Isidingo sokwakha nokukhiqiza singahamba ngendlela ehlukile, kuyilapho izindleko zezinto ezingavuthiwe zithinta izingcaphuno zensimbi. Kubathengi, lokhu kwenza ukuqhathanisa okufanayo kube okubalulekile: ikhoyili yensimbi ye-Galvalume iwusizo kuphela uma ukunamathela, ukuqedwa, ubukhulu, kanye nokusetshenziswa okuhlosiwe kucaciswe ngokucacile.Ga

Izintengo zensimbi nokufunwa kungashintsha ngezinguquko kumsebenzi wokwakha, ama-oda okukhiqiza, nezindleko zempahla eluhlaza. Kubathengi abavela kwamanye amazwe nabakhi, ukucaciswa kobuchwepheshe okucacile kwenza amakhotheshini abahlinzeki abe lula ukuwaqhathanisa.

Osonkontileka bavame ukubuka i-zinc ependiwe njengokugembula okukhulu. Uhlala uzwa izindaba zemboni mayelana nokuxebuka okuyinhlekelele kanye nokwehluleka ukunamathela okwenzeka phakathi nezinyanga zokuphothulwa kwephrojekthi. Ukungabaza kuyaqondakala ngokuphelele. Nokho, iqiniso licacile: yebo, ungakwazi ukudweba ngempumelelo. Ngo-

Ukukhetha phakathi kwensimbi ethathiwe nensimbi engagqwali akuvamile ukuba kube impikiswano mayelana nokumelana nokugqwala. Kuyisabelomali sokulinganisa isinqumo sezinga eliphezulu, ukuphepha kokwenziwa, kanye nesikweletu sokusebenza. Yonke iphrojekthi yobunjiniyela idinga ukunemba okwedlulele ukuze iphumelele. Ukukhetha insimbi engalungile kuvame ukuholela ku-

Yebo, insimbi enothayela inozibuthe kakhulu. I-carbon steel core ibeka izici zayo ze-ferromagnetic cishe ngokuphelele. Phakathi naleso sikhathi, ungqimba oluncane lwangaphandle lwezinc lunomphumela omncane wokuvikela. Kufanele uqonde le mpahla ngokunembile ukuze wenze izinqumo eziphusile zobunjiniyela. M

Insimbi engaphekiwe isalokhu iyisici esiyisisekelo ekwakhiweni kwezimboni zesimanje nasekukhiqizeni. Ochwepheshe abaningi ngephutha bacabanga ukuthi le nto eqinile ayinakho ukonakala ngokuphelele. Eqinisweni, iyagqwala ngokuhamba kwesikhathi, kodwa ikufeza lokhu ngomklamo othile wobunjiniyela. Kusukela ngo
