Kwihlabathi lokwenziwa kwesinyithi, unyango lomphezulu wentsimbi engagqwali yinkqubo ebalulekileyo ephucula ukuqina kwento, ukuthandeka kobuhle, kunye nokumelana nokugqwala. KwiJindalai Steel Company, sigxile ekuboneleleni ngeemveliso zentsimbi engagqwali ezikumgangatho ophezulu, kwaye siyaqonda ukubaluleka kweendlela ezisebenzayo zokunyanga umphezulu. Le bhlog iza kujonga kwiindlela ezahlukeneyo zokunyanga umphezulu wentsimbi engagqwali, igxile kwiinkqubo eziqhelekileyo: ukukhaba kunye nokudlulisa inkunkuma.
Ziziphi iindlela zokuNyangwa koMphezulu weNtsimbi engagqwaliyo?
Iindlela zokunyanga umphezulu wentsimbi engagqwaliyo zingahlulwahlulwa ngokubanzi ngokweenkqubo zoomatshini nezeekhemikhali. Iindlela zoomatshini ziquka ukupolisha, ukugaya, kunye nokuqhumisa, okutshintsha ngokwasemzimbeni umphezulu ukuze kuphuculwe ukugqitywa kwawo kwaye kususwe iziphene. Iindlela zekhemikhali, kwelinye icala, ziquka ukusetyenziswa kwezisombululo ezithile ukuze kufezekiswe iipropati ezifunekayo, ezinje ngokumelana nokugqwala okuphuculweyo.
Ukukha kunye nokuPasa: Iinkqubo eziphambili
Iindlela ezimbini zekhemikhali ezisetyenziswa kakhulu ekunyangweni komphezulu wentsimbi engagqwaliyo kukucoca nokukhupha isinyithi.
Ukugalela yinkqubo esusa ii-oxides, isikali, kunye nezinye izinto ezingcolisayo kumphezulu wentsimbi engagqwaliyo. Oku kwenzeka kusetyenziswa umxube wee-asidi, ezifana ne-hydrochloric okanye i-sulfuric acid. Inkqubo yokugalela ayicoci nje kuphela umphezulu kodwa ikwawulungiselela unyango olongezelelweyo, iqinisekisa ukunamathela ngokugqibeleleyo kweengubo okanye ukugqitywa.
Kwelinye icala, i-passivation yinkqubo ephucula umaleko we-oxide yendalo kwintsimbi engatyiwayo, nto leyo enika umqobo owongezelelweyo wokulwa nokugqwala. Oku kudla ngokufezwa ngokunyanga isinyithi ngesisombululo esine-citric okanye i-nitric acid. I-passivation ibalulekile ekugcineni ukuthembeka kwentsimbi engatyiwayo kwiindawo ezinzima, nto leyo eyenza kube linyathelo elibalulekileyo kwinkqubo yonyango lomphezulu.
Imiyalelo Ethile Yokukha Nokuthambisa
Xa kufikwa ekutyibilikeni nasekuthambiseni ukutya, ukulandela imiyalelo ethile kubalulekile ukuze kufunyanwe iziphumo ezilungileyo.
1. Imiyalelo yoNyango lokuCoca:
– Qinisekisa ukuba umphezulu wentsimbi engagqwaliyo ucocekile kwaye awunamafutha okanye ukungcola.
– Lungisa isisombululo sokucola ngokwezikhokelo zomenzi, uqinisekise ukuba kukho uxinano oluchanekileyo lwee-asidi.
– Nciphisa iindawo zentsimbi engagqwaliyo kwisisombululo kangangexesha elicetyiswayo, ngokwesiqhelo ukusuka kwimizuzu embalwa ukuya kwiiyure ezininzi, kuxhomekeke kubukhulu bomaleko we-oxide.
– Hlamba kakuhle ngamanzi ukuze unciphise i-asidi kwaye ususe nayiphi na intsalela.
2. Imiyalelo yoNyango lokuPhumla:
– Emva kokukha, hlambulula iindawo zentsimbi engagqwaliyo ukuze ususe nayiphi na i-asidi eseleyo.
– Lungisa isisombululo sokungasebenzisi sixhobo, uqinisekise ukuba siyahlangabezana neemfuno ezifunekayo.
– Nciphisa intsimbi engagqwaliyo kwisisombululo sokudlulisa amanzi kangangexesha elicetyiswayo, ngesiqhelo phakathi kwemizuzu engama-20 ukuya kwengama-30.
– Hlamba ngamanzi acocekileyo ukuze ususe nasiphi na isisombululo sokungashukumi esisele kwaye womise iindawo ngokupheleleyo.
Umahluko Phakathi koKukha kunye nokuPhumla
Nangona zombini ukucola kunye nokuphazamisa kubalulekile ekunyangweni komphezulu wentsimbi engagqwaliyo, zisebenza ngeenjongo ezahlukeneyo. Ukucola kugxile kakhulu ekucoceni umphezulu kunye nokususa izinto ezingcolisayo, ngelixa ukuphazamisa kujolise ekuphuculeni umaleko we-oxide okhuselayo, ukuphucula ukumelana nokugqwala. Ukuqonda la mahluko kubalulekile ekukhetheni indlela efanelekileyo yonyango ngokusekelwe kwisicelo esithile kunye neemeko zokusingqongileyo.
Isiphelo
KwiJindalai Steel Company, siyaqonda ukuba unyango lomphezulu wentsimbi engagqwaliyo aluyonto nje inyathelo kwinkqubo yokwenziwa; yinxalenye ebalulekileyo emisela ixesha elide kunye nokusebenza kwemveliso yokugqibela. Ngokusebenzisa ubuchwepheshe obuphambili bonyango lomphezulu wentsimbi engagqwaliyo, kubandakanya ukuqhobosha kunye nokudlulisa i-passivation, siqinisekisa ukuba iimveliso zethu ziyahlangabezana nemigangatho ephezulu yomgangatho kunye nokuqina. Nokuba ufuna intsimbi engagqwaliyo yokwakha, yeemoto, okanye nakweyiphi na enye imboni, ubuchule bethu kwiinkqubo zonyango lomphezulu wesinyithi buqinisekisa ukuba ufumana izisombululo ezilungileyo kwiimfuno zakho.
