Indima yesikhunta se-graphite ekuqiniseni

Isikhunta se-graphite sidlala indima ebalulekile ekubhuleni, ikakhulukazi okuhlanganisa izici ezilandelayo:

• I-Fixed futhi ibekwe ukuze kuqinisekiswe ukuthi i-weldment igcina isikhundla esizinzile ngesikhathi senqubo yokubhoboza, ivimbele ukuthi inganyakazi noma iphazamiseke, ngaleyo ndlela iqinisekise ukunemba kanye nekhwalithi ye-welding.
  Ukudlulisa ukushisa nokulawula izinga lokushisa Ngenxa yokuthi i-graphite ine-conductivity enhle yokushisa, ingakwazi ukudlulisa ukushisa ngokushesha nangokulinganayo, okusiza ukulawula ukusatshalaliswa kwezinga lokushisa ngesikhathi senqubo yokubhoboza, ukuze izinto zokubhoboza zincibilike ngokugcwele futhi zigcwalise i-weld ukuze kuzuzwe ukuxhumana okuhle.
  Ukwakha umumo othile kanye nesakhiwo Kungaklanywa kube yisimo esithile kanye nesakhiwo njengoba kudingeka ukuze kusize ukwakha ijoyinti lokushisela kanye nokuma kwe-weldment ehlangabezana nezidingo.
  Umthelela ovikelayo Inikeza ukuvikeleka okuthile kokushisela futhi inciphisa ukuphazamiseka kanye nomthelela wemvelo yangaphandle enqubweni yokubhula, njengokuvimbela i-oxidation.

Ukubunjwa kwe-graphite kunezinzuzo eziningi ezibalulekile zokubhula:

• Ukusebenza kahle kakhulu kwe-thermal Ingakwazi ukudlulisa ukushisa ngokushesha, yenze i-brazing incibilike ngokulinganayo, ithuthukise ukusebenza kahle kanye nekhwalithi yokuxhumana Ukumelana kahle nezinga lokushisa eliphezulu Ingahlala izinzile endaweni yokushisa ephezulu, akulula ukuyilimaza noma ukulimaza.
  Ukuzinza kwamakhemikhali aphezulu Akulula ukusabela ngamakhemikhali nge-brazing material kanye ne-weldment, ukuqinisekisa ukuhlanzeka nokuzinza kwenqubo ye-welding.
  Izindleko eziphansi uma kuqhathaniswa nezinye izinto ezimelana nokushisa okuphezulu, izindleko zokubumba amatshe ziyonga kakhulu, okusiza ekunciphiseni izindleko zokukhiqiza.

Ukubunjwa kwe-graphite kunethonya elibalulekile kwikhwalithi yokubhula:

• Okuthinta umphumela wokugcwalisa we-weld
  Isikhunta esifanelekile se-graphite singaqinisekisa ukuthi i-brazing material igcwalisa ngokugcwele i-weld, yakha i-uniform kanye ne-dense welded joint, futhi ithuthukise amandla nokuvalwa kwesihlanganisi.
  Nquma i-microstructure yelunga
  Ukusebenza kokudlulisa ukushisa kanye nokuma kwesikhunta kuzothinta ukusatshalaliswa kwezinga lokushisa nezinga lokupholisa phakathi nenqubo yokubhula, ngaleyo ndlela kuthinte i-microstructure nokusebenza kwelunga.
  Ithinta ukunemba kwe-dimensional kwe-weldment
  Ukunemba kwesikhunta kuhlobene ngokuqondile nokunemba kwe-dimensional ye-weldment. Uma ukunemba kwesikhunta kungephezulu, kungabangela ukuchezuka kwe-dimensional ye-weldment futhi kuthinte ukusebenza kwayo.
