Garaafka riixaya ee isostatic: walax aad u wanaagsan oo dhinacyo badan ah

Garaafka riixaya ee isostaticwaa maaddo shaqo badan oo door muhiim ah ka ciyaara dhinacyo kala duwan.Hoosta, waxaan ku siin doonaa horudhac faahfaahsan oo ku saabsan isticmaalka kala duwan ee istatic pressing graphite ee dhowr goobood oo waaweyn si loo fahmo codsigeeda baahsan iyo qiimaha muhiimka ah ee warshadaha casriga ah.

 

1. Codsiyada warshadaha tamarta nukliyeerka

Nuclear reactors waa xudunta u ah warshadaha tamarta nukliyeerka, una baahan ulaha kantaroolka si ay u hagaajiyaan tirada neutron-yada wakhtiga saxda ah si loo xakameeyo falcelinta nukliyeerka.Heerkul sare oo gaas qaboojiyeyaal ah, alaabta loo isticmaalo samaynta ulaha xakamaynta waxay u baahan yihiin inay ku xasilaan heerkulka sare iyo jawiga sunta.Garaafiga istaatiga ah ee riixaya wuxuu noqday mid ka mid ah qalabka ugu habboon ee ulaha xakamaynta iyadoo la isku darayo kaarboon iyo B4C si loo sameeyo dhululubo.Waqtigan xaadirka ah, wadamada sida Koonfur Afrika iyo Shiinaha ayaa si firfircoon u kor u qaadaya cilmi baarista iyo horumarinta ganacsiyada qaboojiyaha heerkulka sare ee gaaska.Intaa waxaa dheer, goobta fal-celinta nukliyeerka nukliyeerka, sida barnaamijka International Thermonuclear Fusion Experimental Reactor (ITER) iyo Japan ee qalabka JT-60 iyo mashaariicda kale ee tijaabinta, garaafyada isostatic ayaa sidoo kale door muhiim ah ka ciyaara.

 

2. Codsiga goobta mashiinka dareeraha korontada

Mashiinka dareeraha korantada waa hab farsamayn sax ah oo aad loo isticmaalo berrinka biraha birta ah iyo mashiinada kale.Habkan, garaafyada iyo naxaasta ayaa caadi ahaan loo isticmaalaa qalabka korantada.Si kastaba ha ahaatee, electrodes graphite ee looga baahan yahay mishiinada dareeraha waxay u baahan yihiin inay buuxiyaan shuruudaha muhiimka ah, oo ay ku jiraan isticmaalka qalabka hooseeya, xawaaraha farsamaynta degdega ah, qallafsanaanta dusha sare, iyo ka fogaanshaha soo-baxa caarada.Marka la barbar dhigo electrodes copper, electrodes graphite waxay leeyihiin faa'iidooyin badan, sida miisaan fudud oo sahlan in la maareeyo, fududahay in la farsameeyo, oo u nugul diiqada iyo kuleylnimada.Dabcan, electrodes graphite sidoo kale waxay la kulmaan caqabado, sida inay u nugul yihiin abuurista boodhka iyo xirashada.Sanadihii la soo dhaafay, electrodes graphite ee mashiinada dareeraha walxaha ultrafine ayaa ka soo baxay suuqa, iyaga oo ujeedadoodu tahay in la yareeyo isticmaalka garaafyada iyo in la yareeyo kala go'a qaybaha garaafka inta lagu jiro mashiinka dareeraha.Suuqgeynta tignoolajiyadani waxay ku xirnaan doontaa heerka tignoolajiyada wax soo saarka ee soo saaraha.

 

3. Bir aan bir ah lahayn oo shubis joogto ah

Biraha aan birta ahayn ee shubista joogtada ah waxay noqotay hab caadi ah oo lagu soo saaro naxaas baaxad weyn, naxaas, naxaas ah, naxaas cad iyo alaabooyin kale.Habkan, tayada crystallizer waxay door muhiim ah ka ciyaartaa heerka u-qalmitaanka badeecada iyo isku-duubnida qaab dhismeedka ururka.Qalabka garaafka riixaya ee isostatic wuxuu noqday doorasho ku habboon samaynta crystallizers sababtoo ah kuleylkeeda kuleylkeeda aadka u fiican, xasilloonida kulaylka, saliidda is-dheellida, qoynta ka hortagga, iyo qallafsanaanta kiimikada.Nooca crystallizer-ka ayaa door muhiim ah ka ciyaara habka shubista joogtada ah ee biraha aan birta ahayn, hagaajinta tayada crystallization ee birta iyo diyaarinta alaabada tuurista tayada sare leh.

 

4. Codsiyada qaybaha kale

Marka lagu daro warshadaha tamarta nukliyeerka, mishiinada dareeraha, iyo birta aan birta ahayn ee shubista joogtada ah, garaafyada istaatigga ah ayaa sidoo kale loo isticmaalaa soo saarista caaryada sintay ee qalabka dheeman iyo alaabo adag, qaybaha goobta kulaylka ee mashiinnada sawir gacmeedka fiber optic (sida. kuleyliyaha, dhululubada dahaarka, iwm), qaybaha goobta kulaylka foornooyinka daaweynta kulaylka faakuumka (sida kuleyliyaha, frames xadhkaha, iwm), iyo sidoo kale saxan graphite kulaylka sarrifka, qaybaha shaabadeynta farsamada, giraangiraha piston, biraha, tuubooyinka gantaalaha, iyo beeraha kale.

 

Marka la soo koobo, garaafka riixitaanka isostatic waa wax badan oo si ballaaran loogu isticmaalo dhinacyo kala duwan sida warshadaha tamarta nukliyeerka, mashiinnada dareeraha, iyo birta aan birta ahayn ee shubka joogtada ah.Waxqabadkeeda aadka u wanaagsan iyo la qabsiga ayaa ka dhigaya mid ka mid ah agabka lagama maarmaanka u ah qaybo badan oo warshado ah.Iyada oo horumarinta joogtada ah ee tignoolajiyada iyo baahida sii kordheysa, rajada codsiga ee garaafka riixitaanka isostatic waxay noqon doontaa mid ballaaran, taasoo keenaysa fursado badan iyo caqabado horumarinta warshadaha kala duwan.
