Sclerotic resin sand - Names and Identifiers
Sclerotic resin sand - Introduction
Hardened resin sand is a kind of resin sand molding material widely used in foundry industry. It is composed of base resin, curing agent, filler and auxiliary agent. Hardened resin sand has the following properties:
1. High strength: The hardened resin sand has high strength and can withstand high pressure and impact.
2. High viscosity: resin sand has good adhesion, can bond sand and mold, the formation of solid sand.
3. High temperature resistance: hardened resin sand has high heat resistance and can withstand the casting process in high temperature environment.
4. Good fluidity: Resin sand has excellent fluidity and can fill all corners of the mold during the casting process to obtain accurate casting shapes.
The main use of hardened resin sand is for the production of sand molds in metal casting processes. By pouring hardened resin sand into a mold and then fully hardening, a desired casting shape can be obtained. This method is widely used in automobile manufacturing, machinery manufacturing, aerospace and other industries.
The method of making hardened resin sand is mainly divided into two steps: first, the basic material of resin sand is prepared, and the resin, curing agent, filler and auxiliary agent are mixed evenly according to a certain ratio; then the mixture is put into the mold opening machine or mixing equipment for stirring and mixing, so that the resin sand can obtain proper fluidity and hardening speed.
When using hardened resin sand, you need to pay attention to the following safety information:
1. The composition of resin sand may contain chemicals that are harmful to the human body, so personal protective equipment such as gloves, goggles and protective masks should be worn during operation.
2. In the process of preparing resin sand, it is necessary to follow the guidance provided by the manufacturer and prepare in strict accordance with the ratio to avoid unnecessary accidents.
3. When using hardened resin sand, it should be operated in strict accordance with the operating procedures to avoid direct contact with the skin or inhalation of sand and dust.
4. Waste hardened resin sand should be properly handled to avoid environmental pollution.
