Epoxy Resin in the Workplace and in Life
Epoxy resin's excellent electrical insulation and adhesive properties of varied materials, also because the flexibility to other thermosetting plastics, aren't available. So it made paint, composite materials, casting materials, adhesives, molding materials and injection molding materials, which are widely applied altogether areas of the economy .
First, paint
Epoxy resin accounts for an outsized proportion in coatings,
which are in common:
1, excellent chemical resistance, particularly alkali.
2, the film adhesion, especially for metal.
3, good heat resistance and electrical insulation.
4, good paint and color retention.
However, bisphenol A epoxy coating and poor weather are easy
to powder coating and not suitable for outdoor use. Therefore it's mainly used
for anti-corrosion epoxy coating paint, metal primer and polish , but the
heterocyclic and alicyclic epoxy coating are often made outdoors.
Second, adhesive
A variety of metal materials like aluminum, steel, iron,
copper;non-metallic materials like glass, wood, concrete, etc; thermosetting
plastics like phenolic, amino, unsaturated polyester all have excellent
adhesive properties. Structural adhesive epoxy adhesive is a crucial species.
Third, electrical and electronic materials
As epoxy has many unique advantages like high insulation
performance, high structural strength and sealing performance. it's widely
applied and developed rapidly in high and low voltage electrical appliances,
electrical and electronic components and packaging of insulation. Mainly used
for:
1, Electrical appliances, electrical insulation package,
casting parts. like solenoid, contactor coils, transformers, dry type
transformer high-voltage electrical insulation package, the entire sealed
parts. within the electrical industry it's developed rapidly. it's been
developed from the pressure casting and vacuum casting to the automated
pressure gel.
2, it's widely utilized in electronic components AND circuit
encapsulation device, which has become a crucial and indispensable insulant in
industry .
3, Electronic grade epoxy molding compounds are used for
semiconductors in recent years. due to its superior performance, much trends to
exchange the normal metal, ceramic and glass packaging.
4, Epoxy laminated plastic features a wide selection within
the electronic and electrical field. Particularly epoxy laminate with rapid
development has become one among the essential materials of electronic
industry.
In addition, the epoxy insulating coatings, adhesives and
electrical insulation adhesive even have an outsized number of applications.
Epoxy molding engineering plastics mainly include epoxy
molding compounds and epoxy laminated plastic and epoxy foam plastics for
high-pressure molding. Epoxy composite materials mainly include epoxy
FRP(universal composite materials)and epoxy composite, like epoxy pultrusion
profiles, filament winding of the hollow rotary system products and
high-performance composite materials. Epoxy material is a crucial structural
and functional materials in chemical, aviation, aerospace, military and other
high-tech areas.
Fifth, engineering materials
They are primarily utilized in preservative floors, epoxy
mortar and concrete products, tops of the roads and airport runways, rapid
repairing materials, reinforcement of foundation grouting materials,
construction adhesives and coatings.
In the chemical water treatment systems, for various
reasons, anion-cation exchange resin has been polluted, especially the
pollution of calcium, iron and organic, leading to the drop of polluted resin.
because the structure of the resin isn't destroyed, it are often treated
appropriately to revive the exchange performance. At an equivalent time analyse
the method of the utilization of resin contamination and take reasonable
measures to stop.
