Emkhakheni wemishini yokumboza ukubonisa, isisekelo se-granite, njengengxenye eyisisekelo eyinhloko, sidlala indima ebalulekile ekuzinzeni, ekunembeni nasekuphileni kwenkonzo yemishini. I-China ne-Europe ne-America ngayinye inezimpawu zayo ekusetshenzisweni nasekuthuthukisweni kobuchwepheshe kwezisekelo ze-granite. Lesi sihloko sizokwenza ukuhlaziywa okuqhathanisayo kusuka ezicini eziningi ukuze kunikezwe ireferensi ephelele yabasebenzi bemboni nabalandeli.
I. Ukuqhathaniswa Kwezinqubo Zobuchwepheshe: Ngayinye inezinzuzo zayo
IYurophu neMelika baqale ngaphambilini emkhakheni wokucubungula isisekelo se-granite. Ukuqongelela isikhathi eside kubanikeze ithuba lokusebenzisa amasu okucubungula ngokunemba okuphezulu. Isibonelo, amabhizinisi aseJalimane asebenzise ubuchwepheshe bokugaya obuncane, obungalawula ukujiya kobuso be-granite ngaphakathi kwe-Ra≤0.1μm futhi bufinyelele ukuqina okungu-±0.5μm/m, okwenza kufaneleke imishini yokumboza ebonakalayo enezidingo zokunemba okuphezulu kakhulu. Abanye abakhiqizi e-United States banekhono lobuchwepheshe bokucubungula obuhlanganisiwe, behlanganisa i-granite nezinto zensimbi ezikhethekile ukuze bathuthukise izakhiwo zemishini zesisekelo.
Eminyakeni yamuva nje, iShayina ibilokhu ifinyelela ngokushesha kwezobuchwepheshe, ikakhulukazi ezinqubweni zokukhiqiza ezinkulu kanye nokucubungula okwenziwe ngokwezifiso. Amabhizinisi asekhaya angaqeda ngempumelelo ukucutshungulwa kwezisekelo ze-granite eziyinkimbinkimbi ngokusebenzisa izikhungo zawo zomshini wokuxhumanisa ezihlanganisiwe ezizimele ezithuthukiswe ngokuzimela. Ngaphezu kwalokho, ngohlelo lokuqapha ikhwalithi yedatha enkulu, izinga lokufaneleka komkhiqizo lingakhushulwa libe ngaphezu kuka-98%. Ngokuhlanganisa ukwethulwa kwemishini ethuthukisiwe yamazwe ngamazwe kanye nokusungula izinto ezintsha okuzimele, i-ZHHIMG® ifinyelele umthamo wokukhiqiza waminyaka yonke wezisekelo ze-granite ezingaphezu kuka-10,000 ngenkathi iqinisekisa ukunemba okuphezulu, ihlangabezana nezidingo ezinkulu zezimakethe zasekhaya nezamazwe ngamazwe.
Okwesibili, ukusebenza kwezindleko kanye nezindleko: Imikhiqizo yasekhaya inezinzuzo ezibalulekile
Ngenxa yokutshalwa kwezimali okukhulu ocwaningweni lwezobuchwepheshe kanye nentuthuko kanye nezindleko eziphezulu zabasebenzi, amanani ezisekelo ze-granite eYurophu naseMelika ngokuvamile aphezulu. Thatha isisekelo se-granite esinembile kakhulu sencazelo efanayo (1500mm × 1000mm × 200mm) njengesibonelo. Intengo yemikhiqizo evela eYurophu naseMelika ivame ukuba phakathi kwamadola aseMelika angu-30,000 no-50,000, kanti intengo yemikhiqizo efanayo eShayina ingu-20,000 kuya ku-40,000 RMB kuphela, okunenzuzo enkulu yezindleko.
Ngokuphathelene nokusebenza kahle kwezindleko, imikhiqizo evela ezweni lethu isebenze kahle kakhulu. Amabhizinisi asekhaya anciphise kakhulu izindleko ngokwenza ngcono ukuphathwa kochungechunge lokuhlinzekwa, afinyelele ekukhiqizweni okuhlanganisiwe kusukela ekumbiweni kwezinto zokusetshenziswa ze-granite kuya ekucutshungulweni kwemikhiqizo eqediwe. Ngesikhathi esifanayo, ngaphansi kwesisekelo sokuqinisekisa ukusebenza okuyisisekelo (njengobuningi obungu-3100kg/m³ kanye namandla okucindezela angu-≥200MPa), ukuncintisana komkhiqizo kuthuthukiswa ngokusungula izinto ezintsha kwezobuchwepheshe, okwenza ufaneleke kakhulu kumabhizinisi amancane naphakathi nendawo azwela izindleko kanye nezimo zokuthengwa okukhulu.
Iii. Umehluko Wokusetshenziswa Kwemakethe: Ukuthambekela kwesidingo kunquma izici
Izisekelo ze-granite zaseYurophu naseMelika zisetshenziswa kakhulu emishinini eyenziwe ngokwezifiso ephezulu, njengemishini yokumboza ikhabethe yokubonisa yokunethezeka kanye nemigqa yokumboza izingxenye zokunemba kwendiza, njll. Lezi zinsimu zinezidingo eziphakeme kakhulu zokuzivumelanisa nezimo zemvelo kanye nokuqina okunembile kakhulu kwezisekelo. Isibonelo, emishinini ethile yokumboza iwashi ephezulu eSwitzerland, isisekelo se-granite saseYurophu naseMelika esisetshenziswayo sidinga ukudlula ukuhlolwa okuqinile kokuphazamiseka kwe-electromagnetic kanye nokuhlolwa kokujikeleza kokushisa okuphezulu nokuphansi.
Izisekelo ze-granite ezweni lethu zisetshenziswa kabanzi emishinini yokumboza eboniswa ngabathengi abaningi ngenxa yokusebenza kwazo okubiza kakhulu, njengemigqa yokumboza ye-casing yocingo kanye nemishini yokumboza ifenisha ebusweni. Okwamanje, emikhakheni emisha efana nemakethe yemishini yokumboza ye-casing entsha yebhethri yezimoto zamandla, imikhiqizo yasekhaya nayo ifinyelele ngokushesha. Ngokuphendula okusheshayo kanye nezinsizakalo ezenziwe ngokwezifiso, zihlangabezana nezidingo ezahlukahlukene zamakhasimende.
Iv. Izitayela Zentuthuko Yesikhathi Esizayo
IYurophu ne-United States zizoqhubeka nokugxila ocwaningweni nasekuthuthukisweni kobuchwepheshe obusezingeni eliphezulu, zihlole ukusetshenziswa okuhlanganisiwe kwe-granite nezinto ezintsha, futhi zithuthukise ukusebenza kwesisekelo. Ngokusekelwe ekuhlanganiseni izinzuzo zayo ezikhona, iChina ikhulise ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni, yakhuthaza ukuthuthuka kwezimboni ziye ezingeni eliphezulu, yaqinisa ukuvumelana nezindinganiso zomhlaba wonke, futhi yathuthukisa ukuncintisana kwayo emakethe yomhlaba wonke enezinga eliphezulu. Enkambisweni yokushintshana kobuchwepheshe kanye nokuncintisana kwemakethe, izinhlangothi zombili kulindeleke ukuthi zikhuthaze ngokubambisana intuthuko entsha yezisekelo ze-granite emkhakheni wemishini yokuhlobisa yokubonisa.
Kungakhathaliseki ukuthi ukhetha imikhiqizo yesisekelo se-granite evela eShayina noma eYurophu naseMelika, amabhizinisi kufanele acabangele kabanzi ngokusekelwe ezidingweni zawo zemishini, isabelomali kanye nezimo zokusetshenziswa. Ukuze uthole ulwazi olwengeziwe ngemikhiqizo yesisekelo se-granite kanye nezixazululo zobuchwepheshe, sicela uqaphele izitayela zemboni noma uxhumane nabaphakeli abangochwepheshe ngezinsizakalo ezenziwe ngokwezifiso.
