Kwimveliso yemizi-mveliso, iipayipi zifana “nemithambo yegazi” yezixhobo, ezinoxanduva lokuthutha izinto “ezishushu” ezifana nesanti, ilitye, kunye neegesi ezishushu kakhulu. Ekuhambeni kwexesha, iindonga zangaphakathi zeepayipi eziqhelekileyo ziyaguga lula kwaye zinokuvuza, zifune ukulungiswa rhoqo kunye nokutshintshwa, kwaye zinokulibazisa inkqubela phambili yemveliso. Enyanisweni, ukongeza umaleko “weempahla zokuzikhusela ezikhethekileyo” kwipayipi kunokusombulula ingxaki, eyiumgca wepayipi ye-silicon carbideSiza kuthetha ngayo namhlanje.
Abanye abantu banokubuza, yintoni kanye kanye imvelaphi yee-silicon carbide ceramics ezivakala ngathi "ziqinile"? Ngamafutshane, sisixhobo se-ceramic esenziwe ngezinto eziqinileyo ezifana ne-silicon carbide ngeenkqubo ezikhethekileyo, kwaye uphawu lwayo olukhulu "kukuqina": ubulukhuni bayo bulandela idayimani kuphela, kwaye inokumelana nokukhukuliseka kwesanti kunye negrabile kunye nezinto ezirhabaxa ngokuthe chu, ngokungafaniyo nee-metal liners eziqhelekileyo ezidla ngokugqwala nokuguguleka, kwaye ikwamelana nobushushu obuphezulu kunye nefuthe kunee-plastic liners.
Eyona nto iphambili yokufaka i-silicon carbide lining kwimibhobho kukongeza "umqobo oqinileyo" eludongeni olungaphakathi. Xa uyifaka, akukho mfuneko yokwenza umgudu omkhulu. Uninzi lwexesha, iziqwenga ze-silicon carbide ezenziwe ngaphambili zibotshelelwa eludongeni olungaphakathi lombhobho ngee-adhesives ezikhethekileyo ukuze zenze umaleko opheleleyo wokukhusela. Olu 'maleko' 'womqobo' lusenokungabonakali lubanzi, kodwa umsebenzi walo uluncedo kakhulu:
Okokuqala, 'kukumelana nokuguguleka ngokupheleleyo'. Nokuba kukuthutha amasuntswana e-ore anemiphetho ebukhali okanye i-slurry ehamba ngesantya esiphezulu, umphezulu we-silicon carbide lining uthambile ngakumbi. Xa izinto zidlula, ukungqubana kuncinci, okungagcini nje ngokonakalisa i-lining, kodwa kunciphisa ukumelana ngexesha lokuthuthwa kwezinto, okwenza ukuthuthwa kube lula. Iipayipi eziqhelekileyo zinokufuna ukulungiswa emva kwesiqingatha sonyaka sokuguguleka, ngelixa iipayipi ezine-silicon carbide lining zinokuyandisa kakhulu ubomi bazo benkonzo, zinciphise ubunzima kunye neendleko zokutshintshwa kweepayipi eziphindaphindwayo.
Emva koko kukho "ukuxhathisa ukugqwala kunye nokumelana nobushushu obuphezulu kunye nomgca ophindwe kabini". Kwiimeko ezininzi zoshishino, izinto ezihanjiswayo ziphethe izinto ezirhabaxa ezifana ne-asidi kunye ne-alkali, kwaye ubushushu abuphantsi. Iingqiniba eziqhelekileyo ziyagqwala kwaye ziqhekeke, okanye ziguqulwe kukubhaka okushushu okuphezulu. Kodwa ii-silicon carbide ceramics ngokwazo zineempawu zeekhemikhali ezizinzileyo kwaye azoyiki ukukhukuliseka kwe-asidi kunye ne-alkali. Nokuba zibekwe kumaqondo obushushu aphezulu angama-degrees Celsius angamakhulu aliqela, zinokugcina imo ezinzileyo, ezenza zilungele ukusetyenziswa kwemibhobho "kwiindawo ezinzima" ezifana neekhemikhali, i-metallurgical, kunye nemigodi.
Enye ingongoma ebalulekileyo kukuba “akukho xhala kwaye akukho bunzima”. Iipayipi ezifakwe i-silicon carbide azifuni ukuvalwa rhoqo ukuze zilungiswe, kwaye kulula nokuzilungisa – umphezulu awukho lula ukukhaba okanye ukuxhonywa kwezinto, kwaye kufuneka zicocwe kancinci rhoqo. Kumashishini, oku kuthetha ukunciphisa umngcipheko wokuphazamiseka kwemveliso kunye nokonga iindleko ezininzi zomsebenzi kunye nezinto, ezilingana “nokufakelwa kube kanye, okungenaxhala ixesha elide”.
Abanye abantu banokucinga ukuba i-lining eqinileyo kangaka ibiza kakhulu? Enyanisweni, ukubala "iakhawunti yexesha elide" kucacile: nangona ixabiso lokuqala le-lining eqhelekileyo liphantsi, kufuneka itshintshwe rhoqo kwiinyanga ezintathu ukuya kwezintlanu; Utyalo-mali lokuqala lwe-lining ye-silicon carbide luphezulu kancinci, kodwa lungasetyenziswa iminyaka eliqela, kwaye ixabiso eliqhelekileyo ngosuku liphantsi. Ngaphezu koko, inokuthintela ilahleko yemveliso ebangelwa kukonakala kwemibhobho, kwaye ukusebenza kakuhle kweendleko kuphezulu kakhulu.
Kule mihla, umgca wepayipi ye-silicon carbide uye waba “sisisombululo esithandwayo” sokukhusela imibhobho yemizi-mveliso, ukusuka kwiintsalela ezithwala imibhobho emigodini, ukuya kwimibhobho yezinto ezirhabaxa kwimizi-mveliso yeekhemikhali, ukuya kwimibhobho yegesi yobushushu obuphezulu kwimizi-mveliso yamandla, ubukho bayo bunokubonwa. Ngamafutshane, ifana “nomlindi womntu” wemibhobho, ikhusela ngokuzolileyo ukusebenza kakuhle kwemveliso yemizi-mveliso ngobunzima bayo kunye nokuqina kwayo – yingakho iinkampani ezininzi zizimisele ukuxhobisa imibhobho ngale “mpahla yokuzikhusela ekhethekileyo”.
