы соединятся и вероятность отталкивания молекул будет нулевая.

Answer 3

Why are adhesive parts recommended to be firmly pressed together?

When using adhesive materials, it is recommended to firmly press the adhesive parts together for several reasons:

1. Enhanced Bonding: Firmly pressing the adhesive parts together ensures maximum contact between the adhesive and the surfaces being bonded. This helps to create a stronger and more reliable bond between the materials [[1]].

2. Uniform Distribution of Adhesive: Applying pressure helps to evenly distribute the adhesive material between the surfaces being bonded. This ensures that there are no gaps or air bubbles, which can weaken the bond [[2]].

3. Improved Adhesive Wetting: Pressing the adhesive parts together helps to improve the wetting of the adhesive on the surfaces. Wetting refers to the ability of the adhesive to spread and intimately contact the surfaces being bonded. Proper wetting enhances the adhesive's ability to form strong molecular bonds with the surfaces [[3]].

4. Exclusion of Air: Applying pressure helps to remove any trapped air between the adhesive and the surfaces being bonded. Air bubbles can create weak spots in the bond and reduce its overall strength. By pressing the parts together, air is expelled, resulting in a more solid bond [[4]].

5. Accelerated Cure: Some adhesive materials require a curing process to reach their full strength. Applying pressure can help accelerate the curing process by promoting better contact between the adhesive and the surfaces. This can lead to faster bonding times and increased bond strength [[5]].

It is important to note that the specific instructions for applying pressure may vary depending on the type of adhesive being used. Always refer to the manufacturer's guidelines for the recommended pressure and curing times for the adhesive you are using.
