Graphite Carbon Cruciblendi zida zomwe zimagwiritsidwa ntchito kwambiri pakusungunula zitsulo, kugwiritsa ntchito ma labotale, ndi njira zina zamankhwala zotentha kwambiri. Amakhala ndi kukhazikika kwapamwamba kwambiri komanso kutentha kwamafuta, zomwe zimawapangitsa kukhala otchuka kwambiri pamapulogalamuwa. Nkhaniyi ifotokoza momwe mungapangireCarbon Graphite Crucible,kuyambira pakusankhidwa kwa zinthu zopangira mpaka popanga zinthu zomaliza.
Gawo 1: Sankhani zinthu zoyenera za graphite
Chinthu choyamba chopangira graphite crucible ndicho kusankha zinthu zoyenera za graphite. Zojambula za graphite nthawi zambiri zimapangidwa ndi graphite yachilengedwe kapena yopangira. Nazi zina zomwe muyenera kuziganizira posankha zida za graphite:
1. Chiyero:
Kuyera kwa graphite ndikofunikira pakuchita kwa crucible. Ma graphite crucibles apamwamba amatha kugwira ntchito mokhazikika pamatenthedwe okwera ndipo samakhudzidwa mosavuta ndi machitidwe amankhwala. Choncho, kupanga ma graphite crucibles apamwamba nthawi zambiri kumafuna kugwiritsa ntchito zipangizo zoyera kwambiri za graphite.
2. Kapangidwe:
Kapangidwe ka Graphite Lined Crucible ndichinthu chofunikira kwambiri. Ma graphite opangidwa bwino nthawi zambiri amagwiritsidwa ntchito popanga ma crucibles mkati, pomwe ma graphite owoneka bwino amagwiritsidwa ntchito kupanga chipolopolo chakunja. Kapangidwe kameneka kamatha kupereka kukana kofunikira kwa kutentha ndi matenthedwe amtundu wa crucible.
3. Thermal conductivity:
Graphite ndi chinthu chabwino kwambiri chopangira matenthedwe, chomwe ndi chimodzi mwazifukwa zomwe ma graphite crucible amagwiritsidwa ntchito kwambiri pakutentha kwambiri. Kusankha zida za graphite zokhala ndi matenthedwe apamwamba amatha kusintha kutentha ndi kuzizira kwa crucible.
4. Kulimbana ndi dzimbiri:
Kutengera ndi zinthu zomwe zikukonzedwa, nthawi zina zimakhala zofunikira kusankha zida za graphite zokhala ndi dzimbiri. Mwachitsanzo, ma crucibles omwe amanyamula zinthu za acidic kapena zamchere nthawi zambiri amafuna graphite yokhala ndi dzimbiri.
Khwerero 2: Konzani zolemba zoyambirira za graphite
Akasankha chinthu choyenera cha graphite, chotsatira ndicho kukonza zinthu zoyambirira za graphite kukhala mawonekedwe a crucible. Izi nthawi zambiri zimakhala ndi izi:
1. Kuphwanya:
Zinthu zoyambirira za graphite nthawi zambiri zimakhala zazikulu ndipo zimafunika kuphwanyidwa kukhala tinthu tating'onoting'ono tomwe titha kukonza. Izi zitha kutheka kudzera mu kuphwanya makina kapena njira zama mankhwala.
2. Kusakaniza ndi kumanga:
Tinthu tating'onoting'ono ta graphite nthawi zambiri timafunika kusakanikirana ndi zomangira kuti zipange mawonekedwe oyamba a crucible. Zomangira zimatha kukhala utomoni, zomatira, kapena zinthu zina zomwe zimagwiritsidwa ntchito kulumikiza tinthu tating'ono ta graphite kuti chikhale cholimba pamasitepe otsatirawa.
3. Kupondereza:
Ma graphite osakanikirana ndi binder nthawi zambiri amafunika kukanikizidwa mu mawonekedwe a crucible pansi pa kutentha kwakukulu ndi kupanikizika. Izi nthawi zambiri zimamalizidwa pogwiritsa ntchito nkhungu yapadera ya crucible ndi makina osindikizira.
4. Kuyanika:
The crucible crucible nthawi zambiri imafunika kuumitsa kuchotsa chinyezi ndi zosungunulira zina kuchokera ku chomangira. Izi zitha kuchitika pa kutentha pang'ono kuti mupewe kupindika kapena kusweka kwa crucible.
Gawo 3: Sintering ndi processing
Pamene crucible yoyambirira yakonzedwa, njira za sintering ndi chithandizo ziyenera kuchitidwa kuti zitsimikizire kuti crucible ili ndi ntchito yofunikira. Izi nthawi zambiri zimakhala ndi izi:
1. Sintering:
Crucible yoyambirira nthawi zambiri imafunika kuthiridwa pa kutentha kwambiri kuti tinthu tating'ono ta graphite tigwirizane kwambiri ndikuwongolera kachulukidwe ndi mphamvu ya crucible. Izi nthawi zambiri zimachitika pansi pa nayitrogeni kapena mumlengalenga kuti mupewe okosijeni.
2. Chithandizo chapamwamba:
Mawonekedwe amkati ndi akunja a crucibles nthawi zambiri amafuna chithandizo chapadera kuti apititse patsogolo ntchito yawo. Malo amkati angafunike zokutira kapena zokutira kuti ziwonjezeke kukana dzimbiri kapena kuwongolera kutentha. Kunja kungafunike kupukuta kapena kupukuta kuti mupeze malo osalala.
3. Kuyang'anira ndi kuwongolera khalidwe:
Kuyang'anira mozama komanso kuwongolera bwino kuyenera kuchitika panthawi yopanga kuti zitsimikizire kuti crucible ikukwaniritsa zofunikira. Izi zikuphatikizapo kuyang'ana kukula, kachulukidwe, kutentha kwa kutentha, ndi kukana kwa dzimbiri kwa crucible.
Khwerero 4: Kukonza komaliza ndi zinthu zomalizidwa
Pomaliza, crucible yokonzedwa kudzera m'masitepe omwe ali pamwambawa atha kukonzedwa komaliza kuti mupeze chomaliza. Izi zikuphatikiza kudula m'mphepete mwa crucible, kuonetsetsa miyeso yolondola, ndikuwunika komaliza. crucible ikadutsa kuwongolera, imatha kupakidwa ndikugawidwa kwa makasitomala.
Mwachidule, kupanga ma graphite crucibles ndizovuta kwambiri zomwe zimafuna luso lolondola komanso zipangizo zamtengo wapatali za graphite. Posankha zipangizo zoyenera, kukonzekera zipangizo zopangira, sintering ndi processing, ndikugwiritsanso ntchito kuwongolera khalidwe labwino, ma graphite crucibles apamwamba amatha kupangidwa pazinthu zosiyanasiyana zotentha kwambiri. Kupanga ma graphite crucibles ndi gawo lofunikira kwambiri pantchito yopanga uinjiniya wa graphite, kupereka chida chofunikira kwambiri pakugwiritsa ntchito mafakitale ndi sayansi.
