izindaba

I-Carbon FiberI-Winding Composite Pressure Vessel iyisitsha esinezindonga ezincane esihlanganisa umugqa ovalwe nge-hermetically kanye nongqimba oluqinile lwe-fiber-nxeba, olwakhiwe kakhulu ngokusonteka kwefayibha kanye nenqubo yokweluka. Uma kuqhathaniswa nezitsha zokucindezela zensimbi zendabuko, i-liner yemikhumbi yokucindezela eyinhlanganisela isebenza njengesitoreji, ukuvala uphawu nokuvikelwa kokugqwala kwamakhemikhali, futhi ungqimba oluhlanganisiwe lusetshenziselwa ikakhulukazi ukuthwala umthwalo wangaphakathi wengcindezi. Ngenxa yamandla athile aphezulu kanye nokuklama okuhle kwezinhlanganisela, imikhumbi yokucindezela eyinhlanganisela ayizange ithuthukise kakhulu umthamo wayo wokuthwala umthwalo, kodwa futhi inciphise kakhulu isisindo somkhumbi uma kuqhathaniswa nemikhumbi yensimbi yensimbi evamile.
Isendlalelo sangaphakathi somkhumbi we-fiber-nxeba we-pressure ngokuyinhloko isakhiwo se-liner, umsebenzi wayo oyinhloko uwukukwenza njengesithiyo sokuvala ukuvimbela ukuvuza kwamagesi aphezulu noma uketshezi olugcinwe ngaphakathi, futhi ngesikhathi esifanayo ukuvikela ungqimba lwangaphandle lwe-fiber-nxeba. Lolu ngqimba ngeke ludliwe yizinto ezigcinwe ngaphakathi futhi ungqimba lwangaphandle luyi-fiber-nxeba layer eqiniswe nge-resin matrix, esetshenziselwa ikakhulukazi ukumelana nemithwalo eminingi yokucindezela emkhunjini wokucindezela.
1. Ukwakheka kwemithambo yomfutho we-fiber-nxeba
Kunezinhlobo ezine eziyinhloko zesakhiwo semikhumbi yokucindezela eyinhlanganisela: i-cylindrical, i-spherical, i-annular kanye ne-rectangular. Umkhumbi oyi-cylindrical uqukethe ingxenye yesilinda namakhanda amabili. Imikhumbi ye-Metal pressure yenziwa ibe yizimo ezilula ezinezinqolobane zamandla ezeqile ku-axial direction. Imikhumbi eyindilinga inezingcindezi ezilinganayo eziqondisweni ze-warp ne-weft ngaphansi kwengcindezi yangaphakathi futhi isigamu sokucindezeleka okujikelezayo kwemikhumbi eyi-cylindrical. Amandla ezinto zensimbi ayalingana kuzo zonke izinhlangothi, ngakho-ke isitsha esiyindilinga esenziwe ngensimbi senzelwe amandla alinganayo, futhi sinesisindo esincane lapho ivolumu nokucindezela kuqinisekile. I-Spherical container force state iyona ekahle kakhulu, udonga lwesitsha lungenziwa futhi lube thinnest. Kodwa-ke, ngenxa yobunzima obukhulu bokukhiqiza iziqukathi eziyindilinga, ngokuvamile ezisetshenziswa kumikhumbi-mkhathi nakwezinye izikhathi ezikhethekile. Isitsha sendandatho ekukhiqizeni izimboni asivamile kakhulu, kodwa kwezinye izikhathi ezithile noma sidinga lesi sakhiwo, isibonelo, izimoto zasemkhathini ukuze zisebenzise ngokugcwele indawo elinganiselwe, zizosebenzisa lesi sakhiwo esikhethekile. Isiqukathi esingunxande kufanele sihlangabezane kakhulu lapho isikhala sinqunyelwe, kwandiswe ukusetshenziswa kwendawo kanye nokusetshenziswa kwezakhiwo, njengezimoto zamathangi angama-rectangular, izimoto zamathangi kaloliwe, njll., iziqukathi ezinjalo ngokuvamile ziyiziqukathi ezinomfutho ophansi noma iziqukathi zomfutho womoya kanye nezimfuneko zekhwalithi zokukhanya okungcono kakhulu.
Ubunkimbinkimbi besakhiwo se-inhlanganiselaisitsha sokucindezela ngokwayo, ukushintsha okungazelelwe kobukhulu bekhanda nekhanda, ukushuba okuguquguqukayo kanye ne-angle yekhanda, njll., kuletha ubunzima obuningi ekwakhiweni, ukuhlaziya, ukubala nokubunjwa. Ngezinye izikhathi, imikhumbi yokucindezela eyinhlanganisela ayidingi nje kuphela ukulinyazwa ngama-engeli ahlukene kanye nezilinganiso zesivinini esiguquguqukayo engxenyeni yekhanda, kodwa futhi kudingeka isebenzise izindlela ezihlukene zokusonta ngokuvumelana nezakhiwo ezahlukene. Ngesikhathi esifanayo, ithonya lezici ezisebenzayo ezifana ne-friction coefficient kufanele icatshangelwe. Ngakho-ke, idizayini yesakhiwo efanele nenengqondo kuphela engaqondisa kahle inqubo yokukhiqiza emazombezombe yemikhumbi yokucindezela eyinhlanganisela, ukuze kukhiqizwe imikhiqizo yemikhumbi yokucindezela eyinhlanganisela engasindi ehlangabezana nezidingo zokuklama.
2. Izinto zomkhumbi we-fiber-nxeba wokucindezela
Njengengxenye eyinhloko ethwala umthwalo, ungqimba lwama-fibre olumazombezombe kufanele lube namandla aphezulu, i-modulus ephezulu, ukuminyana okuphansi, ukuzinza okushisayo kanye nokumanzisa okuhle kwe-resin, kanye nokucutshungulwa okuhle kokusonta kanye nokuqina kwenqwaba ye-fiber efanayo. Amafayibha aqinisayo asetshenziswa kakhulu emikhunjini yokucindezela eyinhlanganisela engasindi ahlanganisaimicu ye-carbonama-PBO fibers,imicu ye-polyamine enephunga elimnandi, kanye nemicu ye-UHMWPE.
