Lapho ukhetha ithangi le-scuba, abahlukahlukene bavame ukudinga ukunquma phakathi kwezinketho zensimbi ne-aluminium. Uhlobo ngalunye lunesethi yalo yezinzuzo nokucatshangelwa, okwenza ukukhetha kuncike ezidingweni zomuntu ngamunye kanye nezimo zokutshuza.
Ukuqina Nokuphila Isikhathi Eside
Amathangi ensimbi aziwa ngamandla awo nokuqina kwawo. Ziyakwazi ukumelana nomonakalo njengama-dents kanye nokuklwebheka, okuzenza zibe inketho ehlala isikhathi eside uma zigcinwe kahle. Nokho, amathange ensimbi asengozini yokugqwala, ikakhulukazi ezindaweni ezinamanzi anosawoti, futhi adinga ukunakekelwa ngokucophelela ukuze agweme ukugqwala. Ukuhlolwa okuvamile nokunakekelwa okufanele kunganweba kakhulu isikhathi sokuphila sethangi lensimbi, okungenzeka sifike eminyakeni engama-50.
Ngakolunye uhlangothi, amathangi e-aluminium awajwayele ukugqwala, okuwenza alungele ukutshuza emanzini anosawoti. Nakuba esengozini yokungenwa ama-dent kanye nokuklwebheka ngenxa yokwakheka kwawo kwensimbi ethambile, amathangi e-aluminium asengakwazi ukunikeza iminyaka eminingi yokusetshenziswa okuthembekile ngokulungiswa okufanele. Lawa mathangi ngokuvamile ahlolwa nge-hydrostatic njalo eminyakeni emihlanu futhi ahlolwe njalo ngonyaka ukuze kuqinisekiswe ukuphepha nokusebenza.
Isisindo kanye ne-Buoyancy
Isisindo kanye ne-buoyancy yizici ezibalulekile ekukhetheni ithangi elifanele le-scuba. Amathangi ensimbi, naphezu kokuba esindayo emhlabeni, awanyakazi kangako ngaphansi kwamanzi. Lokhu kubhuqa okungekuhle kuvumela abatshuzi ukuthi bathwale isisindo esengeziwe esincane emabhandeni abo, okungaba yinzuzo ngesikhathi sokutshuza. Nokho, isisindo singaba nzima uma uthutha ithangi uliyisa noma ulisusa endaweni yokutshuza.
Amathangi e-aluminium, ngokuphambene, alula emhlabeni, okwenza kube lula ukuwaphatha nokuthutha. Ngaphansi kwamanzi, ziqala zi-buoyant ezimbi kodwa ziba zinhle njengoba kusetshenziswa umoya. Lesi sici sidinga abatshuzi ukuthi balungise izisindo zabo ngokufanele ukuze balondoloze ukusimama okungathathi hlangothi phakathi nokutshuza. Ukushintsha kwe-buoyancy njengoba ithangi lithulula kungagqama kakhulu ngamathangi e-aluminium, okungenzeka kuthinte ukuzinza kwe-dive.
Amandla nengcindezi
Uma kuziwa kumthamo womoya nokucindezela, amathangi ensimbi avame ukubamba inzuzo. Ngokuvamile zingabamba ukucindezela okuphezulu (kufika ku-3442 psi) uma kuqhathaniswa namathangi e-aluminium, ngokuvamile aphuma cishe ku-3000 psi. Lo mthamo ophakeme usho ukuthi amathangi ensimbi angagcina umoya omningi endaweni encane, ehlangene, ezuzisa kakhulu ukutshuza okude noma okujulile.
Amathangi e-aluminium, ngenkathi enikeza umthamo omncane, aseyinketho edumile phakathi kwabatshuzi bezokungcebeleka ngokusebenziseka kwawo kanye nokusebenza kahle kwezindleko. Amathangi e-aluminium ajwayelekile ngokuvamile afika ngosayizi wama-cubic foot angu-80, anele ukutshuza okuningi kokuzijabulisa.
Izindleko
Izindleko zingenye into ebalulekile kubatshuzi abaningi. Amathangi e-aluminium ngokuvamile athengeka kakhulu kunamathangi ensimbi. Leli phuzu lentengo eliphansi libenza babe ukukhetha okuhle kakhulu kwabatshuzi kubhajethi noma labo abatshuza kancane. Naphezu kokuba eshibhile, amathangi e-aluminium awafaki engozini ukuphepha noma ukusebenza, okuwenza abe inketho ethembekile yabatshuzi abaningi.
Isiphetho
Womabili amathangi e-scuba ensimbi ne-aluminium anezinzuzo zawo eziyingqayizivele kanye nezithiyo. Amathangi ensimbi aqinile, anikeza amandla aphezulu, futhi agcina ukuvunguza okungalungile, okuwenza alungele ukutshuza emanzini abandayo. Amathangi e-Aluminium athengeka kakhudlwana, kulula ukuwahambisa, futhi amelana nokugqwala, okuwenza afanelekele ukuzilibazisa nokutshuza emanzini anosawoti.
Ukukhetha ithangi elifanele kuncike ezidingweni zakho ezithile zokutshuza, isabelomali, namandla okulungisa. Ngokuqonda lo mehluko, abatshuzi bangenza isinqumo esinolwazi esithuthukisa ukuphepha kwabo nokujabulela kwabo ngaphansi kwamanzi.
