Eminyakeni yamuva, izinhlobo ezintsha zezinto eziphikisayo - irabha ye-ceramic refractory abicah kanye nebhande le-ceramic refractory i-silicone eyinhlanganisela yerabha isetshenziswa ekukhiqizeni izintambo eziphikisayo, ezixazulula izinkinga zezinhlobo ezimbili ezingenhla.izintambo eziphikisayo.
1. Izici ze-ceramic refractory abicah rubber
Irabha ye-silicone ye-ceramic refractory yenziwa ngokwengeza izinto ezisebenzayo kurabha ye-silicone ye-vulcanization yokushisa okuphezulu (HTV).Ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokuguga kwe-ozone, ukumelana nokuguga kwesimo sezulu, ukusebenza okuhle kakhulu kokufakwa kukagesi nokusebenza kahle kokucubungula;ngaphansi kokushisa kwamalangabi okushisa aphezulu, ingxube ye-silicone eyinhlanganisela yerabha ehlanganiswe nezinto ezisebenzayo yakha isendlalelo esiqinile sokuzivikela se-ceramic, Ingadlala indima yokuhlukanisa ilangabi, ukuvimbela umlilo, ukufakwa kwe-insulation, ukushisa ukushisa, ukufakwa kwamanzi nokumelana nokuzamazama komhlaba, ngaleyo ndlela iqinisekise ukushelela. ukuhamba kukagesi kanye nokuxhumana uma kuba nomlilo.
2. Indlela yokumelana nomlilo kanye nokumelana nomlilo kwerabha ye-ceramic refractory abicah
Izinto ezivamile ze-polymer ziguqulwa zibe umlotha ngemva kokukhishwa kwelangabi, futhi azikwazi ukuguqulwa zibe izinto zobumba;Irabha ye-silicone engashisi umlilo kanye ne-refractory ingafakwa ekushiseni okungenamalangabi ngaphezu kwama-500.°C kanye nokukhishwa kwelangabi ngaphezu kuka-620°C. Uma isikhathi sokukhipha umoya siba side futhi izinga lokushisa liphakeme, umphumela we-ceramization uba sobala kakhulu, futhi izinga lokushisa lokukhipha umoya lingafinyelela ku-3000.℃;Irabha ye-silicone ekwazi ukumelana nomlilo kanye ne-refractory ingakhiqizwa kusetshenziswa imishini evamile yokucubungula irabha.Umkhiqizo oqediwe unazo zonke izakhiwo zerabha ye-silicone futhi unokucutshungulwa okuhle.
Kuyinto eyinhlanganisela engenziwa i-porcelainized ekushiseni okuphezulu ngokungeza irabha ye-silicone.Igcina zonke izici zerabha ye-silicone ekamelweni lokushisa.Lapho uhlangabezana nezinga lokushisa elingenamlilo elingaphezu kuka-500℃kanye nokukhishwa kwelangabi ngaphezu kuka-620℃, izoguqulwa ibe izitsha zobumba ezingaphili.Lolu hlobo lwe-ceramic material lunobuhle bokufakwa kwe-ceramic, ukufakwa kwe-heat insulation, ukufakwa komlilo, ukufakwa kwamanzi, ukumelana nokushaqeka, nokuncipha kwesisindo esincane esishisayo.
Irabha ye-Ceramic ukumelana nomlilo kanye ne-refractory ayinabuthi futhi ayinaphunga ezingeni lokushisa lasekamelweni, inokuthamba okuhle nokunwebeka, nokumelana nomswakama okuhle kakhulu nokumelana nokumuncwa kwamanzi.Inezici zenjoloba ye-silicone.Irabha ye-silicone ye-ceramic refractory ingashiswa ngamalangabi Ngemva kokushisa imizuzu engu-2-4, iqala ukucwilisa egobolondweni eliqinile le-ceramic-like armored.Ungqimba oluvikelayo lwaleli gobolondo eliqinile le-ceramic-like armored lingavimbela ngokuphumelelayo ilangabi ukuthi liqhubeke livutha;futhi iphukile ngokuphelele ngemva kokushiswa cishe imizuzu emi-2.Intuthu, enqubweni elandelayo yokukhishwa kwe-ablation, akukho ntuthu ngokwayo ezokhiqizwa;intuthu ekhiqizwe phakathi kwemizuzu emi-2 yokuqala nayo ayinayo i-halogen, ayinabuthi, futhi ayinabungozi;intuthu ikakhulukazi intuthu eqinile ekhiqizwa ngemva kokushiswa kwe-silicon ephilayo, Izinto ezishisiwe ezifana ne-ceramic igobolondo lekhekheba lezinyosi eliqinile nelifanayo.Into enjalo ine-insulation enhle kakhulu, ukuvikela ukushisa, ukumelana nomlilo nokumelana nomlilo, futhi ingamelana nokushaqeka nokudlidliza, futhi ivimbele ukungena kwamanzi.Iqinisekisa ukuhamba kahle komugqa esimweni sokufafaza nokudlidliza.
Ibhande eliyinhlanganisela yerabha ye-ceramic refractory
Itheyiphu eyinhlanganisela yerabha ye-ceramic refractory asilicone yenziwa ngokunamathisela irabha ye-ceramic engashi kanye ne-refractory endwangu yengilazi ekwazi ukumelana nokushisa okuphezulu ngokobukhulu obuthile ngenqubo yokubopha, ngemva kokusikwa, bese isonga entweni engashi. kanye nentambo ye-refractory nekhebula.
Izici ze-ceramic refractory irabha ye-silicone nebhande le-ceramic refractory irabha eliyinhlanganisela ye-silicone:
1. Ukufakwa kukagesi okuhle kakhulu: kungafinyelela izakhiwo zikagesi ze-XLPE ne-EPDM: ukumelana nevolumu kungafinyelela ku-2×1015Ω·cm, amandla okuphuka 22-25KV/mm, dielectric loss tangent 10-3, dielectric constantδ: 2-3.5, ingasetshenziselwa ukwahlukanisa;

9. Ubuthi bentuthu okwamanje buyibanga eliphakeme kakhulu le-ZA1 phakathi kwezinto ze-polymer, ikakhulukazi izinto zekhebula, okungukuthi, intuthu ngemva kokusha ihogelwa amagundane imizuzu engu-30, futhi alukho ushintsho phakathi nezinsuku ezintathu;
10. Ukushisa okuhle kokushisa, i-thermal conductivity 0.09W / Mk, ikakhulukazi ngemva kokukhishwa kwe-ablation, ingaphakathi liyi-uniform ye-honeycomb shape, enokumelana nomlilo okungcono nokushisa ukushisa;
11. Ukuhlehliswa komlilo okuhle: ukuvinjelwa komlilo kungafinyelela izinga le-UL94V-0, inkomba ye-oxygen ingaphezu kwe-28, futhi ephakeme kakhulu ingafinyelela ngaphezu kwe-40.5;
12. Ngemuva kokushisa okuphezulu kokushisa, kungashiswa kusimo se-ceramic ukuze kwakhiwe isivikelo esiqinile se-ceramic ukuvikela ukugeleza okushelelayo kwesifunda.Lesi isici "esiguquguqukayo" kakhulu serabha ye-ceramic engashi kanye ne-refractory abicah.Ukuphakama kwezinga lokushisa, isikhathi sokukhipha umoya siba side, kanye nezikhali zobumba Ukuqina komzimba;kungcono kune-mica tape, eba lukhuni futhi ibe brittle ngemva kokuvutha futhi iwe kalula;
13. Intambo nekhebula elingashi nokumelana nomlilo elikhiqizwe irabha ye-silicone engashi kanye ne-ceramic engashi kanye netheyiphu ehlanganisiwe yerabha yerabha engashi ingafinyelela izinga elingu-A le-GB12666.6, okungukuthi, shisa ilangabi lika-950 ~ 1000℃imizuzu engu-90, i-3A fuse Akukho ukuhlanganisa;ingaphinda ifinyelele izinga eliphezulu le-CWZ leBritish BS6387, okungukuthi, C-evutha elangabini ku-950°C amahora angu-3, W-isifutho samanzi, Z-ukudlidliza;
14. Ukuminyana okuncane (1.42-1.45), amanani aphansi nokusebenza kwezindleko eziphezulu;
15. Ngokusekelwe ezicini ezingenhla, ingakwazi ukufaka esikhundleni ngokuphelele i-mica tape, hhayi kuphela izintambo ezingaphansi kwe-voltage ezikwazi ukumelana nomlilo nezingashi, kodwa futhi nezintambo nezintambo ezingashi nomlilo eziphakathi nendawo neziphezulu.
