The nature and use
of resin in the field of chemical production raw materials
1. Introduction

resin is an important kind of chemical production raw materials, widely used in plastics, coatings, adhesives, fibers and other fields. In this paper, the nature and use of resin will be discussed in detail.

2. the properties of the resin

1. Physical properties: The resin is usually a solid or semi-solid material with a high viscosity. They generally have good thermal stability and electrical insulation.
2. Chemical properties: The resin molecule contains a large number of functional groups, such as hydroxyl, carboxyl, amino, etc. These functional groups make the resin have good reactivity and can chemically react with a variety of compounds. The use of

1. plastic manufacturing: resin is the main raw material of plastic, by adding a variety of additives and fillers, can produce a variety of excellent performance of plastic products. For example, polyethylene resin is the main raw material for the manufacture of plastic bags, pipes and other products.
2. Coating manufacturing: resin as the main film-forming material of the coating, can provide good adhesion, corrosion resistance, weather resistance and other properties of the coating. For example, acrylic resins are important raw materials for the manufacture of automotive paints, architectural paints and other coatings.
3. Adhesive manufacturing: The resin can be used as the main component of the adhesive to provide the adhesive with good bonding strength and durability. For example, phenolic resin is the main raw material for the manufacture of woodworking glue, laminate and other adhesives.
4. Fiber manufacturing: Some resins can be used as raw materials for fibers. For example, polyester resin is the main raw material for manufacturing polyester fibers. The development prospect of

With the continuous development of science and technology, the application field of resin is also expanding. In the future, the resin will pay more attention to environmental protection, high efficiency, functional and other directions. For example, the research of some biodegradable resins is gradually being carried out to solve the problem of plastic pollution; some high-performance resins are also being developed to meet the application needs under extreme conditions such as high temperature and high pressure.

In short, resin as an important class of chemical production raw materials, in the future development will continue to play an important role.
