Description
Technical field
The utility model is related to a kind of high pressure storage and transportation gas cylinders, belong to pressure vessel technology field, more particularly to a kind of fiber
Wind the storage and transportation gas cylinder of plastic inner container.
Background technology
With being constantly progressive for new energy technology, adaptable energy storaging and transport technology also obtains considerable hair in recent years with this
Exhibition is also significantly increased for containing the demand of the energy medium especially pressure cylinder of gas medium both at home and abroad, but domestic at present
The gas cylinder overwhelming majority that market is applied to high pressure gas storage and transportation is all-metal or the fiber winding enhancing gas with metal inner tube
Bottle.But steel cylinder is there are complex forming technology, quality is big, transport is inconvenient, perishable, it is visual not have, uses process intermediate frequency
There is the defects of explosion accident generation.Fiber, which winds plastic inner container composites gas cylinder, has that light-weight, intensity is high, corrosion-resistant, no
Explosion, see-through, service life is long, and maintenance cost is low to wait excellent properties.Country it is increasingly stringent to gas cylinder safely performance requirement,
In the case that constancy of volume gas cylinder weight demands are increasingly lighter, fiber winds liner composites gas cylinder due to combining high-performance
The characteristics of fiber and special plastic, under the premise of ensureing gas cylinder safely performance, weight compare metal cylinder reduce 60%
More than, therefore there is higher volume to weight ratio, and gas cylinder has good corrosion resistance and does not explode when fire occurs,
Longer escape time can be left to people, therefore, it has become substitute conventional metals steel cylinder and newly becoming with broad prospect of application
Gesture.
According to European Union《Removable/full wound composite gas cylinders of EN12245》Standard, composites gas cylinder will pass through vacuum
Cycle adjusts detection, at ambient temperature empties gas in gas cylinder, so that its pressure is down to absolute 0.2bar and keep this state 1
Minute, the pressure in gas cylinder is then risen into atmospheric pressure, repeats above step 50 times.Nothing inside liner is required after cyclic test
Damage, degumming, folding.
Due to the bad mechanical property of plastics, the manufacturing cost of comprehensive consideration plastic inner container can meet the plastics of economic indicator
Liner will produce degumming phenomenon after carrying out vacuum cycle detection, be extremely difficult to European Union's test stone.Simultaneously as plastic inner container
The material of generally use PE plastic productions, fiber-reinforced layer is generally glass fibre or carbon fiber, and the two type is different, two kinds of materials
It can not intimately be combined between material.When temperature, pressure and other environmental aspects vary widely, different de- of degree also will produce
Glue phenomenon.
In order to solve problem above, improvement direction be by plastic inner container closely with the fiber-reinforced layer knot of stable structure
It closes, depends on fiber-reinforced layer and improve the stress intensity of plastic inner container.And the interface of plastic inner container and fiber-reinforced layer is difficult knot
It closes, there are mainly two types of solutions for industry at present.
Scheme one is that plastic inner container is carried out high temperature to burn carbonization treatment, improves the surface texture of plastics, increases after carbonization
The frictional force and adhesive force of plastic inner container outer wall and fiber winding layer, but result can not meet testing conditions.Scheme is second is that moulding
Expect the bonding agents such as inner bladder outer wall brushing polyurethane, liner and fiber winding layer is bonded together, due to two kinds of material difference nothings
Method intimately combines, and such method still can not meet testing conditions.So so far, plastic inner container and fiber winding layer interface
Combination this critical issue effectively solved not yet.
Utility model content

Full of resin.
As the improvement of the utility model, on the cross section of the plastic inner container, the area of the embedded division be more than or
Equal to the area of the exposed division.
As the improvement of the utility model, the wedge shaped structure of embedded division.
As the improvement of the utility model, the material of the fiber-reinforced layer and the fibrous web-like binder course is fibre of the same race
Dimension.
As the improvement of the utility model, the material of the fibrous web-like binder course is glass fibre.
As the improvement of the utility model, the material of the fibrous web-like binder course is fibrous mesh cloth.
As the improvement of the utility model, protective layer is provided with outside the fiber-reinforced layer.
As the improvement of the utility model, the protective layer is flexible material.
Plastic inner container and web are made since fibrous web-like binder course is heated into plastic inner container using above-mentioned technical proposal
Shape binder course combination is very secured；Fibrous web-like binder course includes embedded division and exposed division, fibre on the cross section of plastic inner container
Dimension enhancement layer is wrapped on the exposed division of fibrous web-like binder course and the outer wall of plastic inner container, in fiber-reinforced layer, fibrous web-like
Between binder course and the outer wall of plastic inner container, it is full of resin, resin is embedded with fibrous web-like binder course by fiber-reinforced layer and thereon
Plastic inner container firmly combine；It is used as transition turn by the way that fibrous web-like binder course is arranged between plastic inner container and fiber-reinforced layer
The combination of layer is connect, hot melt has been respectively adopted in the contact surface of three, resin adds winding, to make plastic inner container and fiber-reinforced layer
In conjunction with very securely, after vacuum cycle detection and when temperature, pressure and other environmental aspects vary widely, will not produce
Raw degumming phenomenon.
