Glue spreader materials of different materials have different properties.

Glue spreader materials of different materials have different properties.

(1)Metal:After the surface treatment of the oxide film on the metal surface, it is easy to Glue spreader; because the two-phase linear expansion coefficient of the Glue spreader adhesive metal is too different, the Glue spreader layer is prone to internal stress; in addition, the metal Glue spreader part Electrochemical corrosion is easily caused by water action.

(2)Rubber Glue spreader:The greater the polarity of the rubber Glue spreader, the better the Glue spreader effect.Glue spreader Glue spreader has a high polarity and a strong Glue spreader; the natural rubber Glue spreader, the silicone rubber Glue spreader and the Glue spreader have low polarity and weak adhesion.In addition, the surface of the rubber Glue spreader often has a release agent or a detachment agent released by the Glue spreader, which hinders the Glue spreader effect.

(3)Wood:It is a porous material that is easy to absorb moisture, causing dimensional changes, which may result in stress concentration.In addition, the polished material performs better than the rough surface wood Glue spreader.

(4)Plastic:The plastic Glue spreader Glue spreader with good polarity has good performance.

(5)Glass:The surface of the glass is composed of a plurality of uniform uneven portions from a microscopic angle.Use a wet Glue spreader adhesive to prevent possible air bubbles at the bumps.In addition, the glass is based on si-o-, and the surface layer of the Glue spreader is easy to adsorb water.Due to the strong polarity of the glass, the polar Glue spreader adhesive is easily hydrogen bonded to the surface to form a strong bond.The glass is brittle and transparent, so consider these when choosing a Glue spreader adhesive.
