What are the furan resins? What are the main uses of furan resins?
furan resin is a resin made from acetaldehyde as the main raw material, because of the good corrosion resistance of this resin, simple manufacturing methods, has been widely used. Furan resin is resistant to non-oxidizing acids, alkali and organic solvents, which is of great significance to solve the problem of acid-base alternating medium corrosion equipment in production. Furan resins are superior in many properties than phenolic, epoxy and polyester resins, which can be used at temperatures of 180 degrees Celsius or
in
.
sterol resin is hydrogenated with acetaldehyde under pressure of 8-kg/cm2, and the sterol resin is polymerized under the action of acid catalyst. Sterol resin is the simplest to make, under normal pressure acetaldehyde and acetone for a shrinking reaction can obtain sterol resin.
furan resin can be used as an adhesive, impregnation agent, and epoxy resin modification can also be used as a coating, can also be used to make thermooensols and fiberglass products.
