Ucwaningo kanye Nokuthuthukiswa Metal Foam
Ukuthuthukiswa kwezinto ezintsha kuyisihluthulelo sokuqanjwa kabusha kwezobuchwepheshe enkathini entsha, okuhlinzeka ngendlela entsha yokuvikela imvelo nokonga amandla, futhi kuhlobene eduze nomnotho wezwe kanye nesimanje. Izinto zensimbi ezinegwebu azigcini nje ngokuba nezici zesisindo esilula izinto ezivamile ezinama-porous, kodwa futhi zinezakhiwo ezinhle kakhulu zemishini kanye nezakhiwo ezibonakalayo ezifana nokushisa nogesi, futhi kulula ukuvuselela kunamagwebu e-polymeric, ukwandisa uhla lwesicelo sezinto ezinama-porous. Eminyakeni yamuva, ukuthuthukiswa kobuchwepheshe obusha kuye kwathuthukisa kakhulu izinga lensimbi enegwebu, futhi izimo zokusetshenziswa kwezinto ezintsha nazo zishintshile kakhulu. Abantu sebeqala ukuba nesithakazelo ekuthuthukisweni kwensimbi enegwebu, ikakhulukazi ingxubevange ye-aluminium enegwebu. Isibonelo: embonini yezimoto, ngenxa yesidingo esikhulayo sokuphepha nokuvikelwa kwemvelo, abantu baqala ukucabangela ukusetshenziswa kwensimbi ye-foam.
1. Inqubo yokulungiselela kanye nokuthuthukiswa kwe-foam yensimbi
Inqubo yokulungiselela amagwebu ensimbi iphefumulelwe ukulungiswa kwamagwebu e-polymeric futhi iye yathuthukiswa ngokuqhubekayo ngenxa yezakhiwo zayo zensimbi eziyingqayizivele. Amagwebu ensimbi angahlukaniswa abe izinhlobo ezimbili: nge-cell kanye ne-closed-cell ngokusho kwesakhiwo sawo sangaphakathi se-pore. Izindlela zokulungiselela zingafingqwa ngale ndlela elandelayo:
I-Metal Foam ihlukaniswe yaba:
- Igwebu lensimbi elivaliwe lihlukaniswe ngendlela yokuncibilika kwegwebu, indlela yokwenza impushana, yengeza indlela yebhola engenalutho, nendlela yokufafaza.
- Insimbi yegwebu nge-hole ihlukaniswe yaba indlela yokukhipha amanzi, indlela yokutshala imali, indlela ye-sintering kanye nendlela yokucwenga kwensimbi.
2. Izakhiwo zensimbi ye-foam
Amagwebu ensimbi abonisa izinto ezithakazelisayo ngenxa yesakhiwo sazo esinezimbotshana, ehlanganisa izakhiwo zensimbi eyisisekelo kanye nesakhiwo sayo.
Njengempahla yesakhiwo, izakhiwo zemishini ye-foam yensimbi ikakhulukazi zincike ekumineni kwayo kanye nezakhiwo zensimbi eyisisekelo. Isibonelo, igwebu lensimbi elinokuminyana okuphezulu libuye libe namandla aphezulu okucindezela, futhi igwebu lensimbi elinamandla amakhulu e-matrix nalo linamandla okucindezela aphezulu.
Njengento esebenzayo, inezinto ezibonakalayo ezahlukahlukene njengokumuncwa komsindo, ukuhlunga, ukwahlukanisa ukushisa, i-flame retardant, ukunciphisa ukudlidliza, ukumanzisa, ukumunca amandla okunomthelela, nokuvikela i-electromagnetic.
Phakathi kwazo, okufundwa kakhulu futhi okusetshenziselwa kabanzi ukumuncwa kwamandla kwegwebu lensimbi.
3. Ukusetshenziswa kwensimbi yegwebu
Ukusetshenziswa kuncike ekusebenzeni, futhi ukusebenza okuhle kakhulu kwensimbi ye-foam kunquma ububanzi bayo bokusetshenziswa.
Njengamanje, ezinye izakhiwo ze-foam metal ziye zasetshenziswa eJapane. Isibonelo, izakhiwo ezimunca umsindo zegwebu le-aluminium zisetshenziswa emakamelweni aphehla amandla ezitimeleni zaseHokkaido namathuluzi okunciphisa umsindo emafektri, izihlalo zesitimela ze-JR Shinkansen zisebenzisa uhlaka oluyinhlanganisela lwegwebu le-aluminium, kanye nezakhiwo zokuhlobisa eziyingqayizivele i-foam surface nayo isetshenziswa ezakhiweni. Imboni.
Amagwebu ensimbi nge-pore asetshenziswa njengezinto zokuhlunga, izishintshi zokushisa, izihlungi nezisekelo ze-catalyst, futhi zisetshenziswa njengezinto ze-electrode.
