Kwiminyaka yakutshanje, iintlobo ezintsha zezinto eziphikisayo - irabha ye-silicone ye-ceramic refractory kunye nebhanti ye-ceramic refractory ye-silicone yerabha ehlanganisiweyo isetyenziselwa ukuveliswa kweentambo eziphikisayo, ezixazulula iingxaki zezi ntlobo zimbini zingasentla.iintambo eziphikisayo.
1. Iimpawu ze-ceramic refractory silicone rubber
Irabha ye-silicone ye-ceramic refractory yenziwe ngokongeza izinto ezisebenzayo kwi-vulcanization yobushushu obuphezulu (HTV) irabha ye-silicone.Ukumelana nobushushu obuphezulu kunye nezantsi, ukumelana nokuguga kwe-ozone, ukuxhathisa ukuguga kwemozulu, ukusebenza kakuhle kokufakelwa kombane kunye nokusebenza kakuhle kokusebenza;phantsi kobushushu obuphezulu bokutshiswa komlilo, umxube we-silicone yerabha ehlanganisiweyo edityaniswe nezinto ezisebenzayo yenza umaleko okhuselweyo we-ceramic we-ceramic, unokudlala indima yokwahlula amadangatye, ukuthintela umlilo, ukugquma, ukugquma ubushushu, ukugqunywa kwamanzi kunye nokumelana nokuzamazama komhlaba, oko kuqinisekisa ukugudiswa komlilo. ukuhamba kombane kunye nonxibelelwano kwimeko yomlilo.
2. Indlela yokumelana nomlilo kunye nokumelana nomlilo werabha ye-ceramic refractory silicone
Izinto eziqhelekileyo zepolymer ziguqulwa zibe luthuthu emva kokuvutha komlilo, kwaye azikwazi ukuguqulwa zibe zizinto ze-ceramic;Irabha ye-ceramic engenamlilo kunye ne-refractory silicone irabha inokutshizwa kubushushu obuphezulu obungenadanga obungaphezu kwama-500.°C kunye nokukhutshwa kwedangatye ngaphezulu kwe-620°C. Okukhona ixesha lokukhupha igazi lide kwaye liphezulu iqondo lobushushu, kokukhona kucaca ngakumbi isiphumo seceramization sibonakala, kwaye iqondo lobushushu le-ablation linokufikelela kuma-3000.℃;Irabha ye-silicone ekwaziyo ukumelana nomlilo kunye ne-refractory inokuveliswa kusetyenziswa izixhobo eziqhelekileyo zokulungisa irabha.Imveliso egqityiweyo inazo zonke iipropathi zerubha ye-silicone kwaye inokusebenza kakuhle.
Yinto edibeneyo enokuthi ifakwe kwi-porcelainized kwiqondo lokushisa eliphezulu ngokudibanisa irabha ye-silicone.Igcina zonke iimpawu zerubha ye-silicone kwiqondo lokushisa.Xa udibana nobushushu obuphezulu obungenamlilo obungaphezulu kwama-500℃kunye nokutshiswa kwedangatye ngaphezulu kwama-620℃, iya kuguqulwa ibe yi-ceramics ye-inorganic.Olu hlobo lwezinto ze-ceramic zineenzuzo zokugquma kwe-ceramic, ukugquma ubushushu, ukugquma umlilo, ukugquma kwamanzi, ukuxhathisa ukothuka, kunye nokuncipha kobunzima obuncinci be-thermal.
Irabha ye-ceramic ekwazi ukumelana nomlilo kunye ne-refractory ye-silicone ayinayo ityhefu kwaye ayinavumba kwiqondo lobushushu begumbi, inokuthamba okuhle kunye nokunwebeka, kunye nokumelana nokufuma okugqwesileyo kunye nokuxhathisa ukufunxa amanzi.Ineempawu zerabha ye-silicone.Irabha ye-silicone ye-ceramic refractory inokutshiswa ngamadangatye Emva kokutshisa i-2-4 imizuzu, iqala ukucwina kwigobolondo elikhuni le-ceramic-like armored.Umaleko we-insulating weli qokobhe le-ceramic eliqinileyo elifana ne-armored linokuthintela ngokufanelekileyo idangatye ukuba lingaqhubeki livutha;kwaye yophukile ngokupheleleyo emva kokutshiswa malunga nemizuzu emi-2.Umsi, kwinkqubo elandelayo yokukhupha, akukho msi ngokwawo uya kuveliswa;umsi owenziwe kwimizuzu emi-2 yokuqala nayo ayinayo i-halogen, ayinayo ityhefu, kwaye ayinabungozi;Umsi ubukhulu becala ngumsi oqinileyo oveliswe emva kokutshiswa kwesilicon ephilayo, Isixhobo esitshisiweyo esifana ne-ceramic liqokobhe lobusi eliqinileyo nelifanayo.Into enjalo ine-insulation egqwesileyo, ukugquma ubushushu, ukumelana nomlilo kunye nokumelana nomlilo, kwaye inokumelana nokothuka kunye nokungcangcazela, kunye nokuthintela ukungena kwamanzi.Iqinisekisa ukuhamba kakuhle komgca kwimeko yokutshiza kunye ne-vibration.
Ibhanti edibeneyo yerabha ye-ceramic refractory
Iteyiphu ehlanganisiweyo yerabha yerabha eyenziwe ngerabha yenziwe ngokuqhoboshela irabha ye-ceramic enganyangekiyo kunye ne-refractory yerabha ye-silicone kwilaphu le-fiber yeglasi ekwazi ukumelana nobushushu obuphezulu ngokobungqingqwa obuthile ngenkqubo yokudibanisa, emva kokusikwa, kunye nokuyisonga kwi-fiber-resistant. kunye nentambo yombane kunye nentambo.
Iimpawu ze-ceramic refractory irabha ye-silicone kunye nebhanti ehlanganisiweyo yerabha ye-ceramic refractory:
1. Ukutshatyalaliswa kombane okugqwesileyo: kunokufikelela kwiipropati zombane ze-XLPE kunye ne-EPDM: ukuxhatshazwa kwevolumu kunokufikelela kwi-2×1015Ω·cm, amandla okuphuka 22-25KV / mm, ilahleko yedielectric tangent 10-3, idielectric engaguqukiyoδ: 2-3.5, ingasetyenziselwa ukugquma;

9. Ubutyhefu bomsi okwangoku bukwibakala eliphezulu le-ZA1 phakathi kwezixhobo zepolymer, ngakumbi izinto zekhebula, oko kukuthi, umsi emva kokutsha utsalwa ziimpuku imizuzu engama-30, kwaye akukho tshintsho kwiintsuku ezintathu;
10. Ukufudumala kakuhle ukufudumala ukushisa, i-thermal conductivity 0.09W / Mk, ngakumbi emva kokutshatyalaliswa, ingaphakathi lifana ne-honeycomb shape, enokumelana nomlilo okungcono kunye nokushisa ukushisa;
11. Ukutshatyalaliswa komlilo okulungileyo: ukutshatyalaliswa komlilo kunokufikelela kwinqanaba le-UL94V-0, i-oxygen index ingaphezulu kwe-28, kwaye iphakamileyo inokufikelela ngaphezu kwe-40.5;
12. Emva kokutshiswa kobushushu obuphezulu, kunokutshizwa kwimilo ye-ceramic ukwenza isikrweqe esinzima se-ceramic ukukhusela ukuhamba kakuhle kwesekethe.Le yeyona nto "yenguquko" yerabha ye-ceramic enganyangekiyo kunye ne-refractory.Ukuphakama kweqondo lobushushu, ixesha lokukhutshwa lide, kunye nesikrweqe seceramic Ukuqina komzimba;ingcono kune-mica tape, eba nzima kwaye i-brittle emva kokutshisa kwaye iwele ngokulula;
13. I-wire-resistant kunye ne-fire-resistant-resistant wire kunye nekhebula eveliswa nge-ceramic-proof-proof kunye ne-rubber ye-silicone ekwazi ukumelana nomlilo kunye ne-ceramic-proof-proof and fire-resistant silicone rubber compound tape inokufikelela kumgangatho we-A-level ye-GB12666.6, oko kukuthi, ukutshisa kwidangatye le-950 ~ 1000℃kuba 90min, 3A fuse Akukho fusing;inokufikelela kwinqanaba eliphezulu le-CWZ ye-Bhritane BS6387, oko kukuthi, i-C-ukutsha kwidangatye kwi-950°C iiyure ezi-3, W-isitshizi samanzi, Z-ukungcangcazela;
14. Uxinzelelo oluncinci (1.42-1.45), ixabiso eliphantsi kunye nokusebenza kweendleko eziphezulu;
15. Ngokusekelwe kwiimpawu ezingentla apha, inokutshintsha ngokupheleleyo i-mica tape, kungekhona kuphela kwi-low-voltage-resistant-resistant kunye ne-fire-resistant cables, kodwa kunye ne-medium and high-voltage-resistant fire and fire-resistant cables.
