Emhlabeni we-Metal Face, ukwelashwa kwensimbi engaphezulu kuyinqubo ebucayi ethuthukisa ukuqina kokusebenza, ukukhalaza ngobuhle, kanye nokumelana nokugqwala. E-Jindalai Steel Company, sisebenza ngokukhethekile ekuhlinzekeni imikhiqizo yensimbi esezingeni eliphakeme, futhi siyakuqonda ukubaluleka kwezindlela zokwelashwa ezisebenzayo. Le bhulogi izokwengeza ebuchwepheshe obuhlukahlukene bokuphathwa kwensimbi engaphezulu komhlaba, bagxile ezinqubweni ezivame kakhulu: ukugaywa kanye nokuhamba.
Iziphi izindlela zokwelashwa komhlaba zensimbi engenasici?
Izindlela zokwelashwa ezingaphezulu zensimbi engenasici zingahlukaniswa kabanzi ezinqubweni zemishini kanye namakhemikhali. Izindlela ezenziwa ngomshini zifaka ukucwaswa, ukugaya, nokuqhuma, okuguqula indawo emzimbeni ukuze kuthuthukise ukuqeda kwayo nokususa ukungapheleli kwayo. Izindlela zamakhemikhali, ngakolunye uhlangothi, zifaka ukusetshenziswa kwezixazululo ezithile zokuthola izakhiwo ezifiselekayo, njengokumelana nokukhulisa okuthuthukile.
I-Pickling and Privivation: Izinqubo ezibalulekile
Izinqubo ezimbili zokwelashwa kwamakhemikhali ezisetshenziswa kakhulu zensimbi engagqwali yensimbi engagqwali ziyakha futhi ziwukuphambuka.
I-Pickling iyinqubo esusa oxides, isikali, kanye nokunye ukungcola kusuka ebusweni bensimbi engenasici. Lokhu ngokujwayelekile kutholakala kusetshenziswa ingxube yama-acid, njenge-hydrochloric noma i-sulfuric acid. Inqubo yokukhukhulisa ayihlambi nje kuphela kodwa futhi ikulungiselele ukuthola ezinye izindlela zokwelapha, iqinisekisa ukunamathela okuphelele kwezingubo noma ukuqeda.
Ukuqhamuka, ngakolunye uhlangothi, kuyinqubo ethuthukisa ungqimba we-oxide wemvelo ngensimbi engenasici, ukuhlinzeka ngesithiyo esingeziwe sokugqwala. Lokhu kuvame ukufezekiswa ukwelapha insimbi ngesisombululo esiqukethe i-citric noma i-nitric acid. Ukuphumelela kubalulekile ukuze kugcinwe ubuqotho bensimbi engenasici ezindaweni ezinokhahlo, okwenza kube yisinyathelo esibalulekile kwinqubo yokwelashwa engaphezulu.
Imiyalo ethile yokuthathwa kanye nokuhamba
Uma kukhulunywa ngokuthathwa nokuphambukisa, kulandela imiyalo ethile kubalulekile ukuze kufezekise imiphumela emihle kakhulu.
1. Ukukha imiyalo yokwelashwa:
- Qinisekisa ukuthi ingaphezulu insimbi engenasici ihlanzekile futhi ikhululekile kumafutha noma ukungcola.
- Lungiselela isisombululo sokukhahlela ngokuya ngemihlahlandlela yomenzi, uqinisekise ukugcwala okulungile kwama-acid.
- Gxila izingxenye zensimbi ezingagqwali kwikhambi lesikhathi esinconyiwe, ngokuvamile kusuka emizuzwini embalwa kuya emahoreni ambalwa, kuya ngobukhulu besendlalelo se-oxide.
- Hlambulula kahle ngamanzi ukuze ungathathi hlangothi i-acid bese ususa noma yiziphi izinsalela.
2. Ukuhanjiswa kwemiyalo yokwelashwa:
- Ngemuva kokukhanyisa, hlambulula izingxenye zensimbi ezingagqwali ukuze ususe noma iyiphi i-acid esele.
- Lungiselela ikhambi lokuphambuka, Ukuqinisekisa ukuthi lihlangabezana nemininingwane edingekayo.
- Faka insimbi engenacala kwikhambi lokuhamba kwesikhathi sesikhathi esinconyiwe, imvamisa phakathi kwemizuzu engama-20 kuye kwangama-30.
- Hlambulula ngamanzi e-deionized ukususa noma yisiphi isisombululo sokuphumula esisele bese umisa izingxenye ngokuphelele.
Umehluko phakathi kokukhanyisa nokuhamba
Ngenkathi bobabili ukukha khona nokufudumeza kubalulekile ekwelashweni okungagqwali kwensimbi, kusebenza ngezinhloso ezihlukile. I-Pickling igxile ngokuyinhloko ekuhlanzeni ingaphezulu futhi isusa ama-contaminants, ngenkathi ukudlula kuhlose ukuthuthukisa ungqimba oluvikelayo ongi, ngcono ukumelana nokugqwala. Ukuqonda lokhu kwehluka kubalulekile ekukhetheni indlela efanele yokwelashwa ngokususelwa kwisicelo esithile kanye nezimo zemvelo.
Ukugcina
E-Jindalai Stone Company, siyabona ukuthi ukwelashwa kwensimbi engenasici akusona nje isinyathelo enqubweni yokukhiqiza; Kuyingxenye ebalulekile enquma ubude obude nokusebenza komkhiqizo wokugcina. Ngokusebenzisa ubuchwepheshe bokwelashwa bensimbi obusezingeni eliphezulu obungelutho, kufaka phakathi ukugaya nokufakelwa, siqinisekisa ukuthi imikhiqizo yethu ihlangabezana namazinga aphezulu kakhulu wekhwalithi nokuqina. Noma ngabe uswele ngensimbi engenasici ekwakheni, izimoto, noma yimuphi omunye imboni, ubuchwepheshe bethu ezinqubweni zokwelashwa kwensimbi ziqinisekisa ukuthi uthole izixazululo ezinhle kakhulu zezidingo zakho.
