I-Isostatic pressing graphite: imathiriyeli ebalaseleyo kwiindawo ezininzi

I-Isostatic icinezela igraphiteyimathiriyeli enemisebenzi emininzi edlala indima ebalulekileyo kwiinkalo ezahlukeneyo. Apha ngezantsi, siza kubonelela ngentshayelelo eneenkcukacha kusetyenziso olwahlukileyo lwe-isostatic yokucinezela igraphite kwiinkalo ezininzi eziphambili ukuqonda ukusetyenziswa kwayo ngokubanzi kunye nexabiso eliphambili kushishino lwanamhlanje.

 

1. Izicelo kushishino lwamandla enyukliya

Iireactors zeNyukliya zingundoqo kushishino lwamandla enyukliya, zifuna iintonga zolawulo ukunyenyisa inani leenyutroni ngexesha elifanelekileyo ukulawula ukusabela kwenyukliya. Kwiqondo eliphezulu lobushushu be-gas-cooled reactors, izinto ezisetyenziselwa ukwenza iintonga zokulawula kufuneka zihlale zizinzile kwiqondo lokushisa eliphezulu kunye neendawo zokukhanya. I-Isostatic pressing graphite ibe yenye yezinto ezifanelekileyo zokulawula iintonga ngokudibanisa i-carbon kunye ne-B4C ukwenza i-cylinder. Okwangoku, amazwe afana noMzantsi Afrika neTshayina akhuthalele ukukhuthaza uphando nophuhliso lwezixhobo zorhwebo ezipholileyo ngegesi. Ukongeza, kummandla weereactor zokudityaniswa kwenyukliya, njengenkqubo ye-International Thermonuclear Fusion Experimental Reactor (ITER) kunye nokulungiswa kwesixhobo se-JT-60 saseJapan kunye nezinye iiprojekthi zovavanyo lwe-reactor, isostatic graphite nayo idlala indima ebalulekileyo.

 

2. Isicelo kwintsimi yokukhutshwa kombane

Ukukhutshwa kombane kuyindlela ephezulu yokuchaneka esetyenziswa ngokubanzi kwintsimi yokubumba isinyithi kunye nolunye umatshini. Kule nkqubo, igraphite kunye nobhedu zisetyenziswa ngokuqhelekileyo njengezinto ze-electrode. Nangona kunjalo, ii-electrode zegraphite ezifunekayo kumatshini wokukhupha kufuneka zihlangabezane neemfuno eziphambili, kubandakanya ukusetyenziswa kwesixhobo esisezantsi, isantya somatshini okhawulezayo, uburhabaxa obuhle bomphezulu, kunye nokuphepha ukuvela kweengcebiso. Xa kuthelekiswa nee-electrode zobhedu, ii-electrode zegraphite zineenzuzo ezininzi, ezifana nokuba zikhaphukhaphu kwaye kulula ukuzibamba, kulula ukusetyenzwa, kwaye ziphantsi koxinzelelo kunye ne-thermal deformation. Ewe kunjalo, ii-electrode zegraphite zikwajongene nemiceli mngeni ethile, njengokutyekela ekuveliseni uthuli kunye nokunxiba. Kwiminyaka yakutshanje, i-electrode ye-graphite ye-ultrafine particle discharge machining iye yavela kwimarike, ijolise ekunciphiseni ukusetyenziswa kwegraphite kunye nokunciphisa i-detachment ye-graphite particles ngexesha lokukhutshwa kwe-machining. Ukuthengiswa kobu buchwepheshe kuya kuxhomekeka kwinqanaba leteknoloji yemveliso yomenzi.

 

3. Isinyithi esingenantsimbi esiqhubekayo

Intsimbi engapheliyo yokuphosa iye yaba yindlela eqhelekileyo yokuvelisa ubhedu olukhulu, ubhedu, ubhedu, ubhedu olumhlophe kunye nezinye iimveliso. Kule nkqubo, umgangatho wekristali udlala indima ebalulekileyo kwizinga lokufaneleka kwemveliso kunye nokufana kwesakhiwo sombutho. I-Isostatic icinezela imathiriyeli yegraphite ibe lolona khetho lufanelekileyo lokwenza iikristali ngenxa yokuhanjiswa kwayo okugqwesileyo kwe-thermal, ukuzinza kwe-thermal, ukuzithambisa, ukumanzisa okuchasayo, kunye nokungangeni kwemichiza. Olu hlobo lwe-crystallizer ludlala indima ebalulekileyo kwinkqubo eqhubekayo yokuphosa isinyithi esingenawo i-ferrous, ukuphucula umgangatho we-crystallization yesinyithi kunye nokulungiselela iimveliso zokuphosa ezikumgangatho ophezulu.

 

4. Izicelo kwezinye iindawo

Ukongeza kwishishini lamandla enyukliya, ukukhutshwa kwe-machining, kunye nokuphosa okuqhubekayo kwesinyithi, i-isostatic pressing graphite iphinda isetyenziswe ekwenzeni i-sintering mold yezixhobo zedayimani kunye ne-alloys eqinile, i-thermal field components for fibre optic wire drawing machines (ezifana ne izifudumezi, iisilinda zokugquma, njl.njl.), izinto ezishushu kwibala lokufunxa ubushushu (ezifana nezifudumezi, iifreyimu ezithwalayo, njl.njl.), kunye nokuchaneka kokutshintshisa ubushushu begraphite, izixhobo zokutywina ngoomatshini, amakhonkco episton, iibheringi, imilomo yerokhethi, kunye eminye imimandla.

 

Isishwankathelo, isostatic pressing graphite yimathiriyeli esebenzayo esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana neshishini lamandla enyukliya, ukukhupha iimachining, kunye nesinyithi esingeyontsimbi eqhubekayo. Ukusebenza kwayo okugqwesileyo kunye nokuguquguquka kuyenza ibe yenye yezinto eziyimfuneko kwiindawo ezininzi zoshishino. Ngophuhliso oluqhubekayo lwetekhnoloji kunye nemfuno eyandayo, amathuba okusetyenziswa kwegraphite ye-isostatic yokucinezela iya kuba banzi, izise amathuba amaninzi kunye nemingeni kuphuhliso lwamashishini ahlukeneyo.
