Kwinkqubo engundoqo yokuveliswa kwemveliso, ukuthuthwa kwezinto eziphathekayo kuhlala kujongene neengxaki ezifana nokunxiba kunye nokubola. Iipayipi eziqhelekileyo zihlala zinenkonzo emfutshane kunye neendleko eziphezulu zokugcina, ezichaphazela ukusebenza kakuhle kwemveliso. Ukuvela kweimibhobho ye-silicon carbide ekwaziyo ukunxiba, kunye nokusebenza kwabo okugqwesileyo, kuye kwaba "isixhobo" sokucombulula le ngongoma yentlungu kunye nokubonelela ngokukhuselwa kokuthutha kwamashishini.
I-Silicon carbide, njengesixhobo se-inorganic non-metallic eyenziwe ngokwenzayo, ngokwendalo inophawu "olunzima". Ukuqina kwayo kukwesibini emva kwedayimane, kwaye ukuxhathisa kwayo ukunxiba kudlula lee imibhobho yemveli efana nemibhobho yentsimbi eqhelekileyo kunye nemibhobho yeceramic. Nangona xa uthutha izinto eziphezulu zokugqoka eziqulethe inani elikhulu leengqungquthela kunye neepowder, ziyakwazi ukuxhathisa ngokulula ukukhukuliseka kunye nokwandisa ngokufanelekileyo ubomi benkonzo yeepayipi. Kwangaxeshanye, i-silicon carbide ikwanayo nokumelana nobushushu obuphezulu kunye nokumelana nomhlwa. Ayinakonakala lula ngamajelo anzima afana ne-high-temperature flue gas, i-asidi eqinile kunye ne-alkali, evumela ukuba idlale indima ezinzileyo kumashishini amaninzi afana ne-metallurgy, imboni yeekhemikhali, amandla, imigodi, njl.
Xa kuthelekiswa nemibhobho yemveli, imibhobho ye-silicon carbide enganyangekiyo ayingokuphela nje "ihlala ixesha elide", kodwa izisa iinzuzo ezibonakalayo kumashishini. Ngenxa yobude bayo obude kakhulu, amashishini akufuneki atshintshe rhoqo imibhobho, nto leyo enganciphisi nje ixesha lokuyilungisa kodwa ithoba neendleko zabasebenzi nempahla. Ukongeza, udonga lwangaphakathi lwemibhobho ye-silicon carbide igudile, inokumelana nolwelo oluphantsi, olunokunciphisa ilahleko yamandla ngexesha lothutho kunye nokunceda amashishini afezekise ukonga amandla kunye neenjongo zokunciphisa ukusetyenziswa.
Namhlanje, njengoko ukukhuselwa kokusingqongileyo okuluhlaza kuba yeyona ndlela iphambili yophuhliso lwamashishini, iingenelo ze-silicon carbide ukunxiba imibhobho zibalaseleyo. Inoluhlu olubanzi lwemithombo yempahla ekrwada, ungcoliseko oluncinci ngexesha lemveliso, kwaye inokuphinda isetyenziswe emva kokuchithwa, ehlangabezana neemfuno zophuhliso oluzinzileyo. Ngelo xesha, iimpawu zayo zokusebenza ezizinzileyo zexesha elide zinciphisa iingozi zokusingqongileyo ezifana nokuvuza kwezinto ezibangelwa ngumonakalo wepayipi, ukubonelela ngesiqinisekiso sokuvelisa uhlaza kumashishini.
Ukusuka kuthutho lwemisila emigodini ukuya kuthutho lwe-asidi kunye ne-alkali kushishino lwemichiza, ukusuka kunyango lothuthu lwempukane kwishishini lamandla ukuya kuthutho oluludaka kushishino lwesinyithi, imibhobho enganyangekiyo ye-silicon carbide ngokuthe ngcembe ithatha indawo yemibhobho yemveli ngomsebenzi wayo "ongundoqo" kwaye ibe yeyona nto ithandwayo kwindawo yezothutho kushishino. Ayibonisi kuphela inkqubela phambili yetekhnoloji yezinto eziphathekayo, kodwa iphinda iqaqambise ingcamango yophuhliso lwamashishini afuna ukusebenza kakuhle, ukonga umbane, kunye nemveliso ehambelana nokusingqongileyo.
Kwixesha elizayo, kunye nokuphuculwa okuqhubekayo kobuchwepheshe, iibhobho ze-silicon carbide ezikwazi ukunxiba ziya kudlala indima kwiinkalo ezininzi, ukubonelela ngenkxaso ethembekileyo yokusebenza ngokufanelekileyo kwemveliso yemizi-mveliso kwaye ibe yinto ebalulekileyo ekukhuthazeni ukuphuhliswa kwemizi-mveliso ephezulu.
