Kwimveliso yemizi-mveliso, imibhobho ifana “nemithambo yegazi” yezixhobo, enoxanduva lokuthutha izinto “ezinobushushu obushushu” njengesanti, igrabile, kunye neegesi zobushushu obuphezulu. Ngokuhamba kwexesha, iindonga zangaphakathi zemibhobho eqhelekileyo ziguga ngokulula kwaye zinokuvuza, zifuna ukulungiswa rhoqo kunye nokutshintshwa, kwaye zinokulibazisa inkqubela phambili yemveliso. Enyanisweni, ukongeza umaleko "wempahla yokukhusela ekhethekileyo" kumbhobho unokusombulula ingxaki, eyona ntoi-silicon carbide pipeline liningsiza kuthetha ngayo namhlanje.
Abanye abantu banokubuza, yintoni kanye kanye imvelaphi ye-silicon carbide ceramics evakala ngathi "hardcore"? Ukubeka nje ngokulula, yimathiriyeli ye-ceramic eyenziwe ngezinto eziqinileyo ezifana ne-silicon carbide ngeenkqubo ezikhethekileyo, kwaye eyona nto inkulu "yokuhlala": ukuqina kwayo okwesibini kwidayimane, kwaye inokumelana nokukhukuliseka kwesanti kunye negrabile kunye nezinto ezidliwayo ngokuthe gqolo, ngokungafaniyo neelitha zentsimbi eziqhelekileyo ezithanda ukugqwala kwaye zigugile, kwaye ziyakwazi ukumelana nobushushu obuphezulu kunye neempembelelo zeplastiki.
Undoqo wokufaka i-silicon carbide lining kwimibhobho kukongeza "umqobo owomeleleyo" kudonga lwangaphakathi. Xa ufaka, akukho mfuneko yokwenza umzamo omkhulu. Uninzi lwexesha, iziqwenga ze-silicon carbide zeceramic ezenziwe kwangaphambili zibotshelelwa kudonga lwangaphakathi lombhobho kunye nezinto ezincamathelayo ezikhethekileyo ukwenza umaleko opheleleyo okhuselayo. Lo maleko 'wesithintelo' unokungabonakali ungqindilili, kodwa umsebenzi wawo uyasebenza ngakumbi:
Okokuqala, 'kukunganyangeki ngokupheleleyo'. Nokuba ihambisa amasuntswana e-ore aneencam ezibukhali okanye i-slurry ebaleka ngesantya esiphezulu, umphezulu we-silicon carbide lining ugudile ngakumbi. Xa izinto zidlula, ukungqubuzana kuncinci, okungonakalisi nje kuphela i-lining, kodwa kunciphisa ukuchasana ngexesha lokuthuthwa kwezinto eziphathekayo, okwenza ukuthutha kube lula. Imibhobho eqhelekileyo inokufuna ukulungiswa emva kwesiqingatha sonyaka igugile kwaye ikrazukile, ngelixa imibhobho ene-silicon carbide lining inokwandisa ngokubonakalayo ubomi bayo benkonzo, inciphise inkathazo kunye neendleko zokutshintsha umbhobho ophindaphindiweyo.
Emva koko kukho "ukuxhathisa ukubola kunye nomgangatho ophezulu wokumelana nomgca wesibini". Kwiimeko ezininzi zemizi-mveliso, izinto ezihanjiswayo zithwala amacandelo e-asidi kunye ne-alkali, kwaye ubushushu abukho phantsi. Iilinen eziqhelekileyo zidla ngokutya kwaye ziqhekeke, okanye zikhubazeke ngenxa yokubhaka okuphezulu kobushushu. Kodwa i-silicon carbide ceramics ngokwazo ineekhemikhali ezizinzile kwaye ayiloyiki ukukhukuliseka kwe-asidi kunye ne-alkali. Kwanaxa zibekwe kumaqondo obushushu angamakhulu aliqela ngokukaCelsius, ziyakwazi ukugcina imo ezinzileyo, zizenze zilungele ukusetyenziswa kwemibhobho “kwiindawo ezirhabaxa” ezifana nemichiza, isinyithi, nemigodi.
Enye inqaku elibalulekileyo "likhululekile kwaye alisebenzi". Imibhobho ehlanganiswe ne-silicon carbide ayifuni ukuvala rhoqo ukugcinwa, kwaye kulula ukuyigcina - umphezulu awuhambelani nokulinganisa okanye ukuxhoma izinto, kwaye kufuneka zicocwe kancinci rhoqo. Kumashishini, oku kuthetha ukunciphisa umngcipheko wokuphazamiseka kwemveliso kunye nokugcina iindleko ezininzi zokugcinwa kwabasebenzi kunye nezinto eziphathekayo, ezilingana "nofakelo lwexesha elinye, ukukhululeka kwexesha elide".
Abanye abantu banokucinga ukuba i-lining ehlala ixesha elide ibiza kakhulu? Enyanisweni, ukubala "i-akhawunti yexesha elide" kucacile: nangona iindleko zokuqala ze-lining eziqhelekileyo ziphantsi, kufuneka zitshintshwe rhoqo kwiinyanga ezintathu ukuya ezintlanu; Utyalo-mali lokuqala lwe-silicon carbide lining luphezulu kancinci, kodwa lunokusetyenziswa iminyaka eliqela, kwaye ixabiso eliphakathi ngosuku lisezantsi. Ngaphezu koko, inokuphepha ilahleko yemveliso ebangelwa ngumonakalo wepayipi, kwaye indleko-esebenzayo ngokwenene iphezulu kakhulu.
Kule mihla, i-silicon carbide pipeline lining iye ngokuthe ngcembe ibe "isisombululo esikhethwayo" sokhuseleko lwemibhobho yoshishino, ukusuka kwiintsila ezihambisa imibhobho emigodini, ukuya kwimibhobho yezinto ezonakalisayo kushishino lweekhemikhali, ukuya kwimibhobho yerhasi enobushushu obuphezulu kushishino lwamandla, ubukho bayo bunokubonwa. Ukubeka nje ngokulula, kufana "nomlindi wobuqu" wemibhobho, egcina ngokuthula ukusebenza kakuhle kwemveliso yemveliso kunye nobunzima kunye nokuqina kwayo - oku kukwabangela ukuba iinkampani ezininzi zizimisele ukuxhobisa imibhobho ngale "mpahla yokukhusela ekhethekileyo".
