Amandla oxhumano lwentambo eqondile njengokuhlangana okuqiniswe ngokuhlanganyela ngeminyaka yama-90s wekhulu lama-20 yinkambo yakamuva yomhlaba, ikhwalithi ehlanganyelwe eqinile enokwethenjelwa, amandla ahlangene aphezulu, alingana nalawo okuhlanganisa imikhono okuxova amabhuloho, futhi inomsebenzi wokwakha ngokuhlanganyela we-taper. , izici zejubane, ngaleyo ndlela zethulwe ensimbi eqondile yokuxhuma amakhono amakhono okuhlanganisa alethe i-prance yekhwalithi.Njengamanje, kunezinhlobo eziningi zezindlela zokuxhuma intambo eqondile ezweni lethu.
Isixhumi sentambo eqondile ikakhulukazi sihlanganisa isixhumi somucu oqondile ophazamisayo kanye nesixhumi somucu oqondile ogoqayo.Lezi zinqubo ezimbili zikhetha izindlela ezihlukene zokucubungula, zithuthukise umthamo wokuthwala wentambo yokugcina yensimbi, ukuze kufinyelelwe into eyisisekelo ehlangene neyokuqinisa kanye nenye inhloso eqinile.
Ukuhlanganiswa kwentambo eqondile ecasulayo: inhlanganisela eyakhiwe ngokuvaleka kwentambo eqondile kanye nezintambo zokuxhuma ezenziwe ngokuphazamisa ukuphela kwensimbi.Inqubo ithi:
Okokuqala, ukuphela kwebha yensimbi kucasulwa yimishini ephazamisayo, bese intambo icutshungulwa.Ububanzi bentambo abukho ngaphansi kobubanzi besisekelo sensimbi yensimbi, ukuze izinto ezihlangene nesisekelo zifinyelele amandla alinganayo.Ilunga lentambo eliqondile lakwamanye amazwe, isiphetho salo sensimbi sinokuphazamisa okushisayo kanye nokuphazamiseka okubandayo.Inhloso eyinhloko yokushisa okushisayo ukuqeda ukucindezeleka kwangaphakathi ngesikhathi sokuphazamiseka, kodwa izindleko zemishini yokushisa ziphezulu.Ezweni lakithi, isiphetho sebha yensimbi yokuhlanganisa intambo eqondile ikakhulukazi iphazamisa amakhaza, enesidingo esikhulu se-ductility yensimbi yensimbi.Kubha yensimbi ene-ductility ephansi, ikhwalithi ephazamisayo kunzima ukuyilawula, futhi kulula ukuvela njengokubukeka kwe-brittle fracture.
Izinzuzo zokucasula intambo ehlangene inamandla amakhulu, isivinini sokwakhiwa kwesayithi esisheshayo, umfutho ophansi wabasebenzi, ikhanda lentambo yensimbi eqondile konke okwenziwe kusengaphambili, ukuxhunywa kwendawo ukuze kufakwe.Ukuntuleka ilele inqubo ecasulayo kulula ukuvela ukubukeka okucasulayo, once ukucasula kuyadingeka ukunqamula ukucasula kabusha;Phakathi nenqubo ecasulayo, ingcindezi yangaphakathi iyenzeka, i-ductility ethile yensimbi iyancipha, futhi kulula ukwenza ukubukeka okuphukile okuphukile.Ukucutshungulwa kwentambo yesikulufu kudinga izinqubo ezimbili namasethi amabili wezinto zokusebenza ukuze kuqedelwe.
Isixhumi sentambo egoqayo eqondile: ilunga elakhiwe ngokulunywa kwentambo eqondile nemicu yesixhumi eyenziwe ngokugingqa ngokuqondile noma ukukhama (ukugoqa) ubambo ekugcineni kwensimbi noma ngemva kokuhlubula ubambo.
Okwesithathu, ijoyinti lokuxova imikhono: ngemva kokuxova amandla okwenza ukuwohloka kwepulasitiki okuhlangene komkhono wensimbi kanye nensimbi enezimbambo evalwe ngokuqinile ngokuhlanganyela.Kunezindlela ezimbili, ukuxhumana kwe-radial kneading kanye nokuxhumeka kwe-axial kneading.Ngenxa yokuthi ukwakhiwa kwesizinda esihlangene se-axial akulula futhi ikhwalithi ehlangene ayizinzile, ayizange isetshenziswe;Amakhono okuxova ama-radial namajoyinti asetshenziswe kabanzi.Manje amajoyinti okuxova imikhono asetshenziswa kule phrojekthi asengamajoyinti okuxova ama-radial.Ngenxa yekhwalithi yayo enhle kakhulu, izixhumi zokuxova imikhono bezisetshenziswa kakhulu kwezobunjiniyela bokwakha eChina kusukela ekuqaleni kwawo-1990 kuze kube manje.
