Emkhakheni wokuhlolwa komshini okunembile, ukunemba nokuthembeka kwezinsimbi zokuhlola izikulufo ze-lead kuthinta ngqo ukulawulwa kwekhwalithi yezingxenye zokudlulisa zomshini. Ukukhethwa kwezinto zezingxenye eziyinhloko ze-lead screw detector kuyisihluthulelo sokunquma impilo yesevisi kanye nokusebenza kwemishini. Ingxenye ekhethekile ye-granite yezinsimbi zokuhlola izikulufo ze-lead, enezinzuzo zayo ezivelele zesayensi yezinto ezibonakalayo, ifinyelele impumelelo yokwandisa impilo yesevisi ngeminyaka eyi-12 uma kuqhathaniswa nezinto zensimbi eziphonswe, okuletha ushintsho olukhulu embonini yokuhlola okunembile.
Imikhawulo yezingxenye zensimbi ephonswe
Insimbi ephothiwe ibilokhu iyinto esetshenziswa kakhulu ekukhiqizeni izingxenye zezinsimbi zokuhlola izikulufo ze-lead ngenxa yezindleko zayo eziphansi kanye nokuqina okuthile. Kodwa-ke, insimbi ephothiwe inezinkinga eziningi ekusetshenzisweni okusebenzayo. Okokuqala, insimbi ephothiwe ayinakho ukuzinza kokushisa okuhle. Ngesikhathi sokusebenza kwe-lead screw detector, ukushisa okukhiqizwa yimishini ngokwayo kanye nezinguquko ekushiseni kwemvelo kungabangela ukuguqulwa kokushisa kwezingxenye zensimbi ephothiwe, okuthinta ukunemba kokutholwa kwesikulufo se-lead. Njengoba isikhathi sokusetshenziswa sanda, umphumela oqongelelekayo wokuguqulwa kokushisa uzobangela ukuthi iphutha lokulinganisa likhule njalo. Okwesibili, ukumelana nokuguguleka kwensimbi ephothiwe kunqunyelwe. Ngesikhathi sokunyakaza okuphindaphindiwe kwesikulufo se-lead kanye nokusebenza kokuhlola, ubuso bengxenye yensimbi ephothiwe buvame ukuguguleka ngenxa yokungqubuzana, okuholela ekwandeni kokuvuleka kokulingana futhi ngaleyo ndlela kuncishiswe ukunemba nokuthembeka kwemishini yokuhlola. Ngaphezu kwalokho, insimbi ephothiwe inokumelana nokugqwala okubuthakathaka. Ezindaweni ezimanzi noma eziqukethe igesi ebolile, izingxenye zensimbi ephothiwe zivame ukugqwala nokugqwala, okunciphisa kakhulu impilo yenkonzo yemishini.
Izinzuzo zesayensi yezinto ezibonakalayo zezingxenye ze-granite
I-Granite, njengezinto ezifanele izingxenye ezizinikele zezinsimbi zokuhlola izikulufo ze-lead, inezinzuzo zemvelo zomzimba. Isakhiwo sayo sangaphakathi siminyene futhi sifana, sine-coefficient ephansi kakhulu yokwanda kokushisa, ngokuvamile kusukela ku-5 kuya ku-7×10⁻⁶/℃, futhi cishe ayithinteki yizinguquko zokushisa. Lokhu kwenza i-lead screw detector ikwazi ukugcina ubukhulu obuzinzile kanye nokwakheka kwezingxenye ze-granite ngisho nangaphansi kokusebenza kwesikhathi eside noma ukushintshashintsha okukhulu kokushisa kwemvelo, okuhlinzeka ngereferensi ethembekile yokuthola izikulufo ze-lead kanye nokuqinisekisa ukunemba kwedatha yokulinganisa.
Ngokuphathelene nokumelana nokuguguleka, ubulukhuni be-Mohs be-granite bungafinyelela ku-6-7, okuphakeme kunokwensimbi ephonswe. Ngesikhathi sokunyakaza okuvamile kwesikulufu se-lead, ubuso bengxenye ye-granite abugugi kalula futhi buhlala bugcina indawo efanelekile, okuqinisekisa ukuzinza kwesikhathi eside kokutholwa kwesikulufu se-lead. Ngokwezibalo zedatha yokusetshenziswa okusebenzayo, izinga lokwehla kokunemba kwesitholi sesikulufu se-lead sisebenzisa izingxenye ze-granite lihamba kancane ngaphezu kuka-80% kunezingxenye zensimbi ephonswe ngaphansi kwezimo ezifanayo zokusebenza.
Ngokuphathelene nokumelana nokugqwala, i-granite iyitshe lemvelo elinezakhiwo zamakhemikhali ezizinzile futhi alisabelani nezinto ezivamile ze-acidic noma ze-alkaline. Ngisho nasezindaweni eziyinkimbinkimbi zezimboni, izingxenye ze-granite ngeke zonakaliswe ukugqwala, okwandisa isikhathi senkonzo yesitholi sesikulufu se-lead.
Imiphumela emihle kakhulu yokusetshenziswa kanye nenani lemboni
Umphumela wokusetshenziswa okusebenzayo kwezingxenye ezikhethekile ze-granite zezihlungi zezikulufo ze-lead uyamangalisa kakhulu. Ngokulandela uphenyo lwamabhizinisi amaningi okukhiqiza imishini, kutholakale ukuthi impilo yesevisi ephakathi nendawo yezihlungi zezikulufo ze-lead ezisebenzisa izingxenye zensimbi ephonswe cishe iminyaka eyi-8, kanti ngemva kokusebenzisa izingxenye ze-granite, impilo yesevisi yezihlungi zezikulufo ze-lead ingandiswa ibe yiminyaka engama-20, ukwanda kweminyaka eyi-12 egcwele. Lokhu akugcini nje ngokunciphisa kakhulu izindleko zamabhizinisi zokushintsha imishini yokuhlola, kodwa futhi kunciphisa isikhathi sokungasebenzi esibangelwa ukungasebenzi kahle kwemishini futhi kuthuthukisa ukusebenza kahle kokukhiqiza.
Ngokombono wokuthuthukiswa kwemboni, ukusetshenziswa kwezingxenye ze-granite kukhuthaze ukuthuthuka kobuchwepheshe bokuthola ukunemba. Ukuphila kwayo isikhathi eside kakhulu kwenkonzo kanye nokusebenza kwayo okuzinzile kunikeza isiqinisekiso esithembekile sokuhlolwa kwezikulufo ze-lead ezinembile kakhulu, kusiza imboni yokukhiqiza yemishini ukukhiqiza imikhiqizo esezingeni eliphezulu kanye nokuthuthukisa ukuncintisana kwayo yonke imboni.
Izingxenye ezikhethekile zegranite zezinsimbi zokuhlola izikulufo ze-lead zinqobe ngempumelelo amaphutha ezingxenye zensimbi ephonswe ngenxa yezinzuzo zesayensi yezinto ezibonakalayo, zafinyelela ukwanda okukhulu empilweni yesevisi. Esikhathini esizayo, ngokwanda okuqhubekayo kwesidingo sokuhlolwa kokunemba, izingxenye zegranite nakanjani zizodlala indima ebalulekile emikhakheni eminingi futhi zinikeze ukwesekwa okuqinile ekuthuthukisweni kwemboni yokukhiqiza ngokunemba.
