Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Fig. 1 is the schematic representation of the gas cylinder of specific embodiment of the present invention.
Embodiment
As shown in Figure 1, this gas cylinder that is used for the fortune car is a kind of steel inner bag glass fibre hoop winding gas cylinder, and volume uses working pressure between 25MPa ~ 35MPa at 200 L ~ 400L.Gas cylinder comprises the shell portion that is positioned at the middle part, lays respectively at two bottlenecks at two ends and the end socket of connecting cylinder figure and bottleneck, and its wall comprises from inside to outside successively: the inner bag 1 that is formed from steel; The combination coating of processing by polyurethane material 2; By the composite layer 3 that glass fibre-the epoxy systems composite material is processed; Outer protective film.
Inner bag 1 is shaped by the mode of chrome molybdenum steel pipe with spinning closing-in, and it provides the space for storing compressed natural gas, directly contacts with filling medium, plays the sealing effect of holding one's breath, and bears the pressure of a part.Inner bag 1 need be heat-treated after shaping, and step is: inner bag is put into oven, be heated to 860 ℃ to 910 ℃ and holding time 40 minutes to 60 minutes; In water-soluble quenching liquid, cool off, carry out temper then.This heat treatment mode can improve the mechanical property of inner bag significantly, and the metallographic structure of inner bag is a tempered sorbite after the heat treatment, and the overall performance good uniformity is no more than 40MPa with intraindividual tensile strength deviation between the inner bag individuality, and specific elongation reaches more than 12%.
Go out to satisfy the screw thread of size and required precision on the inner bag 1 with lathe in machining.
Preservative treatment is carried out on the surface of inner bag 1, adopts the mode of electrostatic spraying to spray paint, and has effectively guaranteed uniformity, conformity and the good glossiness of inner bag 1 surperficial paint film.
Form for adopting electrostatic spraying technology that polyurethane powder coating evenly is sprayed at inner bag 1 surface in conjunction with coating 2, thickness is greater than 60 μ m.Adopt polyurethane material as combining coating 2, thickness is big and guaranteed the combining closely property and the adhesive property of inner bag and composite layer to make the stressed coordination more of inner bag and composite layer, and adhesive shear strength is greater than 40MPa.
Composite layer 3 is used the glass fibre that has flooded resin matrix to carry out hoop and is entwined by the outer surface at inner bag 1, soaks on the glass fibre that resin matrix is arranged during winding to be applied with preset tension force.In concrete the winding; At first load onto at the two ends of inner bag 1 and Stetch Wrapping Machine, the supporting frock of curing oven, behind high strength glass fiber insulating varnish matrix, preset certain force of strain is wrapped on the cylindrical shell of inner bag 1; Design shop layer thickness according to gas cylinder; Hoop twines, multilayer covers, and the centre can have 2 to 6 layers for medial axis 60 ° to the 80 ° spirals of one-tenth with respect to said gas cylinder are entwined, and other each layers are entwined for hoop.Fiber can carry the axial strength of a part, the working life of effectively improving gas cylinder like this.
Gas cylinder after the winding is cured by following mode: gas cylinder is put into continuous curing oven; In first warm area, second warm area and triple temperature region, be cured successively; The temperature of first warm area is lower than second warm area; The temperature of said triple temperature region is lower than first warm area and second warm area, and the composite layer after guaranteeing like this to solidify is progressively lowered the temperature, and avoids direct air cooling to cause resin fragility to increase; In solidification process, keep the horizontal rotation of gas cylinder, can access gas cylinder surface quality preferably like this.Concrete, the first warm area temperature is 90 ℃ to 110 ℃, and the second warm area temperature is 130 ℃ to 140 ℃, and the triple temperature region temperature is 70 ℃ to 90 ℃, and total curing time is between 4.5 hours to 6.5 hours.
