YINTONI EBALULEKILEYO KWIINGXAKI ZEXESHA LOKUFUNDA?

I-pores kwi-Copper Reducmations (kubandakanya ne-brass, i-bronze, i-bronze, imfuyo, njl njl. Ezi zilandelayo zizizathu ezikhethekileyo kunye nezisombululo:

1, Iindidi kunye neempawu ze-Stomata 1 yeempawu zepores: ezincinci, ezisasazeke, isetyhula okanye i-elliptical, ikwindawo yokuqinisa. Isizathu: Iigesi zinyibilikisiwe kulwelo lwe-Copper  

2. Iimpawu zepores ezisebenzayo: Iindonga ze-oxid okanye ezigudileyo, zihlala zivela okanye kufutshane nendawo yokuphoxeka. Isizathu: I-Copper i-Copperle i-Commally ye-chemings ngesanti esebunjiweyo, ihlambuluki okanye i-slag ukuvelisa igesi (njenge-CO ₂, i-CO).  

I-3. Iimpawu ze-pores: ubume obungaqhelekanga, ihlala ihamba kunye ne-Slag iqukuthezi, isasazwe kwicala lokuhamba kwentsimbi. Isizathu: Ngexesha lenkqubo yokugada, irhasi itsalwa kwinyithi etyhidiweyo (efana nokuthulula okungapheliyo).  

2, Uhlalutyo oluphambili

1. I-Hydrogen ngexesha lenkqubo yokunyibilikisa (into ephambili): Ulwelo lwe-Copper luthambe kakhulu ekufumaneni igesi ye-hydrogen kwiqondo lobushushu (i-tin ye-hydrogen), kunye ne-slobroning ye-hydrogen yehlisa ubukhali, i-pores. Umthombo: Isixhobo sezothando singamafutha, ioyile, okanye iqulathe imeko yezinto eziphilayo (ezinje nge-oyile enokuphinda isebenze i-oyile kunye negrisi). Indawo yokunyibilika inomswakama ophezulu (njengokungakhathali ngexesha lemvula). Ukudibana okungapheliyo (isiqithi segesi, isithando segesi, i-COKE ivelisa i-vapor yamanzi).  

I-2. I-Deajidation engapheliyo iphumela kwi-oxidation ye-oxider i-for cu c O, enika i-Hydrogen: cu ₂ ₂ ₂ * * * Ihlala ibonwa kwi: phosphor bronze (ifuna i-phosphorus deoximidotion), uBrass (akasebenzi i-zinc deiling deilation).  

3. Uyilo olungalunganga lwenkqubo yokuthulula, ukuphakama kwesango, okanye ukunganeli indawo yecandelo lecandelo le-sprue, ekhokelela ekuhambeni kwentsimbi ye-molten kunye nokufakwa komoya. Ukuphakama okungapheliyo okanye ukuphelisa amajelo okuthintela igesi ukubaleka.  

I-4. Intlabathi / Iingxaki zobumba: I-moya engekho mthethweni yesanti yesanti (ezinje ngempangelo oluphezulu kunye nokungabikho kwentlabathi yesodium). Xa isanti ye-resin okanye isanti yeoyile iphoswe, i-binder ikhupha isixa esikhulu segesi (njenge-H ₂ kunye ne-H ₂ ₄ iveliswa yi-furan relin). Xa uphosa iimbumbulu zensimbi, ukubumba akunayo i-groovesm grooves okanye ukungqubana kakhulu.  

I-5. Inkqubo engalunganga yokusebenza: Iqondo lokuhlala liphezulu kakhulu (i-Exdrogen ye-hydrogen) okanye iphantsi kakhulu (irhasi ayinakho ukuntywila ngexesha). Ayivumelekanga ngokupheleleyo ukuba ihlawulwe (igalelwe ngaphandle kokungenisa ulwelo lobhedu). Isisombululo

I-1. Ukunyibilikisa ukulawulwa kokungafihli Ubhedu: Sebenzisa ifuthe "lokuzila" kwe-zinc ukuze ususe i-hydrogen kwaye ulawule ubushushu bokunyibilika (uBrass ≤ 1100 ℃). Izinto zokuthambisa zezomhlaba: Inkunkuma yobhedu kufuneka ihlawulwe ukususa amabala e-oyile, kwaye izixhobo zokutsala kunye nezixhobo ziya kufuneka zinyibilikiswe. Ikhuselo Lukhuseleko: gubungela ulwelo lobhedu nge-charcoal okanye i-slag yeglasi ngexesha lokunyibilika ukwahlula umphunga wamanzi.  

2. Ukuphuculwa kwenkqubo yokuthulula, yamkela inaliti ephantsi okanye inkqubo yokuthulula inyathelo lokunciphisa isiphithiphithi. Ukonyusa umyinge wendawo enqamlezayo yendawo eguqukayo kunye neembaleki zangaphakathi (E.G. 1: 2: 1.5) kwaye unciphise isantya sokuhamba. Misela iingxowa zengqokelela ye-SLAG kunye nokuphelisa ukuphelisa (ngakumbi kwiindawo ezinobunzima kunye neendawo ezinkulu).  

3. Ukuphoswa kwesanti / ukuphuculwa kwesanti / ukuphuculwa kwesanti Intsimbi yokuphosa i-rold: i-mold ixhotywe i-groove evuthayo (ubunzulu 0.1 ~ 0.3mm) kwaye idityaniswe ngepeyinti ye-zinc. ISAPRIN SAND: Ukunciphisa isixa se-resin esongeziweyo okanye ukutshintshela kwi-nitrogen ephantsi.  

4. Qhoboshela inkqubo yokuhlengahlengiswa kweqondo lokulinganisa: 1200 ~ 1250 ℃ Ukuze ubhedu, i-980 ~ 1050 ℃ yobhedu, i-1100 ~ 1180 ℃ ngobhedu. Ngokuthe ngcembe upholile emva kokuthulula (njengokugubungela nge-inshurensi yesanti) yokwandisa ixesha lokukhutshwa kwerhasi.  

I-5. Imilinganiselo yokuncedisa yokufumana i-melt: sebenzisa i-vacuum yovavanyo lokuqiniswa kokujonga umxholo wegesi wolawulo lwegesi. Ukulungiswa kweposi: I-Isostatic ye-isostatic (i-hip) yenziwa kwizifundo eziphambili ukuphelisa ukutyeba ngaphakathi. I-4, imeko yesiqhelo yobhedu (CU ZN) i-Porossity: I-Zinc Homatilic ikhokelela kwi-SIFRING "ye-biiling" ye-biiling "kunye neShdrogen" ye-HYDRING "kunye ne-SNDROGY HYHROGRY HYIRD (≤ 40%), kwaye kufuneka komelezwe xa kunyibilika. I-tin bronze  

Ngokuphanda ngokucwangcisiweyo iinkqubo ezifana nokunyibilika, ukubumba, kunye nokugalela, kunokwenzeka ukuba zinciphise iziphene ze-piressity kwi-COORCHE. Ukuba ingxaki iyaqhubeka, kuyacetyiswa ukuba uqhubeke nokufumana umthombo wegesi ngohlalutyo lwe-nimellographic yohlalutyo lwe-pore
