AVENTK UV Adhesives
In daily life and electronic manufacturing, industrial production, adhesives are no stranger to everyone. With the development of technology, the types and applications of adhesives are getting richer and richer. AVENTK UV adhesive is the most widely used adhesive in the world,
As an adhesive manufacturer, AVENTK produces a variety of adhesive types including UV adhesive, epoxy adhesive, heat curing adhesive, UV moisture double curing adhesive, UV heat curing adhesive, UV delayed curing adhesive and other types of adhesives, the application field covers optical communication, medical, electronics manufacturing, consumer electronics production, new energy, security, PCBA, crafts production and other industries.
AVENTK has shared with you about how to choose adhesives in previous articles. Today, AVENTK has organized the four technical principles of adhesives, to bring you to understand adhesives from the technical field, to help you choose a more suitable adhesive products. If you have questions about adhesives, please feel free to communicate with AVENTK!
Adhesive four technical principles
First, mechanical interlocking
As the name suggests, the adhesive glue coated on the surface of the object to be adhered to, and into the surface of the object to be adhered to the gap, to be cured, the gap in the glue and the object to be adhered to the glue will be hooked together with each other to form the bonding effect.
Second, the principle of adsorption
Adhesive surface due to the role of van der Waals forces can adsorb liquid and gas, this role is physical adsorption, when the molecular spacing < 0.5nm, the two molecules will produce adsorption, and make the molecular spacing to further shorten the distance to be able to be in a stable state, so as to complete the role of the adhesive bond.
Third, the principle of diffusion
Chain molecules composed of adhesive, brushed to the surface of the material to be glued, under the action of the glue surface swelling or dissolution. Due to the adhesive molecular chain or chain segment of the Brownian motion, so that the molecular chain or chain segment from one phase into another phase, the two intertwined with each other, so that the interface between them disappeared, into a transition zone (layer), in the transition zone to form a mutually penetrating polymer network structure, thus obtaining a very high adhesive bonding strength.
Fourth, chemical bond crosslinking
There are various active groups or metal elements on the surface of the adherend, when the glue is coated on the surface of the adherend, the crosslinking agent in the glue will react with it, so that the colloid and the adherend will form a whole, to achieve the full effect of the adhesive bonding.
