Nguwuphi umahluko phakathi kwezitena zodongwe kunye nenqanaba eliphezulu lezitena zealumnium?

Umahluko ophambili phakathi kwezitena zodongwe kunye nezitena eziphakamileyo zealumumina ngumxholo wealuminium kunye noxinano olukhulu.

Izitena ezinomxholo wealuminium ezingama-40-48 zizitena zodongwe. Izitena zodongwe zinezikhombisi ezahlukeneyo ze-N-1, N-2, N-3, kunye ne-N-4 kumgangatho kazwelonke. Kwimveliso kunye nokusetyenziswa, izitena zodongwe i-N-2, N- 3 zisetyenziswa kakhulu, kwaye zikwayimveliso eqhelekileyo eveliswa ngabavelisi abaninzi. Ukuxinana kwevolumu kuphakathi kwe-2.1-2.15. Kwimeko yezitena zodongwe ze-N-1, ezinye izalathi zingaphezulu kunebakala lesithathu lezitena zealumnium.

Izitena ezinomxholo we-aluminium engama-55% zikumgangatho wesithathu wezitena ze-alumina ezinobuninzi bobuninzi phakathi kwe-2.15-2.25. Okwangoku, ngenxa yendawo yemveliso kunye nezinto ezingavunyelwanga, umxholo wealuminium kwizitena zodongwe zimalunga nama-56%. Umxholo wealuminium kwizitena zodongwe eXinmi, eHenan imalunga nama-56%, kwaye uxinano lomzimba lungaphezulu kwe-2.15, esisiseko sezitena ezikumgangatho wesithathu. Ngapha koko, iqondo lokudubula liphezulu, kwaye isalathiso semichiza asikho ngaphantsi kwebakala lesithathu lezitena zealumnium, kodwa yahlukile kubushushu bokuthambisa umthwalo.

Umxholo we-aluminium kwizitena eziphakamileyo ezintathu zealumni eziveliswe ngoku zimalunga nama-63%, kwaye ezinye zinama-65%. Ubuninzi bomzimba bungaphezulu kwe-2.25, kwaye umthwalo othomalalisa ubushushu uphantsi kancinci. Ngokumalunga nezalathi zeekhemikhali, yahlukile kuphela kwibakala lesibini izitena zealumum ephezulu kubunzima beyunithi kunye nomthwalo wobushushu obuthomalisayo.

Umbala wokubonakala kwezitena zodongwe kunye nezitena eziphakamileyo ze-alumina ezikumgangatho wesithathu zahlukile. Izitena zodongwe zibomvu-tyheli, kunye nezitena ezikumgangatho wesithathu ezine-alumina ezimhlophe zimthubi.

Kukho umahluko kubunzima phakathi kwezitena zodongwe kunye nebakala lesithathu ngezitena eziphezulu zealumni. Izitena ezifanayo zodongwe zilula kunebanga lesithathu lezitena eziphezulu zealumni. Iqondo lokudubula nalo lisezantsi nge-20-30 ° C.

Izitena zodongwe kunye nebakala lesithathu izitena eziphezulu zealumina zinomahluko kumandla oxineneyo kunye nomthwalo wokunciphisa ubushushu. Amandla okucinezelwa kwezitena zodongwe yi-40Mpa, ngelixa amandla oxineneyo ebakala lesithathu kwizitena eziphezulu zealumni yi-50Mpa. Umthwalo othambileyo wezitena zodongwe ukwangaphezulu kunowebanga lesithathu. Ukuphinda kubambe isitena sealuminium ngama-30 ukuya kuma-40 ℃, kwaye ukuphindaphinda kwaso kumalunga nama-30 ℃ asezantsi.
