Epoxy resin industry is global industrialization development starts prior industry.
As the rapid development of our country economy, demand of epoxy resin market jumps, in recent years, our country introduced abroad's advanced production technology and technology unit in succession, epoxy resin industry is able to grow quickly, already became the whole world to the biggest epoxy resin is produced and consume one of countries now.
According to the report, up to 2021, our country epoxy resin is produced can make an appointment with 2.49 million tons / year, rise compared to the same period 7.6% , crop makes an appointment with 1.94 million tons, grow 11.2% compared to the same period, promotion of rate of industry whole start working comes 77.9% , be in the top level that comes nearly 10 years. Visible, the applied demand in chemical industry shows epoxy resin to rise situation steadily.
Market demand is clear, so, what is epoxy resin after all, what use to have again? Today's content, let us be shared in detail.
Epoxy resin material is the tradition application domain of thinner of annulus oxygen active, and still be the main application domain of thinner of active of current annulus oxygen, its have peculiar good physics machinery and dielectric protecties, with all sorts of material stick receive performance, and the flexibility that its use technology. Accordingly it can make material of makings of coating, composite material, mould, adhesive, mould pressing and inject expect into profile, wide application receives in each domains of national economy.
1 coating utility
Epoxy resin holds larger proportion in the application in coating, it can make each have characteristic, use the breed of each different. Its general character:
(1) is able to bear or endure chemical sex is admirable, be able to bear or endure especially alkalescent;
(2) paint film adds exert oneself strong, be opposite especially metal;
(3) has better hear resistance and insulating property;
(Colour retention of 4) paint film is better.
But of coating of double phenolic A epoxy resin be able to bear or endure the difference that await a gender, loss of gloss of easy pulverization of paint film outdoors is owed again plump, should not be outdoors use with what coating reachs coating of tall adornment sex. Because coating of this epoxy resin basically uses as priming paint of anticorrosion lacquer, metal, insulating varnish, but the coating that epoxy resin makes annulus a group of things with common features can use heterocycle and fat at outdoors.
2 adhesive utility
Epoxy resin besides plastic to the blame polarity such as polyolefin caking property bad besides, be like aluminous, steel, iron, copper to all sorts of metal stuff; Metalloid material is like glass, lumber, concrete to wait; And hot solid sex is plastic wait to have like not phenolic aldehyde, amino, saturated polyester stick admirably receive performance, say because of what this has all-purpose glue. Annulus oxygen adhesive is the important breed of structural adhesive.
The main use of epoxy resin adhesive
Equipment of 3 electrons phone expects
As a result of the insulation property of epoxy resin intensity of tall, structure is mixed greatly sealed performance is good wait for a lot of distinct advantages, already pressed electric equipment, electric machinery and electron in on any account yuan the insulation of parts of an apparatus reachs a mount to get applied extensively, development is very rapid. Basically use at:
(Insulation of 1) electric equipment, electric machinery is enclosed pouring. The insulation of integral hermetically sealed that controls electrical appliance like the discretion such as transformer of coil of electro-magnet, contactor, transformer, dry type is enclosed make. Rapid development got in electric equipment industry. From often press vacuum is pouring, pouring already developed automatic pressure gel to shape.
Annulus oxygen adhesive builds the main use that go up in building
Annulus oxygen adhesive is in the main use on the car
(2) is used extensively at sealing insulation of the fill of the parts of an apparatus of electronic component and circuitry. Already made the important insulating material with electronic indispensable industry.
(Makings of moulding of oxygen of ring of 3) electron class is used at semiconductor yuan the model of parts of an apparatus is sealed. Development is splitting in recent years. Because its performance is superior, have the tendency that the metal that replaces a tradition, pottery and porcelain and glass enclose greatly.
(Makings of compression moulding of layer of 4) annulus oxygen applies in domain of electron, electric equipment very wide. Among them the development of copperplate of annulus oxygen Fu especially rapid, already made one of fundamental material of electronic industry.
In addition, adhesive of coating of annulus oxygen insulation, insulation and electric adhesive also have a large number of application.
4 projects are plastic with composite material
Annulus oxygen project is plastic and main the material of annulus oxygen moulding that includes to be used at high pressure to shape and annulus oxygen lamination are plastic, and annulus oxygen expanded plastics. Annulus oxygen project is plastic the annulus oxygen that also can be being regarded is a kind of broad sense composite material. Composite material basically has annulus oxygen annulus oxygen glass reinforced plastics (general-purpose composite material) with composite material of annulus oxygen construction, if pull,squeeze shaping annulus oxygen profile, twine goods of shaping hollow swing tower and high-powered composite material. A kind of composite material is the hi-tech domain such as chemical industry and aviation, spaceflight, war industry important construction material mixes annulus oxygen functional material.
5 earth build material
Basically use as mortar of oxygen of anticorrosive level ground, annulus and concrete products, advanced road surface and airport runway, fast adhesive of the material of form a vesicle that repairs foundation of foundation of material, consolidate, building and coating.
