Epoxy resin pipe is a commonly used
electronic and electrical insulating material. It is resistant to high voltage,
corrosion, high temperature, high strength, and good electrothermal
performance. It can work for a long time under high voltage without fatigue. It
can be used normally in hot and humid environments. The use of excellent
anti-rust raw materials can ensure its anti-rust performance. It has good
mechanical strength, tough paint film, abrasion resistance and impact
resistance. The solid content is high and the coating film is thicker. Cured at
room temperature to form a film. No need for large-scale baking equipment.
The surface coating of the epoxy resin pipe
is a two-component, high-solid coating with epoxy resin as the main agent. It
is widely used in drinking water tanks, water pipes, water tanks and other
places. When spraying, the epoxy resin powder has not been completely fused to
the inner and outer walls of the substrate. After 30 minutes of preheating and
curing, the curing agent in the epoxy resin is completely cured, making the
coating on the inner and outer walls stronger and thermosetting. The powder
characteristics are fully revealed. Good corrosion resistance. Since the main
raw materials of FRP are composed of polymer unsaturated polyester resin and
glass fiber, it can effectively resist the corrosion of acid, alkali, salt and
other media, as well as untreated domestic sewage, corrosive soil, chemical
wastewater and many chemical liquids. The erosion, in general, can maintain
safe operation for a long time.
Epoxy resin pipe has been widely sought
after in the society after long-term development!
1, strong adhesion
The existence of polar hydroxyl and ether
bond inherent in the molecular chain of epoxy resin makes it have high adhesion
to various substances. The shrinkage of epoxy resin is low when cured, and the
internal stress generated is small, which also helps to improve the adhesion
strength.
2, strong contractility
The reaction between the epoxy resin and
the curing agent used is carried out by direct addition reaction or
ring-opening polymerization reaction of epoxy groups in the resin molecule, and
no water or other volatile by-products are released. Compared with unsaturated
polyester resins and phenolic resins, they show very low shrinkage (less than
2%) during curing.
3, electrical performance
The cured epoxy resin system is an
excellent insulating material with high dielectric properties, surface leakage
resistance, and arc resistance.
4, mechanical properties
The cured epoxy resin system has excellent
mechanical properties.
5, chemical stability
Generally, the cured epoxy resin system has
excellent alkali resistance, acid resistance and solvent resistance. Like other
properties of cured epoxy systems, chemical stability also depends on the resin
and curing agent selected. Appropriate selection of epoxy resin and curing
agent can make it have special chemical stability.
6, dimensional stability
The combination of many of the above
properties gives the epoxy resin system outstanding dimensional stability and
durability.
7, mold resistant
The cured epoxy resin system is resistant
to most molds and can be used under harsh tropical conditions.
