Ithini inkqubo yemveliso ye-Aluminii i-ceramics enganyangekiyo?
1. Ukulungiswa kwePowder
I-aluminium oxide umgubo kumzi-mveliso ulungiselelwe izinto ze-powder ngokweemfuno ezahlukeneyo zemveliso kunye neenkqubo ezahlukeneyo zokubumba. Ubungakanani be-poder bungaphantsi kwe-1μm, ukuba ukwenziwa kweemveliso ze-Alumina ye-Alumina kwi-Aloumina kwi-99.99%, kodwa ikwafuna ukuba i-ultrafine igijimeza kwaye yenze ubungakanani be-surtrafine yokusasaza. Xa ipleyiti engaphikisiyo icinyiwe okanye inaliti ibunjwe, i-binder kunye neplastiki kufuneka ingeniswe kwi-powder, i-thermoplastic okanye i-thermotistic okanye i-thersistic edityaniswe ne-alder ye-Alomina iququzelele ukusebenza kwe-aluting.
Izinto zomgubo ezenziwe ngenkqubo yokucinezelwa eshushu azidingi ukongeza i-binder. Ukuba i-Semi-Ngokuzenzekelayo isetyenziselwe ukugqabhuka komzimba, ipowder ineemfuno zenkqubo ekhethekileyo, kwaye iyimfuneko ukusebenzisa i-spran yendlela yokunyanga umgubo kwaye iphucule ukugcwaliswa kwe-pollcec yodonga ekubunjweni. Ukongeza, ukuze kuncitshiswe ukungqubana phakathi komgubo kunye nodonga olunyibilikayo, kufuneka ukongeza i-1 ukuya kwi-2% ye-oyile, njenge-stearic acid kunye ne-binder Pva. Ukutsala oomatshini bokubumba, i-pider yokutshiza iyafuneka, apho kungeniswa khona i-polyvinyl utywala.
I-2. Indlela yokubumba
Iindlela zokwenza iimveliso ze-aluminic ze-aluminic zibandakanya ukucinezela ezomileyo, ukukhula, ukuphelelwa kwe-isostatic, ukucofa, ukucofa, ukucinezelwa kwesostatic kunye nokucinezelwa kwesostatic kunye nokucinezelwa kwesostatic. Kwiminyaka yakutshanje, ekhaya nakwamanye amazwe baqulunqe isithsaba sokucoca, ukuqiniseka ngokuthe ngqo kwinaliti, intshi yejeli yejeli yokubumba, inaliti yejeligigal Imilo eyahlukeneyo yemveliso, ubungakanani, iimilo ezintsonkothileyo kunye neemveliso ezichanekileyo zifuna iindlela ezahlukeneyo zokubumba. Intshayelelo yokwenziwa kwayo okuqhelekileyo:
◆ Indlela yokuGqibela: Ukubuyiswa okukhulayo yindlela yokubumba kwasekuqaleni esetyenziselwa i-Aluminics Ceramics. Ngenxa yokusetyenziswa kwe-gypsim ye-Gypsim, iindleko ziphantsi kwaye kulula ukwenza ubungakanani obukhulu kunye neenxalenye ezinzima. Eyona nto iphambili yokubumba okukhulayo kukulungiselela i-Alumna Slarry. Ngokwesiqhelo amanzi asetyenziswa njenge-flux ephakathi, kwaye emva koko iarhente ye-hagrumming kunye ne-binder yongezwa, emva koko irhasi ikhutshiwe, emva koko i-gesi ikhutshiwe ngasemva. Ngenxa yokufika kwamanzi ziintloko ze-capijecki ye-Plaster, i-slourry iqinisiwe ekubunjweni. Xa ipleyiti engaphili i-disnent ayinamsebenzi, i-slirry egqithileyo kufuneka ithululelwe xa i-slickry ivunyelwe kudonga olunzima lufikelela kubunzima obufunekayo. Ukuze unciphise i-shrinkage yomzimba, i-surrication yoxinzelelo ephezulu kufuneka isetyenziswe kangangoko kunokwenzeka.
◆ Cinezela ukubumba: I-Alumina Ceramic Lowork Itekhnoloji yokuBulda inomda wokufumana ubume obulula kunye nobubanzi obungaphakathi, obungaphezulu kwe-1mm, izinto ezingaphezulu kwe-4: 1 izinto. Iindlela ezibunjiweyo azinawo okanye i-bidirectial. Umatshini wokushicilela uneentlobo ezimbini zohlobo lwe-hydraulic kunye nohlobo lomatshini, olunokuba yindlela yokuseka ngokuzenzekelayo okanye ezenzekelayo. Olona xinzelelo luphezulu lwe-rasti yi-200MPA. Iziphumo zinokufikelela kwi-15 ~ 50 i-50 yeziqwenga ngomzuzu. Ngenxa yengcinezelo ye-iyunifomu ye-intermarm ye-hydraulic, ukuphakama kweenxalenye ezixineneyo kwahlukile xa ugcwalisa umgubo wahlukile. Ubungakanani boxinzelelo olwenziwe ngumatshini wokushicilela umatshini wokugcwaliswa komgubo, ekulula ukukhokelela kumahluko kwisayizi kwaye kuchaphazela umgangatho wemveliso.
Ke ngoko, ukusasazwa kwe-Poplermarments amasuntswana eposti yenkqubo eyomileyo kubaluleke kakhulu ekugcwaleni. Nokuba isixa sokuzalisa sichanekile okanye asinampembelelo enkulu kulawulo oluchanileyo lwe-Alumina ye-Alummic. I-Poiders Asunts engaphezulu kwe-60μm, phakathi kwe-60 ~ 200 Mesh inokufumana ezona ziphumo ziphezulu zokuhamba kwamahhala, ukufezekisa ezona zinto zinesiphumo sobunjineli.
I-onsorments yezinto eziphilayo kufuneka zongezwe kwi-Alumina Ceramic Slurry ukwenza umaleko wombane ophindwe kabini kumphezulu wamasuntswana etyibilikisi ukuze incitshiswe ngokungxama ngaphandle kokuhlala. Ukongeza, iibhendi ezinje nge-vinyl utywala, i-methyl seluplose, i-aminease amine kunye ne-polnacys efana ne-polyacybuslasside kwaye i-Gum Aractic yongezwa ukwenza umsebenzi ofanelekileyo wokutya.
3. Itekhnoloji yokudubula
Indlela yezobugcisa yokuphucula umzimba we-ceramic ye-granial kwaye yenze izinto ezomeleleyo ekubizwa ngokuba yini Indlela yokuqinisa kukususa i-vaid phakathi kwamasuntswana emzimbeni weBillet, susa inani elincinci lezinto eziphilayo zegesi kunye nokwenza amasuntswana akhule kwaye adibane nayo ukwenza izinto ezintsha.
Isixhobo sokufudumeza esisetyenziselwa ukudubula sesona siko lisetyenziswa kakhulu ngombane. Ukongeza kwi-themosfic yoxinzelelo lwe-quosmosfic, oko kukuthi, ukuqina okungakhathalelwanga, kukho i-sooning yoomoni eshushu kunye ne-Istatic eshushu. Nangona ishushu eqhubekayo ishushu inyusa iziphumo, izixhobo kunye neendleko zeflegi ziphezulu kakhulu, kwaye ubude bemveliso bunqunyelwe ngenxa yokufudumeza. I-SOSTATIC eshushu i-isostating isebenzisa ubushushu obuphezulu kunye negesi ephezulu njengoncedo loxinzelelo phakathi, kwaye inesibonelelo sokukhumbula iyunifomu kuyo yonke imikhombandlela, kwaye ilungele ukuthunyelwa kwemveliso entsokothileyo. Ngenxa yesakhiwo esilinganayo, iipropathi zezinto ezibonakalayo ezingama-30 ~ 50% ephezulu kunaleyo yokubanda kucinezela ukuthungwa kwesono. Yi-10 ~ 15% ephezulu kune-jikelele eshushu eshushu.
Ke ngoko, okwangoku, ezinye zexabiso eliphezulu longezwa iimveliso ze-Alwemina okanye iinxalenye ezikhethekileyo ezifunekayo ukuze zikhuseleke kuzwelonke, ezinjengeebhulori ze-ceramic, i-sublear i-subs, intsimi isebenzisa i-isostatic ye-isostating eshushu.
Ukongeza, kukho indlela ye-microwave yeyemithi, indlela ye-ARC ye-ARC Plasmang, ukusasazeka kokuzihlaziya.
4, ukugqiba kunye neenkqubo zokupakisha
Ezinye izixhobo kufuneka zigqitywe emva kokona. Iimveliso ezinokusetyenziswa njengoko amathambo afundwayo afuna indawo ephezulu, njengesipili, ukwandisa i-thambisa. Ngenxa yobunzima obukhulu bee-aluminic ze-aluminic, iipleyiti ezinganyangekiyo kufuneka zigqitywe ngamandla okugaya kunye nezitena zepolishi. Ezinje nge-sic, b4c okanye idayimane.
Ihlala isetyenziswa ukusuka kwi-coarse ukuya kwinyathelo lokugaya inyathelo ngenyathelo, umphezulu wokugqibela. Ngokubanzi inokusetyenziswa <1μm micron al23 powder okanye idayimani yedayimani yokugaya kunye nokuphola. Ukongeza, ukwenziwa kwe-laser kunye nokulungisa i-ultrasonic ukuqhubekeka kwe-Garinding kunye neendlela zokuphumelela zinokusetyenziswa. Ezinye iinxalenye ze-aluminica i-ceramic kufuneka zifakwe kwezinye izixhobo.
