Emakhoneni ezinkundla zokucobelelana ngolwazi zasefekthri nezokuthutha zasezimayini, kukhona “indima” ebalulekile kodwa enganakwa kalula - ipayipi lokudlulisa. Zithutha amaminerali, udaka namakhemikhali okusetshenziswa usuku nosuku, futhi izindonga zazo zangaphakathi zihlala zikhungethwe yizinto ezisetshenziswayo. Ngokuhamba kwesikhathi, zijwayele ukuguga, ukuvuza, okungathinti nje kuphela ukukhiqiza kodwa futhi kudinga ukulungiswa okubizayo nokushintshwa. Ulayini wepayipi ongagugi we-silicon carbide esizokhuluma ngawo namuhla ufana nokubeka ungqimba “lwezikhali zempi ezingabonakali” emapayipini avamile, kuxazululwe buthule le nkinga enkulu.
Omunye angase abuze, yinii-silicon carbide? Eqinisweni, akuyona imfihlakalo. Empeleni, iwumsebenzi owenziwe ngokwenziwa owenziwe nge-carbon ne-silicon, enobulukhuni okwesibili kunedayimane.
Uma kuqhathaniswa nodonga lwangaphakathi lwamapayipi ajwayelekile, ubulukhuni be-silicon carbide lining buphakeme izikhathi eziningana. Lapho izinhlayiya zensimbi ecijile kanye nodaka olugeleza ngesivinini esikhulu kugeza odongeni lwangaphakathi, i-silicon carbide ingasebenza njengesihlangu ukuze ivimbe ukungqubuzana futhi ivimbele ukuklwebheka noma amabobo ukuthi angenzeki kalula. Ngisho nokuthuthwa kwesikhathi eside kwezinto zokugqoka okuphezulu, udonga lwayo lwangaphakathi lungahlala luyisicaba futhi lubushelelezi, ngaphandle kokuba lube lukhulu noma lube brittle ngenxa yokugqoka, lwandise kakhulu impilo yesevisi yepayipi.
Ngaphezu kokumelana nokugqoka, iphinde ibe nekhono elifihliwe - 'ingakwazi ukumelana nokwakhiwa'. Emkhiqizweni wezimboni, izinto ezidluliswayo ngokuvamile azigcini nje ngokuthi "umhlabathi", kodwa zingase zithwale amazinga okushisa aphezulu kanye nokugqwala kwe-acid-base. Ngokwesibonelo, emkhakheni wobunjiniyela bamakhemikhali, ezinye izinto zinokugqwala okuqinile, futhi ulwelwesi lwamapayipi avamile lugqwala kalula futhi luxebuke; Embonini ye-metallurgical, izinto ezisezingeni eliphezulu zokushisa zingabangela ukuguquguquka nokuhluleka kolwelwesi. I-silicon carbide lining ingamelana namazinga okushisa angamakhulu ambalwa degrees Celsius futhi imelane nokuguguleka kwemithombo yezindaba ene-acidic ne-alkaline, igcine ukusebenza okuzinzile kunoma iyiphi "indawo enzima".
Kumabhizinisi, izinzuzo ezilethwa yilo lining elincane zibonakala kakhulu: asikho isidingo sokuvala njalo nokushintsha amapayipi, ukunciphisa ukulahlekelwa okubangelwa ukuphazamiseka kokukhiqiza; Asikho isidingo sokutshala imali ngokuphindaphindiwe ezindlekweni zesondlo, singagcina imali eningi ngokuhamba kwesikhathi; Okubaluleke nakakhulu, ingaqinisekisa ukuthuthwa kwezinto ezibushelelezi futhi igweme izingozi zokuphepha nezinkinga zemvelo ezibangelwa ukuvuza kwamapayipi.
Kusukela ekufakweni kwamapayipi okungacacile kuye “ethuluzini elingagugi” elivikela ukukhiqizwa kwezimboni, inani le-silicon carbide lamapayipi angagugi lilele emandleni awo “okuxazulula izinkinga ezinkulu ngemininingwane emincane”. Emabhizinisini aphishekela ukukhiqiza okuphumelelayo nokuzinzile, ukukhetha akukhona nje ukuthuthukiswa kwemishini, kodwa futhi ukucatshangelwa kwesikhathi eside kokusebenza kahle kokukhiqiza nokulawula izindleko.
