What are the different types of industrial adhesive?
The adhesive is a substance that holds or ties two different surfaces together. There are different types of industrial adhesive and are usually classified according to their adhesive properties, composition or mechanism of treatment. The treatment mechanism refers to the adhesive hardening process using chemicals, heat or ultraviolet light. The ways in which the resin is used as an industrial adhesive depends on its physical and chemical properties.
resins are polymers of synthetic origin. The polymer is a large molecule consisting of a combination of smaller molecules. The resin can be classified into thermoplastic and thermosets. Thermoplastic resins can be re-moconuts at high temperatures and become rigid after cooling. On the other hand, thermoset resin cannot be cured after the process of curing. As industrial adhesives, thermoplastic adhesives are used as industrial adhesives, such as polyvinylace (PVA), cyakrylate or superglue, silicone resins and polyamides .. these resinsE are resistant to oil, but show poor resistance to heat, water and sneaking at high loads. This type of industrial adhesive can bind most materials such as wood, ceramics, metal and laminates. They are widely used in applications such as bolt lock sets.
Some of the most common thermoset types of industrial adhesive are epoxy resins, polyurethrans and phenolic resins. As with other thermoset resins, epoxy resins can be cured by catalysts, classes, heat or ultraviolet light depending on a specific industrial requirement. High -performance structural adhesive has a very high chemical and thermal resistance, especially those cured at extremely high temperatures.
epoxy adhesives are widely used in the plane and the automotive industry. Polyurethran resins will quickly cure and can even combine the surfaces of BeTon. Phenolic resins are mainly used in the production of plywood.
Based on the curing mechanism, adhesives can be classified into physical hardening, chemical hardening and pressure of sensitive resins. Adhesives with warm shattering, plastic, water adhesives and organic solvent adhesives are different types of physical hardening of industrial adhesive. In particular, this category includes adhesives that can be melted, such as thermoplasty.
hot -cutting adhesives are mainly used in the furniture, packaging and electronics industry. These solid adhesives usually soften when heated; The substrates soak with them anyway. Plastisol is an industrial adhesive that is widely used in the vehicle. Water -based adhesives are easy to clean adhesives that contain polymers dissolved or dispersed in water. Wet adhesives and contact adhesives are two classes of polymer adhesive based on water.
Chemical hardening of industrial adhesive requires chemical reaction for bonding two surfacesnurses. These adhesives are classified into one -component and two -component adhesives. Single compound resins are further classified into thermal cure, moisture treatment and treatment of radiation and anaerobic adhesives and cyanoacrylates. These adhesives are mainly used in the automotive industry, optics, microelectronics and the medical industry. Urethane adhesive, epoxides and silicon adhesive are different types of two -component adhesives.
pressure resin sensitive resin facilitates the connection between surfaces by means of sufficient pressure. These resins are mainly used in filters and membrane switches. In some cases, pressure sensitive resins are designed to be easy to remove.
