#I-Polyurethane ye-Thermoplastic(TPU) iyi-elastomer esebenza kahle kakhulu esetshenziswa kakhulu emishinini engaphansi kwamanzi ngenxa yenhlanganisela yayo eyingqayizivele yamandla okusebenza, ukuguquguquka, ukumelana namakhemikhali, kanye nokuqina kwe-hydrolytic. Isebenza kahle kakhulu kunezinye izinto zendabuko ezifana ne-PVC ne-Hypalon ezindaweni zasolwandle, okwenza kube yinto ekhethwayo yezinhlelo ezibalulekile ezingaphansi kwamanzi. ## Izinzuzo Eziyinhloko zeI-TPUUkusetshenziswa Ngaphansi Kwamanzi – **Ukumelana Okuhle Kakhulu Kwamanzi**: Igcina ubuqotho besakhiwo kanye nezakhiwo zemishini ngemva kokucwiliswa isikhathi eside emanzini olwandle noma emanzini ahlanzekile. – **Ukumelana Okuhle Kwamakhemikhali**: Imelana nokugqwala kwamanzi anosawoti, uwoyela, uphethiloli, kanye nokuwohloka kwamagciwane. – **Ukusebenza Okuphezulu Kwamakhemikhali**: Inikeza amandla avelele okubamba, ukumelana nokudabuka, kanye nokumelana nokuguguleka. – **Ukubekezelela Izinga Lokushisa Elibanzi**: Ihlala iguquguquka kusukela ku--50°C kuya ku-80°C, ifanele izindawo zasolwandle ezisenyakatho kuya kwezishisayo. – **Ukucutshungulwa Okuhle**: Ingashiselwa, ibunjwe, noma igqunywe ezindwangu, okuvumela ukukhiqizwa okuguquguqukayo. – **Isilinganiso Esiphansi Sokuvuvukala**: Inciphisa izinguquko zobukhulu lapho ivezwa emanzini namafutha. ## Izicelo Eziyinhloko Emishinini Yangaphansi Kwamanzi ### 1. Amakhebula Angaphansi Kwamanzi Nasemanzini I-TPU isetshenziswa kakhulu njengezinto ze-sheath yangaphandle yamakhebula wamandla angaphansi kwamanzi kanye nokuxhumana. – **Umsebenzi**: Ihlinzeka ngokuvikelwa okuqinile ekugqwaleni kwamanzi olwandle, ukuguguleka, kanye nomonakalo wemishini ngesikhathi sokufakwa nokusebenza. – **Izici**: Ukuguquguquka okuphezulu kokugoba okuphindaphindiwe, ukumelana okuhle kakhulu kwe-UV, kanye nokuqina kwesikhathi eside ezindaweni ezijulile zolwandle. – **Umklamo**: Ngokuvamile kuqiniswa ngemicu ye-aramid (i-Kevlar) ukuze kuthuthukiswe amandla okuthambekela. ### 2. Imishini Yokuphepha Nokuhlangula Yasolwandle EfuthwayoI-TPUIzindwangu ezimboziwe ziyindinganiso yegolide yemishini yesimanje esindisa impilo efuthwayo. – **Amavesti Okuphila Nama-Raft Afuthwayo**: Inikeza ukugcinwa komoya okuhle kakhulu, iqinisekisa ukuntanta nokuphepha ezimweni eziphuthumayo. – **Amadivayisi Okuntanta Empi**: Asetshenziswa ezinhlelweni zokuthunyelwa ngokushesha ukuze kutholakale abasebenzi, amelana namanzi anosawoti, isihlabathi, kanye namazinga okushisa aphezulu. – **Inzuzo**: Imithungo eshibilikayo idala amalunga aqinile, athembekile kunezinye izindlela ezinamathele. ### 3. Imishini Yomsindo Ne-Sonar Engaphansi Kwamanzi I-TPU isebenza njengento ebalulekile yokuvala i-capsulant kanye nezinto zokuvikela zama-transducer e-sonar. – **Ukuvala i-capsulation**: Ivikela izingxenye ze-elekthronikhi ezizwelayo ekungeneni kwamanzi olwandle ngenkathi igcina ukubonakala kwe-acoustic. – **Izidingo Zezinto**: Ukuvuvukala okuphansi emanzini olwandle kanye namafutha e-paraffin (asetshenziswa njengendawo yokugcwalisa), amandla aphezulu omshini, kanye nokumelana nokucindezeleka isikhathi eside. – **Ukuxuba**: Izingxube ze-TPU/NBR zivame ukusetshenziselwa ukunciphisa ukuvuvukala nokuthuthukisa ukusebenza. ### 4. Amarobhothi Angaphansi Kwamanzi Nezinzwa Izinto ze-TPU ezithuthukisiwe zivumela ukuthuthukiswa kobuchwepheshe bokuzwa ngaphansi kwamanzi besizukulwane esilandelayo. – **Izinzwa Zokuthinta Eziguquguqukayo**: Amafilimu e-TPU anezimbobo asetshenziswa kuzinzwa zokuthinta ezisebenza ngokwazo, ezilinganiselayo ekucindezelweni kwama-manipulators e-ROV. – **Izinzuzo**: Isakhiwo esivulekile esinezimbobo sivumela ukungena kwamanzi olwandle, kufezwe ukulingana kwengcindezi ye-hydrostatic, kuvumela ukusebenza okuzinzile ekujuleni okukhulu. – **Umsebenzi**: Ithola ukuthungwa kwezinto, ubulukhuni, kanye nesimo sokuphathwa okunembile ngaphansi kwamanzi. ### 5. Ama-Marine Bearings & Seals Izinhlanganisela ezisekelwe ku-TPU zilungele izinhlelo zokuthwala ezigcotshwe ngamanzi. – **Ama-Stern Tube Bearings**: Asetshenziswa ezinhlelweni zokuhambisa umkhumbi ngenxa yokumelana okuhle kakhulu nokuguguleka okuphansi ngaphansi kokugcotshwa kwamanzi. – **Izinhlanganisela**: Ziqiniswe nge-carbon fiber, i-graphene, noma i-UHMWPE ukuthuthukisa ukusebenza kwe-tribological. – **Inzuzo**: Okunye okungenakho ukugqwala esikhundleni sama-bearings ensimbi, kunciphisa izidingo zokulungisa. ### 6. Ukuvikelwa Kwepayipi Langaphansi Kolwandle Izembozo ze-TPU zinikeza ukuvikelwa kokugqwala nokuguguleka okungabizi kakhulu kwamapayipi angaphandle kolwandle. – **Ukusetshenziswa**: Zisetshenziswa kumapayipi angaphansi kolwandle ensimbi engagqwali, ikakhulukazi emajoyintini endololwane asengozini. – **Ukusebenza**: Zigcina ukunamathela okuqinile ngaphansi kokujikeleza kokushisa, zinciphisa kakhulu amazinga okuguguleka. – **Inzuzo**: Zilinganisela ukuqina kanye nokwenzeka kwezomnotho uma kuqhathaniswa nezinhlelo zokugqoka zensimbi eziyinkimbinkimbi. ### 7. Izikebhe Ezifuthwayo Nezindwangu Zamanzi Ezimbozwe yi-TPU ziguqula ukwakhiwa kwezikebhe zesimanje ezifuthwayo. – **Izinzuzo**: Zilula, zihlala isikhathi eside, azimelani ne-UV, futhi zinobungani nemvelo uma kuqhathaniswa ne-PVC. – **Ukukhiqiza**: Izembozo ezifakwe ngokushisa zakha amakamelo angangeni moya ngaphandle kwezinamathelisi ezinobuthi. – **Ukusebenza**: Zimelana nezimo ezinzima zasolwandle futhi zinikeza impilo yesevisi ende. ## Isiphetho Izakhiwo zezinto ezihlukile ze-TPU ziyenza ibe yinto ebalulekile ekwakhiweni nasekukhiqizweni kwemishini ethembekile, esebenza kahle ngaphansi kwamanzi. Ukuguquguquka kwayo, kusukela ekumbozweni okuguquguqukayo kuya ezingxenyeni zesakhiwo eziqinile, kuyaqhubeka nokushayela ukusungula izinto ezintsha kubuchwepheshe basolwandle, okuvumela ukusebenza okuphephile nokusebenza kahle ezindaweni ezingaphansi kwamanzi eziyinselele. Ungathanda ukuthi ngihlanganise lokhu kube yi-**isifinyezo sobuchwepheshe esifingqiwe** sombiko noma isethulo?
