Liimamääriä

Liimamääriä refers to the quantity of adhesive applied in a given area or application. This is a critical factor in the performance and reliability of any glued joint. The optimal liimamäärä depends on several variables, including the type of adhesive, the materials being bonded, the surface area, the expected stresses, and the environmental conditions.

Too little adhesive can result in insufficient contact between the surfaces, leading to a weak bond that is prone to failure. Inadequate coverage means that the load will be concentrated on a smaller area, increasing stress and potentially causing the bond to break prematurely.

Conversely, applying too much adhesive, or excess liimamäärä, can also be detrimental. This can lead to adhesive squeeze-out, which can create messy surfaces, potentially contaminate surrounding areas, and in some cases, weaken the bond itself by creating a thicker, less controlled adhesive layer. Excessive amounts can also increase costs due to wasted material. Furthermore, in some sensitive applications, uncured adhesive squeeze-out can interfere with the function of the assembled parts.

Accurate control and measurement of liimamäärä are therefore essential for achieving consistent and strong adhesive bonds. This is often achieved through specialized dispensing equipment that can precisely control the flow rate and volume of adhesive applied. Methods for determining appropriate liimamäärä include empirical testing, manufacturer recommendations, and engineering calculations based on bond strength requirements.
