Is it important to introduce the compactness of the wall lamp?

1. The necessity of compaction

u003cbru003e  Adhesives produce adhesion while curing, so during the curing process of adhesives, to ensure the adhesion between the bonding surfaces is an important condition to ensure the adhesion: This requires the wall lamp before the adhesive starts to cure A pressing force must be applied to the bonding surface, at least contact pressure must be applied. If during the curing process, the bonding surfaces cannot maintain close contact, voids must be created in the bonding layer, which will affect the bonding quality. Appropriate application of pressing force can improve the wettability and permeability of the adhesive to irregularities on the surface, and help to form a complete thin and uniform adhesive layer.

u003cbru003e  2. The size of the pressing force

u003cbru003e  The size of the medical tightness is related to factors such as the type of adhesive and the type of material to be adhered, and it is generally within a wide range of 0.2 to 1.5 MPa. The pressing time depends on the type of adhesive and curing temperature. The application of pressing force generally starts after bonding or aging, and the wall lamp does not release the pressure until the adhesive is completely cured or basically cured.

u003cbru003e  3. Pressing operation requirements

u003cbru003e  The general requirements for compaction operation are: appropriate compaction force, uniform pressure distribution, sufficient compaction time, and no deformation of the adherend under pressure (except in special circumstances).

u003cbru003e  There are many ways to pressurize. The wall lamp should be selected according to the type, shape and characteristics of the adherend. Commonly used compression methods include lever weight compression, spring clamp pressure ticket, multiple heavy objects, sand bag area tight, air bag cushion, spring pad, autoclave, nail area tight, spiral clamp compression, Laminated area tightly equal method
