Alumina High isitena edityanisiweyo
Izinto eziluncedo Product: refractoriness eliphezulu, nokumelana olomeleleyo acid kunye nealkali zealgine, lobushushu eliphezulu amandla ngoomatshini, amandla aphezulu banxibe ukuxhathisa, ukuxobuka ukuxhathisa, ukumelana ubushushu kukothuka.
Ingcaciso yeMveliso
Izitena ezidityanisiweyo zealuminium Isitena esenziwe ngealuminiyam ephezulu sakhiwe ngesakhiwo esimaleko, esenziwe ngumaleko osebenzayo kunye nongqameko lobushushu. Isitena esidityanisiweyo sisakhiwo esimeyile esenziwe ngumaleko osebenzayo kunye nobushushu bokugquma ubushushu, kwaye sinesiphumo esihle sokumelana nomlilo kunye nefuthe lobushushu. Umaleko osebenzayo kunye nobushushu obugqume ubushushu buhlulwe ngokwahlukeneyo kwaye buxutywe ngexesha lokulungiselela, emva koko babumba badubula kunye. Umaleko osebenzayo wezitena ezidityanisiweyo unamandla okomelela ngokudibanisa ubushushu. Umaleko osebenzayo unokumelana neqondo lobushushu eliphezulu, ukumelana ne-asidi kunye ne-alkali, ukumelana ne-abrasion, amandla aphezulu, uzinzo olomeleleyo lokukhwankqiswa kobushushu, ukusebenza kakuhle kobushushu bokugquma kunye namandla obushushu bokugquma ubushushu. phezulu. Isitena esidityanisiweyo sinokuhlangabezana neemfuno zobugcisa kunye nokusetyenziswa kwesithando somlilo, sinokuqonda ukonga umbane kunye nokunciphisa ukusetyenziswa, kunye nokwandisa ubomi benkonzo yeziko lokujikeleza. Indlela yokulungiselela yenzululwazi kwaye iyavakala, ilula kwaye kulula ukuyiphumeza, kwaye ilungele ibhanti lokudubula kunye nebhanti lokucoca ulwelo olukhulu lweziko lokujikeleza. Ukongeza, iimveliso zodidi oluphezulu lwealuminium zisetyenziswa ngokubanzi kumashishini ahlukeneyo anje ngombane, isinyithi, isinyithi esingenantsimbi, petrochemicals, iglasi, isamente kunye nezinto zokwakha.
Inkcazo yezitena zealuminium eziphezulu:
1. Iimpawu kunye nokusetyenziswa:
It has refractoriness eliphezulu, nokumelana olomeleleyo acid kunye nealkali zeBelg, kunye namandla aphezulu ngoomatshini kwiqondo lobushushu eliphezulu, ngoko ke lisetyenziswa kakhulu kushishino metallurgical kunye nezinye zomlilo. Isetyenziselwa ubukhulu becala ulwelwesi lwee-kilns ezahlukeneyo ezishushu ezinje ngezitovu zombane, iivenkile zokuqhushumba, izitovu zokudubula ezishushu, iileli, imigqomo yesinyithi, iinqwelo zentsimbi, iilenki zesamente, iitiles zeglasi, njl. , isamente kunye namanye amashishini.
2. Ukucaciswa kwemveliso: umgangatho, oqhelekileyo kunye nobume obukhethekileyo, izitena ezimile ngokukodwa kunye nemilo ekhethekileyo.
3. Izitena ezitsalwayo zizinto ezikhutshiweyo ezinemilo ethile nobungakanani. Izitena ezibonakalisayo zinokuzinza okuhle kwe-thermal kwaye kufanelekile ukuba kushushu izitovu, iindlela ezahlukeneyo zokubilisa amanzi, iiflaya, amagumbi okutshaya, njl njl. kwaye nangokunjalo. Izitena ezibonakalisayo zihlala zahlulwe zaziindidi ezimbini, ezokuphinda zimiswe ezingafunekiyo kunye neefreyiki ezibunjiweyo. Izinto ezingafunekiyo ezingafunekiyo: ikwabizwa ngokuba yinto enokuphoswa, ngumgubo oxutywe nomgubo odityaniswe ngokudibeneyo okanye ngokudibeneyo kunye nokubopha enye okanye nangaphezulu. Xa isetyenziswa, ixutywe nolwelo olunye okanye nangaphezulu kwaye ixutywe ngokulinganayo. Fundisa ukuhamba ngamandla. Imilo yezinto ezilahlayo: ezenziwe ngezitena ezibonakalisayo, ukumila kwayo kunemithetho esemgangathweni, kwaye inokusetyenzwa okwethutyana ngokweemfuno xa kusakhiwa naxa kusikwa.
