Lisebelisoa tse tloaelehileng tsa tšimo ea mocheso: Lisebelisoa tsa motsoako oa C / C

Lisebelisoa tsa carbon-carbonKe mofuta oa li-composites tsa carbon fiber, tse nang le carbon fiber e le thepa e matlafatsang 'me e behiloe carbon e le thepa ea matrix. Matrix eaLi-composite tsa C / C ke carbon. Kaha e batla e entsoe ka elemental carbon, e na le ho hanyetsa mocheso o phahameng haholo 'me e rua thepa e matla ea mochine oa carbon fiber. E 'nile ea etsoa indasteri lefapheng la ts'ireletso pejana.

Libaka tsa kopo:
Lisebelisoa tse kopantsoeng tsa C / Cli fumaneha bohareng ba ketane ea indasteri, 'me ho ea holimo ho kenyelletsa carbon fiber le tlhahiso ea preform,' me masimo a kopo a tlase a batla a pharaletse.Lisebelisoa tse kopantsoeng tsa C / Cli sebelisoa haholo-holo e le lisebelisoa tse thibelang mocheso, lisebelisoa tsa ho hohla, le lisebelisoa tse phahameng tsa ts'ebetso. Li sebelisoa sebakeng sa sefofane (li-rocket nozzle linings tsa 'metso, lisebelisoa tsa ts'ireletso ea mocheso le likarolo tsa enjene ea mocheso), lisebelisoa tsa mariki (seporo se lebelo le holimo, li-brake discs tsa sefofane), libaka tsa mocheso oa photovoltaic (libarele tsa insulation, li-crucibles, li-tubes tse tataisang le likarolo tse ling). mmele wa baeloji (masapo a maiketsetso) le mafapha a mang. Hona joale, malapengLisebelisoa tse kopantsoeng tsa C / Clik'hamphani li shebana haholo le sehokelo se le seng sa lisebelisoa tse kopaneng 'me li atoloha ho ea pele ho tataiso e holimo.

Lisebelisoa tsa motsoako oa C / C li na le ts'ebetso e ntle haholo, e nang le boima bo tlaase, matla a phahameng a khethehileng, modulus e phahameng e phahameng, mocheso o phahameng oa mocheso, mocheso o tlaase oa ho eketsa mocheso, ho thatafala ha fracture, ho hanyetsa ho roala, ho hanyetsa ablation, joalo-joalo, ho fapana le lisebelisoa tse ling. matla a lisebelisoa tsa motsoako oa C / C a ke ke a fokotseha empa a ka eketseha ka ho eketseha ha mocheso. Ke thepa e sa cheng mochesong, ka hona e qalile ho etsoa indastering ea li-rocket throat.

Lintho tse entsoeng ka C / C li rua thepa e babatsehang ea mechine le thepa ea ho sebetsa ea carbon fiber, 'me e na le ho hanyetsa mocheso le ho hanyetsa ho bola ha graphite,' me e fetohile mohatelli ea matla oa lihlahisoa tsa graphite. Haholo-holo tšimong ea kopo e nang le litlhoko tse phahameng tsa matla - sebaka sa mocheso oa photovoltaic, ts'ebetso ea litšenyehelo le ts'ireletseho ea lisebelisoa tse kopantsoeng tsa C / C li ntse li hlahella le ho feta tlas'a liphaphatha tse kholo tsa silicon, 'me e fetohile tlhokahalo e thata. Ho fapana le hoo, graphite e fetohile tlatsetso ho lisebelisoa tse kopantsoeng tsa C / C ka lebaka la bokhoni bo fokolang ba tlhahiso ka lehlakoreng la phepelo.

Tšebeliso ea sebaka sa mocheso oa Photovoltaic:
Sebaka sa mocheso ke tsamaiso eohle ea ho boloka khōlo ea silicon ea monocrystalline kapa tlhahiso ea li-ingots tsa polycrystalline silicon mocheso o itseng. E bapala karolo ea bohlokoa ho hloekeng, ho ts'oana le litšoaneleho tse ling tsa silicon ea monocrystalline le silicon ea polycrystalline, 'me ke ea karolo e ka pele ea indasteri ea tlhahiso ea silicon. Sebaka sa mocheso se ka aroloa ka mokhoa oa mocheso oa mocheso oa sebōpi sa monocrystalline silicon se nang le kristale e le 'ngoe le tsamaiso ea mocheso oa mocheso oa polycrystalline ingot sebōpi ho latela mofuta oa sehlahisoa. Kaha lisele tsa silicon tsa monocrystalline li na le ts'ebetso e phahameng ea phetoho ho feta lisele tsa silicon tsa polycrystalline, karolo ea 'maraka ea li-wafers tsa silicon e ntse e eketseha, ha karolo ea mmaraka ea li-wafers tsa polycrystalline naheng ea heso e ntse e fokotseha selemo le selemo, ho tloha ho 32.5% ka 2019 ho isa ho 9.3% ka 2020. Ka hona, baetsi ba masimo a mocheso haholo-holo ba sebelisa tsela ea theknoloji ea tšimo ea mocheso ea ho hula ka kristale e le 'ngoe. libopi.

Setšoantšo sa 2: Tšimo ea mocheso ka har'a ketane ea indasteri ea tlhahiso ea silicon

Sebaka sa mocheso se entsoe ka likarolo tse fetang leshome le metso e 'meli, 'me likarolo tse' nè tsa mantlha ke crucible, tube guide, insulation cylinder, le heater. Likarolo tse fapaneng li na le litlhoko tse fapaneng tsa thepa ea thepa. Setšoantšo se ka tlase ke setšoantšo sa moralo oa tšimo ea mocheso oa silicon e le 'ngoe ea kristale. The crucible, tube guide, le cylinder ea ho kenya letsoho ke likarolo tsa sebopeho sa tsamaiso ea tšimo ea mocheso. Mosebetsi oa bona oa mantlha ke ho ts'ehetsa sebaka sohle sa mocheso o phahameng oa mocheso, 'me ba na le litlhoko tse phahameng tsa ho teteana, matla le ho tsamaisa mocheso. Mofuthu ke ntho e futhumatsang ka ho toba tšimong ea mocheso. Mosebetsi oa eona ke ho fana ka matla a mocheso. Ka kakaretso e hanyetsa, kahoo e na le litlhoko tse phahameng tsa ho hanyetsa lintho tse bonahalang.
