Coated sand refers to molding sand or core sand covered with a layer of solid resin film, and the use of flake graphite in coated sand is used to prevent peeling during the use of coated sand. Below, we will provide a detailed explanation of the functions of flake graphite in coated sand.

The flake graphite used in coated sand is used as a lubricant in coated sand. The flake graphite used in coated sand can play a role in lubrication and high temperature resistance. The requirements for flake graphite used in coated sand are to have good lubrication performance and high melting point as a lubricant. And the flake graphite used for coated sand is made of natural flake graphite with good lubrication, which has been purified and processed to increase its carbon content. The melting point of flake graphite itself is high, and after production process processing, the high-temperature resistance of flake graphite used for coated sand will be higher, and the lubrication effect will be better.

The function of flake graphite used in coated sand is to prevent agglomeration and improve the flowability and demolding ability of the coated sand. Flake graphite for coated sand can not only improve the lubricity and wear resistance of coated sand, but also improve its high temperature resistance. Coated sand processed by coating process through natural quartz sand, thermoplastic phenolic resin, flake graphite for coated sand and other materials can be used to produce various complex castings such as automobile cylinder block, cylinder head, intake manifold, various pipe fittings, pump body, etc.

Coated sand is processed with natural quartz sand as raw sand, thermoplastic phenolic resin, urotropine and coated sand with flake graphite, reinforcing agent and other raw materials. The role of flake graphite for coated sand is to prevent coated sand from shelling during use.
