I-Carbon FiberI-Winding Composite Pressure Vessel yinqanawa enodonga olucekeceke olunelinen etywiniweyo etywiniweyo kunye nomgangatho ophezulu we-fiber-nxeba umaleko, owenziwe ikakhulu kukujija kwefiber kunye nenkqubo yokuluka. Xa kuthelekiswa neempahla zentsimbi zendabuko, i-liner ye-composite pressure vessels isebenza njengokugcinwa, ukutywinwa kunye nokukhusela ukubola kweekhemikhali, kunye ne-composite layer isetyenziselwa ukuthwala umthwalo wangaphakathi. Ngenxa yamandla athile aphezulu kunye nokuyilwa kakuhle kwee-composites, iinqanawa zoxinzelelo ezidibeneyo aziphuculanga kakhulu umthamo wazo wokuthwala umthwalo, kodwa zinciphise kakhulu ubunzima beenqanawa xa kuthelekiswa neenqanawa zoxinzelelo zentsimbi.
Uluhlu lwangaphakathi lwesitya soxinzelelo lwe-fiber-inxeba ubukhulu becala luluhlu lwe-liner, umsebenzi walo oyintloko kukusebenza njengesithintelo sokutywinwa ukukhusela ukuvuza kweegesi eziphezulu zoxinzelelo okanye ulwelo olugcinwe ngaphakathi, kwaye ngexesha elifanayo ukukhusela i-fiber-nxeba layer. Olu luhlu aluyi kugqweswa yimpahla egcinwe ngaphakathi kunye noluhlu lwangaphandle luyi-fiber-nxeba layer eqiniswe nge-matrix ye-resin, eyona nto isetyenziselwa ukunyamezela imithwalo eninzi yoxinzelelo kwinqanawa yoxinzelelo.
1. Ukwakhiwa kweenqanawa zoxinzelelo lwe-fiber-inxeba
Kukho iindlela ezine eziphambili zesakhiwo semikhumbi yoxinzelelo oludibeneyo: i-cylindrical, i-spherical, i-annular kunye ne-rectangular. Isitya se-cylindrical sinecandelo le-cylinder kunye neentloko ezimbini. Iinqanawa zoxinzelelo lwesinyithi zenziwe zibe ziimilo ezilula ezinokugcinwa kwamandla okugqithisileyo kwicala le-axial. Iinqanawa zeSpherical zineengcinezelo ezilinganayo kwi-warp kunye ne-weft directions phantsi koxinzelelo lwangaphakathi kwaye isiqingatha soxinzelelo olujikelezayo lweenqanawa ze-cylindrical. Amandla ezinto zetsimbi alinganayo kuwo onke amacala, ngoko ke isitya se-spherical esenziwe ngetsimbi senzelwe amandla alinganayo, kwaye sinobunzima obuncinci xa umthamo kunye noxinzelelo ziqinisekile. I-Spherical container force state yeyona ifanelekileyo, udonga lwesikhongozeli lunokwenziwa lube lolona luncinci. Nangona kunjalo, ngenxa yobunzima obukhulu bokwenza izikhongozeli ezingqukuva, ezisetyenziswa ngokubanzi kwiziphekepheke kunye nezinye iziganeko ezikhethekileyo. Isingxobo sendandatho kwimveliso yoshishino sinqabile kakhulu, kodwa kwezinye iimeko ezithile okanye sidinga esi sakhiwo, umzekelo, izithuthi zendawo ukuze zisebenzise ngokupheleleyo indawo elinganiselweyo, ziya kusebenzisa esi sakhiwo sikhethekileyo. Isikhongozeli esibuxande sifuneka ikakhulu ukudibana xa isithuba sinqongophele, sandise ukusetyenziswa kwendawo kunye nokusetyenziswa kwezakhiwo, ezinjengeemoto zetanki eziluxande, iimoto zetanki zikaloliwe, njl.
Ubunzima besakhiwo seindibaniselwanoisitya soxinzelelo ngokwaso, utshintsho olukhawulezileyo lobunzima bentloko kunye nentloko, ubukhulu obuguquguqukayo kunye ne-angle yentloko, njl., kuzisa ubunzima obuninzi kuyilo, uhlalutyo, ukubala kunye nokubumba. Ngamanye amaxesha, iinqanawa zoxinzelelo ezidibeneyo azifuni nje ukuba zenze amanxeba kwii-engile ezahlukeneyo kunye nesantya esiguqukayo kwisahlulo sentloko, kodwa kufuneka samkele iindlela ezahlukeneyo zokujija ngokwezakhiwo ezahlukeneyo. Ngelo xesha, impembelelo yezinto eziphathekayo ezifana ne-friction coefficient kufuneka ziqwalaselwe. Ke ngoko, luyilo oluchanekileyo nolufanelekileyo lolwakhiwo olunokukhokela ngokuchanekileyo inkqubo yokuveliswa koxinzelelo oluhlanganisiweyo, ukuze kuveliswe iimveliso zenqanawa ezidityanisiweyo ezilula ezihlangabezana neemfuno zoyilo.
2. Izinto eziphathekayo zesitya soxinzelelo lwe-fiber-nxeba
Njengeyona nxalenye iphambili ethwele umthwalo, umaleko wokujija ifayibha kufuneka ube namandla aphezulu, imodyuli ephezulu, ingxinano ephantsi, uzinzo lwe-thermal kunye nokumanzisa kakuhle kwe-resin, kunye nokuqhubekeka kakuhle kokujika kunye nokuqina kwe-fiber bundle. Iintsinga zokuqinisa ezisetyenziswa ngokuqhelekileyo kwiinqanawa zoxinzelelo ezidibeneyo ezidibeneyo ziqukaiifayibha zekhabhoniiintsinga zePBO,imicu yepolyamine enevumba elimnandi, kunye neentsinga ze-UHMWPE.
