The nature and use
of adhesive in the field of chemical production raw materials
adhesive is an important chemical product, widely used in various fields, especially in the field of chemical production raw materials, adhesive plays an important role. This article will detail the nature and use of adhesives.

1. the nature of the adhesive

adhesive is a substance capable of adhering two objects and holding them together. It is usually composed of polymer, resin, rubber and other polymer compounds. The properties of adhesives mainly include the following aspects:

1. Adhesion: The adhesion of an adhesive refers to its ability to adhere two objects and keep them together. The magnitude of the adhesion depends on factors such as the composition of the adhesive, the surface properties of the adherend and the adhesion conditions.

2. viscosity: viscosity refers to the fluidity of the adhesive. The higher the viscosity, the worse the fluidity of the adhesive, and vice versa, the better the fluidity.

3. Curing method: There are many ways to cure the adhesive, including water-based, solvent-based, hot-melt, light-curing, etc. Different curing methods will affect the nature and use of the adhesive.

4. Chemical resistance: The chemical resistance of the adhesive refers to its ability to resist chemical corrosion. Different adhesives have different resistance to different chemicals. The use of

adhesive in the field of chemical production raw materials have a wide range of uses, mainly including the following aspects:

1. composite material manufacturing: adhesive can be used in the manufacture of composite materials, such as glass fiber reinforced plastic, carbon fiber composite materials, etc. It can adhere different materials together and improve the strength and toughness of the material.

2. packaging industry: adhesives can be used in the packaging industry, such as cartons, cartons, bottles and other packaging bonding. It can improve the strength and sealing of the packaging and protect the product.

3. construction industry: adhesives can be used in the construction industry, such as tiles, floors, walls and other materials paste. It can improve the durability and aesthetics of the building.

4. Automobile manufacturing: Adhesives can be used in automobile manufacturing, such as the assembly of body, interior and other components. It can improve the sealing and comfort of the car.

In short, adhesives have a wide range of uses in the field of chemical production raw materials, and play an important role in improving product quality and production efficiency. The development trend of

With the continuous development of science and technology, adhesives are constantly improving and improving. In the future, the development trend of adhesives is mainly reflected in the following aspects:

1. Environmental protection: With the improvement of people's awareness of environmental protection, the development of adhesives in the future will pay more attention to environmental protection and reduce environmental pollution.

2. High performance: With the improvement of adhesive performance requirements in various fields, the future development of adhesives will pay more attention to high performance, improve adhesion and chemical resistance and other aspects of performance.

3. Multifunctionality: The development of adhesives in the future will pay more attention to multifunctionality, meet the different needs of adhesives in different fields, and increase the added value of products.

In short, adhesives, as an important part of the field of chemical production raw materials, will continue to play an important role in the future, providing support and protection for the development of various fields.
