Kuthamangitsa Zaukadaulo Wakuyamika Kwa Graphite kuti mugwire nthawi yayitali ndi kuchita bwino

Zojambulajambula zojambulajambula zomwe zasintha kwambiri ndikubwera kwaukadaulo wokakazira za chiwonongeko, ndikulemba ngati njira yotsogola kwambiri padziko lonse lapansi. Poyerekeza ndi njira zachikhalidwe za mtundu wa mtundu wa mtundu wa mtundu wa mtundu wazovuta zomwe zimapangitsa kuti zigwirizane ndi kapangidwe kake, kachulukidwe ka mphamvu, mphamvu zolimbitsa thupi, komanso kukana kwa oxidation. Kugwiritsa ntchito kukakamizidwa kwambiri pakuumba kwambiri kumapangitsa kapangidwe kake koopsa kapangidwe kake kochititsa chidwi komanso kukana kwa chipongwe, monga momwe zinthu ziliri. Njira iyi, monga tawonetsedwa mu Chithunzi 2, imapangitsa kusintha kwa mavotilo, kumapangitsa kuti pakhale kusintha kwakukulu pakuchita bwino.

1.

Chovuta chomwe chimachitika munthawi ya ng'anjo ya aluminiyamu yolimbana ndi alminit ogwiritsira ntchito zida zojambulajambula, ndi masiku pafupifupi 45. Pambuyo pakugwiritsa ntchito masiku 20 zokha, kuchepa kwa mafuta kumawonedwa, limodzi ndi minyewa yakunja kwapamwamba. Mu magawo a zinthu pambuyo pake, kugwera kwambiri m'matumbo kumaonekera, kumasulira zoopsa pafupifupi zopanda manyazi. Kuphatikiza apo, ming'alu yambiri yakumanja imayamba, ndipo kusataya mtima kumachitika pamwamba pa zopachikidwa chifukwa cha oxidation.

Atayang'ana ng'anjo yovomerezeka, monga tikuonera Chithunzi 3, maziko a njerwa ophatikizika amagwiritsidwa ntchito, ndi chinthu chotenthetsera chapansi chomwe chili pamwamba pa 100 mm pamwamba pa maziko. Pamwamba pa Claccible amasindikizidwa pogwiritsa ntchito mabatani a asbestos, omwe amakhala pafupifupi 50 mm kuchokera kumphepete lakunja, kuwulula kwakukulu abrasion pamphepete mwa nsonga zamkati.

2. Kusintha kwaukadaulo

Kupititsa patsogolo 1: Kukhazikitsidwa kwa ma gray opsinjika graphite yolimba (yokhala ndi oxidation yotsika mtengo)

Kugwiritsa ntchito choopsa kwambiri kumalimbitsa ntchito yake mu aluminiyamu stateconts, makamaka malinga ndi kukana kwa oxidation. Ziphuphu zojambulajambula zimakonda kusinthasintha pa 400 ℃, pomwe kutentha kwa ma aluminium a aluminiyamu kumachitika pakati pa 650 ndi 700 ℃. Zovala zokhala ndi glaze yotsika-kutentha kwambiri zimatha kuchepetsa njira yotsatsira maxidation pa 600 ℃, onetsetsani kuti ali ndi mphamvu yayitali kwambiri. Nthawi yomweyo, imalepheretsa kuchepetsedwa kwa makhilotion, kukulitsa moyo wopachika.

Kupititsa patsogolo 2: Mng'alu wa ntchentche amagwiritsa ntchito graphite za zomwezo monga wopachikidwa

Monga tayikidwira pa Chithunzi 4, pogwiritsa ntchito ziwonetsero za zithunzi zomwezo monga chiwongola dzanja chimatsimikizira kuti pansi paulemerero panjira yotentha. Izi zimachepetsa matenthedwe oyambitsidwa ndi kutentha komanso kumachepetsa chizolowezi cha ming'alu yopanda kutentha pansi. Malo odzipereka odzipereka amatsimikiziranso chithandizo chokhazikika cha choopsa, chogwirizana ndi pansi ndikuchepetsa kuphatikizidwa.

Kupititsa patsogolo 3: Kuchulukiridwa kwa Chovala chakomweko (Chithunzi 4)

1. Kukonzanso m'mphepete mwa ng'anjo yamkati, moyenera kupewa kuvala pamwamba pa ntchentche kwambiri.
2. Kuonetsetsa kuti waya wokakamizidwa ndi mulingo womwe uli ndi woponderezedwa, ndikutsimikizira kuyamikira kokwanira.
3. Kuchepetsa mphamvu ya bulangeti yapamwamba kwambiri pa kuphika, kuwonetsetsa kuti ndi yotentha yolimba kwambiri kumtunda kwa maxidation otsika mtengo.

Kupititsa patsogolo 4: Kukonzanso Njira Zopachika

Musanayambe kugwiritsa ntchito ng'anjoyo pamatenthedwe otsika 200 ℃ kwa maola 1-2 kuti muthetse chinyezi. Pambuyo pa kufalitsa, mwachangu kukweza kutentha kwa 850-900 ℃, kuchepetsa nthawi pakati pa 300-600 ℃ Kuchepetsa makhida pamtunda. Pambuyo pake, tsitsani kutentha ku kutentha komwe kumachitika ndikuyambitsa ma aluminium amadzimadzi ogwirira ntchito.

Chifukwa cha kuwononga zotsatira zoyenga zopatsirana pa zolimba, tsatirani malamulo oyenera ogwiritsira ntchito. Kuchotsa slag nthawi zonse ndikofunikira ndipo kuyenera kuchitidwa pamene wopanduka ndi wotentha, chifukwa kuyeretsa slag kumayambitsa zovuta. Kuwona mawonekedwe owoneka bwino kwa majerecial ndi kukhalapo kwa makoma pa makhoma omwe ali pachimake ndikofunikira mu magawo a pambuyo pake. Kusintha kwa nthawi yake kuyenera kupangidwa kuti apewe kutaya kosafunikira kwa mphamvu zosafunikira ndipo aluminiyumu amadzimadzi.

3. Zotsatira zosintha

Kukhazikika kwamphamvu kwa zopambana ndizofunikira kwambiri, kusamalira kutentha kwa nthawi yayitali, osakhala pansi. Mayankho osuta akuwonetsa ntchito bwino, osati kuchepetsa mtengo wopangira komanso kukulitsa mphamvu yopanga.

4. Kumaliza

1. Chikopa chopanikizika cha ma rafitic chopindika cha zikopa zamitundu yosiyanasiyana malingana ndi magwiridwe antchito.
2. Dongosolo la ng'anjo liyenera kufanana ndi kukula ndi kapangidwe kake kopambana chifukwa cha ntchito yoyenera.
3. Kugwiritsa ntchito koyenera koyenera kwambiri kumatulutsa mtengo wake, moyenera mphamvu zopangira.

Kudzera mu kafukufuku wambiri ndi kukhathamiritsa kwa ntchentche yolimbana ndi magwiridwe antchito ndipo njira yolimbikitsira iperekenitse kwambiri kuti muwonjezere phindu lopanga zinthu ndi ndalama.
