Ha re khetha sehlahisoa sa fiber ea ceramic, ka sebele re tla botsa moetsi bakeng sa lintlha tse ka sehloohong tsa ts'ebetso ea sehlahisoa le ho utloisisa boleng ba data bakeng sa ho buuoa ha ho khethoa, empa mohlomong moreki ha a hlake hantle ka moelelo oa boleng kapa ntho e ncha. bareki ha ba utloisise se boleloang ke data, kamehla re buisane le rona mabapi le moelelo oa data.Kajeno 100 hlahloba hore u hlalose lihlahisoa tsa ceramic fiber tsa tsebo ena e nyenyane, ke tšepa ho u thusa!
1 Phapang pakeng tsa lisebelisoa tsa ho kenya mocheso le lisebelisoa tsa refractory
Ka kakaretso, ka tlase ho 1570 ℃ e bitsoa thepa ea ho kenya letsoho;Ka holimo ho 1570 ℃ ke lisebelisoa tse refractory.Lisebelisoa tsa khale tsa refractory hangata li bua ka litene tse boima tsa mollo, tse ka lahloang, joalo-joalo, boima ba molumo hangata ke 1000-2000kg/m3.
Melemo ea fiber ea ceramic e totobetse haholo, tlas'a motheo oa ts'ebetso e babatsehang ea ho kenya mocheso oa mocheso, empa hape e na le ho hanyetsa mollo o motle, 'me ke ea thepa e khanyang, ho fokotsa mojaro oa sebōpi, ho fokotsa haholo ho kenngoa ha setso ka lebaka la tšehetso ea boima bo boima. lisebelisoa tse jeoang ke palo e kholo ea tšepe.
2 terata e chesang e honyela
Index bakeng sa ho hlahloba ho hanyetsa mocheso (mocheso oa tšebeletso) oa lihlahisoa tsa fiber ea ceramic.Litlhokahalo tsa machaba tse kopaneng tsa lihlahisoa tsa fiber ea ceramic tlas'a ho futhumatsa ho se nang mojaro ho mocheso o itseng, ho boloka mocheso bakeng sa lihora tse 24 tsa mocheso o phahameng oa mohala oa shrinkage o bonts'a ho hanyetsa mocheso oa fiber ea ceramic.
Mocheso oa mocheso oa mocheso oa mocheso oa ho fokotseha ha terata ≤3% ke mocheso o tsoelang pele oa tšebeletso oa lihlahisoa tsa fiber ea ceramic.Ka mocheso ona, likhoele tsa amorphous ceramic fibers li phatsima 'me li hola butle,' me thepa ea fiber e tsitsitse ebile e otlolohile.
Mocheso oa ho fokotseha ha terata e futhumatsang ≤4% mocheso oa teko bakeng sa lihlahisoa tsa fiber ea ceramic li sebelisa mocheso.
3 Thermal conductivity
Thermal conductivity ke mofuta oa thepa ea 'mele ea thepa, e leng index ea thepa ea ho kenya mocheso ea fiber ea ceramic.
E itšetlehile ka sebopeho sa lihlahisoa tsa fiber ea ceramic, boima ba molumo, mocheso, sepakapaka sa sebōpi, mongobo le lintlha tse ling.
Ceramic fiber ke motsoako oa fiber e tiileng le moea o nang le porosity ea 93%.Moea o mongata o nang le conductivity e tlaase ea mocheso o tletse li-pores, 'me mohaho o tsoelang pele oa marang-rang oa limolek'hule tse tiileng oa senyeha, e le ho fumana ts'ebetso e babatsehang ea adiabatic.'Me ha bophara ba pore bo nyane, haufi le tataiso ea phallo ea mocheso ka fiber e tiileng e arotsoe ka boemo bo koetsoeng ba palo ea li-pores, ho ntlafatsa ts'ebetso ea mocheso oa mocheso oa fiber ea ceramic.
4. Tšusumetso ea metsoako ea lik'hemik'hale
Sebopeho sa lik'hemik'hale se khetholla ka kotloloho ho hanyetsa mocheso oa fiber:
(1) Al2O3, SiO2, ZrO2, Cr2O3 le likarolo tse ling tse sebetsang hantle ≥99%, mocheso o phahameng oa oxide content, o khetholla ka ho toba tshebetso ea fiber ea ceramic.
(2) Fe2O3, Na2O, K2O, MgO le litšila tse ling tse ka tlaase ho 1%, ke tsa litšila tse kotsi, ka ho toba li lebisa ho senyeha ha ts'ebetso ea fiber ea ceramic.
