Description
Technical field
The present invention relates to a kind of plastics, particularly relate to a kind of bellows.
Background technique
At first, people are stitched into the structure of tubulose with animal skin, to adapt to the needs producing struggle.Have passed through quite long period, to 17th century last years of a century, ten thousand Dare Gai Jin brothers of Holland have made the canvas hose of longitudinal stitching, are widely adopted in fire-fighting business at that time.Afterwards, along with rubber appearance in the international market and the development of sulfuration process thereof, sebific duct and the sebific duct with the fabric such as wire or rope made of hemp armouring have come out.But, in engineering some steam, hot blast class high temperature media ' liquid hydrogen, the cryogenic media of liquid oxygen, liquid helium class, gasoline, kerosene, corrosive media such as acid, alkali, if carry with sebific duct, of course not.Particularly under the high temperature conditions, its safety reliability is just more difficult ensure that.
Therefore, people gradually visual cognitive ability to metal tube aspect, change the geometrical shape of metal tube, make its inner and outer surface produce corresponding ripple.Like this, it had both had the same flexibility of same sebific duct, meanwhile, had again high temperature resistant, low temperature resistant, ageing-resistant, decay resistance.So, create as the metal bellows of metallic hose body like this.
From nineteen fifties, double-deck, three layers, the bellows of multilayer, particularly very thin wall stainless steel material bellows develops very fast.In order to meet usage requirement, people adopt welding, electroforming, machine add, the various technological method such as hydraulic pressure and mechanical spinning to be to manufacture bellows.Minimum inside nominal diameter is 2 millimeters, and maximum inside nominal diameter can reach 400 ~ 500 millimeters, even has latus rectum to be the huge bellows of lO rice.Minimum l ~ 2 of ripple number, can reach continuous hundreds of, several thousand at most, even several ten thousand.From the significance of bellows as metallic hose body, the development of metal bellows, also just means the development of metallic hose.
Subsequently, people are the material such as rubber, plastics or nylon on bellows outer surface is coated, and the net that armouring is made up of wire or metal tape, converts various joint form.For the difference adapted under various service condition requires the metallic hose creating various ways.
Summary of the invention
The object of the present invention is to provide a kind of bellows, there is bearing capacity, the high-low temperature resistant power that can improve flexible pipe finished product, extend working life of body, the feature such as to reduce costs.
Technological scheme of the present invention is: a kind of bellows, described bellows comprises outermost surface, mesosphere and the outermost surface bonding layer between mesosphere, described outermost surface is acrylic plastics, mesosphere is beryllium bronze, the bonding layer of described outermost surface between mesosphere is high-temperature-resistant adhesive, described acrylic plastics accounts for the 40%-50% of the overall component of bellows, described beryllium bronze accounts for the 54%-56% of the overall component of bellows, and described high-temperature-resistant adhesive accounts for the 1%-2% of the overall component of bellows.
In a preferred embodiment of the present invention, described high-temperature-resistant adhesive comprises inorganic oxide copper and inorganic nano.
In a preferred embodiment of the present invention, described acrylic plastics accounts for 44% of the overall component of bellows, and described beryllium bronze accounts for 54% of the overall component of bellows, and described high-temperature-resistant adhesive accounts for 2% of the overall component of bellows.
A kind of bellows of the present invention, has bearing capacity, the high-low temperature resistant power that can improve flexible pipe finished product, extends working life of body, the feature such as to reduce costs.
Embodiment
Be described in detail below in conjunction with to preferred embodiment of the present invention, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
In one embodiment, a kind of bellows of the present invention, described bellows comprises outermost surface, mesosphere and the outermost surface bonding layer between mesosphere, described outermost surface is acrylic plastics, mesosphere is beryllium bronze, the bonding layer of described outermost surface between mesosphere is high-temperature-resistant adhesive, described acrylic plastics accounts for the 40%-50% of the overall component of bellows, described beryllium bronze accounts for the 54%-56% of the overall component of bellows, and described high-temperature-resistant adhesive accounts for the 1%-2% of the overall component of bellows.
Further illustrate, described high-temperature-resistant adhesive comprises inorganic oxide copper and inorganic nano, described acrylic plastics accounts for 44% of the overall component of bellows, and described beryllium bronze accounts for 54% of the overall component of bellows, and described high-temperature-resistant adhesive accounts for 2% of the overall component of bellows.
Further illustrate, high temperature resistant inorganic tackiness agent is a kind of high temperature resistant inorganic nanocomposite binders utilizing inorganic nano material to make through polycondensation reaction, by the screening to composition proportion and preparation technology parameter, to obtain Bond be pH value is neutral suspension/dispersion, not only cohesive force is strong and to metallic matrix non-corrosiveness, and good adhesive property and corrosion resistance can be kept, long service life under high temperature again.
High temperature resistant inorganic tackiness agent is easy to use; can be used for the directly bonding of exotic material; coating can directly the high temperature matrix surface spraying of 400-1000 DEG C; while moisture evaporation; coating can stick to matrix surface instantaneously; the high temperature resistant protective coating even compact formed, thermal shock resistance is good, and protection effect is remarkable.
Adhesion is firm, can so firm for Inorganics that to stick together, be not easy separately, coating heatproof can reach 1800 DEG C, and thermostable heat-isolating coating also has the features such as insulation, waterproof, heat-insulation and heat-preservation, protection against the tide, fire-retardant, wear-resisting, acid resistant alkali, lightweight, easy construction, long service life in addition.
Acrylic plastics have matter firmly, not easily fragmentation, highly transparent, good weatherability, be easy to dyeing and the feature such as shaping, become widely used transparent plastic material.Plexiglass is classic transparent plastic, and transmittance >92% is lightweight, relative density 1.19, is only the half of unorganic glass.Plexiglass is thermoformable is processed into various shape, and machinable boring, engraving such as to be milled at the machining the secondary operations such as bonding, application printing, gold stamping, the hot stamping embossing of dyeing, metal evaporation can become a clock goods.But PMMA quality is more crisp, is soluble in organic solvent, surface hardness is inadequate, and easy snag, can require the transparent configuration part of some strength, as lubricating cup, car light, Meter Parts, and optical lens, decoration gift etc.Add some additives inside to increase to its performance, as heat-resisting, rub resistance etc.This material is widely used in Advertisement label, architectural glazings, lighting fixture, instrument and apparatus, optical lens, safty shield, household utensils and aircraft cockpit, porthole and bullet proof glass etc.The invention provides a kind of bellows, there is bearing capacity, the high-low temperature resistant power that can improve flexible pipe finished product, extend working life of body, the feature such as to reduce costs.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
