Furan resins refer to a kind of
thermosetting resin that contain furan ring in the molecular structure.
Its main products are furfuryl alcohol resin, modified furfuryl alcohol
resin, furfural-acetone resin, furfural-phenol resin and so on.
The
resin has small shrinkage when curing, and the curing are
insolubility-melt black brittle solid, while its advantages are that the
heat resistance and chemical resistance are superior to the phenolic
resin and epoxy resin.
The
main production raw material of furfuryl alcohol resins are furfuryl
alcohol, maldehyde and urea. Catalyst are sodium hydroxide and vinegar.
Curing agent has P-toluene sulfonic acid, xylene sulfonic acid, benzene
sulfonic acid and so on.
Furan resins are mainly used as chemical-resistant and high turbidity materials.
1
Chemical-resistant materials of furan resin available to prepare the
corrosion resistant PuTTY used as lining or other corrosion-resistant
material of chemical equipment.
2 Heat resistance of reinforced
composites for furan glass fiber is higher than general phenol aldehyde
glass fibre reinforced composites. Usually it can be the long-term use
at about 150 ℃.
3 Blending modification with epoxy or phenolic
resin to make the furan resin mixed rest use with epoxy or phenolic
resin. This improves furan glass fiber-reinforced composite material
mechanical properties and process performance of preparation. This type
of composite material has been widely used for the preparation of
chemical reactor mixing devices, storage tanks, pipelines and other
equipments.
4 High valuable in industry. Furan resins are widely
used in the metallurgy and casting industries. It also applied to
production of auto parts, plumbing, tire mold.
The application of furan
resin process modeling can access to good economic results.
Because
of furan resin has excellent corrosion resistance, heat resistance,
advantages of its sources of raw materials and the production process is
simple, it has long drawn people's attention. If you want to know more
