Kwiimeko zeefektri, ezemigodi, okanye ezothutho lombane, kukho uhlobo lombhobho "ongaziwayo" unyaka wonke kodwa uthwala uxanduva olunzima - bahlala bethutha izixhobo ezinezinto ezinamandla zokukrala ezifana nesanti, udaka, umgubo wamalahle, njl.njl. Iipayipi eziqhelekileyo zinokuguguleka ngexesha elifutshane, nto leyo engachaphazeli kuphela ukusebenza kakuhle kwemveliso kodwa ikwabeka neengozi zokhuseleko.imibhobho engagugiyo ye-silicon carbidengokuchanekileyo kukusombulula le ngxaki yemizi-mveliso, ibe ngumlindi "oqinileyo" kwiindawo ezinzima zothutho.
Yintoni umbhobho onganyangekiyo we-silicon carbide?
Ngamafutshane, iipayipi ezingagugiyo ze-silicon carbide ziipayipi zothutho ezenziwe ngokudibanisa i-silicon carbide njengezinto ezingundoqo ezingagugiyo kunye neepayipi zesinyithi (ezifana neepayipi zentsimbi) ngeenkqubo ezikhethekileyo.
Omnye umntu angabuza, yintoni i-silicon carbide? Yinto engeyiyo isinyithi eyenziwe ngokwenziwa ngobuchule enobunzima obuphezulu kakhulu, ilandela idayimani kuphela. Iisandpaper ezininzi kunye namavili okugaya esiwabonayo kubomi bemihla ngemihla zenziwe nge-silicon carbide. Ukusebenzisa ingcali enjalo 'engagugiyo' ukwenza ulwelo lwangaphakathi lwemibhobho kunokubangela ukuba iguge kakhulu.
Xa kuthelekiswa nemibhobho yentsimbi eqhelekileyo yendabuko kunye nemibhobho yamatye aqingqiweyo, inzuzo ephambili yemibhobho engagugiyo ye-silicon carbide ilele "kukulungiswa kwangaphakathi nangaphandle": umaleko wangaphakathi we-silicon carbide unoxanduva lokumelana nokuguguleka kunye nokuguguleka kwesixhobo, ngelixa umaleko wangaphandle wesinyithi uqinisekisa amandla apheleleyo kunye namandla okucinezelwa kombhobho. Ukudibana kwezi zimbini akusombululi nje kuphela ingxaki yokuguguleka, kodwa kukwaqwalasela ukhuseleko kunye nokuthembeka kokusetyenziswa kwimizi-mveliso.
Kutheni ikwazi 'ukumelana' neemeko ezinzima?
Ukuqina kwemibhobho engagugiyo ye-silicon carbide kuvela ikakhulu kwiimpawu zezinto ze-silicon carbide ngokwazo:
Ukumelana nokuguguleka okunamandla kakhulu: Njengoko bekutshiwo ngaphambili, i-silicon carbide inobunzima obuphezulu kakhulu, kwaye ukuguguleka komphezulu wayo kuhamba kancinci xa ijongene nokuguguleka kwexesha elide okuvela kwi-granular media efana ne-slurry kunye nesanti. Xa kuthelekiswa nemibhobho yentsimbi eqhelekileyo, ubomi bayo benkonzo bunokwandiswa amaxesha amaninzi okanye ngaphezulu kweshumi, nto leyo enciphisa kakhulu ukuphindaphindeka kunye neendleko zokutshintshwa kwemibhobho.
Ukumelana nobushushu obuphezulu nobuphantsi kunye nokumelana nokugqwala: Ukongeza ekungagugini, i-silicon carbide inokukwazi ukuziqhelanisa nobushushu obahlukeneyo, kwaye ingasebenza ngokuzinzileyo kwiindawo eziqala kwi-minus ten of degrees Celsius ukuya kwi-minus of degrees Celsius. Kwangaxeshanye, ikwanokumelana okuhle ne-corrosive media efana ne-asidi kunye ne-alkali, nto leyo eyenza ukuba ibe “nobuchule” kwiimeko zothutho ezinzima kumashishini afana neekhemikhali kunye ne-metallurgical.
Ukusebenza kakuhle kokuhambisa: Ngenxa yomphezulu ogudileyo we-silicon carbide lining, ukumelana kwesixhobo esihambayo kumbhobho kuphantsi, okwenza ukuba ungavaleki lula. Oku akuqinisekisi nje kuphela ukusebenza kakuhle kokuthutha, kodwa kunciphisa nexesha lokungasebenzi elibangelwa kukucocwa kwemibhobho.
Ibonisa phi izakhono zayo?
Nangona ivakala ngathi “yeyobuchwephesha”, ukusetyenziswa kwemibhobho engagugiyo ye-silicon carbide kusondele kakhulu kwimveliso yethu kunye nobomi bethu:
Kwimizi-mveliso yemigodi neyesinyithi, isetyenziselwa ukuthutha udaka lweminerali oluvela kwimigodi kunye nentsalela yenkunkuma evela ekunyibilikiseni, kwaye ichaphazeleka kukuguguleka okukhulu okuvela kwimithombo ye-particle enoxinzelelo oluphezulu;
Kwishishini lamandla, ngumbhobho obalulekileyo wokuthutha umgubo wamalahle kwizikhululo zamandla ezishushu, ukuqinisekisa ukunikezelwa okuzinzileyo kwepetroli yebhoyila;
Kwimizi-mveliso yezinto zokwakha kunye neekhemikhali, inokuthutha izinto zesamente, izinto zekhemikhali, njl.njl., ukuze ikwazi ukumelana nokuguguleka kunye nokugqwala okuncinci kwezixhobo ezahlukeneyo.
Kunokuthiwa nakweyiphi na intsimi yemizi-mveliso efuna ukuthuthwa kweendaba ezinokumelana nokuguguleka okunamandla kunye neemeko zokusebenza ezinzima, ubukho bemibhobho engagugulekiyo ye-silicon carbide bunokubonwa. Ibonelela ngeziqinisekiso ezibalulekileyo zokusebenza okuqhubekayo nokusebenza kakuhle kwemveliso yemizi-mveliso kunye nokusebenza kwayo "okuqinileyo", kwaye ikwayeyona nto ibalulekileyo kwiinkqubo zanamhlanje zokuhambisa izinto zoshishino.
