Kwimveliso yemizi-mveliso, imibhobho ifana “nemithambo yegazi” ethwala izinto, kodwa inokujongana nezisongelo zempilo ezifana nokuguguleka, ukubola, kunye nobushushu obuphezulu. Imibhobho eqhelekileyo idla ngokungakwazi ukumelana nayo ixesha elide, kwaye ukulungiswa rhoqo akupheleli nje ekulibaziseni imveliso kodwa kwandisa neendleko. Ukuvela kweumgca wepayipi ye-silicon carbideifake "isuti yokukhusela eqinileyo" kwimibhobho yemizi-mveliso, isombulula ezi ngxaki ngokulula.
Abanye abantu banokuba nomdla wokuba, yintoni kanye kanye i-silicon carbide? Enyanisweni, yinto ekhethekileyo ye-ceramic eyenziwe yi-silicon kunye ne-carbon, ngokwemvelo ithwala i-gene "eqinileyo nehlala ixesha elide". Ubulukhuni bayo buphezulu kakhulu, bulandela idayimani kuphela. Xa kuthuthwa umgubo weminerali kunye nezinto ze-slurry kubomi bemihla ngemihla, nokuba kukungqubana okukhulu kunzima ukushiya amanqaku kumphezulu wayo. Ngokungafaniyo nemibhobho yesinyithi eqhelekileyo, kungekudala iya kugaywa ibe ncinci kwaye igqobhoke. Kwaye iipropati zayo zekhemikhali zizinzile ngokukodwa, nokuba yi-acid enamandla kunye ne-alkali chemical media okanye i-slurry ebolayo, azinakukwazi ukuyigqwala ngokulula, ziphephe umngcipheko wokugqwala kunye nokuvuza kwepayipi kwiingcambu.
Ukumelana nobushushu obuphezulu kukwayinzuzo enkulu ye-silicon carbide pipeline lining. Kwimveliso yemizi-mveliso, izinto ezininzi kufuneka zithuthwe kwiindawo ezinobushushu obuphezulu. Iipayipi eziqhelekileyo zinokuguquguquka kwaye ziguge phantsi kokubhaka ixesha elide kubushushu obuphezulu, nto leyo echaphazela ukhuseleko lokuthuthwa. Kwaye i-silicon carbide lining inokumelana nobushushu obuphezulu kakhulu, nokuba yi-flue gas enobushushu obuphezulu okanye izinto ezishushu, inokuthuthwa kakuhle ngozinzo olupheleleyo.
Xa kuthelekiswa neendlela zemveli zokukhusela imibhobho, i-silicon carbide lining nayo ineempawu ezingenaxhala. Ubume bayo buxinene, umphezulu uthambile kwaye uthe tyaba, kwaye akulula ukuxhoma okanye ukukala xa kuthuthwa izinto. Inokunciphisa intsalela yezinto kunye nokuvaleka, kwaye igcine ukusebenza kakuhle kokuthutha kuzinzile. Kwangaxeshanye, uxinano lwayo luphantsi kakhulu kunolwesinyithi, kwaye uludwe lombhobho aluyi kunyusa kakhulu ubunzima bubonke. Nokuba kukufakelwa okanye ukulungiswa kamva, kulula ngakumbi kwaye kunokunciphisa umthwalo wokufakwa kwemibhobho, ukuziqhelanisa neemeko ezinzima ngakumbi zoshishino.
Kubalulekile ukukhankanya ukuba ukungangeni kweekhemikhali kwe-silicon carbide ngokwayo kuyayithintela ukuba ingasabelani nezinto ezithuthwayo. Nokuba zizinto ezifunekayo kubumsulwa obuphezulu, akukho mfuneko yokukhathazeka ngongcoliseko olubangelwa kukuxubana kwezinto ezifakwe ngaphakathi. Nokuba zizinto eziluhlaza ezintle kwishishini leekhemikhali okanye ziimpuphu ezicocekileyo kakhulu kwishishini elitsha lamandla, zinokuthuthwa ngokuzithemba. Esi sisizathu esibalulekileyo sokuba amashishini amaninzi akwizinga eliphezulu azimisele ukuzikhetha.
Kule mihla, umgca wepayipi ye-silicon carbide uye waba "yingcali yokukhusela" kwicandelo lothutho lwemizi-mveliso, ukusuka ekuthuthweni kwezinto ezirhabaxa kwimigodi kunye namandla obushushu ukuya ekuthuthweni okuphakathi kwiikhemikhali kunye neebhetri ze-lithium, ubukho bayo bunokubonwa. Isebenzisa ukusebenza kwayo okugqwesileyo ukunceda amashishini anciphise amaxesha okugcinwa kwemibhobho, yandise ubomi benkonzo yezixhobo, kwaye yenze ukuthuthwa kwemizi-mveliso kube lula kwaye kukhuseleke.
Njengabasebenzi abagxile kwicandelo le-silicon carbide ceramics zoshishino, besisoloko siphucula umgangatho wee-silicon carbide pipeline liners, sisebenzisa iimveliso ezihlangabezana ngcono neemfuno zoshishino ukuqinisekisa imveliso ezinzileyo kumashishini ahlukeneyo. Vumela olu maleko "lweempahla ezikhuselayo eziqinileyo" lukhusele "umgca" wothutho olungakumbi lwemizi-mveliso.
