Gas cylinder is a kind bear press facility, can repeat below normal environment aerate use come the movable type pressure vessel of full-dress permanent gas, liquefacient gas or deliquescent gas. As gas cylinder light quantify, the development requirement that safety changes, the special type gas cylinder that makes by composite material becomes a kind of of gas cylinder main form gradually.
It is good that gas cylinder of composite material special type has light qualitative excel in, fatigue resistance, corrosion resistance is strong, can make the gas cylinder with complex form. Compare with photograph of metallic gas cylinder, the special type gas cylinder that composite material makes has the following advantage:
- Quality is light;
- Laden work life is long;
- Security is high, have the fatigue failure mode that before blowing up, divulges first;
- Operating costs is low, cycle is short.
Current, gas cylinder of composite material special type applies extensively at aerospace domain, fire control equipment, respirator gas cylinder, compress natural gas or Chu Qing gas cylinder to wait. Since composite material gas cylinder realizes application oneself, its enhanced fiber to experience fiber of fibre glass, fragrant black silk ribbon, carbon fiber early or late the development of 3 acting material. Gas cylinder of carbon fiber composite material is used twine craft treatment to make. Twine in fiber shape in the process, carbon fiber silk bundle macerate colophony glue falls in tensional action around rotate arbor happens ceaselessly twine, form gradually cylindrical structure. Carbon fiber is twined include to work the law is twined and wet twine. Twine at working a way relatively, wet voluble manufacturing cost is lower, product air-tightness is good, have apparent cost advantage, because this is the treatment craft with the at present most commonly used bottle of high-pressured gas storage.
Fiber is twined in use colophony gum includes to heat up solid sex colophony and thermoplastic colophony two kinds big, epoxy resin is the mainest matrix colophony type in glue of colophony of hot solid sex. A few recommend to twine the commonly used foundation colophony in craft in fiber here:
- NPEL-128
Annulus oxygen equivalent (G/eq) : Viscosity of 184 ~ 190 (Cps/25 ℃ ) : Product of 12000 ~ 15000 explains: Extensive uses epoxy resin of A of standard type double phenol.
- NPEL-127
Annulus oxygen equivalent (G/eq) : Viscosity of 176 ~ 184 (Cps/25 ℃ ) : Product of 8000 ~ 11000 explains: NPEL-127 is a kind of epoxy resin that did not add thinner, have inferior viscosity than NPE-128 colophony, but similar property is had after reaction.
- NPEF-170
Annulus oxygen equivalent (G/eq) : 160~ 180 viscosity (Cps/25 ℃ ) : 2000~ 5000 product explains: F of standard type double phenol epoxy resin. In recent years, according to the adjustment of international energy new policy, because gas cylinder of composite material special type is qualitative light, security is high, carry go to the lavatory and the advantage of managing the sources of energy, become the ideal carrier that gas stores and carries. As the craft that make optimize ceaselessly, the optional choose sex of recipe raw material is increasing, gas cylinder of composite material special type also won wider and wider application.
