Inkqubo yemveliso ye-aluminii
Ukulungiswa kwePowder
I-aluminium oxide umgubo kumzi-mveliso ulungiselelwe izinto ze-powder ngokweemfuno ezahlukeneyo zemveliso kunye neenkqubo ezahlukeneyo zokubumba. Ubungakanani be-powder ye-powder bungaphantsi kwe-1μm, ukuba ukwenziwa kweemveliso ze-alumina ceraical alumina ukongeza kubunyulu be-Aluminii kwi-99.99%, kodwa kufuneka kwenziwe i-ultrafine yokusasaza iyunifomu yokuhambisa iyunifomu. Xa ukupheliswa kwesithsaba okanye inaliti isetyenzisiwe, ii-binders kunye neeplastiki kufuneka zingeniswe kwi-powder, i-thermoplaspics ngokubanzi okanye i-resitis okanye i-resitins enomyinge we-10-30%. I-organic binder kufuneka idityaniswe kunye ne-Alomina Powder kwi-150-200 iqondo lobushushu ukulungiselela ukusebenza kobumba. 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, ukwenzela ukunciphisa ukungqubana phakathi komgubo kunye nodonga olunyibilikayo, kunyanzelekile ukuba bongeze i-1 ukuya kwi-2% ye-oyile, njenge-steric acid, kunye ne-binder Pva.
Ukutsala oomatshini bokubumba, i-pider yokutshiza iyafuneka, apho kungeniswa khona i-polyvinyl utywala. IZiko loPhando kwi-shanghai iphuhlise i-paraffin ye-paraffin yeparaffin njenge-binder ye-alcoring ye-al203 i-spran yokutshiza, enobuqhophololo olungileyo phantsi kokufudumeza. Umgubo emva kokutshiza kufuneka ube nolwelo oluhle, ukuxinana okuphezulu, kunye nokuhamba kweqondo lobushushu be-ferle. Ukuze ufumane ukuxinana okuphezulu kwento engenanto, ubungakanani be -unticle ubungakanani bulungile.
Indlela yokwenza
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:
I-1, i-aluminiing yomatshini wokuBumba: I-Aluminii Ceramic Lowork Itekhnoloji yokuBula inomda wokubonakala ngokulula kunye nobubanzi obungaphezulu kwe-1mm, izinto ezinobude obungaphezulu 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 lweendaba ubuninzi 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.
2, Indlela yokuBuyisela okuPhumeleleyo: Ukubumba okuPhumeleleyo 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. Ngokukhuseleka okukhula, ukuthambisa kakhulu kufuneka kuthululelwe xa i-slickry i-adrery iveliswe kudonga olunzima lufikelela kubunzima obufunekayo. Ukuze unciphise i-shrinkage yomzimba, i-surrication yoxinzelelo ephezulu kufuneka isetyenziswe kangangoko kunokwenzeka.
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.
