Ama-slabs e-granite, anobulukhuni bawo obuhle kakhulu, i-coefficient ephansi yokwandisa ukushisa okushisayo, nokuzinza okuphakeme, adlala indima ebalulekile ekulinganisweni okunembayo nokwenza imishini. Ukuqinisekisa ukunemba kwesikhathi eside nokuzinza, ukubunjwa kokwelashwa nokugcinwa okulandelayo kubalulekile. Lesi sihloko sizochaza izimiso nezinqubo zokubunjwa kokwelashwa, kanye namaphuzu abalulekile ekwelapheni nasekugcinweni okulandelayo.
1. Ukwelashwa Kokubumba: Itshe Legumbi Lokunemba Kwesikhathi Eside
Umnyombo wokwelashwa kokubunjwa kwama-granite slabs ukususa izingcindezi zangaphakathi kanye nokuzinzisa i-microstructure, ukubeka isisekelo sokucubungula nokusetshenziswa okulandelayo.
Ukwelapha Ukuguga Kwemvelo
Ama-slabs e-granite atholakala ekwakhiweni kwamadwala angaphansi komhlaba. Ukucindezeleka kwangaphakathi okuyinkimbinkimbi kuye kwanqwabelana ngokuhamba kwesikhathi ngezinqubo ze-geological. Ukuguga okungokwemvelo kuhilela ukuchaya izinto ezimbiwe emvelweni, ukuzifaka ngaphansi komoya, ilanga nemvula iminyaka eminingi. Phakathi nale nqubo, ukushintshashintsha kwezinga lokushisa okujikelezayo, ukuguquguquka komswakama, namandla omoya kancane kancane kukhulula izingcindezi zangaphakathi edwaleni. Isibonelo, idwala liyakhula ngesikhathi samazinga okushisa asehlobo aphezulu kanye nezinkontileka phakathi namazinga okushisa aphansi asebusika. Le deformation ephindaphindiwe kancane kancane ihlakaza futhi ihlakaze izingcindezi. Ngemuva kokuguga kwemvelo, isakhiwo sangaphakathi se-granite siba yinto efanayo, okwenza kube lula ukuguga ngenxa yokukhululwa kwengcindezi ngesikhathi somshini olandelayo, ngaleyo ndlela kuqinisekiswe ukunemba kokuqala kwe-slab.
Ukuguga Okwenziwayo
Kuma-granite slabs adinga ukunemba okuphezulu, ukuguga kwemvelo kukodwa kuvame ukuhluleka ukufeza umphumela oyifunayo. Ngakho-ke ukuguga okwenziwayo kuyadingeka. I-slab ivamise ukubekwa esithandweni esiklanywe ngokukhethekile ukuba sibe nezinga lokushisa elingashintshiyo, sishisiswe kancane sibe yibanga elithile lokushisa, futhi sigcinwe lapho isikhathi eside. Ukushisa okuphezulu kuthuthukisa umsebenzi wezinhlayiya zamaminerali ngaphakathi kwedwala, kuqhubeke nokukhulula ukucindezeleka. Ngokulandelayo, izinga lokushisa liyehliswa kancane kancane, okuvumela isakhiwo sedwala ukuba siqine phakathi nenqubo yokupholisa futhi kuvimbele ukucindezeleka okusha ukuthi kukhiqizwa ukupholisa okusheshayo. Ukuguga okwenziwayo kuvumela ukulawula okunembe kakhudlwana kwezimo zokwelashwa, kufinyeze umjikelezo wokucubungula, futhi kuthuthukise ngokwengeziwe ukuzinza kwe-slab.
I-roughing kanye ne-Semi-finishing
Ngemva kokuguga, i-granite slab iba nama-roughing futhi i-semi-finishing. Phakathi nesigaba esimaholoholo, umshini wokugaya omkhulu noma umshini wokugaya usetshenziswa ukuze kususwe indawo engaphezulu engaphezulu, okuletha i-slab phakathi kobubanzi obucacisiwe bobukhulu. Phakathi nale nqubo, umthamo wokusika kanye nesivinini sokusika kufanele ulawulwe ngokuqinile ukuze ugweme ukusabalalisa kabusha ukucindezeleka ngaphakathi kwe-slab ngenxa yokusika ngokweqile noma amandla okusika angalingani. Ukuqeda kancane, okusekelwe ekuqineni, kuthuthukisa ngokwengeziwe ukucaba kwendawo kanye nokunemba kobukhulu be-slab. Ngokugaya okuphindaphindiwe, ngokucophelela, ubuso be-slab busheleleka kancane kancane, kuyilapho kususwa ngokuqhubekayo ama-micro-stress akhiqizwa ngesikhathi somshini, ukulungiselela ukuqedwa okulandelayo.
II. Ukucubungula Kwangemva Nokunakekela: Ukugcina Ukunemba Okuhle Kakhulu Kwe-Slab
Ama-slabs e-granite angaphansi kwemithelela ehlukahlukene ngesikhathi sokusetshenziswa, okuhlanganisa izici zemvelo nokusetshenziswa, ngakho-ke adinga ukucubungula nokugcinwa okufanele ngemva kokucubungula.
Ukuhlanza Nokugcinwa Kwansuku zonke
Ngesikhathi sokusetshenziswa kwansuku zonke, ama-granite slabs aqoqa kalula ukungcola njengothuli namafutha ezindaweni zawo. Sebenzisa indwangu ehlanzekile, ethambile noma imfucumfucu yezimpaphe ukuze ususe uthuli ngobumnene. Gwema ukusebenzisa izindwangu ezimahhadlahhadla noma amabhulashi anamabristle aqinile, njengoba lokhu kungaklwebha phezulu. Ukuze uthole amabala anenkani njengamafutha, sebenzisa okokuhlanza okungathathi hlangothi. Sula ngobumnene indawo ethintekile ngendwangu ethambile emanziswe ngamanzi ahlanzekile. Hlanza kahle ngamanzi ahlanzekile bese usula ngendwangu eyomile ukuze uvikele umswakama osele kanye namabala amanzi. Ukuhlanza njalo kugcina ukuhlanzeka kwendawo ye-slab futhi kuvimbela ukungcola ukuthi kuphazamise ukunemba kokulinganisa.
Ukulawulwa Kwemvelo
Ama-granite slabs azwela ukushisa okuzungezile kanye nomswakama. Kufanele zigcinwe zisendlini endaweni ezinzile, enomswakama ophakathi, kude nelanga eliqondile kanye namazinga okushisa aphezulu. Ukushintshashintsha kwezinga lokushisa ngokushesha kungabangela i-slab ukuthi inwebeke futhi inciphe, kuthinte ukunemba kwayo kobukhulu. Umswakama owedlulele ungabangela umswakama ukuthi ubambe phezulu, okuholela ekuvuvukeni kwendawo. Futhi, gcina i-slab kude nemithombo yokudlidliza namagesi abolayo, njengoba ukudlidliza kungase kuthinte ukuzinza kwe-slab, kuyilapho amagesi agqwalayo angakwazi ukugqwala indawo engaphezulu futhi afinyeze ukuphila kwayo kwesevisi.
Ukulinganisa Okuvamile Nokulungisa
Ama-slabs e-granite angase alahlekelwe ukunemba kancane kancane ngokuhamba kwesikhathi. Ngakho-ke, ukulinganisa okuvamile kuyadingeka. Sebenzisa amathuluzi okulinganisa anembile ukuze uhlole ukucaba kwe-slab, i-perpendicularity, namanye amapharamitha, futhi wenze ukulungisa okufanele ngokusekelwe emiphumeleni. Ukugqoka okuncane noma ukuklwebheka kungalungiswa ngokugaya ngesandla. Sebenzisa i-abrasive paste ehlanjululwe kahle kanye ne-oilstone, usebenzisa isiqondiso esifanele sokugaya kanye nokucindezela ukuze ubuyisele kancane kancane ukunemba kwendawo ye-slab. Ukugqokwa okunamandla kudinga ukucutshungulwa kabusha ngumqambi onekhono.
