Ukusetyenziswa kwe-graphite ecocekileyo kakhulu: Umgubo we-Graphite. Kutheni umgubo we-graphite uthandwa kangaka? Kulindeleke ukuba imakethi yasekhaya yee-heater ze-graphite ibe ntle. Kutheni ii-heater ze-graphite zithandwa kakhulu ngabantu? Enyanisweni, isizathu sokuba ithandwa kakhulu ngabantu asinakwahlulwa kwiingenelo zayo. Ngoku, makhe sijonge iingenelo ezithile ze-heater ye-graphite kunye!
1. Isusa ngokupheleleyo i-oxidation kunye ne-decarburization kumphezulu we-workpiece ngexesha lenkqubo yokufudumeza, kwaye inokufumana umphezulu ococekileyo ngaphandle komaleko owonakeleyo. Oku kubaluleke kakhulu ekuphuculeni ukusebenza kokusika kwezo zixhobo ezigaya icala elinye kuphela ngexesha lokugaya (ezifana nee-twist drills apho umaleko we-decarburization kumphezulu we-groove uvezwe ngqo kumphetho wokusika emva kokugaya).
2. Ayibangeli ungcoliseko kwindalo esingqongileyo kwaye ayifuni unyango lwenkunkuma emithathu.
3. Inezinga eliphezulu le-mechatronics. Ngokusekelwe ekuphuculweni kokulinganiswa kobushushu kunye nokuchaneka kolawulo, ukuhamba kwezinto zokusebenza, ukulungiswa koxinzelelo lomoya, ukulungiswa kwamandla, njl. konke kunokuhlelwa kwangaphambili kwaye kusetwe, kwaye ukucima kunye nokunciphisa kungenziwa inyathelo ngenyathelo.
4. Ukusetyenziswa kwamandla kuphantsi kakhulu kunee-oven zetyuwa. Igumbi lokufudumeza le-graphite heater lanamhlanje lixhotyiswe ngeendonga zokukhusela kunye nezithintelo ezenziwe ngezinto zokukhusela ezikumgangatho ophezulu, ezinokugxininisa kakhulu amandla okufudumeza ombane ngaphakathi kwigumbi lokufudumeza, nto leyo efezekisa iziphumo ezimangalisayo zokonga amandla.
5. Ukuchaneka kokulinganisa nokubeka iliso ubushushu besithando kuphuculwe kakhulu. Ixabiso elibonisa i-thermocouple lifikelela ku-± ubushushu besithando1.5°c. Nangona kunjalo, umahluko wobushushu phakathi kwamacandelo ahlukeneyo enani elikhulu lezinto zokusebenza ezikwisithando mkhulu kakhulu. Ukuba ukujikeleza ngenkani kwegesi engaqhelekanga kwamkelwa, umahluko wobushushu usenokulawulwa ngaphakathi kwe-±5°c.
Ukukhupha igesi yimeko yokuphuma kancinci kwegesi kwi-graphite heater kwaye yeyona ngxaki ibalulekileyo ekusebenzeni kwe-graphite heater. Iileya zemolekyuli ezenziwe kukuqokelelwa kweegesi kunye nolwelo zinokunamathela kumphezulu wayo nayiphi na into eqinileyo. Ngenxa yokuncipha kancinci koxinzelelo, ezi leya zemolekyuli ziya kuphuma kancinci kancinci kuba amandla ezi ndawo angaphantsi kwalawo akhutshwa yi-graphite heater. I-nitrogen, izinyibilikisi eziguquguqukayo kunye neegesi ezingenayo zinesantya sokukhupha igesi ngokukhawuleza. Ioyile kunye nomphunga wamanzi ziya kuqhubeka zinamathela kumphezulu kwaye aziyi kuphuma de kube ziiyure ezimbalwa emva koko. Izinto ezinemingxuma, amasuntswana othuli kunye nezinye izinto zendalo ziya kwandisa indawo yomphezulu, ngoko ke kunokwenzeka ukuba kubekho ukukhupha igesi ngakumbi. Ukukhanya kunye nobushushu kuya kubonelela ngamandla aneleyo okwenza iimolekyuli ezifunxayo zisuke kumphezulu. Xa ubushushu besithando bunyuka, bunokukhulula iimolekyuli ezinamathele kumphezulu kumaqondo obushushu aphantsi. Ke ngoko, njengoko ubushushu besithando bunyuka, isiganeko sokukhupha igesi siya kunyuka kancinci.
Ulwakhiwo, ulawulo lobushushu, inkqubo yokufudumeza kunye nomoya ongaphakathi kwesithando somlilo se-graphite heater konke oku kuya kuchaphazela ngokuthe ngqo umgangatho wemveliso emva kokuveliswa kwesithando somlilo se-graphite. Kwisithando somlilo sokufudumeza esenziwe nge-forging, ukunyusa ubushushu besinyithi kunokunciphisa ukumelana nokunyibilika, kodwa amaqondo obushushu aphezulu kakhulu anokubangela i-oxidation yeenkozo okanye ukutsha kakhulu, okuchaphazela kakhulu umgangatho wemveliso ngaphakathi kwesithando somlilo se-graphite. Ngexesha lenkqubo yokunyanga ubushushu, ukuba intsimbi ifudunyezwa ukuya kwinqanaba elithile ngaphezu kobushushu obubalulekileyo ize ipholiswe ngequbuliso nge-arhente yokupholisa, ubunzima kunye namandla entsimbi anokonyuswa. Ukuba intsimbi ifudunyezwa ukuya kwinqanaba elithile ngaphantsi kobushushu obubalulekileyo ize ipholiswe kancinci, inokwenza intsimbi iqine ngakumbi.
Ukuze kufunyanwe izinto zokusebenza ezinemiphezulu egudileyo kunye nobukhulu obuchanekileyo, okanye ukunciphisa i-metal oxidation ngenjongo yokukhusela ii-molds kunye nokunciphisa izibonelelo zomatshini, ii-furnace ezahlukeneyo zokufudumeza ezine-low oxidation kunye ne-non-oxidation zingasetyenziswa. Kwi-furnace evulekileyo ene-oxidation encinci okanye engena-oxidation, ukutsha okungaphelelanga kwepetroli kuvelisa igesi enciphisayo. Ukufudumeza i-workpiece ekuyo kunokunciphisa izinga lokulahleka kokutsha kwe-oxidation ukuya ngaphantsi kwe-0.6%. I-graphite ecocekileyo kakhulu ibhekisa kumgubo we-graphite onomxholo we-carbon ongaphezulu kwe-99.9%. Le graphite ecocekileyo kakhulu enomxholo we-carbon ephezulu inombane oqhuba kakuhle, iipropati zokuthambisa, ukumelana nobushushu obuphezulu, ukumelana nokuguguleka, njl. I-graphite ecocekileyo kakhulu inomgangatho olungileyo kwaye inokucutshungulwa ibe zizinto ezahlukeneyo zokuhambisa, njl.
I-graphite ecocekileyo kakhulu inezicelo ezibalulekileyo kwicandelo lemveliso yemizi-mveliso. Isetyenziswa kumashishini afana nokuqhuba umbane, ukuthambisa, kunye ne-metallurgy. Ngexesha lokuveliswa kwe-graphite ecocekileyo kakhulu, umxholo wokungcola kufuneka ulawulwe ngokungqongqo kwizinto eziluhlaza, kwaye kufuneka kukhethwe izinto eziluhlaza ezinomlotha ophantsi. Ngaphezu koko, kufuneka kwenziwe imizamo yokuthintela ukongezwa kokungcola kangangoko kunokwenzeka ngexesha lenkqubo yemveliso. Nangona kunjalo, ukunciphisa ukungcola ukuya kwinqanaba elifunekayo kwenzeka kakhulu kwinkqubo ye-graphitization. I-Graphitization yenzeka kubushushu obuphezulu, kwaye ii-oxide ezininzi zezinto ezingcolileyo ziya kubola kwaye ziphele kubushushu obuphezulu. Okukhona ubushushu be-graphitization buphezulu, kokukhona ukungcola okuninzi kukhutshwa, kwaye kokukhona ubunyulu beemveliso ze-graphite ecocekileyo kakhulu eziveliswayo. Ukusetyenziswa kwe-graphite ecocekileyo kakhulu kusebenzisa ithuba lokuqhuba kwayo umbane okugqwesileyo, ukusebenza kokuthambisa, ukumelana nobushushu obuphezulu, njl.
Isizathu sokuba i-graphite ecocekileyo kakhulu ibe nobunyulu obuphezulu kwaye incinci ingcoliseko konke oku kuxhomekeke kwinkqubo yokuvelisa egqibeleleyo kunye nezixhobo. Umxholo wokungcola ungaphantsi kwe-0.05%. Iimveliso zethu ze-colloidal graphite, i-nano-graphite, i-high-purity graphite powder kunye nezinye iimveliso ze-graphite powder zisetyenziswa kakhulu kumashishini eekhemikhali, i-petroleum kunye ne-lubrication. I-graphite powder ecocekileyo kakhulu isetyenziswa ekucutshungulweni nasekuvelisweni kwezinto zombane ezifudumezayo, ii-structural casting molds, ii-metal crucibles ezicocekileyo kakhulu zokunyibilikisa, ii-graphite crucibles ezicocekileyo kakhulu, izixhobo ze-semiconductor, njl.njl.
