Li-tubes tse khanyang tsa silicon carbide
Li-tubes tse khanyang tsa silicon carbideke likarolo tse tsoetseng pele tsa ceramic tse tsebahalang haholo bakeng sa ts'ebetso ea tsona e ikhethang lits'ebetsong tsa indasteri tse chesang haholo le tse senyang. Thepa ea bona e ikhethang ea thepa le ho feto-fetoha ha maemo ho etsa hore e be tsa bohlokoa haholo maemong a thata a ts'ebetso. Ka tlase ke kakaretso ea melemo le lits'ebetso tsa bona tsa bohlokoa.
1. Lintho tse Phahameng ka ho Fetisisa
SiC ke lisebelisoa tsa ceramic tse sebetsang hantle tse nang le litšobotsi tse ikhethang:
(1) Ho hanyetsa Mocheso o Feteletseng: Ho khona ho sebetsa ka mokhoa o tsoelang pele ho mocheso ho fihlela ho 1600 ° C le ho pepeseha ha nako e khutšoanyane ho feta 1800 ° C, ho feta hole litharollo tsa setso tse thehiloeng ka tšepe.
(2) High Thermal Conductivity: Ka conductivity ea mocheso ka makhetlo a 2-3 ho feta tšepe, li-tubes tse khanyang tsa Silicon carbide li nolofalletsa ho futhumala ka potlako le ho fana ka mocheso o tšoanang.
(3) Ho Atolosoa ha Mocheso o Motle: Katoloso ea bona e fokolang ea mocheso e fokotsa khatello ea maikutlo nakong ea ho fetoha ha mocheso, ho netefatsa botsitso ba sebopeho.
(4) Resistance ea Corrosion le Oxidation: E hanana le li-acids, alkalis, tšepe e qhibilihisitsoeng, le likhase tse mabifi, le tlas'a maemo a nako e telele a mocheso o phahameng.
2.Tlhahiso ea Sebopeho
Li-tubes tse khanyang tsa Silicon carbide li ka etsoa ho latela litlhoko tse fapaneng tsa indasteri:
(1) Meetso e ka tloahelehang: E fumaneha ka sebopeho se otlolohileng, sa U, kapa sa W ho ntlafatsa kabo ea mocheso le tšebeliso ea sebaka.
(2) Khokahano e Matla: E lumellana le li-flanges tsa tšepe kapa lisebelisoa tsa ho tiisa ka ceramic bakeng sa likhokahano tse sa lutlang ho li-setups tse rarahaneng.
- Melemo ea Ts'ebetso
(1) Matla a Matla: Ts'ebetso e phahameng ea mocheso e fokotsa tšebeliso ea matla ka ho etsa hore mocheso o fete kapele.
(2) Bophelo bo Bolelele ba Tšebeletso: Li-tubes tse khanyang tsa silicon carbide hangata li nka nako e telele ea 3-5 ho feta mekhoa e meng ea tšepe libakeng tse thata, ho fokotsa nako ea ho theoha le litšenyehelo tsa ho fetola.
(3) Thermal Shock Resistance: E mamella potoloho e potlakileng ea ho futhumatsa le ho pholisa ntle le ho phatloha, e loketseng lits'ebetso tse hlokang hore mocheso o fetohe khafetsa.
4. Lisebelisoa tsa Bohlokoa tsa Indasteri
Li-tubes tse khanyang tsa silicon carbide li sebetsa hantle haholo makaleng a bohlokoa:
(1) Metallurgy: E sebelisoa ka har'a libopi tsa mollo, libopi tsa carburizing, le lits'ebetso tsa brazing bakeng sa kalafo e tšoanang ea mocheso.
(2) Ts'ebetso ea Lik'hemik'hale: Sebeletsa e le li-tubes tsa reaction kapa li-catalyst supports ho li-reactors tsa mocheso o phahameng le libopi tsa pyrolysis.
(3) Tlhahiso ea Ceramics / Glass: Netefatsa taolo e nepahetseng ea mocheso ka har'a libopi tsa sintering le libopi tse qhibilihang ka likhalase.
(4) Litsamaiso tsa Tikoloho: E kentsoe ka har'a licheso tsa litšila le likarolo tsa kalafo ea mosi ho sebetsana le likhase tse senyang mochesong o phahameng.
5. Melemo e Bapisang ho Feta Mekhoa e meng:
| Thepa | Li-tubes tse khanyang tsa silicon carbide | Metal Tubes | Li-tubes tsa Quartz |
| Mocheso o Moholo | 1600 ℃ | ＜1200℃ | ＜1200℃ (nako e khutšoane) |
| Khanyetso ea Corrosion | E kgabane | E itekanetseng | E futsanehile libakeng tsa alkaline |
| Thermal Shock Resistance | Phahameng | Tlase | E itekanetseng |
6. Hobaneng u Khetha li-tubes tse khanyang tsa Silicon carbide?
Silicon carbide radiant tubes ke khetho e nepahetseng bakeng sa liindasteri tse tlang pele:
(1) Ho tsitsisa ho feteletseng ha mocheso ntle le ho senyeha ha tshebetso.
(2) Ho ts'epahala ha nako e telele libakeng tse senyang kapa tse nang le oxidizing.
(3) Ho futhumatsa ka mokhoa o sebetsang hantle le o ts'oanang bakeng sa lits'ebetso tse tsamaisoang ka nepo.
Shandong Zhongpeng Special Ceramics Co., Ltd ke e 'ngoe ea litharollo tse ncha tsa silicon carbide ceramic China. SiC tekheniki ea ceramic: Ho thatafala ha Moh ke 9 (Bothata ba Moh e Ncha ke 13), e nang le khanyetso e babatsehang ea khoholeho ea mobu le ho bola, ho senya ho hoholo - ho hanyetsa le ho thibela oxidation. Bophelo ba tšebeletso ea sehlahisoa sa SiC bo bolelele ba makhetlo a 4 ho isa ho a 5 ho feta 92% ea lisebelisoa tsa alumina. MOR ea RBSiC ke 5 ho linako tse 7 tsa SNBSC, e ka sebelisoa bakeng sa libopeho tse rarahaneng haholoanyane. Ts'ebetso ea quotation e potlakile, thomello e joalo ka ha e ts'episitsoe 'me boleng ha bo na letho. Re lula re phehella ho phephetsa lipakane tsa rona le ho khutlisetsa lipelo tsa rona sechabeng.
