Kwimveliso yemizi-mveliso, imibhobho ifana “nemithambo yegazi” ethwala izinto ezirhabaxa kakhulu ezifana nentsimbi, umgubo wamalahle, kunye nodaka. Ekuhambeni kwexesha, iindonga zangaphakathi zemibhobho eqhelekileyo ziyaguga lula kwaye ziqhekeke, zifuna ukutshintshwa rhoqo kwaye zinokuchaphazela imveliso ngenxa yokuvuza. Kule ndawo, izinto ezibizwa ngokuba"Umbhobho onganyangekiyo we-silicon carbide"Kwaba luncedo kakhulu. Kwakufana nokubeka “ivesti engangenisi mbumbulu” emjelweni, ube “yingcaphephe” ekulweni nokonakala kwezinto eziphathekayo.
Omnye umntu angabuza, yintoni i-silicon carbide? Enyanisweni, yinto engabonakaliyo eyenziwe ngokwenziwa enesakhiwo esiqinileyo. Umzekelo, udonga lwangaphakathi lombhobho oqhelekileyo lufana nomgangatho wesamente orhabaxa, kwaye njengoko izinto zihamba kuwo, zihlala "zikrwela" umhlaba; Udonga lwangaphakathi lwemibhobho ye-silicon carbide lufana neeslabs zelitye eliqinileyo elikhazimlisiweyo, olunokumelana okuncinci kunye nokuguguleka okuncinci xa izinto zihamba. Olu phawu luyenza ibe namandla ngakumbi ekugugulekeni kunemibhobho yentsimbi eqhelekileyo kunye nemibhobho yeseramikhi, kwaye xa isetyenziswa ekuhambiseni izinto eziguguleka kakhulu, ubomi bayo benkonzo bunokwandiswa amaxesha amaninzi.
Nangona kunjalo, i-silicon carbide ngokwayo ibuthathaka kwaye inokuqhekeka lula xa yenziwe ngokuthe ngqo ibe yimibhobho. Uninzi lwemibhobho yangoku engagugiyo ye-silicon carbide idibanisa izinto ze-silicon carbide kunye nemibhobho yesinyithi - nokuba ngokuncamathisela umaleko weethayile ze-silicon carbide ceramic eludongeni lwangaphakathi lombhobho wesinyithi, okanye ngokusebenzisa iinkqubo ezikhethekileyo zokuxuba umgubo we-silicon carbide kunye ne-adhesive, ukugubungela udonga lwangaphakathi lombhobho ukwenza umaleko onamandla ongagugiyo. Ngale ndlela, umbhobho unobunzima besinyithi, obungaguqukiyo okanye obuqhekekileyo lula, kunye nokumelana nokuguguleka kwe-silicon carbide, ukulinganisela ukusebenza kunye nokuqina.
Ukongeza ekungagugini, iipayipi ezinganyangekiyo ze-silicon carbide zikwanazo neengenelo zokungagugini kubushushu obuphezulu nobuphantsi kunye nokungagugini. Ezinye izinto zoshishino azigugi kakhulu nje kuphela, kodwa zinokuba neempawu ze-asidi okanye ze-alkaline. Iipayipi eziqhelekileyo ziguginiwa lula kukudibana kwexesha elide, ngelixa i-silicon carbide inokumelana kakhulu ne-asidi kunye ne-alkali; Nokuba ubushushu bezinto ezithuthwayo buyatshintshatshintsha, ukusebenza kwayo akuyi kuchaphazeleka kakhulu, kwaye iimeko zokusetyenziswa kwayo zibanzi kakhulu, ukusuka kwimigodi kunye namandla ukuya kumashishini eekhemikhali kunye ne-metallurgical, apho ubukho bayo bunokubonwa khona.
Kumashishini, ukusebenzisa imibhobho engagugiyo ye-silicon carbide akuthathi indawo yento enye kuphela, kodwa kunciphisa nokuphindaphindeka kokutshintshwa kwemibhobho, kunciphisa iindleko zokugcinwa kwexesha lokungasebenzi, kwaye kunciphisa iingozi zokhuseleko ezibangelwa kukuvuza kwezinto. Nangona utyalo-mali lwayo lokuqala luphezulu kunolo lwemibhobho eqhelekileyo, ekuhambeni kwexesha, eneneni lubiza kancinci.
Kule mihla, ngenxa yokwanda kwemfuno yokuqina kwezixhobo kunye nokhuseleko kwimveliso yemizi-mveliso, ukusetyenziswa kwemibhobho engagugiyo ye-silicon carbide kuya kuxhaphaka ngakumbi. Olu "phuculo lwemibhobho" olubonakala lungabalulekanga ngokwenene lufihla ubuchule bokutsha kwezinto zoshishino, okwenza inkqubo yemveliso ibe nozinzo kwaye isebenze kakuhle - le yipayipi engagugiyo ye-silicon carbide, "ingcali engagugiyo" ekhusela buthule "imithambo yegazi" yemizi-mveliso.
