molding sand binder - Introduction
The molding sand binder is a material used to prepare molds and sand cores. It is a binder that can bind sand grains and provide sufficient strength. The following is a description of some of the properties, uses, methods and safety information of the sand binder:
Nature:
1. Cohesiveness: The sand binder can bond the sand grains together to form a solid mold or sand core.
2. hardenability: The molding sand binder can harden under proper conditions to form a solid with certain strength and wear resistance.
3. storage stability: sand adhesive should have a long storage life, not easy to deteriorate or lose the bonding performance.
Use:
sand binder is widely used in the casting process of mold preparation and sand core preparation, commonly used in the manufacture of metal castings, ceramic castings, etc.
Preparation Method:
The preparation of the molding sand binder usually includes the following steps:
1. select the binder: select the appropriate binder according to the need, such as resin, starch, etc.
2. Add additives: add appropriate additives to the binder, such as curing agent, hardener, etc.
3. mixing evenly: the binder and additives are fully mixed evenly, so that the binder has appropriate viscosity and workability.
4. Hardening process: According to the nature and requirements of the molding sand binder, it is hardened under suitable conditions to form a solid structure.
Safety Information:
in the use of sand binder, should pay attention to the following safety matters:
1. avoid direct contact: sand adhesive may be irritating to the skin and eyes, use should wear appropriate protective gloves and glasses.
2. Good ventilation: When preparing and using the molding sand binder, ensure good ventilation to avoid inhaling harmful gases or dust.
3. Storage Note: Store the molding sand binder in a dry, cool place, and away from fire and flammable materials.
