'Wankhondo Wa diamondi' mu Mapaipi A mafakitale: Chifukwa Chiyani Silicon Carbide Pipeline Imaonekera?

M'mafakitale a mankhwala, mphamvu, ndi kuteteza chilengedwe, mapaipi ali ngati "mitsempha ya magazi" ya zida, zomwe zimanyamula zoulutsira nkhani zosiyanasiyana. Koma zinthu zina zogwirira ntchito zimatha kutchedwa "purigatoriyo": malo otentha kwambiri amatha kupanga zitsulo zofewa, ma acid amphamvu ndi alkalis amatha kuwononga makoma a mapaipi, ndipo madzi omwe ali ndi tinthu tating'onoting'ono adzapitirira kuphwa ndi kutha. Panthawi imeneyi, mapaipi achikhalidwe nthawi zambiri amavutika, pomwemapaipi a silicon carbideakuthetsa mavutowa ndi chikhalidwe chawo chosasweka.
Wobadwa Wamphamvu: Mawu achinsinsi a Silicon Carbide
Mphamvu ya silicon carbide ceramics ili mu "majini" ake - zoumba za silicon carbide zimadziwika kuti "diamondi yakuda" yamafakitale, ndi zabwino zitatu zazikuluzikulu.
Kulimba kwake n’kosayerekezereka, chachiŵiri kwa diamondi ndi kuŵirikiza kasanu kuposa chitsulo wamba. Poyang'anizana ndi kukokoloka kwa madzi okhala ndi tinthu tolimba, kuli ngati kuvala "zida zankhondo zosamva kuvala" zomwe sizimavala mosavuta komanso zimakhala ndi moyo wautali wautumiki kuposa mapaipi achitsulo. M'malo otentha kwambiri, ndi 'calm master', ngakhale kutentha kwa masauzande a madigiri Celsius, kapangidwe kake kamakhala kokhazikika, mosiyana ndi chitsulo chosapanga dzimbiri chomwe chimatsika mwadzidzidzi mphamvu pa kutentha pang'ono. Ndipo imatha kupirira kusintha kwakukulu kwa kutentha, ndipo sichitha kusweka ngakhale mwadzidzidzi kuwululidwa ndi ma TV otentha kwambiri m'nyengo yozizira.
Chofunikira kwambiri ndi "talente yolimbana ndi dzimbiri", yomwe imatha kutchedwa acid-base "immune". Kaya ndi ma asidi amphamvu monga sulfuric acid ndi hydrofluoric acid, kuchuluka kwa sodium hydroxide ndi maziko amphamvu, kapena ngakhale kupopera mchere ndi zitsulo zosungunuka, zimakhala zovuta kuwononga khoma lake la chitoliro. Izi zimathetsa vuto lalikulu la kuwonongeka kwa mapaipi ndi kutayikira m'mafakitale ambiri.
Poyerekeza ndi miyambo: chifukwa chiyani ndi yodalirika?
Poyerekeza ndi mapaipi achikhalidwe, ubwino wa mapaipi a silicon carbide ukhoza kunenedwa kuti ndi "kunyanyala kuchepetsa milingo".
Mapaipi achitsulo amatha kufewetsa pakatentha kwambiri ndipo amatha kuwonongeka ndi electrochemical corrosion akakumana ndi asidi ndi alkali. Zonyansa zimatha kuchulukiranso panthawi yonyamula zida zolondola, zomwe zimakhudza mtundu wawo. Ngakhale mapaipi apulasitiki a uinjiniya ndi osagwirizana ndi dzimbiri, malire awo okana kutentha ndi otsika kwambiri, nthawi zambiri amakhala osakwana 200 ℃, komanso amakonda kukalamba komanso kusweka. Mapaipi wamba a ceramic sagonjetsedwa ndi kutentha kwakukulu komanso kutha, koma ndi olimba kwambiri ndipo amatha kusweka ngakhale kusinthasintha pang'ono kwa kutentha.

Ndipo mapaipi a silicon carbide amapewa bwino zofooka izi, ndi mphamvu zazikulu zitatu za kuuma, kukana kutentha, ndi kukana kwa dzimbiri zomwe zimagwiritsidwa ntchito mokwanira, zomwe zimakwaniritsa bwino zofunikira zamakampani amakono kuti "akhale ndi moyo wautali, bata, ndi kukonza pang'ono" mapaipi.
Kulowa m'makampani: Kukhalapo kwake kumapezeka paliponse
Masiku ano, mapaipi a silicon carbide akhala "muyezo" pazinthu zambiri zogwirira ntchito. M'makampani opanga mankhwala, ndiye kuti ali ndi udindo wonyamula ma acid ndi ma alkali osiyanasiyana popanda kusintha ndi kukonza pafupipafupi; Mu dongosolo la desulfurization ndi denitrification la zomera zamagetsi, zimatha kupirira kutentha kwakukulu ndi malo owononga kwambiri, ndipo moyo wake wautumiki ukhoza kupitirira zaka 10.
M'mafakitale a semiconductor, kuyeretsedwa kwake kopitilira muyeso kumatsimikizira kuipitsidwa kwa zero pakunyamula mpweya woyeretsedwa kwambiri, ndikupangitsa kukhala "golide" wopangira chip; M'makampani opanga zitsulo, amatha kunyamula tinthu tating'onoting'ono totentha kwambiri ndi ufa wa ore popanda kuopa kukokoloka ndi kuvala. Ngakhale m'makampani opanga ndege, ma ducts okwera kwambiri a gasi a injini za rocket sangathe kuchita popanda thandizo lawo.
Pakupambana kwaukadaulo wapakhomo, mtengo wamapaipi a silicon carbide watsika kwambiri, ndipo amathanso kusinthidwa kuti agwirizane ndi minda yomwe ikubwera monga mphamvu ya haidrojeni ndi zakuthambo kudzera munjira zamakina makonda. Uyu' Diamond Warrior 'm'mapaipi a mafakitale akugwiritsa ntchito mphamvu zake kuteteza magwiridwe antchito a mafakitale osiyanasiyana.
