Adhesion technology is an important component of modern industrial production, and it has been widely used in automobile manufacturing, electronics industry, construction industry, etc.
Adhesives have been used for a long time by humans. Archaeological data indicate that nearly 70,000 years ago, prehistoric human beings used natural ingredients such as gum and resin to bond objects together. These early adhesives have been widely used for the production of wooden tools, paintings, etc.
In the modern world, the development of adhesive technology becomes more and more rapid. Adhesive technology is a new technology combining chemistry, mechanics, and engineering. It not only keeps traditional adhesives, but also develops new adhesives with high strength and good adhesion. Today, glue has become an important component of industrial production, and various glues can be used in more than 20 major industries, including automobiles, airplanes, ships, electronics, medicine, construction, and more.
The use of adhesive technology can not only reduce the production cost of products, but also expand the application of materials and improve the performance of products. The main application of adhesive technology in industry is mainly divided into three aspects: bonding, sealing and protection.
In terms of bonding, refers to the adhesive in the process of bonding two substrates together with the help of adhesive, forming a combined part with certain strength and performance. Commonly used adhesives are epoxy adhesives, polyurethane adhesives, polyvinyl acetate emulsions, emulsion pressure sensitive adhesives and structural adhesives.
In terms of sealing, it refers to the use of adhesives physical properties and drapeability to seal the joint of two objects, which can prevent external substances from entering and damaging the items. Commonly used sealing agents are silicone sealants, polysulfide sealants and polyurethane sealants.
In terms of protection, it refers to using adhesives to stick protective materials to the surface of the object in order to enhance the positioning accuracy in operation and assembly, so as to protect the accuracy and surface of the object. Commonly used protective materials are duck tape, Kapton tape and PET insulation tape.
The selection of adhesives to be used in industry is also very important, mainly including the selection of types and dosage of adhesives, the selection of adhesive viscosity, the selection of bonding technical parameters and the selection of application mode. Different adhesive raw materials must be selected according to the characteristics of different substrates, the types of materials and the requirements of usage.
In brief, adhesive technology has been widely used in various industries, and its use can not only improve product performance, but also solve many technical problems. Adhesives are becoming increasingly important in industrial production, and the development of adhesive technology continues to bring convenience to industry.
