The Leader of Wisdom-Cheng Jinsong, Chairman of Quzhou Xinsong Resin Co., Ltd.

2024-06-07

At the beginning of Cheng Jinsong's establishment of the factory, the factory was mainly engaged in the deep processing of rosin. However, due to certain problems and factors in the enterprise development system in the early stage of reform and opening up, as well as many restrictive factors such as resources, environment, transportation and talents, the factory has become a riddled, distracted, seriously losing money and on the verge of bankruptcy. In recent years, through market research, Cheng Jinsong realized that the products of the enterprise have development potential, and can also fill the blank of resin production of forest chemical products in our province, so he boldly proposed to reform the enterprise.

Pretreatment of resin before use

Before using the resin, it is first necessary to completely remove the impurities on the surface. Cleaning can be used in a variety of ways, such as mechanical cleaning, chemical cleaning, gas cleaning, etc. Mechanical cleaning is generally polished or polished, and chemical cleaning can use solvents or alkaline cleaning agents to clean the organic and inorganic salts on the surface of the resin. Gas cleaning uses high-pressure gas to blow away impurities on the surface of the resin. When choosing the cleaning method, you need to choose according to the different materials and use environment of the resin.

Discussion on Resin Material

2024-06-14

Resin material is a kind of high chemical molecular material extracted from plants for making various substances. It has the characteristics of structural stability, high temperature resistance, and the form is diverse. At room temperature, the resin material is solid, medium solid, false solid, but sometimes it is also a liquid organic substance. The resin material has a softening or melting temperature range, has a tendency to flow under the action of external force, and is often shell-shaped when broken. Broadly refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents.

Basic characteristics of different types of resins

Coatings are generally composed of film-forming materials, pigments, additives, solvents, diluents, etc. After the construction of the coating, with the evaporation of the solvent and the diluent, the film-forming material is dried and formed into a film. The film-forming material can be formed separately, or it can be bonded to the pigment and other substances to form a film together, so it is also called a binder, which is the basis of the coating.

Various resin models and uses

2024-06-14

The types and uses of resins are very wide, mainly can be divided into addition polymers and condensation polymers, natural resins and synthetic resins, carbon chain polymers, hetero-chain polymers and elemental organic polymers, as well as thermosetting resins and thermoplastic resins classified by nature.

Resin is not a plastic.

2024-06-14

Resin is a raw material that can be used to make plastic, so resin is also considered a plastic. Resins and plastics are materials that can be shaped. However, different people may have different opinions about the difference between resin and plastic. In a strict sense, resin is a natural or synthetic amorphous solid substance, and plastic is a product made of resin plus some other additives (such as fillers, plasticizers and pigments). Therefore, it can be said that resin is a raw material for manufacturing plastics. In some everyday language, sometimes people informally regard resin as a kind of plastic, called "resin plastic".
