Ukwakhiwa okuqinile nge-silicon carbide tube

I-Silicon Carbide Tube (I-SSIC) Ingxenye ehlaba umxhwele ye-ceramic eyaziwa ngobulukhuni bayo obuvelele nokuqina okushisayo, Ngaphezu kokwaziwa kabanzi ngokumelana kwayo okuphakeme kokuqina kanye nokungena kwamakhemikhali.

Amashubhu we-SSIC angatholakala ezinhlobonhlobo zezicelo zezimboni. Ngokuqondene, Lezi zixazululo zeTubing zihamba phambili lapho zisetshenziswa ezingxenyeni zezimboni zamandla ezidinga ukumelana nokuqina kokugqwala nokuvikelwa kokugqwala.

Ubunzima

I-Silicon Carbide ingenye yezinto ezinzima kunazo zonke emhlabeni, Ukuqhayisa ukukalwa kanzima kwe-mohs 13. Kusemuva kwe-Diamond ne-Boron Carbide kuphela ukukala kanzima. Ngenxa yokuqina kwayo okwedlulele, I-Silicon Carbide yenza ukukhetha okuhle kwezinto ezibonakalayo kwezicelo lapho kungenzeka khona ukucindezela noma izingcindezi eziphakeme zemishini.

Njengoba inamandla amakhulu acindezelayo, ubunzima, kanye ne-modulus yezimpawu zokunwebeka ezikwenza kufanelekile ezinhlelweni zokuvikela ezinamabala, Izinto zokwenziwa ze-Ceramic ziyikhenyo lapho ukhetha izinto zezempi zezinhlelo zokuvikela ama-ballistic. Bangakwazi ukumisa ama-projectiles ngesikhathi sokungena ngenkathi besamunca amandla angeziwe avumela ukuthi anikeze ukuvikeleka okusebenzayo ngesisindo somkhiqizo sonke ngokuqhathaniswa nezinye izinketho ze-armor.

Ubulukhuni obuqinile be-silicon Carbide kanye nokunwebeka okuphansi okushisayo kuvumela ukuthi kusetshenziswe kwizicelo ezidinga ukuphindaphindwa njengezinsimbi zomlilo. Ngaphezu kwalokho, ukumelana kwayo ngokumelene namazinga okushisa aphezulu, Ukugqwala kanye nokuhlasela kwamakhemikhali kwenza kube ukukhetha okubonakalayo okubonakalayo. Ngokuhambisana nezakhiwo zayo ezinamandla, I-Silicon Carbide yenza ukukhetha okubonakalayo okubonakalayo kokusetshenziswa okuningi kwezimboni nezentengiso.

Ukumelana nokugqwala

I-Silicon Carbide ingenye yezinto ezinzima kakhulu ze-ceramic emakethe, Ukunikeza ukugqwala okuhlukile, ukuphakamayo, ukuguguleka nokungamelana nokugqokwa kwenhliziyo. Ngaphezu kwalokho, Izinga layo eliphansi lokunwebeka, Inani le-modulus ephezulu ye-modulus kanye nokumelana okuhlukile kwamakhemikhali kwenza kufanelekile ukusetshenziswa ezicelo ezifunwayo zokwakha.

I-SIC ecindezelekile ene-main ifakazele ukumelana kwayo ekuhlaselweni kwe-acid kuyo yonke imithombo – hydrochloric, sulfuric kanye nama-phosphoric acid; izisekelo nama-solvents; Zonke izinto ezi-oxidizing media kanye nama-ascive acid afana ne-lime ne-nitric acid – Ngokumelana nomthelela omuhle kakhulu ngokumelene nezinto zokwenziwa kwezindlu kanye nokumelana okuphezulu kwecala.

Amashubhu we-SSIC asetshenziswa emhlambini wokushisa wokushisa we-carburshing, izinqubo ze-nitriding ne-anveling ngenxa yokumelana kwazo okuphezulu ngokumelene ne-oxidation kanye nokugqwala nokuvimbela ukumelana. Ngaphezu kwalokho, Lawa mashubhu asebenza kahle anika amandla ukufudumala okusheshayo nemijikelezo epholile okuholele ekutheni i-Long Service ihlala enze i-SSIC ibe yisixazululo sesikhathi eside sokutshala imali esheshayo. Baphinde baqashelwa njengababhekene nobuso bokubopha amaphampu ezindaweni ezibandakanya ukucubungula amakhemikhali / izindawo zokucwengisisa, Ukusebenza kwezimayini kanye ne-pulp / amaphepha ecubungula izitshalo.

Ukuvuselelwa okushisayo

Onjiniyela kanye nabaqambi babekade bebeka phambili ukubekeka ama-Silicon Carbide Cardings ama-Cardings ahlanganisiwe wamandla wenuzi ukuze anciphise ukumuncwa kwe-neutron ngenkathi enikeza ukumelana no-steam oxidation, Ukugcinwa kwamandla okushisa okuphezulu ngemuva kokuvezwa kwe-neutron nokugcinwa kwamandla ngesikhathi sokufakelwa kwe-neutron [1-4]. Ngeshwa, Ukusebenza okushisayo kuthole ukucatshangelwa okuncane kakhulu, Yize imiphumela yayo ingathinta kakhulu indlela yokushisa kawoyela kanye nesimo sokuxineka.

Izici ze-SSIC ezifakwe ngaphansi kwe-SSIC zibe sezingeni eliphansi kakhulu le-oxidation, okwenza kube lula ngezindawo eziphakeme zokushisa ezinamazinga okushisa aguqukayo. Ngaphezu kwalokho, Ukunwebeka kwalo okuphansi okuphansi kugcina ubukhulu bezinzimo ezinzile naphezu kokushisa okungazelelwe kwamazinga okushisa.

Ama-Hexoloy se amashubhu aqanjwe kahle egobolondweni kanye ne-tube ukushisa okushisa asetshenziselwa ukukhiqiza ingilazi yokuntanta yezinqubo zamakhemikhali ezidinga umthetho wokushisa oqondile, njengokukhiqiza ngezinqubo zokukhiqiza amakhemikhali ezinjengalezo ezibandakanya ukuvutshelwa. Ukuqhutshwa kwabo okuphezulu okuphezulu kwenza ukuhlukaniswa okusheshayo kokushisa kubhavu wengilazi ngaphandle kwesidingo sezinhlelo ezinkulu nezinphonguzo ezibizayo, okuholela ezinqubweni ezithembekile ezenziwa ngokuthuthuka okusebenzayo.

Isisindo

I-Silicon Carbide Isithando Ishubhu sijuluka ukumelana namandla amakhulu, Ukwenza kube yizinto ezinhle kakhulu zokulwa namafutha kagesi, I-Metallurlical Sining Fourse, Izinqubo ezingenzi lutho zensimbi zensimbi kanye nemisebenzi engekho emthethweni yensimbi. Ngaphezu kwalokho, Ukuvuselelwa kwayo okushisayo kanye nokumelana nomthelela kwenza kube yimpahla ebalulekile.

Izakhiwo eziphansi zokunwebeka ze-ophon Alpha Carbide ze-APPA, njenge-blast nozzles. Ngokwesibonelo, Ukusetshenziswa kwayo kunempilo yesikhathi eside (50% ngaphezu kwe-tungsten carbide), amanani entengo ephansi kanye nokumelana okuhluke ngokweqile.

I-SIC iyindlela enhle kunazo zonke yezinto ezibonakalayo ze-acid Spray nozzles nezinye izingxenye ezivezwe ezindaweni ezinokhahlo ngenxa yokuphikiswa kwayo okuhle nokugqwala. Ukuqina nge-chromium kanye ne-molybdenum izengezo zingangenisa ukuqina kwazo; nokho, Lokhu kwandisa kakhulu izindleko ezibonakalayo. Isisindo esiphansi sikaSic senza ukuthi ilungele ikakhulukazi izinhlelo zokusebenza lapho kunemikhawulo yesikhala nemisindo khona, kufaka phakathi ama-rocket motors nezinhlelo zokuvikela izikhali ezihlanganisiwe.
