Refractory Material: mefuta e, thepa, kopo
Boitsebiso refractory kamehla entsoeng ka lebaka la thepa ea matsoai tala. Ka tšebeliso thepa ea mohaho kapa liindasteri thepa refractory, 'me le tsona bakeng sa ho sebelisoa nako e telele ka ho sebopehong bona ha ho phetoho. Ho ena "ogneuporku" le atisa ho sebelisoa masimong a sa tšoaneng, ka kholiseho ea hore moralo wa ka tšeptjoang le tsoarellang.
Properties ea thepa refractory
Thepa hlahiswa tse sebelisoang bophelong ba letsatsi le letsatsi libakeng tse ngata. Boitsebiso refractory e sebelisoa ka dithulaganyo tse fapa-fapaneng metallurgical. Sena se ka akarelletsa ho qhibiliha, annealing, ho baka, e le mouoane 'me distillation. Hape u se ke ua lebala hore ho romelwa thepa boloke thepa 'ona sa pele esita le ka kalafo e phahameng mocheso.
Refractories pele sebelisoa ho proizvodnje le hloka boela kalafo, bitsoa crowbar ka. thepa joalo ba atisa ho sebetswa ho bopa sehlahisoa se secha. Ho refractory lintho tse bonahalang e fapaneng ho tloha tse ling tse makgabane matla e phahameng ka thempereichara e phahameng, 'me lik'hemik'hale inertness. Ha e le ba sebopeho, thepa hlahiswa ke metsoako ea ceramic refractory oxide e, metaborate, carbide, nitride le boride.
The tlhophiso ea refractories ka sebopeho le boholo
Boitsebiso refractory ka classified ka dibopeho tsena tse latelang le boholo bo amohela:
- Chesele refractories tloaelehile boholo.
- thepa e tobileng ea rulaganya tse nyenyane le tse khōlō.
- Simple dibopeho.
- Haholo-holo e rarahaneng.
- Krupnoblochnogo thepa eo ba le boima bo boholo ho feta lik'hilograma tse 60.
- Special refractories laboratori ea kapa merero ea liindasteri. Tsena li akarelletsa methapo, crucibles.
Classification tsa refractories eaba ba etsa mokhoa
Re ka khetholla mefuta e ka sehloohong ea thepa refractory ho latela mokhoa oa ho eaba ba etsa:
- chesang tobeletsa thepa.
- Extruded thermoplastic.
- Refractory motsoako sebetswa ho tloha qhibiliha, e leng ba fumanoa ka mokhoa oa ho mocheso motlakase.
- Thepa le mongobo foromo, o ile a fumana ho tswa ho phofo e.
- Refractory polasetiki bōpa, tse entsoeng ka batho ba bangata e khethehileng le boemong polasetiki. Bakeng sa morero ona, e leng mochine o khethehileng bōpa le morago ga moo e dopressovka.
- Lahleloa refractories, tse fumanoa ka ente ea slurry mokelikeli le penoshlikera.
- Pileny refractories lefikeng tlhaho kapa ho na le masakana pele ho ile a etsa.
Hore ba lokela ho sebediswa bakeng sa thepa ea sebōpi?
Bakeng sa kaho ea sebōpi ka sebelisoa thepa vysokoogneupornye ya tshebetso e phahameng. Ka thepa ea bona, ba na le tlaase porosity. Nakong ea theknoloji e etsa thepa sebelisa khethehileng etselitsoeng, kahoo refractory tse bonahalang sebōpi khona ho withstanding maemo phahameng mocheso.
Tsela popontshwa qala ka ba lokisetsa ho ea phofo e le nang itseng phatsa boholo kabo. Joalo buka e ikhethang thepa ea nang le bokhoni ba ho fana ka phokotseho e nyenyane ya bophahamo ba modumo nakong ea tšoarang.
Le melemo le tšimo ea ho sebelisa e sa cheng drywall
Hape u se ke ua lebala ka ho hlahisa itseng thekenoloji mocheso manganga gypsum liboto. Refractory lakane tsa drywall ka sebelisoa bakeng sa tse fapa-fapaneng libakeng liindasteri moo ho na le tšobotsi e hlaheletseng sa tsitsang mongobo le thempereichara e phahameng li ne li tlalehiloe ka tshebetso. lakane thepa Refractory le mefuta gypsum boto cheng ba le palo e kholo ea menyetla:
- Eketseha ditefello tsa mollo.
- Babatsehang utloahalla kwahelang, haholo-holo haeba ho sebelisoa ha drywall ka kopanelo le thepa e 'ngoe ea kaho, ba khethehileng.
- Varaa, boiketlo ea tlhomamiso le boiketlo tsa tšebeliso.
- litekanyo tse nyenyane matlapeng fireproof eo tsamaisane hantle le boholo ba mofuta tekanyetso lakane. Ho makgetheng tsena ho dumella ho kopana le tsona ka kamoreng e tšoanang, haeba ho hlokahala.
- Tshebetso boemo ba bonyane ya acidity.
Tsa mofuta ofe thepa refractory bakeng sa kaho ea marako?
Joalo sehlahisoa sa na le porosity kakaretso ea ba etsang liphesente tse 45 le ka holimo. Ho feta moo, morero oa oona ka sehloohong - e sebediswa e le e kwahelang. Samente ke refractory khabeloa arotsoe unformed, le nang le thepa ea ho thatafatsa ka mor'a ho kopanya le phofo le metsi. Ka ho eketsehileng, batho ba reka mixes feela jwalo.
Sa tsoa hlaha ka 'marakeng oa kaho, le thepa e' ngoe refractory bakeng sa marako, tse kang boima ka konkreiti, lintho tse bonahalang barbotage, Remix ka konkreiti, 'me ba bang ba bangata.
E le thepa refractory li hlahisoa joang?
The ho etsa thepa tshebetso ya thepa fireproof e qala ka ho lokisetsa ka hloko thepa e hlokahalang e tala. Ba sebetsang ka ho etsa thepa ka letsoho kgethile litšila tse sa tšoaneng. Mokhahlelo latelang - le ho sila, sieving, le pheha motsoako. Ho ke ke ho hlokahala hore ba khomarele ho dosing tieo ea likarolo tsohle.
Ntlha bohlokoa ka ho fetisisa nakong ea difeme - sebopeho, omisa, roasting, le khetha. thepa Fireproof lokela tabeng leha e le efe qala ka tlhopho ya e tse bonahalang homolog tala. Lona bonnete ba ho ntlafatsa le ho sila. Ke habohlokoa ho hlokomela hore lintho tse bonahalang e tala e ea mefuta e 'meli - tlhaho le maiketsetso, e leng e khethileng ho ea ka sebeletsana le fono ea lik'hemik'hale le mineralogical sebopeho. hloko ka ho khetheha e leshwa ho sebōpeho sa lihlahisoa tse tala bakeng sa tlhahiso ea e eketsehileng.
Refractory litene bakeng sa kaho ea libaka tsa ho tola
Nakong ea kaho ea motho ka mong o lokela ho hopola hore e tloaelehileng letsopa litene tse khubelu ke ke ba khona ho mamella maemo a batlang e phahameng mocheso. Ba tlang ho qhibiliha 'me qetellong feela raskroshatsya. Ke ka lebaka leo libaka tsohle tse ho feta kapa ka tlaase ho a pepesa hore a mocheso, e lokela ho lined ka litene refractory feela.
A palo e kholo ea batho ba tsebe ka e ikhethang thepa ea thepa refractory hore ka mamella esita le futhumatsang lebetsoeng le. The setene refractory na le yellowish lehlabathe 'mala le lijo-thollo sebopeho. 'Marakeng e fana ka ya khutlonnetsepa le chesele-bopehileng. Ie khetholla soketeng le resaws setene.
Hlahiswa setene behoa feela ka seretse, e leng motsoako oa chamotte le refractory letsopa. seams tsohle, e bopilweng ka ba seretse sa, boetse ho na le ea nang le bokhoni ea withstanding maemo phahameng mocheso (ho fihlela ho likhato 1700 Celsius). Ha nako e ntse, ba ke ke ba felloa le inehella khatello ea.
Classification ea thepa refractory bakeng porosity
lintho tse bonahalang o na le porosity ea lona, e le e mong le e mofuta oa tlhophiso e khethehileng ne a reretsoe:
- segokanyipalo itseng ho akarelletsa ho e porosity bulehileng tsa ho fihlela ho liphesente tse 3.
- Phahameng fokolang ya - ho fihlela ho karolo ea 10 lekholong.
- thepa le letšo-letšo na le porosity bulehileng ea liphesente tse ho fihlela ho 16.
Joale u ka khetha:
