I-Isostatic pressing graphite: into evelele emikhakheni eminingi

I-graphite ecindezelayo ye-Isostatickuyinto esebenza ngezinto eziningi edlala indima ebalulekile emikhakheni ehlukene.Ngezansi, sizonikeza isingeniso esiningiliziwe sokusetshenziswa okuhlukene kwe-graphite yokucindezela ye-isostatic emikhakheni eminingana emikhulu ukuze siqonde ukusetshenziswa kwayo okusabalele kanye nenani eliyinhloko embonini yesimanje.

 

1. Izicelo embonini yamandla enuzi

Ama-nuclear reactors angumongo wemboni yamandla enyukliya, adinga izinduku zokulawula ukuze zilungise inani lama-neutron ngesikhathi esifanele ukuze kulawulwe ukusabela kwenuzi.Emazingeni okushisa aphezulu apholile ngegesi, izinto ezisetshenziselwa ukwenza izinduku zokulawula zidinga ukuhlala zizinzile endaweni yokushisa ephezulu kanye nezindawo zokushiswa kwemisebe.I-Isostatic pressing graphite isiphenduke enye yezinto ezifanele zokulawula izinduku ngokuhlanganisa ikhabhoni ne-B4C ukwenza isilinda.Njengamanje, amazwe anjengeNingizimu Afrika kanye neShayina agqugquzela ucwaningo nokuthuthukiswa kweziphehlisi ezipholile ezinezinga lokushisa eliphezulu.Ukwengeza, emkhakheni wama-nuclear fusion reactor, njengohlelo lwe-International Thermonuclear Fusion Experimental Reactor (ITER) kanye nokuvuselelwa kwedivayisi ye-JT-60 yase-Japan namanye amaphrojekthi okuhlola we-reactor, i-isostatic graphite nayo idlala indima ebalulekile.

 

2. Isicelo emkhakheni wokukhipha imishini kagesi

Imishini yokukhipha ugesi iyindlela yokwenza imishini enembayo esetshenziswa kabanzi emkhakheni wokubunjwa kwensimbi nokunye.Kule nqubo, i-graphite nethusi zivame ukusetshenziswa njengezinto ze-electrode.Kodwa-ke, ama-electrode e-graphite adingekayo ukuze kukhishwe imishini adinga ukuhlangabezana nezimfuneko ezithile ezibalulekile, okuhlanganisa ukusetshenziswa kwamathuluzi okuphansi, isivinini somshini esisheshayo, ukuhwashala okuhle kwendawo, nokugwema ukuvela kwethiphu.Uma kuqhathaniswa nama-electrode ethusi, ama-electrode e-graphite anezinzuzo eziningi, njengokungasindi futhi kulula ukuphatha, kulula ukucutshungulwa, futhi athambekele kancane ekucindezelekeni nasekuguqukeni kokushisa.Yiqiniso, ama-electrode e-graphite nawo abhekana nezinselele ezithile, njengokuthambekela ekukhiqizeni uthuli nokuguga.Eminyakeni yamuva nje, ama-electrode e-graphite we-ultrafine particle discharge machining avele emakethe, okuhloswe ngawo ukunciphisa ukusetshenziswa kwe-graphite nokunciphisa ukukhishwa kwezinhlayiya ze-graphite ngesikhathi sokukhishwa kwemishini.Ukumakethwa kwalobu buchwepheshe kuzoncika ezingeni lobuchwepheshe bokukhiqiza lomkhiqizi.

 

3. Insimbi engasiyoni eqhubekayo

Ukubunjwa okuqhubekayo kwensimbi okungeyona ayoni sekuyindlela evamile yokukhiqiza ithusi elikhulu, ithusi, ithusi, ithusi elimhlophe neminye imikhiqizo.Kule nqubo, ikhwalithi ye-crystallizer idlala indima ebalulekile ezingeni lokufaneleka lomkhiqizo kanye nokufana kwesakhiwo senhlangano.I-Isostatic pressing graphite material isiphenduke inketho ekahle yokwenza amakristalu ngenxa yokuguquguquka kwayo okuhle kakhulu kokushisa, ukuzinza kwe-thermal, ukuzithambisa, ukulwa nokumanzisa, kanye nokungangenisi kwamakhemikhali.Lolu hlobo lwe-crystallizer ludlala indima ebalulekile enqubweni yokusakazwa eqhubekayo yezinsimbi ezingenayo insimbi, ukuthuthukisa ikhwalithi yokucwebezela kwensimbi nokulungiselela imikhiqizo yokuphonsa yekhwalithi ephezulu.

 

4. Izicelo kwezinye izinkambu

Ngokungeziwe embonini yamandla enyukliya, ukuchithwa kwemishini, kanye nokusakazwa okuqhubekayo kwensimbi okungeyona ayoni, i-isostatic pressing graphite iphinde isetshenziswe ekwenzeni isikhunta se-sintering samathuluzi edayimane nama-alloys aqinile, izingxenye zensimu ezishisayo zemishini yokudweba i-fiber optic wire (njenge izifudumezi, amasilinda okufakelwa, njll.), izakhi zensimu ezishisayo zezithando zokushisa ze-vacuum (njengama-heaters, amafreyimu anamafreyimu, njll.), kanye nezishintshisi zokushisa ze-graphite ezinembayo, izakhi zokuvala uphawu, izindandatho ze-piston, ama-bearings, ama-rocket nozzles, kanye ezinye izinkambu.

 

Kafushane, i-isostatic pressing graphite iwumsebenzi osebenzayo osetshenziswa kabanzi emikhakheni eyahlukene efana nemboni yamandla enuzi, ukukhishwa kwemishini, kanye nokusakazwa okuqhubekayo kwensimbi okungeyona ayoni.Ukusebenza kwayo okuhle nokuvumelana nezimo kuyenza ibe ngenye yezinto ezibalulekile emikhakheni eminingi yezimboni.Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nesidingo esikhulayo, amathuba okusetshenziswa kwe-isostatic pressing graphite azoba banzi, alethe amathuba amaningi nezinselelo ekuthuthukisweni kwezimboni ezihlukahlukene.
