HDPE or nylon PA or multi-layer bonded structures, and its volume is 46-450L, operating pressure 20MPa-70MPa, in plastics
The volume and operating pressure of courage are applied widely, and size flexibility ratio is big.
In order to make those skilled in the art that the present invention be more clearly understood, the production process of the present invention is done one below
Briefly illustrate.
First, (can be one in high density polyethylene (HDPE) (HDPE) or nylon (PA) or multi-layer bonded structure using plastics
Kind) in a manner of blowing or rotational moulding by 3 machine-shaping of plastic inner container, for storage compressed natural gas either hydrogen or other gases
Space is provided, with filling physical contact between media, plays sealing and holds one's breath, do not undertake pressure.
After plastic inner container 3 is molded, its surface is surface-treated by flame method, reaches increase plastic inner container surface
Surface tension purpose, approach the surface tension of itself and glue system, about 30 dynes of the surface tension of general plastics, passes through
Its surface tension is improved to more than 40 dynes (curing rear surface tension force with glue system to approach) after flame method surface treatment, make
Both can preferably combine at interface, and method is to use about 1800 ° of flames, and moment handles 3 surface of plastic inner container,
Improve its surface energy.
When plastic inner container 3 after surface treatment, be exactly that metal bottleneck 1 and metal bottle tail 2 are installed in next step, the purpose is to increase
Add the intensity of plastic inner container bottle tail and bottleneck, particularly 3 bottleneck intensity of reinforced plastics liner and sealing performance.By gold on lathe
Belong to bottleneck 1 and metal bottle tail 2 processes required screw thread on request, metal bottleneck 1 and metal bottle tail 2 are respectively charged into end socket groove
With sealing groove, it is completed rear liner and integrally carries out sealing propertytest, liner No leakage under internal pressure 0.2Mpa, ensures sealing
Property, meet the requirements permeability of the gas in bottle.
After overall liner carries out seal tightness test, compressed air is filled inside plastic inner container 3, prevents plastic inner container 3
Deform in Wiring apparatus and winding process is installed on.
Carbon fiber strength layer group 4 is wrapped in the outer surface of plastic inner container 3, using the carbon fiber impregnated of resin matrix to modeling
Expect liner 3 carry out successively outside interior horizontal winding, longitudinally wound and spiral winding, form carbon fiber laterally winding intensity respectively
Layer 41, carbon fiber wind strength layer 43 longitudinally wound strength layer 42, carbon fiber spiral, and the carbon that when winding is impregnated with resin matrix is fine
Default tension force is applied with dimension.In specific winding, loaded onto first at the both ends of plastic inner container 3 supporting with wrapping machine, curing oven
Frock, after impregnated carbon fiber resin matrix, preset certain tension force and be wrapped in cylinder and the end socket sealing of plastic inner container 3
On, according to the design overlay thickness of the compound gas bomb of high pressure, by carrying out horizontal winding successively outside interior, being twined longitudinally wound with spiral
Around multilayer covering, alternately winds, and such carbon fiber balanced can carry axial strength and circumferential intensity, and gas cylinder is effectively ensured
Service life.
Since full composite high pressure gas bomb is partially exposed in air after using installation, carbon fiber strength layer group
4 need effective manner influences the performance of gas cylinder to protect to prevent the composite material layer surface from being corroded and collided with.
For this reason, full composite high pressure gas storage bottle surface is equipped with glass fibre protective layer group 5, it uses glass fiber tape some tension to take spiral shell
Rotation winding and the horizontal alternate mode of winding are wrapped in 4 outer surface of carbon fiber strength layer group, prevent the moisture and tool in air
The material for the matter that is corrosive corrodes above-mentioned composite layer outer surface.
After full composite high pressure gas bomb has wound carbon fiber strength layer group 4 and glass fibre protective layer group 5, in next step
It is to be cured, full composite high pressure gas bomb is put into curing oven, and cured in warm area, when full composite high pressure gas storage
Bottle takes out after being cooled to certain temperature after the completion of curing again in warm area out of curing oven, and the cooling temperature is less than in curing oven first
The temperature of warm area and the second warm area, so can guarantee that the composite layer after curing progressively cools down, and avoid Direct Air-Cooled increase tree
Fat brittleness；Bottleneck and bottle tail horizontal support in the curing process, make full composite high pressure gas bomb be rotated horizontally in curing oven, this
Sample can obtain protecting liner indeformable while can obtain preferable the surface of gas cylinder quality again.Wherein, the temperature of warm area is 90 DEG C,
Between total hardening time is when 4.5 hours are small to 10,
In the curing process, aathermoset resin system crosslinks full composite high pressure gas bomb, assigns carbon fiber strength layer
4 a degree of anti-shearing, anticorrosive, chemical stabilities of group and transmission fibre stress etc..Make glass fibre protective layer group 5 at the same time
Shaping, it is injury-free with the carbon fiber strength layer group 4 inside ensureing full composite high pressure gas bomb when being impacted and being corroded, keep away
The performance for exempting from full composite high pressure gas bomb is destroyed, so as to extend the service life of full composite high pressure gas bomb.
After full composite high pressure gas bomb cures, the water pressure test and inner wall drying and processing are carried out to it, pass the test is simultaneously
And it can come into operation after being disposed.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit the protection model of the present invention
Enclose, as long as the present invention body design thought and that mentally makes have no the change of essential meaning or polishing, it is solved
Technical problem it is still consistent with the present invention, should be included in protection scope of the present invention within.
