Kugwiritsa Ntchito Mwatsopano kwa Green Silicon Carbide Micropowder mu Makampani Opanga Zoumba
Lao Zhang wakhala akugwira ntchito mu zinthu zadothi kwa zaka zoposa 30. Vuto lake lalikulu linali kuchuluka kwa zokolola. Kusalingana pang'ono pakuwongolera kutentha panthawi yoyatsa uvuni kungayambitse ming'alu ndi kusintha kwa zinthuzo. M'zaka zaposachedwa, fakitale yake yayamba kugwiritsa ntchito zinthu zotchedwa "ufa wa micropowder wobiriwira wa silicon carbider,” ndipo zinthu zasintha kwambiri. “Ndi zodabwitsa kwambiri,” iye akutero. “Zili ngati kuwonjezera MSG pa chakudya—zimawonjezera kukoma ndi kusunga kusinthasintha.”
Ufa wobiriwira wa silicon carbide ndi ufa wobiriwira wosalala kwambiri wokhala ndi kuuma kwambiri, kukana kutentha kwambiri, komanso mphamvu zokhazikika za mankhwala. Poyamba unkagwiritsidwa ntchito makamaka popangira zinthu zopukutira, zopinga kutentha, komanso zodula zinthu za semiconductor, palibe amene ankayembekezera kuti udzabwereranso m'makampani opanga zinthu zadothi. Komabe, wayambitsa njira zatsopano zambiri m'makampani opanga zinthu zadothi m'zaka zaposachedwa.
1. N’chifukwa chiyani sindinaganizirepo izi kale? — “Chinthu chachikulu” chosintha ufa wa micropowder
Zinthu zadothi zingawoneke ngati zosavuta, koma kwenikweni zimakhala zovuta kwambiri. Zinthu zadothi zachikhalidwe zimakhala ndi vuto lochepa kwambiri zikauma komanso zikamasungunuka, zomwe zimapangitsa kuti zisweke. Magalasi nthawi zambiri amasweka chifukwa cha kuchuluka kwa kutentha komwe sikukugwirizana. Kusiyana kwakukulu komwe kumachitika chifukwa cha kuwonjezera ufa wobiriwira wa silicon carbide ndi kukhazikika bwino.
Chifukwa cha kuuma kwake kwakukulu komanso kukula kwa tinthu tating'onoting'ono, kulowa kwake m'thupi kumadzaza malo opanda kanthu ndikupanga kapangidwe kolimba. Monga mwa mawu a katswiri wodziwa bwino ntchito, "Zili ngati kukanda mtanda kwa mphindi khumi—zimapangitsa kuti ukhale wotafuna kwambiri." Komanso,kabide wobiriwira wa silikoni Kutenthetsa kwabwino kwa ufa wa micropowder kumatsimikizira kufalikira kwa kutentha kofanana mu uvuni, kuchepetsa chiopsezo cha kutentha kwambiri komwe kumachitika m'deralo kapena kutenthedwa pang'ono. Zili ngati kutenthetsa buns mu chitofu choyaka ndi nkhuni, chomwe kale chinali chovuta kulamulira. Tsopano, ma steamer amakono amapereka njira yosavuta komanso yothandiza.
2. Si chinthu chongowonjezera mphamvu chabe, komanso ndi chinthu cholimbikitsa anthu.
Komabe, kuganizira kuti ufa wobiriwira wa silicon carbide ndi "cholimbitsa" kungakhale kunyoza kwambiri. Mafakitale a ceramic a masiku ano samangokhala opanga mbale, mabeseni, ndi miphika yokha. Zinthu zapamwamba monga ceramics zomangidwa, ceramics zamagetsi, ndi ceramics zosatha kutha zikukhala zotchuka kwambiri, ndipo ufa wobiriwira wa silicon carbide wachitadi gawo la "katswiri wodutsa malire."
Mwachitsanzo, zinthu zamagetsi zogwiritsa ntchito ceramic zimafuna kutentha kwambiri, kutenthetsa kwambiri, komanso kukulitsa pang'ono; ngakhale kusiyana pang'ono kungakhudze moyo wa zinthuzo. Kuwonjezera kuchuluka koyenera kwa ufa wobiriwira wa silicon carbide micropowder kumathandizira kwambiri osati mphamvu ya makina yokha komanso kutentha. "Zili ngati kuyika jekete loziziritsa mpweya pa bolodi lamagetsi," injiniya wina anafotokoza.
Chitsanzo china ndi zoumba zadothi zosatha. Zoumba zadothi zimagwiritsidwa ntchito kwambiri m'makina opangira migodi ndi zida zopangira magetsi. Kale, zoumba zadothi za alumina zinkatha msanga ndipo zinkafunika kusinthidwa pafupipafupi. Kuwonjezera ufa wobiriwira wa silicon carbide kunawonjezera kwambiri kuuma ndi kukana kwa zoumba zadothi, zomwe zinawonjezera nthawi yawo yogwira ntchito ndi zoposa 30%.
3. Kusiyana pakati pa "kukonda dziko lapansi" ndi "ukadaulo" ndi ufa wochepa chabe
Zingakhale zovuta kuganiza kuti zinthu zoumbaumba, zomwe kale zinkaonedwa ngati makampani achikhalidwe a "matope ndi moto," tsopano zikugwiritsa ntchito ukadaulo wapamwamba pang'onopang'ono. Ufa wobiriwira wa silicon carbide ndi chimodzi mwa zinthu zofunika kwambiri zomwe zasintha zinthu zoumbaumba kuchokera ku "zachikhalidwe" kupita ku "zamakono."
Mwachitsanzo, makampani ena pakali pano akuyesa kusindikiza kwa 3D kuti apange zigawo zovuta za ceramic. Njirazi nthawi zambiri zimalephera chifukwa cha kuchepa kwakukulu panthawi yosindikiza. Kuwonjezera ufa wobiriwira wa silicon carbide ku ceramic slurry kumawongolera kwambiri kupangika ndi kukhazikika kwa zigawo zosindikizidwa, zomwe zimathandiza kuti ngakhale zigawo zazing'ono za ceramic zisindikizidwe bwino nthawi imodzi.
Chitsanzo china ndi zinthu zosefera za ceramic zomwe siziwononga chilengedwe. Pokonza madzi otayira kapena mpweya wotulutsa utsi m'mafakitale, zosefera za ceramic zachikhalidwe zimatha kutsekeka komanso kusowa mphamvu. Kuwonjezeredwa kwa ufa wobiriwira wa silicon carbide kumapangitsa kuti zinthu zosefera zikhale ndi ma pores ofanana, mawonekedwe abwino a makina, komanso kukana mankhwala, zomwe zimapangitsa kuti zikhale "zolimba komanso zolimba."
4. Ngakhale kuti pali zovuta, njira yomwe ikupita patsogolo ikupita patsogolo.
Pameneufa wobiriwira wa silicon carbide micropowderndi chiyembekezo, si mankhwala othetsera mavuto. Vuto lalikulu pakadali pano ndi mtengo. Ufa wobiriwira wa silicon carbide woyera kwambiri ukadali wokwera mtengo, zomwe zimapangitsa kuti kugwiritsa ntchito kwambiri zinthu zadothi zapakatikati ndi zotsika mtengo kukhale kovuta kwa makampani opanga zinthu zadothi zapakatikati ndi zotsika mtengo.
Vuto lachiwiri ndi kusinthasintha kwa njira. Ma ceramic formulations osiyanasiyana ndi makina oyaka amafunika zofunikira zenizeni za kukula kwa tinthu tating'onoting'ono ndi mlingo wa ufa wa micropowders. Kupambana sikungapezeke mwa kungo "kungotaya." Kumafuna kuyesa ndi kulakwitsa kwakukulu, komanso kumafuna kusintha kwa mizere yopangira yomwe ilipo. "Muyenera kuwoloka mtsinje pogwira miyala, koma mukangoyikonza bwino, msewu umakhala wokulirapo," adatero manejala wopanga.
Komabe, makampani ambiri akufunitsitsa kuyika ndalama mu kafukufuku ndi chitukuko, ndipo ufa wobiriwira wa silicon carbide wopangidwa mdziko muno wayambitsidwa. Mitengo ikukwera mtengo kwambiri, ndipo ukadaulo wogwiritsa ntchito ukukwera.
5. Mapeto: Ufa Waung'ono, Tsogolo Lalikulu
Poganizira m'mbuyo, kugwiritsa ntchito ufa wobiriwira wa silicon carbide mumakampani opanga zinthu zadothi ndi chitsanzo chabwino kwambiri cha "kusintha kwa zinthu zomwe zimapangitsa kuti mafakitale asinthe." M'malo mopanganso gudumu, kumakonza ndikuphatikiza njira zomwe zilipo kale, ndikupangitsa moyo watsopano kukhala waluso wachikhalidwe.
Monga momwe katswiri wina wa mafakitale ananenera, "Zopangira zinthu zadothi zasintha ndipo sizinasinthe kwa zaka masauzande ambiri. Dongo likadali lomwelo, moto ukadali womwewo, koma kuwonjezera china chatsopano kumapanga mwayi watsopano."
Mwina kupanga zinthu zatsopano kuli motere: sikuyenera kukhala kosokoneza dziko lapansi, kumangofunika kukhala koyenera. Ufa wobiriwira wa silicon carbide ndi chinthu ichi—mosazindikira komanso mwakachetechete chikusintha chilengedwe ndi tsogolo la zinthu zadothi.
Zinthu za m'tsogolo zitha kukhala zopepuka, zolimba, komanso zanzeru kwambiri. Ndipo “anthu olimba mtima osaoneka” monga ufa wobiriwira wa silicon carbide angatibweretsere zodabwitsa zambiri.
